Abstract: A syringe grip assembly configured to receive a syringe barrel comprises a plunger rod, a syringe grip, and an engagement member. The plunger rod has a ribbed outer surface. The syringe grip includes an activation button segment, and a central opening. The central opening extends through the syringe grip and is configured to receive the plunger rod. The engagement member includes a rod engagement segment that is arranged at a non-normal angle with respect to a central axis of the plunger rod. The engagement member is selectively moveable using the activation button segment between (i) an engaged position, in which the rod engagement segment is in contact with the plunger rod, and (ii) a disengaged position, in which the rod engagement segment is separated from the plunger rod.

Abstract: A syringe (1) is provided with a tube (2), a plunger rod (3), and a plunger rod head (4). The plunger rod head (4) has a first surface (41) and a second surface (42). A finger grip component (5) is provided as a one-piece body attached to the tube (2), and includes an injection finger support surface (61) arched in a direction perpendicular to the longitudinal axis (A) with a first curvature for co-operative association with the first surface (41), and an aspiration finger support surface (62) arched in a direction perpendicular to the longitudinal axis (A) with a second curvature for co-operative association with the second surface (42).
