The other day I spoke with Ofer Atzmon of Tadiran, the maker of
MDKeeper and got a bit more background and news on their efforts. My
earlier post on MDKeeper is here. First a little background on Tadiran Spectralink.
Founded in 1976, Tadiran Spectralink targets advanced wireless
communications systems mostly in defense and security markets where
high reliability are required. Tadiran has about 160 employees, 75% of
which are engineers, programmers and techs. One of their core
competencies, the design of high bit rate data links for commercial
applications based on cellular, satellite and Point-to-Point data
communications systems, lead to development of MDKeeper.

The company is in the process of opening an office in the US and working out a distribution strategy.

Participation in some European funded telemedicine R&D projects and
talks with home health care providers gave rise to MDKeeper. They've
started their 510k application and are in talks with some big name
teaching hospitals about clinical trials in the US. They expect to be
market-ready in the first half of 2006.

Ofer sees two key advantages MDKeeper has over current products. The
first is that MDKeeper can work anywhere; because the radio used to
transmit data is a GPRS cellular radio there is no dependency on a home
phone connection. There's also a feature that provides push-button
voice communications between the patient and their provider. Operation
is automatic; there are no wireless sensors fiddle with because
everything is built in. Ambulatory blood pressure monitoring and
congestive heart failure (CHF) are the initial target markets for the
device. Parameters supported include one lead ECG, SpO2, and heart
rate. They're looking at technology now to measure BP at the wrist.
Data can be read and transmitted periodically (timed or patient
initiated) or continuous. The intended use does not include life
threatening continuous monitoring, but the device will generate alarms.
The complete solution also includes a server and web client for
acquiring and managing patient data.

MDKeeper was designed in a modular fashion in anticipation of
supporting additional or different physiological parameters and
different radios. The effort required to support WiFi for hospital use
is not significant. The device also has a serial interface to connect
to other devices (i.e., wireless sensors). Other interfaces are in the

All in all, a pretty cool device.
