ABSTRACT:
An assembly of a needle, catheter, and a device for selectively protecting the needle tip from inadvertent needle sticks by an elongate housing having an extending needle and a needle guard adapted for sliding movement relative the housing. The needle guard is formed to carry a catheter hub and catheter, and includes an actuation tab to enable selective sliding movement of the needle guard relative the housing and along the length of the needle. The housing is adapted to be held within one hand to permit insertion of the needle and catheter into a patient, and after insertion, the needle may be withdrawn from the patient and covered by the needle guard by pressing against the actuation tab while slidably retracting the housing and needle relative to the needle guard; upon full retraction of the housing, a detent mechanism formed between the housing and needle guard locks the needle guard about the length of the needle and prevents accidental contact with the needle tip.
