Anti-pressure sore automatic inflation decompression ring structure

This creation relates to a decompression ring structure, in particular to an automatic pneumatic decompression ring structure for an anti-pressure sore.

Press pressure; commonly known as acne, pressure sore is because the skin is under pressure (or oppression), the skin caused by friction and even deep into the subcutaneous tissue, muscles and bones is called pressure sores.

Pressure sores are common medical problems in patients with long-term physical activity (including those with spinal cord injury), prolonged bed rest, unconsciousness, incontinence, diabetes or skin weakness, physical weakness, or malnutrition. Pressure sores often occur in the elbow, heel, buttocks sacrum, the posterior occipital bone, and so on.

The causes of pressure sores are as follows:

1. There is no time to turn over for the patient.

2. The method of restraining the patient and positioning is incorrect.

3. There is no time to change the diaper for the patient.

4. The patient is afraid of pain or unwilling to cooperate.

5. The patient has diabetes or a blood disease (such as anemia) malnutrition, skin fragility or sensitivity.

6. The patient is subjected to undue compression or friction for a long time.

7. The patient has oozing or long-term diarrhea, which is relatively fragile around the anus.

The cause of the pressure sore wound is that the local skin and the soft tissue under it are pressed for a long time, causing the cells to be hypoxic and necrotic. The treatment of pressure sore wounds is very troublesome. The small ones delay healing for several weeks, while the others suffer from sepsis, amputation or death. Not only does the injury cause medical burden and waste.

A conventional air bed product that reduces the chance of pressure sore for people who are in bed for a long time or who are in a wheelchair for a long time. Because the pressure sore is difficult to heal once it is formed, the air bed is designed to reduce the damage caused by prolonged compression or friction of the skin or subcutaneous tissue in a person who has been in bed for a long time or who must be in a wheelchair for a long time.

The conventional air bed is divided into a static type and an alternate type according to a gas flow mode. The static type is the purpose of achieving the pressure equalization by the principle of the communication tube, and the alternating type is to avoid the excessive pressure of the same skin for a long time by switching the gas pressure, thereby achieving the effect of preventing pressure sore.

However, the practical use of the air bed in the conventional use will cause problems and lack of large area, complicated structure, inconvenient operation, and not being able to be placed in a specific part of the human body, and it is necessary to improve it in an ideal state.

Therefore, based on the concept of continuous research and innovation of products and the experience of product design and development for many years, the creator is actively researching and thinking, and has produced this creation through numerous practical design experiments.

The purpose of the present invention is to provide an automatic inflation and decompression of anti-pressure sores which are formed by various types of loops which can be flexibly adjusted by the airbag device to be placed on a predetermined part of the human body and which cause high and low changes between the airbags. Circle structure.

For the above purposes, the present invention comprises an airbag device and a control device, wherein the airbag device has an elongated shape, and the airbag device comprises a covering body selected from a flexible material, the outer covering surface Having a plurality of joints, wherein the two joints can be combined and separated, the cover body has a plurality of air pipes, the air pipe is provided with a plurality of air bags; the control device comprises a plurality of inflatable components, a plurality of air release components, and a control circuit The air-inflating element and the air-discharging element are connected to the air pipe, and the control circuit is electrically connected to the air-inflating element and the air-dissipating element for controlling the air-inflating element, and the air-discharging element inflates and deflates the air bag via the air pipe.

The airbag device is formed into a structure that can be flexibly adjusted so as to form a ring of various sizes and fixed, which is beneficial to a predetermined part of the human body such as an elbow, a heel, a hip sac, a posterior occipital bone, and the like. The airbag is automatically inflated and deflated by the control device to cause high and low changes between the airbags, thereby reducing the damage caused by compression or friction of the same skin or subcutaneous tissue for a long time, thereby achieving the effect of preventing pressure sores.

This creation solves the problems and disadvantages of the large size of the conventional air bed, the complicated structure, the inconvenient operation, and the inability to be placed on a specific part of the human body.
