Abstract
The invention relates to a safety blood collecting device adapted to prevent accidental puncturing of attending medical personnel by an infected blood collecting needle. The blood collecting device has a forward conical portion which is provided with a vein aligning groove to allow convenient positioning of the needle guard in relation to the vein of the patient for precise injection of the needle. One or more resilient depressible locking tabs are carried by the needle guard and extend through corresponding aligned openings formed in the casing to lock the needle guard in an extended position covering the needle. When the locking tabs are depressed and an inward pressure is exerted on the forward end of the needle guard, the needle guard can be moved against the tension of a coil spring inside the casing and uncover the blood collecting needle to allow withdrawing of the blood from the patient.
