Surgical fluid transfer apparatus

摘要

A surgical fluid transfer apparatus for passage of fluids includes a hub defining a longitudinal axis and having an internal chamber, an elongated member extending from the hub and defining a longitudinal conduit and a closure valve disposed within the internal chamber of the hub. The closure valve is adapted for movement between a first position substantially sealing the internal chamber to prevent passage of fluids and a second position establishing a fluid passage within the hub to permit passage of fluids therethrough. The closure valve includes a valve housing having inner wall portions defining a general tapered internal bore and a seal member at least partially disposed within the tapered internal bore of the valve housing. The seal member defines a general tapered configuration and has an open condition permitting passage of an access instrument through the closure valve and into the longitudinal conduit of the elongated member and a closed condition in the absence of the access instrument. The inner wall portions of the valve housing cooperate with the seal member to permit the seal member to assume the closed condition thereof.
