Abstract

A finger grip extension for a syringe is configured to increase the leverage the hand of an operator on the plunger of a syringe during injection of medical fluid into, or withdrawal of medical fluid from a body site. The finger grip extension for a syringe is used with a syringe having a barrel portion having an open proximal end and a distal end for mounting a medical fluid conduit thereon. The open proximal end of the syringe barrel terminates in a rim or flange. The syringe also includes a plunger having a proximal end and a distal end for insertion into the open proximal end of a syringe. The extension grip includes an upwardly extending portion located inside or outside of a syringe barrel. The upwardly extending portion includes a finger support at the uppermost portion thereof.

Claims (11)

1. A removable finger grip extension for a syringe, provided to facilitate use of a syringe during an injection of medical fluid into an injection site, said syringe comprising a barrel portion having an open proximal end and a distal end, said open proximal end terminating in a rim, and a plunger for insertion into the open proximal end of said barrel portion, the plunger having a proximal end and a distal end,

wherein said finger grip comprises a substantially u-shaped structure including a cross member with a circular opening formed therein for encircling an outer surface of a syringe barrel, a seal for securing the grip to the outer surface of the syringe barrel, and adjacent and perpendicular to the circular opening are two opposed arm portions for extending upwardly above the proximal end of the syringe, said arm portions configured to be located on opposite sides of a longitudinal central axis of a syringe barrel and to adjustably extend to a point along the length of the fully or partially extended plunger, and wherein said upwardly extending arm portions further include a finger support at an uppermost portion of each, and

further comprising a plurality of positive lock members located on the outside of the barrel of the syringe, to slidably receive and secure the grip at selected locations along the barrel of the syringe.

2. A finger grip extension in combination with a syringe configured to facilitate the use of the syringe during an injection of medical fluid into an injection site, said combination comprising:

a) a cylindrical syringe barrel having an inside and an outside and

an open proximal end for receiving a plunger, said open proximal end terminating in a rim, said proximal end having a distal surface and a proximal surface; and a distal end for mounting a medical fluid conduit thereon;

b) a plunger being slideably disposed in said syringe barrel;

c) a removable finger grip extension comprising a substantially u-shaped structure including cross member with a circular opening formed therein for encircling an outer surface of a syringe barrel, and adjacent and perpendicular to the circular opening are two opposed arm portions, which extend upwardly above the proximal end of the syringe barrel, said arm portions being located on opposite sides of a longitudinal central axis of the syringe barrel, and said arm portions adjustably extend to a point along the length of a fully or partially extended plunger, and wherein said upwardly extending arm portions further include an integral finger support located at an uppermost portion of each; and

d) a plurality of positive lock members located on the outside of the barrel of the syringe, to slidably receive and secure the grip at selected locations along the outside of the barrel of the syringe.

3. The finger grip combination of claim 2 , further comprising a seal having a circular opening formed therein, wherein the seal is attached to a lower surface of the cross member and the seal opening is of a diameter substantially equal to an outside diameter of the syringe barrel and the seal secures the grip to the barrel of the syringe when the grip is placed over the barrel of the syringe.

4. The finger grip combination of claim 2 wherein the syringe barrel fluid capacity is from 50 to 500 ml.
