The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, an embodiment of the present invention provides a pressure sensing inflatable cushion 100, which includes a cushion 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 gasket 10 includes a central region 110, edge regions 120, and adjustment regions 130, wherein the adjustment regions 130 are disposed between the edge regions 120 and distributed around the central region 110. The gasket 10 includes a plurality of air cells 131 located in the adjustment region 130 and a plurality of valves 132, the number of air cells 131 corresponding to the number of valves 132, each valve 132 for controlling the inflation and deflation of one air cell 131.

The working principle of the pressure sensing inflatable cushion 100 is as follows: the pad 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 accommodated in the gasket 10 and can sense the magnitude and distribution of pressure applied to the gasket 10 when the gasket 10 is subjected to pressure.

The temperature sensor 30 is housed in the pad 10 and connected to the pressure sensor 20, and the temperature sensor 30 can determine whether the pressure applied to the pad 10 is from a human body. It will be appreciated that the temperature sensor 30 determines whether the pressure applied to the pad 10 is from a human body based on whether the detected temperature value falls within a normal human body temperature range. In practice, the temperature sensor 30 is activated to determine whether the pressure applied to the pad 10 is from a human body when the pressure sensor 20 senses the 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 between the human body and the pad 10, and the size and shape of the contact surface can be known from the pressure size and distribution sensed by the pressure sensor 20. In practical applications, the controller 40 analyzes the posture of the human body according to the pressure and distribution sensed by the pressure sensor 20 when the temperature sensor 30 determines that the pressure applied to the pad 10 is from the human body.

Further, the controller 40 is also connected to the plurality of air bags 131 and the inflator 50, respectively, and the controller 40 can control the deflation of some of the air bags 131 and simultaneously control the inflator 50 to inflate the other air bags 131. In addition, the controller 40 can continuously time the same human posture. In practical application, the controller 40 determines that the human body posture is not changed during continuous timing according to the pressure magnitude and distribution sensed by the pressure sensor 20, and when the continuous timing reaches a preset maximum time value, the controller 40 controls a part of the air bags 131 to deflate and controls the inflator 50 to inflate the other part of the air bags 131.

It can be understood that the plurality of air cells 131 are respectively connected and communicated with the inflator 50 through the respective valves 132, and the air cells 131 are inflated after being inflated, so that the human body can be pushed to turn toward a lower position to change the posture of the human body compared with the air cells 131 which are not inflated or the air cells 131 which are inflated with a smaller amount of gas.

The warning device 60 is connected to the controller 40 and is capable of warning when the pressure sensor 20 senses that the edge area 120 is under pressure. In practical applications, the warning device 60 may only warn when the pressure sensor 20 senses that the edge area 120 is pressurized during the inflation and deflation of the plurality of air bags 131. Specifically, the warning device 60 may be a buzzer capable of emitting sound warning information, a vibrator capable of emitting vibration warning information, or both of the buzzer and the vibrator.

In this embodiment, the pressure sensing inflatable cushion 100 is used to turn over the patient in a timed manner for a long term bed-ridden patient with limited mobility. The pad 10 is a mattress that is generally rectangular and includes two opposing long sides and two opposing short sides. The central region 110 is substantially circular, with a line between the center of the circle and the center of the diagonal of the gasket 10 being parallel to the two long sides of the gasket 10. The edge regions 120 are located at both long sides of the gasket 10.

In practical application, the buttocks of the bedridden person are correspondingly placed in the central area 110 of the pad 10, so that the human body has a static supporting part when being turned over due to the change of the air bag 131 in the adjusting area 130, and the safety of the human body when the posture is changed is improved. In addition, a through hole 111 can be formed in the central area 110 of the pad 10 to help the bedridden person to resolve the problem of excretion.

In this embodiment, the plurality of airbags 131 in the adjustment region 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, wherein when two adjacent airbag modules 1301 deflate, the remaining two adjacent airbag modules 1301 inflate.

In practical application, four airbag modules 1301 distributed in a 2 × 2 array are divided into an upper right, a lower right, an upper left and a lower left according to the lying direction of a human body, and when two adjacent airbag modules 1301 positioned at the upper right and the lower right are inflated and two adjacent airbag modules 1301 positioned at the upper left and the lower left are deflated, the human body is in a left lateral lying posture. When the adjacent two airbag modules 1301 at the upper left and lower left are inflated and the adjacent two airbag modules 1301 at the upper right and lower right are deflated, the human body is in the right lateral lying posture. When the adjacent two airbag modules 1301 at the upper right and upper left are inflated and the adjacent two airbag modules 1301 at the lower right and lower left are deflated, the human body is in the supine position.

The number of the airbag modules 1301 is not limited to four, and the arrangement is not limited to a 2 × 2 array distribution. In other embodiments, the adjustment region 130 may divide other airbag modules 1301 according to the body curve characteristics.

In this embodiment, the air bags 131 are cylindrical and parallel to two long sides of the gasket 10, and each valve 132 is located at one end of a corresponding air bag 131 close to the short side of the gasket 10, so as to facilitate inflation and deflation of the air bags 131. It should be noted that the shape of the air bag 131 is not limited to a cylindrical shape, and in other embodiments, the air bag 131 may 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 comprises a warning release device 70 connected to the controller 40, wherein the warning release device 70 enables the controller 40 to control the warning device 60 to stop giving the warning. As described above, the warning device 60 warns when the pressure sensor 20 senses the pressure applied to the border area 120 during the inflation and deflation of the plurality of air bags 131, thereby reducing the possibility of danger to the bedridden person contacting the border area 120 during the turn. However, in the actual use process, there may be a case where another person accidentally touches the edge area 120 or the warning device 60 fails during the inflation and deflation of the airbag 131, and the warning releasing device 70 makes the warning function more humanized. In this embodiment, the alarm release device 70 is in the form of a button, and pressing the button stops the alarm device 60 from emitting the alarm.

Further, the pressure sensing inflatable cushion 100 further comprises a wireless communication device 80 connected to the controller 40, wherein the wireless communication device 80 is capable of sending the information of the human body posture, the holding time duration of the same posture or the alarm sending time duration to an external display terminal. Specifically, the display terminal may be an intelligent terminal with a display function, such as a mobile phone and a tablet computer. The display terminal is convenient for the holder of the display terminal, such as the relatives of the bedridden people to check the state of the bedridden people.

Further, the pressure-sensing inflatable cushion 100 further includes a heating device 90, and the heating device 90 is capable of heating the gas of the inflator 50 entering the airbag 131. It will be appreciated that in cold weather conditions, direct inflation of the bladder 131 with cold air may cause injury to the bed-ridden person.

In addition, other changes may be made by those skilled in the art without departing from the spirit of the invention, and it is intended that all such changes be considered within the scope of the invention.
