Urodynamix Technologies, a Canadian medical device company, has partnered with wireless network provider
Motion Computing to offer a bladder-monitoring system that leverages
radio frequency identification to improve the product's safety.
Urodynamix's UroNIRS 2000 Bladder Monitor System is a standalone device that employs near-infrared spectroscopy (NIRS)—a spectroscopic method utilizing the near-infrared region of the electromagnetic spectrum (wavelengths that are 800 to 2,500 nanometers)—to measure changes in blood flow in a patient's bladder and abdominal walls. Near-infrared emissions consist of the spectrum just beyond red light, and are invisible to humans. The system is designed to help physicians diagnose and treat enlarged prostates, prostatic cancer and other health problems related to the bladder and prostate gland.

The UroNIRS 2000 Bladder Monitor System includes a
base station, built by Urodynamix, and Motion Computing's Motion C5 mobile clinical assistant (MCA), a handheld tablet PC that comes with a built-in Bluetooth
transceiver and a 13.56 MHz
RFID interrogator compliant with the
ISO 15693 standard. The C5 fits into the base station, which analyzes data collected from an adhesive patch with fiber-optic cables that connect to the station.
Designed to be affixed to a patient's skin during testing, the patch contains a light emitter that projects near-infrared light, and a sensor that can receives near-infrared waves reflected back by the patient's internal organs. The patch collects the waves reflecting from that person's organs and sends them, via the fiber-optic cable, to the base station, where they are processed and converted to digital data. The C5 then displays the test results in real time, so physicians can discuss the findings with patients in the examination room. The C5 can utilize its integrated Bluetooth technology to download data from the base station, thereby eliminating the need for the device to be docked in the base station in order to access and display the test results.
The C5's RFID
reader is used to capture the unique ID numbers from passive RFID tags embedded in the packaging of the single-use patches. Doctors can easily scan a patch prior to each test to enhance patient safety by ensuring each patch is used only on a single patient, thus eliminating the spread of infection that might result from attaching the same patch to multiple individuals.
