Description

Technical Field

[0001] The present invention relates to the technical field of health monitoring, and in particular to a real-time monitoring system for chronic left heart failure disease states, a computer-readable storage medium and an electronic device. Background Art

[0002] Chronic heart failure is the terminal stage of the development of various heart diseases, characterized by high morbidity, high mortality, high re-hospitalization rate and low quality of life. With the development of the global aging trend, the incidence and prevalence of heart failure have increased year by year, bringing a heavy burden to the social economy and becoming a major disease that seriously threatens life and health.

[0003] Chronic left heart failure refers to heart failure caused by chronic compensatory dysfunction of the left ventricle. It is extremely common clinically and is characterized by pulmonary circulation congestion. The typical manifestations of most patients with left heart failure include: 1) Dyspnea on exertion, dyspnea due to decreased exercise tolerance, that is, patients become breathless or even have difficulty breathing after a little exercise. 2) Orthopnea, a state in which dyspnea occurs when lying flat and the patient must take a high pillow, semi-reclining or sitting position to relieve or alleviate dyspnea. Mild cases can be improved by using a high pillow or semi-reclining position, but severe cases must be relieved by sitting upright; 3) Paroxysmal nocturnal dyspnea, which typically occurs after 1 to 2 hours of deep sleep at night. The patient is awakened by shortness of breath and is forced to sit up, which can be relieved.

[0004] In the existing technology, it is very difficult to accurately monitor the symptoms of left heart failure in the early stage, especially when the symptoms are mild, they are easily ignored by patients. When patients have obvious symptoms of dyspnea during exercise or rest and go to the doctor, it often means that left heart failure has developed to a more serious degree, and the best time for early intervention and early treatment has been missed.

BRIEF DESCRIPTION OF THE DRAWINGS

[0062] Other features, objects and advantages of the present invention will become more apparent from the detailed description of non-limiting embodiments made with reference to the following drawings:

[0063] Figure 1 It is a schematic diagram of the process steps of the present invention. DETAILED DESCRIPTION

[0064] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0065] A real-time monitoring system for chronic left heart failure disease state provided by the present invention comprises:

[0066] Module M1: receiving collected signals from the attitude sensor and the sound sensor; the sound sensor includes a respiratory sound sensor and / or a lung sound sensor, specifically, collecting signals through a combination of the attitude sensor and the respiratory sound sensor, or through a combination of the attitude sensor and the lung sound sensor, or through a combination of the attitude sensor, the lung sound sensor and the respiratory sound sensor; the attitude sensor can use an IMU attitude sensor to collect acceleration signals of the wearer's chest, and in a preferred example, it is attached to the lower part of the sternum to collect six-axis acceleration signals to detect the six-axis acceleration information of the patient's torso, a lung sound sensor is attached to the lower part of one side of the wearer's chest wall, or two lung sound sensors are respectively attached to the lower part of the left and right chest walls of the wearer; in a preferred example, the lung sound sensor collects lung sound signals at the bottom of the lungs on both sides;

[0067] Module M2: obtains the posture information of the wearer's torso according to the collected signal of the posture sensor, and obtains the wearer's sound information, such as the lung sound information at the bottom of the lung and the breathing sound information of the neck, according to the collected signal of the sound sensor;

[0068] Module M3: Prompt early warning of chronic left heart failure based on the posture information and sound information. Specifically, the early warning of chronic left heart failure is provided based on the posture information and the lung sound information and / or the breathing sound information.

[0069] The posture sensor collects the six-axis acceleration signal at the lower part of the wearer's sternum, the two lung sound sensors collect the lung sound signals at the bottom of the wearer's lungs on both sides, and the breath sound sensor collects the breath sound signal at the wearer's neck. The monitored person only needs to wear at least one posture sensor and one sound sensor (referring to the sound sensor used as a lung sound sensor); or at least one posture sensor and one sound sensor (referring to the sound sensor used as a breath sound sensor). Wearing lung sound sensors on both lungs at the same time is more conducive to providing comprehensive characteristics of bilateral lung sound changes and increasing the sensitivity and specificity of judgment. Breath sound sensors worn on the neck or the upper part of the sternum are conducive to providing more abundant information on changes in respiratory characteristics, and can also increase the sensitivity and specificity of judgment. In a variation, some breath sound characteristics can also be calculated from the lung sound sensor, so that one breath sound sensor can be worn less.

[0070] The posture information includes: the wearer is in a sitting position, the wearer is in a lying position, and the wearer is in motion; wherein the wearer's motion state includes motion of different amounts of motion; the lung sound information includes: normal lung sounds, coarsening lung sounds, lung sounds with different degrees of rales, and rales of different natures, such as dry rales and wet rales; the respiratory sound information includes: respiratory rate, respiratory amplitude, duration of inspiratory phase, duration of expiratory phase, and accompanied by signs of dyspnea.

[0071] The module M3 comprises:

[0072] Module M301: obtaining the posture change of the wearer according to the posture information, and obtaining the change relationship of the amount of exercise according to the posture change;

[0073] Module M302: obtaining a posture change of the wearer according to the posture information, and obtaining a change relationship of the lung sounds and / or breathing sounds before and after the posture change of the wearer according to the sound information;

[0074] Module M303: Based on any one or more of the relationship between the posture change and the amount of exercise, combined with any one or more of the relationship between the change in breathing sounds and the change in lung sounds, a warning prompt for chronic left heart failure is issued.

[0075] In the module M303, lung sounds are taken as an example among lung sounds and breath sounds:

[0076] When the wearer changes from a sitting position to a lying position, calculate the changes in lung sounds, including whether the lung sounds become coarser, whether there are rales of different degrees, whether there are changes in respiratory frequency and amplitude, whether there is dyspnea, and calculate how long the lung sound changes occur in the lying position; and when the lung sound changes occur, the wearer changes from a lying position to a sitting position, and the lung sound changes are alleviated; then a warning is issued; that is, a warning is issued according to the relationship between posture changes and lung sound changes;

[0077] When the wearer is in motion, if the lung sounds become coarser, or different degrees of rales are detected, if there are changes in breathing frequency and amplitude, or if there are signs of dyspnea, the wearer's exercise intensity and duration are calculated; if the changes in lung sounds do not match the intensity and duration of exercise, a warning is issued; that is, a warning is issued based on the relationship between the change in exercise volume and the change in lung sounds;

[0078] Taking breathing sounds as an example, when the wearer is in a sitting position for more than a first period of time and then walks or runs continuously for a second period of time, when the wearer's speed is lower than the speed threshold or the wearer's continuous exercise time is less than the time threshold, if the breathing sound information shows that the increase in breathing rate is greater than the amplitude threshold, the breathing sounds become coarser, or rales of varying degrees appear, a warning will be issued.

[0079] The posture sensor and sound sensor (lung sound sensor and breathing sound sensor are both sound sensors) of the present invention perform time-synchronized signal acquisition, so that early warning prompts can be obtained through rules. For example, when the patient is in a supine state, the changes in lung sounds are calculated: whether the lung sounds become coarser, whether rales appear, and whether dyspnea occurs; how long does it take for the lung sounds to change while lying flat; after the above-mentioned lung sound changes occur, the patient sits up, and whether the above-mentioned lung sound changes are alleviated, which is a combination of posture and lung sounds at synchronized time. For another example, when the patient is in a non-supine state, when it is calculated that the lung sounds become coarser, or rales of different degrees and natures appear, or dyspnea characteristics appear, the following are calculated: the patient's current state, whether he is in motion, and the intensity and duration of the exercise, which is a combination of posture, lung sounds, and breathing characteristics.
