Abstract

A valve for the closure of fluid channels, in particular for use in disposable cartridges for extracorporeal circulations, having a valve body with a pressure channel, and a sealing cap, which can cooperate with the valve body in such a way that it closes off the end of the pressure channel on the valve body side against the surroundings. The valve is designed in such a way that a pressure chamber can be formed between the pressure channel and the sealing cap, and the sealing cap has a deformable sealing area for entry into a fluid channel in order to close the latter. The valve may be incorporated within a device for use with a disposable cartridge for at least one fluid channel.
