Definitions
- the present invention relates to a method for transmitting and receiving biometric information between a sensor transmitter and a communication terminal in a continuous blood glucose measurement system. It determines whether unreceived biometric information exists only in a non-received communication period that is relatively larger than the regular communication period, and if there is unreceived biometric information, the computational load and non-receipt
- the present invention relates to a method for transmitting and receiving biometric information capable of reducing energy waste required to receive biometric information every regular communication period.
- Diabetes mellitus is a chronic disease that occurs frequently in modern people, with more than 2 million people in Korea accounting for 5% of the total population.
- Diabetes mellitus is caused by an absolute or relatively insufficient amount of insulin produced by the pancreas due to various causes such as obesity, stress, wrong eating habits, and congenital heredity. get sick and get sick
- Blood usually contains a certain concentration of glucose, and the tissue cells get energy from it.
- glucose increases more than necessary, it is not stored properly in the liver, muscle, or fat cells and is accumulated in the blood. As it is excreted, sugar, which is absolutely necessary for each tissue in the body, becomes insufficient, causing abnormalities in each tissue of the body.
- Diabetes mellitus is characterized by almost no subjective symptoms in the early stages. As the disease progresses, the symptoms characteristic of diabetes include polyphagia, polyuria, weight loss, general malaise, itchy skin, and long-lasting wounds on the hands and feet that do not heal. As the disease progresses further, complications that progress to visual impairment, hypertension, kidney disease, stroke, periodontal disease, muscle spasms and neuralgia, and gangrene appear.
- Diabetes mellitus needs to constantly measure blood sugar for management, so the demand for devices related to blood sugar measurement is steadily increasing. It has been confirmed through various studies that, when diabetic patients strictly control blood sugar, the incidence of complications of diabetes is significantly reduced. Accordingly, it is very important for diabetic patients to measure blood sugar regularly to control blood sugar.
- a finger prick method is mainly used for blood sugar management in diabetic patients.
- Such a blood prick method helps the diabetic patient to manage blood sugar, but because only the result at the time of measurement is displayed, the blood sugar level that changes frequently is monitored. There is a problem that is difficult to pinpoint precisely.
- the blood-collecting type blood glucose device needs to collect blood every time to measure blood glucose frequently during the day, so there is a problem in that the burden of blood collection is large for diabetic patients.
- Diabetics typically alternate between hyperglycemic and hypoglycemic states, with emergencies occurring in hypoglycemic states. Hypoglycemia occurs when the sugar does not last for a long time and can lead to loss of consciousness or, in the worst case, death. Therefore, prompt detection of hypoglycemic conditions is very important for diabetic patients. However, there is a clear limit to the blood sampling type blood glucose meter that measures blood glucose intermittently.
- CGMS continuous glucose monitoring system
- the continuous blood glucose measurement system includes a sensor transmitter attached to a body part of a user to measure blood glucose by extracting body fluid, and a communication terminal for outputting a received blood glucose level.
- the sensor transmitter measures the user's blood sugar for a predetermined period, for example, about 15 days, while the sensor is inserted into the human body to generate blood sugar information.
- the sensor transmitter periodically generates blood sugar information, and the communication terminal periodically receives the blood sugar information and outputs the received blood sugar information so that the user can check it.
- the sensor transmitter and the communication terminal transmit and receive blood glucose information through a wired communication method or a wireless communication method, and the communication terminal must continuously receive transmission packets from the sensor transmitter without loss.
- the communication terminal cannot continuously receive blood glucose information from the sensor transmitter, and this prevents the user from continuously monitoring his or her blood glucose information through the communication terminal. happens to be
