A pad for effectively preventing bed sore is realized. This pad for preventing bed sore comprises: cushion pads for supporting portions susceptible to bed sore; sensor switches provided at the portions susceptible to bed sore and turned on when a pressure higher than a bed sore pressure acts thereto; exposed electrodes which are disposed around the susceptible portions; and a controller. The controller supplies current of low frequencies when a pressure is continued over a predetermined period of time, increases a current value with an increase in the time of continuance of pressure and continues current supply even after the release of pressure, when the pressure is continued over a predetermined period of time. When the pressure is continued, the supply of current prevents circulation from slowing, promotes circulation facilitating action with the continuance of the pressure, and further, quickens the restoration of circulation after the release of the pressure. Disuse atrophy of a group of muscles around a portion susceptible to bed sore can be prevented by the current supply, so that the load of the pressure to a susceptible portion can be dispersed. |
