Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to a high-sensitivity electrocardiogram monitor. Background Art

[0002] As a key means of assessing heart health, ECG monitoring plays a vital role in the medical field. From daily physical examinations and disease prevention screening to the diagnosis of heart disease patients, treatment process monitoring and recovery period tracking, ECG monitoring data provides doctors with an indispensable basis for diagnosis, helping to determine whether the heart rhythm is normal, whether the myocardium is ischemic and other key information, which is directly related to the accuracy and effectiveness of medical decisions.

[0003] At present, there are many types of ECG monitors on the market and the technology is constantly iterating. From traditional large-scale medical bedside ECG monitoring equipment to the gradually popular small-scale wearable ECG monitors for home use, significant progress has been made in signal acquisition, processing and portability. For example, the application of new electrode materials has improved the initial signal acquisition quality, and advanced digital signal processing algorithms can suppress some interference signals to a certain extent, making the analysis of ECG signals more accurate.

[0004] During human breathing, the chest cavity will rise and fall regularly, and this fluctuation will cause the ECG monitoring electrode patch attached to the surface of the chest skin to move. When the electrode patch is displaced, its contact state with the skin is constantly changing, and the contact resistance fluctuates accordingly. The ECG signal itself is extremely weak, usually at the microvolt level. The unstable change of the electrode patch contact resistance will introduce additional noise, which seriously interferes with the acquisition of the original ECG signal, causing the monitored ECG waveform to be distorted and the baseline drifts, which greatly affects the accurate identification and analysis of the key features of the ECG signal, thereby reducing the detection sensitivity and accuracy.

[0005] The chest fluctuation caused by breathing changes the relative position and distance between the electrode patch and the heart, affecting the coupling efficiency of the ECG signal from the heart to the electrode patch. In different breathing stages, such as chest expansion during inhalation, the distance between the electrode patch and the heart increases relatively, and the ECG signal attenuates more during the transmission process; the opposite is true during exhalation. This dynamic change in signal coupling makes the amplitude of the collected ECG signal unstable, which is prone to errors when measuring key parameters such as heart rate calculation and arrhythmia analysis. Therefore, a high-sensitivity ECG monitor is proposed to solve the above-mentioned problems. Summary of the invention

[0006] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a high-sensitivity ECG monitor, which solves the problem that the chest fluctuation caused by breathing changes the relative position and distance between the electrode patch and the heart, making the amplitude of the collected ECG signal unstable and prone to errors.

[0009] Preferably, a patch is connected to the electrode sheet, and the patch is provided with openings corresponding to the electrode one and the electrode two.

[0010] Preferably, the monitoring part includes a fan-shaped plate, which is fixedly connected to the outer wall of the electrode sheet, and two limit rods are slidably connected to the fan-shaped plate, and the ends of the two limit rods are fixedly connected to compensation blocks.

[0011] Preferably, the protection part comprises a shielding cover, the shielding cover is fixedly sleeved on the outer wall of the electrode sheet, the inner wall of the shielding cover is connected with a sound insulation layer, and the material of the sound insulation layer is sound-absorbing cotton.

[0012] Preferably, the end fixing sleeve of the electrode sheet is provided with a wire threading rack, an insulating head is installed on the fan-shaped plate, a wire is electrically connected to the photosensitive sensor, and the movable end of the wire is movable through the mounting hole, the fan-shaped plate, the insulating head and the wire threading rack in sequence.

[0013] Preferably, two tension springs are elastically connected between the inner arc surface of the compensation block and the outer wall of the shielding cover, the two tension springs are symmetrically and tilted relative to each other, a clamp is installed on the top of the fan-shaped plate, and the outer wall of the through end of the wire is clamped on the clamp.

[0014] Preferably, the control unit includes a chassis, which is arranged on the back of the ECG monitor body, a shielding net is fixedly connected between the outer wall of the chassis and the back of the ECG monitor body, and a heat dissipation hole is opened on a side of the chassis close to the ECG monitor body.

[0017] (III) Beneficial effects Compared with the prior art, the present invention provides a high-sensitivity electrocardiogram monitor, which has the following beneficial effects: 1. This high-sensitivity ECG monitor uses a photosensitive sensor in the monitoring unit to be electrically connected to the electrode. When the patient breathes, the rise and fall of the chest drives the compensation block to move, causing the distance and angle between the photosensitive sensor and the skin to change. The change in the amount of received light generates different electrical signals. The built-in ADC microcontroller can determine the respiratory state by processing the signals of these photosensitive sensors. The ECG acquisition module collects ECG data and classifies the ECG data according to the results of the respiratory state judgment. This helps doctors observe the changes in the patient's ECG data under different respiratory states, and more accurately analyze key parameters such as heart rate calculation and arrhythmia analysis, reducing errors caused by unstable ECG signal amplitude due to breathing.

[0018] 2. This high-sensitivity ECG monitor uses classified ECG data to be transmitted to the ECG monitor body for display and comparison. Doctors can intuitively view the differences in ECG data at different breathing stages and more accurately judge the patient's heart health status. This improves the accuracy of ECG monitoring and provides a more reliable basis for medical decision-making. It plays an important role in disease diagnosis, treatment process monitoring, and recovery period tracking, and improves the overall quality of medical services.

[0019] 3. The high-sensitivity electrocardiogram monitor uses the electrocardiogram monitor to set double electrodes at the same position for dual monitoring, which improves the monitoring accuracy. At the same time, the design of the monitoring part can adaptively synchronize the electrocardiogram monitoring with the patient's breathing undulation. The compensation block is elastically connected to the shielding cover through a tension spring. The tension of the tension spring makes the compensation block fit the patient's skin in real time and move with the breathing undulation, reducing the change in contact resistance caused by the displacement of the electrode patch due to breathing. This effectively avoids the introduction of additional noise and prevents phenomena such as distortion and baseline drift of the monitored electrocardiogram waveform, improving the ability to accurately identify and analyze the key features of the electrocardiogram signal.

[0020] 4. For the high-sensitivity electrocardiogram monitor, the shielding cover of the protection part is made of aluminum material, which can effectively resist electromagnetic interference. The sound-absorbing cotton sound insulation layer on its inner wall can reduce environmental noise, further stabilize the acquisition process of the electrocardiogram signal, ensure that the acquired signal is purer, reduce the influence of external interference on the electrocardiogram signal, and provide a reliable data basis for subsequent analysis and diagnosis.
