Robotic IV insertion device means less pain for kids

Administering fluids to patients is carried out through intravenous (IV) catheters, inserting a needle in a vein in a common medical procedure. However, the motor coordination required to insert an IV catheter is very demanding, particularly in children and infants. This often causes pain, distress and frustration.

To address this need, Hebrew University of Jerusalem students and Hadassah Medical Center clinicians, attending the joint Biodesign program, created a semi-automatic handheld device for rapid and safe IV insertion. Called SAGIV, the device uses infrared sights and electrical sensing to identify veins, insert the needle into the correct location, and withdraw it in a single, rapid robotic movement.

"Inserting an IV is a demanding procedure, and many times children need to be pricked 5, 6 or more than 10 times for successful insertion," said Dr. Yotam Almagor, the group's clinical expert. "This leads to a lot of pain and frustration." The group's prototype, developed by engineering graduate student Lev Lavy, has already been tested successfully on children at the pediatric ward of Hadassah Medical Center. "We had a lot of excited parents asking that we use the device," said Almagor. "Children that used to be pricked numerous times in every visit can now be connected in a single attempt."

Other students in the group include Gahl Levy, founder of EnergySmart Solutions, as well as Yifat Castel and Alex Wainshtok, who are completing their MBA degrees.

Biodesign is a multi-disciplinary, team-based approach to medical innovation, created by the Hebrew University of Jerusalem and Hadassah Medical Center in partnership with Stanford University. The program takes outstanding medical fellows, bioengineering and business graduate students, and tutors them in the science and practice of bringing a medical innovation to the market. The program is directed by Dr. Yaakov Nahmias, head of the Bioengineering program at the Hebrew University, and Prof. Chaim Lotan, director of the Heart Institute at Hadassah Medical Center.

Other teachers include, Prof. Dan Galai, Dr. Niron Hashai, and Dr. David Planer.
