The traditional family sphygmomanometer is like a mute who can only "count" mechanically. It can only give blood pressure values, but it cannot provide effective guidance according to the current blood pressure situation and the patient's symptoms. Children, due to a lack of medical knowledge, living away from their parents, busy work and many other factors, find it difficult to always pay attention to and take care of their parents' blood pressure conditions, and fall into the difficult situation of "powerless care".

For elderly parents, they are often at a loss in the face of "high pressure warning". For example, when the blood pressure reaches 195/110mmHg, they do not know whether to take the medicine immediately or lie down for observation; they cannot remember the contraindication combination of nitroglycerin and antihypertensive drugs; and they do not understand the critical point of "temporary relief" and "must be sent to the hospital". Every minute of delay is like installing a time bomb on the blood vessel, which increases the risk of the blood vessel bursting dramatically.
