Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to an electrocardiogram lead device, a ring and its detection system. Background Technology

[0002] Wearable devices like the ECG Holter monitor are popular among users and already offer monitoring functions such as heart rate and blood oxygenation. However, existing wearable devices still have limitations in meeting the long-term need for human electrocardiogram (ECG) monitoring. Common portable ECG monitoring devices, such as the ECG Holter monitor, mostly only support lead I or require an external lead cable to achieve multi-lead measurement. While smart wearable devices like the Apple Watch support ECG monitoring, they typically only support lead I. Although lead I can obtain some information, such as atrial fibrillation, the diagnosis of many heart diseases requires multi-lead data. Therefore, developing a wearable device that can perform multi-lead human ECG monitoring is of great significance. Utility Model Content

[0003] To address the aforementioned technical problems, this application provides an electrocardiogram (ECG) lead device, a ring, and a detection system thereof.

[0004] In the first aspect, this utility model proposes an electrocardiogram (ECG) lead device. The device has a ring structure with an internal mounting cavity. An integrated MCU module, an ECG front-end chip, a first lead post, and a second lead post are fixed in the mounting cavity. A second electrode is provided on the outer ring of the ring structure. The first lead post and the second lead post are respectively connected to human skin through the inner ring sidewall of the ring structure, forming a first electrode together. The first electrode and the second electrode are electrically connected to the MCU module through the ECG front-end chip.

[0005] The above technical solution integrates multiple components through a ring structure, achieving a compact and efficient ECG lead design that is convenient for wearing and signal acquisition and transmission, and can be widely used in various ECG monitoring scenarios.

[0006] Furthermore, the outer ring of the ring structure is a metal shell, which serves as the second electrode. The metal shell, acting as the lead medium, possesses excellent conductivity and stability, effectively transmitting ECG signals. Its outer ring design facilitates contact with different parts of the body to form lead circuits, ensuring the accuracy and reliability of ECG monitoring.

[0007] Furthermore, a collection port is provided on the inner sidewall, through which the first and second lead posts are connected to the human skin. The collection port design allows the lead posts to make precise contact with the skin, facilitating efficient acquisition of ECG signals, reducing signal loss and interference, and improving the quality and efficiency of signal acquisition.

[0008] Furthermore, the inner ring is made of a curable resin material. This curable resin material allows for easy fixation of internal components during assembly, provides excellent insulation protection, and ensures the overall comfort and durability of the ring, which is beneficial for long-term stable ECG monitoring.

[0009] Furthermore, the surfaces of the first lead post, the second lead post, and / or the metal housing are coated with a conductive film. This conductive coating further enhances the conductivity of each electrode component, reduces the impedance of signal transmission, ensures that ECG signals can be acquired and transmitted more clearly and accurately, and improves the overall ECG monitoring accuracy of the device.

[0010] Furthermore, the MCU module can be either DA14592 or nRF52840. Using either the DA14592 or nRF52840 MCU leverages its low power consumption and high performance to effectively control the acquisition, processing, and transmission of ECG signals, meeting the needs of wearable devices for long battery life and complex data processing, and ensuring stable device operation.

[0011] Furthermore, the ECG front-end chip uses either the MAX86176 or AFE4900 model. The MAX86176 or AFE4900 ECG front-end chip can perform high-precision amplification, filtering, and other preprocessing operations on weak ECG signals, effectively removing various interference signals and providing a high-quality ECG data foundation for subsequent accurate signal analysis and diagnosis.

[0012] Furthermore, the bottom of the first and second lead posts are provided with soldering parts, and the circuit board is correspondingly provided with first and second solder pad positions. This correspondence between the soldering parts and the solder pad positions ensures a stable connection between the lead posts and the circuit board, guaranteeing the stability and reliability of signal transmission and reducing the risk of signal abnormalities or interruptions due to loose connections.

[0013] Furthermore, the circuit board is equipped with a third solder pad, through which the metal casing is soldered to the circuit board for electrical connection. This soldering connection between the metal casing and the circuit board ensures a good electrical connection between the second electrode and the entire circuit system, optimizes the conduction path of the ECG signal, improves the efficiency and quality of signal transmission, and is beneficial for accurate ECG monitoring.

[0014] Secondly, this utility model proposes an electrocardiogram (ECG) detection system, which includes a receiving terminal and an ECG lead device described in the first aspect. The MCU module is connected to the receiving terminal through a communication module. The ECG signals collected by the first electrode and the second electrode are transmitted to the receiving terminal in sequence through the ECG front-end chip and the MCU module.

[0015] The above technical solution constructs a complete electrocardiogram (ECG) monitoring system, realizing an integrated process from signal acquisition and processing to display and analysis at the receiving terminal. This allows users to obtain and view ECG data in a timely manner, providing a convenient and efficient solution for heart health monitoring and disease diagnosis.

[0016] Thirdly, this utility model proposes an electrocardiogram (ECG) lead ring, which adopts the ECG lead device described in the first aspect and / or the ECG detection system described in the second aspect, wherein the ring structure is a finger ring structure.

[0017] Compared with the prior art, the beneficial results of this utility model are as follows:

[0018] 1. It adopts a ring design, which is small and easy to wear. No complicated lead wire connection is required. It can be used at any time in various daily activities. It is simple to operate and easy for both ordinary users and professionals to use.

Overcoming the limitations of single-lead monitoring, it can monitor lead I, other limb leads, and chest leads, reflecting cardiac electrical activity from multiple dimensions, providing more comprehensive ECG information, meeting the diagnostic needs of various heart diseases, and has strong versatility.

[0020] 3. Unique electrode structure: The combination of dry, small-area cylindrical electrodes and outer surface electrodes of the ring ensures good contact and reduces interference. Combined with a high-performance ECG front-end chip and MCU, it can accurately amplify, filter, analyze and process ECG signals, improve signal quality and accuracy, and reduce the risk of signal instability.

This system is designed with sufficient flexibility to be compatible with and adapt to different models of MCU and ECG front-end chips in order to achieve more optimized system performance and a wider range of application scenarios.

[0036] Application Example 1

[0037] During use, the ring-type lead is worn on the finger, with two lead posts contacting the skin on either side of the finger to form an electrode that connects to the body. When performing an electrocardiogram (ECG) test, lightly touching the metal casing with a finger of the other hand connects the casing to the body, creating a second ECG lead electrode. These two electrodes form lead I, enabling the detection of ECG data.

[0038] Application Example 2

[0039] In use, the ring-shaped lead is worn on the finger, with the two lead posts contacting the flesh on either side of the finger, thus forming an electrode that connects to the body. When the metal casing contacts the ankle of the lower limb, the metal casing connects to the body, forming a second ECG lead electrode. These two leads can then be used to create other limb leads (leads II and III), thereby enabling the detection of the body's electrocardiogram data.

[0040] Application Example 3

[0041] During use, the ring-type lead is worn on the finger, with two lead posts contacting the skin on either side of the finger, thus forming an electrode that connects to the body. When the metal outer shell contacts the outer side of the heart in the chest, it connects to the body, forming a second ECG lead electrode. These two leads together form a chest lead, enabling the detection of the body's electrocardiogram (ECG) data.

[0042] This application employs a ring-type design, pre-positioning one of the ECG leads in a dry, small-area columnar shape on the inner side of the ring, while the outer surface of the ring serves as the electrode for the other ECG lead. In practical applications, when the ring is worn on the finger of one hand and the other hand touches the surface of the ring, it enables ECG monitoring of lead I. When the outer surface of the ring contacts the ankle of the lower limb or the outer side of the heart in the chest, it enables ECG monitoring of other limb and chest leads, thus constructing a multi-lead ECG monitoring system and providing comprehensive and effective data support for the accurate assessment of cardiac health.
