Description

A skin pressure adjustment and control method for anti-decubitus mattresses

Technical field

The present invention relates to the technical field of bedsore prevention and treatment, and in particular to a skin pressure adjustment and control method for a bedsore prevention mattress.

Background technique

The local tissues of bedridden patients are prone to blood flow obstruction due to continuous pressure or shear force, which leads to tissue ischemia, triggers local inflammatory reaction, and even invasion of external pathogenic bacteria to cause local infection, causing tissue necrosis and causing bedsores.

Avoiding excessive local pressure on the patient's skin is one of the important means to prevent and treat bedsores. Therefore, it is very necessary to monitor and adjust the skin pressure of bedridden patients.

For example, Chinese invention patent CN114209303A discloses a human body pressure monitoring and adaptive adjustment system, including an air bag array, a flexible array pressure sensor, an air pump, a lower computer electrical module and a host computer module. The flexible array pressure sensor is arranged above the air bag array and connected to the air bag array. The electrical module of the lower machine is connected; the air bag array includes a fixed shell and an air bag body. Multiple air bag bodies are arranged in a matrix and installed in the fixed shell. The inlet of each air bag body is connected to the air pump; the air pump is connected to the electrical module of the lower machine. The pressure of the disabled elderly person is collected through the flexible array pressure sensor and transmitted to the upper computer module through the electrical module of the lower computer. When the upper computer module detects that the pressure is within a certain range for a long time, the signal is fed back to the electrical module of the lower computer. The electrical module of the lower computer The module controls the inflation and deflation of the airbag body so that the human body pressure reaches the expected value.

When the above-mentioned human body pressure monitoring and adaptive adjustment system is specifically adjusted, the airbag body needs to be manually inflated and deflated to the most comfortable state according to the feelings of different individuals, and the data of each point of the flexible array pressure sensor at this time is recorded. , find the average value p, and use it as a reference value for the air bag inflation and deflation adjustment.

However, due to the difference in weight of various parts of the human body, when a bedridden patient lies on the bed, different parts of the human body exert different pressures on the mattress. However, the existing technology uses an average value p as a reference and cannot achieve the same goal for all parts of the human body. Optimal stress state.

As shown in Figures 1-4, embodiments of the present invention provide a skin pressure adjustment and control method for an anti-decubitus mattress.

The anti-decubitus mattress includes a mattress body 100, an inflation and deflation device 200, and a control host (not shown in the figure). The mattress body 100 includes a support plate 110, a plurality of airbags 120 arrayed on the support plate 110, and a On the upper cushion body 130 of each air bag 120, the bottom of the upper cushion body 130 is provided with a plurality of pressure sensors 131 corresponding to each air bag 120. The output end of the inflation and deflation device 200 is connected to a main pipe 210, and each air bag 120 Both are provided with inflation and deflation ports 1211. The inflation and deflation ports 1211 of each air bag 120 are respectively connected to the main pipe 210 through a corresponding solenoid valve 220. The input end of the control host is electrically connected to each pressure sensor 131, and the output end of the control host is electrically connected to the charging port. The air release device 200 and each solenoid valve 220 are electrically connected.

The skin pressure regulation control method includes the following steps:

Step S10: Obtain the pressure data of the pressure sensor 131 at each point when the patient lies on the anti-decubitus mattress.

Step S20: Based on the pressure distribution at each point, determine the areas corresponding to each part of the human body when the patient lies on the anti-decubitus mattress.

As a specific example, referring to Figure 4, each region includes a head region 310 that bears pressure on the human head, a waist region 320 that bears pressure on the human waist, and a hip region 330 that bears pressure on the human hip. , the upper limb area 340 that bears pressure on the upper limbs of the human body, and the lower limb area 350 that bears pressure on the lower limbs of the human body.

In step S30, the pressure of each area is adjusted respectively. When the pressure of a certain area is adjusted, the control host outputs a signal to control each solenoid valve 220 in this area to open at the same time, and the solenoid valves 220 in other areas are kept closed, and then the charging and discharging are controlled. The air device 200 inflates or deflates each air bag 120 in the local area so that the pressure values at each point in the local area are equal or close.
