Abstract:
1. A resealable transfer set for transferring fluid between a first container having an opening sealed with a pierceable closure and a second container, said transfer set comprising: a generally tubular elastomeric fluid transfer valve member mounted on said first container having an open end portion generally coaxially aligned with said opening of said first container and a generally closed portion spaced from said open end portion having a longitudinal slit therethrough, said longitudinal slit being biased to a closed position, and a piercing member telescopically received within said fluid transfer valve member between said open end portion and said generally closed portion generally coaxially aligned with said first container opening, said piercing member having a first relatively sharp piercing end portion opposite said pierceable closure and a second distal end portion opposite said generally closed portion of said transfer valve member, whereby a generally tubular portion of said second container may be driven through said slit in said generally closed portion of said fluid transfer valve member against said second distal end portion of said piercing member, driving said first piercing end portion of said piercing member through said pierceable closure and establishing fluid communication between said first and second containers, wherein said generally tubular elastomeric fluid transfer valve member includes an outwardly tapered tubular portion adjacent said generally closed portion and said piercing member second distal end portion is enlarged to be closely received in said outwardly tapered tubular portion of said fluid transfer valve member releasably retaining said piercing member in said fluid transfer valve member, wherein said transfer set includes a generally tubular luer connector member surrounding said fluid transfer valve member having a lateral opening adjacent said outwardly tapered tubular portion of said elastomeric fluid transfer valve member, permitting said outwardly tapered tubular portion to expand laterally and release said distal end portion of said piercing member.
