Abstract:
1. A needle retraction apparatus for use with medical devices, said medical devices including liquid infusion devices and liquid collection devices, the apparatus comprising: a body; a retractable needle assembly further comprising a needle projecting forwardly from the body; a slide member supported by the body, the slide member further comprising a rearwardly projecting needle retraction chamber; and an actuator rotatably supported by and connected to the slide member, the actuator further comprising a connector member providing fluid communication with the liquid infusion device or liquid collection device; wherein the body is attachable to the slide member so that relative movement between the body and slide member is limited to sliding movement that is linear and translation in a plane transverse to a longitude axis through the needle; and wherein rotation of the actuator relative to the slide member initiates needle retraction by causing the needle retraction chamber to slide transversely into alignment with the needle.
