Abstract
A fluid transfer adapter for use with a syringe barrel having an open proximal end including a collar having adapter engaging structure and a distally-facing frusto-conically shaped surface comprises a hub having a proximally-facing frusto-conically shaped surface for mating with the frusto-conically shaped surface on the barrel, structure for threadably engaging the hub to the collar of the barrel so that the frusto-conically shaped surface of the hub contacts the frusto-conically shaped surface of the barrel to prevent liquid flow between the surfaces and a fluid transfer having a passageway therethrough, connected to the distal end of the hub so that the lumen is in fluid communication with a conduit in the hub.

A fluid transfer adapter for use with a syringe barrel having an inside surface defining a chamber, an open proximal end and an open distal end including a collar having adapter engaging structure and a distally facing frusto-conically shaped surface comprising:
- a hub having a proximal end, a distal end and a conduit therethrough, and a proximally-facing frusto-conically shaped surface for mating with said frusto-conically shaped surface of said barrel;
- means for threadably engaging said hub to said collar so that said frusto-conically shaped surface of said hub contacts said frusto-conical surface of said barrel;
- and
- a fluid transfer element including a cannula having a distal end, a proximal end, and a lumen therethrough, said proximal end of said cannula being connected to said distal end of said hub so that said lumen is in fluid communication with said conduit.
A fluid transfer adapter for use with a syringe barrel having an inside surface defining a chamber, an open proximal end and an open distal end including a collar having adapter engaging structure and a distally facing frusto-conically shaped surface comprising:
- a hub having a proximal end, a distal end and a conduit therethrough, and a proximally-facing frusto-conically shaped surface for mating with said frusto-conically shaped surface of said barrel;
- means for threadably engaging said hub to said collar so that said frusto-conically shaped surface of said hub contacts said frusto-conical surface of said barrel;
- and
- a fluid transfer element including an elongate luer tip having a distal end, a proximal end, and a passageway therethrough, said proximal end of said luer tip being connected to said distal end of said hub so that said passageway is in fluid communication with said conduit.
A fluid transfer apparatus comprising:
- a syringe barrel having an inside surface defining a chamber, an open proximal end and an open distal end including a collar having adapter engaging structure and a distally facing frusto-conically shaped surface;
- and
- a fluid transfer adapter including a hub threadably engaged with said collar, said hub having a proximal end, a distal end, a conduit therethrough, and a proximally-facing frusto-conically shaped surface mating with said frusto-conically shaped surface on said barrel, and a fluid transfer element having a distal end, a proximal end, and a passageway therethrough, said proximal end of said fluid transfer element being connected to said distal end of said hub so that said passageway is in fluid communication with said conduit.
