High and low temperature resistant antibacterial infusion tube applied to medical treatment and preparation method thereof

Abstract

The invention discloses a high andlow temperature resistant antibacterial infusion tube applied to medical treatment. The infusion tube is prepared from the following raw materials of polyvinyl chlorine, high-performance polyolefin thermoplastic elastomer material, para aminobenzoic acid, m-phenylene dibenzoate, epoxidized soybean oil, hydroxyl magnesium carbonate, dihydro-quinoline, calcium salt, zinc salt, vanillic aldehyde, quaternary ammonium salt, chitosan, poly nitrogen cation, poly phosphorus cation and antioxidant BHT. The high and low temperature resistant antibacterial infusion tube applied to medical treatment has the advantages of being soft, not prone to being oxidized, large in elasticity, not prone to being broken, high-low-temperature-resistant and suitable for the field for producing infusion tubes and infusion bags.

Description

technical field [0001] The invention relates to a high and low temperature resistant antibacterial infusion tube for medical treatment and a preparation method thereof. Background technique [0002] The infusion tube is a common medical consumable. After aseptic treatment, a channel between the vein and the liquid medicine is established for intravenous infusion. It is generally used for connecting components of eight parts such as intravenous needles or injection needles, needle shields, infusion hoses, liquid medicine filters, flow rate regulators, drip pots, bottle stopper piercers, and air filters. [0003] However, the existing infusion tubes are easy to harden after being made, which affects the use effect of the device, and these infusion tubes cannot withstand strong pulling during processing. Once pulled, they are prone to leaks and are easy to break. For other medical supplies, it is usually used to store liquid medicine, and when it is refrigerated or kept warm, ...

AI Technical Summary

Problems solved by technology

[0003] However, the existing infusion tubes are easy to harden after being made, which affects the use effect of the device, and these infusion tubes cannot withstand strong pulling during processing. Once pulled, they are prone to leaks and are easy to break. For other medical supplies, it is usually used to store liquid medicine, and when it is refrigerated or kept warm, the material of the feeding tube cannot withstand low or high temperature, and it is easy to harden, which is not conducive to use after taking it out

[0004] Therefore, in summary, the existing material delivery pipes have problems such as easy solidification and oxidation of the pipe body, small elasticity and easy breakage, and resistance to high and low temperature differences.
