A valve device for a hub member of a catheter or the like. An open cup-shaped hollow cylinder with a slit bottom portion is axially displaceable in the chamber of the housing of the hub member. In the closed position, a helical spring presses the edge of the opening of the hollow cylinder against the inner end of an insertion opening for a connecting member. The insertion opening is formed at the housing and has a diameter larger than the inner circumference of the edge of the opening of the hollow cylinder. The bottom portion is pulled into an adapted central hole of a closing ring fixed in the housing, through which hole the bottom portion may be pushed axially against the spring action for releasing its legs formed by the slit. Throughout this operation the resilient hollow cylinder is free of stresses, so that the edges of the slit in the bottom portion are not deformed. Nevertheless, the closing ring ensures an effective closure of the flow channel in the hub member, sealing it both against air entering the hub member and against blood oozing out.

Hub member

A valve for simultaneously closing the outlets of a plurality of containers in communication with the valve, and an outlet from the valve, comprising a valve housing having a plurality of inlet openings corresponding to the number of container outlets to be sealed, and at least one outlet; a sealing element adjustably positioned in the valve housing for simultaneously sealing the valve housing inlets and outlet so as to seal off liquid communication between the containers, and between the containers and the exterior; and an arm connected to the sealing element for actuation of the sealing element exterior of the valve housing.
