Fully automatic system for monitoring blood pressure from a toilet-seat using the volume-oscillometric method.

Daily monitoring of health condition at home is very important subject not only as an effective scheme for early diagnosis and treatment of cardiovascular and other diseases, but also for prevention and control of such diseases. From this point of view, we have been developing a fully automated "non-conscious" monitoring system for home health care. In this paper are described, structural detail of a newly developed toilet-seat-installed blood pressure measurement system and some results obtained by the system. Also described is outline of a newly designed system for measuring hydrostatic pressure difference between the heart and the measuring site, i.e., thigh, during blood pressure measurement.
