Transferset for vials and other medical containers
First Claim
1. A polymeric fluid transfer member for transferring fluids from a first container having a radial rim portion surrounding an open end and a second container, comprising:
- an integral outer tubular member including a tubular collar portion having an open free end adapted to receive said rim portion of said first container and a proximal end, a generally radial portion integral with said proximate end of said tubular collar portion, and a tubular enclosure portion having a diameter less than said tubular collar portion having a proximate end integrally joined, to said generally radial portion and an open distal end; and
an inner tubular member having a diameter less than said tubular enclosure portion located within and generally coaxially aligned with said tubular enclosure portion in spaced relation having an open proximal end and an open distal end;
wherein said generally radial portion includes an annular barb extending generally perpendicular to said generally radial portion adapted to sealingly engage a polymeric stopper received in said open end of said first container.

Abstract
An improved transferset assembly for transferring fluids between a first container, such as a medicament vial and a second container, such as a syringe, which includes an integral polymeric transfer assembly having a tubular collar portion, a radial portion overlying the rim of the first container, an outer tubular portion and an inner tubular portion which is integrally joined to the outer tubular portion by a radial intermediate web portion, a piercing member telescopically received in the inner tubular portion having a piercing end to pierce the closure sealing the open end of the first container and a removable closure which seals the open ends of the outer and inner tubular portions of the transfer assembly. The tubular collar portion, which may be separate from the inner and outer tubular portions, is formed of composite polymer including a relatively soft polymer and a relatively rigid polymer, such that the free end of the collar portion may be deformed radially inwardly or crimped into the neck of the first container, yet sufficiently rigid to retain its shape following deformation and resistant to creep to maintain a seal between the transfer assembly and the first container. The proximate end of the inner tubular portion includes a sharp edge which seals against the closure of the first container. The preferred embodiment of the closure is frangibly connected to the free end of the outer tubular portion of the transfer assembly and provides a biological seal.
