Description

Technical Field

[0001] This utility model relates to the field of electrocardiogram (ECG) acquisition technology, and in particular to an ECG acquisition device. Background Technology

[0002] The existing ECG acquisition device has a relatively complex installation structure. Due to the high-intensity use of ECG acquisition devices, the failure rate and component damage rate are also relatively high, and maintenance is relatively frequent. The complex installation structure makes disassembly and assembly operations during maintenance inconvenient. In addition, the high-intensity use of ECG acquisition devices can easily lead to internal overheating. The existing heat dissipation layout is difficult to dissipate heat sufficiently, resulting in unsatisfactory heat dissipation effect and low heat dissipation efficiency.

[0003] A Chinese patent discloses an "electrocardiogram (ECG) device" with application number "CN201921723003.2". This portable ECG device improves its battery life by placing an isolation circuit board at the front. After the battery is fully charged, there is no energy loss due to the isolation circuit board, thus improving battery capacity utilization. This portable ECG device can have a long battery life without sacrificing portability, allowing for extended use by patients and assisting doctors in diagnosing conditions. However, the structure of this ECG acquisition device is difficult to disassemble, causing trouble for maintenance and repair. Furthermore, the limited internal heat dissipation space and single-direction heat dissipation lead to insufficient heat dissipation and limited heat dissipation efficiency, thereby affecting the lifespan of the ECG acquisition device.

Detailed Implementation

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1 and Figure 2 This utility model discloses an electrocardiogram (ECG) acquisition device, comprising a base shell 1. Anti-slip pads 15 are fixedly connected to the lower surface of the base shell 1, located at the four corners of the base shell 1. A display 21 is fixedly connected to the upper surface of the base shell 1. An upper fan 23 is fixedly connected to the upper inner wall of the base shell 1, located at the center of the upper inner wall. A lower fan 22 is fixedly connected to the lower inner wall of the base shell 1, located at the center of the lower inner wall. First heat dissipation windows 3 are provided at both the front and rear ends of the base shell 1. The first heat dissipation windows 3 are equipped with... The first heat-conducting sheet 2 and the base shell 1 are provided with snap-fit ​​holes 4 at both the front and rear ends. The left and right ends of the base shell 1 are fitted with encapsulation side plates 13. The rear surface of the encapsulation side plate 13 is fixedly connected with a snap-fit ​​strip 9 and a temperature sensor 14. The snap-fit ​​strip 9 is symmetrically distributed on the left and right ends of the encapsulation side plate 13. The side surface of the snap-fit ​​strip 9 is fixedly connected with a snap-fit ​​block 8, which snaps into the snap-fit ​​hole 4. The encapsulation side plate 13 is provided with a rectangular sleeve hole 10 and a second heat dissipation window 12. The second heat dissipation window 12 is located on the left and right sides of the rectangular sleeve hole 10. The second heat dissipation window 12 is provided with a second heat-conducting sheet 11.

[0027] Specifically, when disassembling the ECG acquisition device, first press the locking block 8, which is locked in the locking hole 4 of the base shell 1, to disengage the locking block 8 from the locking hole 4. This releases the locking fixation between the encapsulation side plate 13 and the base shell 1, allowing the encapsulation side plates 13 at both ends of the base shell 1 to be quickly removed from inside the base shell 1. Then, the integrated board 7 and internal components inside the base shell 1 can be inspected, replaced, and troubleshooted. After the inspection, replacement, and troubleshooting are completed, reassembly is required, and the locking block 8 is re-engaged. Hole 4 is used to snap the package side plate 13 into place on the left and right ends of the base shell 1. In addition, temperature sensor 14 monitors the temperature inside the base shell 1. When the temperature exceeds the set standard, the upper fan 23 blows air from above to cool the integrated board 7. Together with the first heat dissipation window 3 and the first heat conduction plate 2, the main heat in the upper space is dissipated. The lower fan 22 blows air from below to cool the integrated board 7. Together with the second heat dissipation window 12 and the second heat conduction plate 11, the main heat in the lower space is dissipated.

[0028] Reference Figure 1 , Figure 3 and Figure 4 Integrated plate 7 is fixedly connected to the inner side wall of the base shell 1. Integrated plate 7 is located directly below the upper fan 23 and directly above the lower fan 22. The upper surface of integrated plate 7 is provided with signal conditioning module 16, analog-to-digital conversion module 18, processing unit 19 and data management module 20. The analog-to-digital conversion module 18 is connected to the signal conditioning module 16, the processing unit 19 is connected to the analog-to-digital conversion module 18, and the data management module 20 is connected to the processing unit 19. The lower surface of integrated plate 7 is fixedly connected with connector 17, which is connected to the signal conditioning module 16. Connector 17 is connected to electrode 5 through signal line 6. Processing unit 19 is connected to display 21. Connector 17 is sleeved with rectangular sleeve hole 10.

[0029] Specifically, electrodes 5 are placed on the limbs and chest of the body. By capturing potential changes through contact with the skin, the electrical signals of the heart are obtained. The electrical signals are transmitted to the signal conditioning module 16, which contains an amplifier and a filter. The amplifier amplifies the microvolt-level electrical signals into analog signals, and the filter eliminates power frequency interference. The analog signals are transmitted to the analog-to-digital converter module 18, which converts the conditioned analog signals into digital signals through a high-precision ADC. The digital signals are transmitted to the processing unit 19, which performs algorithmic processing on the digital signals. The real-time waveform is displayed on the display 21.

[0030] Working principle: The ECG acquisition device is used for ECG monitoring with a sampling rate of 512Hz. The interface is USB and the data format is binary. It can perform filtering, QRS wave detection, and heart rate variability analysis. It is mainly used for real-time display of ECG, heart rate variability (HRV) analysis, arrhythmia detection, and health assessment based on ECG signals. The ECG acquisition device is connected to the body through electrode 5. The signal conditioning module 16 receives the electrical signal from the heart and amplifies it. The analog-to-digital conversion module 18 converts the conditioned analog signal into a digital signal and transmits the digital signal to the processing unit 19. The processing unit 19 performs algorithm processing on the digital signal, and the display 21 displays the ECG waveform in real time.
