摘要： A female luer connector for intravascular or urological use is provided with a needle having a closed distal end with an opening in the side of the needle. In addition, the needle is sealingly received within a recess of a rubber septum with an interference fit between the distal end of the needle and the septum. A slit may be formed in the septum to facilitate penetration of the needle through the septum when in use. In one embodiment, the septum has an elongated recess so that the needle may be received under compression in one portion for storage purposes and in a second portion when in use.

摘要： The protected needle assembly employs a retractable sheath which can be moved from an extended protected position over a hollow needle to a retracted position exposing the hollow needle. A projection carried on the sheath is disposed in a guide slot having a circumferentially directed portion for receiving the projection. In addition, a spring or resilient sleeve is provided between the movable sheath and the housing to not only bias the sheath longitudinally of the hollow needle but also in a circumferential manner. In order to release the sheath, the needle assembly is brought into contact with a patient's skin or a septum and twisted. Thereafter, an axial force on the needle assembly causes the sheath to be retracted while the hollow needle penetrates through the skin or septum. Other embodiments are provided wherein a blunt needle can be moved within a hollow needle from an extended position protecting the hollow needle and a retracted position permitting exposure of the hollow needle.
摘要翻译：受保护的针组件采用可伸缩护套，其可以从中空针头上的扩展保护位置移动到露出中空针头的缩回位置。承载在护套上的突出部设置在具有用于接收突起的周向定向部分的引导槽中。此外，弹性或弹性套筒设置在可移动护套和壳体之间，以便不仅沿着中空针头的纵向偏置护套，而且还以周向方式。为了释放护套，使针组件与患者的皮肤或隔膜接触并扭曲。此后，针组件上的轴向力使护套缩回，而中空针穿透皮肤或隔膜。提供了其它实施例，其中钝针可以从保护中空针的延伸位置的中空针中移动，并且允许中空针的暴露的缩回位置。

摘要翻译：用于血管内或尿路使用的女性鲁尔连接器设置有具有封闭的远端的针，针在针的侧面具有开口。此外，针被密封地容纳在橡胶隔膜的凹部内，在针的远端和隔膜之间具有过盈配合。可以在隔膜中形成狭缝以便于在使用时针穿过隔膜。在一个实施例中，隔膜具有细长的凹部，使得针可以在一部分中被压缩接收用于存储目的，并且在使用时可以在第二部分中。
