Posted on September 19, 2009
DexCom
DexCom™, Inc., headquartered in San Diego, California, is a company focused on pioneering technologies for the continuous monitoring of glucose in people with diabetes. DexCom has developed a short term continuous glucose monitoring system, the Seven™ System, which includes the Seven Sensor, the Seven Transmitter, and the Seven Receiver.
The tiny probe-like Sensor is inserted by the user under the skin, and is held in place by an adhesive. Once inserted, the Sensor begins continuously monitoring glucose. The Transmitter sends the glucose signal from the Sensor and wirelessly transmits the data to the hand-held Receiver. The Receiver processes the glucose signal and with the push of a button, displays the user’s current glucose value, as well as 1-hr, 3-hr, and 9-hr trends. The Receiver also sounds an alert when a high or low glucose excursion is detected.
