A medical connector comprising a housing with a central axis and an internal cavity. The internal cavity of the housing comprises a passage connecting a first region and a second region and a rigid valve member configured to be advanced towards and away from the second region along the central axis of the housing, the rigid valve member comprising an internal passageway and a fluid chamber at one end of the valve member. The fluid chamber has a closed tip and a hole adjacent the closed tip. The medical connector has a first position in which at least a portion of the fluid chamber comprising the hole is positioned in the passage and fluid flow between the internal passageway and the first region is impeded. The medical connector also has a second position in which the rigid valve member is advanced towards the first region and fluid communication between the interior of the medical connector and the first region via the hole is enabled.一種注射器連接器包括一殼體,該殼體具備含有一公注射器末梢之第一端以及一第二端。該連接器更包含一具有一第一開放端和一第二密閉端的剛性閥構件以及一被建構用來耦接該閥構件與該殼體的固持構件。該殼體更包含一被定位在該殼體內且與該殼體第二端流體連通的剛性導管,該剛性導管適於接合該閥構件第一開放端。該殼體在該閥構件處於一第一位置時含有一第一內部容積,且在該閥構件處於一第二位置時含有一較小的第二內部容積。900...可關閉公注射器連接器902...公端904...母端906...外殼908...覆緣910...彈性構件912...內部閥構件914...內部密封部分916...內部流體通路918...通路916在公端902內的區域920...通路916在連接器900中間的區域922...通路916較接近母端904的區域924...通路916之區域926...窄開口928...連接區域930...窄開口932...內部導管934...底座936...中間部分938...內部導管940...密封元件
