  If you are on a bed for a long period of time, especially sacrum, head, buttocks, elbows, etc., which are susceptible to pressure, are likely to develop pressure ulcers. And beds have been proposed.

  Prior art documents related to such pressure ulcer prevention devices include the following.

Japanese Patent Laid-Open No. 7-1847777 JP 2000-217870 A

  FIG. 4 shows an “air bed” described in Patent Document 1. This bed is a side view showing the relationship between a pressure ulcer prevention air mat using a plurality of cylindrical air cells and a sleeping person using the air mat. 10 is a sleeping person lying on the air mat, 20a1, 20a2,... 20an are air mat A cell groups having pressure ulcer prevention functions, and 20b1, 20b2,. A group.

  The air cells of the A system and the B system are alternately arranged adjacent to each other in the direction perpendicular to the longitudinal direction of the air mat. The air cell groups of the A system and the B system are alternately pressurized and depressurized at a predetermined cycle by the pump 14 via the A system air pipe 13a and the B system air pipe 13b. Reference numeral 15 denotes a control unit that commands operation of the pump.

  In the state shown in the figure, the A system air cell group is pressurized and inflated, and the B system air cell group is decompressed and contracted. In this manner, pressure ulcers are prevented by alternately changing the portions where pressure is applied to the back of the sleeper by alternately expanding and contracting the adjacent air cells.
