Abstract

A syringe appliance which is uniquely configured so as to enable the user thereof to manipulate the syringe with one hand and wherein the syringe appliance can be used time and again with disposable syrings. The syringe appliance permits positive injection or withdrawal of the inner or piston element of the syringe and is provided with a pistol-like grip to facilitate manipulation.

Claims

1. A manually operated syringe appliance for injecting and withdrawing fluids solely by manually applied forces comprising the combination:

a first, collar-like member having a vertically open wall portion and an upper annular slot to captively receive the outer tube of a syringe in retained relationship therewith;

a second block-like member having opposed lateral grooves and a first opening in the upper portion thereof sufficient in size to accommodate one or more human fingers, the lower portion having a second opening inner-set from said lateral grooves with a retaining slot to transversely receive the inner tube of a syringe in axially retained relationship therewith;

a handle member forming a pistol grip-like configuration; and

a pair of guide members operatively secured in spaced relationship between said first member and said handle member and forming a guide path therebetween, said second, block-like member being slideably mounted on said guide members for operative association between said lateral grooves and said guide members, and being adapted to slideably move between said handle member and said first member solely by the application of manual forces.

2. The syringe appliance in accordance with claim 1 wherein one terminus of said handle member is positioned in aligned relationship to one point on the outer periphery of said collar-like member and the opposite terminus of said handle member extends beyond the periphery of said first collar-like member opposite said one point.

3. The syringe appliance in accordance with claim 2 wherein said first opening of said second, block-like member is oval-shaped.

4. The syringe appliance in accordance with claim 3 wherein said guide members are linear rods.

5. The syringe appliance in accordance with claim 4 wherein the length of said linear rods is sufficient to accommodate the inner tube of the syringe and facilitate grasping of said handle member and said oval-shaped opening of said second, block-like member by the human hand for single hand use of said appliance.
