BLOOD PRESSURE MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/103805
Kind Code:
A1
Abstract:
A blood pressure measurement device, comprising a main body (1), a wristband (3), an air bag (2), an air supply and exhaust apparatus (9), a first sensor (4) and a second sensor (5), wherein the air bag (2) has an air cavity, and the air bag (2) is connected to the main body (1); the main body (1) comprises a cavity, and the air supply and exhaust apparatus (9) is arranged in the cavity; the air supply and exhaust apparatus (9) comprises an air inlet path and an air leakage path, so that the air supply and exhaust apparatus (9) is in communication with the air cavity of the air bag (2); the first sensor (4) is used for measuring an air pressure value in the air cavity; the wristband (3) is connected to the main body (1), and the second sensor (5) is arranged on the wristband (3); and the second sensor (5) is located on the same side of the wristband (3) as the air bag (2) and is used for measuring a pulse wave signal. A blood pressure value is obtained according to the air pressure value, which is measured by the first sensor (4), and the pulse wave signal, which is measured by the second sensor (5).
