The basic operation method of disposable transfusion device
The disposable transfusion device is a common medical consumable that is aseptically processed to establish a channel between the vein and the drug for intravenous infusion. Generally, it consists of eight parts: a venous needle or an injection needle, a needle cap, an infusion hose, a liquid medicine filter, a flow rate regulator, a drip pot, a bottle stopper, an air filter, etc. And some infusion sets and injection parts, add medicine and so on. Before using the medical staff, check the disinfection expiration date of the disposable infusion set and whether there is any leakage or other abnormality in the package. Take out the infusion set, insert the needle into the infusion bottle, hang the infusion bottle on the infusion rod, and vent until the liquid flows. At the lower end of the infusion tube, close the regulator, then puncture the venous needle into the sterilized vein. After fixing, release the tourniquet and adjust the flow rate.
The traditional infusion sets are made from PVC, and high-performance polyolefin thermoplastic elastomers are considered to be safer and higher performance materials for disposable infusion sets. There is now a material that is DEHP-free and is being promoted nationwide.
