Referring to FIG. 1 , an embodiment of the present invention provides a pressure sensing inflatable cushion 100 including a gasket 10 , a pressure sensor 20 , a temperature sensor 30 , a controller 40 , an inflator 50 , and a warning device 60 . Referring to FIG. 2 , the spacer 10 includes a central region 110 , an edge region 120 , and an adjustment region 130 . The adjustment region 130 is located between the edge regions 120 and distributed around the central region 110 . The gasket 10 includes a plurality of air cells 131 and a plurality of valves 132 in the adjustment area 130. The air bags 131 are aligned with the number of valves 132, and each valve 132 is used to control the charge and discharge of one air bag 131.

The working principle of the pressure sensing inflatable cushion 100 is specifically as follows: The gasket 10 has a supporting function and is subjected to pressure when supporting a human body or other objects having a weight. The pressure sensor 20 is received in the gasket 10 and is capable of sensing the magnitude and distribution of the pressure experienced by the gasket 10 when the gasket 10 is under pressure.

The temperature sensor 30 is housed in the gasket 10 and connected to the pressure sensor 20, and the temperature sensor 30 can determine whether the pressure applied to the gasket 10 is derived from the human body. It can be understood that the temperature sensor 30 determines whether the pressure received by the gasket 10 is derived from the human body based on whether the detected temperature value falls within the range of the normal human body temperature value. In a practical application, the temperature sensor 30 starts to determine whether the pressure received is from the human body when the pressure sensor 20 senses that the gasket 10 is under pressure.

The controller 40 is connected to the pressure sensor 20 and the temperature sensor 30 respectively, and the controller 40 can analyze the posture of the human body according to the magnitude and distribution of the pressure sensed by the pressure sensor 20. It can be understood that the posture of the human body can be reflected by the size and shape of the contact surface of the human body and the gasket 10, and the size and shape of the contact surface can be known by the magnitude and distribution of the pressure sensed by the pressure sensor 20. In a practical application, the controller 40 analyzes the posture of the human body according to the magnitude and distribution of the pressure sensed by the pressure sensor 20 when the temperature sensor 30 determines that the pressure applied by the gasket 10 is derived from the human body.

Further, the controller 40 is also connected to the plurality of airbags 131 and the inflator 50, respectively, and the controller 40 can control the partial airbags 131 to deflate and simultaneously control the inflator 50 to inflate the other airbags 131. In addition, the controller 40 can continuously count the same human body posture. In actual application, the controller 40 determines that the human body posture is continuously changed according to the magnitude and distribution of the pressure sensed by the pressure sensor 20, and controls the partial airbag 131 to deflate when the continuous timing reaches the preset maximum time value. At the same time, the inflator 50 is controlled to inflate the other partial airbags 131.

It can be understood that the plurality of airbags 131 are respectively connected and communicated with the inflator 50 through the respective valves 132, and the airbags 131 are inflated after being filled with the gas, compared to the airbags 131 not filled with gas or the airbags filled with less gas. The 131 is at a high position, so it can push the human body to turn toward a lower position to change the human body posture.

The alerting device 60 is coupled to the controller 40 and is capable of alerting when the pressure sensor 20 senses that the edge region 120 is under pressure. In an actual application, the alerting device 60 may issue an alert only when the pressure sensor 20 senses that the edge region 120 is under pressure during the charging and deflation of the plurality of airbags 131. Specifically, the alerting device 60 may be a buzzer capable of emitting an audible alert information, or a vibrator capable of emitting a vibration alerting information, and may also include a buzzer and a vibrator.

In this embodiment, the pressure sensing inflatable cushion 100 is used to periodically turn over a long-term bedridden person with limited mobility. The shim 10 is a mattress that is generally rectangular and includes two opposing long sides and two opposing short sides. The central region 110 is generally circular with a line connecting the center of the circle to the center of the diagonal of the spacer 10 parallel to the two long sides of the spacer 10. The edge regions 120 are located at the two long sides of the spacer 10.

In addition, a through hole 111 may be formed in the central region 110 of the gasket 10 to facilitate the bedridden personnel to solve the drainage problem.

In this embodiment, the plurality of airbags 131 in the adjustment area 130 are divided into four airbag modules 1301. Each airbag module 1301 includes at least one airbag 131, and the four airbag modules 1301 are distributed in a 2×2 array. When two adjacent airbag modules 1301 are deflated, two adjacent airbag modules 1301 remain inflated.

In practical applications, the four airbag modules 1301 distributed in a 2×2 array are divided into upper right, lower right, upper left, and lower left according to the bed direction of the human body, and the adjacent two airbag modules 1301 in the upper right and lower right are inflated. When the two adjacent airbag modules 1301 in the upper left and lower left are deflated, the human body is in the left lying posture. When the two adjacent airbag modules 1301 in the upper left and lower left are inflated and the adjacent two airbag modules 1301 in the upper right and lower right are deflated, the human body is in the right side lying posture. When the adjacent two airbag modules 1301 in the upper right and upper left are inflated and the adjacent two airbag modules 1301 in the lower right and the lower left are deflated, the human body is in a supine posture.

It should be noted that the number of the airbag modules 1301 is not limited to four, and the arrangement is not limited to the 2×2 array distribution. In other embodiments, the adjustment region 130 may divide the other plurality of airbag modules 1301 according to the human body curve characteristics.

In this embodiment, the airbag 131 has a cylindrical shape and is disposed in parallel with the two long sides of the spacer 10. Each of the valves 132 is located at an end of the airbag 131 adjacent to the short side of the spacer 10 to facilitate charging and discharging of the airbag 131. It should be noted that the shape of the airbag 131 is not limited to a cylindrical shape. In other embodiments, the airbag 131 may also have other geometric shapes such as a circle, a direction, a sector, a polygon, and the like.

Further, the pressure sensing inflatable cushion 100 further includes an alert release device 70 coupled to the controller 40, and the alert release device 70 enables the controller 40 to control the alert device 60 to stop alerting. As described above, the warning device 60 alerts when the pressure sensor 20 senses that the edge region 120 is under pressure during the charging and deflation of the plurality of airbags 131, thereby reducing the presence of long-term bedridden personnel touching the edge region 120 during the turning process.
