Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
265 words
A hypodermic syringe holder and injector device for holding a syringe having a hollow barrel, a cap mounted on one end of the barrel, a piston disposed in the barrel and connected to a piston rod which projects outwardly through the cap, and a needle secured to the other end of the barrel, the device comprising: an elongated hollow open ended barrel having an enlarged portion formed therein proximate one end thereof wherein said barrel between said enlarged portion and said one end has a greater diameter than said barrel other end; handle means having one end thereof slidably mounted in said barrel other end and having the other end thereof projecting rearwardly of said barrel; syringe holding means having one end thereof mounted in said barrel one end and having the other end thereof projecting forwardly of said barrel other end, wherein the syringe cap seats in said barrel one end between said enlarged portion and said syringe holding means one end, and the syringe barrel is disposed in said syringe holding means; and a hollow needle guard having one end slidably mounted in said syringe holding means other end and having the other end thereof projecting forwardly of said syringe holding means other end; wherein said handle means is slidable in said barrel from a first position near said barrel other end to a second position proximate said enlarged portion, and said guard is slidable from a first position wherein the syringe needle is disposed in said guard to a second position wherein the needle substantially projects forwardly of said guard other end.
Claim 2
Dependent Claim
265 words
A hypodermic syringe holder and injector device for holding a syringe having a hollow barrel, a cap mounted on one end of the barrel, a piston disposed in the barrel and connected to a piston rod which projects outwardly through the cap, and a needle secured to the other end of the barrel, the device comprising: an elongated hollow open ended barrel having an enlarged portion formed therein proximate one end thereof wherein said barrel between said enlarged portion and said one end has a greater diameter than said barrel other end; handle means having one end thereof slidably mounted in said barrel other end and having the other end thereof projecting rearwardly of said barrel; syringe holding means having one end thereof mounted in said barrel one end and having the other end thereof projecting forwardly of said barrel other end, wherein the syringe cap seats in said barrel one end between said enlarged portion and said syringe holding means one end, and the syringe barrel is disposed in said syringe holding means; and a hollow needle guard having one end slidably mounted in said syringe holding means other end and having the other end thereof projecting forwardly of said syringe holding means other end; wherein said handle means is slidable in said barrel from a first position near said barrel other end to a second position proximate said enlarged portion, and said guard is slidable from a first position wherein the syringe needle is disposed in said guard to a second position wherein the needle substantially projects forwardly of said guard other end.
Claim 3
Dependent Claim
66 words
A hypodermic syringe holder and injector device as defined in claim 1 wherein said handle means one end has a first stub secured to the periphery thereof which projects radially therefrom and said barrel has an elongated slot formed longitudinally through the side wall thereof for slidably receiving said stub, wherein the ends of said slot limit the movement of said handle means in said barrel.
Claim 4
Dependent Claim
36 words
A hypodermic syringe holder and injector device as defined in claim 1 wherein a releasable locking means is operably connected between said guard and said syringe holding means to lock said guard in said first position.
Claim 5
Dependent Claim
117 words
A hypodermic syringe holder and injector device as defined in Claim 3 wherein said locking means comprises a guard stub secured to the periphery of said guard and projecting outwardly therefrom, and a hook-ended slot formed longitudinally through the sidewall of said syringe holding means; said hook-ended slot provided to receive said guard stub therein, wherein said slot hook end slidably receives said guard stub in said first position, and upon rotating said guard in said syringe holding means said guard stub will be free to slide along said slot thus peRmitting said guard to slide to said second position when opposing forces are exerted in said guard other end and said syringe holding means other end.
Claim 6
Dependent Claim
88 words
A hypodermic syringe holder and injector device as defined in claim 2 wherein said handle means includes an outer hollow handle having a plug disposed in one end thereof and having said first stub secured to the periphery of said outer handle one end and projecting outwardly therefrom, an inner handle telescopically mounted in said outer handle, and stop means operably interconnecting said inner and said outer handles wherein said inner handle can be disposed in any of a plurality of predetermined positions relative to said outer handle.
Claim 7
Dependent Claim
134 words
A hypodermic syringe holder and injector device as defined in claim 5 wherein a releasable locking means is operably connected between said guard and said syringe holding means to lock said guard in said first position, said locking means comprising a guard stub secured to the periphery of said guard and projecting outwardly therefrom and a hook-ended slot formed longitudinally through the sidewall of said syringe holding means to receive said guard stub, wherein the hook end thereof receives said guard stub in said first position and upon rotating said guard in said syringe holding means said guard stub will be free to slide along said slot thus permitting said guard to slide to said second position when opposing forces are exerted on said guard other end and said syringe holding means other end.
