Problems solved by technology

[0002] Existing sphygmomanometers are mainly dual-side blood pressure, which cannot fully reflect the blood pressure of the person being tested. However, ambulatory sphygmomanometers measure blood pressure multiple times at regular intervals, which leads to poor user experience and cannot be accepted by the market.

Embodiment Construction

[0024] The invention provides a continuous blood pressure measurement device based on a photoelectric volume sensor, which is applied in the technical field of blood pressure measurement. The continuous blood pressure measurement device based on a photoelectric volume sensor of the present invention uses two photoelectric volume sensors to measure blood pressure, which can continuously monitor blood pressure without an inflatable belt The uncomfortable feeling from the patient improves the wearing comfort very well. At the same time, the self-calibration of the blood pressure data is carried out by using the arm-type oscillometric blood pressure monitor, which effectively improves the accuracy of the blood pressure data, and the acceleration sensor cooperates with the collection of user body position information and judgment The blood pressure measurement state corrects data to improve the accuracy of the calculated blood pressure value.

[0025] In order to make the object, te...

Abstract

The invention discloses a continuous blood pressure measurement device based on a photoelectric volume sensor, which includes an information detection layer, an information processing layer, and an information feedback layer. The information detection layer includes a first photoelectric volume sensor, a second photoelectric volume sensor, a blood pressure processing module, an oscilloscope Method blood pressure acquisition module, acceleration sensor, information processing layer includes: power supply, A/D sampling module, embedded processing module, memory, serial port, oscillometric method blood pressure acquisition module comprises arm type oscillometric method blood pressure monitor, the present invention adopts two The photoelectric volume sensor measures blood pressure, which can continuously monitor blood pressure without the discomfort caused by inflation, which greatly improves the wearing comfort. Accuracy, and the acceleration sensor cooperates to collect the user's body position information, and judge the blood pressure measurement state correction data, and improve the accuracy of the calculated blood pressure value.

Description

technical field [0001] The invention relates to the technical field of blood pressure measurement, in particular to a continuous blood pressure measurement device based on a photoelectric volume sensor. Background technique [0002] Existing sphygmomanometers are mainly dual-side blood pressure, which cannot fully reflect the blood pressure of the test subject. However, ambulatory sphygmomanometers measure blood pressure multiple times at regular intervals because of the need for pressurized measurements, resulting in poor user experience and cannot be accepted by the market. [0003] Existing continuous sphygmomanometers can solve the problem of occasional blood pressure measurement by measuring pulse wave velocity to continuously monitor human blood pressure. It will bring an uncomfortable experience. Second, the data model of the calculated blood pressure cannot be corrected by itself, resulting in comfort and accuracy that cannot meet the user's requirements, and cannot ...
