The steel wire 22 provides a certain rigid support for the electrode catheter 21 during use, so as to avoid the electrode catheter 21 from failing to smoothly reach the right ventricle when the electrode catheter 21 passes through the reflux during use. The electrode conductor is provided with a cathode lead wire 13, an anode lead wire 14, a lead tail end interface 15, a syringe interface 16 and a line change controller 19. The lead tail end interface 15 is hollow. The steel wire 22 is implanted into the electrode catheter 21 through the lead tail end interface 15. The steel wire 22 is pushed to the tail end of the electrode catheter 21, and then pushed to the head end of the electrode catheter 21 from the inside. When the steel wire 22 is retained in the lead tail end interface 15, the electrode catheter 21 is in a straight state. At this time, the cathode lead wire 13 and the anode lead wire 14 are connected to an external temporary pacemaker, so that the first cathode electrode 1 and the first anode electrode 4 can be paced.The invention realizes cardiac pacing. At the same time, the pressure receptor 2 at the tip end of the electrode catheter 21 monitors the pressure and pacing impedance, and displays them through the pressure display 12, so as to timely identify whether the tip end of the electrode catheter 21 is dislocated, and avoid complications such as myocardial perforation caused by the tip end of the electrode catheter 21 falling off.

When the steel wire 22 is withdrawn, different gears can be adjusted by the line controller 19 until the heart is stably paced, so as to avoid the end of the electrode catheter 21 falling off due to the change of the patient's body position, so that the first cathode electrode 1 at the end of the electrode catheter 21 cannot effectively contact the myocardial chamber, and then lead to incomplete pacing. The cathode lead wire 13 is connected to the first cathode electrode 1 through a wire, and the anode lead wire 14 is connected to the first anode electrode 4 through a wire.

[0044] Working principle: When using the shaped floating temporary cardiac pacing electrode of the present invention, according to Figure 1 and Figure 2 , including the following steps:

[0045] Step 1: implant the steel wire 22 into the electrode catheter 21 through the wire tail end interface 15, the steel wire 22 is pushed to the tail end of the electrode catheter 21, and then pushed to the head end of the electrode catheter 21 from the inside. At this time, the electrode catheter 21 is in a straight state, so that the electrode catheter 21 has a certain rigid support when in use, and the electrode catheter 21 will not be pushed back due to backflow, ensuring that the electrode catheter 21 can smoothly reach the right ventricle.

[0046] Step 2: Pass the electrode catheter 21 through the right atrium to the apex of the right ventricle. When placing the electrode catheter 21, pump air into the electrode catheter 21 through the external syringe 20 to inflate the balloon 3 at the end of the electrode catheter 21 with air so that the electrode catheter 21 can flow along the blood flow.

[0047] Step three: monitor the pressure through the pressure sensor 2 at the same time, and display the monitoring results through the pressure display 12. If the displayed pressure is high, change or adjust the route of the electrode catheter 21 in time to ensure the pressure of the electrode catheter 21 when it is used, and avoid abnormal pressure affecting its use.

[0048] Step 4: When the electrode catheter 21 passes through the right atrium and reaches the apex of the right ventricle, the cathode lead wire 13 and the anode lead wire 14 are connected to an external temporary pacemaker, and ventricular pacing is performed by the temporary pacemaker. The gear position is adjusted by the variable gear controller 19 according to the situation of cardiac pacing, and different gear positions are adjusted until the heart is stably paced.

[0049] Step 5: When the electrode catheter 21 needs to be indwelled for a long time, the pressure sensor 2 monitors the pressure of the electrode catheter 21 indwelling for a long time, and if the pressure is high, the pressure is reduced in time.

[0050] In order to solve the problem of the existing patent that the electrode tip cannot pace normally when it reaches the right ventricle during use, please refer to Figure 3 , this embodiment provides the following technical solutions:

[0051] The steel wire 22 in the lead tail end interface 15 is pulled out. When the steel wire 22 is pulled out to the sixth electrode 10, the head end of the electrode catheter 21 presents a circular curved shaping state. The first electrode 5, the second electrode 6, the third electrode 7, the fourth electrode 8, the fifth electrode 9 and the sixth electrode 10 correspond to the positions of 2 o'clock, 5 o'clock, 8 o'clock and 11 o'clock of the ring respectively. When the electrode catheter 21 is in a ring shape, the second cathode electrode 17 and the second anode electrode 18 are connected to an external temporary pacemaker, and different gears are adjusted by the line controller 19 until the ventricle can be stably paced. Since the electrode catheter 21 needs to be implanted in the target part of the heart , and corresponds to the target part, and paces when needed. However, the electrode catheter 21 may be separated from the target position in the human body due to human activities. When the electrode catheter 21 is in a circular shape, it is equivalent to setting a pair of electrodes at the target position, and ventricular pacing is completed by a temporary pacemaker, providing more groups of electrodes and ventricular muscle contact options. Ventricular pacing is completed by switching different pacing electrode groups, avoiding the problem that the electrode group composed of the first cathode electrode 1 and the first anode electrode 4 cannot pace the ventricle when the head end of the electrode catheter 21 is dislocated, achieving multiple guarantees and ensuring the success rate of temporary cardiac pacing.

[0052] In summary, a shaped floating temporary cardiac pacing electrode of the present invention uses an external syringe 20 to pump air into an electrode catheter 21, and fills the balloon 3 at the end of the electrode catheter 21 with air, so that the electrode catheter 21 can flow along the blood flow. The provided steel wire 22 allows the electrode catheter 21 to have a certain rigid support when in use, so as to avoid the inability to smoothly reach the right ventricle when passing through reflux during use. When the steel wire 22 is retained in the lead tail end interface 15, the electrode catheter 21 is in a straight state. At this time, the cathode lead wire 13 and the anode lead wire 14 are connected to an external temporary pacemaker, which can pace the first cathode electrode 1 and the first anode electrode 4 to achieve cardiac pacing. At the same time, the pressure receptor 2 at the head end of the electrode catheter 21 monitors the pressure and pacing impedance, and through the pressure The force display 12 is used to display whether the tip of the electrode catheter 21 is dislocated, so as to avoid complications such as myocardial perforation caused by the detachment of the tip of the electrode catheter 21. The steel wire 22 in the interface 15 at the tail end of the wire is pulled out. When the steel wire 22 is pulled out to the sixth electrode 10, the tip of the electrode catheter 21 presents a circular curved shape. The second cathode electrode 17 and the second anode electrode 18 are connected to an external temporary pacemaker, and ventricular pacing is completed by the temporary pacemaker, providing more groups of electrode and ventricular muscle contact options. Ventricular pacing is completed by switching different pacing electrode groups, avoiding the problem that the electrode group composed of the first cathode electrode 1 and the first anode electrode 4 alone cannot pace the ventricle when the tip of the electrode catheter 21 is dislocated, achieving multiple protections and ensuring the success rate of temporary cardiac pacing.

[0053] Specifically, monitoring the pressure display operation quality of the pressure display includes:

[0054] Real-time acquisition of the moment when each pressure display value of the pressure display changes;

[0055] Using the change moment of each pressure display value change, the time interval between each two adjacent pressure value change displays is obtained;

[0056] The pressure display change coefficient is obtained according to the time interval between each two adjacent pressure value changes; wherein the pressure display change coefficient is obtained by the following formula:

[0057]

[0058] Where W is the pressure display change coefficient; n is the total number of time intervals; T max and T min Indicates the maximum and minimum values ​​corresponding to the time interval between two adjacent pressure value changes; T z Indicates the middle value of the time interval distribution; T i Represents the duration value corresponding to the i-th time interval;

[0059] When the change coefficient of the pressure display exceeds a preset coefficient threshold, the sensitivity value of the pressure sensor is retrieved;

[0060] The operating quality of the pressure display is determined according to the sensitivity value of the pressure sensor.

[0061] The technical effect of the above technical solution is: by real-time acquisition of the change moment of each pressure display value change of the pressure display, the working state of the pressure display can be quickly captured. Once the pressure display is found to be abnormal (that is, the change coefficient exceeds the preset coefficient threshold), the system can immediately issue an early warning, thereby allowing the operator to intervene in time and take corresponding measures.

[0062] Accurately evaluate the performance of pressure monitors: Using the time interval to calculate the coefficient of variation of the pressure monitor, the performance of the pressure monitor can be quantitatively evaluated. This quantitative evaluation not only improves the accuracy of the evaluation, but also provides data support for subsequent performance improvements.

[0063] Automatically retrieve sensitivity values: When the pressure display coefficient of variation exceeds the threshold, the system automatically retrieves the sensitivity value of the pressure sensor. This step helps to quickly locate the problem, whether it is a problem with the pressure display itself or the pressure sensor, thereby improving the efficiency of problem solving.

[0064] Improve surgical safety: In cardiac interventional surgery, the accuracy and safety of electrode catheter placement are crucial. By monitoring the operating quality of the pressure display in real time, the accuracy and stability of electrode catheter placement during surgery can be ensured, thereby improving the safety of the surgery.

[0065] Reduce operational risks: Since the system can promptly detect and warn of abnormal conditions of the pressure display, operators can adjust their operating strategies in a timely manner based on the warning information, reducing operational risks caused by equipment failure or operational errors.

[0066] Optimize user experience: By improving the stability and reliability of the equipment, the entire surgical process is optimized, the workload of operators is reduced, and the user experience is improved.

[0067] In summary, this monitoring solution improves the safety and reliability of surgery, reduces operational risks, and optimizes user experience by real-time monitoring and evaluating the operating quality of the pressure display.

[0068] Specifically, judging the operation quality of the pressure display according to the sensitivity value of the pressure sensor includes:

[0069] Extracting the sensitivity value of the pressure receptor (2);

[0070] Extracting the relative change value of the current corresponding to each time the pressure sensor (2) collects the pressure value;

[0071] The relative change value and the sensitivity value of the current are used to obtain the pressure value corresponding to each pressure sensor (2) sampling; wherein the pressure value is obtained by the following formula:

[0072]

[0073] Wherein, P represents the pressure value; P0 represents the pressure value corresponding to the pressure sensor (2) before the current pressure acquisition; ΔI represents the relative change value of the current, and when the relative change value of the current is a negative number, it means that the current value decreases, and when the relative change value of the current is a positive number, the current value increases; S represents the sensitivity value of the pressure sensor (2);

[0074] Using the pressure value, obtaining a parameter of the variation amplitude between two adjacent pressure values ​​collected by the pressure sensor (2);

[0075] Retrieve the pressure display variation coefficient;

[0076] The operation quality evaluation coefficient of the pressure display is obtained by using the change amplitude parameter between the pressure values ​​of each two adjacent data collections corresponding to the pressure sensor (2) and the pressure display change coefficient; wherein the operation quality evaluation coefficient is obtained by the following formula:

[0077]

[0078] Where K represents the operation quality evaluation coefficient; W represents the pressure display change coefficient; m represents the number of groups corresponding to each two adjacent data collections; P i represents the pressure change amplitude value corresponding to the i-th group of pressure acquisition; P i-1 represents the pressure change amplitude corresponding to the i-1th group of pressure acquisition; P fz Indicates the median value of the pressure change amplitude distribution state; P fmax and P fmin Indicates the corresponding maximum and minimum values ​​of the pressure change amplitude that occurs during the pressure acquisition process;

[0079] When the operation quality evaluation coefficient is lower than a preset operation quality coefficient threshold, it is determined that the pressure display has a display abnormality and an abnormality alarm is issued.

[0080] The technical effect of the above technical solution is that by combining the sensitivity value of the pressure receptor and the relative change value of the current to calculate the pressure value, the real-time pressure change can be more accurately reflected. This calculation method improves the accuracy and reliability of the data, thereby helping doctors or operators to more accurately evaluate the placement of the electrode catheter.

[0081] Real-time monitoring and evaluation: This technical solution can monitor the data collection of the pressure sensor in real time and calculate the pressure change amplitude parameter between each two adjacent data collections. This real-time monitoring and evaluation method enables operators to understand the operating status of the pressure display in a timely manner and make corresponding adjustments.

[0082] Comprehensive evaluation of operation quality: By combining the pressure display change coefficient and the pressure value change amplitude parameter collected by the pressure sensor, the operation quality evaluation coefficient of the pressure display is calculated. This comprehensive evaluation method can more comprehensively reflect the operation quality of the pressure display, including its stability and accuracy.

[0083] Abnormal warning and alarm: When the operation quality evaluation coefficient is lower than the preset operation quality coefficient threshold, the system can automatically determine that the pressure display has abnormal display and issue an abnormal alarm. This abnormal warning and alarm mechanism can promptly remind the operator to pay attention and take corresponding measures to avoid surgical risks caused by equipment failure.

[0084] Optimize surgical procedures: By real-time monitoring and evaluation of the operating quality of the pressure display, the accuracy and stability of the electrode catheter placement during surgery can be ensured. This helps optimize surgical procedures, improve surgical efficiency, and reduce surgical risks.

[0085] Improve user experience: By improving the stability and reliability of the equipment and optimizing the surgical process, this technical solution can improve the user experience, reduce the workload of operators, and improve overall work efficiency and satisfaction.

[0086] In summary, this technical solution improves diagnostic accuracy, optimizes surgical procedures, reduces surgical risks, and improves user experience by real-time monitoring and evaluating the operating quality of the pressure display.
