Problems solved by technology
[0003] At present, the devices for measuring PWV are large-scale equipment, which are measured by means of ECG and cuffs (Muron's arteriosclerosis detector). Therefore, it is necessary to develop a miniaturized, low-cost, and easy-to-use PWV measurement device for the popularization of PWV measurement technology in health management.

The invention discloses a novel weighing scale and method for measuring the blood flow velocity, the novel weighing scale comprises a weighing scale base and a supporting panel, a weighing pressure sensor is arranged below the supporting panel, the weighing pressure sensor is electrically connected with a main control panel, an ECG electric contact electrode plate and a piezoelectric thin film sensor are arranged in the containing cavity of the weighing scale base, the main control board receives the ECG detected by the ECG contact electrode plate and the pulse wave detected by the piezoelectric thin film sensor, and calculates the time difference between the ECG pacing time point and the pulse pacing time point; the main control board is further connected with a data input module, and themain control board calculates the blood flow speed according to the input human body height or the pulse length from the heart chamber to the foot sole. The novel weighing scale not only has a traditional weighing function, but also can quickly measure the blood flow speed of a human body, so that the miniaturization of the PWV measuring equipment is realized, and the portability is high, the cost is low, and the daily measurement requirements of people can be met.
Description
technical field [0001] The invention relates to the technical field of weight measurement, in particular to a novel weight scale and a method for measuring blood flow velocity. Background technique [0002] Pulse wave velocity (PWV) refers to the rate at which a pulse wave propagates from a specific location along the artery wall to another specific location. Pulse wave velocity is a non-invasive index used to reflect the elasticity and expandability of arteries. The higher the PWV value, the harder the vessel wall, and it can be used to evaluate the degree of arteriosclerosis. [0003] At present, the devices for measuring PWV are large-scale equipment, which are measured by means of ECG and cuffs (Muron's arteriosclerosis detector). Therefore, it is necessary to develop a miniaturized, low-cost, and easy-to-use PWV measurement device to popularize PWV measurement technology in health management. Contents of the invention [0004] For this reason, the technical problem ...
