At least one smaller fluid or solid containing container will be added inside the flush housing and will separate its content(s) from other fluids or solids inside the flush housing. The shape of the housing and inner containers can be similar with the outer syringe flush with channels to facilitate the flow of fluids and they can also be of different shapes which will automatically create channels to allow the flow of fluid. An opening in the syringe plunger configured to receive a medicine vial. ## Claims ### Claim 1 A syringe, comprising: a plunger having a shaft, said shaft of said plunger having a flange located opposite a sealing structure, said sealing structure having a first side located opposite a second side, said first side of said sealing structure having a first piercing element, said second side of said sealing structure connected to said shaft of said plunger; a barrel, said barrel having a chamber receiving said sealing structure of said plunger; and, a first container, said first container is retained within said barrel, said first container retaining a substance, said first container is configured to be punctured by said first piercing element when a user depresses said plunger within said barrel of said syringe; wherein said first container includes at least one longitudinal channel located on an outer wall surface of said first container to allow for the substance to move along the outer surface from a proximal end to a distal end of the first container. ### Claim 2 (depends on 1) The syringe of claim 1, wherein said first container is collapsible. ### Claim 3 (depends on 1) The syringe of claim 1, wherein said plunger having at least one recess retaining an alcohol pad. ### Claim 4 (depends on 3) The syringe of claim 3, wherein said at least one recess of said plunger having a removable lid. ### Claim 5 (depends on 1) The syringe of claim 1, wherein said barrel of said syringe retaining a second container, said second container retaining a substance, said second container is configured to be punctured by said first piercing element when a user depresses said plunger within said barrel of said syringe. ### Claim 6 (depends on 1) The syringe of claim 1, wherein said shaft of said plunger having a loading chamber, said loading chamber receiving a vessel retaining a substance. ### Claim 7 (depends on 6) The syringe of claim 6, wherein said loading chamber of said plunger having an inner wall surface having at least one protruding structure, said at least one protruding structure is configured to engage said vessel and secure said vessel within said loading chamber. ### Claim 8 (depends on 6) The syringe of claim 6, wherein said second side of said sealing structure having at least one support structure, said at least one support structure is configured to engage said vessel and secure said vessel within said loading chamber. ### Claim 9 (depends on 6) The syringe of claim 6, wherein said second side of said sealing structure having a second piercing element, said second piercing element is configured to puncture at least a portion of said vessel to release said substance from said vessel when a user depresses said vessel into said loading chamber of said plunger, said second piercing element having at least one opening, said at least one opening of said second piercing element is connected to a conduit, said conduit traversing through said sealing structure of said plunger to said barrel of said syringe, said conduit is configured to be oriented in a closed orientation to prevent said substance from flowing from said plunger to said barrel of said syringe, said conduit is configured to be oriented in an open orientation to allow said substance to flow from said plunger to said barrel of said syringe. ### Claim 10 (depends on 9) The syringe of claim 9, wherein said second piercing element having at least one flange. ### Claim 11 (depends on 6) The syringe of claim 6, wherein said sealing structure having a first cylindrical structure having a first bore and a second bore, said sealing structure having a second cylindrical structure having a third bore and a fourth bore, said second side of said sealing structure having a second piercing element, said second piercing element configured to puncture at least a portion of said vessel to release said substance from said vessel when a user depresses said vessel into said loading chamber of said plunger, said second piercing element having at least one opening, said at least one opening of said second piercing element is connected to said first bore and said second bore of said first cylindrical structure, said first bore and said second bore of said first cylindrical structure are oriented in an open configuration to align with said third bore and said fourth bore of said second cylindrical structure to allow said substance to flow from said vessel of said plunger to said barrel of said syringe. ### Claim 12 (depends on 11) The syringe of claim 11, wherein said second piercing element having at least one flange. ### Claim 13 A syringe, comprising: a plunger having a shaft, said shaft of said plunger having a flange located opposite a sealing structure, said sealing structure having a first side located opposite a second side, said first side of said sealing structure having a first piercing element, said second side of said sealing structure connected to said shaft of said plunger; a barrel, said barrel having a chamber receiving said sealing structure of said plunger; a first container, said first container is retained within said barrel, said first container retaining a substance, said first container is configured to be punctured by said first piercing element when a user depresses said plunger within said barrel of said syringe; wherein said first container includes at least one longitudinal channel located on an outer wall surface of said first container to allow for the substance to move along the outer surface from a proximal end to a distal end of the first container; and, a second container, said barrel of said syringe retaining at least a portion of said second container, said second container retaining a substance, said second container is configured to be punctured by said first piercing element when a user depresses said plunger within said barrel of said syringe. ### Claim 14 (depends on 13) The syringe of claim 13, wherein said first container is collapsible. ### Claim 15 (depends on 13) The syringe of claim 13, wherein said plunger having at least one recess retaining an alcohol pad. ### Claim 16 (depends on 15) The syringe of claim 15, wherein said at least one recess of said plunger having a removable lid. ### Claim 17 (depends on 13) The syringe of claim 13, wherein said second container having a flange, said flange is connected to an end of said second container. ### Claim 18 (depends on 13) The syringe of claim 13, wherein said second container having a first diameter and a second diameter, said second diameter is greater in size than said first diameter.
