technical field

The invention belongs to the technical field of medical monitoring, and in particular relates to a cardiac pacing monitoring system based on piezoelectric energy capture.

Background technique

At present, there are various types of physical indicators in the monitoring of the patient's physical condition, and the most intuitive one is the heartbeat. If manual collection and recording are required, it will consume a lot of manpower, material resources, and time, and there are a large number of patients in large hospitals. It is also difficult to collect and process the heartbeat status of each patient synchronously in practice. There are many problems in practical applications and it is not operable. In addition, due to the artificial recording of data, different types of data records will be out of sync and the artificial recording process may be Various errors and other factors lead to unreliable data.

In order to solve the above-mentioned technical problems, the present invention is realized through the following technical solutions: the present invention provides a cardiac pacing monitoring system based on piezoelectric capture energy, comprising:

Piezoelectric device, installed in the patient's body, and the beating of the heart excites the piezoelectric device to generate an electrical signal;

a data processor, connected to the piezoelectric device, for comparing the electrical signal generated by the piezoelectric device with the value range of the electrical signal generated by a normal heartbeat, and sending a feedback signal if the electrical signal is abnormal;

The hospital control center, connected with the data processor, is used for receiving the feedback signal, and performing rescue work on the patient through the feedback result.

From the above, the entire monitoring process does not require human intervention, which effectively avoids the influence of human errors and other factors on the results, reduces the workload of human beings, and greatly improves the efficiency of work, with fast speed, low cost, low labor intensity, and reliability. It has high performance and solves many problems such as insufficient manpower, high labor intensity and poor reliability when manually monitoring the patient's physical state.

Optionally, the abnormality of the electrical signal includes:

The electrical signal is greater than the upper limit of the electrical signal value range generated by normal heartbeat, and the feedback signal is a "tachycardia" signal;

When the electrical signal is less than the lower limit of the range of electrical signal values produced by a normal heartbeat, the feedback signal is a "bradycardia" signal.

Further, it also includes a heartbeat pacemaker, installed in the patient's body and connected to the data processor, when the electrical signal is less than the lower limit of the electrical signal value range generated by a normal heartbeat, the data processor excites the heartbeat pacemaker Work.

Optionally, it also includes a display, which is arranged in the hospital control center and used to display the comparison result of the data processor.

Optionally, it also includes a first alarm device and a second alarm device. When the electrical signal exceeds the upper limit range of the electrical signal value generated by the normal heartbeat, the second alarm device sends an alarm of tachycardia to the hospital control center. ; If the electrical signal is less than the lower limit of the reasonable range of the electrical signal value generated by the normal heartbeat, the first alarm device sends a bradycardia alarm to the hospital control center while the heartbeat pacemaker is working.

From the above, the cardiac pacing monitoring system based on piezoelectric capture energy of the present invention monitors the heartbeat of hospitalized patients, and can monitor the physical conditions of multiple patients simultaneously and synchronously by installing piezoelectric devices on the patient, which overcomes the original monitoring. The method has the disadvantages of large workload, human error, and inability to synchronize acquisition in real time. Due to the large number of patients in large hospitals, manual collection, comparison and monitoring consume a long time, and the final result may be affected by the operation error of the staff, and the speed and reliability of the information cannot be guaranteed. The cardiac pacing monitoring system can collect the heartbeat status of the human body by means of system and computer program control, which effectively solves the problems of poor synchronization, human error, low reliability, and insufficient medical personnel in manual monitoring. Due to the inherent problems of long period and high labor cost, the piezoelectric capture energy-based cardiac pacing monitoring system of the present invention has short period, high precision, low cost, high efficiency and reliability, and does not require a large amount of manual participation, and will not factors affect the monitoring results.

Detailed ways

The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. As a part of the present specification, the principles of the present invention will be illustrated by examples. Other aspects, features and advantages of the present invention will become apparent from the detailed description. In the figures to which reference is made, the same reference numerals are used for the same or similar parts in different figures.

As shown in Figures 1-3, the cardiac pacing monitoring system based on piezoelectric captured energy provided by the present invention collects the heartbeat state of hospitalized patients, including a piezoelectric device 1 installed in the patient's body, and the beating of the heart excites the piezoelectric device 1 The electrical signal 6 is generated, the piezoelectric device 1 feeds back the electrical signal 6 to the computer 2, and the data processor 7 in the computer 2 can transmit the electrical signal 6 from the piezoelectric device 1 to the computer 2 and the electrical signal generated by a normal heartbeat The value ranges are compared, and the monitoring results are finally fed back to the hospital control center 3. The pacemaker 8 is also in the patient’s body. When the data processor 7 determines the “bradycardia” signal 5 through logic, the pacemaker 8 is stimulated to work. , at the same time, the data processor 7 will feed back the results to the hospital control center 3, and the medical staff will quickly go to the hospital for treatment. In addition, when the electrical signal 6 generated by the piezoelectric device 1 is greater than the upper limit of the reasonable electrical signal range generated by a normal heartbeat, the data processor 7 will output a "tachycardia" signal 4 to the hospital control center 3. When the signal is received The hospital will quickly dispatch medical staff to the treatment. The piezoelectric device 1 of the present invention monitors the heartbeat, and the data processor 7 in the computer 2 can not only stimulate the heartbeat pacemaker 8 to work, but also can feed back the judgment result to the hospital control center 3. In the case of delay, when the medical staff did not arrive, it played a certain temporary rescue role.

The invention utilizes the piezoelectric effect, that is, when some dielectrics are deformed by external force in a certain direction, polarization phenomenon will be generated inside, and positive and negative opposite charges will appear on its two opposite surfaces at the same time. Vibration is also a transmission method of force, and the heartbeat of the human body is also a kind of vibration. Therefore, a piezoelectric device 1 is installed inside the human body, and the piezoelectric device 1 will generate electrical signals when subjected to vibration, and different vibrations The electrical signal is also different. The heartbeat of the human body provides a vibration for the piezoelectric device 1. After the vibration generates an electrical signal, the electrical signal is sent to the computer 2. The data processor 7 of the computer 2 feeds back the comparison result to the hospital through logical judgment. On the display screen of the control center 3, medical staff treat patients through feedback results, which realizes the synchronization of patient status monitoring, reduces the labor intensity and difficulty of medical staff, and improves monitoring efficiency and reliability.

The alarm process of the present invention is shown in FIG. 3 , the electrical signal 6 generated by the piezoelectric device 1 first enters the data processor 7, and the data processor 7 makes a judgment. If the electrical signal 6 is within the normal range, the switches S1 and S2 are both Disconnect, if the electrical signal 6 exceeds the upper limit range of the electrical signal value generated by the normal heartbeat, then close the switch S2, the second alarm 10 sends an alarm of tachycardia to the hospital control center 3, and the medical personnel go to the rescue; if When the electrical signal 6 generated by the piezoelectric device 1 is less than the lower limit of the reasonable range of the electrical signal value generated by the normal heartbeat, the switch S1 is closed, and the heartbeat pacemaker 8 is working at the same time, the first alarm 9 sends out a heart beat to the hospital control center 3. Slow alarm, medical staff went to treat.

The piezoelectric capture energy-based cardiac pacing monitoring system of the present invention has a relatively low degree of manual participation, relatively accurate data collection, reduces labor costs, avoids errors as much as possible, saves time, and solves possible human errors in human monitoring and insufficient number of medical staff. It can avoid problems such as low accuracy of collected data, excessive error, and untimely monitoring and treatment.

The using method of the cardiac pacing monitoring system based on piezoelectric capture energy of the present invention is as follows:

As shown in FIG. 1, the electrical signal 6 generated by the piezoelectric device 1 installed in the patient is first monitored, and the electrical signal 6 is transmitted to the computer 2. The data processor 7 in the computer 2 makes a logical judgment. If When bradycardia occurs, the data processor 7 starts the pacemaker 8 quickly, and sends a "bradycardia" signal to the hospital control center 3; if tachycardia occurs, the data processor 7 will quickly report to the hospital control center. 3 Feedback "tachycardia" signal, this method solves the problem of insufficient medical staff in large hospitals. When the monitoring work is difficult and huge, this method can reduce labor intensity and improve reliability. In the process of monitoring, the degree of manual participation is low, which reduces the workload of medical staff. The accuracy of judging the patient's heartbeat by the program system is relatively high, which effectively avoids many problems caused by human reasons, and improves the physical condition of hospital patients. Monitoring opens up a new way of thinking.

The piezoelectric device 1 and the cardiac pacemaker 8 of the present invention are both placed inside the patient's body. The logic judgment system of the data processor 7 pre-stores various state parameters under the condition of normal human heartbeat. The piezoelectric device 1 is placed in the patient's body. The electrical signal 6 is generated due to the beating of the heart, and the electrical signal is input into the computer 2. The data processor 7 inside the computer compares the input electrical signal with the electrical signal range of the normal heartbeat in the system. If the electrical signal 6 is within Within the normal range, the piezoelectric device 1 continues to collect electrical signals. If the electrical signal sent by the piezoelectric device 1 to the data processor 7 is greater than the upper limit of the reasonable electrical signal range of the electrical signal value generated by the normal heartbeat, the data processor 7 will send the data to the data processor 7. The hospital control center 3 gives feedback and sends out a "tachycardia" signal 4, and the medical staff comes for treatment; if the electrical signal 6 generated by the piezoelectric device 1 is lower than the lower limit of the reasonable range of the electrical signal value generated by the normal heartbeat, the data processor 7. Quickly stimulate the pacemaker 8 to work, and at the same time send a "bradycardia" signal 5 to the hospital control center 3, and medical personnel come to treat.

The cardiac pacing monitoring system based on piezoelectric capture energy of the present invention is mainly used in large hospitals to monitor the heartbeat of patients, which reduces the workload of manual operation, improves the efficiency and reliability of monitoring work, and alleviates the shortage of medical personnel. The problem. The invention uses the program to compare the electrical signals to monitor the state of the human body. The piezoelectric device and the heartbeat pacemaker are both placed in the human body. The piezoelectric device stimulates the electrical signal through the beating of the human heart and feeds the electrical signal back to the computer. At the same time, the data processor in the computer processes and judges the input electrical signal. If the electrical signal is abnormal, the system will send out different feedback signals according to the difference. The present invention uses the program control method to judge the electrical signal. The monitoring process does not require human participation in the whole process, and the piezoelectric device will also produce obvious electrical signal changes when there is a slight change in the heartbeat, that is, it has sufficient sensitivity, the computer can remotely control the pacemaker, and the hospital controls the operation. The center has the ability to receive the final feedback information from the system.

The above descriptions are only the preferred embodiments of the present invention, of course, it cannot limit the scope of rights of the present invention. It should be pointed out that for those skilled in the art, without departing from the principles of the present invention, Several improvements and changes are made, and these improvements and changes are also regarded as the protection scope of the present invention.
