Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] Such as figure 1 shown.

[0031] A wound filling dressing for closed negative pressure drainage of surgical wounds, which is mainly composed of loofah tendon matrix 1, microporous fabric bottom layer 2, microporous fabric surface layer 3, semipermeable membrane 4 and suction tube 5, the loofah tendon matrix 1 The thickness can be controlled within 4 cm. It is located between the bottom layer 2 and the surface layer 3 of the microporous fabric. The bottom layer 2 and the surface layer 3 of the microporous fabric can be connected to form a bag-like structure or not connected to each other. 4 is a material that is permeable to gas but impermeable to water. Its main function is to form a closed environment on the surface of the wound, so that negative pressure can be formed through the negative pressure generator in the closed environment, thereby f...

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 are respectively 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 to the popularization of a closed negative pressure suction technology.

Description

technical field [0001] The invention relates to a medical product and a preparation method, in particular to a wound filling dressing used in a surgical closed negative pressure drainage device, specifically a kind of wound surface that uses cheap loofah tendon instead of expensive porous sponge A wound filling dressing for closed negative pressure drainage of a surgical wound with a filter suction head and a preparation method thereof. Background technique [0002] Vacuum-assisted closure technology (VAC) is the cutting-edge technology of wound treatment in the 21st century, which has revolutionized wound treatment and is widely used in various acute or chronic wounds and ulcers on the body surface, as well as large areas of soft tissue Wound coverage and drainage in the event of defect, tissue defect caused by war trauma, or exposed organs. [0003] Traditional treatment methods are more difficult for complex injuries caused by heavy damage, heavy pollution, involving mu...
