Holding device for a medical device

Holding device (1) for assembling a medical device, which holding device (1) comprises

• (a) a receiving vessel (2) comprising
• (1) a jacket portion (4) with a longitudinal axis (5) and having an open end and
• (2) a front wall (8) closing an end (7) of the receiving vessel opposite the open end (6) and
• (3) the jacket portion (4) and front wall (8) defining a receiving chamber (9),
• (b) a first connecting part (23) disposed close to the front wall (8) on the jacket portion (4), projecting in the direction towards the longitudinal axis (5) and extending continuously around the periphery,
• (c) a retaining part (20) connected to the front wall (8) of the receiving vessel (2) and projecting therefrom in a direction remote from the jacket portion (4), the retaining part (20) being arranged eccentrically with respect to the longitudinal axis (5) and defining a flow passage (21),
• (d) a cannula (11) having one end (12) facing the front wall (8) of the receiving vessel (2) and an opposite end (13) facing the open end (6) of the receiving vessel (2), the cannula (11) defining a flow-through bore,
• (e) a holder (3) for the cannula (11), the holder (3) comprising
• (1) a support part (14) with a periphery facing the jacket portion (4) of the receiving vessel (2),
• (2) a support (10) holding the cannula (11) in a fixed position in a gas-tight and liquid-proof manner, the opposite end (13) of the cannula (11) projecting beyond the support (10),
• (3) the support part (14) of the holder (3) and the front wall (8) of the receiving vessel (2) defining a connecting passage (22) therebetween, the connecting passage connecting the flow passage of the holding part (20) with the flow-through bore of the cannula (11), and
• (f) a second connecting part (24) extending continuously around the periphery of the support part (14) and designed to connect to the first connecting part (23) of the receiving vessel,
• (g) means on at least one of the connecting parts (23, 24), said means being designed as an energy directing means (29) for providing a continuous circumferential gas-tight and liquid-proof joint between the holder (3) and the receiving vessel (2) and
• (h) a selectively openable valve arrangement disposed between the connecting passage (22) and the receiving chamber (9), the valve arrangement comprising (1) a hose valve (15) disposed between the cannula (11) and the receiving chamber (9).
