Description
Technical Field
[0001] This utility model relates to health monitoring equipment, and more particularly to a monitoring instrument that combines electrocardiogram and heart sound monitoring. Background Technology
[0002] In the field of healthcare, the high incidence, sudden onset, and high risk of heart disease make accurate and timely monitoring of the heart crucial. Currently, while cardiac monitoring technology is constantly developing, many shortcomings still exist.
[0003] As disclosed in patent application number 202110266964.0, the portable heart sound and electrocardiogram stethoscope, while achieving the function of acquiring and uploading heart sound and electrocardiogram signals to a certain extent and possessing a certain degree of innovation, also has some limitations. This stethoscope lacks a display module, preventing users from directly and intuitively obtaining heart sound and electrocardiogram data on the device. Viewing the data requires the use of a mobile phone or cloud server, which is extremely inconvenient for users in emergency situations or when external devices are unavailable. Furthermore, the stethoscope is small in size, and the two electrode pads are positioned too close together. In actual operation, this design is not conducive to accurate acquisition of electrocardiogram signals, as the acquisition effect is closely related to the placement of the electrode pads; excessively close proximity affects the accuracy and stability of the signal. Moreover, the close spacing between the electrode pads also inconveniences the operator, especially when monitoring patients with special body shapes or requiring precise positioning for data acquisition, increasing operational difficulty and reducing monitoring efficiency.
[0004] Existing ECG and heart sound monitoring devices also have many problems. Many ECG-related instruments struggle to acquire heart sound data simultaneously, making a comprehensive assessment of the heart's condition impossible. Some devices capable of acquiring both signals simultaneously are often bulky and complex, inconvenient to carry and operate, and fail to meet the need for on-the-go heart monitoring. Furthermore, existing devices either lack intuitive and clear data display or cannot present monitoring results in real time, affecting doctors' diagnostic efficiency and patients' timely understanding of their health status.
[0005] Therefore, it is urgent to develop a combined ECG and heart sound monitor that can overcome the above-mentioned shortcomings. This monitor should have an integrated display function, capable of displaying ECG and heart sound data in real time and intuitively. At the same time, while ensuring monitoring accuracy, it should be portable and easy to operate to meet the needs of different scenarios and provide stronger support for the prevention, diagnosis, and treatment of heart diseases.

[0031] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described in detail with reference to the embodiments.
[0032] Example 1
[0033] A combined ECG and heart sound monitoring device, comprising:
[0034] The housing 10 contains a main control board 11 and a display module 12 is mounted on the upper surface of the housing 10. In this embodiment, the display module 12 is an LED dot matrix display. In other embodiments, the display module 12 can also be a liquid crystal display. The display module 12 is connected to the main control board 11 and can be used to display electrocardiogram and heart sound data.
[0035] The auscultation head 13 is used to listen to heart sounds. The auscultation head 13 is installed on the lower end face of the housing 10 and connected to the main control board 11 through a line. The main control board 11 collects audio signals through the auscultation head 13, processes them and displays them on the display module 12. The auscultation head 13 can determine the intensity, rhythm and timing of heart sounds to assess the functional state of the heart and display this assessment result on the display module 12.
[0036] The first electrode 14 and the second electrode 15 are respectively mounted at both ends of the housing 10 and connected to the main control board 11. The main control board 11 collects electrocardiogram (ECG) signals through the first electrode 14 and the second electrode 15, processes them, and displays them on the display module 12. The operator holds the first electrode 14 and the second electrode 15 with both hands to detect the weak electrical signals generated by the heart and transmits them to the main control board 11 for recording and analysis.
[0037] The housing 10 serves as the overall load-bearing structure, and the internal main control board 11 uniformly processes the audio signals collected by the stethoscope head 13 and the electrocardiogram signals collected by the first electrode 14 and the second electrode 15. The data is displayed through the display module 12, allowing people to see the monitoring data intuitively and simplifying the operation process.
[0038] The first electrode 14 and the second electrode 15 are respectively installed at both ends of the housing 10. The operator can simply hold the device with both hands to complete the ECG signal acquisition. The operation is simple and easy to learn. At the same time, the stethoscope head 13 is installed on the lower end face of the housing 10. Its position is clear and easy to use. The overall design conforms to human operating habits.
[0039] The lower end of the housing 10 protrudes downward to form the stethoscope head 13. A through hole is provided at the center of the stethoscope head, which connects to the housing 10. An audio acquisition module 111 is installed on the main control board 11. The audio acquisition module 111 is directly opposite the through hole. A groove is provided on the end face of the stethoscope head. A diaphragm 134 is installed in the groove. The vibration of the diaphragm 134 transmits the sound signal to the audio acquisition module 111 through the through hole. The audio acquisition module 111 receives the sound signal and converts it into an electrical signal. The main control board 11 then processes and analyzes the electrical signal.
[0040] The housing 10 has two electrode terminals 112, each with a window 113. A first electrode 14 and a second electrode 15 are attached to their respective electrode terminals 112 and cover the windows 113. The wiring on each electrode terminal 14 and 15 is connected to the main control board 11 through their respective windows 113. When using the monitor, the user holds the first electrode 14 and the second electrode 15 with both hands. The weak electrical signals generated by the heart are transmitted to the skin surface. The first electrode 14 and the second electrode 15 collect these signals and transmit them through the wiring on their respective electrodes to the main control board 11 inside the housing 10 via the windows 113. The main control board 11 then processes and analyzes these electrocardiogram (ECG) signals. The windows 113 on the electrode terminals 112 provide a convenient channel for connecting the wiring of the first electrode 14 and the second electrode 15. The electrode sheet is attached to the electrode end 112 and covers the window 113. The installation method is simple and can ensure that the line is smoothly connected to the main control board 11, reducing the complex wiring process and lowering the equipment manufacturing and maintenance costs.
[0041] A stepped surface is formed between the electrode 112 and the housing 10. When the first electrode 14 and the second electrode 15 are mounted on the electrode 112, their end faces are flush with the end face of the housing 10. This flush design avoids discomfort caused by protruding or recessed electrode plates. When the operator holds the device with both hands, their palms can naturally conform to the housing, preventing discomfort caused by uneven electrode plates, making operation more comfortable and improving user convenience and comfort. The flush alignment of the electrode plates with the housing end face ensures full and close contact between the electrode plates and the skin, reducing unstable ECG signal acquisition due to poor contact. Stable contact enables more effective collection of weak electrical signals generated by the heart, improving the accuracy and reliability of ECG signal acquisition and providing strong support for accurate analysis of heart health.
[0042] The two electrode ends 112 are surrounded by a first electrode plate 14 and a second electrode plate 15, respectively, which greatly increases the contact area between the electrode plates and the human body. When the human body holds the electrode ends with both hands, more skin area can come into contact with the electrode plates, thereby collecting more comprehensive and richer electrocardiogram signals, significantly improving the integrity and accuracy of electrocardiogram signal acquisition, and providing more reliable data support for the accurate assessment of heart health.
[0043] A start button 16 is also installed on the upper surface of the housing 10. The start button 16 is connected to the main control board 11. From an ergonomic perspective, this layout fully considers the user's operating habits. The distribution of the start button 16, stethoscope head 13, and display module 12 allows the user to operate without significantly changing body posture or frequently shifting their gaze. For example, when performing cardiac monitoring, the user can maintain a relatively comfortable and natural standing or sitting posture, start the device, place the stethoscope head 13 on the chest, hold the electrode pads with both hands, and observe the display module, reducing fatigue caused by inconvenient operation and improving the user experience.
[0044] A battery 17 is also installed inside the casing 10. The battery 17 is connected to and supplies power to the main control board 11. A charging interface is installed on the main control board 11 that is exposed outside the casing 10. The charging interface is used to charge the battery 17.
[0045] The main control board 11 is also equipped with at least one of the following modules: Bluetooth, Wi-Fi, Zigbee, LoRaWAN, and 5G. In this embodiment, the main control board 11 is equipped with both Bluetooth and Wi-Fi modules; in other embodiments, it may be either of these two modules. The operator's mobile device can establish a wireless connection with the monitor via Bluetooth or Wi-Fi, and the data monitored by the monitor can be directly displayed on the mobile device for easy observation.

[0047] Example 2 is basically the same as Example 1, except that a Zigbee module is also installed on the main control board 11.
[0048] Example 3
[0049] Example 3 is basically the same as Example 1, except that a LoRaWAN module is also installed on the main control board 11.
