Abstract

The invention relates to the technical field of heart sound recognition equipment, and particularly relates to a multifunctional device for visual heart sound recognition. The multifunctional device is used for solving the problem that in the prior art, under the condition that the external sound is large, heart sound recognition equipment is prone to being affected and cannot normally recognize heart sounds of a patient. The multifunctional device comprises a detection box, a heart sound collector, a filter and a heart sound tube, wherein a heart sound cover is installed at the tail end of the heart sound tube; a heart sound sensor is installed at the position, close to the heart sound cover, of the heart sound tube and connected with a power source; the filter is electrically connected with an amplifier; the amplifier is electrically connected with a stethoscope and a first converter; an auscultation tube is connected to the stethoscope; an auscultation cover is installed at the tailend of the auscultation tube; and the first converter is electrically connected with a first displayer installed on the outer wall of the detection box. According to the multifunctional device, the influence of the outside on the device can be reduced by amplifying signals through the filter and the amplifier, and a doctor can more accurately recognize the heart sounds of the patient.

Description

technical field [0001] The present invention relates to the technical field of heart sound recognition equipment, in particular to a multifunctional device for visual heart sound recognition. Background technique [0002] The human heart automatically and rhythmically generates current, and the current is transmitted to various parts of the heart in the order of conducting tissues, thereby causing the contraction and relaxation of cardiomyocytes. The sound of the human heart can reflect the state of the human heart, generally using a stethoscope Directly obtain the heart sound audio signal, and judge whether the heart function is normal based on experience, but the stethoscope can only judge from the sound. In order to understand the patient's heart sound more accurately, heart sound recognition equipment is usually used. [0003] The heart sound identification equipment in the prior art comprises the electrocardiogram heart sound probe, signal processing circuit, AD convers...
