Healthcare Informatics Online has a grab bag of new mobile tech in their July issue. Some of these items are just cool devices that could be integrated into an overall solution, like the HP Digital Pen 200. The Symbol 8800 is rather old news, but the writer Frank Jossi,
highlights the health care requirements of "dropability" (the ability
to withstand dripping wipes of disinfectant is another requirement).

Of note is the RF Technologies new Seeker Mobile Locating Solution.
RF Technologies has usual patient and asset tracking apps you'd expect.
The Seeker system is made up of RFID asset tags and a PDA-based mobile
reader. With the mobile reader, you can wander around, and like James
Bond, be guided to a specific asset. The mobile reader, "can poll up to
57,600 programmable RFID asset tags at ranges up to 300
feet. Audible “beeps” and flashing lights on the RFID tags indicate
precisely which tagged assets have been successfully located. The
handheld reader also provides a gauge on how far the tag is located
from the current position of the Seeker by means of the signal strength
indicator." This would be useful in areas where RFID receivers have not
been deployed for automated tracking. No info on their site as to the
technology used in their system.

Also of note is the MedicTouch Pulse Meter
wireless pulse oximeter sensor system. Details are pretty sketchy, but
it seems that you connect a "best in class" SpO2 sensor (Nellcor and
Masimo?) to a smart phone that supports J2ME (provided by Medic Touch).
The phone runs software (no additional hardware is mentioned) that
processes data from the sensor and displays a heart rate that can be
archived or sent (via the cell phone's network) to a Java compliant
server. The system was designed to support an array of sensors in the
future.

And seemingly, no mobile tech roundup is complete without a mention of Vocera.
