AI Technical Summary

Problems solved by technology

This layer of biofilm can absorb nutrients, has a certain thickness, and produces strong drug resistance, which cannot be eradicated by traditional antibacterial treatments.
The resulting infection and other symptoms have caused a significant burden on the clinical operation and the patient's economy

Abstract

The invention discloses a medical latex film. The medical latex film comprises, by weight, 0.01-1% of nano-silver, 0.2-3% of water-soluble chitosan, 0.5-5% of sericin, 10-40% of waterborne polyurethane and the balance natural latex. According to the medical latex film, the escaping concentration of extractable protein can be obviously reduced, the film has a compact structure, and the surface is more flat and smoother.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a medical latex film. Background technique [0002] Natural latex is a natural and renewable water-based dispersion system. Rubber products made of natural latex have excellent comprehensive properties and irreplaceability, and have been widely used in medical and health fields, such as medical catheters, gloves and condoms. However, natural latex products still have some performance defects, for example, natural latex products have poor compactness, aging resistance, and antibacterial properties. What's more serious is that latex contains some allergenic proteins, which can easily induce immediate allergic reactions such as contact dermatitis, urticaria, and allergic asthma. In severe cases, it can cause anaphylactic shock and even death. [0003] Many studies in recent years have shown that 45% of the infections caused by medical biomaterials are due to the adsorption of fib...
