Introduction to the functions of medical non woven fabrics.
Medical non woven fabrics can be divided into protective medical products and functional medical products according to their uses. Protective medical supplies mainly refer to surgical gowns, masks, bed sheets, cover cloths, etc. Functional medical supplies mainly refer to gauze, bandages, sutures, artificial blood vessels, artificial internal organs, artificial skin, medical filter materials, and health care products. There is another classification method that is divided into indirect medical supplies and direct medical supplies.
Protection effect, cost and comfort are the three major elements of non-woven medical products. Protective medical products are products that are not used for direct treatment of patients. Their function is to improve the sanitary environment of the treatment area, prevent bacterial penetration and cause indirect infection and virus cross-infection, thereby improving the treatment effect and preventing other medical environments or indirect infections. Factors that cause the undesirable outcome of patient treatment. Purpose of use of protective medical supplies: prevent iatrogenic cross-infection, and have functionality, rationality and safety.
The types of non-woven fabrics used to make protective medical supplies mainly include functional non-woven materials such as spunlace non-woven fabrics, spunbonded non-woven fabrics, flash non-woven fabrics and polypropylene S M S composite materials. Among them, the spunlace and spunbond nonwovens are more comfortable to wear and use larger amounts. In particular, the spunlace non-woven fabric with natural cellulose pulp added has very good antibacterial properties and wearability.
For example, common face masks can effectively prevent cross-infection between the face and even the entire head of the medical staff and the patient, and have good air permeability, simple structure and comfortable use. It can prevent the mutual infection between doctors and patients through the air. The diameter of medical viruses and operating room dust is usually about 2μm. The virus usually parasitizes in dust above 0.5μm and enters the human body. "Spunlace non-woven fabrics or composite materials with meltblown non-woven fabrics in between are soft, breathable, and filterable. It has good performance and usually uses meltblown nonwovens with fiber diameters smaller than that of viruses and dust. Due to their small fiber diameters, the surface area of the fibers in the non-woven fabrics is increased, thereby ensuring excellent gas filtration and bacteria shielding functions.
