Oscillometric watch-type sphygmomanometer

Mainstream electronic sphygmomanometers, oscillometric watch sphygmomanometers have been registered by CFDA and MedicalCE

Tension method watch type sphygmomanometer

Tension method, also called arterial tension method, is a new blood pressure measurement method with mature theory. In the 1960s, Pressman et al. pioneered a non-invasive continuous blood pressure measurement method based on arterial tonometry.

Photoelectric-ECG blood pressure tracking watch
The theory is mature, and the photoelectric-electrocardiogram (PPG-ECG) blood pressure tracking watch has passed the CFDA registration.

Photoelectric-electrocardiography (PPG-ECG) blood pressure measurement is a method of measuring blood pressure using auscultation or oscillometric methods. Based on the measured blood pressure value, the photoelectric-electrocardiography (PPG-ECG) sensor is used to measure the pulse wave. The method of PWV or PWTT to estimate continuous blood pressure.

The photoelectric-electrocardiogram (PPG-ECG) blood pressure tracking watch is part of this continuous blood pressure measurement method, and requires regular (no more than 24 hours) calibration (or calibration) to measure blood pressure using auscultation or oscillometric methods.
