The mattress member 1 has a body rest portion of six rows and nine rows.
It is composed of 144 cells 4 divided into columns. Air is supplied to or discharged from each cell 4 from a compressor 7 via a solenoid valve 5 and an air tube 6. Thus, the air pressure in each cell 4, that is, the mounting surface of each cell 4 can be moved up and down to adjust the support state of the body. A pressure sensor 8 is provided at the center of the mounting surface of each cell 4. The pressure sensor 8 is used to detect a body on the mattress member 1 and specify the range.

The display device 2 has a touch panel 9. On the main screen of the touch panel 9, as shown in FIG. 2A, in addition to the mattress state diagram 10, various buttons and comment display fields are displayed. The mattress state diagram 10 is composed of grid lines divided into 6 rows and 9 columns so as to correspond to the cells 4. In the mattress state diagram 10, one of the body lying states (body patterns) registered in a pattern as described later is selected based on the pressure detected by the pressure sensor 8. Is displayed. Buttons are MANUAL button 13, UP button 1
4, a DOWN button 15, an AUTO button 16, and a user registration button 17. MANUAL button 1
3, UP button 14 and DOWN button 15 are used when each cell 4 is manually moved up and down by touching a desired portion of the mattress state diagram 10. That is, after the MANUAL button 13 is operated, a desired operation in the mattress state diagram 10 is touched, and the UP button 14 is operated.
Alternatively, the corresponding cell 4 can be moved up or down by operating the DOWN button 15. The AUTO button 16 is used when controlling the pressure of each cell 4 according to a control program registered in advance. User registration button 1
7 is used when switching to the user information registration screen. On the user information registration screen, as shown in FIG. 2B, a user selection button 18, various input fields 19, a registration button 20, and an end button 21 are displayed. The user selection button 17 is used to register personal data input in advance in each input field 18. Here, personal data for three persons can be registered, but the number can be freely set. In the input column 19, a height column, a weight column, an age column,
Gender column is included. Data input to each input field 19 is performed using a ten-key (not shown). The registration button 20 is used to store the data after inputting the data into the input field. When the end button 21 is operated, the screen is switched to the main screen.

The control unit 3 includes a storage unit 22 and a calculation unit 23
And built-in. The storage unit 22 stores a plurality of body patterns in a record format in advance. FIG. 5 (a)
(C) shows examples of body patterns to be stored. The calculation unit 23 performs pattern recognition of the load point based on the pressure detected by the pressure sensor 8. Then, one similar pattern is extracted from the body patterns stored in the storage unit 22. Further, the size of the extracted body pattern is changed to a mattress state diagram displayed on the touch panel 9 of the display device 2 and displayed as a body state diagram 11. The arithmetic unit 23 changes the display on the touch panel 9 based on the touch operation on the touch panel 9 and the electromagnetic valve 5 and the compressor 7 for moving each cell 4 up and down.

2) Switch to the user information registration screen (step S
3) Read personal data (step S4). In this case, if the personal data has not been registered, the data is registered by inputting the data in each input field. If the personal data has been registered, the corresponding user selection button is touched. As a result, the trouble of input can be saved, and efficient input can be performed.

Subsequently, a body detection process is performed. In the body detection process, as shown in the flowchart of FIG. 4, the user operates the mattress member 1 based on the pressure detected by the pressure sensor 8.
It is determined whether the patient is lying down (step S21).
If lying down, the position of the body is recognized as a pattern based on the pressure detected by the pressure sensor 8 (step S22). Then, the closest one of the body patterns stored in the table of the storage unit 22 is called based on the obtained recognition pattern (step S23). The size of the called body pattern is adjusted based on the registered personal data (height, weight, etc.) by, for example, changing the vertical and horizontal directions or a part of the magnification (step S24), and displayed on the touch panel 9. The mattress state is displayed superimposed on the diagram 10 (step S15). As a result, the body pattern can be displayed as the body state diagram 11 at a substantially accurate position in the mattress state diagram 10, and the desired cell 4 can be easily and reliably operated.

When the body detection process (FIG. 4) is completed, it is determined which of the MANUAL button 13 and the AUTO button 16 has been touched on the main screen (step S6). When the MANUAL button 13 is touch-operated, the mattress state of the touch panel 9 in FIG.
A touch operation is performed on a portion corresponding to the cell 4 desired to be driven (step S7), and the UP button 14 or DOWN
When one of the buttons 15 is operated (step S8), the mounting surface of the corresponding cell 4 is moved up or down (step S9 or S10). On the other hand, when the AUTO button 16 is operated, the pressure control of each cell 4 is performed based on the control program registered in advance (step S1).
