Abstract: An injection syringe (100) comprises a barrel having a distal end and a proximal end; and finger member(s) non-slidably attached to a distal portion of the barrel. The finger member is 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. Independent claims are also included for: (1) a medical reconstitution system (200) for a composition (50) comprising mixable first and second constituents (30, 40), comprising a receptacle (20) containing the first constituent; and a syringe containing the second constituent; (2) delivering a multi-constituent composition for injection, comprising providing a first constituent in a receptacle having a pierceable seal, a piercing member (25) movable between a retracted position and a fully-pierced position, and a first connector (27) in fluid communication with the piercing member; providing a second constituent in an injection syringe having finger member(s) proximate to a distal end of the syringe, and having a second connector on the distal end of the syringe; connecting the first and second connectors while the piercing member is in the retracted position; displacing the piercing member from the retracted position to the fully-pierced position by pushing the distal finger member (150) toward the receptacle, thus causing the piercing member to pierce the seal; injecting the second constituent from the syringe into the receptacle through the first and second connectors and the piercing member; causing the first and second constituents to mix together in the receptacle to form the composition; and drawing the composition into the syringe from the receptacle through the piercing member and through the first and second connectors; and (3) a distal finger brace for a hypodermic syringe having a barrel with a proximal end and a distal end, comprising a central bore sized and configured to receive a portion of the syringe barrel proximate to the distal end of the barrel; a lip configured to positively engage the distal end of the barrel; and outwardly extending finger tab(s). The receptacle comprises a container including a pierceable seal; a piercing member configured to selectively pierce the pierceable seal, and being operable between a retracted position and a fully pierced position; a first connector connected to and in fluid communication with the piercing member; and a sterile shield (28) surrounding the seal and the piercing member. The syringe comprises a barrel having a distal end, a proximal end, and a second connector on the distal end, where the second connector is configured to engage the first connector of the receptacle and provide a fluid-tight connection with the first connector; and the finger member(s). 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.
