Description

Technical Field

[0001] The present invention relates to the field of wearable electrocardiogram (ECG) health detection technology, and in particular to a novel method and system for electrocardiogram (ECG) monitoring using a smart wristband that is detachable, usable 24 hours a day, and can be used during sleep. Background Art

[0002] Electrocardiogram is the simplest, fastest and most economical clinical tool for diagnosing cardiovascular diseases and is considered the cornerstone of cardiovascular testing.

[0003] Traditional electrocardiograms (ECGs) performed in hospitals have limitations in detecting sudden and transient arrhythmias and atrial fibrillation, primarily due to their short recording time (seconds to minutes). These events are often triggered by unpredictable factors and may not occur within the scheduled examination timeframe, making them easily missed.

[0004] In order to increase the chance of capturing these "sudden and transient" arrhythmia events, doctors often recommend the use of 24-hour dynamic electrocardiogram (Holter monitoring) or wearable ECG monitors to increase the possibility of detecting "sudden and transient" arrhythmias and atrial fibrillation, providing more information for diagnosis.

[0005] Since its first application for cardiac electrophysiological monitoring by Holter in 1957, dynamic electrocardiography (DCG), also known as Holter monitoring, has become a key noninvasive cardiovascular examination tool. DCG can continuously record cardiac activity for over 24 hours, encompassing patients in various states, including rest, activity, dining, work, study, and sleep. This helps capture non-sustained arrhythmias that are difficult to detect with conventional ECGs, significantly improving the detection rate of transient arrhythmias and transient myocardial ischemic attacks. It provides important objective evidence for disease assessment, diagnosis, and therapeutic efficacy assessment.

[0006] However, traditional 24-hour Holter monitoring only obtains data after the patient has completed the 24-hour monitoring period. This makes data inefficient and can only be used for post-analysis. Furthermore, 24-hour Holter monitoring requires wearing a large number of electrodes, which is uncomfortable and can seriously affect the patient's sleep.

[0007] With the rise of Internet of Things (IoT) and artificial intelligence (AI), wearable ECG monitoring devices are widely used, including wearable ECG monitoring cards, wearable ECG monitoring watches, wearable ECG monitoring smart bracelets, and rings.

[0008] However, existing wearable ECG monitoring bracelets require both hands to touch two electrodes simultaneously when checking the ECG limb leads. When using an ECG monitoring watch, one needs to place one hand on the electrodes on the smartwatch's bezel. This method of checking is not suitable for people to use while sleeping, nor can it allow people to monitor for long periods of time to collect 24-hour ECG data. Summary of the Invention

[0009] The main purpose of the present invention is to propose a novel detachable smart bracelet ECG monitoring method and system, aiming to solve the problems in the existing technology that wearable ECG monitoring requires both hands to touch two electrodes at the same time, cannot monitor for a long time, and cannot perform ECG monitoring during sleep.

[0010] To achieve the above objectives, the present invention provides a novel detachable smart bracelet ECG monitoring method and system. The specific solution is as follows:

[0011] A novel detachable smart bracelet ECG monitoring method and system includes three independent and separate smart bracelets, namely main bracelet 1 (on the left wrist), sub-bracelet 2 (on the right wrist), and sub-bracelet 3 (on the left ankle).

[0012] The main bracelet 1 includes the following main components: an ECG detection module and a wireless voltage acquisition module. The wireless voltage acquisition module can collect the potential values collected by the electrodes on the main bracelet 1, and can also receive and collect the potential signals transmitted wirelessly by the sub-bracelets 2 and 3. The potential difference between the three bracelets is used to calculate the potential difference of ECG leads I, II, and III.

[0013] The main bracelet 1 includes supporting components: display screen, electrode-electrical signal acquisition module, Bluetooth communication module, battery module, etc.

[0014] Sub-bracelet 2 (right wrist) and sub-bracelet 3 (left ankle) generally include the following components: wireless voltage acquisition module, electrode-electrical signal acquisition module, Bluetooth communication module, battery module, etc.

[0015] According to the definition of standard ECG monitoring leads, lead I = L left wrist potential - R right wrist potential; lead II = F left ankle potential - R right wrist potential; lead III = F left ankle potential - L left wrist potential;

[0016] The potential difference between leads I, II, and III calculated dynamically can be displayed directly on the main bracelet's display screen or transmitted to a mobile phone APP platform via Bluetooth communication, instantly becoming the well-known P-QRS-T wave electrocardiogram.

[0017] The technical solution of this invention provides users with a novel detachable smart wristband ECG monitoring method and system. Its core innovation lies in the collection of potential information from multiple locations on the body through a wireless voltage acquisition module on the detached wristband. This information is then wirelessly transmitted to the main wristband for potential difference calculation, ultimately obtaining the ECG voltage difference value and forming the final ECG P-QRS-T waveform. This provides users with a new method and system for easy, hands-free ECG monitoring using a smart wristband, allowing for long-term use while sleeping at night. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] The solution provided by the embodiments of the present invention is to eliminate the need for users to simultaneously touch both electrodes of a wearable ECG monitoring device with both hands, or to place their other hand on the electrodes on the smartwatch's bezel when using an ECG monitoring watch. This provides users with a new method and system for easily and hands-free ECG monitoring using a smart wristband while sleeping or for extended periods of time.

[0037] Reference Figure 1 , Figure 1 Schematic diagram illustrating components of the main wristband 1 involved in an embodiment of the present invention.

[0038] In the subsequent description, suffixes such as "module," "component," or "unit" used to represent elements are only used to facilitate the description of the present invention and have no specific meaning. Therefore, "module," "component," or "unit" can be used interchangeably.

[0039] like Figure 1 As shown, the main bracelet 1 includes the main components: component 4-ECG detection module, component 3-wireless voltage acquisition module; the main bracelet 1 includes supporting components: component 5-electrode-electrical signal acquisition module, component 2-Bluetooth communication module, component 1-battery module, component 6-display module, etc.

[0040] like Figure 2 As shown, sub-bracelet 2 (right wrist) and sub-bracelet 3 (left ankle) generally include the following components: component 3-wireless voltage acquisition module, component 5-electrode-electrical signal acquisition module, component 2-Bluetooth communication module, component 1-battery module, etc.

[0041] like Figure 3 As shown in the figure, a novel detachable smart bracelet ECG monitoring method and system working principle diagram: the main bracelet 1 is placed on the user's left wrist, and the tightness is adjusted to maintain proper contact between the bracelet and the wrist skin; the sub-bracelet 2 is placed on the user's right wrist, and the tightness is adjusted to maintain proper contact between the bracelet and the wrist skin; the sub-bracelet 3 is placed on the user's left ankle, and the tightness is adjusted to maintain proper contact between the bracelet and the ankle skin;

[0042] The wireless voltage acquisition module can collect the potential values collected by the electrodes on the main bracelet 1, and can also receive and collect the potential signals transmitted wirelessly by the sub-bracelets 2 and 3. The potential difference of the three bracelets is used to calculate the potential difference of the ECG leads I, II, and III.

[0043] The specific calculation process can be based on the definition of the standard leads of ECG monitoring: Lead I = L left wrist potential - R right wrist potential; Lead II = F left ankle potential - R right wrist potential; Lead III = F left ankle potential - L left wrist potential.

[0044] The potential difference values of the above-mentioned I, II, and III leads calculated dynamically can be directly displayed on the display screen of the main bracelet, or transmitted to the mobile phone APP platform via Bluetooth communication for display, instantly becoming the well-known P-QRS-T wave electrocardiogram.

[0045] In the embodiment of the present invention, three bracelets can be placed on the left wrist, right wrist, and left ankle. In this way, the potential difference values of the three parts of the body are collected simultaneously, and an electrocardiogram with a traditional three-lead P-QRS-T wave can be formed, namely leads I, II, and III.

[0046] The embodiment of the present invention can also use two bracelets to be placed at two locations on the body at the same time, and collect the potential difference values of the two locations at the same time, so as to form a traditional single-lead P-QRS-T wave electrocardiogram. Specifically: the main bracelet 1 is placed on the left wrist, and the sub-bracelet 2 is placed on the right wrist, so that the potential difference of the single lead (lead I) can be calculated, lead I = L left wrist potential - R right wrist potential; the main bracelet 1 is placed on the right wrist, and the sub-bracelet 3 is placed on the left ankle, so that the potential difference of the single lead (lead II) can be calculated, lead II = F left ankle potential - R right wrist potential; the main bracelet 1 is placed on the left wrist, and the sub-bracelet 3 is placed on the left ankle, so that the potential difference of the single lead (lead III) can be calculated, lead III = F left ankle potential - L left wrist potential;

[0047] The technical solution of this invention provides users with a novel detachable smart wristband ECG monitoring method and system. Its core innovation lies in the collection of potential information from multiple locations on the body through a wireless voltage acquisition module on the detached wristband. This information is then wirelessly transmitted to the main wristband for potential difference calculation, ultimately obtaining the ECG voltage difference value and forming the final ECG P-QRS-T waveform. This provides users with a new method and system for easy, hands-free ECG monitoring using a smart wristband, allowing for long-term use while sleeping at night.
