It is especially important to measure blood glucose levels. As you get older, insulin secretion decreases, but even if it is secreted, insulin does not work well, so the frequency of diabetes increases with age.

As people grow older, the progression of arteriosclerosis throughout the body accelerates, and some people have a number of related diseases such as hypertension and dyslipidemia (hyperlipidemia). In addition, there are many diabetic complications such as retinopathy and neuropathy.

Diabetes is originally a disease in which subjective symptoms are difficult to occur, but in the case of elderly people, the physical functions are deteriorated, so that the subjective symptoms are further reduced. In addition, even if there is an abnormality, it may be overlooked due to age, so the complications of diabetes may be considerably advanced due to the progress of arteriosclerosis.

Therefore, it is important to constantly measure the blood glucose level of a subject such as the elderly.

In addition, since the position of the first terminal is known, if there is something in the person to be watched over, such as the elderly, an ambulance can be immediately dispatched to that place.

Specifically, the "current position" and "current time" are always transmitted from the satellite, and the first position signal unit 210 (GPS satellite receiver) of the first terminal 200 receives the radio signal from the satellite. Then, the first position signal unit 210 multiplies the time taken for the signal to arrive by the speed of the radio wave to determine the distance between the satellite and the first position signal unit 210.

This is repeated with multiple satellites above the area of subject A. Then, the current position of the first terminal 200 is specified from the calculated distances to the plurality of satellites.

Notifies the second terminal 500 via. When the emergency notification unit 412 is used, the third terminal 600 is also notified.

The abnormality determination unit 400 determines whether or not the body temperature of the subject A is abnormal based on the information sensed by the acceleration sensor S3.

For example, when the subject A is exercising, the body temperature becomes higher than usual. Therefore, when the abnormality determination unit 400 determines that the subject A is exercising by the acceleration sensor S3, the subject A is taken into consideration.

The blood glucose level determination unit 350 calculates and determines the blood glucose level of the subject A based on the information sensed by the blood glucose level sensor S5.

As we get older, our sensory functions such as eyesight and hearing, motor functions including muscular strength, and heart and respiratory functions decline. And the secretion of insulin from the pancreas also decreases with age.

In addition, as people get older, it becomes difficult to obtain the effect of insulin that lowers blood sugar due to a decrease in muscle mass, an increase in visceral fat, and a decrease in activity, and as a result, the proportion of people with diabetes increases.

In addition, elderly people with diabetes tend to have higher postprandial blood glucose. Even in the case of hypoglycemia, hypoglycemic symptoms such as sweating, palpitation, and tremor of the hands are less likely to appear, and severe hypoglycemia may occur without taking measures such as taking sugar.

Hypoglycemia in the elderly can increase the burden of continuing diabetes treatment and reduce quality of life. In addition, severe hypoglycemia leads to falls / fractures, dementia, and cardiovascular disease.

With aging, the drug becomes more likely to accumulate in the body, so the effect becomes stronger than before, leading to hypoglycemia, and the risk of side effects increases.

In addition, the frequency of cerebral infarction, ischemic heart disease, and peripheral arterial disease of the lower extremities increases. Therefore, it is preferable for the elderly to constantly measure the blood glucose level.
