Problems solved by technology

Compared with the traditional air cushion monitoring device based on the change of the electrical impedance value with the load, the device has better improvement, such as the monitoring accuracy, the ability to adapt to the environment and the ability to resist electromagnetic interference, but the optical fiber sensing link of the device is disconnected , the pollution of dust, liquid, etc. will cause a serious decline in its performance, and even cause the optical path to be blocked and lose the sensing function
These limit the scope of use of the device

Embodiment 1

[0041] Such as figure 1 , figure 2 , image 3 with Figure 4 The shown air cushion device includes an elastic plate and a plurality of airbags 2, the plurality of airbags 2 are connected with an air pump 6, the elastic plate is located on the upper surface of the plurality of airbags 2, and the elastic plate includes an upper surface plate 3 , the lower surface plate 4, a filler 35 is arranged between the upper surface plate 3 and the lower surface plate 4, and a plurality of curved brackets are arranged in the filler 35, and the inside of the curved bracket is arranged on opposite sides There are multiple A-side deformed teeth 4-1 and multiple B-side deformed teeth 4-2, and the multiple A-side deformed teeth 4-1 and multiple B-side deformed teeth 4-2 are arranged in a staggered manner, and the heads of the two A curved passage for one or more signal optical fibers 33 is formed between the parts, and the A-side deformed teeth 4-1 and the B-side deformed teeth 4-2 are corre...

Embodiment 2

[0049] Such as Figure 4 , Figure 5 As shown, in this embodiment, the difference from Embodiment 1 is that the curved support is a spring 38, and the deformation teeth 4-1 on the A side and the deformation teeth 4-2 on the B side are arranged adjacent to each other in the spring 38. Between the two coils of spring wire, the deformation teeth 4-1 on the A side and the deformation teeth 4-2 on the B side are alternately arranged. In this embodiment, the structures, connections and working principles of other parts are the same as those in Embodiment 1.

Embodiment 3

[0051] Such as Image 6 , Figure 7 As shown, in this embodiment, the difference from Embodiment 1 is that the curved bracket is a bellows 40, and the deformation teeth 4-1 on the A side and the deformation teeth 4-2 on the B side are correspondingly arranged on the pipe wall of the bellows 40 On the two opposite side surfaces of the inner recess on 41, the A-side deformed teeth 4-1 and the B-side deformed teeth 4-2 are alternately arranged. In this embodiment, the structures, connections and working principles of other parts are the same as those in Embodiment 1.

Abstract

The invention discloses an air cushion device. The device comprises: an elastic plate and a plurality of air bags, wherein the air bags are connected with a pump, the elastic plate which is positioned on upper surfaces of the air bags comprises an upper surface plate and a lower surface plate, a filler is arranged between the upper surface plate and the lower surface plate, a curve-shaped support is arranged in the filler, A-side deformed teeth and B-side deformed teeth are distributed on two opposite sides in the curve-shaped support, curve-shaped channels for one or more of signal optical fibers to traverse through are formed between heads of the A-side deformed teeth and the B-side deformed teeth, and the A-side deformed teeth and B-side deformed teeth are correspondingly distributed on two sides of the signal optical fiber; and a signal optical fiber connection testing unit and a testing unit connection processing unit, wherein the processing unit adjusts the amount of the gas filled in each air bag by controlling the air pump according to the elastic plate pressure distribution detected by the testing unit. The device of the invention has the advantages of simple structure, reasonable design, low cost, flexible use mode, high sensitivity, and good use effect.

Description

technical field [0001] The invention relates to an air cushion device. Background technique [0002] People who lie down in one posture for a long time will make the parts of the human body that bear more weight uncomfortable. Normal people can change the position to replace the parts that bear more weight. However, some old people and patients can only use the help of nurses Turn over or change the body posture, but in many cases, the caregiver does not know which parts need to adjust the pressure and which parts do not need to be changed, which leads to bedsores on the skin surface of some patients or the care recipients, which is life-threatening in severe cases. [0003] Chinese patent 200680041502.2 discloses an air cushion device, which uses an elastic plate with an optical fiber sensing device placed on the surface of the air cushion to monitor the pressure, and then adjusts the inflation amount of the airbag in the air cushion accordingly to achieve the purpose of au...
