Transfer set
First Claim
1. A transfer set for transferring fluid from a first container having an open end sealed with a pierceable closure and a second container, said transfer set comprising:
- a tubular housing member having a proximate end adapted to be attached to said first container open end and an open distal end;
a cap releasably attached to said open distal end of said tubular housing member sealing said open distal end, wherein said cap includes a central tubular portion extending toward and receiving said distal end of said piercing member, releasably retaining said piercing member; and
a piercing member telescopically supported in said tubular housing member by said cap having a proximate piercing end adapted to pierce said closure of said first container and a distal end releasably attached to said cap, said cap releasably retaining said piercing member during assembly of said transfer set on said first container and prior to removal of said cap, wherein said piercing member distal end has an enlarged free end including a camming surface having a diameter greater than an internal diameter of said central tubular portion of said cap which is received in said central tubular portion terminating in a relatively sharp edge which bites into an internal surface of said central tubular portion of said cap, releasably retaining said piercing member to said cap.

Abstract
A transfer set for transferring fluid from a first container, such as a conventional sealed vial, to. a second container, such as a conventional syringe having a luer connector without a needle canula. The transfer set includes a tubular housing member having a proximate end adapted to be attached to the first container open end, a tubular transfer member located within the tubular housing member, a piercing member telescopically supported in the tubular transfer member, and a cap or closure which in the preferred embodiments releasably retains the distal end of the piercing member prior to removal of the cap. The cap includes a central portion having a tubular connector portion which receives and releasably retains the distal end of the piercing member.

13. A transfer set for transferring fluid from a first container having an open end sealed with a pierceable closure and a second container, said transfer set comprising:
-
a tubular housing member having a proximate end adapted to be attached to said first container open end and an open distal end;
a generally tubular transfer member located within said tubular housing member having a proximate end adapted to sealingly engage said closure in said open end of said first container;
a cap having a central portion overlying and sealing said open distal end of said tubular housing member, wherein said cap central portion includes an integral connector releasably retaining said piercing member distal end, wherein said integral connector is a central tubular portion extending toward and receiving said distal end of said piercing member releasably retaining said piercing member; and
a piercing member telescopically received in said tubular transfer member having a proximate piercing end adapted to pierce said closure and a distal end releasably attached to said cap central portion, whereby said cap releasably retains said piercing member during assembly of said transfer set on said first container prior to removal of said cap, wherein said piercing member distal end includes an enlarged free end having a camming surface having a diameter greater than an internal diameter of said central tubular portion of said cap which is received in said central tubular portion terminating in a relatively sharp edge which bites into an internal surface of said central tubular portion of said cap, releasably retaining said distal end of said piercing member in said central tubular portion. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A transfer set for transferring fluid from a first container having an open end, a rim portion surrounding said open end, a reduced diameter neck portion adjacent said rim portion, a pierceable closure received in said open end sealing said first container and a second container, said transfer set comprising:
-
a generally tubular housing member including a tubular collar portion adapted to surround said rim portion of said first container having a free end adapted to be secured to said neck portion of said first container, an integral radial portion adapted to overlay said rim portion of said first container and a tubular housing portion integral with said radial portion generally coaxially aligned with said first container open end having an open distal end;
a generally tubular transfer member located within said tubular housing portion of said tubular housing member having a proximate end sealingly engaging said closure in said first container open end and an open distal end;
a piercing member telescopically received in said tubular transfer member having a proximate piercing end adapted to pierce said closure and an open distal end; and
a cap having a central portion releasably secured to and sealing said open distal end of said tubular housing portion of said tubular housing member having an integral connector portion releasably retaining said distal end of said piercing member prior to removal of said central portion of said cap from said tubular housing member. - View Dependent Claims (25, 26, 27, 28, 29)
