Abstract
An assembly of a needle, catheter, and a device for selectively protecting the needle tip from inadvertent needle sticks is disclosed, characterized by use of elongate housing, having a needle extending therefrom, and a needle guard adapted for sliding movement relative the housing. The needle guard is formed to carry a catheter hub and catheter thereupon, 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within one hand to permit insertion of the needle and catheter into a patient, and after insertion, the needle may be withdrawn from the patient and covered by the needle guard merely by pressing against the actuation tab with the index finger of the hand of a user, while slidably retracting the housing and needle relative the needle guard by use of the thumb and middle finger. Upon full retraction of the housing relative the needle guard, a detent mechanism formed between the housing and needle guard is engaged, to permanently lock the needle guard about the length of the needle and prevent accidental contact with the tip of the needle.
