Abstract
Abstract A flexible needle and guard device for a hypodermic syringe substantially reducing the bending and breaking of needles when an innoculation is administered. The device including a flexure tube interconnected between the syringe and the needle thus permitting the needle to pivot laterally, and a guard mounted on the syringe and over the needle, wherein the guard has a spring disposed therein to bias the needle in axial alignment with the syringe.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
185 words
A flexible needle and guard device for a hypodermic syringe having a barrel for holding an innoculant, a nozzle connected to said barrel through which said innoculant is ejected, and a plunger slidably disposed in said barrel for ejecting said innoculant; said flexible needle and guard device comprising: an elongated hollow connector secured on one end to said nozzle and having the other end thereof projecting axially of said nozzle; a flexible tube having one end secured to said other end of said connector and having a second end projecting axially of said connector; an elongated hollow needle retainer secured on one end to said second end of said tube and having the other end projecting axially of said tube, said retainer spaced from said connector; a hollow needle detachably secured to said other end of said retainer and coaxially aligned in one position with said connector wherein said needle is pivotable from said one position to another position angularly inclined to said connector; and a first biasing means operably connected between said barrel and said needle for biasing said needle to said one position.
Claim 2
Dependent Claim
185 words
A flexible needle and guard device for a hypodermic syringe having a barrel for holding an innoculant, a nozzle connected to said barrel through which said innoculant is ejected, and a plunger slidably disposed in said barrel for ejecting said innoculant; said flexible needle and guard device comprising: an elongated hollow connector secured on one end to said nozzle and having the other end thereof projecting axially of said nozzle; a flexible tube having one end secured to said other end of said connector and having a second end projecting axially of said connector; an elongated hollow needle retainer secured on one end to said second end of said tube and having the other end projecting axially of said tube, said retainer spaced from said connector; a hollow needle detachably secured to said other end of said retainer and coaxially aligned in one position with said connector wherein said needle is pivotable from said one position to another position angularly inclined to said connector; and a first biasing means operably connected between said barrel and said needle for biasing said needle to said one position.
Claim 3
Dependent Claim
77 words
A flexible needle and guard device for a hypodermic syringe as defined in claim 1 including a guard tube having one end thereof slidably mounted on said barrel, having the other end thereof projecting axially of said barrel, and having said first biasing means mounted therein; said guard tube being movable from a first position substantially encompassing said needle to a second position wherein a portion of said needle projects outwardly from said guard tube other end.
Claim 4
Dependent Claim
31 words
A flexible needle and guard device for a hypodermic syringe as defined in claim 2 wherein said first biasing means is a conical shaped helical spring through which said needle projects.
Claim 5
Dependent Claim
55 words
A flexible needle and guard device for a hypodermic syringe as defined in claim 2 including a second biasing means which is mounted in said guard tube and is coactable with said barrel, wherein said guard tube is moveable from said first position to said second position against the bias of said second biasing means.
Claim 6
Dependent Claim
54 words
A flexible needle and guard device for a hypodermic syringe as defined in claim 4 wherein said second biasing means is a helical spring having one end disposed against said barrel and having the other end connected to said conical spring, and including a collar connected to said springs and to said guard tube.
Claim 7
Dependent Claim
30 words
A flexible needle and guard device for a hypodermic syringe as defined in claim 5 including a holding means secured to said guard tube and operably connected to said barrel.
Claim 8
Dependent Claim
30 words
A flexible needle and guard device for a hypodermic syringe as defined in claim 6 wherein said guard tube other end is rolled inwardly to provide a smooth peripheral edge.
Claim 9
Dependent Claim
40 words
A flexible needle and guard device for a hypodermic Syringe as defined in claim 6 wherein said holding means is a leaf spring having one end secured to said guard tube and having a free end frictionally engaging said barrel.
Claim 10
Dependent Claim
35 words
A flexible needle and guard device for a hypodermic syringe as defined in claim 8 wherein said guard tube has a slot formed in the wall thereof and said leaf spring free end projects therethrough.
Claim 11
Dependent Claim
30 words
A flexible needle and guard device for a hypodermic syringe as defined in claim 9 wherein said guard tube other end is rolled inwardly to provide a smoother peripheral edge.
