1. First generation: Willow needle
It is made of a single piece of metal foil. The needle is 3~4cm long and looks like a willow. The head has a fixed length needle tip. The length is about 2~3mm. The bottom of the needle tip is enlarged to control the depth of the needle. The groove extends from the tip of the needle to the end of the needle. Easy to package and easy to be contaminated.
2. Second generation: plastic compression molding needle
It is molded in plastic and the tip is made of metal such as stainless steel. Each needle is equipped with a plastic needle cap for more independent packaging. Remove the needle cap before use to prevent contamination, the needle is small, the operation will be appropriate, the pain of the patient will be reduced, and the patient’s psychological pressure can be alleviated; the price is low and can be used once.
The common shortcomings of the first and second generations: strong pain, the size of the wound mainly depends on the experience and professional quality of the clinical laboratory staff. The patient’s wound is too close to the staff’s fingers or gloves, and there is still the possibility of cross-contamination of blood between patients.
3. The third generation: mechanical blood collection needle
The mechanical device is used, and the needle is equipped with an ejection device, which can almost completely achieve accurate, rapid, moderate and shallow, straight path piercing the skin, greatly reducing the pain of the patient. Basically solved the problems of strong pain and large wounds in the first two generations of blood collection needles.
This generation of blood collection needles has a pistol type, a pen type, etc.
4. Fourth generation: laser blood collection needle
Using the powerful energy of the laser, the tissue is burned in an instant and penetrates the skin to form a bleeding point. The blood collection instrument creates a minimally invasive wound that can be adjusted to the patient’s skin condition (which can be achieved by adjusting the laser intensity). In addition, the blood collection instrument has no actual physical contact with the patient, and even if a small blood spot is ejected, the blood cross-contamination can be completely eliminated by replacing the laser emitting head, which is a safe blood collecting instrument.
Laser blood collection needles have different shapes, large and small, large such as microscope, small cigarette box, can be used for blood collection in the clinic and bedside blood collection. It is only during the blood collection process that the laser lancet will make a creaking sound, and at the same time it will emit a slight smell of burnt flesh, which makes some patients feel uneasy.
