A normally closed valve that may be opened upon insertion of a nozzle permits two-way flow when opened by a luer-taper nozzle. The valve also is able to resist large back pressures. The valve includes a substantially rigid housing that defines a passageway having an inlet section and an outlet section. The housing has an exterior inlet face to which the inlet section opens. The inlet section preferably has tapered and expanding zones. The tapered zone is adjacent to the exterior inlet face and is shaped to receive the nozzle. The expanding zone is adjacent to the tapered zone and has a larger inner diameter than the tapered zone's inner diameter. The exterior of the inlet section of the housing may have threads to accept luer-lock threads that may surround the nozzle.

[ We claim:] [1.] A normally closed valve that may be opened upon insertion of a luer-tapered nozzle, the valve comprising:a housing defining a passageway having an inlet section and an outlet section, the housing being substantially rigid and having an exterior inlet face to which the inlet section opens;a substantially rigid cannula disposed within the passageway and extending into the inlet section, the cannula being movable between first and second positions corresponding to closed and open modes of the valve, the cannula having an inlet end and an outlet end;a substantially flexible, resilient gland member havinga seal section disposed over the inlet end of the cannula, the seal section having a normally closed aperture therethrough,a tubular section connected to the seal section and disposed around the cannula between cannula and the housing, andan attachment section connected to the tubular section and attached to the housing;wherein, when the valve is in its closed mode, the seal section is substantially aligned with the exterior inlet face of the housing so as to provide a swabbable surface.
