Cardiovascular health monitoring device and cardiovascular health monitoring method

Abstract

The invention relates to a cardiovascular health monitoring device and a cardiovascular health monitoring method. The cardiovascular health monitoring device comprises a shell, a control circuit, an inflatable pressure pulse sphygmomanometer, a pump, at least one first electrode, a second electrode and an ear wearing structure, wherein the inflatable pressure pulse sphygmomanometer surrounds an upper limb of a user; the pump is accommodated in the shell; and the first electrodes are arranged on the ear wearing structure. When blood pressure is measured, a processor controls the pump to inflate or deflate the pressure pulse sphygmomanometer, so that the blood pressure of the user can be detected. When an electrocardiosignal is measured, the ear wearing structure is worn on an ear of the user, the first electrodes are in contact with the skin of the ear or the skin close to the ear, the pressure pulse sphygmomanometer surrounds the upper limb, the second electrode is in contact with the skin of the upper limb, and the processor can acquire the electrocardiosignal via the first electrodes and the second electrode.

Description

technical field [0001] The invention relates to a cardiovascular health monitoring device and method, in particular to a cardiovascular health monitoring device with blood pressure and electrocardiographic signal measurement functions, and a method for monitoring cardiovascular health through the device. Background technique [0002] Modern people pay more and more attention to their own health, especially cardiovascular health, and sphygmomanometer is one of the most commonly used home monitoring devices for monitoring cardiovascular health in daily life, not only because of its convenience, but also because of Hypertension is one of the risk factors associated with various chronic diseases such as heart disease and diabetes. [0003] One of the most common sphygmomanometers at home is the electronic sphygmomanometer. The operation process is to fix the cuff first, then press the start button and wait for the blood pressure measurement to be completed automatically. Such a ...

Problems solved by technology

[0014] However, the biggest problem faced by this method is also caused by using hands to operate.

When using the hands-on form, such as figure 2 As shown, the problem that will be faced is the low stability of the operation, because the way of measuring with both hands is easy to cause unstable phenomena such as hand shaking during measurement, resulting in baseline drift and waveform deformation of the measured ECG. ,like Figure 4A Therefore, compared with the normal ECG signal waveform, it will lead to incorrect analysis results; in addition, when the user wants to keep the hand stable and the muscles are tense, or deliberately exert force to ensure the distance between the electrode and the electrode When in contact, it is also easy to generate myoelectric signals due to force, such as Figure 4B As shown, it will also cause signal quality degradation, which will lead to incorrect ECG analysis results

[0015] When holding the device with one hand and touching the chest with the other side, if image 3 As shown, compared with two-handed operation, it can be more stable, and the signal obtained is also stronger. However, this operation method has the biggest disadvantage, that is, the measurement must be carried out only when the clothes are lifted to touch the chest, which will make the user feel apprehensive. In addition, the fluctuation of the chest cavity due to breathing will also cause relative movement between the electrodes touching the chest and the electrodes touching the hand, which will also easily cause baseline drift and affect the measured ECG
