Study the pressure of the needleless infusion connector to provide a basis for clinical judgment and selection of the correct connector.
Method: Select 4 different infusion connectors, connect with 4F PICC, use a 10 ml syringe to inject the colored liquid into PICC, and reach the same length as the catheter (24 cm), then remove the syringe, observe and measure the liquid level in the catheter Range of change. Result: For the first connector, after removing the 10 ml syringe, the liquid level increased. From 24 cm to 30 cm; for the second connector, the liquid level drops from 24 cm to 19 cm after removing the 10 ml syringe; for the third connector; the liquid level decreases from 24 cm after removing the 10 ml syringe Reduced to 7 cm cm; for the fourth joint, the liquid surface was reduced from 24 cm to 22 cm.
Conclusion: For each infusion connector of different brands, the pressure is completely different. For the positive pressure infusion connector, the fluid will become freon. After the syringe is pulled out during the flushing and closing process, for the negative pressure infusion connector, the liquid will turn to the catheter connector, which will cause blood to flow back into the catheter It shows that it will not prevent it. Therefore, the correct needle-free infusion connector must be selected and used.
