Abstract
Abstract A two component syringe having two vials each containing a single component. A needle is mounted in the syringe and is arranged to interconnect the vials prior to mixing the contents thereof. One vial is mounted on a holder having a needle hub. The other vial is mounted on an adapter sleeve removably mounted on the needle hub. The adapter sleeve and the other vial are removed after the ingredients have been mixed, leaving the first vial with the associated needle in readiness for injection.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
375 words
A syringe assembly having a solid plastic post with a needle hub at one end of the post and a first part of a coupling at the other end of the post, a double ended needle having one end of the needle projecting from the first coupling part and the other end of the needle projecting out through the hub and the intermediate portion of the needle embedded and anchored in the post, a first vial having a closed end remote from the first coupling part and a cylindrical wall telescoped over the first coupling part and post, a first piston in sliding sealing relation to the cylindrical wall of the first vial, said first piston having a second coupling part, said first and second coupling parts having interlocking means for connecting the parts to stand axial forces in opposite direction whereby after connecting the parts subsequent reciprocation of the first vial relative to the post causes corresponding reciprocation of the first vial relative to the first piston, said first piston having a portion penetrated by said one end of the needle as its said second coupling part is connected with said first coupling part to establish communication between the needle and the first vial, a second vial having a closed end remote from the needle hub and a cylindrical wall and means for removably telescoping said second vial over said other end of the needle, a second piston in sliding sealing relation to the cylindrical wall of the second vial, said second piston having a portion penetrated by said other end of the needle to establish communication between the needle and the second vial as the cylindrical wall of the second vial is telescoped over said other end of the needle, one of said vials containing a first ingredient and the other of the vials containing a second ingredient which may be mixed with the first ingredient by reciprocating the vials after establishing communication between the needle and both vials, a holder fixed to the post having a cylindrical wall surrounding the first vial in telescoping relation, said assembly being conditioned for injection by expelling into the first vial the contents of the second vial and then removing the second vial from the assembly.
Claim 2
Dependent Claim
375 words
A syringe assembly having a solid plastic post with a needle hub at one end of the post and a first part of a coupling at the other end of the post, a double ended needle having one end of the needle projecting from the first coupling part and the other end of the needle projecting out through the hub and the intermediate portion of the needle embedded and anchored in the post, a first vial having a closed end remote from the first coupling part and a cylindrical wall telescoped over the first coupling part and post, a first piston in sliding sealing relation to the cylindrical wall of the first vial, said first piston having a second coupling part, said first and second coupling parts having interlocking means for connecting the parts to stand axial forces in opposite direction whereby after connecting the parts subsequent reciprocation of the first vial relative to the post causes corresponding reciprocation of the first vial relative to the first piston, said first piston having a portion penetrated by said one end of the needle as its said second coupling part is connected with said first coupling part to establish communication between the needle and the first vial, a second vial having a closed end remote from the needle hub and a cylindrical wall and means for removably telescoping said second vial over said other end of the needle, a second piston in sliding sealing relation to the cylindrical wall of the second vial, said second piston having a portion penetrated by said other end of the needle to establish communication between the needle and the second vial as the cylindrical wall of the second vial is telescoped over said other end of the needle, one of said vials containing a first ingredient and the other of the vials containing a second ingredient which may be mixed with the first ingredient by reciprocating the vials after establishing communication between the needle and both vials, a holder fixed to the post having a cylindrical wall surrounding the first vial in telescoping relation, said assembly being conditioned for injection by expelling into the first vial the contents of the second vial and then removing the second vial from the assembly.
Claim 3
Dependent Claim
51 words
The assembly of claim 1 having a sleeve with one end surrounding and telescopically receiving the open end of the first vial and the other end surrounding and telescopically receiving the first coupling part to provide a sliding telescoping seal between the post and the cylindrical wall of the first vial.
Claim 4
Dependent Claim
54 words
The assembly of claim 1 having a sleeve with one end surrounding and telescopically receiving the open end of the second vial and the other end surrounding and telescopically receiving a member associated with the needle hub to provide a sliding telescoping seal between the hub and the cylindrical wall of the second vial.
Claim 5
Dependent Claim
27 words
The assembly of claim 3 in which said member is an intermediate sleeve removably seated on the needle hub and surrounding said other end of the needle.
Claim 6
Dependent Claim
44 words
The assembly of claim 4 in which the intermediate sleeve has a socket adjacent said other end of the needle receiving said portion of the second piston as the cylindrical wall of the second vial is telescoped over said other end of the needle.
Claim 7
Dependent Claim
35 words
The assembly of claim 1 in which one of the coupling parts is a socket and the other of the coupling parts is a projection on the piston adapted to be received in said socket.
