AI Technical Summary

Technical Problem

Existing IV catheter systems face challenges in achieving fast and reliable flashback visibility, especially in primed systems lacking vented flash chambers, due to diffusion of blood with saline and slow transfixation observation.

Method used

An introducer needle with a first and second notch, along with a transparent catheter and a flash chamber, facilitates pressure-driven blood flow through dual fluid pathways, enhancing flashback visibility and detection of transfixation, even after priming.

Benefits of technology

The solution provides rapid and visible flashback, improving first needle stick success by ensuring clear detection of catheter placement in the vasculature, even in primed systems.
