Embodiment 1

[0024] Such as figure 1 As shown, a wound dressing based on gas oxygen supply is composed of a waterproof membrane 1, a gas storage container 2, an absorbent pad 3 and a protective membrane from top to bottom. The gas storage container 2 contains high-concentration oxygen at a certain pressure, which can provide an oxygen-enriched environment for the wound, which is beneficial to accelerate the wound healing process; relieve pain of the patient; and is beneficial to repair scars and make the wound beautiful. The container wall of gas storage container 2 is provided with aperture 21, as figure 2 As shown, the small hole 21 is covered with a water-dissolvable material 201, and the water-dissolvable material can be gelatin, PVA, CMC, HEC, HPMC, starch film, etc., or any combination thereof. Materials that can dissolve in water dissolve when contacting wound secretions, so that the oxygen in the gas storage container 2 is released to the surface of the wound, providing an oxygen...

Embodiment 2

[0031] Such as figure 1 with 3 As shown, the difference between this embodiment and Embodiment 1 is that a small hole 21 is arranged on the container wall of the gas storage container 2, and the small hole 21 is covered with a gas-permeable film 202, and oxygen is slowly released through the gas-permeable film 202, which can Continuous oxygen supply to the wound.

[0032] The preparation method of the dressing comprises the following steps: 1) pre-processing the small hole 21 on the container wall of the gas storage container 2, and covering it with a gas-permeable film 202; the waterproof film 1 and the protective film of the dressing are well sealed.

Embodiment 3

[0034] Such as figure 1 with 4 As shown, the difference between this embodiment and Embodiment 1 is that the container wall of the gas storage container 2 is provided with a small hole 21, and the small hole 21 is covered with a material 201 that can dissolve in water and a gas-permeable film 202. The water-soluble material 201 covers the outside of the gas-permeable membrane 202 . In use, the water-soluble material 201 dissolves when it contacts wound secretions, and oxygen is released to the wound through the gas-permeable membrane 202 .

[0035] The method for preparing the gas storage container 2 comprises the following steps:

[0036] A small hole 21 is pre-processed on the container wall of the gas storage container 2, and covered with a gas-permeable film 202, and the outer surface of the gas-permeable film 202 is covered with a material 201 that can dissolve in water.

Abstract

The invention discloses a wound dressing based on gas oxygen supply and a production method of the wound dressing. The wound dressing is characterized in that the wound dressing sequentially and mainly comprises a waterproof film, a gas storage container, a water absorption mat and a protection film from top to bottom, small holes are formed in the wall of the gas storage container, materials and / or ventilation films cover the small holes, the materials can be dissolved when touching water, and oxygen with pressure is stored in the gas storage container. According to the wound oxygen supply dressing, oxygen-enriched environments can be provided for wounds, wound healing is accelerated, patient pain is relieved, and scar repair is facilitated, so that the wounds are beautiful.

Description

technical field [0001] The present invention relates to a medical hygiene article, more specifically, to a wound dressing based on gas oxygen supply and a production method thereof. 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: it can control the growth and spread of bacteria; it is beneficial to the regeneration of blood vessels; and it can promote the formation of collagen. At present, traditional wound dressings can be divided into the following three types according to their materials and functions: 1. Inert dressings: generally processed from cotton, soft linen and linen, which have no obvious effect on wound healing, but have the functions of protecting wounds, Absorbability, simple production and cheap price; 2. Dual-action dressing: This type of dressing can use the local environment it creates to promote wound healing, and has a strong abso...
