## 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.

## Claims

### Claim 1

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; and
at least one opening positioned at the distal end of the piercing member, the at least one opening in fluid communication with the longitudinal fluid channel, wherein the piercing member includes at least one flat portion,
wherein the piercing member includes first and second flat portions provided on different planes, and
wherein the first and second flat portions each extend along a side surface of the piercing member.

### Claim 2 (depends on 1)

The device according to claim 1, wherein the piercing member defines a longitudinal vent channel, and wherein the piercing member includes first and second flat portions positioned circumferentially between the longitudinal vent channel and the longitudinal fluid channel, the first flat portion positioned opposite the second flat portion.

### Claim 3 (depends on 2)

The device according to claim 2, wherein the first and second flat portions are configured to reduce a penetration force required to pierce a sealing member of a fluid container relative to a piercing member not having the first and second flat portions.
