Background
One of the key reasons for the difficulty in healing wounds, especially chronic wounds, is hypoxia in the internal environment of tissues, hypoxia in local interstitial fluid and hypoxia in local cells, and the wound surface slowly adapts to the hypoxia environment, is in a strange equilibrium state but cannot be repaired, so that great trouble is brought to patients. The factors of wound hypoxia are many. Including, 1, increased oxygen consumption of the wound, infection, etc.; 2. the negative pressure drainage can also reduce the tissue oxygenation of the most ischemia sensitive area of the body, so as to cause the hypoxia of the wound surface; 3. covering the dressing may also further exacerbate hypoxia of the wound; 4. the moist environment of the wound, retaining moisture in the dressing may also inadvertently reduce the supply of oxygen in the air above the wound bed.
In clinical practice, most medical personnel usually treat wounds with covering dressings after the patients are injured, and it is well known that oxygen plays an important role in the healing process of wounds: can control the growth and diffusion of bacteria; is beneficial to the regeneration of blood vessels; promoting the formation of collagen.
Conventional wound dressings at present comprise, in terms of the materials and functions used: the inert dressing is generally processed by cotton, linen and linen, has no obvious effect on healing of the wound surface, but has the advantages of wound surface protection, absorbability, simple manufacture and low price; also included are dual-purpose dressings: the dressing can promote wound healing by using the local environment caused by the dressing, and has stronger absorption function. For example, an absorbent film made of a polyurethane material, or a three-dimensional network water-absorbent polymer composed of gelatin, polysaccharide, a multi-dielectric composite and methacrylic resin, or a porous foam composed of polyurethane and polyoxyethylene glycol; although the traditional dressing can protect the wound and promote the wound healing to different degrees, the healing effect is often poor because the wound is in an anoxic state in the healing process.
The Chinese patent application: : CN102225224B discloses a vacuum oxygen supply device for maintaining a wound in a negative pressure state and supplying oxygen to the wound, which comprises a wound covering component, an oxygen delivery pipe, a vacuum fluid pumping pipe, a first vacuum pump, a collecting bottle and an oxygen machine, wherein two ends of the oxygen delivery pipe are respectively in fluid communication with the wound covering component and the oxygen machine, two ends of the vacuum fluid pumping pipe are respectively in fluid communication with the wound covering component and the collecting bottle, and the first vacuum pump is disposed on the vacuum fluid pumping pipe between the wound covering component and the collecting bottle. The device can effectively prevent the air drying and chapping of the new skin and flesh caused by over-drying of the wound, and can ensure that the wound can obtain sufficient oxygen and nutrient substances to promote the wound to heal as soon as possible. However, the device also has an oxygen machine or a central oxygen supply system of a hospital to be connected with an oxygen therapy tube or an oxygen mask device to deliver oxygen, so that the whole activity area of a patient is limited, the portability is poor, and the continuous oxygen therapy of the patient is difficult to ensure.
In view of the above, there is a need for an oxygen therapy dressing that is simple in structure, convenient to operate, and portable, and can be used to treat wounds instead of conventional covering dressings, provide oxygen therapy effects, and promote wound healing, but no report is found about such a portable oxygen generation device for wound oxygen therapy.

The working principle of the invention is as follows: by utilizing chemical reaction, hydrogen peroxide is injected into the oxygen therapy dressing body with manganese dioxide, and the hydrogen peroxide generates oxygen and water under the catalysis of the manganese dioxide. According to the chemical reaction equation 2h2o2=2h2o + o2, about 68g of hydrogen peroxide to generate about 32g of oxygen and 36g of water can be estimated, and the density of hydrogen peroxide is as follows: 1.13g/mL (20 ℃), which is calculated from the formula V = Vm × n to have an oxygen volume of 716.8mL, 1 mL containing 1 g per 1 g of oxygen at almost normal temperature, and 10 mL per 1 g. For a common wound, 5 ml of hydrogen peroxide is injected each time to generate 50 ml of oxygen, and the rest is done according to the wound condition of a patient.
In the embodiment, the shape of the oxygen therapy application body 1 can be determined according to different shapes of limb parts, so that the use requirements of different wound shapes of different patients are met, and the use convenience and comfort are improved.
In this embodiment, the outer end of the oxygen therapy dressing body 1 is preferably a semi-closed cover body, for example, a semi-closed structure can be made by non-woven fabrics, CPE, plastic, etc., so as to increase the oxygen concentration in a local area; and semi-closed oxygen therapy is applied ointment or plaster the body and can cooperate the elastic sealing strip to provide a relative semi-enclosed space around the wound, and the layer is makeed for semi-enclosed space through the oxygen and is carried oxygen, forms high concentration oxygen around the wound to promote wound healing.
The use method of the invention comprises the following steps: when in use, the oxygen therapy application is fixed at the wound of a patient through the fixing band, and the tightness is adjusted through the direct contact area of the hair side magic tape and the thorn side magic tape, so as to improve the wearing comfort of the patient; then, a small amount of hydrogen peroxide is dripped into the one-way valve, and the hydrogen peroxide reacts with manganese dioxide in the first oxygen generation layer after being dripped to generate water and oxygen (assuming that the injected hydrogen peroxide is more and is not completely decomposed, the reaction can be carried out by arranging the next oxygen generation layer); the generated water and oxygen can flow into the second moisture absorption layer, the flowed water is absorbed by the second moisture absorption layer, and the rest oxygen can flow into the third oxygen release layer and then acts on the wound of the patient through the oxygen release layer, so that the oxygen therapy effect on the wound is realized.
It should be noted that: the chemical oxygen generation method solves the problems that the traditional covering dressing has poor wound treatment effect and the oxygen therapy machine limits the movement of a patient, and the chemical oxygen generation space is arranged in the oxygen therapy application body and forms a relative semi-closed space around the wound by matching with the oxygen therapy application body and the elastic sealing strip, so that oxygen is delivered to the semi-closed space, high-concentration oxygen is formed around the wound, and the wound healing is promoted. The oxygen-enriched wound oxygen absorption device is simple in overall structure, convenient to operate and carry, provides an oxygen-enriched environment for the wound of a patient, enables the wound to be effectively subjected to oxygen absorption, and is beneficial to wound healing of the patient.
