Abstract
A device for transferring fluids in a closed system transfer device using flash for last drop extraction and to reduce coring. The device including a piercing member having a distal end and a proximal end and defining a longitudinal fluid channel. A first opening positioned at the distal end of the piercing member wherein the first opening is in fluid communication with the longitudinal fluid channel. A cover or flash positioned over the first opening. The cover including a pre-cut pattern wherein the cover opens along the pre-cut pattern upon application of a distally directed force from the longitudinal fluid channel. The distal end including the first opening having a steep taper to facilitate last drop extraction.
Claims19
A device for transferring fluids comprising:
- a piercing member having a distal end and a proximal end and defining a longitudinal fluid channel, a first opening positioned at the distal end of the piercing member, the opening in fluid communication with the longitudinal fluid channel;
- and
- a cover positioned over the first opening, the cover including at least one hinge connecting the cover to the piercing member, and a pre-cut pattern, wherein the cover opens along the pre-cut pattern upon application of a distally directed force from the longitudinal fluid channel.
A device for transferring fluids comprising:
- a body having a first side and a second side;
- a piercing member extending from the second side of the body, the piercing member having a distal end and a proximal end and defining a longitudinal fluid channel;
- at least a first opening positioned at the distal end of the piercing member, the at least one first opening in fluid communication with the longitudinal fluid channel;
- and
- a cover positioned over the first opening, the cover including at least one hinge connecting the cover to the piercing member, and a pre-cut pattern wherein the cover opens along the pre-cut pattern upon application of a distally directed force from the longitudinal fluid channel.
