Abstract
Abstract A finger guard is provided for use with a storage tube for a hypodermic needle to prevent accidental injury to the person using the needle during replacement thereof in the storage tube. The finger guard comprises a tubular finger gripping portion having a bore therein in which the storage tube is received. Radially inwardly extending deformable flaps grip the storage tube, whereby differing sizes of storage tube may be accommodated. An annular guard portion extends radially outwardly of the finger grip portion at the forward end of the guard to prevent the needle from contact with the fingers when attempting to insert the needle into the storage tube.
