The present invention relates to a device (1) for vacuuming and closing a vent tube of a medical container (27), including a first variable pressure chamber (5) configured to be connected to a-vacuum pump (39). A body (2) that defines the internal volume, such that the body (2) communicates the proximal end of the medical container (27) with the first variable pressure chamber (5). A movable passage between the proximal rest position and the distal operating position along the longitudinal axis (A), inside the body and the internal volume of the body (2), configured to accept A vent device (12) that includes a trachea (13), the vent tube (13) passes through the first variable pressure chamber (5) to the inside of the medical container (27), and the vent tube (13) A second variable pressure chamber (13) having an internal volume configured to include a stopper (26) in a compressed state and having a vent pipe (13) connected to a vacuum pump (39). The ventilation device (12) communicating with 20) and the inside of the internal volume of the-vent pipe (13) can be moved along the longitudinal axis (A) between the proximal rest position and the distal operating position. When the ventilation pipe (13) is in the operating position, the piston rod (24) pushes the stopper (26) into the medical container (27), and the piston rod (24) and-. A container holder system (28) provided in the main body (2) and communicating with the first variable pressure chamber (5), the container holder system (28) is a medical container (27) to be closed. Aligned with the direction of movement of the vent tube (13) to accept the proximal end of the vent and to allow the vent tube (13) to enter the medical vessel (27) when moving from the proximal rest position to the distal operating position. Includes a container holder system, which is configured to hold the medical container (27).本発明は、医療容器（２７）を真空および通気管閉栓するためのデバイス（１）に関し、 － 真空ポンプ（３９）に接続されるように構成された第１の可変圧力室（５）を含む内部容積を画定する本体（２）であって、本体（２）は、医療容器
