Provided is a medical suction device that can easily store and remove a storage bag from a bottle even when attached to a vertical surface. A cover body includes a mounting member A in which a pressure adjusting mechanism 2 is disposed and a mounting piece 6 is disposed at a predetermined position, a passage 11 on which the pressure adjusted by the mounting member acts, and a bottle fixing claw 13a. 10, a hanging piece 20 having a rotating shaft 21a disposed on the lower end side thereof and a refracting link piece 22a connected above the rotating shaft, and a lower end side supported by the rotating shaft and bent above the rotating shaft. A main body B having a bottle support 30 having a link hole 22b connected thereto and a fitting hole 31 formed at a predetermined position, and a support having an upper end opened and fitted and supported in the fitting hole of the bottle support. And a bottle C on which a projection 44 is formed. The bottle supporting projection is formed by fitting the support projection of the bottle into the fitting hole of the bottle support, and the bottle support is rotated to fix the bottle fixing claw of the bottle. It is engaged with a part of the upper edge 41 and attached to the main body.
