Abstract
Abstract A prefilled syringe with a permanent cylindrical needle guard extending beyond the tip of the needle is disclosed. The needle guard is integral with the syringe holder so as to provide no exposure, selective or otherwise, of the needle. A removable needle guard is further provided. A tubing set is provided with a puncture port which fits in a liquid-tight manner into the cylindrical needle guard. The tubing set further includes anti-siphoning means and low volume tubing.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
199 words
An apparatus comprising: a syringe including a needle a barrel, and a plunger axially slidable within said barrel; a syringe holder engaging substantially an entire longitudinal length of said barrel of said syringe; a substantially cylindrical needle guard extending from said syringe beyond the tip of said needle and having an interior diameter and an exterior diameter, said needle guard being formed integrally with said syringe holder; a tubing set including a puncture port means insertable within said needle guard, tubing leading from said puncture port means, an annular hub serving as a manual grip for the tubing set, and a tamper-resistant disk extends radially from the annular hub for forming a mechanical interface with surfaces of a syringe pump to cooperate in preventing tampering; and wherein upon gripping said annular hub and interposing and guiding the needle guard between the puncture port means and the annular hub, to thereby engage said puncture of the puncture port means by the needle thereby fluid will then be permitted to be injected from said syringe through said needle and through said tubing set, said puncture port means being removable from said tubing set in order to expose a first lock connector.
Claim 2
Independent Claim
199 words
An apparatus comprising: a syringe including a needle a barrel, and a plunger axially slidable within said barrel; a syringe holder engaging substantially an entire longitudinal length of said barrel of said syringe; a substantially cylindrical needle guard extending from said syringe beyond the tip of said needle and having an interior diameter and an exterior diameter, said needle guard being formed integrally with said syringe holder; a tubing set including a puncture port means insertable within said needle guard, tubing leading from said puncture port means, an annular hub serving as a manual grip for the tubing set, and a tamper-resistant disk extends radially from the annular hub for forming a mechanical interface with surfaces of a syringe pump to cooperate in preventing tampering; and wherein upon gripping said annular hub and interposing and guiding the needle guard between the puncture port means and the annular hub, to thereby engage said puncture of the puncture port means by the needle thereby fluid will then be permitted to be injected from said syringe through said needle and through said tubing set, said puncture port means being removable from said tubing set in order to expose a first lock connector.
Claim 3
Dependent Claim
19 words
The apparatus of claim 1 wherein said tubing leads from said puncture port means to a second lock connector.
Claim 4
Dependent Claim
20 words
The apparatus of claim 1 wherein said tubing set includes anti-siphoning means between said puncture port means and said tubing.
Claim 5
Dependent Claim
10 words
The apparatus of claim 1 wherein said syringe is prefilled.
Claim 6
Independent Claim
221 words
An apparatus comprising: a syringe including a needle barrel, and a plunger axially slidable within said barrel; a syringe holder engaging substantially an entire longitudinal length of said barrel of said syringe; a substantially cylindrical needle guard extending from said syringe beyond the tip of said needle and having an interior diameter and an exterior diameter, said needle guard being formed integrally with said syringe holder; a tubing set including a puncture port means insertable within said needle guard, tubing leading from said puncture port means, an annular hub serving as a manual grip for the tubing set, and a tamper-resistant disk extends radially from the annular hub for forming a mechanical interface with surfaces of a syringe pump to cooperate in preventing tampering; and wherein upon gripping said annular hub and interposing and guiding the needle guard between the puncture port means and the annular hub, to thereby engage said puncture port means within said needle and then upon puncture of the puncture port means by the needle thereby fluid will then be permitted to be injected from said syringe through said needle and through said tubing set, said tubing set including anti-siphoning means between said puncture port means and said tubing, said puncture port means being removable from said anti-siphoning means in order to expose a first lock connector.
Claim 7
Independent Claim
221 words
An apparatus comprising: a syringe including a needle barrel, and a plunger axially slidable within said barrel; a syringe holder engaging substantially an entire longitudinal length of said barrel of said syringe; a substantially cylindrical needle guard extending from said syringe beyond the tip of said needle and having an interior diameter and an exterior diameter, said needle guard being formed integrally with said syringe holder; a tubing set including a puncture port means insertable within said needle guard, tubing leading from said puncture port means, an annular hub serving as a manual grip for the tubing set, and a tamper-resistant disk extends radially from the annular hub for forming a mechanical interface with surfaces of a syringe pump to cooperate in preventing tampering; and wherein upon gripping said annular hub and interposing and guiding the needle guard between the puncture port means and the annular hub, to thereby engage said puncture port means within said needle and then upon puncture of the puncture port means by the needle thereby fluid will then be permitted to be injected from said syringe through said needle and through said tubing set, said tubing set including anti-siphoning means between said puncture port means and said tubing, said puncture port means being removable from said anti-siphoning means in order to expose a first lock connector.
Claim 8
Dependent Claim
18 words
The apparatus of claim 5 wherein said tubing leads from said anti-siphoning means to a second lock connector.
