Description

A mattress for preventing pressure ulcers

technical field

The utility model belongs to the field of auxiliary medical treatment, in particular to a mattress for preventing pressure ulcers.

Background technique

Pressure ulcers, also known as pressure ulcers and bedsores, are tissue ulcers and necrosis caused by persistent ischemia, hypoxia, and malnutrition due to long-term pressure on local tissues. Skin pressure ulcers are a common problem in rehabilitation treatment and nursing. According to relevant literature reports, about 60,000 people die of pressure ulcer complications every year.

The main cause of pressure ulcers is sustained vertical pressure on local tissues, especially in the bony bulges of the body. If you stay in bed for a long time or sit in a wheelchair, improper placement of the inner liner of the splint, unevenness or debris in the plaster, or local pressure exceeding the normal capillary for a long time, pressure ulcers can be caused (generally, the blood vessels under the skin layer can withstand If the pressure exceeds the above pressure, the local blood vessels may be distorted and deformed, which will affect the passage of blood flow, and there will be ischemia).

At the same time, the skin is often subjected to physical stimuli such as moisture and friction (such as improper use of plaster bandages and splints, incontinence, uneven folds of sheets, debris on the bed, etc.), which reduces skin resistance and is also one of the reasons for pressure ulcers.

Utility model content

The purpose of the utility model is to provide a mattress for preventing pressure ulcers for long-term bedridden patients.

In order to achieve the above purpose, the present utility model adopts the following technical solutions: a mattress for preventing pressure ulcers, comprising: a support layer, an air cushion layer, an air pump and a controller; wherein the air cushion layer is located on the upper part of the support layer, and the air cushion layer includes a bottom layer Airbag, frame airbag and support airbag; the frame airbag is located around the bottom airbag, a cavity is formed in the middle, a plurality of support airbags are evenly arranged on the upper part of the bottom airbag, are located in the cavity, all the airbags are connected, and pass through the side of the bottom airbag The air inlet is connected to the air pump to inflate the air bag; the bottom of the supporting air bag is provided with a micro solenoid valve, and the solenoid valve is connected to an external controller through a circuit embedded in the air bag interlayer, and the controller controls the opening and closing of the electromagnetic valve in different areas. Close, control the inflation and deflation of the support airbags in different areas; the lower part of the frame airbag located on one side of the long end of the mattress is provided with a through hole, the outside of the through hole is connected to the air pump through the trachea, and the air pump is transported to the bottom of the cavity through the trachea and the through hole Air.

Further, the support airbag is in a circular or oval shape, the upper part of the airbag is made of elastic rubber material, and the lower part is made of hard plastic material.

Further, the bottom airbag and the frame airbag are made of hard plastic material.

Further, a control circuit and a battery pack are arranged inside the controller, and a control button is arranged outside.

Further, the support layer adopts brown pad or cotton pad.

When in use, cover a layer of sheet on the mattress, the patient lies on the sheet, adjust the opening of the air pump through the controller, part of the gas generated by the air pump enters the bottom air bag through the air inlet, and the air bag can be supported in different areas according to the patient's condition. The solenoid valve for inflation and deflation. Another part of the gas generated by the air pump is transported into the cavity through the trachea to the through hole of the frame air bag, so that there is air circulation between the mattress and the sheet.

The utility model has a novel structure and is convenient to use. The anti-pressure ulcer treatment mattress can adjust the amount of air in the supporting airbags of different parts through the micro solenoid valve, so as to relieve the continuous vertical pressure of the designated parts, thereby reducing the occurrence of pressure ulcers as much as possible. . In addition, there is a certain gap between the support airbags, and after the gas is blown from one side, there is a certain air flow between the support airbags, which is conducive to skin scabbing.
