Abstract

A portable emergency medical monitoring and transmission system capable of sending a message to a personal caretaker and/or an emergency response center. The system includes a wearable monitor/transmitter device including a glucose level detector, a geolocation system, and a communication interface to send and/or receive a message. A processor operable within the device collects information produced by the glucose level detector and the geolocation system to determine whereabouts and existence of a hypoglycemic or hyperglycemic condition of the patient. Upon detecting an unsafe medication condition, the processor assembles a message that includes patient identifier data, whereabouts of said patient, and an emergency alert indication; and activates a transmitter to transmit an emergency message in response to a hypoglycemic or hyperglycemic condition. An optional caretaker receiver receives the message and produces a local alarm indicating that the patient requires assistance. A transmission path of the transmitter conveys, in response to an emergency alert indication, the emergency message to an emergency response center indicating that the patient needs help.
