  • Electronic sphygmomanometer measuring method, system, electronic sphygmomanometer, and storage medium
    Patent number: 11771331
    Abstract: An electronic sphygmomanometer measuring method, comprising: acquiring a barometric pressure sequence (S110); obtaining a systolic pressure/diastolic pressure on the basis of the barometric pressure sequence (S120); extracting characteristic information of the barometric pressure sequence (S130); and correcting the systolic pressure/diastolic pressure on the basis of the characteristic information (S140). The measuring method increases the precision in calculating the systolic pressure/diastolic pressure. Also disclosed accordingly are an electronic sphygmomanometric system, an electronic sphygmomanometer, and a storage medium.

  • Respiratory monitoring apparatus, method and device
    Patent number: 10881331
    Abstract: A respiratory monitoring apparatus comprises at least one motion sensor and a processing device. The at least one motion sensor senses an angular motion of a measured part capable of indicating a respiratory motion, and outputs an angular velocity vector of the measured part; the processing device, connected to the motion sensor, extracts a respiratory angular velocity from the angular velocity vector, and acquires a respiratory wave according to the respiratory angular velocity.
