Abstract
The application includes an improved syringe (100) for use with a receptacle of the type having a self-contained movable piercing member. 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.

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. - View Dependent Claims (11, 12, 13, 14, 15, 16)

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. - View Dependent Claims (18, 19, 20)

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. - View Dependent Claims (22, 23, 24, 25)
