Abstract

A transfer set for transferring fluids from a first container, such as a conventional vial, to a second container, such as a conventional syringe. The transfer set includes an integral tubular housing having a tubular collar surrounding the rim of the vial, a radial portion sealingly engaging the stopper in the vial, an integral tubular transfer member and an outer tubular portion surrounding at least the distal portion of the tubular transfer member, a piercing member within the tubular transfer member and a closure releasably retaining the distal end of the piercing member.

Claims

1. A transfer set for transferring fluids between a first container including an open end, a rim portion surrounding said open end and a pierceable closure in said open end sealing said first container, and a second container, said transfer set comprising:

an integral body including a first tubular portion surrounding said rim portion of said first container have an open end secured to said rim portion of said first container, a radial portion integral with said first tubular portion overlying rim portion of said first container, a second tubular portion integral with said radial portion having an open proximal end overlying said pierceable closure generally coaxially aligned with said open end of said first container and a distal open adapted to receive said second container, and a third tubular portion integrally joined to said second tubular portion having a distal open end surrounding said distal open end of said second tubular portion in spaced relation;

a piercing element telescopically received in said second tubular portion having a piercing end adjacent said pierceable closure and moveable within said second tubular portion to pierce said pierceable closure and establish fluid communication between said first and second containers through said second tubular portion; and

a removable closure overlying and sealing said distal open end portion of said third tubular portion.

2. The transfer set as defined in claim 1, wherein said third tubular portion is joined to said second tubular portion by a generally radial bridging portion integrally joined to a midportion of said second tubular portion.

3. The transfer set as defined in claim 2, wherein said distal open end portion of said third tubular portion is generally concentric with and spaced from said distal open end of said second tubular portion.

4. The transfer set as defined in claim 1, wherein said distal open end of said second tubular portion includes a Luer connection adapted to threadably receive a Luer connection of said second container.

5. The transfer set as defined in claim 1, wherein said radial portion of said integral body overlies said pierceable closure and said radial portion including a plurality of generally concentric ribs surrounding said second tubular portion sealingly engaging said pierceable closure.

6. The transfer set as defined in claim 5, wherein said concentric ribs are circular and coaxially aligned with said second tubular portion.

7. The transfer set as defined in claim 5, wherein said concentric ribs have a sharp circular edge biting into said pierceable closure.

8. The transfer set as defined in claim 5, wherein said radial portion includes radial ribs adjacent said first tubular portion engaging said pierceable closure and preventing rotation of said transfer set relative to said first container.

9. The transfer set as defined in claim 1, wherein said open end of said first tubular portion is permanently deformed radially beneath said rim portion of said first container, permanently attaching said transfer set to said first container.

10. The transfer set as defined in claim 1, wherein said piercing element includes an elongated body portion releasably contained in said second tubular portion of said body by said closure.

11. The transfer set as defined in claim 10, wherein said second tubular portion includes an internal abutment surface and said body portion of said piercing element includes a radial portion preventing withdrawal of said piercing element from said second tubular portion.

12. The transfer set as defined in claim 1, wherein said open proximal end of said second tubular portion includes an axially extending barb surrounding said open proximal end sealingly engaging said pierceable closure and providing sealed communication between said first container and said second tubular portion.

13. The transfer set as defined in claim 1, wherein said second tubular portion of said body is generally cylindrical and said third tubular portion is bell-shaped having a rim portion surrounding said distal open end of said second tubular portion and a proximal end portion extending generally radially inwardly and integrally joined to a midportion of said second tubular portion.

15. The transfer set as defined in claim 14, wherein said proximal end portion of said third tubular portion is joined to said second tubular portion by a radial bridging portion integrally joined to a midportion of said second tubular portion.

16. The transfer set as defined in claim 15, wherein said third tubular portion is bell-shaped having a rim portion surrounding said distal open end of said second tubular portion in spaced relation and a generally radially inwardly extending portion integrally joined to said midportion of said second tubular portion.

17. The transfer set as defined in claim 14, wherein said distal open end of said second tubular portion includes a Luer connector adapted to threadably receive a threaded end portion of said second container.

18. The transfer set as defined in claim 14, wherein said plurality of generally concentric ribs are circular and coaxially aligned with said second tubular portion.

19. The transfer set as defined in claim 14, wherein said plurality of generally concentric ribs each have a sharp circular edge biting into said pierceable closure.

20. The transfer set as defined in claim 14, wherein said radial portion includes radial ribs adjacent said first tubular portion sealingly engaging said pierceable closure.

21. The transfer set as defined in claim 14, wherein said open distal end of said first tubular portion is permanently deformed radially beneath said rim portion of said first container permanently attaching said transfer set to said first container.

22. The transfer set is defined in claim 14, wherein said piercing element includes an elongated body portion having a distal end releasably retained in said second tubular portion by said removable closure.

23. The transfer set as defined in claim 14, wherein said open proximal end of said second tubular portion includes an axially extending barb sealingly engaging said pierceable closure and providing sealed communication between said first container and said second tubular portion.

14. A transfer set for transferring fluids between a first container including an open end, a rim portion surrounding said open end and a pierceable closure in said open end sealing said first container and a second container, said transfer set comprising:

an integral body including a first generally cylindrical tubular portion surrounding said rim portion of said first container having an open distal end secured to said rim portion of said first container and a proximal end portion, a radial portion integral with a proximal end of said first tubular portion extending radially inwardly and overlying said pierceable closure, a second generally cylindrical tubular portion integral with a radial inner extent of said radial portion extending generally perpendicular to said radial portion having an open proximal end overlying said pierceable closure generally coaxially aligned with said open end of said first container and a distal open end adapted to receive said second container, said radial portion including a plurality of generally concentric ribs surrounding said open proximal end of said second tubular portion sealingly engaging said pierceable closure, and a third tubular portion having an open distal end surrounding said distal open end of said second tubular portion and a proximal end portion integrally joined to said second tubular portion spaced from said radial portion;

a piercing element telescopically received in said second tubular portion having a piercing end opposite said pierceable closure and moveable within said second tubular portion to pierce said pierceable closure and establish fluid communication between said first and second containers through said second tubular portion; and

a removable closure overlying and sealing said distal open end portion of said third tubular portion.
