A valve device (200) for a closed system for endotracheal aspiration of a patient via a catheter. The device (200) comprises a valve chamber (220, 222) that can be connected to a vacuum source and to the catheter, a valve body (250) arranged in the valve chamber (220, 222), a manually operated actuator button (210) for the valve body (215), a coupling (260) engaging the valve body (250) and to the actuator button (210) for transmitting a movement of the actuator button (210) to the valve button (250), a spring device for holding the valve body (250) in the first position. The device is characterised in that the wall (216) that delimits the valve chamber (220, 222) comprises an opening (219) for receiving the valve body (250), that a resilient membrane (253) forms a sealing of the opening (219) within the valve housing (215), that the resilient membrane is connected to the valve body and the valve housing (215), respectively, and that the coupling (260) extends exteriorly relative to the valve housing (215). |
