Embodiment Construction

[0027] The examples of the embodiment will now be described in detail in the drawings.

[0028] image 3 A data acquisition system 10 for obtaining an electrocardiogram signal from the patient 12 is shown. The data acquisition system 10 includes a 5 lead ECG main measurement unit 14 that measures an ECG signal from electrodes Ra, La, LL, and RL. It is well known that the pressurized AVR, AVL, and AVF are calculated by comparing the measurement voltage from each of the limb electrodes with the reference voltage. like image 3 As shown, amplifiers 16, 18, 20, and 22 are used to compare signals from each electrode with reference signals from the right arm electrode RA, and feed the output signal from each amplifier to the analog / digital converter 24. The amplifier 22 is the right leg drive (RLD) amplifier, and RLD uses the RL electrode to balance the human body and measure the potential of the electronic device. The A / D converter 24 converts an analog signal into a digital ECG sig...

Abstract

A data acquisition system for utilizing a scalable ECG electrode system. The data acquisition system includes a main unit and one or more expansion units for increasing the number of ECG leads applied to a patient to enhance monitoring capabilities. Embodiments are shown for providing a common mode signal between the main electrode unit and the extension unit without physically transferring a voltage potential between the main unit and the extension unit. In one embodiment, the main unit and the extension unit share a common ground reference potential. In a second embodiment, an optical signal is transmitted between the main unit and the extension unit to relay common mode information, while in a third embodiment a common electrode potential is provided to the main unit and the Both extend the units to build their own common reference signal.

Description

[0001] Cross-reference [0002] The priority of U.S. Patent Application No. 15 / 059, 922, filed on March 3, 2016, the full text of the patent application is incorporated herein by reference. Background technique [0003] The present disclosure generally relates to wireless ECG equipment. More specifically, the present disclosure relates to a technical solution for modular expansion of wireless ECG devices. [0004] ECG (ECG) Measures the electrical activity of the heart. It depicts the rate and regularity of heartbeats, as well as heart disease or damage, arrhythmia, etc. ECG is one of the most important non-invasive diagnostic tools available to heart disease experts. ECG was measured by placing the electrodes on the chest and the body of the patient and measured by the heart generated by the heart. The electrodes attached to the patient are connected to the ECG monitor or wirelessly communicate with the ECG monitor for further signal processing. [0005] A standard method for obta...
