Needle-free connectors have been introduced into clinical practice to prevent accidental needle stick injuries and related blood-borne infections. The needle-free connector includes a separating diaphragm device and a mechanical valve. According to the function of the internal diaphragm or valve, mechanical valves are divided into neutral, negative and positive types. Some studies have reported that mechanical valves, especially positive displacement valves, can reduce thrombotic catheter blockage based on their valve function to prevent blood from returning to the intravascular catheter.

The needleless connector is made of lightweight plastic that is waterproof, mouldable, and immune to chemicals, silicone, polyester, and stainless steel (sometimes unaffected). There are several significant design differences, functional differences and characteristic differences between the various types of needleless systems.
The outside of the needle-free valve will become transparent or opaque and have a flat, concave, sunken, or centrally angled connection surface. In order to maximize the chance of sterilization, the ideal design of the needleless connector is a smooth diaphragm surface with almost no gaps or bumps.
If there is a tight seal connection between the diaphragm and the needleless valve, the possibility of contamination will be greatly reduced. Other features of the needleless connector are no clamping sequence, straight and clear fluid passages, transparency, almost no or no blood return, and can only be washed with saline.

For the current mould field, what are the design and manufacturing processes used? If you are a practitioner in this industry, then you must have an in-depth understanding of this knowledge. Let’s take a look at the detailed Content!
First, casting processing
Most people should be familiar with the casting process, or to a certain extent, most people think that all moulds are produced by casting processing. In fact, in the process of mould design and manufacturing, now This production and manufacturing process is not very suitable because it may lead to poor thermal conductivity of the mould, so it will affect the production efficiency of the mould. The most important thing is that through this casting method, it may also affect the steel. Strength and hardness.
Second, cutting
For those moulds that must ensure that the corners have a certain excessive rounded corners, cutting can be used in the production process, because it can effectively guarantee that there is a certain arc at the corners. Of course for this In terms of technology, it also has certain defects. For example, in the process of processing, it is likely that the stress concentration will occur due to the small radius being too small, which further damages the materials used, and may also It will cause the appearance of this mould to be too rough after processing, which is also an important aspect.
Third, grinding
This is a mould design and manufacturing process that is often used at present, because for this production process, it can effectively improve the quality and level of moulds. The most important thing is that some moulds have higher requirements for precision, especially The requirements for the smoothness of the mould surface are also strict, so in this case, in some cases where the requirements are relatively high, this tool can be used to complete the mould design and manufacturing work. However, when applying this process, More measures need to be taken to avoid overheating or cracks.
Fourth, EDM
In fact, for most of the mould manufacturers, in the process of designing and manufacturing various moulds, due to the relatively high precision requirements for the moulds, the EDM process seems to be more and more popular, after all, through CNC The technology can achieve higher precision when controlling EDM, and at the same time can ensure that the surface has a certain smoothness. However, when applying this mould design and manufacturing process, it must also ensure that the operator has a certain technical level, or that This process has certain requirements for technical level.

Medical plastic oxygen masks are mainly used by medical service providers for oxygen therapy because they are disposable, so cleaning costs and infection risks can be reduced. The design of the mask can determine the accuracy of the oxygen delivered in many medical situations that require oxygen therapy. 21% of oxygen is naturally produced in indoor air, and a higher percentage is usually essential in medical treatment. These higher percentages of oxygen are classified as drugs, where too much oxygen may be harmful to the patient’s health, leading to dependence on oxygen for a period of time, and in extreme cases the patient is blind. For these reasons, oxygen therapy is closely monitored. The mask is lightweight and can be fixed with an elastic headband or ear rings. They are transparent, allowing medical staff to visualize the face for patient evaluation and reduce the feeling of claustrophobia experienced by some patients while wearing an oxygen mask. Most surgical patients wear oxygen masks at some stage. They may wear a nasal cannula, but the oxygen delivered in this way is less accurate and limited in concentration.

Coordinated change of mould convex, concave mould and auxiliary forming system. It can process plastic parts of different shapes and sizes. In the plastics processing industry, it is matched with plastic moulding machines to give plastic products complete tools and precise dimensions. Due to the variety of plastics and processing methods, the structure of plastic moulding machines and plastic products is also complicated, so the types and structures of plastic moulds are also diverse.
With the rapid development of the plastics industry and the continuous improvement in strength and other aspects of general and engineering plastics, the application range of plastic products is also expanding, and the amount of plastic products is also rising.
Plastic mould is a tool for producing plastic products. It is composed of several groups of parts, and there is a moulding cavity in this combination. During injection moulding, the mould is clamped on the injection moulding machine, the molten plastic is injected into the moulding cavity, and cooled and shaped in the cavity, then the upper and lower moulds are separated, and the product is ejected from the cavity through the ejection system to leave the mould, and finally the mould is closed. For the next injection, the entire injection process is cyclic.
The general plastic mould is composed of a movable mould and a fixed mould. The movable mould is installed on the moving mould of the injection moulding machine, and the fixed mould is installed on the fixed mould of the injection moulding machine. During injection moulding, the movable mould and the fixed mould are closed to form a pouring system and a cavity. When the mould is opened, the movable mould and the fixed mould are separated to take out the plastic product.
Although the structure of the mould may vary due to the variety and performance of plastics, the shape and structure of plastic products, and the type of injection machine, the basic structure is consistent. The mould is mainly composed of pouring system, temperature adjustment system, moulding parts and structural parts. Among them, the pouring system and the moulded parts are the parts that are in direct contact with the plastic, and change with the plastic and the product. They are the most complex and the most varied parts in the mould, which require the highest processing finish and precision.
The pouring system refers to the part of the flow path before the plastic enters the cavity from the nozzle, including the main flow path, the cold material cavity, the flow path and the gate. moulded parts refer to various parts that form the shape of the product, including moving mould, fixed mould and cavity, core, moulding rod and exhaust port.
Driven by the high-tech drive and application requirements of pillar industries, China’s plastic moulds have formed a huge industrial chain, from upstream raw and auxiliary materials industry and processing, testing equipment to downstream machinery, automobiles, motorcycles, home appliances, electronic communications , Building materials, and other major application industries, plastic mould development is alive.

Steps For Using Three Way Stopcock
2020年6月17日The venous (IV) dropper was connected to the Y port injection port three-way stopcock without changing the direction, causing the drug solution to pause for 30 minutes. After the syringe pump blockage alarm sounded, an error was found.
The patient end of the three-way stopcock is temporarily closed for operation. Because the flow of the patient is not connected, the infusion pump is blocked and the alarm is turned on again after the completion of the alarm procedure.
When using a three-way stopcock, check the position of the stopcock/rod.
In many cases, it is necessary to confirm the position of the cock/rod. Develop a habit, confirm the flow of the drug solution after each use and operate the three-way stopcock.
The fluid paths indicating "closed" and "opened" For the 1 and 3 lever models, the cock/rod positions are reversed
Type the stopcock. Make sure to confirm the fluid channel and cock/rod.
Do not rotate 180°
Plug valve exceeds 180°! , May cause the drug solution to leak)
Connect the stopper/valve and intravenous drip tube to the three-way stopcock valve to administer antibiotics. After administration of antibiotics, the stopper and intravenous drip accidentally removed the tube and the patient’s blood leaked
When removing the IV tube from the three-way stopcock, make sure not to accidentally remove the stopper/valve.
It is good to have a "three-way plug valve" with a built-in plug/valve. Be sure to check whether the plug valve you are using has a built-in plug/valve.
Several three-way stopcock valves are connected to the central venous catheter. After lying down for a period of time, the connection between the three-way cock was loose, and blood and infusion leaked.
If you need to connect multiple three-way stopcocks together, please be cautious about joints loosening and breaking the body due to being squeezed or pulled. Regularly check whether the joints or fluids are loose and/or displaced
Leaks, etc.
When the three-way stopcocks are connected together, there is joint breakage or looseness. Avoid connecting tees

A Vaginal Speculum (sometimes called a vaginal trainer) is a tool used to gently stretch the vagina. They are used when the vagina is narrowed (vaginal stenosis), for example after brachytherapy for gynecological cancer, and in the treatment of vaginal cramps and other forms of intercourse difficulties.
There is evidence of mixed use, and studies have reported psychological damage caused by dilator therapy. Rectal vaginal fistula is also related to the use of dilators.
Vaginal Speculums (also known as vaginal stents) are commonly used in postoperative care for patients who have undergone gender redistribution surgery. Immediately after the operation, the dilator was used to keep the channel unhealed, and thereafter the dilator was used regularly to maintain the viability of the new vagina. The frequency of use requirements decreases with the passage of time, but must be observed throughout life.

According to different moulding methods, plastic processing mould types corresponding to different process requirements can be divided, mainly including injection moulding moulds, extrusion moulding moulds, plastic moulding moulds, high-foam polystyrene moulding moulds, etc.
1. Plastic injection (plastic) mould
It is mainly a moulding mould most commonly used in the production of thermoplastic plastic parts. The processing equipment corresponding to plastic injection moulds is a plastic injection moulding machine. The plastic is first heated and melted in the heating barrel at the bottom of the injection machine, and then in the screw of the injection machine. Or pushed by the plunger, enter the mould cavity through the injection system of the injection machine nozzle and the mould, the plastic is cooled and hardened, and the product is released from the mould. Its structure is usually composed of moulded parts, pouring system, guide parts, ejection mechanism, temperature adjustment system, exhaust system, support parts and so on. The manufacturing materials are usually plastic mould steel modules. The commonly used materials are mainly carbon structural steel, carbon tool steel, alloy tool steel, high-speed steel, etc. The injection moulding processing method is usually only suitable for the production of thermoplastic products. The plastic products produced by the injection moulding process are very wide. From daily necessities to various complicated machinery, electrical appliances, vehicle parts, etc., are formed by injection moulding. It is the most widely used processing method in the production of plastic products.
2. Plastic compression mould
Including compression moulding and injection moulding two structural mould types. They are a type of mould mainly used for moulding thermosetting plastics, and the corresponding equipment is a pressure moulding machine. According to the characteristics of plastics, the compression moulding method heats the mould to the moulding temperature (generally between 103 ° and 108 °), and then puts the measured compression moulding powder into the mould cavity and the charging chamber, and closes the mould. It is softened and viscous, solidified and shaped after a certain period of time, and it becomes the desired product shape. The difference between compression injection moulding and compression moulding is that there is a separate feeding chamber. Before moulding, the mould is closed first. The plastic is preheated in the feeding chamber in a viscous state. Under pressure, it is adjusted into the mould cavity and hardened. Compression moulds are also used to mould some special thermoplastics such as difficult-to-melt thermoplastics (such as polyvinyl fluoride) blanks (cold compression moulding), resin lenses with high optical performance, slightly foamed nitrocellulose automobile steering wheels, etc. . Compression mould is mainly composed of cavity, feeding cavity, guide mechanism, ejecting parts, heating system and so on. Pressure injection moulds are widely used to encapsulate electrical components. The materials used in the manufacture of compression moulds are basically the same as injection moulds.
3. Plastic extrusion die
A type of mould used to produce continuous-shaped plastic products, also known as extrusion moulding heads, is widely used in the processing of pipes, rods, monofilaments, plates, films, wire and cable coatings, and shaped materials. The corresponding production equipment is a plastic extruder, the principle of which is that solid plastic is melted and plasticized under the conditions of heating and screw rotation and pressure of the extruder, and is made into a cross-section with the shape of the die by a specific shape Continuous plastic products. Its manufacturing materials mainly include carbon structural steel, alloy tools, etc. Some extrusion dies are also inlaid with diamond and other wear-resistant materials on the parts that need to be wear-resistant. Extrusion process technology is usually only applicable to the production of thermoplastic products, which is significantly different from injection moulds and compression moulds in structure.
4. Plastic blow mould
It is a mould for moulding hollow products of plastic containers (such as various packaging containers such as beverage bottles and daily necessities). The form of blow moulding mainly includes extrusion blow moulding hollow moulding and injection blow moulding hollow moulding according to the process principle. , Injection stretch blow moulding hollow moulding (commonly known as "injection stretch blow moulding"), multilayer blow moulding hollow moulding, sheet blow moulding hollow moulding, etc. The equipment corresponding to the blow moulding of hollow products is usually called a plastic blow moulding machine. Blow moulding is only suitable for the production of thermoplastic products. The structure of the blow mould is relatively simple, and the materials used are mostly made of carbon.
5. Plastic blister mould
It is a mould that uses plastic plates and sheets as raw materials to form some simpler plastic products. The principle is to use vacuum blooming methods or compressed air forming methods to make the plastic plates and sheets fixed on the concave or convex mould. Under the condition of heating and softening, it deforms and sticks to the cavity of the mould to obtain the desired moulded product, which is mainly used in the production of some daily necessities, food, and toy packaging products. The plastic mould has lower pressure during moulding, so the mould material is mostly made of cast aluminum or non-metallic materials, and the structure is relatively simple.
6. High foam polystyrene mould
It is a mould that uses expandable polystyrene (beads composed of polystyrene and foaming agent) to form foam packaging materials of various shapes. The principle is that expandable polystyrene can be steam-formed in the mould, including two types of simple manual operation mould and hydraulic machine straight-through foam plastic mould. It is mainly used to produce packaging products for industrial products. The materials for manufacturing such moulds are cast aluminum, stainless steel, bronze and so on.

The design and manufacture of syringe moulds are closely related to plastic processing. The success or failure of plastic processing depends largely on the mould design effect and mould manufacturing quality, and the plastic mould design is based on the correct plastic product design.
The structural elements to be considered in the plastic mould design of the syringe are:
①Parting surface, that is, the contact surface of the concave mould and the convex mould when the mould is closed. The choice of its position and form is affected by factors such as product shape and appearance, wall thickness, moulding method, post-processing technology, mould type and structure, demoulding method and moulding machine structure.
②Pouring system, that is, the feed channel from the nozzle of the injection moulding machine to the cavity, including the main channel, the branch channel, the gate and the cold cavity. In particular, the location of the gate should be selected so that the molten plastic fills the cavity in a good flow state. The solid runner and the cold material attached to the product are easily ejected from the mould and cleared when the mould is opened (heat flow) (Except Daomo).
③Plastic shrinkage and various factors that affect the dimensional accuracy of products, such as mould manufacturing and assembly errors, mould wear, etc. In addition, when designing compression moulds and injection moulds, the matching of the process and structural parameters of the moulding machine should also be considered. Computer-aided design technology has been widely used in plastic mould design.

When mass production of some medical device parts and plastic products in many factories, in order to ensure that the products produced are not different in size and shape, and also to further improve production efficiency, it is necessary to use moulds at this time Production, but for those who need to use moulds, they just know how these moulds are used, but they don’t know that in the process of mould processing and manufacturing, they also need to meet many strict requirements, so the mould processing requirements are all What is included?
First, the wear resistance must be outstanding
Although there are a lot of needs for moulds now, the factory and the internal staff do not know what the mould processing requirements are, but they know that in the process of using the mould, each use will cause certain friction to the mould itself. Although the mould itself has a certain strength and hardness, and wear resistance is also outstanding, but in the process of long-term use, its wear will become more and more obvious, this time may even affect the shape and size, Therefore, it has a very important influence on the mould processing requirements, that is, it must improve the wear resistance of the mould through various production processes and high-quality raw materials, because only in this way can it really extend its service life.
Second, strong fatigue fracture performance
Anyone who has studied mechanics should be able to know that all kinds of metal materials have a yield stage in the process of stretching or stress, and finally include the fatigue stage. In these two stages, its height and There will be obvious changes in strength, and even some materials may experience fractures in some minor history. Therefore, in order to avoid moulds in the process of use, fractures or various serious problems often occur. During the process, it is necessary to meet the mould processing requirements. In this case, it is necessary to find a way to improve its fatigue fracture performance. In this way, it can effectively avoid fracture under the action of conventional forces.
Third, resist the effects of temperature changes
Needless to say, most people should be able to know that when using a mould for production, it is necessary to inject a melt of various raw materials into the mould, and if you want to turn various materials into a melt, you must To increase the temperature, when these melt materials are just injected into the mould, the mould will also be heated, and there will be certain deformation, and during the cooling process, the temperature of the mould itself will also change, so in the production process Among them, we must find ways to improve its ability to resist the influence of temperature through various methods. Today it meets the requirements of mould processing. Since then, in each product production cycle, the size and accuracy of the product can be effectively controlled. In this way, the products produced can truly meet the needs of use.
These are some of the more important mould processing requirements. If they can meet these requirements, the moulds produced can generally achieve higher quality, so many excellent companies now generally design and produce in strict accordance with these requirements. .

According to the design of the oxygen delivery device, there are usually three basic styles: low flow, gas storage tank and high flow. Regarding the range of oxygen uptake fraction (FiO2), the oxygen system can be divided into those indicated by low oxygen ( 60%). Some devices can provide a wide range of oxygen percentages. When choosing an oxygen delivery device or an oxygen mask, the two most important questions that a respiratory therapist must address are: how much oxygen the mask can deliver, and whether the weather-resistant FiO2 delivery is stable, or changes with breathing patterns.
Now we will review different oxygen delivery masks, clinical indications and usage.
1. Use of Nasal Catheters-Low Flow Delivery
The low-flow oxygen delivery system consists of a nasal cannula, a nasal tube, and a tracheal tube. They are designed to provide supplemental oxygen, which is usually less than the patient’s total minute ventilation. Because the patient’s minute ventilation exceeds the flow rate, the oxygen delivered by the device will be diluted by the ambient air, so less than expected oxygen is inhaled.
A standard nasal cannula provides 24-44% FiO2 at a supply flow of 1-8 liters per minute (LPM). The formula is FiO2 = 20% + (4 x oxygen flow rate). FiO2 is affected by breathing rate, tidal volume, and pathophysiology. The slower the inspiratory flow, the higher the FiO2; the faster the inspiratory speed, the lower the FiO2. Nasal intubation is not recommended for acute severe hypoxemia because the percentage of oxygen delivered is very inconsistent. The patient’s upper airway serves as an oxygen reservoir for the nasal catheter. For flow rates greater than 4 LPM, a humidifier is recommended to ensure that the dry inhaled gas is humidified. Nasal intubation is best for patients who have a relatively stable breathing pattern, require a low percentage of oxygen, or require supplemental oxygen during surgery or diagnosis, or for home care.
2. Simple oxygen mask or non-breathing oxygen mask-gas storage system
The gas storage system collects and stores oxygen during inspiration and expiration. When the patient’s tiny ventilation flow exceeds the device delivery flow, they can withdraw gas from the reservoir at any time. To increase the oxygen concentration delivered, a mask reservoir is usually used. The volume of the oxygen mask is approximately 100-300 cm3, depending on the size. It can provide 40-60% FiO2 at 5-10 liters. FiO2 is affected by breathing rate, tidal volume, and pathology. Masks are also a good choice for patients with nasal irritation or nasal st or severe breathing. Due to the low humidity delivered and the drying effect of oxygen, a simple oxygen mask should only be used for a few hours. This device is best suited for short-term emergencies, surgical procedures.
When FiO2> 40% is needed and used for acute desaturation, a non-breathable oxygen mask should be used. At flow settings greater than 10 liters, it can deliver up to 90% of FiO2. This device is best suited for acute cardiopulmonary emergencies requiring high FiO2. For patients requiring precise and high oxygen percentages, the device should be used for less than four hours due to insufficient humidity delivery and variable FiO2.
3. Venturi oxygen mask or aerosol mask-high flow delivery
The high-flow oxygen delivery system provides a given oxygen concentration at a flow equal to or exceeding the patient’s inspiratory flow requirement. If the delivered flow exceeds the total patient flow, accurate FiO2 delivery can be achieved.
When the venturi hood mixes oxygen with room air, it can produce high-flow oxygen-enriched oxygen at the required concentration. It produces accurate and constant FiO2 with oxygen concentration levels usually set to 24%, 28%, 31%, 35% and 40%, respectively. Venturi hoods are often used when clinicians are concerned about CO2 retention or inconsistent respiratory drive. It is commonly used in the population of patients with COPD, and the risk of knocking out patients with hypoxic drivers needs to be considered.
Depending on the setting, the aerosol-generating device can transfer the content of FiO2 from 21% to 100%. The flow rate is usually set to 10 LPM by adjusting the clips on the top of the aerosol container to select the FiO2 required. A humidity device is connected to the flow meter and a wide-bore tube connects it to the patient’s mask. The wide-bore pipe and the gas storage bag are placed in a line to act as an oxygen reservoir to ensure accurate high FiO2 is provided. The device increases the moisture content for patients and helps liquefy residual secretions. This oxygen delivery option is ideal for tracheostomy patients because it allows the inhaled air to be oxygenated, humidified, and even heated if necessary. They can be attached to aerosol masks, tracheostomy masks, and even T-pieces. During inhalation, you should see aerosol spray from the mask or container. To ensure accurate oxygen distribution through this system, an oxygen analyzer should be used. The device can be used to ensure accurate oxygen delivery and maintain humidity in the artificial respiratory tract.
The best oxygen delivery results usually depend on choosing the right oxygen delivery equipment. When choosing an oxygen delivery device, the respiratory therapist should include the following in their recommendations: the goal of the oxygen delivery, the patient’s condition and cause, and the performance of the selected device.

In-mould injection moulding is to combine the individual components into a whole in the mould, instead of assembling the components by fastening, welding or bonding outside the mould, greatly reducing the chance of contamination of medical plastic components. .
The equipment used for in-mould assembly is not much different from other multi-component moulding equipment. The main difference is that in-mould assembly integrates automatic operation and subsequent operation steps, which can ensure the repeatability and accuracy of processing. Closed-loop control system.
In-mould assembly injection moulding produces medical plastic device components that cannot be moulded by conventional methods. Various forms of in-mould assembly promote the technological progress of medical plastic devices. Medical mould company assembles and produces plug filters of liquid silicone rubber and PBT incompatible materials. The medical mould company uses overmould assembly and injection moulding. The materials of the three components are PC, PP, and TPE, and a medical valve with a rotating center mechanism is formed.
In-mould assembly injection bottle cap injection equipment. The cap is an important part of the bottle, which is directly related to the shelf life and quality of the drug. The plastic bottle cap developed with the metal bottle cap concept has lower performance than the metal bottle cap, and there is also a problem of sealing performance for the infusion bottle cap. The development of double-layer composite high-performance sealed bottle caps is an urgent problem. The inner layer of the bottle cap is a plastic with high barrier properties and excellent sealing performance, and the outer layer is a high-strength plastic. The two layers of plastic are independently moulded and moulded at one time through independent moulding in the mould.
Many unique technologies and applications for in-mould assembly are more innovative applications in moulds than improvements in moulding equipment. In-mould assembly injection moulding moulds are still blank in China. China still only stays in injection moulding of ordinary multi-color / multi-component injection moulding of some low value-added domestic products. There is no step forward in the injection moulding of high-tech plastic products that cannot be manufactured by other processing methods. Field, which hinders the application and development of plastic products and the scientific and technological progress of related industries, while not obtaining high economic benefits.

Various forms of in-mould assembly promote the technological progress of medical plastic devices. Medical mould company assembles and produces plug filters of liquid silicone rubber and PBT incompatible materials. The medical mould company uses overmould assembly and injection moulding. The materials of the three components are PC, PP, and TPE, and a medical valve with a rotating center mechanism is formed.
In-mould assembly injection bottle cap injection equipment. The cap is an important part of the bottle, which is directly related to the shelf life and quality of the drug. The plastic bottle cap developed with the metal bottle cap concept has lower performance than the metal bottle cap, and there is also a problem of sealing performance for the infusion bottle cap. The development of double-layer composite high-performance sealed bottle caps is an urgent problem. The inner layer of the bottle cap is a plastic with high barrier properties and excellent sealing performance, and the outer layer is a high-strength plastic.

After radiation treatment: If a woman is undergoing radiation therapy to or near the vagina, a dilator is usually given at the end of the treatment. First, the use of a dilator helps prevent vaginal walls from sticking to each other and closing scars during healing. As healing progresses, radiation can cause fibrosis in the vaginal wall (scar formation process). Using a dilator or having a total of 2-3 sexual intercourse a week can help the vagina stay as deep and wide as possible. Repeatedly, studies have shown that most women do not follow the usual recommendations, using a dilator or having sexual intercourse 3 times a week, even within months after radiotherapy, or even months after radiotherapy, despite scars remaining after that It continues, but it is missing for many years.
After vaginal reconstruction: If a woman undergoes surgical reconstruction of the vagina due to birth defects, future health problems, or cancer treatment, a vaginal dilator can be tailored to her so that it can be used during sleep and within hours of sleep. Wear that day. The dilator helps the new vagina to be as deep and wide as possible during the healing process. If a skin graft is used to make the vagina, a dilator is most likely used. The vagina produced by the intestines or skin and muscle flaps may not require them.
To maintain vaginal size for long periods after menopause or cancer treatment:
Vaginal Speculum can help women maintain sufficient vaginal size and stretch for painless intercourse or pelvic examination after menopause. Dilators are also helpful during times when patients need anti-estrogen therapy for breast cancer. In addition, Vaginal Speculum are used to prevent scar formation during donor-to-stem cells or graft-versus-host syndrome after bone marrow transplantation.
Create vagina for young women who have no fetuses: Some women have no fetuses. Instead, they have a small "dimple", which is a dead end. When they reach adulthood, they can choose surgery to make the vagina or expand it. They press the dilator into the vaginal opening for about half an hour, twice a day. Within a few weeks, they can deepen their openness to have sex with a male partner. However, they must continue to use a dilator or perform regular sexual activities to maintain the vaginal canal. If their condition involves abnormally low hormone levels, they also use estrogen creams to improve elasticity in the vaginal area.
To treat fear of vaginal penetration: Some women have a strong fear of something entering the vagina. This problem is called vaginal spasm or pelvic floor myalgia. Sex therapists used to think that women with vaginosis would clenched vaginal muscles and could not penetrate. Recently, it has been recognized that the problem is phobia when a partner tries to insert a finger or penis into the entrance of the vagina. Muscle tension may coexist with fear, but not always. Women can often overcome vaginal spasms by practicing muscle relaxation while using a set of Vaginal Speculum of different sizes. The key factor is that a woman can control what goes into the vagina.

Syringe mould maintenance is more important than mould maintenance. The more times the mould is repaired, the shorter its life; the better the mould is maintained, the longer its service life.
The maintenance of the syringe mould is mainly divided into three points:
1. Daily maintenance of the mould: refueling of various moving parts such as thimbles, rows, guide posts, guide sleeves, cleaning of the mould surface, and clearing of water, which are maintained every day during mould production.
2. Regular maintenance: Regular maintenance includes cleaning the exhaust trough in addition to daily maintenance, trapped gas burned black level and exhaust, and correction of damage and wear parts.
3． Appearance maintenance: the outside of the mould is painted with paint to avoid rust. When the mould is lowered, the fixed mould moving mould should be coated with rust-proof oil. When the mould is stored, it should be closed tightly to prevent dust from entering the cavity.

Vaginal Speculums are used to restore vaginal volume, expand the width and depth of the vagina, provide elasticity to the tissue and allow comfortable sexual activity. Vaginal Speculums are smooth plastic, rubber or glass cylindrical objects with various scales and weights.
Vaginal dilatation may be required for certain medical conditions, including superficial dysmenorrhea, high pelvic floor dysfunction, vaginal spasm, induced vestibular instability, vaginal atrophy, vulvar skin disease, vaginal hypoplasia and post-radiation adhesions. Dilation can also be used as a conditional therapy for poor sexual intercourse.
Vaginal Speculums are usually sufficient to restore function, and dilator therapy is considered successful if the woman can resume comfortable intercourse or self-stimulation as needed. Vaginal dilatation can also be used as an adjunct to pelvic floor muscle physiotherapy, psychological therapy, sexual therapy, local vaginal estrogen therapy with minimal local absorption, intravaginal muscle relaxants, lubricants, humectants, and vibrators.
