Abstract
A conventional syringe defines a longitudinal axis and includes a syringe barrel having a syringe barrel flange laterally extending from an open proximal end of the syringe barrel and a plunger advanceable into the syringe barrel. A rotatable finger flange for such a syringe includes identical first and second flange components, each having an attachment member configured to releasably engage the syringe barrel flange and/or the other flange component, and a flange member laterally extending therefrom. The first and second flange component are engageable and rotatable relative to one another about the longitudinal axis between a non-use position, wherein the first flange member overlies the second flange member to reduce the finger flange footprint, and a use position, wherein the first flange member and the second flange member are angularly spaced apart from one another to provide a finger flange having a greater lateral extent than the syringe barrel flange.
