[0014] The present invention has the following beneficial effects: When the present invention needs to place the ECG lead wire into the interior of the semicircular groove, the upper slide plate is pushed to move toward the end of the limiting plate. When the upper slide plate moves, the connection between the telescopic rod and the rectangular frame pushes the moving frame to slide on the surface of the limiting plate. At the same time, when the upper slide plate moves, it pushes the triangular plate to move toward the outer end of the triangular groove through the bent frame. At the same time, the upper slide plate can be twisted to rotate at the bottom of the telescopic rod. At this time, when the moving frame is reset by the elasticity of the elastic rod, the upper slide plate will not contact the top of the lower slide plate. After the ECG lead wire is placed in the interior of the semicircular groove, the upper slide plate is twisted to rotate and reset. At this time, the moving frame will use the elasticity of the elastic rod to push the upper slide plate to contact the top of the lower slide plate, and the surface of the triangular plate will also contact the inner wall of the triangular groove to limit the upper slide plate, thereby improving the convenience of placing the ECG lead wire in the semicircular groove. At this time, pushing the upper slide plate and the lower slide plate to move can sort out the ECG lead wires that are entangled together, help medical personnel quickly connect the ECG lead wires, avoid connection errors, ensure the effects of the ECG machine and ECG monitoring, and improve the safety of patients receiving examinations.

[0015] When the temperature is low, the present invention starts the heating wire to generate heat inside the heating frame, and the hot air generated by the heating wire enters into the inside of the through groove through the curved pipe, and the hot air in the through groove contacts the surface of the ECG lead wire through the circular hole, so as to soften the ECG lead wire and prevent the ECG lead wire from becoming stiff at low temperature and affecting the combing effect. When the shaft rod contacts the ECG lead wires that are entangled together, the shaft rod is forced to move toward the end of the lower slide plate through the linkage frame, and pushes the air pushing frame to move inside the air cylinder tube. The airflow generated when the air pushing frame moves is transmitted to the inside of the heating frame, and the airflow pushes the hot air in the heating frame into the inside of the semicircular groove to soften the ECG lead wire, and the shaft rod can push the ECG lead wires that are entangled together to separate.

[0016] When the shaft rod of the present invention moves, it drives the contact rod to contact the surface of the pressure plate. When the contact rod moves on the surface of the pressure plate, it pushes the inclined plate to rotate on the surface of the fixed ring. When the inclined plate expands, it pushes the expansion rod to move away from each other. When the expansion rod expands, it pushes the entangled ECG lead wires to quickly separate, thereby further improving the convenience of combing the ECG lead wires.

[0017] The present invention provides an arc plate inside the semicircular groove, a rolling rod arranged inside the arc plate and a vertical rod arranged at the end contact the surface of the ECG lead wire, the rolling rod and the vertical rod are used to limit the ECG lead wire, thereby improving the smoothness of the ECG lead wire when moving inside the semicircular groove and avoiding the ECG lead wire from getting stuck due to the large friction between the ECG lead wire and the inner wall of the semicircular groove.

At the same time, the P wave morphology changes on the ECG monitor are monitored in real time to look for characteristic high-amplitude positive P waves; If the expected P wave change occurs, the depth of the current catheter is recorded and used as the target position of the PICC tip. The expected P wave is a high-amplitude positive P wave. If the expected P wave changes do not occur, the catheter position is readjusted so that the catheter tip enters the lower 1 / 3 of the superior vena cava, close to the junction of the superior vena cava and the right atrium, and a high-amplitude positive P wave can be displayed.

[0034] Those skilled in the art can understand that the auxiliary sliding plate + corresponding sensor for the ECG lead wire quick connection can make feedback judgment on the lead wire quick connection, and the curve graph of the electrical activity changes generated by each cardiac cycle of the heart recorded by the electrograph can be used to monitor atrial hypertrophy, ventricular hypertrophy, myocardial infarction, ectopic rhythm and other abnormal cardiac electrical activities. Only when the ECG leads are placed in the standard chest wall position can accurate examination results be obtained, plus the application of indications, such as "connecting the central venous catheter and the ECG monitor through the ECG lead wire can determine the position of the catheter tip. When the catheter tip enters the lower 1 / 3 of the superior vena cava near the junction of the superior vena cava and the right atrium, a high-amplitude positive P wave can be seen, which is the ideal position of the PICC tip. Based on the characteristic principle of the P wave, a sterile ECG lead wire set for detecting the puncture position of the PICC catheter is designed. During PICC catheterization, the specificity of the P wave is used to determine the position of the PICC tip, thereby improving the success rate of catheterization positioning. When the chest leads are connected in the wrong position, the ECG waveform will be abnormal. Specifically, since the chest leads are responsible for recording the electrical activity of different parts of the heart, when they are placed in the wrong position, the recorded electrical activity will no longer reflect the true state of the heart. This may cause changes in the amplitude, shape, and proportional relationship between waveforms such as the R wave and S wave, making the ECG waveform significantly different from the normal waveform. For example, if the position of the V1 and V2 leads is too high, it may cause ECG changes, and then pseudo-anterior wall old myocardial infarction or pseudo-incomplete right bundle branch block may occur. The reverse connection of the V2 and V3 leads may cause the V2 lead to show a transitional wave of V3, that is, a wave with R / S of 1, which may be misdiagnosed as cardiac ischemia or other heart diseases.

[0035] When in use, when it is necessary to place the ECG lead wire into the interior of the semicircular groove 4, push the upper slide plate 1 to move toward the end of the limit plate 13. When the upper slide plate 1 moves, the connection between the telescopic rod 10 and the rectangular frame 11 pushes the movable frame 12 to slide on the surface of the limit plate 13. At the same time, when the upper slide plate 1 moves, it will push the triangular plate 16 to move toward the outer end of the triangular groove 17 through the bent frame 15. At the same time, the upper slide plate 1 can be twisted to rotate at the bottom of the telescopic rod 10. At this time, when the movable frame 12 uses the elasticity of the elastic rod 19 to reset, the upper slide plate 1 will not contact the top of the lower slide plate 2. After the ECG lead wire is placed in the interior of the semicircular groove 4, the upper slide plate 1 is twisted to rotate and reset. At this time, the movable frame 12 will use the elasticity of the elastic rod 19 to reset. Push the upper slide plate 1 to contact the top of the lower slide plate 2, and the surface of the triangular plate 16 will also contact the inner wall of the triangular groove 17 to limit the upper slide plate 1, thereby improving the convenience of placing the ECG lead wires inside the semicircular groove 4. At this time, pushing the upper slide plate 1 and the lower slide plate 2 to move can sort out the ECG lead wires that are entangled together, helping medical personnel to quickly connect the ECG lead wires to avoid connection errors, ensuring the effects of the ECG machine and ECG monitoring, and improving the safety of patients undergoing examinations. When the temperature is low, start the heating wire 21 to generate heat inside the heating frame 25, and the hot air generated by the heating wire 21 will enter the inside of the through groove 29 through the curved pipe 20, and the hot air in the through groove 29 will pass through The circular hole 26 contacts the surface of the ECG lead wire to soften the ECG lead wire to prevent the ECG lead wire from becoming stiff at low temperature and affecting the combing effect. When the shaft 28 contacts the ECG lead wires that are entangled together, the shaft 28 is forced to move toward the end of the lower slide 2 through the linkage frame 27, and push the air pusher frame 22 to move inside the air cylinder tube 24. The airflow generated when the air pusher frame 22 moves will be transmitted to the inside of the heating frame 25. At the same time, the airflow will push the hot air in the heating frame 25 into the inside of the semicircular groove 4 to soften the ECG lead wire. At the same time, the shaft 28 can push the ECG lead wires that are entangled together to separate. When the shaft 28 moves, it drives the contact rod 43 to contact the surface of the pressure plate 41. When the contact rod 43 moves on the surface of the pressure plate 41, it will push the inclined plate 46 to rotate on the surface of the fixed ring 40. When the inclined plate 46 expands, it will push the expansion rod 44 to move away from each other. When the expansion rod 44 expands, it will push the ECG lead wires that are entangled together to quickly separate, further improving the convenience of combing the ECG lead wires. An arc plate 50 is arranged inside the semicircular groove 4. The roller bar 52 arranged inside the arc plate 50 and the vertical rod 54 arranged at the end are in contact with the surface of the ECG lead wire. The roller bar 52 and the vertical rod 54 are used to limit the ECG lead wire, thereby improving the smoothness of the ECG lead wire when it moves inside the semicircular groove 4 and avoiding the ECG lead wire from getting stuck due to the large friction between the ECG lead wire and the inner wall of the semicircular groove 4.

[0036] The design and implementation ideas of the multi-lead ECG monitoring system based on the capacitive coupling principle provided in this embodiment are as follows: 1. System design: Flexible capacitive electrode integration: multiple flexible capacitive electrodes made of conductive fabrics are integrated on the back of the chair seat to obtain 6-lead ECG signals including standard limb leads Ⅰ, Ⅱ, Ⅲ and pressurized unipolar limb leads aVR, aVL, aVF, which not only improves the contact effect with the human body surface, but also effectively reduces the generation of motion artifacts. Signal acquisition and processing: ECG signals are collected by capacitive coupling, and the signals are processed using algorithms such as adaptive filters to eliminate noise interference and improve signal quality.

[0037] 2. Identification of chest leads: a. Detection of lead wire connection status: During ECG monitoring, first of all, it is necessary to ensure that all lead wires are in good connection status. This can be achieved through a comparator circuit, which can detect whether the lead wire is detached and output a corresponding signal when the lead wire is detached. Although this step does not directly involve the identification of chest leads, it is the basis for ensuring the accurate collection of ECG signals. b. Waveform feature analysis: Once it is confirmed that all lead wires are connected normally, the collected ECG signals can be analyzed. By analyzing the ECG waveform features of different leads (including chest leads), such as P waves, QRS complexes, T waves, etc., chest leads can be indirectly identified. For example, the V1 lead is usually placed in the fourth intercostal space on the right edge of the sternum, and its waveform features may be different from other leads.

[0038] 3. Algorithm implementation: Empirical mode decomposition (EMD): Perform empirical mode decomposition on the RR interval sequence and EDR signal to obtain multiple intrinsic mode functions (IMFs). These IMFs reflect the different frequency components and change trends of the ECG signal. Among them, the decomposition process of EMD can be summarized as the following steps: Determine the extreme points: First, identify all local maximum and minimum points in the signal. Construct the envelope: Connect all the maximum and minimum points respectively through methods such as cubic spline interpolation to form the upper envelope and the lower envelope. Calculate the mean line: The mean of the upper envelope and the lower envelope is taken as the mean line, denoted as m(t). Extract the detail component: Subtract the mean line from the original signal to obtain a new signal h(t)=X(t)−m(t), where X(t) is the original signal. Iterative screening: If the new signal h(t) does not meet the IMF conditions, that is, it has the same number of maxima and minima, and the zero crossing points correspond to the extreme points, then use it as a new signal and repeat steps 1 to 4 until the extracted signal meets the IMF conditions. This iterative process is called a "screening" or "sieving" process. Iterative decomposition: Remove the extracted IMF from the original signal to obtain a residual signal. Repeat the above steps for the residual signal until the residual signal is a monotonic function or close to zero. Finally, the original signal is decomposed into several IMF components and a residual term. These IMF components reflect the different frequency components and changing trends of the ECG signal. Each IMF is independent of each other and has different frequency components and changing trends, which helps to more accurately understand and analyze the characteristics of the ECG signal.

[0039] 4. Correlation analysis: Using the correlation between the RR interval sequence and the EDR signal, the noise component in the EDR signal is eliminated through an adaptive filter to enhance the EDR signal. Pattern recognition: Further pattern recognition and classification are performed on the enhanced EDR signal to identify different types of arrhythmias, including arrhythmias associated with chest leads. In summary, by using flexible capacitive electrodes made of conductive fabrics, better contact with the human body surface can be achieved, effectively reducing the generation of motion artifacts. This means that even during movement or daily activities, a relatively stable ECG waveform can be obtained, thereby improving the quality of the ECG signal; the multi-lead ECG monitoring system based on capacitive coupling can obtain ECG signals of standard limb leads and pressurized unipolar limb leads, which helps to diagnose cardiac abnormalities more accurately, especially when precordial leads (such as V1-V6) can be used, which can further eliminate or reduce baseline drift and muscle artifacts, thereby improving the accuracy of ECG monitoring during cardiac catheterization and angiography; compared with traditional hard electrodes, flexible capacitive electrodes are more comfortable and reduce irritation and discomfort to the patient's skin. This is especially important for patients who require long-term dynamic ECG monitoring; the multi-lead ECG monitoring system based on capacitive coupling is not only suitable for personal daily ECG monitoring, but also for long-term dynamic ECG monitoring, providing more options and flexibility for clinical diagnosis.

[0040] In order to achieve the rapid unwinding and rapid disinfection of ECG lead wires, a moving slider is proposed to quickly unwind the lead wires and a method of using the same. The core of this embodiment is that the acquisition of capacitance is achieved by processing and amplifying the distributed capacitance sensor 62 of the guide and shielding wires. Specifically, the distributed capacitance sensor 62 used in this embodiment can be a parallel plate capacitor formula: 1. For a parallel plate capacitor, its capacitance C can be calculated by the following formula: , where ε is the dielectric constant, A is the plate area, and d is the plate spacing. In the ECG lead wire slide device, the distributed capacitance sensor 62 between the guide and shielding wires can be regarded as a special parallel plate capacitor structure. By measuring the relevant parameters and substituting them into the above formula, the size of the distributed capacitance can be estimated.

[0041] 2. Capacitor series formula: When multiple capacitors are connected in series, the reciprocal of the total capacitance Ctotal is equal to the sum of the reciprocals of each capacitor, that is: , C1, C2...Cn represent the capacitance values ​​of each capacitor connected in series.

[0042] In the ECG lead wire system, due to the existence of multiple connection points and line segments, distributed capacitance may exist in series. By measuring the capacitance value of each part, the total distributed capacitance can be calculated using this formula.

[0043] 3. Capacitor parallel formula: When multiple capacitors are connected in parallel, the total capacitance Ctotal is equal to the sum of each capacitor, that is: , C1, C2...Cn represent the capacitance values ​​of each capacitor connected in parallel.

[0044] In some cases, such as when multiple shielded wires are placed in parallel, the distributed capacitance between them may affect each other and form a parallel capacitance. In this case, this formula can be used for calculation. The capacitance calculation formula is C=Q / U, where Q is the charge, which refers to the amount of charge carried by the capacitive sensor. When the capacitive sensor is charged, its two plates will carry equal amounts of positive and negative charges respectively. The total amount of these charges is the amount of charge stored in the capacitor; U is the potential difference between the two plates of the capacitive sensor, that is, the potential difference, in volts (V).

[0045] The implementation principle of the above-mentioned method is as follows: Electrostatic induction principle: The acquisition of capacitance is based on the electrostatic induction principle. When there is a potential difference between two conductors, charge accumulation will occur on the surface of the conductor to form an electric field. In the ECG lead wire slide device, the guide and shield wires are two relatively independent conductors. Electrostatic induction will occur between them due to the potential difference, thus forming distributed capacitance. Electric field coupling principle: In addition to electrostatic induction, electric field coupling is also an important factor in generating distributed capacitance. When current passes through the wire, an alternating electric field will be generated around it. This electric field will couple with nearby wires or conductors, resulting in the redistribution of charge, thereby forming distributed capacitance. Signal transmission and detection principle: ECG signal is a weak bioelectric signal, and its frequency range is usually between 0.05Hz and 150Hz. In the ECG lead wire, distributed capacitance will have a certain impact on the ECG signal, such as signal attenuation, phase delay, etc. In order to accurately obtain the ECG signal, it is necessary to process and compensate for the distributed capacitance. By measuring the size of the distributed capacitance and using the corresponding circuit or algorithm to amplify and correct it, the acquisition accuracy and quality of the ECG signal can be improved.

[0046] The specific implementation steps are as follows: 1. Select appropriate materials and structures: According to the use requirements and environmental conditions of the ECG lead wire, select materials with appropriate dielectric constants and insulation properties to make guide and shield wires, as well as related insulation layers and shells. At the same time, design a reasonable wire structure and layout to reduce the influence of distributed capacitance. 2. Measure distributed capacitance: Use professional capacitance measuring instruments or circuits to measure the distributed capacitance between the guide and shield wires. The measurement methods can include direct measurement, resonance, AC bridge method, etc. By measuring multiple times and taking the average value, a more accurate distributed capacitance value can be obtained. 3. Design the amplifier circuit: According to the measured distributed capacitance value and the characteristics of the ECG signal, design the corresponding amplifier circuit. The amplifier circuit should have the characteristics of high input impedance, low noise, high gain, etc. to ensure that the ECG signal can be accurately amplified and other interference signals can be suppressed. Common amplifier circuits include in-phase amplifiers, inverting amplifiers, differential amplifiers, etc. 4. Calibration and debugging: Connect the designed amplifier circuit to the ECG lead wire, and calibrate and debug it. By inputting a known ECG signal or analog signal, adjust the parameters of the amplifier circuit so that the amplitude and phase of its output signal match the input signal. At the same time, check the stability and linearity of the amplifier circuit to ensure that it can work normally under different working conditions. 5. Integration and application: Integrate the calibrated and debugged amplifier circuit with other parts of the ECG lead slide device to form a complete ECG monitoring system. In actual use, the system should be inspected and maintained regularly to ensure its stable and reliable performance. The capacitive sensor is a very simple and stable sensor. The changes in the measured value can be reflected as changes in capacitance, which causes the output port to be implemented in the form of voltage or current changes. It can accurately measure pressure, displacement, thickness, vibration, instantaneous acceleration and other parameters. Capacitive sensors are suitable for contactless measurement, but the disadvantage is that they have certain nonlinearity.

[0047] In the development trend of mechatronics, it is very necessary to use sensor technology to achieve automatic control. The sensor automatically collects system data as input signals, and the single-chip microcomputer realizes automatic program control to achieve the goal of improving work efficiency.

[0048] This embodiment uses phototransistors to control the brightness of the LEDs of V1-V8. Phototransistors are the most common light sensors, i.e., photoelectric carriers. In addition to the function of photodiodes to convert light signals into electrical signals, phototransistors also have the function of amplifying electrical signals. It can be seen that phototransistors have higher sensitivity than photodiodes. Photoelectric sensors are sensors that use photoelectric elements as detection elements. It first converts the changes in the measured value into changes in the light signal, and then further converts the light signal into an electrical signal with the help of photoelectric elements. By collecting daylight data through phototransistors and controlling the current flowing through the LEDs, the recognition rate of the lead wires can be improved, and the probability of connecting the wrong lead wire ball head can be effectively reduced.

[0049] According to the basic requirements of the product in the embodiment, a Panasonic 18650BD imported 3200mah12v6400mah polymer LI-PO18650 lithium battery pack was customized. After carefully measuring the size of the overall device, a lithium battery pack with a size of 20X70X110mm was purchased according to the size of the sliding plate. When it is idle, it is placed on the wireless charger to immediately enter the charging state. The 12V power supply is directly used for the capacitive sensor and the active voice circuit.

[0050] For the circuit board power supply, the system supplies 12VDC to the circuit through a switching power supply. 12VDC is used for voice circuits and sensors, and 5VDC and 3.3VDC are used to power the LED chips in the circuit. The LM2596, a common voltage-stabilized power supply chip, is used, which can output a 3A drive current.

[0051] The lead wire quick separation device designed in the embodiment of the present invention is an innovation. Experimental results show that it can be used repeatedly and sustainably, and has a simple and practical effect in actual use. It has a significant effect on the lead wires that need to be quickly separated.
