Title:
WRISTWATCH STRAP
Document Type and Number:
WIPO Patent Application WO/2019/071878
Kind Code:
A1
Abstract:
A wristwatch strap, comprising a physiological signal acquisition module, a wireless communication module (304), and a microprocessor (MCU) (303), the physiological signal acquisition module comprising an air bag (3021) and a sensor assembly (3022). When the wristwatch strap is wrapped around the wrist, the wireless communication module (304) connects to a terminal, wherein the wireless communication module (304) is configured to receive a blood pressure measurement instruction sent by the terminal. The MCU (303) is configured to respond to the blood pressure measurement instruction by instructing the air bag (3021) and the sensor assembly (3022) to measure a physiological signal by oscillometry, determining a first blood pressure reading according to the physiological signal, and sending the first blood pressure reading to the terminal by means of the wireless communication module (304). The present solution enables a user to conveniently and accurately acquire blood pressure data during everyday life, and the air bag is relatively aesthetically pleasing. The use of a non-invasive blood pressure measurement technique can improve the user experience without compromising data accuracy or wearing aesthetics. Moreover, the apparatus can be medically certified on its own without the need to medically certify the entire wearable device.
