Disclosed is a vacuum tube type collection device for collecting blood or other body fluids from a patient. The device includes a conventional sealed vacuum tube (12) received in a tube holder (14) having a removable needle assembly (16) connected to the tube holder. The characterizing feature of the device of this invention is that the needle assembly has a guard member (70) which protects the exposed tip of the needle after withdrawal of the needle from the patient's body. This member is movable between a first position where the tip of the needle is exposed and a second position where the guard member covers the tip of the needle and prevents needle sticks. A locking element is mounted along the needle shaft which permanently locks the guard member in the second position upon movement of the guard member into the second position. |
