Abstract
A blood collection device to prime a blood flow path may include a cannula, a holder, and an elastomeric sleeve. The cannula may include a proximal end, a distal end, and a lumen extending along a longitudinal axis therebetween. The cannula may include a slot to enable a user to visualize the blood flow path through the cannula. The holder may include a channel configured to align with the longitudinal axis to retain a shaft of the cannula. The holder may further include a visual check window corresponding to the slot of the cannula. The elastomeric sleeve may be coupled to the holder and enclose the proximal end of the cannula. A priming opening may be disposed between the elastomeric sleeve and the holder to prime the blood flow path.

A blood collection device to prime a blood flow path, comprising:
- a cannula comprising a proximal end, a distal end, and a lumen extending along a longitudinal axis therebetween, the cannula comprising a slot to enable a user to visualize a blood flow path through the cannula;
- a holder comprising a proximal end, a distal end, and a channel extending therebetween, the channel configured to align with the longitudinal axis to retain a shaft of the cannula, the holder comprising a visual check window corresponding to the slot of the cannula;
- and
- an elastomeric sleeve coupled to the holder and enclosing the proximal end of the cannula, wherein a priming opening is disposed between the elastomeric sleeve and the holder to prime the blood flow path.
A blood collection system, comprising:
- an adapter comprising a distal port, a first proximal port, and a second proximal port;
- a blood collection device coupled to the first proximal port, the blood collection device comprising:
- a body comprising a distal end, a proximal end, and longitudinal axis extending therebetween;
- a septum disposed within the body;
- a cannula comprising a distal end and a sharp proximal end, wherein the cannula extends through the septum;
- an elastomeric sleeve coupled to the body and covering the sharp proximal end of the cannula;
- an air pipe extending through the septum;
- and
- an air membrane disposed proximal to the air pipe;
- wherein an air priming pathway comprises the air pipe and the air membrane, and wherein a blood collection pathway separate from the air priming pathway comprises the cannula.
