Disclosed is an automatic fluid discharge and drainage device comprising a drainage vessel (1) provided with a fluid storage chamber (11). A fluid inlet (15) and a fluid outlet (21) are arranged on the fluid storage chamber (11). The drainage vessel (1) is provided with a movable sealing gasket (3) which is capable of sealing the fluid outlet (21), and is also provided with a control device (4) which is equipped with a remote control receiving module and which can forcibly control the movable sealing gasket (3) to open the fluid outlet (21), or a control device (4) which can monitor the fluid level in the fluid storage chamber to open or close the fluid outlet (21) through the movable sealing gasket (3). In the present device, the movement of the movable sealing gasket (3) can be controlled by remotely triggering the control device (4) by means of the remote control contacting module or by monitoring the fluid level condition to activate the control device (4), whereby the opening and the closing of the fluid outlet (21) can be indirectly controlled. The accuracy of this fluid discharge and drainage device is higher, and there is no need to carry out the fluid discharge process manually, the fluid drainage condition can be recorded precisely, the labour intensity of nursing personnel can be reduced effectively and operator infection can be avoided, thus having better safety and convenience, and being used in the field of medical instruments.Linvention concerne un dispositif de drainage et dévacuation automatique de fluide comprenant un récipient de drainage (1) pourvu dune chambre de stockage de fluide (11).
