The accompanying drawing explanation
?the two-in-one sonde configuration schematic diagram of Fig. 1 hear sounds electrocardio;
The two-in-one probe schematic layout pattern of Fig. 2 hear sounds electrocardio;
Fig. 3 fundamental diagram of the present invention.
The specific embodiment
As Fig. 1 is the two-in-one sonde configuration schematic diagram of hear sounds electrocardio.Electrode 102 is positioned at the below of the two-in-one probe of hear sounds electrocardio, during use, can directly contact human body.Used one deck insulant the same with electrode size above electrode, the sound transducer module is attached on insulant.Insulant and attachment of electrodes are tight, and transmitting vibrations is to sound transducer well.Module outside at electrode, insulant and sound transducer wraps up with the cylindrical shell 104 of hard, insulation and sound insulation, forms probe.105 is the sound transducer wire, and 106 is the electrocardioelectrode wire, the electrical signal conduction of sensor and electrode to signal processing system.Sound transducer has adopted the piezoelectric effect principle, is made into asymmetric, is with apertured cantilever beam structure.This size sensor is little, and precision is high.Electrode has been used common ECG electrode, as disk electrode, adsorption electrode etc.
The schematic layout pattern of two-in-one probe while as Fig. 2, being the heart comprehensive monitoring.The 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 are positioned at 203 and 205 centre, 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.Test once can obtain 7 hear sounds and the ecg information of heart like this.In common electrocardio Figure 12 leads mode, probe of the present invention relatively is adapted at using in chest lead, and other lead and remain common leading.When the heart comprehensive monitoring, use 7 two-in-one probes, can realize conventional first, second cardiophony and 6 chest leads.
