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

[0033] like figure 1 As shown, a wound dressing based on liquid material for oxygen supply is characterized in that: the dressing is composed of a dressing unit, and the dressing unit is divided into two parts: the first part is mainly composed of a waterproof membrane 101 from top to bottom, a hydrogen peroxide storage container 102, and a protective The waterproof membrane 101 is composed of a membrane 103, and the waterproof membrane 101 is located on the outermost layer to achieve a sealing effect when the dressing sticks to the skin. The waterproof membrane 101 can be made of polyethylene, which can prevent dust, water, air leakage and pollution. The container wall of the hydrogen peroxide storage container 102 towards the wound side is provided with a small hole 4, hydrogen peroxide is stored in the hydrogen peroxide storage container 102, and the hydrogen peroxide concentration is 3% hydrogen peroxide, i.e. medical hydrogen peroxide. During the use of the dressing, the ...

Embodiment 2

[0048] like figure 1 and 2 As shown, the difference between this embodiment and Embodiment 1 is that the container wall of the hydrogen peroxide storage container 102 facing the wound is provided with a small hole 4 with a larger aperture, and a layer of permeable water is adhered to the outer surface of the small hole 4. Membrane 401 allows hydrogen peroxide to seep out at a certain rate, and generates oxygen after contacting the catalyst. The advantage of this design is that hydrogen peroxide can continuously permeate and generate oxygen, which can maintain the amount of oxygen on the wound surface and avoid failure due to leakage. The permeable membrane 401 can be made of polyamide, polyimide, polyethersulfone, etc. During storage and transportation, since the protective film 103 is pasted on the surface, the liquid will not leak.

[0049] The preparation method of hydrogen peroxide reservoir 102 in this embodiment comprises the steps:

[0050] 1) The container wall of t...

Embodiment 3

[0055] like Figure 3-5 As shown, the difference between this embodiment and Embodiment 1 is that the dressing includes at least one dressing unit, such as Figure 3-5 As shown, a plurality of dressing units can be arranged and combined. When used for small wounds, the dressing area is small, and a single dressing unit can be used; when used for large wounds, the dressing area is large, and if cutting is required, it can be designed as a combination of multiple dressing units. The advantage of this design is that it can be used It can be cut according to the size of the wound; it is beneficial for the reagent to be evenly distributed on the surface of the dressing, so as to prevent the phenomenon that the liquid flows to one side due to the position and angle during use.

Abstract

The invention discloses wound oxygen supply dressing based on a liquid material and a production method thereof. The wound oxygen supply dressing is characterized by being prepared from a dressing unit which is divided into two parts: the first part is primarily comprised by a waterproof film, a hydrogen peroxide storage container and a protecting film successively from top to bottom, small holesare formed in the container wall, toward one side of the wound, of the hydrogen peroxide storage container, and the hydrogen peroxide storage container stores hydrogen peroxide; and the second part issuccessively composed of a protecting layer a, a medicine bag, a water suction pad and a protecting layer b from top to bottom, and the medicine bag comprises a catalyst; the hydrogen peroxide seeping from the hydrogen peroxide storage container is in contact with the catalyst. The wound oxygen supply dressing provided by the invention can provide an oxygen-enriching environment to the wound to accelerate the healing process of the wound and alleviate pain of the patient, and scars are repaired favorably, the wound is attractive.

Description

technical field [0001] The present invention relates to a medical hygiene article, more specifically, to a wound dressing based on liquid material for 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 h...
