Since then, Terumo's electronic sphygmomanometers for home use have undergone many improvements and continue to play a vital role in the maintenance of public health.
One of the indicators of human health is blood pressure. If left untreated, high blood pressure causes arteriosclerosis (hardening of the arteries), heart diseases, and cerebral hemorrhage. Terumo decided to develop an electronic blood pressure monitor for the home-use, that are trusted by doctors due to their high accuracy, and are also easy to use. The development concept was drawn up and the technical associates went to work. In October 1988, Terumo launched an electronic blood pressure monitor that worked at the touch of a button, did not apply excessive cuff pressure, and was highly reliable.
