Automated IV Device - SAGIV (BioDesign) (Hadasit)

Summary

Need:
Insertion of intravenous (IV) catheter is a common clinical procedure carried out 190 million times per year in the United States alone.
While the procedure is common, it is associated with high failure rates:
30% failure in Adults
44% failure in Children

Common causes for failure:
Misidentification of the vein
Late feedback of needle penetration
Vein piercing due to anatomy and manual challengeInnovation:
Our solution addresses the 3 procedure needs:
1. Vein identification:
The SAGIV uses line of sight near infrared (NIR) imaging to provide caregivers with enhanced visualization of sub-cutaneous veins.
Contrast is created due to 100-fold higher absorption of hemoglobin in blood compared to peripheral tissue which is composed primarily of water.

2. Needle insertion identification:
The SAGIV uses catheter imbedded electrodes to sense changes in alternating current resistance (impedance) to monitor vein insertion in real time (milliseconds).

3. Robotic Cannula Insertion:
The SAGIV uses simple robotics to insert the needle into the target vein, deposit the catheter and simultaneously withdraw the needle safely into a plastic cartridge.
We design the SAGIV for 2 degrees of freedom, forward - backward axis and upward rotation.
