AI Technical Summary

Technical Problem

Existing blood collection devices face issues with air priming procedures that can lead to contamination, inaccurate diagnosis due to sample dilution, and clotting, as well as the inability to visualize blood flashback without a collection tube attached, which can affect sample volume and clog fluid pathways.

Method used

The blood collection device incorporates a cannula with a slot for visualization, an elastomer sleeve for automatic sealing, and separate air and blood pathways to ensure proper air priming and blood collection, using a holder and adapter system that automatically seals and separates air and blood paths, preventing contamination and ensuring accurate sample collection.

Benefits of technology

The device effectively prevents contamination, ensures accurate blood collection by visualizing flashback, and maintains sample integrity by separating air and blood pathways, thereby reducing the risk of clotting and dilution.

Abstract

A blood collection device for priming 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 that allows a user to visualize the blood flow path through the cannula. The holder may include a channel configured to align with the longitudinal axis for holding the shaft of the cannula. The holder may further include a visual check window corresponding to the slot in the cannula. An elastomeric sleeve may be coupled to the holder and surround the proximal end of the cannula. A priming opening may be disposed between the elastomeric sleeve and the holder for priming the blood flow path.
