The cuff pressure control device (100) is provided with a control unit (111), a cuff pressure-detecting unit (171), a suction pressure-detecting unit (173), a pump (110), a valve (120), a valve (130), a filter (176), and a tank (160). The valve (120) comprises: a first air hole (121) connected to the discharge hole (110B) of the pump (110); a second air hole (122) connected to the cuff (10) via an air supply tube (175); and a fifth air hole (125) that communicates with the outside of the valve housing (129). The valve (130) comprises: a third air hole (133) connected to the suction hole (110A) of the pump (110); a fourth air hole (134) connected to a suction tube (141), the tip (141A) of which faces the cuff (10), a suction tube (142), and a suction tube (143); and a sixth air hole (136) that communicates with the outside of the valve housing (139). |
