SYSTEMS AND METHODS FOR WIRELESS PROCESSING AND TRANSMITTAL OF DATA FROM A PLURALITY OF MEDICAL DEVICES
One method according to the present invention includes receiving data wirelessly from a plurality of medical devices, transmitting the data to an intermediary device (such as a properly equipped mobile telephone or personal digital assistant), and formatting a message including the received data for transmission to a medical data server. This method can be practiced automatically to allow a medical device for a patient or other subject to be monitored without requiring the patient to manually enter information. This method also allows for multiple different medical devices to be monitored, even where such devices each communicate on different frequencies and/or using different communication protocols.
