RS TechMedic uses Sierra Wireless modules to transmit patient data in real time

21 Jan 2011

RS TechMedic BV, a medical technology provider based in The Netherlands, is using the Sierra Wireless AirPrime Q2687 EDGE wireless module in its Dyna-Vision telemedicine device for cardiopulmonary applications.

The Dyna-Vision is a multi-purpose remote patient monitoring device for cardiologists, general practitioners and health centres. About the size of a PDA and carried by the patient on a belt, the unit is connected to non-invasive sensors attached to the skin which measure up to twelve clinical parameters, including heart rate, respiratory rate, temperature, plethysmogram (changes in volume within an organ), SpO2 (the patient’s oxygen saturation level) and skin temperature.

The latest feature of Dyna-Vision is to accurately predict critical medical conditions of patients, such as cardiac arrest, up to six hours before they occur. By early intervention by medical staff, it is now possible to prevent the patient's condition from deteriorating. This feature helps healthcare providers reduce complications, patient injuries and length of hospital stays.

Using the highly integrated Sierra Wireless AirPrime Q2687 wireless module, the Dyna-Vision device transmits data in real time to a doctor’s office via a cellular network, enabling extensive remote diagnostics in cardiology, pulmonology and neurology.

“The AirPrime Q2687 provides the perfect connectivity solution for the Dyna-Vision,” said Rutger Brest van Kempen, CEO of RS TechMedic. “An advanced integrated TCP/IP stack, small module size and low current consumption were essential criteria for us, since our product is carried around by the patient and is running on an internal battery.

"The fact that the module is fully certified for European and US markets made the certification of the Dyna-Vision itself fast and easy for us. Last but not least, the professional integration support we received from our Sierra Wireless distributor, Alcom Netherlands, was of great help in creating a robust and efficient telemedicine solution which responds to patients’ and practitioners’ needs.”

The Dyna-Vision transmits measurements automatically with no intervention from the patient, and patients can be monitored for long periods of time without having to come back to the practice. Patients experiencing symptoms or other events can use the unit to alert the physician, who can simply log in to the server to monitor the actual streaming parameters and take action as required. The Dyna-Vision unit is part of a turn-key offer, which includes a server solution and PC software in addition to the monitoring device.

Didier Dutronc, Senior Vice President and General Manager, M2M Embedded Solutions for Sierra Wireless, added: “Wireless healthcare or telemedicine is one of the most exciting applications of machine-to-machine communication technology today, and we are very pleased to be working with some of the pioneers in this space. The Dyna-Vision device is a wonderful example of how wireless technology can help improve people’s lives.”
