The Symphony blood glucose meter uses the method of continuous monitoring of glucose by collecting subcutaneous tissue fluid by skin dialysis. The basic principle is to use an electric grinding head to treat the surface of the skin and remove the cuticle to a level close to the dermis to form a round about the size of a dime. An electrochemical sensor device is used to continuously suck out the subcutaneous tissue fluid and measure the glucose concentration therein. The resulting data is transmitted wirelessly to a computer, display or smartphone. The product can continuously collect dynamic blood glucose data. <br />Each sensor probe has a service life of about 24 hours and is mainly used for inpatients.
