Description

A kind of portable oxygen generator oxygen supply method and material for wound healing

technical field

The present invention relates to a medical product, more particularly, a method and material for a portable oxygen generator to supply oxygen for wound healing, and to supply oxygen to the wound and keep the wound site and the oxygen outlet of the oxygen generator sealed in an auxiliary material to keep pure Oxygen state, while applying a patch containing an oxygen carrier to the wound to achieve a device and consumable to increase the concentration and solubility of oxygen molecules in the wound.

Background technique

When people are injured, they use wound dressings for wound care. It is well known that oxygen plays an important role in the healing process of wounds. It 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 accelerates wound healing. At present, traditional methods of wound treatment cannot achieve this effect. According to the materials and functions they use, they can be divided into the following three types: 1. Inert dressings: they have the advantages of protecting the wound surface, being absorbent, easy to make and cheap; 2. Dual-action dressings: these dressings can use the The local environment promotes wound healing and has a strong absorption function. For example, an absorbent film made of polyurethane material, or a three-dimensional network water-absorbing polymer composed of gelatin, polysaccharide, multi-dielectric complex and methacrylic resin, or a Oxyethylene glycol porous foam composition. 3. Bioactive dressing: a combined dressing made of polymer materials and biological materials by high-tech methods, has a double-layer structure, and the outer layer is made of polymer materials, providing a barrier function equivalent to the epidermis; the inner layer is selected The main materials are collagen, chitosan and calcium alginate, which have biocompatibility, good water absorption, air permeability, adhesion and antibacterial and hemostatic effects.

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.

There are also local equipment oxygen supply methods, but the local oxygen pressure cannot be formed, or the oxygen pressure can be formed but the oxygen partial pressure cannot be increased.

Therefore, there is an urgent need for a method capable of autonomous oxygen supply, which can be combined with equipment to provide an oxygen-rich environment for the wound, reduce the slow healing of cells due to hypoxia after the capillaries are destroyed, and relieve the pain of the patient.
