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 1

[0025] Such as figure 1 As shown, a kind of polymer material is a dressing for wound oxygen supply composed of multiple films of the carrier. It is characterized in that the dressing is divided into two parts, and the first part is mainly composed of an anti-leakage protective film ( 1), composed of water-containing polymer gel (2), protective film (3), and protective layer (4). The second part is the protective layer (5), the calcium peroxide controlled release structure (6), the air-permeable and water-impermeable membrane (7) and the structure of perfluoronaline gel preparation (perfluorocarbon emulsion gel preparation or products with similar functions) ) or absorbent pads or other structures such as sodium alginate (8).

[0026] The upper part of the anti-leakage protective film (1) is coated with medical adhesive glue, which is used to stick to the second part to realize the function of fixing the first part. Waterproof, anti-leakage, anti-pollution effect.

Abstract

The invention discloses a wound oxygen-supply dressing composed of a polymer material as a carrier and a variety of films through a chemical reaction to generate oxygen so as to supply oxygen to the wound at a uniform speed and its production process. The dressing is characterized in that: the dressing is divided into two parts: The first part is mainly composed of an anti-leakage protective film, a polymer gel containing water, a protective film, and a protective layer from top to bottom. The second part is composed of a protective layer, a calcium peroxide controlled-release film, a breathable and water-impermeable film, and a perfluoronaline gel preparation structure (perfluorocarbon emulsion gel preparation or products with similar functions). Oxygen dressing can provide an oxygen-rich environment for the wound, accelerate wound healing, and kill anaerobic bacteria.

Description

technical field [0001] The invention relates to a medical product, and more specifically, to a dressing and a production process thereof, which are composed of multiple films based on a polymer material as a carrier and generate oxygen to supply oxygen to a wound. 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, which can control the growth and spread of bacteria. At the same time, due to the destruction of capillaries around the wound, the hypoxia of cells is not conducive to cell regeneration, while external oxygen supply is conducive to cell regeneration and thus accelerates. wound 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 the wound surface, absorbing, simple to ma...
