Blood pressure monitoring device and method

Abstract

The invention relates to a blood pressure monitoring device and method. The device comprises a contact part, a sending module and amicroprocessor, wherein the sensing module is embedded in the contact part and used for monitoring vibration caused by the fact that the heart of the detected person is propagated to the periphery along the artery blood vessel and the blood flow and converting the vibration into an electric signal, and the sensing module comprises two flexible films and an optical fiber sensor fixedly arranged in the two flexible films; and the microprocessor is connected with the sensing module and is used for extracting the pulse conduction time from the electric signal, establishing a blood pressure estimation model and monitoring the blood pressure in real time according to the blood pressure estimation model. The optical fiber sensor embedded in the contact part is used for detecting the vibration of the human body caused by the fact that the heart is transmitted to the periphery along the artery blood vessel and the blood flow, and the device has high sensitivity and is resistant to electromagnetic interference. A user only needs to wear the contact part of the monitoring device on a related part of a human body or make contact with the related part of the human body to achieve real-time and continuous blood pressure monitoring, and the blood pressure monitoring device has the advantages of being compact in structure, small in size, convenient to carry, easy and convenient to operate and the like.

Description

technical field [0001] The present invention relates to the technical field of blood pressure monitoring, and more specifically, to a blood pressure monitoring device and method. Background technique [0002] Blood pressure (blood pressure, BP) refers to the lateral pressure that blood acts on the vessel wall per unit area when blood flows in the blood vessel. normal metabolism. Blood pressure is also an important part of diagnosing diseases, observing changes in conditions and judging treatment effects. If the blood pressure is too high or too low, it will have serious consequences on the human body, such as damage to blood vessels and organs, insufficient blood supply of cerebral arteries, etc. Therefore, effective blood pressure monitoring will feed back the blood pressure value to the user, so that they can understand their own blood pressure, thereby preventing the occurrence of diseases. [0003] Most of the traditional blood pressure monitoring devices are arm-type...

AI Technical Summary

Problems solved by technology

Such a monitoring method will cause the blood vessels in the arm to deform to a certain extent due to the pressure of the cuff, which will easily lead to low accuracy of re-measurement in a short period of time. Only the blood pressure value at a certain moment can be obtained, and continuous blood pressure monitoring cannot be performed.

At the same time, the pressure generated by the cuff on the user's wrist will cause discomfort to the user, and the volume is large and the portability is poor.
