A new wearable monitoring medical device to make treatments easier and more affordable for the millions of people with swallowing disorders is about to be released into the market.

Dr Georgia A. Malandraki, an Associate Professor of Speech, Language, and Hearing Sciences in Purdue University’s College of Health and Human Sciences, and Dr Chi Hwan Lee, an Assistant Professor of Biomedical Engineering and Mechanical Engineering in Purdue’s College of Engineering, founded Curasis LLC and serve as an acting chief executive officer and chief technology officer, respectively. They started the company to commercialize their wearable technology and move it as quickly as possible to clinics and people with swallowing difficulties.

Dr Malandraki told Thailand Medical News, “We want to provide a reliable, patient-friendly and affordable way to treat the millions of people with swallowing disorders. Many medical devices to help these people are expensive, not able to be taken home and not accessible in many rural areas.”

The biotech researchers created a skin-mountable sensor sticker that attaches firmly to the neck area and is connected with small cables to a wireless transmitter unit.

The developed skin-mountable sensor sticker measures and records muscle activity and movement associated with swallowing. The information is then sent wirelessly by a separate unit clipped on the wearer’s shirt to software that stores it for later analysis by a doctor.

Typically, the successful completion of a swallow requires the precise coordination of more than 30 pairs of muscles of the head and neck, six pairs of cranial nerves, and complex circuitry in the brainstem and several brain areas. Any disruption in these pathways can result in severe swallowing disorders.

About 6 million adults and more than 450,000 children experience severe swallowing disorders each year in the U.S.
Dr Lee added, “Our medical device is unique in that we specifically created it to work well with the small and intricate muscles associated with swallowing events. The sensor sticker is stretchable and flexible to work well with the skin and curvilinear head and neck shape, while the connected unit has electronic chips and more rigid components.”

The accompanying sensor stickers are disposable, designed with inexpensive components and meant to be used about 10 times before they are thrown away.
