Cardiovascular monitoring device

Abstract

The invention relates to a cardiovascular monitoring device which can measure blood pressure and an electrocardio signal at the same time. The cardiovascular monitoring device comprises an inflatable band used for surrounding limbs of a user, at least one first electrode and one second electrode, a control circuit contained in a shell and a display device used for displaying information of blood pressure measurement and / or electrocardio signal measurement, wherein the control circuit can execute the blood pressure measurement by controlling pressure in the band and can execute the electrocardio signal measurement by virtue of the electrodes; and meanwhile, special design on positions and types of the electrodes as well as a contact type between the electrodes and the skin of the user is provided by the invention to realize stable contact between the electrodes and the skin of the user.

Description

technical field [0001] The present invention relates to a cardiovascular monitoring device, more particularly, to a cardiovascular monitoring device capable of simultaneously providing blood pressure measurement and electrocardiographic signal measurement functions. Background technique [0002] Blood pressure and electrocardiogram (ECG) are common physiological signals used to monitor cardiovascular health in daily life. [0003] In order to increase the possibility of measuring these two physiological signals at home, blood pressure measuring devices and ECG monitoring devices for home use have been developed, mainly because the operating procedures of these two physiological signals are quite simple, convenient, and Non-invasive, and therefore, more and more users will have these two devices at home. [0004] In hospitals, it is also quite common to use both blood pressure and ECG to assess a patient's cardiovascular health, because blood pressure and ECG are physiologic...

AI Technical Summary

Problems solved by technology

[0007] However, ECG measurements performed with electrodes placed on the surface of the strap have some disadvantages

Since the contact between the skin and the electrodes is highly dependent on the degree of inflation of the cuff, i.e. the change that must occur during the blood pressure measurement, it is quite difficult to achieve a stable contact with the skin in this situation, Therefore, the accuracy of the measurement results may be questioned

[0008] In addition, when the general contact ECG electrode is in contact with the skin, there is also the problem that it is not easy to achieve stable contact between the contact surface and the skin, especially the planar contact electrode, as described in US Patent No. 5,713,365. The corresponding design is carried out for the contact parts, which are more prone to slipping and insufficient contact surface.
