ABSTRACT:
A needle removal/containment and transport apparatus for potentially injurious medical implements. The needle removal device portion comprises a plate member formed with a first receiving slot, and an integral needle engaging member comprising a pair of opposed finger members integrated with a base member to form a stepped slot providing a second receiving slot and a contiguous engaging slot. The first receiving slot is laterally aligned with the second receiving slot at an elevation generally higher with respect thereto. The needle hub is slidably translated through the second receiving slot into engagement with the needle removal device via the engaging slot whereupon the syringe can be rotated relative to the needle hub to unthread the needle from the syringe. The unthreaded needle and syringe are then removed from the engaging slot and translated through the second receiving slot and into the first receiving slot such that the needle hub is dispose on the underside of the plate member permitting the needle to drop into the container. In the event the needle has not been fully unthreaded from the syringe or in the case of a multi-sample needle where the needle can hang-up within the syringe, the needle hub will engage the underside of the plate member in response to upward forces applied to the syringe to act as a stop preventing the needle from being pulled out of the removal device.
