    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.

    摘要: A needle retraction apparatus comprising a body having a forwardly projecting needle, a needle retraction mechanism seated inside the body and biasing the needle rearwardly relative to the body, a slide member attachable to the body and having an opening communicating with a needle retraction cavity projecting away from the body, and an actuator rotatable relative to the slide member to reposition the slide member from a first position preventing needle retraction to a second position permitting needle retraction. An IV catheter introducer comprising the subject needle retraction apparatus is also disclosed.
