  • Patent number: 11612329
    Abstract: A method for adjusting an output signal of a pulse diagnosis device includes obtaining a pulse signal at a pulse diagnosis region that is acquired by a sensing element of the pulse diagnosis device, and performing a parameter recognition on the pulse signal to obtain a parameter of the pulse signal, and determining a biological structure of the pulse diagnosis region based on the parameter of the pulse signal. The method also includes determining an adjustment factor for the parameter of the pulse signal based on the biological structure, and adjusting the parameter of the pulse signal based on the adjustment factor for the parameter of the pulse signal, to obtain an adjusted pulse signal for the pulse diagnosis region. The pulse signal is a pressure signal applied by an artery in the pulse diagnosis region to an external skin surface corresponding to the artery.

  • Publication number: 20220296104
    Abstract: Disclosed are a pulse meter and a control method therefor, aiming at solving the problem that a plurality of sensors in the existing pulse meter cannot fit well with the wrist surface. The pulse meter comprises a main body, a compression mechanism disposed on the main body, a plurality of pressure sensors (12) connected with the compression mechanism, and a controller (6) in communication connection with the compression mechanism and the pressure sensors (12). The compression mechanism comprises a compression airbag (21) and an air pump assembly connected with the compression airbag (21); the compression airbag (21), when inflated, can enable the plurality of presser sensors (12) to abut the wrist surface at approximately the same preset pressure.
