Telescoping needle shield |
摘要 |
A needle assembly having a telescoping shield that extends over the distal end of the needle when released by an actuator that is triggered during a standard sequence of operation of a medical procedure. For example, the telescoping shield extends by a compression spring from a starting retracted position to a venipuncture partially extended position during the standard sequence of operation of drawing a blood sample with an evacuated blood collection tube and needle holder. After the procedure is complete and the needle is removed from the patient the shield continues to extend to a fully extended and locked position over the distal end of the needle rendering the needle safe and preventing needle stick injuries.
