Description
Technical field
The invention belongs to a kind of defibrillation device, particularly a kind of portable endocardiac defibrillation device.
Background technology
At present, coronary heart disease is to rank first place in causing death's in the world the disease, and coronary heart disease is especially among the dead patient behind the myocardial infarction, and 2/3rds die from sudden cardiac death.Defibrillation is the unique effective therapy of treatment sudden cardiac death, and therefore, the defibrillation device is the indispensable Medical Instruments that sudden cardiac death is treated in smelting.But, the external formula cardiac defibrillator of extensive use at present, because energy is too high, even low energy shocks up to 360 joules, usually can cause serious myocardial damage to the patient, cause to occur the change of ST-T ripple on the electrocardiogram, cause myocardium label rising in the peripheral blood, continue a few hours approximately to a couple of days; Individual patient even also the myocardial infarction electrocardiogram can occur, the persistent period is also longer.In addition, electric shock, low energy shocks also can cause the serious skin burn of patient continuously.The embedded cardiac defibrillator that a kind of less use is still arranged in addition, though with high content of technology, cost an arm and a leg, and be not suitable in the first aid in hospital interim use or as the transition treatment means.
Summary of the invention
The object of the present invention is to provide a kind of price to be fit to, just to use portable endocardiac defibrillation device convenient, low-yield, the high efficiency defibrillation.
A kind of portable endocardiac defibrillation device provided by the present invention is made up of power supply, keyboard, mu balanced circuit, monitoring display circuit, mixed-signal system circuit, electrocardio amplifying circuit, high tension generator, control circuit, counnter attack charging diode, high pressure energy storage capacitor, double contact switch, electrode, wherein an end of said high tension generator is connected with power supply, the other end is connected with the mixed-signal system circuit, and the Shang Youyi end is connected with high pressure energy storage capacitor, double contact switch through the reverse charge diode.Said high tension generator is to be made of field-effect transistor and inductance, wherein the grid of said field-effect transistor is connected with the mixed-signal system circuit, its drain electrode is connected with inductance one end, and is connected its source ground with high pressure energy storage capacitor, double contact switch through the counnter attack charging diode; The other end of said inductance is connected with power supply.
When electrode enters chambers of the heart inside by human body femoral artery blood vessel, but after the perception electrocardiosignal is amplified through the electrocardio amplifying circuit, enter the mixed-signal system circuit and carry out analyzing and processing.The monitoring display circuit shows intracardiac electrocardiogram, if finding electrocardiogram occurs losing when quivering, the high tension generator that is made of field-effect transistor and inductance charges to the high pressure energy storage capacitor, after being full of electricity, control circuit starts double contact switch automatically, makes the discharge of high pressure energy storage capacitor, and output pulse width is the high-voltage pulse current that 1-6ms, voltage reach 800-1000V, generation reaches as high as 36 joules of shock energy cardiac stimulus at the electrode place, makes heart recover normal condition; Whether the heart electrocardiogram is normal after guarding display circuit demonstration defibrillation simultaneously.Said counnter attack charging diode is to prevent that the high pressure energy storage capacitor is to the high tension generator reverse charging.Said keyboard is used to import various parameters.Said mu balanced circuit is that the alternating current from power supply is carried out providing each circuit to use after the voltage stabilizing.
The present invention compared with prior art has that price is suitable, easy to use, a compact conformation, the efficient defibrillation of mental retardation, avoids causing the advantage of severe cardiac muscle injury and serious skin burn.
