Abstract
Abstract A one-piece disposable syringe system is disclosed including a conventional syringe having a glass barrel that is prefilled with a measured dose of pharmaceutical and a syringe support and disposal jacket that is adapted to hold the syringe in an injection mode to facilitate the administration of an injection of the pharmaceutical from the barrel and surround the syringe in a disposal mode to form a compact package and thereby facilitate the safe handling and disposal of the syringe while avoiding an accidental needle stick and the possible spread of contagious disease. The syringe support and disposal jacket has lower and upper body members that are rotatably connected together by an integral living hinge. The syringe is coupled to the support and disposal jacket and rotatable from a first position in the injection mode where the upper and lower body members are spaced from one another to a second position in the disposal mode where the lower and upper body members are moved atop one another and locked together with the syringe shielded therebetween.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
335 words
For a syringe including a fluid filled barrel having distal and proximal ends, a needle cannula communicating fluidically with the distal end of the barrel, and a plunger assembly located at the proximal end of the barrel and moving distally therethrough so as to expulse fluid from said barrel via said needle cannula, the improvement of a support and disposal jacket to support said syringe during the administration of an injection and to enclose and shield said syringe at the conclusion of the injection so that said syringe can be safely handled while avoiding an accidental stick from the needle cannula, said support and disposal jacket comprising: a first body member; a second body member; hinge means connecting said first and second body members together so that said body members are rotatable at said hinge means; a cavity formed completely through said first body member for receiving the barrel of said syringe therein; carrier means detachable coupled to the barrel of said syringe in surrounding engagement therewith, said carrier means pivotally connected to said first body member so as to be rotatable in said cavity for causing a corresponding rotation of said barrel in said cavity; and a recess formed in at least one of said first or second body members and sized to receive the barrel of said syringe, said barrel rotatable from a first position extending through the cavity in said first body member in transverse alignment with said first body member at which to administer the injection to a second position in generally parallel alignment with said first body member at the conclusion of the injection, and said first and second body members being aligned with one another to form an angle when the injection is administered or being rotated at said hinge means at the conclusion of the injection until said first and second body members are aligned one atop the other with the barrel of said syringe located therebetween and in the recess of said first or second body members.
Claim 2
Dependent Claim
335 words
For a syringe including a fluid filled barrel having distal and proximal ends, a needle cannula communicating fluidically with the distal end of the barrel, and a plunger assembly located at the proximal end of the barrel and moving distally therethrough so as to expulse fluid from said barrel via said needle cannula, the improvement of a support and disposal jacket to support said syringe during the administration of an injection and to enclose and shield said syringe at the conclusion of the injection so that said syringe can be safely handled while avoiding an accidental stick from the needle cannula, said support and disposal jacket comprising: a first body member; a second body member; hinge means connecting said first and second body members together so that said body members are rotatable at said hinge means; a cavity formed completely through said first body member for receiving the barrel of said syringe therein; carrier means detachable coupled to the barrel of said syringe in surrounding engagement therewith, said carrier means pivotally connected to said first body member so as to be rotatable in said cavity for causing a corresponding rotation of said barrel in said cavity; and a recess formed in at least one of said first or second body members and sized to receive the barrel of said syringe, said barrel rotatable from a first position extending through the cavity in said first body member in transverse alignment with said first body member at which to administer the injection to a second position in generally parallel alignment with said first body member at the conclusion of the injection, and said first and second body members being aligned with one another to form an angle when the injection is administered or being rotated at said hinge means at the conclusion of the injection until said first and second body members are aligned one atop the other with the barrel of said syringe located therebetween and in the recess of said first or second body members.
Claim 3
Dependent Claim
77 words
The support and disposal jacket recited in claim 1, wherein each of said first and second body members has a recess sized to receive the barrel of said syringe, the recesses of said first and second body members cooperating with one another at the conclusion of the injection to receive and enclose said barrel therewithin when said barrel is rotated to said second position and said first and second body members are aligned one atop the other.
Claim 4
Dependent Claim
67 words
The support and disposal jacket recited in claim 1, further comprising a detent slot formed in said carrier means and a detent projecting from said first body member into said cavity, said detent removably received by said detent slot to prevent the displacement of said carrier means and the movement of said barrel when said barrel is at said first position at which to administer the injection.
Claim 5
Dependent Claim
70 words
The support and disposal jacket recited in claim 1, further comprising at least one locking tab extending from said first body member and at least one locking notch formed in said second body member, said locking tab received in said locking notch at the conclusion of the injection when said first and second body members are aligned one atop the other to lock said first and second body members together.
Claim 6
