Wound filling dressing for closed negative pressure drainage of surgical wound as well as preparation method

Abstract

The invention relates to a wound filling dressing for the closed negative pressure drainage of a surgical wound as well as a preparation method. The wound filling dressing mainly comprises a vegetable sponge matrix, micropore fabrics, a semi-transparent film and a negative pressure drainage duct, wherein the vegetable sponge matrix is matched with the wound in the shape, the micropore fabrics arerespectively arranged on the upper surface and the lower surface of the vegetable sponge matrix or wrapped on the surface of the vegetable sponge matrix, the semi-transparent film covers the upper surface of the vegetable sponge matrix to take the closing and fixing action, and the negative pressure drainage duct is inserted in the vegetable sponge matrix. The invention has low cost, simple structure, convenience of manufacture and low raw material and manufacture costs being only about one percent of a similar product, and can greatly decrease the medical cost and accordingly be favorable tothe popularization of a closed negative pressure suction technology.

Description

Technical field [0001] The invention relates to a medical article and a preparation method, in particular to a wound filling dressing used in a surgical closed negative pressure drainage device, specifically a low-cost loofah tendon instead of high-cost porous sponge as the wound surface Wound filling dressing for closed negative pressure drainage of surgical wound with filtering suction head and preparation method thereof. Background technique [0002] Vacuum-assisted Closure (VAC) is the cutting-edge technology of wound treatment in the 21st century. It has revolutionized wound treatment and is widely used in various acute or chronic wounds and ulcers on the body surface, and large areas of soft tissue Coverage and drainage of wounds under conditions such as defects, tissue defects or exposed organs caused by war trauma. [0003] Traditional treatment methods are difficult for complex injuries caused by heavy damage, heavy pollution, multiple tissues, and multiple injury factor...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to solve the problem that the cost of filling dressings in contact with the wound surface used in the existing closed negative pressure drainage technology is very high, and to invent a surgical wound closure based on a low-cost pure natural material based on loofah tendons Wound filling dressing for type negative pressure drainage, and the preparation method of this wound filling dressing is provided at the same time
