Hypodermic syringe holder with disposable body

Claim 2

An improvement in a hypodermic syringe holder adapted to receive a disposable ampoule comprising: (a) frame portion shaped to receive an ampoule containing a needle hub, (b) a plunger element having a rod, and (c) a holding element, wherein the improvement is that the frame portion: (a) is a disposable hollow cylinder, (b) is adapted to receive the disposable ampoule through an opening at its proximal end, (c) has a head portion at the proximal end thereof and at least one projecting lug on the inside surface of the head portion, wherein the lug positions and frictionally fits with the holding element, and (d) at the lower end has a slot sized to fit around the ampoule's needle hub and to align the ampoule.

Claim 3

An improvement in a hypodermic syringe holder adapted to receive a disposable ampoule comprising: (a) frame portion shaped to receive an ampoule containing a needle hub, (b) a plunger element having a rod, and (c) a holding element, wherein the improvement is that the frame portion: (a) is a disposable hollow cylinder, (b) is adapted to receive the disposable ampoule through an opening at its proximal end, (c) has a head portion of the proximal end thereof and a projecting lug on the inside surface of the head portion, wherein the lug positions and frictionally fits with the holding element, (d) at the lower end has a slot sized to fit around the ampoule's needle hub, (e) has raised ribs located near the upper and lower end, respectively, of the frame portion to align the ampoule, and (f) has a viewing window.

Claim 4

An improvement in a hypodermic syringe holder adapted to receive a disposable ampoule comprising: (a) frame portion shaped to receive an ampoule containing a needle hub, (b) a plunger element having a rod, and (c) a holding element, wherein the improvement is that the frame portion: (a) is a disposable hollow cylinder, (b) is adapted to receive the disposable ampoule through an opening at its proximal end, (c) has a head portion of the proximal end thereof and a projecting lug on the inside surface of the head portion, wherein the lug positions and frictionally fits with the holding element, (d) at the lower end has a slot sized to fit around the ampoule's needle hub, (e) has raised ribs located near the upper and lower end, respectively, of the frame portion to align the ampoule, and (f) has a viewing window.

Claim 5

A hypodermic syringe holder adapted to receive a disposable ampoule comprising: (a) a disposable cylindrical hollow frame portion shaped to receive an ampoule and having a generally cylindrical head portion, said head portion having on its inside surface a projecting lug; (b) an axially movable holding element rotatable about its longitudinal axis within the cylindrical head of said frame portion and engageable with an associated ampoule to securely immobilize the ampoule within the frame portion of the syringe holder, said holding element comprising a barrel portion, a handle portion, a helical groove on the outer surface of said barrel portion, a bore there through, a ramp means for permitting said lug to access said helical groove connecting said helical groove with the distal end surface of said holding element; said barrel portion being sized to rotate and translate within said cylindrical head; (c) a plunger element having a rod portion on its distal end means for engaging a piston of an associated ampoule, said rod portion and piston engaging means being axially and slidably receivable within said bore of said holding element; wherein said helical groove is slidably accessible to said lug through said ramp means and engageable with said lug, whereby said lug secures the holding element to said frame portion such that all of the elements of the syringe holder are in cooperative engagement with on another.

Claim 6

A hypodermic syringe holder adapted to receive a disposable ampoule comprising: (a) a disposable cylindrical hollow frame portion shaped to receive an ampoule and having a generally cylindrical head portion, said head portion having on its inside surface a projecting lug; (b) an axially movable holding element rotatable about its longitudinal axis within the cylindrical head of said frame portion and engageable with an associated ampoule to securely immobilize the ampoule within the frame portion of the syringe holder, said holding element comprising a barrel portion, a handle portion, a helical groove on the outer surface of said barrel portion, a bore there through, a ramp means for permitting said lug to access said helical groove connecting said helical groove with the distal end surface of said holding element; said barrel portion being sized to rotate and translate within said cylindrical head; (c) a plunger element having a rod portion on its distal end means for engaging a piston of an associated ampoule, said rod portion and piston engaging means being axially and slidably receivable within said bore of said holding element; wherein said helical groove is slidably accessible to said lug through said ramp means and engageable with said lug, whereby said lug secures the holding element to said frame portion such that all of the elements of the syringe holder are in cooperative engagement with on another.

Claim 7

The syringe holder of claim 1 wherein said frame portion, said holding element and said plunger element are fabricated of plastic.
