The government should increase the burden of medical expenses on the people and, as a basic policy, shift from the conventional direction of "early detection and early treatment of illness" to the direction of "building health to prevent illness". I'm watching.

[0003] As one of the means for effectively performing this "building health to prevent illness", a "home health management system" has been proposed. This system measures data related to a health condition that can be measured in a general household (for example, a blood pressure value measured by an electronic sphygmomanometer, a body temperature measured by a thermometer, and the like) in each home, and stores the data in a dedicated terminal. The device transmits the data to a medical institution or an insurance center via a communication network such as a public line or a CATV line so that the data can be analyzed and diagnosed by a specialist. According to such a home health care system, daily health care at home can be performed under the guidance of a specialist, and more reliable health care can be performed, and the number of hospital visits can be reduced. Will lead to
