Light-avoiding antibacterial infusion bag and preparation method thereof

Abstract

The invention relates to a light-avoiding antibacterial infusion bag. The light-avoiding bacteriostatic infusion bag has three layers, namely, the inner bag layer, the middle bag layer and the outer bag layer; the inner bag layer is an atactic polypropylene and / or block polypropylene resin material layer, the middle bag layer is a polyvinyl chloride resin material layer and the outer bag layer is a polyethylene material layer. According to the light-avoiding bacteriostatic infusion bag, a proper amount of light-avoiding agent is added in the middle bag layer, titanate modified nano silver oxide is added in the outer bag layer, and therefore the light transmitting rate of the light-avoiding bacteriostatic infusion bag is far lower than the standard required value, the light-avoiding effect is good, and the bag also has appropriate transmittance, helps medical staff observe infusion drug liquid in the infusion bag, avoids medical accidents and has a very good application prospect. Titanate modified nano silver oxide is capable of killing some viruses and bacteria in the sun, especially under ultraviolet rays, and has a good antibacterial effect.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a light-proof and antibacterial infusion bag and a preparation method thereof. Background technique [0002] During the infusion process, due to the different properties of the drugs, there are different requirements when using them. Some drugs will decompose when exposed to light, which will reduce the curative effect, such as some antineoplastic drugs, vasodilators, water-soluble vitamins, etc. Therefore, during the infusion process Light protection is required. Light-proof infusion is mainly aimed at some photosensitizing drugs, preventing them from denaturing or degrading under light, so as to affect the efficacy of the drugs. All black is the best way to avoid light, but it is not conducive to clinical observation of the infusion situation. The light-proof infusion set needs to have a certain degree of transparency. Therefore, the key to solving the problem of avoiding lig...

AI Technical Summary

Problems solved by technology

There are some light-shielding infusion sets on the market, but the light-shielding agent is dispersed in the infusion set catheter and the dripping funnel, and the inner surface of the infusion set catheter and the dropping funnel is in direct contact with the liquid medicine, which is prone to discoloration under the infiltration of the liquid medicine, resulting in Toxic and side effects, the safety of patients is difficult to guarantee

In addition, because there are many bacteria in the hospital, the infusion bag is easy to breed bacteria during use. If it causes a second infection to the patient, it will aggravate the patient's condition, and even threaten the patient's life.
