Biological syringe system

Claim 1

A biological syringe system for delivering a first and second fluid in a mixed composition said biological syringe system including a first and second syringe for holding said first and second fluids, and a corresponding first and second plunger for forcing said first and second fluids from said first and second syringes respectively, comprising: a manifold, said manifold having first and second corresponding component channels therethrough, and first and second input connections respectively communicating with said first and second component channels, said first and second component channels terminating in corresponding exit channels adjacent to each other on an opposing end of said manifold; a discharge assembly coupled to said opposing end of said manifold and receiving fluid from both of said exit channels, said discharge assembly for mixing fluid from both of said exit channels and delivering said mixed fluid in a spray, said discharge assembly having a first and second passage therethrough communicating with said exit channels from said manifold for carrying fluid from said first and second component channels in corresponding first and second passages within said discharge assembly while maintaining said first and second fluids separated from each other, said discharge assembly having a mixing space defined therein to receive separate flows from said passages, said discharge assembly further comprising mixing means disposed within said mixing space to thoroughly mix said first and second fluids for the first time within said mixing space and to immediately thereafter atomize said thoroughly mixed first and second fluids in a spray discharged from said discharge assembly.

Claim 5

A method for applying a tissue adhesive and protective covering which chemically forms and hardens as applied comprising the steps of: providing a first fluid; providing a second fluid which when mixed with said first fluid hardens into said tissue adhesive; forcing said first and second fluids from a corresponding first and second syringe into corresponding first and second passages; partially mixing said first and second fluids together by flowing said fluids under pressure within a cylindrical annular space; and forcing said partially mixed first and second fluids from said cylindrical annular space into a final mixing chamber; thoroughly mixing said first and second fluids in said final mixing chamber; forcing said thoroughly mixed fluids to an axial spray orifice; atomizing said thoroughly mixed first and second fluids by pressured ejection of said fluids through said spray orifice at a predetermined minimum pressure, whereby mixture of said first and second fluids is substantially improved, strength and hardening of said tissue adhesive substantially improved, and wherein thorough mixing occurs just prior to application in atomized form.

Claim 6

A method for applying a tissue adhesive and protective covering which chemically forms and hardens as applied comprising the steps of: providing a first fluid; providing a second fluid which when mixed with said first fluid hardens into said tissue adhesive; forcing said first and second fluids from a corresponding first and second syringe into corresponding first and second passages; partially mixing said first and second fluids together by flowing said fluids under pressure within a cylindrical annular space; and forcing said partially mixed first and second fluids from said cylindrical annular space into a final mixing chamber; thoroughly mixing said first and second fluids in said final mixing chamber; forcing said thoroughly mixed fluids to an axial spray orifice; atomizing said thoroughly mixed first and second fluids by pressured ejection of said fluids through said spray orifice at a predetermined minimum pressure, whereby mixture of said first and second fluids is substantially improved, strength and hardening of said tissue adhesive substantially improved, and wherein thorough mixing occurs just prior to application in atomized form.
