Description
Technical Field
The present invention relates to the field of cardiac force analysis, and more particularly, to a system and method for dynamically monitoring cardiac force in real time.
Background
Cardiac reserve refers to the ability of cardiac output to increase with the need for body metabolism. Cardiac reserve has a strong correlation with the survival probability and the expected mortality of normal and heart disease patients. It is generally accepted that heart reserve includes heart rate reserve and myocardial contractility reserve, reflecting the ability of heart function to adapt to metabolic needs. It is affected by a number of factors, such as the increase in cardiac output when the body is subjected to intense exercise, due to the increased activity of the sympathetic adrenal system, primarily by mobilizing heart rate reserves and systolic reserves. Current research on the effect of exercise on heart rate is quite extensive. However, due to the limitations of research methods, the effect of exercise on myocardial contraction is still rarely studied. With the development and progress of scientific technology, especially the development of miniature sensors, computer multimedia technology and statistical software technology, the research becomes possible.
Currently, regarding means and methods for assessing cardiac function, electrocardiography is the best method for monitoring cardiac chronology and conductivity, but cannot be used to monitor cardiac inotropy. The examination and determination of cardiac function by cardiac catheter is objective and quantitative, but belongs to the examination with trauma; echocardiography can evaluate the functional state of cardiac muscle by measuring and calculating the degree and speed of change of the diameter of the cardiac chamber from diastole to systole and ejection fraction, but has poor sensitivity; the sensitivity and specificity of radionuclide cardiovascular pool development are high, but the examination cost is high, and the development is difficult to popularize.
The heart sounds are generated by the contraction of the heart muscle, the opening and closing of the valve, and the mechanical shock of the blood flow impacting the valve and the blood vessel wall, which are transmitted to the chest wall. If the mechanical vibration is converted into an electric signal by a transducer and recorded, a phonocardiogram is obtained. The traditional phonocardiograph has no quantitative analysis function at all, and has great limitation on the storage and processing of the heart sounds, so the clinical application is less. In recent years, due to the great challenge and attraction of heart sound signal processing, and the promising prospect of digital technology, especially multimedia technology, for solving the problems, students at home and abroad use computer technology to explore heart sound volume analysis.
The heart sound signal is a non-stationary signal, and because of the existence of various interferences, the quality of the heart sound signal acquired by the conventional method is poor, so the heart sound signal is processed before analysis, and various noises contained in the heart sound signal are eliminated. When a single heart sound signal sensor is adopted to measure heart sound signals, the heart sound signals and interference signals are simultaneously collected and entered, and the interference signals are irregular and have uncertainty, so that the interference signals are very difficult to eliminate through back-end software filtering.
When the heart force is dynamically monitored in real time, the state of a tested person is uncertain, and if the body posture of the tested person slightly changes, interference enters the sensor at any time, so that a single sensor cannot meet the requirement.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a system for dynamically monitoring a cardiac force in real time according to an embodiment of the present invention. Wherein, the heart sound signal sensor 1 is arranged in the auscultation area. Generally, there are five auscultatory regions for human heart valves: the apical area at the most forceful point of the beat, the pulmonary valve area between the second ribs on the left side of the sternum, the aortic valve area between the second ribs on the right side of the sternum, the second auscultation area of the aortic valve between the third and fourth ribs on the left side of the sternum, and the tricuspid valve area on the left side of the lower end of the sternum. The five areas completely cover the main part of the heart, and the sensors arranged in the five auscultation areas can collect and detect heart sound signals of the heart. Of course, the auscultation region can be located at other parts of the human body according to actual needs, and the invention is not described in detail.
The area outside the auscultation area is a non-auscultation area, and the sound signals in the non-auscultation area are derived from signals other than heart sounds, such as signals generated by external vibration and sound, and are referred to as interference signals in the present invention. The non-auscultation area is provided with an interference signal sensor 2 for collecting and detecting interference signals. In the present invention, the disturbing signal sensor 2 may include the first disturbing signal sensor 21, … … nth disturbing signal sensor 2 n. The data acquisition device 3 may include a heart sound data acquisition device 30, a first interference signal data acquisition device 31, an … … nth interference signal data acquisition device 3 n; wherein: the heart sound signal sensor 1 is connected with the heart sound data acquisition device 30, the first interference signal sensor 21 is connected with the first interference signal data acquisition device 31, the … … th interference signal sensor 2n is connected with the nth interference signal data acquisition device 3 n;
firstly, the heart sound signal sensor 1 and the interference signal sensor 2 respectively detect heart sound signals and interference signals in an auscultation area and a non-auscultation area, send the detected heart sound signals to the heart sound acquisition device 30, and respectively send a first interference signal and an … … nth interference signal to the first interference signal data acquisition device 31 and the … … nth interference signal acquisition device 3 n;
then, the first interference signal data acquisition devices 31, … … n interference signal acquisition device 3n respectively corresponding to the first interference signal sensor 21, … … n interference signal sensor 2n data acquisition, and transmitting the heart sound data and the interference data to the connected central processor 4;
finally, the central processing unit 4 obtains the frame of the first signal by comparing the data of the heart sound signal channel with the data of the interference signal channel, thereby judging whether the current signal is the interference signal, and calculating the frequency spectrum of the interference signal to eliminate the interference signal.
Fig. 2 is a block diagram of the internal structure of the cpu 4 of the present invention, which specifically includes: a receiving device 41, a calculating device 42, and an output device 43, which are connected in series in this order.
The reception device 41: the device is used for receiving signals output by the heart sound data acquisition device 30, the first interference signal data acquisition device 31 and the … … nth interference signal data acquisition device 3 n;
calculating means 42 for multiplying the frequency spectrum determined as the interference signal by the set suppression parameter, thereby realizing the elimination of the interference signal;
and an output device 43 for outputting the obtained interference signal-removed real heart sound signal.
Please refer to fig. 4, 5 and 6. The central processing unit 4 removes the heart sound signal (as shown in fig. 5) with the interfering signal shown in fig. 4, and obtains the whole heart sound signal (as shown in fig. 6). As can be seen from fig. 4 and 5, the heart sound signal in the auscultation area is usually accompanied by interference signals due to the unavoidable influence of external environment such as noise, posture of the examiner when the examiner is examined, and even emotion of the examiner. The heart sound signal sensor 1 is positioned in the auscultation area, and the detected signal is a heart sound signal mixed with an interference signal. Due to the non-auscultatory region, the signal received by the disturbing signal sensor 2 is only a disturbing signal.
It should be noted that, both the heart sound signal sensor 1 and the interference signal sensor 2 can adopt the heart sound sensor in the prior art to detect the heart sound signal in the auscultation area and the environmental interference signal in the non-auscultation area, respectively. Of course, the heart sound signal sensor 1 and the interference signal sensor 2 may also be other types of sensors in the prior art, and are not described herein again.
Because the interference signal is irregular and uncertain, the interference signal mixed in the heart sound signal needs to be filtered out to obtain a complete heart sound signal, so that the heart sound condition of the examiner can be truly and effectively reflected, and effective clinical guidance is provided for medical institutions.
In processing, the unit coordinates of the three signals are unified. That is, in the processing, the horizontal axis (which may be a time axis) of fig. 4 and fig. 5 should correspond to each other, so as to obtain the real heart sound data, as shown in fig. 6.
Based on the above embodiments, one or more of the display 5, the transmission device 6, the storage device 7, and the data processing device 8 may be further disposed after the central processing unit 4, and each device is connected in series with the central processing unit.
Wherein,
the display 5: the display module is used for displaying the heart sound signals after the interference signals are filtered;
the transmission device 6: all data in the analysis process can be transmitted to terminal equipment such as a computer and a mobile phone in a wireless and USB transmission mode, so that the terminal equipment can monitor heart sounds, and user experience is improved;
the storage device 7: the system is used for storing all data generated in the heart sound analysis process so as to provide data support for subsequent analysis;
the data processing device 8: the heart sound data of the examiner can be processed to obtain data reflecting other diseases such as coronary heart disease, myocarditis, etc.
It should be noted that the heart sound data acquisition device 30, the first interference signal data acquisition devices 31 and … …, and the nth interference signal data acquisition device 3n are all multi-channel acquisition devices, and can simultaneously acquire data in multiple channels and transmit the data to the central processing unit 4. In addition, the connection relationship between the above devices may be electrical connection, wire connection, signal wire connection, or other connection manners capable of realizing the functions.
The invention also discloses a heart force monitoring method for eliminating interference, which can also realize the technical effects.
Referring to fig. 3, the present invention further provides a method for dynamically monitoring the heart rate in real time, including:
s100, detecting and respectively collecting heart sound signals in an auscultation area and interference signals in a non-auscultation area;
s200, removing the interference signals in the non-auscultation area from the heart sound signals in the auscultation area to obtain real heart sound signals.
The removing of the interference signal from the heart sound signal in the auscultation region in step S200 includes:
performing signal characteristic analysis processing according to the signal frequency spectrum to obtain a frame of each signal, and judging whether the current signal is an interference signal or not according to the frame of the signal;
determining characteristic parameters such as amplitude parameters, time limit parameters and the like of the heart sound signals;
and multiplying the frequency spectrum judged as the interference signal by the set suppression parameter to eliminate the interference signal.
As can be seen from the above description of the specific embodiments, the system for dynamically monitoring the heart force in real time provided by the present invention monitors the interference signal other than the heart sound signal by arranging the interference signal sensor 2 in the non-auscultation region, and adjusts and converts the interference signal into the heart sound signal by arranging the central processing unit 4, so as to eliminate the interference signal in the heart sound signal, thereby obtaining a real heart sound signal.
It is noted that, in this specification, relational terms such as first and second, and the like are used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities.
The above provides a detailed description of the heart monitoring system and method for interference cancellation provided by the present invention. The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention.
