Israeli medical device start-up NightSense has developed an application to alert sleeping diabetics if their blood sugar suddenly falls at night, a medical emergency called hypoglycemia, Israeli business daily Globes reported on Tuesday.

The company estimates that each day there are 200,000 severe hypoglycemic attacks, when insulin flushes sugar from the body faster than the patient can produce it, with 5 per cent of juvenile diabetes sufferers dying from it.

NightSense was developed by three Israelis — Gadi Kan-Tor, Yoav Kan-Tor and Shy Hefetz — who specialize in creating medical devices.  Kan-Tor, whose research and development experience is from the Israel Defense Force’s Satellite Unit, is a diabetic and served as a guinea pig for their product trials.

The product resembles a watch. It analyzes subtle changes in the movement of the patient’s hand that indicate changes in pulse and heart activity.

“There are ten motions that are recognized by doctors as being affected by hypoglycemia. Not every patient will exhibit the same symptoms, nor will they exhibit them with the same intensity. Therefore, we customize the product for each individual patient, according to his or her ‘classic’ gestures when lying still,” Kan-Tor told Globes.

“We spoke to doctors and they told us that they prescribe lower insulin doses than the patient really needs, due to their fear of its negative effects during the night,” Kan-Tor said.

However, high daily blood-sugar levels causes damage to kidneys, eyes, and the extremities.

“The doctors said, ‘if you solve the night problem, we will be able to give the correct dosage,'” he said.

The company received $200,000 from the Tnufa fund, along with an additional investment from the founders and is currently seeking further funding. It plans to begin clinical trials in 2014.

  • Can you tell me if this device is yet available in the US. My brittle type one 47 year old daughter husband has left her and she is alone at night and I fear hpyo incidents.

    Since so many of the BDStard are old sickly q-tips they will love boycotting this.

    Hopefully people like this can also discover the “Cure” for Alzheimer’s, now “public enemy #1” enabled by the Medical Advances made over the last 2 decades, allowing more people to achieve Advanced Age, where Alzheimer’s thrives.

    Well this is sad for me as my wife was a diabetic living in Israel during the 80s and the care was so bad she died at 35. Along the way either myself or previously her friends had to call Magen David Adom 25 times to revive her from a coma. Somehow I feel that her sad story inspired this product.

    Could you please send me information on the cost of this device, and where it can be purchased? Does it work during the day for people suffering from hypoglycemia?

  • Your work sounds exciting and promising. It could benefit your company as well as the State of Israel, domestically and internationally. We might be able to assist with your search for additional funding.
