It is a common medical consumable. After aseptic treatment, a channel is established between the vein and the liquid medicine for intravenous infusion. Generally, it consists of eight parts: intravenous needle or injection needle, needle cap, infusion hose, liquid medicine filter, flow regulator, drip pot, bottle stopper puncture device and air filter. Some infusion sets also have injection parts and drug feeding ports.

Chinese name: disposable sterile infusion set mbth: disposable infusion set with needle specifications: single-wing infusion needle, double-wing infusion needle and needle use: clinical gravity infusion set specifications, manufacturing materials, product use, working principle, operation methods, precautions, instrument specifications: ordinary infusion set, barrel infusion set and bag infusion set. Traditional infusion sets are made of PVC, and high-performance polyolefin thermoplastic elastomer (TPE) is considered to be made. Now there is a DEHP-free material, which is being popularized all over the country. Usage: Air-intake infusion device product. This product is matched with disposable intravenous infusion needle, mainly used for clinical gravity infusion. Working principle Under the action of atmospheric pressure, the liquid in the bottle flows into the drip bucket along the thinner infusion hose. When the water column pressure of the drip bucket is greater than the venous pressure, the liquid in the bottle flows into the vein along the hose. Operation method: Before using the disposable infusion set, medical personnel should check the disinfection validity period and package for any abnormal conditions such as air leakage, take out the infusion set, insert the needle part into the infusion bottle (if it is an infusion bag, it is not necessary to open the air inlet device, that is, insert the needle or open the air inlet), hang the infusion bottle on the infusion rod, exhaust until the liquid medicine flows to the lower end of the infusion tube, close the regulator, and then insert the intravenous needle into the sterilized vein. Note: 1. It belongs to one-time use and should meet the corresponding national health quality standards. 2. Cross use is prohibited. 3. Disposable infusion sets should be treated as medical waste after use.
