Abstract
Abstract A spray syringe is disclosed which includes in combination a hypodermic syringe and a tubular member having a spray orifice at a distal tip. The tubular member is flexible permitting orientation of the spray orifice independent of the orientation of the syringe. The tubular member is sized such that the needle of the syringe is received within the bore in a fluid tight seal.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
50 words
A spray syringe comprising, in combination, a hypodermic syringe having a luer fitting and a tubular member terminating in a liquid spray orifice, means for attaching said tubular member directly to said fitting and said tubular member includes a flexible conduit section between said fitting and said liquid spray orifice.
Claim 2
Dependent Claim
50 words
A spray syringe comprising, in combination, a hypodermic syringe having a luer fitting and a tubular member terminating in a liquid spray orifice, means for attaching said tubular member directly to said fitting and said tubular member includes a flexible conduit section between said fitting and said liquid spray orifice.
Claim 3
Dependent Claim
84 words
A spray syringe comprising, in combination, a hypodermic syringe having a hypodermic needle secured thereto, a tubular member enclosing said hypodermic needle and terminating in a liquid spray orifice, and means for securing said tubular member to said hypodermic needle and wherein said tubular member has an inside bore sized to engage the hypodermic needle adjacent the tip thereof in a fluid tight seal, whereby liquid discharged from the tip of said needle is prevented from flowing between said needle and said tubular member.
Claim 4
Dependent Claim
84 words
A spray syringe comprising, in combination, a hypodermic syringe having a hypodermic needle secured thereto, a tubular member enclosing said hypodermic needle and terminating in a liquid spray orifice, and means for securing said tubular member to said hypodermic needle and wherein said tubular member has an inside bore sized to engage the hypodermic needle adjacent the tip thereof in a fluid tight seal, whereby liquid discharged from the tip of said needle is prevented from flowing between said needle and said tubular member.
Claim 5
Dependent Claim
26 words
A spray syringe of claim 2 wherein said tubular member includes a flexible conduit section intermediate the tip of said hypodermic needle and said spray orifice.
Claim 6
Dependent Claim
63 words
A spray nozzle for use with a hypodermic syringe having a hypodermic needle attached thereto, said spray nozzle comprising an elongated tubular member adapted to enclose said hypodermic needle and engage said hypodermic needle in a fluid tight seal adjacent the tip of said needle, said tubular member extending beyond the tip of said hypodermic needle and terminating in a liquid spray orifice.
Claim 7
Dependent Claim
63 words
A spray nozzle for use with a hypodermic syringe having a hypodermic needle attached thereto, said spray nozzle comprising an elongated tubular member adapted to enclose said hypodermic needle and engage said hypodermic needle in a fluid tight seal adjacent the tip of said needle, said tubular member extending beyond the tip of said hypodermic needle and terminating in a liquid spray orifice.
Claim 8
Dependent Claim
26 words
A spray nozzle of claim 4 wherein said tubular member includes a flexible conduit section intermediate the tip of said hypodermic needle and said spray orifice.
