The syringe includes a barrel (114) having a distal end (114d) and a proximal end (114p). At least one finger member (150) is provided proximate to the distal end (114d) of the barrel (114). The finger member (150) is non-slidably attached to the barrel (114) and configured to permit application of a substantial force by one or more fingers of a person's hand such that the syringe (100) is urged in a distal direction. ## Claims ### Claim 1 An injection syringe comprising: (a) a barrel having a distal end and a proximal end; and (b) at least one finger member non-slidably attached to a distal portion of the barrel, the finger member being configured to permit application of a substantial force by one or more fingers of a person's hand such that the syringe is urged in a distal direction. ### Claim 2 (depends on 1) A syringe according to claim 1 wherein the finger member comprises: (a) a first finger tab on a first side of the barrel; and (b) a second finger tab on a second side of the barrel. ### Claim 3 (depends on 2) A syringe according to claim 2 wherein the first and second sides of the barrel are substantially opposite each other. ### Claim 4 (depends on 1) A syringe according to claim 1 wherein the barrel comprises glass. ### Claim 5 (depends on 1) A syringe according to claim 1 wherein the finger member comprises a polymeric material. ### Claim 6 (depends on 1) A syringe according to claim 1, further comprising a first connector on the distal end of the barrel, the first connector being configured to matingly engage a second connector on a medical device. ### Claim 7 (depends on 6) A syringe according to claim 6 wherein the first connector is configured to matingly engage a second connector on a composition receptacle. ### Claim 8 (depends on 1) A syringe according to claim 1, further comprising a pharmaceutical composition within the barrel. ### Claim 9 (depends on 1) A syringe according to claim 1, wherein the finger member is removably attached to the distal portion of the barrel. ### Claim 10 A medical reconstitution system for a composition comprising first and second mixable constituents, the system comprising: (a) a receptacle containing the first constituent, the receptacle comprising: (i) a container including a piercable seal; (ii) a piercing member configured to selectively pierce the piercable seal, the piercing member being operable between a retracted position and a fully-pierced position; (iii) a first connector connected to and in fluid communication with the piercing member; and (iv) a sterile shield substantially surrounding the seal and piercing member and (b) a syringe containing the second constituent, the syringe comprising: (i) a barrel having a distal end, a proximal end, and a second connector on the distal end, the second connector being configured to engage the first connector of the receptacle and provide a substantially fluid-tight connection therewith; (ii) at least one finger member non-slidably attached to a distal portion of the barrel, the finger member being configured to permit application of a force by one or more fingers of a person's hand such that the syringe is urged in a distal direction; (c) wherein when the piercing member is in the retracted position and the first and second connectors are sealingly engaged together, the piercing member is capable of being advanced to the fully-pierced position by pushing and displacing the finger member in the distal direction toward the receptacle. ### Claim 11 (depends on 10) A system according to claim 10 wherein the first constituent comprises an antihemophilic factor and the second constituent comprises a diluent therefor. ### Claim 12 (depends on 10) A system according to claim 10, further comprising an injection needle configured to sealingly connect to the second connector of the syringe. ### Claim 13 (depends on 10) A system according to claim 10 wherein at least a portion of the finger member of the syringe contacts a portion of the sterile shield when the piercing member is advanced to the fully pierced position. ### Claim 14 (depends on 10) A system according to claim 10 wherein the barrel of the syringe comprises glass. ### Claim 15 (depends on 10) A system according to claim 10 wherein the syringe further comprises a plunger disposed in the barrel. ### Claim 16 (depends on 10) A system according to claim 10 wherein the first and second connectors are compatible luer-lock connectors. ### Claim 17 A method of delivering a multi-constituent composition for injection, the method comprising: (a) providing a first constituent in a receptacle having a piercable seal, a piercing member movable between a retracted position and a fully-pierced position, and a first connector in fluid communication with the piercing member; (b) providing a second constituent in an injection syringe having at least one finger member proximate to a distal end of the syringe, and having a second connector on the distal end of the syringe; (c) connecting the first and second connectors while the piercing member is in the retracted position; (d) displacing the piercing member from the retracted position to the fully-pierced position by pushing the distal finger member toward the receptacle, thereby causing the piercing member to pierce the seal; (e) injecting the second constituent from the syringe into the receptacle through the first and second connectors and piercing member; (f) causing the first and second constituents to mix together in the receptacle to form the composition; and (g) drawing the composition into the syringe from the receptacle through the piercing member and through the first and second connectors. ### Claim 18 (depends on 17) The method according to claim 17 wherein at least a portion of the finger member of the syringe meets a portion of the receptacle when the piercing member is in the fully-pierced position to provide a visual indication to a user that the syringe is fully engaged with the receptacle. ### Claim 19 (depends on 17) The method according to claim 17 wherein the syringe and receptacle are substantially transparent such as to substantially permit viewing of the first and second constituents and mixtures thereof within the receptacle and syringe. ### Claim 20 (depends on 17) The method according to claim 17 wherein the first constituent is an antihemophilic factor and the second constituent is a compatible diluent therefor. ### Claim 21 A distal finger brace for a hypodermic syringe having a barrel with a proximal end and a distal end, the distal finger brace comprising: (a) a central bore sized and configured to receive at least a portion of the syringe barrel proximate to the distal end of the barrel; (b) a lip configured to positively engage the distal end of the barrel; and (b) at least one outwardly extending finger tab. ### Claim 22 (depends on 21) A distal finger brace according to claim 21, further comprising a U-shaped recess that permits the brace to be engaged onto the syringe barrel from a side of the barrel. ### Claim 23 (depends on 21) A distal finger brace according to claim 21, further comprising at least one upwardly extending wall that at least partially surrounds the central bore. ### Claim 24 (depends on 21) A distal finger brace according to claim 21, further comprising at least one downwardly extending stop. ### Claim 25 (depends on 21) A distal finger brace according to claim 21, further comprising a resilient polymeric material.
