However, there are some shortcomings in the existing dressings: when there is too much exudate, the water-absorbing layer cannot completely absorb it, and it will seep again from the water-absorbing layer, causing the skin at the wound to be soaked and softened, the healing speed is slow, and even ulceration occurs , greatly increasing the pain of the injured

Abstract

The invention relates to a medical dressing, specifically a novel foam composite wound dressing, comprising a water-absorbing layer and a water-locking layer covered above the water-absorbing layer, a transition layer is arranged between the water-absorbing layer and the water-locking layer, and a water-locking layer is placed above the water-locking layer Covered with a waterproof layer with a polyurethane membrane layer underneath the absorbent layer. The invention is non-toxic and non-irritating to the human body. The water-absorbing layer quickly absorbs the water around the wound, and the water-locking layer absorbs and locks the water to prevent the backflow of water, ensure the appropriate temperature and humidity at the wound, and prevent the skin from appearing on the application site. Impregnated reaction, fast wound healing; using silicone gel to stick and fix the effect is good, it is not easy to fall off, and it will not cause strain on the skin.

Description

technical field [0001] The invention relates to a medical dressing, in particular to a novel foam composite wound dressing. Background technique [0002] Wounds after injury or surgery need to be treated with wound dressings to absorb excess exudate exudate from the wound and allow the wound to heal quickly. However, the existing dressings have some shortcomings: when there is too much exudate, the water-absorbing layer cannot completely absorb it, and it will seep again from the water-absorbing layer, causing the skin at the wound to be soaked and softened, the healing speed is slow, and even ulceration occurs , greatly increasing the pain of the injured. Contents of the invention [0003] In order to solve the above-mentioned deficiencies in the prior art, the present invention provides a novel foam composite wound dressing, which can ensure proper temperature and humidity at the wound, fast wound healing, improve treatment efficiency, and reduce the pain of the wounded...
