Syringe holder

Claim 2

In combination with a syringe having a plunger slidably received in a barrel, and wherein the barrel has an open end and a needle end, with a finger engageable flange at the open end and an annular flange surrounding a needle in the needle end, a syringe holder comprising a generally tubular housing having a length corresponding to the combined length of the syringe barrel and needle and having an internal cavity adapted to receive the syringe barrel, said housing having an open end through which the syringe barrel is adapted to be inserted, said housing also having a needle end opposite said open end thereof, said needle end defining an opening for receiving the syringe needle, biasing means inside said housing cavity for acting on the syringe barrel to urge it and the needle toward a first position such that the needle is retracted inside the housing, means defined by said housing adjacent the open end of said housing for cooperating with the finger engageable flange at the open end of the syringe barrel to releasably secure the syringe barrel in the housing in a second position such that the needle projects from the housing, and a resilient plastic chip having an axial length corresponding generally to the axial displacement of said syringe barrel relative to said housing corresponding to said first and second positions, said clip having one portion and an opposite end portion, said one portion cooperating with said housing defined means at the open end of said housing and the opposite end portion cooperating with the finger engageable flange at the open end of said syringe barrel to secure the barrel to said housing in said first position.

Claim 3

The combination of claim 1 wherein said plastic clip is removably receivable on said housing for ready access to so secure said housing and syringe barrel after an injection.

Claim 4

The contribution of claim 1 wherein said means defined by said housing adjacent the open end of said housing for cooperating with the finger engageable flange normally defined by the syringe barrel more particularly comprises a projecting flange integrally defined by said housing and including diametrically opposed finger engageable portions similar to those normally defined by the syringe barrel, and at least one of said housing defined flange portions including an outer edge portion defining a slot for receiving one of the syringe barrel finger engageable flange portions, said housing and the syringe barrel being rotatable with respect to one another to permit said slot to releasably receive the syringe barrel flange portion.

Claim 5

The combination of claim 3 further characterized by means for securing the syringe barrel in said first position.

Claim 6

The combination comprising a syringe and a holder for said syringe, said syringe comprising a plunger, a barrel for slidably receiving said plunger, said barrel having an open end and a needle end defining an annular flange, a needle mounted in said needle end and projecting axially outwardly of said barrel, said barrel having finger engageable flanges adjacent said barrel open end, said holder comprising a generally tubular housing having a length corresponding to the combined length of the syringe barrel and needle and having an internal cavity adapted to receive the syringe barrel, said housing having an open end through which the syringe barrel is adapted to be inserted, said housing also having a needle end opposite said open end thereof, said needle end defining an opening for receiving the syringe needle, biasing means inside said housing cavity for acting on the syringe barrel to urge it and the needle toward a first position such that the needle is retracted inside the housing, means defined by said housing adjacent the open end of said housing for cooperating with the finger engageable flange at the open end of the syringe barrel to releasably secure the syringe barrel in the housing in a second position such that the needle projects from the housing, and a resilient plastic clip having an axial length corresponding generally to the axial displacement between said syringe barrel and said housing corresponding to said first and second positions, said clip having one portion and an opposite end portion, said one portion cooperating with said housing defined means at the open end of the housing and the opposite end portion cooperating with the finger engageable flange at the open end of the syringe barrel to secure the barrel to said housing in said first position.

Claim 7

The combination comprising a syringe and a holder for said syringe, said syringe comprising a plunger, a barrel for slidably receiving said plunger, said barrel having an open end and a needle end defining an annular flange, a needle mounted in said needle end and projecting axially outwardly of said barrel, said barrel having finger engageable flanges adjacent said barrel open end, said holder comprising a generally tubular housing having a length corresponding to the combined length of the syringe barrel and needle and having an internal cavity adapted to receive the syringe barrel, said housing having an open end through which the syringe barrel is adapted to be inserted, said housing also having a needle end opposite said open end thereof, said needle end defining an opening for receiving the syringe needle, biasing means inside said housing cavity for acting on the syringe barrel to urge it and the needle toward a first position such that the needle is retracted inside the housing, means defined by said housing adjacent the open end of said housing for cooperating with the finger engageable flange at the open end of the syringe barrel to releasably secure the syringe barrel in the housing in a second position such that the needle projects from the housing, and a resilient plastic clip having an axial length corresponding generally to the axial displacement between said syringe barrel and said housing corresponding to said first and second positions, said clip having one portion and an opposite end portion, said one portion cooperating with said housing defined means at the open end of the housing and the opposite end portion cooperating with the finger engageable flange at the open end of the syringe barrel to secure the barrel to said housing in said first position.

Claim 8

The contribution of claim 5 wherein said plastic clip is removably receivable on said housing for ready access to so secure said housing and syringe barrel after an injection.

Claim 9

The contribution of claim 5 wherein said means defined by said housing adjacent the open end of said housing for cooperating with the finger engageable flange normally defined by the syringe barrel more particularly comprises a projecting flange integrally defined by said housing and including diametrically opposed finger engageable portions similar to those normally defined by the syringe barrel, and at least one of said housing defined flange portions including an outer edge portion defining a slot for receiving one of the syringe barrel finger engageable flange portions, said housing and the syringe barrel being rotatable with respect to one another to permit said slot to releasably receive the syringe barrel flange portion.

Claim 10

The combination of claim 7 wherein said resilient plastic clip has an axial length corresponding generally to the axial displacement between said first and second positions, and said clip having portions adjacent its respective ends cooperating with said housing defined means at the open end of said housing and with the finger engageable flange at the open end of the syringe barrel respectively to secure the barrel to said housing in said first position.
