ABSTRACT:
A digital safety device comprises a tubular member which fits snugly on the thumb or finger and includes a slot which quickly and securely receives the plunger of a conventional syringe. The slot is larger than the cross section of the plunger, but smaller than the head of the plunger, so that the plunger is retained in the tubular member and moves with the thumb in both the retracting and injecting directions. An inwardly tapering conical portion is defined at one end of the tubular member, so that the end fits snugly on the tapering portion of the thumb or finger. The slot allows quick and easy disengagement of the used plunger and syringe, while the safety device remains on the thumb or finger, ready to conveniently accept a new syringe with its plunger. An outwardly directed annular flange is provided on the tubular member to define a gripping formation, so that the digital device may be easily grasped for placement on or removal from the thumb or finger.
