  • Patent number: 12268481
    Abstract: A blood pressure monitoring device includes a wrist strap, a case, and a display. The strap portion is adapted to fasten the device to the wrist without occluding blood flow. At least one sensor modality is arranged within the case for obtaining sensor data from an artery in the wrist. In a preferred embodiment photoplethysmography sensors are incorporated in the case to generate PPG waveform data. A processor within the case is operable to compute mean arterial pressure, and optionally diastolic and systolic blood pressure based on extracted and computed features of the sensor data. Related methods and systems are also described.
