Blood Collection Devices, Systems, and Methods to Facilitate Air Priming

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.
