Portable phono-electrocardio stethoscope and application method thereof

Abstract

The invention discloses a portable phono-electrocardio stethoscope and an application method thereof. Electrocardiogram instruments in the prior art are difficult to obtain heart sounds at the same time. According to the present invention, a shell rear cover is fixed to the top of a shell body, a stethoscope head cavity base is fixed to the shell rear cover, and a vibration film is fixed to the outer end of a cavity of the stethoscope head cavity base. A stethoscope head front cover is fixed with the stethoscope head cavity base. A sound guide tube is connected with the stethoscope head cavity base through an adapter. A microphone fixed in the sound guide tube is connected with a main control board. A first electrode plate and a second electrode plate are arranged in two placement holes in the stethoscope head front cover and below the vibrating film. The first electrode plate and the second electrode plate are both connected with the main control board. A shell base is fixed at the bottom of the shell body. A toggle switch is arranged on the shell base. The main control board is connected with a battery fixed on the inner wall of the shell body through the toggle switch. The two electrode plates are used for conducting electrocardio measurement, thereby improving flexibility. The microphone converts myocardial contraction, valve opening and closing, etc., fed back by the vibration film into electric signals, so that the phono-electrocardio combined analysis is more scientific.

Description

technical field [0001] The invention belongs to the field of medical monitoring equipment, and in particular relates to a portable heart sound ECG stethoscope and a using method thereof. Background technique [0002] In the field of medical and health care, the proportion of death caused by heart problems is very high in the total death composition, and heart-related diseases are characterized by sudden and high risk. In the evaluation of the patient's heart, it is necessary to use professional ECG measuring instruments collect the required ECG by contacting the ECG electrodes with the surface of the human body, or determine the shape and frequency composition of heart murmurs through the phonocardiogram, but these usually require professional instruments to achieve, and it is difficult to monitor the body in real time. Therefore, the portable heart sound ECG stethoscope is particularly important. [0003] At present, it is difficult for the electrocardiogram-related instru...
