BD&E to Prototype Dehydration Optosensor

Optical instrumentation maker Bodkin Design and Engineering (BD&E) LLC is partnering with Boston Children’s Hospital to develop an optical sensor that measures dehydration in infants.

Bodkin is working with Dr. Vassilios Bezzerides, who invented an electronic device to measure such dehydration. Funding was provided by CIMIT (Center for Integration of Medicine & Innovative Technology), a nonprofit consortium of Boston teaching hospitals and universities, to develop a beta prototype for clinical trials.

Capillary refill time is a common measure of blood flow and is conducted by pinching and releasing a patient’s fingertip and observing the time it takes for the blood to refill. The longer the refill time, the more dehydrated the patient.

The prototype instrument BD&E is designing uses an optical sensor and computer to objectively measure this effect, and can be used not only in infants, but also athletes, the elderly or the incapacitated.
