Wearable cardiac sound monitoring device

Abstract

The invention discloses a wearable cardiac sound monitoring device. The wearable cardiac sound monitoring device comprises a wearable cardiac sound acquiring and sensing module, a mobile phone cardiac sound signal receiving and processing information module and a central server, wherein the wearable cardiac sound acquiring and sensing module consists of a microphone, a signal amplifying and transmitting circuit, a microprocessor, a wireless transmission module, an earphone shell and a wearable fixing device; a cardiac sound signal of a user is collected through the wearable cardiac sound acquiring and sensing module, and passes through the signal amplifying and transmitting circuit, namely, a circuit amplifying circuit and an A/D (Analog to Digital) sampling circuit to obtain a cardiac sound electronic signal; the cardiac sound electronic signal is transmitted to mobile phone equipment through wireless transmission equipment; the corresponding cardiac sound signal receiving and processing information module is arranged on a mobile phone; the received cardiac sound electronic signal is subjected to digital filtration and computation to obtain corresponding cardiac sound information; the acquired cardiac sound information is transmitted to the central server through the mobile phone. An algorithm is implemented through an algorithm, an entropy relation between a fuzzy signal and a signal is used for predicting the future health state of heart through computation, and the user is promoted of matters needing attention in advance.

Description

technical field [0001] The invention is a wearable heart sound monitoring device, which belongs to the technical field of medical instruments. Background technique [0002] There are already inspection methods for maternal and fetal ECG information, but there are not many detection methods for heart sound signals. Although this is one of the most important acoustic signals of the human body, it is the most basic method for clinical evaluation of cardiac function status, and it is the mechanical movement state of the heart and great vessels. Before the cardiovascular disease has developed enough to produce clinical and pathological changes (such as ECG abnormalities), the murmurs and distortions in heart sounds are important diagnostic information. However, the utilization and development of heart sound analysis are hindered for the following reasons.

Problems solved by technology

[0008] The existing products on the market are basically products with a single function, that is, there is no product that integrates the three functions of dynamic ECG, abnormal event monitoring and ECG telemetry

Although the ECG remote monitoring technology has made great progress, it is still necessary to develop some intelligent judgment functions; and the remote monitoring and diagnosis system of the human ECG in the prior art cannot fully satisfy some special users including common diseases of the elderly, such as Patients with heart and brain diseases need remote recording, monitoring and diagnosis systems and related methods of physiological information (extended human health information) other than ECG information

[0009] At present, there is a lack of quantitative heart sound analysis technology; auscultation is easily affected by the subjective judgment of doctors, and doctors often cannot clearly distinguish a large number of ground heart sound components with diagnostic significance. Often only experienced cardiologists can evaluate the function of the heart through auscultation status, making proper evaluation and diagnosis

[0010] Conventional heart sound auscultation cannot continuously monitor the user's heart sound information, and a large amount of diagnostic information will be lost, reducing the accuracy of heart sound diagnosis

[0011] Users lack auscultation knowledge and cannot self-diagnose. They must rely on experienced doctors to make a diagnosis, which limits the user's use space

Due to the above reasons, the development of heart sound diagnosis has been greatly restricted.
