Abstract
Abstract A multiplicity of vials containing the same vaccine or medicament are connected together in series and a pressure source is connected to the first vial to apply above ambient pressure to it and to the remaining vials, the last vial in the series being used by medical personnel to fill syringes.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
172 words
In a dispensing system for liquid vaccine and medicaments contained in conventional vials for supplying liquid to syringes inserted into the vials, a support board, a series of vial clamps supported on said board, a series of vials containing said liquid in said clamps and disposed so that the vials are upside down with the liquid resting on the penetratable self sealing membrane in the vial, there being a first vial in said series and a last vial in said series and a multiplicity of vials in said series between said first and last, conduits operatively interconnecting said vials for the continuous flow of liquid from one vial to the adjacent vial and the direction of flow being from the first vial toward the last vial, and a source of low fluid pressure operatively connected to said first vial to apply a low fluid pressure to said liquid in all said vials and pressurize flow toward the last vial whereby the last vial is continuously supplied with liquid from the remaining vials.
Claim 2
Dependent Claim
172 words
In a dispensing system for liquid vaccine and medicaments contained in conventional vials for supplying liquid to syringes inserted into the vials, a support board, a series of vial clamps supported on said board, a series of vials containing said liquid in said clamps and disposed so that the vials are upside down with the liquid resting on the penetratable self sealing membrane in the vial, there being a first vial in said series and a last vial in said series and a multiplicity of vials in said series between said first and last, conduits operatively interconnecting said vials for the continuous flow of liquid from one vial to the adjacent vial and the direction of flow being from the first vial toward the last vial, and a source of low fluid pressure operatively connected to said first vial to apply a low fluid pressure to said liquid in all said vials and pressurize flow toward the last vial whereby the last vial is continuously supplied with liquid from the remaining vials.
Claim 3
Dependent Claim
73 words
A system as set forth in claim 1 wherein substantially each of said conduits has a relatively short hollow syringe-type needle at one end inserted into a vial to form an inlet for liquid to flow from the vial into the conduit and a relatively long hollow syringe-type needle at the other end inserted into the adjacent vial to form an outlet for liquid to flow from the conduit into the adjacent vial.
Claim 4
Independent Claim
150 words
The method of increasing the efficiency with which syringes are filled with liquid vaccine or medicament which comprises arranging a multiplicity of conventional vials containing said liquid so that the vials are upside down with the liquid resting on the penetratable self sealing membrane in the vial, inserting syringe-type needles through the membrane, attaching tubing to said needles and interconnecting said vials in series relationship so that liquid flows in series from one vial to the adjacent vial in a direction from the first to the last of the vials in the series, supplying a fluid at a pressure slightly above ambient to the first in said series of vials to thereby pressurize the liquid in the vial-conduit system, and withdrawing liquid from the last of the vials by insertion of a syringe into the last of said vials to fill said syringe with a desired amount of said liquid.
Claim 5
Independent Claim
150 words
The method of increasing the efficiency with which syringes are filled with liquid vaccine or medicament which comprises arranging a multiplicity of conventional vials containing said liquid so that the vials are upside down with the liquid resting on the penetratable self sealing membrane in the vial, inserting syringe-type needles through the membrane, attaching tubing to said needles and interconnecting said vials in series relationship so that liquid flows in series from one vial to the adjacent vial in a direction from the first to the last of the vials in the series, supplying a fluid at a pressure slightly above ambient to the first in said series of vials to thereby pressurize the liquid in the vial-conduit system, and withdrawing liquid from the last of the vials by insertion of a syringe into the last of said vials to fill said syringe with a desired amount of said liquid.
Claim 6
Dependent Claim
34 words
A method as set forth in claim 3 including a final step of placing the syringes as they are filled on a storage rack for subsequent use to inject said liquid into living tissue.
