Abstract
A combination accessory finger flange and pharmaceutical syringe system including a needle safety shield having a safety-shield outer tube the proximal end of which forms a coupling ring, has a base portion with diametrically-opposed finger flanges that extend radially outwardly therefrom and a central opening dimensioned to receive the safety-shield outer tube. Diametrically-opposed, radially outwardly extending coupling-ring flanges are received and retained in diametrically-opposed receptacles on a top surface of the base-portion adjacent the central opening when the safety-shield outer tube is in the central opening, the coupling-ring flanges are in contact with the top surface of the base-portion and the coupling ring is rotated in a first rotational direction relative to the base portion.

6. A combination accessory finger flange and pharmaceutical syringe system comprising:
-
a needle safety shield having a safety-shield outer tube with a syringe barrel disposed therein, a proximal end of the safety-shield outer tube forming a coupling ring connecting the proximal end of the syringe barrel to the safety-shield outer tube, the coupling ring having diametrically-opposed, radially outwardly extending coupling-ring flanges; an accessory finger flange including a base portion having a central opening dimensioned to receive the safety-shield outer tube therein, the base portion including a base-portion top surface and a base-portion bottom surface, diametrically-opposed receptacles positioned on the base-portion top surface adjacent the central opening, the receptacles receiving and retaining the coupling-ring flanges therein such that in a first position the coupling-ring flanges are in contact with the base-portion top surface and extend beyond an edge of the top surface and in a second position such that when the coupling ring is rotated in a first rotational direction relative to the base portion, the coupling-ring flanges are received in the receptacles and do not extend beyond an edge of the top surface.
