Abstract

Abstract A dual hypodermic syringe device utilizing a pair of laterally spaced barrels with an interconnecting portion occupying the space between the barrels. The interconnecting portion extends for a substantial portion of the length of the barrels. The barrels are disposed in essentially parallel relationship, and a needle is associated with each barrel. The barrels and interconnecting portion are made from a common piece of material, and in each barrel a movable plunger is disposed. The spacing of the needles is less than 68 mm. such that an injection may be given to a patient that involves only a single sensation of pain.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 132 words
A dual hypodermic syringe device comprising a pair of laterally spaced barrels with an interconnecting portion occupying the space between said barrels and extending for a substantial portion of the length of the barrels, said barrels adapted to contain fluid said barrels and said interconnecting portion constructed from a single piece of material, an independent plunger provided in each of said barrels, said barrels having means thereon upon which a pair of needles can be operatively disposed in essentially parallel, spaced relationship and extend in the same direction, said barrels forming an integral unit and being spaced apart a distance such that the needles, when in the operative position, are spaced apart less than 68 mm., whereby an injection can be given to a patient involving only a single sensation of pain.
Claim 2
Dependent Claim 132 words
A dual hypodermic syringe device comprising a pair of laterally spaced barrels with an interconnecting portion occupying the space between said barrels and extending for a substantial portion of the length of the barrels, said barrels adapted to contain fluid said barrels and said interconnecting portion constructed from a single piece of material, an independent plunger provided in each of said barrels, said barrels having means thereon upon which a pair of needles can be operatively disposed in essentially parallel, spaced relationship and extend in the same direction, said barrels forming an integral unit and being spaced apart a distance such that the needles, when in the operative position, are spaced apart less than 68 mm., whereby an injection can be given to a patient involving only a single sensation of pain.
Claim 3
Dependent Claim 20 words
The dual hypodermic syringe arrangement as defined in claim 1 in which said neeDles are approximately of the same length.
Claim 4
Dependent Claim 32 words
The dual hypodermic syringe arrangement as defined in claim 2 in which said needles are of different styles, such that one needle injects into a deeper layer of flesh than the other.
Claim 5
Dependent Claim 30 words
The dual hypodermic syringe arrangement as defined in claim 1 in which said needles are of different lengths, thus enabling injections to be made to different depths in a patient.
