Abstract
A device for transferring fluids includes a piercing member having a distal end and a proximal end and defines a longitudinal fluid channel. An opening is positioned at the distal end of the piercing member with the opening in fluid communication with the longitudinal fluid channel. Further, a sleeve having a proximal end and a distal end includes an extended position where the sleeve surrounds the piercing member and a retracted position where the sleeve is retracted from the distal end of the piercing member. The sleeve defines an opening at the distal end of the sleeve with a gap defined between the retractable sleeve and the piercing member.
Claims19
A device for transferring fluids comprising:
- a piercing member having a distal end and a proximal end and defining a longitudinal fluid channel, an opening is positioned at the distal end of the piercing member, the opening in fluid communication with the longitudinal fluid channel;
- and
- a sleeve having a proximal end and a distal end, the sleeve having an extended position where the sleeve surrounds the piercing member and a retracted position where the sleeve is retracted from the distal end of the piercing member, the sleeve defining an opening at the distal end of the sleeve, wherein a gap is defined between the retractable sleeve and the piercing member,
- wherein an interference fit is established between the piercing member and the sleeve,
- wherein the proximal end of the piercing member is sealed with an innermost surface of a proximal end of the sleeve via the interference fit, and
- wherein the gap between the piercing member and the sleeve extends continuously from the seal between the proximal end of the piercing member and the proximal end of the sleeve to a distalmost end of the sleeve.
