Injection valve for puncture implements or infusion devices

摘要

The invention provides an injection component which can be easily disinfected by avoiding a moist chamber above the closure element, has a closure mechanism which can be opened very easily, and gives a reliably tight closure even after actuation many times, so that no contamination is able to penetrate into a liquid line. For this purpose, the closure element has a membrane (18) which is convex outwards and is formed on one side of a ring (17) which is fixed in the vicinity of the outer opening of the channel (14) in a housing (10). The membrane (18) is provided in its middle with perforations (19) to allow the injectate from a syringe tip (24) to pass through. A clamping ring (21) is used to secure it. <IMAGE>
