,Cardiac Pacemaker,faculty adviser： Liu Peng lecturer： Chen Lan,catalogue,Cardiac pacemaker constitute and principle,Cardiac pacemaker is a electronic instrument that can move into intra-individual. Through the pulse generator electrical impulses, via the conductive wire electrode conduction, stimulating electrode contact by the heart muscle，make the heart excited and contraction.,Pulse generator,pulse,currentwires and electrodes,heart muscle,local myocardial cells excite,intercellular gap junctions 、 intercalated disc connection,surrounding myocardium conduction,atrial or ventricular excite, produce contraction,Cardiac pacemaker constitute and principlele,Pacemaker system composition Pulse generator + electrode wires. Pacemaker is mainly composed of power supply (i.e. batteries, now main use lithium battery - iodine) and the electronic circuit process， can generate and output electrical pulse. Electrode conductor is the conductive wire with insulation wrapped outside, its function is to transfer the electrical impulses of the pacemaker to the heart, and the lumen electrocardiogram transmitted to the pacemaker of the heart of the sensing line,Move to artificial heart pacemaker system,Temporary cardiac pacing percutaneous pacemaker, approved by esophageal pacemaker, the chest wall puncture pacemaker, open chest epicardial pacemaker and transvenous pacemaker. Permanent pacemaker At present, most of the use of the endocardial electrode wires. Technical points including vein selection, fixed and pacemaker wire electrode embedment。,Permanent cardiac pacemaker complications,Permanent pacemaker complications Implant surgery related complications arrhythmia local bleeding cardiac perforation infection the diaphragmatic muscle stimulation,Permanent cardiac pacemaker complications,the complications related to the electrode wire and treatment measure Threshold increasing Electrode dislocation and micro dislocation Electrode wire broken or insulating layer breakdown,Permanent cardiac pacemaker complications,the complications related to the pacemaker system and treatment measure Pacemaker syndrome(PMS) Pacemaker mediated tachycardia (PMT),The safety of the pacemaker,It is safe to Install pacemaker. The overall incidence of it is only about 1%。 If it can be standardized treatment and regular follow-up, benefit is far greater than its disadvantages.,The development of the in vitro cardiac pacemaker,The development of in vitro pacemaker is in keeping with the national conditions of our country. In vitro pacemaker shape and size like a pack of cigarettes. Putting on the patients chest wall, in vitro pacemaker can produce 1 2 Gs electromagnetic field. It can be used in the bath, swimming, and physical exercise。,If there is no switch electromagnetic valve Y111 or switch is not complete, that will cause the calibration without oxygen or in pure oxygen into the air, causing calibration gas is not pure, eventually leading to oxygen monitoring is not allowed.,The reason of cardiac pacemaker replacement,clinical data: This group of 30 cases, male 18 patients, 12 cases were female; Age from 20 to 88; 26 cases replace 1 times,3 cases replace 2 times,1 case replace 3 times; Pacemaker operating life：Battery depletion 23 cases，battery depletion in advance 4 cases, infection 2cases, Wire electrode dislocation 2 cases , rejection reaction 2 cases , rejection reaction 1 cases, Pacemaker malfunction 1 cases. analysis of causes ： The depletion of the battery ； infection ； Wire electrode dislocation,Cardiac pacemaker with wireless charging system,Need Using the built-in battery as a power source， this battery always have 5 10 years of working life,Cardiac pacemaker with wireless charging system,Design,The wireless transmitter divide into three parts： oscillating circuit amplification circuit the main coil The receiving terminal divide into three parts： Rechargeable electric road rectifying circuit secondary coil,心脏起搏器用无线充电系统,心脏起搏器用无线充电系统,I hope a pacemaker popu
