Intravenous infusion set is a common medical consumable, which is aseptically processed to establish a channel between the vein and the liquid medicine for intravenous infusion. CMC takes you to understand the material, usage, working principle and operation of the disposable sterile intravenous infusion set.
Disposable sterile intravenous infusion set is generally composed of eight parts connected by intravenous needle or injection needle, needle cap, infusion hose, liquid medicine filter, flow rate regulator, drip pot, cork puncture device, and air filter. Some infusion sets also have injection parts, dosing ports, etc.
Materials for making disposable intravenous infusion sets
Traditional infusion sets are made of PVC, and high-performance polyolefin thermoplastic elastomer (TPE) is considered to be a safer and higher-performance material for making disposable infusion sets. There is now a material that is DEHP free and is being rolled out nationwide.
Use of Disposable Intravenous Infusion Sets
The disposable sterile intravenous infusion set is used together with the disposable intravenous infusion needle, and is mainly used for clinical gravity infusion.
How Disposable Intravenous Infusion Sets Work?
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.
Infusion is a high-dose injection injected into the human body through an intravenous drip, usually packaged in a glass or plastic infusion bottle or bag, which does not contain preservatives. The dripping speed is adjusted and controlled by the infusion device, and it enters the human vein at a uniform speed to supplement the body fluids and electrolytes needed by the human body and provide nutrients for the human body.
The infusion set mainly relies on the action of gravity. The liquid enters the blood vessels of the human body from top to bottom due to the action of gravity. There is also the principle of negative pressure. Most of the fever symptoms caused by colds are caused by the weakened ability of the body to resist the disease. It is reasonable for doctors to recommend treatment by infusion, and the treatment effect is more direct and effective by direct administration into a vein.
How to operate a disposable intravenous infusion set?
Before use, medical staff check the disinfection validity period of the disposable infusion set and whether there is air leakage or other abnormalities in the packaging, take out the infusion set, and insert the bottle insertion needle part into the infusion bottle (if it is an infusion bag, unless the air inlet tube and the bottle insertion needle are integrated. Infusion set, otherwise there is no need to open the air inlet device, that is, insert the air inlet needle or open the air inlet hole), hang the infusion bottle on the infusion rod, exhaust the air until the liquid flows to the lower end of the infusion tube, close the regulator, and then insert the intravenous needle Puncture the sterilized vein, and after fixing it, untie the tourniquet and adjust the flow rate.
Precautions for the use of disposable intravenous infusion sets
1. It is a disposable product and should meet the corresponding national hygiene and quality standards.
2. Cross-use is prohibited.
3. Disposable infusion sets should be disposed of as medical waste after use.
