摘要：
A retractable needle device attachable to the front of a fluid collection or infusion device such as a syringe, the retractable needle device comprising a housing having an engagement member, a slide support surface, a retraction cavity and a first pinch surface a needle a needle alignment member comprising a needle tube and a second pinch surface and a needle retraction mechanism positioned within the needle tube and configured to bias the needle rearwardly wherein the first and second pinch surfaces are configured so that a pinching force applied to them will cause relative lateral movement between the housing and needle alignment member. This translational movement from an injection position, wherein the needle is aligned with the syringe connector, to a retraction position, wherein the needle is aligned with the retraction cavity, allows the needle retraction mechanism to force the needle into the retraction cavity.可回縮針裝置可附接到例如注射器之流體收集或灌注裝置的前端,該可回縮針裝置包括:外罩,其具有接合構件、滑動支持表面、回縮腔穴、第一捏縮表面;針;針對齊構件,其包括針管和第二捏縮表面;以及針回縮機制,其定位在針管裡並且建構成往後偏壓著針;其中第一和第二捏縮表面係建構成使得對它們施加的捏縮力將造成外罩和針對齊構件之間的相對側向移動。從針對齊於注射器連接器之注射位置到針對齊於回縮腔穴之回縮位置的這平移移動則允許針回縮機制迫使針進入回縮腔穴裡。20‧‧‧注射筒22‧‧‧魯厄式尖端、魯厄式圓錐構件23‧‧‧內螺紋25‧‧‧軸環27‧‧‧拇指帽29‧‧‧凸緣30‧‧‧可回縮針裝置32‧‧‧針35‧‧‧第一捏縮突耳38‧‧‧魯厄式鎖定管42‧‧‧回縮管54‧‧‧針管56‧‧‧第二捏縮突耳58‧‧‧維持夾66‧‧‧鎖定楔形物
