A kind of medical composite material and its manufacturing process

Abstract

The invention relates to a medical composite material and its manufacturing process. The medical composite material is composed of polyethylene terephthalate fiber, carbon ion filament fiber, polyurethane film and auxiliary materials. The manufacturing process includes the manufacture of polyester filament fibers; the manufacture of conductive silk fibers; weaving polyester filament fibers and conductive silk fibers into textile materials with antistatic functions; the manufacture of antibacterial films; and the manufacture of medical composite materials. The medical composite material manufactured by the invention has a high degree of waterproof, anti-penetration, and anti-bacteria functions, completely eliminates the penetration of patient blood, body fluids, flushing fluids, and other pollutants, and realizes two-way protection functions; at the same time, it has good moisture permeability. Function.

Description

technical field [0001] The invention relates to a medical composite material and its manufacturing process, in particular to a medical composite material with the functions of waterproof, anti-penetration, anti-pollution, moisture permeation, anti-static, hypochlorite rinsing resistance, and non-flocculation-free functions. The manufacturing process belongs to the technical field of medical materials. Background technique [0002] In the prior art, commonly used materials for medical fabrics are cotton materials and disposable non-woven materials. [0003] Cotton material: Without basic barrier function, patient blood, body fluids and other pollutants are easy to soak into cotton material, resulting in cross-infection of medical staff and patients; a large amount of deflocculation occurs, which will cause wound infection and infection in large-scale medical institutions; Without the antibacterial function, it cannot provide the best safety protection for medical staff and p...

Problems solved by technology

[0003] Cotton material: Without basic barrier function, patient blood, body fluids and other pollutants are easy to soak into cotton material, resulting in cross-infection of medical staff and patients; a large amount of deflocculation occurs, which will cause wound infection and infection in large-scale medical institutions; Without the antibacterial function, it cannot give medical staff and patients the best safety protection; cotton operating room medical fabrics have been eliminated by developed countries in Europe and the United States

[0004] Disposable non-woven material: Although it has a certain barrier function, it cannot provide complete protection when encountering a large amount of pressurized blood, body fluids, and flushing fluid; the moisture vapor transmission rate is too low, and it is stuffy, which increases the workload of surgical medical staff Burden; high single-use cost; produces a large amount of medical waste, incineration will produce harmful substances such as dioxins, polluting the environment
