Abstract

The invention relates to a medical dressing, in particular to a novel foam composite wound dressing. The novel foam composite wound dressing includes a water absorbing layer and a water locking layer arranged above the water absorbing layer in a covering manner, wherein a transitional layer is arranged between the water absorbing layer and the water locking layer, a waterproof layer is arranged above the water locking layer in a covering manner, and a polyurethane film layer is arranged below the water absorbing layer. The novel foam composite wound dressing is neither toxic nor irritating to human bodies; moisture around a wound can be quickly absorbed through the water absorbing layer, and absorbed and locked through the water locking layer, which prevents the moisture backflow, guarantees a suitable temperature and a suitable humidity of the wound, prevents the soaking reaction of the skin at the application position, and achieves rapid healing of the wound; the application through silica gel achieves good fixation effect and low falling possibility, and avoids the skin injury by pulling.

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...
