The needle tube is PP, K4912 is medical special materials, yanshan petrochemical. I don't know about the infusion bag. One of the most commonly used disposable medical consumables used for the treatment of intravenous fluids and the establishment of a channel between venous and liquid medicine. It is composed of intravenous needle, protective cap, infusion hose, liquid filter, flow rate adjuster, drip pot, bottle stopper and air inlet air filter. The high performance polyolefin thermoplastic elastomer (TPE) is considered to be a safer and more reliable material for the production of a disposable infusion device. There is now a material that does not contain DEHP and is being promoted nationwide. Under the action of atmospheric pressure, the liquid in the bottle flows into the drip from the thinner infusion hose. When the pressure of the drip column is greater than the pressure of the vein, the liquid in the bottle flows down the tube to the vein.
Disposable syringe is made of PP material, medical grade.
Medical grade PP is a medical certificate, such as: comply with USP Class Ⅵ and ISO10993, was listed in the FDA's drug management files (DMF) and so on. Should have:
1. Multiple sterilization options (high pressure, hot steam, ethylene oxide, gamma ray, electron beam)
2. Excellent transparency and luster.
3. Excellent rigidity and resistance to impact resistance.
4. Good impact resistance of low temperature.
Food grade materials are mainly non-toxic, tasteless, pollution-free, medical treatment can be used for food, but food grade can not be used as medical grade.
