Problems solved by technology

[0003] Although traditional dressings can protect the wound and promote wound healing to varying degrees, the healing effect is often poor because the wound is in a state of hypoxia during the healing process

Embodiment

[0030] Such as figure 1 As shown, a dressing based on a composite film structure (sheet) composed of various polymer materials generates oxygen to supply oxygen to the wound. The first part is mainly composed of an anti-leakage protective film (1) from top to bottom, and a water-absorbing pad ( 2), the second part consists of an anti-leakage protective film (3), a water-absorbing pad (4), an oxygen supply film (sheet) (5), an air-permeable and water-impermeable film (6) and a wound protection layer ( 7) Composition; the anti-leakage protective film (1) and the anti-leakage protective film (3) are coated with medical glue, and the anti-leakage protective film (3) is glued for sticking to the skin to realize a fixed dressing, preventing The air leakage protection film (1) is glued and pasted on the air leakage prevention protection film (3), fixed and airtight, and has the effects of dustproof, waterproof, air leakage prevention and pollution prevention.

Abstract

The invention discloses a dressing, which can produce oxygen through chemical reactions of a composite membrane (sheet) based on various high-molecular materials or composed by using the materials ascarriers, and which can, therefore, supply oxygen to a wound at uniform speed, and a production technique of the dressing. The dressing comprises: a first portion mainly composed of an anti-air-leaking protective membrane and a water-sucking storage pad sequentially form top to bottom; and a second portion composed of an anti-air-leaking protective membrane, a water-sucking storage pad, an oxygensupply membrane (sheet), a breathable watertight membrane and a wound protective layer; the oxygen supply membrane (sheet) contains an oxidant (such as a peroxide). The invention relates to the dressing for wound oxygen supply, which can provide an oxygen-rich environment for a wound to accelerate wound healing and kill anaerobic bacteria.

Description

technical field [0001] The present invention relates to a medical product, more specifically, to a dressing based on a variety of polymer materials or a composite film structure (sheet) composed of such polymer materials as a carrier to generate oxygen to supply oxygen to wounds and its production process. Background technique [0002] When people are injured, they use wound dressings for wound care. As we all know, oxygen plays an important role in the wound healing process and can control the growth and spread of bacteria; at the same time, the lack of oxygen caused by the destruction of capillaries around the wound is not conducive to cell regeneration; external oxygen supply is conducive to cell regeneration and thus accelerates the wound of healing. None of the current traditional wound dressings can achieve this effect. According to its materials and functions, it can be divided into the following three types: 1. Inert dressing: it has the advantages of protecting th...
