摘要： A needle shield assembly with a needle having a distal tip and a static feature is provided. The needle shield assembly includes an adapter having an open distal terminus and an open proximal terminus to allow passage of the needle and a needle shield slidably associated with the adapter having an open distal end and an open proximal end where the open proximal end is sufficiently narrow to restrict proximal movement of the needle static feature causing the shield to move in a proximal direction when the needle is pulled proximally after the static feature has established contact with the needle shield proximal end. The assembly includes a canting plate having an unactivated first position and an activated second position that restricts needle movement. The canting plate is activated via a canting plate retention system in communication with the canting plate and responsive to proximal movement of the needle.

摘要： A medical needle assembly includes a needle cannula having a body and a tip. The tip is disposed at a distal end of the cannula. An elongate member has a first end and a second end. The first end is fixedly attached to the body of the needle cannula at a connection point and the second end extends radially outward from the needle body. A shield is slidingly mounted to the needle for movement between a proximal position to a distal position. The shield includes a shield body having a central chamber, a distal end and a proximal end as well as a plate secured to the shield body and defining an aperture. As the shield is moved from the proximal position to the distal position, the place displaces the second end of the elongate member to a position near the needle cannula, permitting the elongate member to pass through the aperture. When the shield is in the distal position, the send end of the elongate member extends radially outward from the needle body, preventing passage of the elongate member through the aperture. The elongate member may be a leaf spring. A feature may be secured to the body of the cannula to restrict movement of the shield with respect to the needle.

摘要翻译： 医疗针组件包括具有主体和尖端的针插管。 尖端设置在套管的远端。 细长构件具有第一端和第二端。 第一端在连接点处固定地附接到针插管的主体，并且第二端从针体径向向外延伸。 屏蔽件滑动地安装到针上以在近端位置到远端位置之间移动。 护罩包括具有中心室，远端和近端的屏蔽体以及固定到屏蔽体并限定孔的板。 当护罩从近侧位置移动到远端位置时，该位置将细长构件的第二端移动到靠近针管的位置，允许细长构件穿过孔。 当护罩处于远侧位置时，细长构件的送出端从针体径向向外延伸，从而防止细长构件穿过孔的通道。 细长构件可以是板簧。 特征可以固定到套管的主体以限制护罩相对于针的移动。
