U.K. mobile device vendor Cellnovo has developed a way to connect a diabetes pump to a mobile monitoring system to send real-time data in the cloud to physicians.

has developed a system to transfer data from a wirelessly connected insulin
pump to a cloud-based cellular system in real time.
pump, attached to the body with Velcro, connects wirelessly to a touch-screen
that resembles an Apple iPhone but doesn't make
calls. Cellnovo has disabled the voice capabilities of the mobile monitor as a
safety feature. This allows an uninterrupted flow of insulin from the pump to
the patient, William F. McKeon, CEO of Cellnovo, told eWEEK.

McKeon. The handset packetizes the data and transmits it to a secure back-end
over a GSM radio.

said McKeon. "All of that information is constantly being communicated to
the handset, and once that information is on the handset, that information gets
moved up over the mobile network."
By wearing the

conducting trials with 100 type 1 diabetes patients in 10 leading diabetes
centers in the United Kingdom to determine how connecting a wireless insulin
pump to a wireless data-transfer system will help them regulate their diet and take
the proper amount of insulin. The usability trial allows patients to share data
and caregivers to evaluate it remotely in real time.

Cellnovo system provides us immediate access to the clinical status of all our
patients on a single screen," trialist Stephen Greene, a professor at the
University of Dundee, said in a statement.
diabetes management system is part of a remote-monitoring trend in health care,
according to McKeon. Mobile technology will become embedded in medical devices
on a regular basis, he predicted.
McKeon believes that eventually the device will matter less and the real value
is with the cloud-based platform. In a way, it mirrors how the iPod became less
important as Apple's iTunes moved toward a more cloud-based model.
the real seismic shift, moving from MP3 players to iTunes," said McKeon.
"The device has become less important. What's most important is in the
cloud, and it's the same way with managing a patient."

20 to 25 percent of patients in a large part of Europe and North America use
pump technology, according to Cellnovo. The company aims for its cellular
touch-screen system to ease adoption of insulin pump therapy and simplify care
of diabetes patients.

The vendor must demonstrate to the FDA that the product is safe to get
real-time data provided to doctors, McKeon hopes that more diabetes patients
will be able to avoid losing limbs and eyesight. By using software to record blood sugar and diet numbers and by connecting to cellular radios to transmit the data, people could possibly live
longer and healthier "without the burden of this disease," he said.
