A clinicians hand support structure provides an ergometric grasp of a syringe housing, the support structure includes a surrounding sidewall about a longitudinal axis, the sidewall having first and second end portions, the sidewall also having an outer surface and an inner surface that defines a sidewall interior. Further, the inner surface having a portion with a frustroconical shape that is smaller adjacent to the first end portion and larger adjacent to the second end portion. Also, the sidewall has an elongated aperture therethrough, wherein the sidewall inner surface partially creates a frictional encasement of the syringe housing. Further, included is an extension element having a proximal and distal portion wherein the extension element is positioned to extend radially outward from the longitudinal axis, operationally the distal portion nests in a palm of a clinicians hand and the sidewall outer surface is grasped by a finger of the clinician.
