The air valve unit 108 and the air pump unit 110 constitute an execution unit module 118, and the execution unit module 118 and the main control circuit board 112 are disposed adjacent to the leg region F of the pad 102. The air pump unit 110 is connected to these air valve units 108A, 108B, 108C, and 108D, respectively. The switch power supply 114 is connected to an external power supply and can supply electric power necessary for the operation of the member.
The main control circuit board 112 includes a power processing circuit 120, a data logic processing and control circuit 122, and a driving circuit 124. The power processing circuit 120 is connected to the switch power supply 114, and the data logic processing and control circuit 122 is Are connected to the power processing circuit 120, the driving circuit 124, and the operation interface 116, respectively. The drive circuit 124 is connected to the air pump unit 110 and the air valve unit 108, respectively. The operation interface 116 includes a display circuit 126, a key circuit 128, and a logic processing circuit 130, and the key circuit 128 is connected to the display circuit 126 and the logic processing circuit 130, respectively. A display screen 132 and a key group 134 are provided outside the operation interface 116, the display screen 132 is connected to the display circuit 126, and the key group 134 is connected to the key circuit 128. In other embodiments, the number of air pump units and air valve units may be changed as needed for use.

In this embodiment, the air valve unit 108A and the air pump unit 110 are turned over in the support air cushion 104 in the head region A and in the right half region B1 of the neck through the piping a, piping b, and piping c as needed. The air cushion 106 and the lying air cushion 106 in the neck left half region B2 can be supplied and exhausted, respectively. The air valve unit 108B and the air pump unit 110 are supplied to the turning air cushion 106 in the back right half region C1 and the turning air cushion 106 in the back left half region C2, respectively, through the piping d and piping e as needed. Air or exhaust is possible. The air valve unit 108C and the air pump unit 110 supply air to the turnover air cushion 106 in the thigh right half region D1 and the turnover air cushion 106 in the knee right half region E1 through the pipe f as necessary. Or exhaust is possible. The air valve unit 108C and the air pump unit 110 supply air to the turnover air cushion 106 of the thigh left half region D2 and the turnover air cushion 106 of the knee left half region E2 through the pipe g as needed. Or exhaust is possible. The air valve unit 108D and the air pump unit 110 can supply and exhaust air to and from the support air cushion 104 in the leg region F, as needed, through the pipe h.
In other embodiments, the number of pipes may be changed as needed for use. When supplying air to each turnover air cushion 106, the depression angle between the upper surface of each turnover air cushion 106 and the pad 102 may be between 30 and 90 degrees, or between 90 and 180 degrees. At 90 degrees, the bedridden hits most comfortably.
In the present embodiment, when air is supplied to the lying air cushion 106 in the knee right half region E1 and the knee left half region E2, the air supply state is developed from the exhaust state to the right side and the left side, respectively. In addition, when the air cushion 106 lying down in the right half knee region E1 and the left half knee region E2 is exhausted from the air supply state, the air cushion 106 contracts to the left side and the right side to enter the exhaust state. However, the deployment and contraction directions of the lying air cushion 106 in the right knee half area E1 and the left knee half area E2 are not limited thereto. For example, in another embodiment, when the air cushion 106 is turned over from the knee right half region E1 and the knee left half region E2 from the exhaust state, the air cushion 106 expands upward and enters the air supply state. Further, when the air cushion 106 lying over the knee right half region E1 and the knee left half region E2 is exhausted from the air supply state, the air cushion 106 contracts downward and enters the exhaust state.

A plurality of different commands are stored in the logic processing circuit 130 of the operation interface 106, and each key of the key group 134 represents each command. When a key is pressed, the command represented by this key is sent to the data logic processing and control circuit 122 of the main control circuit board 112 for processing. Subsequently, the drive circuit 124 selectively drives at least one of the air pump unit 110 and the air valve units 108A, 108B, 108C, and 108D based on the content of the command, so that the support air cushion 104 and the rolling air cushion 106 are turned on. At least one of the air is supplied. Then, the display screen 132 of the operation interface 106 displays the characters “image supply” or image information.
When another key is pressed, the driving circuit 124 first drives at least one of the air pump unit 110 and the air valve units 108A, 108B, 108C, and 108D to supply air to the supporting air cushions 104. Then, the air cushion 106 is turned over and exhausted. Then, the display screen 132 of the operation interface 106 displays “exhaust” characters or image information. Subsequently, the drive circuit 124 drives the air pump unit 110 and at least one of these air valve units 108A, 108B, 108C, and 108D based on a new command, so that the support air cushion 104 and the rollover air cushion at different positions are driven. 106 can be supplied with air. Then, the display screen 132 of the operation interface 106 displays the characters “image supply” or image information again.
