Problems solved by technology

At present, the price and function of domestic and foreign electronic stethoscope products are quite different. The performance of foreign electronic stethoscope products is better but the price is high. Compared with foreign products, there is still a big gap in the performance of domestic products. Most of them just collect heart sounds and amplify them. Although the stethoscope has been improved to a certain extent,

Embodiment

[0059] see figure 1 Shown, it is shown as the schematic diagram of the electronic auscultation system of the present invention. As can be seen from the figure, the electronic auscultation system mainly includes three parts: a stethoscope head 101 , a sound pickup part 102 , and a data recording and processing part 103 . Wherein, described stethoscope head 101 is the sound acquisition of stethoscope and conduction part; Described sound pick-up part 102 converts the sound transmitted by stethoscope head into electrical signal; A terminal device for recording and processing sound data by a method for processing and graphic display of heart sounds, the terminal device includes a mobile phone, a tablet computer and a computer; the auscultation head 101 is connected to the sound pickup part 102; the sound pickup part 102 is connected to the data recording and processing part 103 can be connected by wire and / or wirelessly.

Abstract

The invention discloses a method for cardiac sound waveform data processing and graph displaying and an auscultation system. With a cardiac sound waveform data processing method, characteristics of a first cardiac sound and a second cardiac sound can be identified accurately and automatically without the need to input any parameter by a user and a heart rate is extracted in real time. With a cardiac sound graph displaying method, an original cardiac sound graph and a similar electrocardiogram after data processing are displayed on a same graph simultaneously; and up-down comparison of characteristic points is realized conveniently by sharing a same timer shaft. Therefore, the original fluctuation situation of the original cardiac sound graph can be observed and the cardiac sound characteristics can be observed clearly in the similar electrocardiogram after data processing, so that a visualized effect of the cardiac sound graph is realized and a clear cardiac sound graph can be obtained and thus the diagnosis becomes accurate. With an electronic auscultation system, a heart rate can be record and extracted in real time and a clear cardiac sound graph can be displayed.

Description

technical field [0001] The invention relates to a heart sound data processing and display technology of an electronic stethoscope, in particular to a heart sound waveform data processing and graphic display method and an auscultation system thereof. Background technique [0002] In clinical work, medical staff often have to rely on a stethoscope to obtain the sound of human internal organ activities outside the body through the stethoscope, so that the medical staff can initially determine the cause of the disease. [0003] Heart sound is a sound that can reflect the normal or pathological state of the heart. It is formed by the opening and closing of each valve and the vibration generated by the movement of the myocardium and blood during the heartbeat process. Auscultation of heart sounds is an important basis for diagnosing heart disease. The traditional method is to use a stethoscope to auscultate heart sounds, and the basis for diagnosis is mainly the experience of doc...
