摘要： Valves are disclosed including a housing having at least one fluid inlet and at least one fluid outlet, a valve seat for at least one of the fluid inlets and fluid outlets, a diaphragm movable between a first position engaged with the valve seat and a second position disengaged from the valve seat, the diaphragm having a surface area which is greater than the size of the valve seat so that the surface area of the diaphragm is greater than the surface area necessary for abutment against the valve seat, an actuator for actuating the diaphragm between the first and second positions, and an activator for displacing the diaphragm whereby at least partially portions of the surface area of the diaphragm are exposed to the valve seat upon displacement of the diaphragm.

摘要： A needle holding device having an elongated hollow body with first and second ends, the first end being substantially open for receiving a needle. The hollow body also has a locking member operably disposed therein or thereon. The locking member has an opening to receive and non-releasably hold a needle inserted therethrough. Preferably, the locking member has one or more protrusions directed inwardly toward said opening, the protrusions being adapted to engage a needle in a locking relationship when the needle is inserted through the opening in the locking member. Also preferably, the needle holding device has an elastomeric sealing member operably connected to the hollow body, the elastomeric sealing member also being disposed adjacent the first end of said hollow body. The elastomeric sealing member is adapted to admit and seal around a needle pierced therethrough.
摘要翻译：一种针保持装置，其具有带有第一和第二端部的细长中空体，所述第一端基本上是开口的，用于接收针头。中空体还具有可操作地设置在其中或其上的锁定构件。锁定构件具有用于接收和不可释放地保持插入其中的针的开口。优选地，锁定构件具有朝向所述开口向内指向的一个或多个突起，当针穿过锁定构件中的开口插入时，突起适于以锁定关系接合针。还优选地，针保持装置具有可操作地连接到中空体的弹性体密封构件，弹性体密封构件也邻近所述中空体的第一端设置。弹性体密封构件适于在穿过其中的针的周围进入和密封。
