Abstract
A valve for medical use has a cannula mounted on a hub and fixed in a fluid conduit so that the cannula points upstream. An elastomeric valve element is mounted on the hub within the conduit so as to enclose the cannula. The valve element has a first solid portion of circular cross-section disposed upstream of the cannula point which closes the conduit, a second hollow frustoconical portion within which the cannula point is disposed, and a third hollow cylindrical portion surrounding the cannula downstream from its point and fixed to the hub. The second portion has a frustoconical interior passageway. In use, the valve element is compressed by application of a medical appliance to the valve element first portion to cause the cannula point to pierce the first portion to provide a path for fluid flow through the conduit.
