<p>This invention is a protective shield (18) for a blood sampling unit that is movably engaged to an adapter (10) having a needle (12) attached. The shield attaches to a tube holder when the needle is covered by the shield. Longitudinal grooves (56) on the adapter (52) guide the shield between a first position, covering the needle, and a second position, exposing the needle. The shield can be locked in either the first position or the second position. The blood sampling unit is safely disassembled or re-assembled when the needle is covered by the shield. In an embodiment of the invention, a tip protector (42), removably attached to the adapter, extends through the length of the tube holder (44) to prevent needlesticks. The blood sampling unit and the tube holder can be assembled and disassembled when the tip protector is attached to the adapter, covering the needle. The tip protector is removed during a clinical procedure and then replaced after the clinical procedure is finished.</p> |
