Description
Technical field
The present invention relates to a kind of based on hear sounds and cardiac electrical heart overall checkout equipment.
Background technology
Analysis of PCG Signal is a kind of basic skills of assess cardiac function state.Containing a large amount of physiology about human heart and blood vessel and pathological information in cardiechema signals, and the partial information containing human body cardiopulmonary circulatory system and whole body blood circulation.The bio electricity change that electrocardiogram utilizes heart to produce in each cardiac cycle, obtains the figure of potential change by electrocardiograph.Electrocardiogram is the objective indicator of the generation of cardiac excitation, propagation and recovery process.
Current diagnostic device mostly function singleness, hear sounds can only auscultated sound, and electrocardiogram can only monitor electrocardio.For needs comprehensive diagnos hear sounds and cardiac electrical situation, needing more exchange device, will certainly be that checking efficiency is not high.Chinese patent 201020217790.6 has related to hear sounds and the comprehensive equipment of electrocardio, but the hear sounds monitoring probe of this equipment uses piezoelectric membrane, and precision is not high.Embodiment two uses mike, and mike then requires receiving chamber, and this increases the size of probe undoubtedly.Our nearest research finds, because the size of mike is comparatively large, because of fricative noise, and should not make the shortcoming of wearable device etc., and the stethoscope precision based on mike often can not meet our requirement.
Summary of the invention

Detailed description of the invention
If Fig. 1 is the two-in-one sonde configuration schematic diagram of hear sounds electrocardio.Electrode 102 is positioned at the bottom of the two-in-one probe of hear sounds electrocardio, directly can contact human body during use.Above electrode, employ the insulant that one deck is the same with electrode size, sound transducer module is pasted on the insulating material.Insulant and attachment of electrodes are tight, can well transmitting vibrations to sound transducer.Wrap up with the cylindrical shell 104 of hard, insulation and sound insulation outside the module of electrode, insulant and sound transducer, form probe.105 is sound transducer wire, and 106 is electrocardioelectrode wire, the electrical signal conduction of sensor and electrode to signal processing system.Sound transducer have employed piezoelectric effect principle, is made into asymmetric, is with apertured cantilever beam structure.This size sensor is little, and precision is high.Electrode employs common ECG electrode, as disk electrode, adsorption electrode etc.
As the schematic layout pattern of probe two-in-one when Fig. 2 is heart comprehensive monitoring.Probe position respectively: 201 are positioned at right border of sternum the 4th intercostal, 202 are positioned between the second rib of breastbone left and right edge, 203 are positioned at left border of sternum the 4th intercostal, 205 are positioned at left mid-clavicular line and the 5th intercostal place, 204 centres being positioned at 203 and 205,206 are positioned at left anterior axillary line and 205 same level places, and 207 are positioned at midaxillary line and 205 same level places.Probe 201,203,204,205,206,207 can complete 6 kinds of conventional chest leads, and 202 and 205 monitorings that can complete first heart sound and second heart sound of popping one's head in.Such test once can obtain 7 hear sounds and the ecg information of heart.Lead in mode at common electrocardio Figure 12, probe of the present invention compares and is adapted at using in chest lead, and other lead, and remain common leading.When heart comprehensive monitoring, use 7 two-in-one probes, first, second conventional cardiophony and 6 chest leads can be realized.
