Abstract
The invention discloses a portable simple heart first-aid device, which consists of microprocessor and electric pulse signal generating circuit, wherein the pacing electrode connects the pulse output end of electric pulse signal generating circuit, which is set on the pacing conduit in the body esophagus; the electrode proceeds pulse stimulation the heart directly, which needs little electric current; the frequency and strength of electric pulse signal can be adjusted real-time, which makes the electric pulse at the most fitful parameter.
Description
Technical field the present invention relates to a kind of heart emergency treatment instrument of medical instruments field.
Background technology heart disease is called " first killer " in various human diseasess, its sickness rate occupies first of various serious diseases, disease of ZANG-organs accounts for 23% at various diseases cause of death center, this is relevant with heart attack, characteristics critical, that the sudden death rate is high, in rescue patient life, no matter take what heart disease emergency treatment, it in time all is most important rescuing.
And because cardiopathic sudden, generally can't predict its disease time, if when morbidity at home or in outdoor activity, often can't in time be delivered to hospital and rescue, can only carry out simple measures such as some artificial cardiac massages, effect is undesirable, cause patient's life danger, so, when the heart disease patient shows effect, a kind of effective emergency cardiac care instrument preferably can be arranged at one's side, rescue the most timely and effectively obtaining.
Existing heart disease first-aid apparatus, comprise portable cardiac pacing instrument or be equipped on the chest electric shock equipment of hospital, it all is the mode that adopts by the body surface electric shock, need stronger shock current, and owing to the peptizaiton of body surface to electric current, practical function is not easy control to the electric current of heart, and the pace-making effect is bad.And volume is bigger, and price is also high, generally is equipped on hospital, is difficult to enter average family.The portable heart emergency instrument that a kind of simple and practical entered family of market demand uses.
Summary of the invention the object of the invention is to disclose a kind of heart emergency treatment instrument that adopts electric shock working method in the body.
The object of the present invention is achieved like this, it comprises microprocessor MCU, pulse signal generation circuit, display circuit and control circuit etc., it is characterized in that: described heart emergency treatment instrument also has a pacing catheter that can insert the human body esophagus, pacing electrode is installed on the pacing catheter, and pacing electrode is connected on the pulse output end of pulse signal generation circuit.
Described heart emergency treatment instrument also has feedback control circuit, it is characterized in that: the exploring electrode that is used to survey electrocardiosignal in the esophagus is installed on the pacing catheter, after the output of exploring electrode is changed by the A/D change-over circuit, be connected to microprocessor MCU, microprocessor MCU is through calculation process, sends to pulse signal generation circuit to be used for adjusting in real time the frequency of control electric shock pulse signal and the control instruction of intensity.
" domestic portable simple heart emergency treatment instrument " of the present invention, shock by electricity the outward mode of pace-making of employing body surface different from the past, and adopt a kind of brand-new emergency cardiac care working method, it sets up a kind of passage through esophagus pace-making heart, stops dancing hour of danger at patient's heart, and the pace-making conduit is inserted esophagus, open this emergency instrument, produce suitable electric stimulation pulse, send to stimulation location by pacing electrode, cardiac stimulus is pace-making again.Owing to be to carry out impulse stimulation by the electrode pair heart that inserts esophagus, there is not the peptizaiton of body surface, more direct to the stimulation of heart, pace-making is more effective, and the shock current that needs is less, can make portable, carry and use more conveniently, be fit to enter family and use.
Feedback control circuit of the present invention, survey intraesophageal electrocardiosignal by exploring electrode, by A/D conversion and microprocessor calculation process, send control instruction to pulse signal generation circuit, adjust the frequency and the intensity of control electric shock pulse signal in real time, make the electric shock pulse of cardiac stimulus be adjusted at only parameter, obtain best pace-making effect.When detecting patient's heart again during pace-making, the output of the pulse that stops automatically shocking by electricity.
Appended drawings is the operation principle block diagram of the embodiment of the invention.
With reference to the accompanying drawings embodiments of the invention are described below the specific embodiment.
Existing heart disease first-aid apparatus, comprising portable heart pace-making instrument and the chest electric shock equipment that is equipped on hospital, all is the mode that adopts by the body surface electric shock, because body surface is to the peptizaiton of electric current, practical function is not easy control to the electric current of heart, and the pace-making effect is bad.And volume is bigger, and price is also high, generally is equipped on hospital, is difficult to enter average family.
The present invention adopts the basic fundamental of existing heart emergency treatment instrument, mainly comprise existing microprocessor MCU part, produce the pulse signal generation circuit of electric shock pulse, parts such as display circuit and control circuit, the technology of this respect belongs to the technology of existing product, does not do explanation here.
Creativeness of the present invention, be not adopt the working method of tradition by the body surface electric shock, but set up the passage that carries out cardiac stimulation by esophagus, electric shock signal with pulse signal generation circuit output, be connected on the pacing electrode, and pacing electrode is installed on the pacing catheter of the use nontoxic biological material manufacture that can insert esophagus, stop dancing hour of danger at patient's heart, the pace-making conduit is inserted esophagus, open this emergency instrument, produce suitable electric stimulation pulse, send to stimulation location by pacing electrode, cardiac stimulus is pace-making again.Owing to be to carry out impulse stimulation by the electrode pair heart that inserts esophagus, pacing electrode is in the body and very near heart, does not have the peptizaiton of body surface, stimulation to heart is more direct, pace-making is more effective, and the pace-making voltage low (15-45V) that needs, and electric current is little, overall power consumption is little, both can use family's AC network power supply, and also can use battery to provide stabilized power source to system, so that be fit to outdoor application by the DC-DC mapping mode, be convenient to make portable, carry and use more convenient.
Heart emergency treatment instrument of the present invention also has feedback control function, its circuit structure is: the exploring electrode that is used to survey electrocardiosignal in the esophagus is installed on pacing catheter, after the output of exploring electrode is converted to digital signal by the A/D change-over circuit, be connected to microprocessor MCU, microprocessor is through calculation process, send control instruction to pulse signal generation circuit, adjust the frequency and the intensity of control electric shock pulse signal in real time, make the electric shock pulse of cardiac stimulus be adjusted at only parameter, obtain best pace-making effect.When detecting patient's heart again during pace-making, stop automatically the shocking by electricity output of pulse of control wave generation circuit.
Exploring electrode can be and pacing electrode electrode independently in addition, also can directly use pacing electrode as exploring electrode, i.e. two shared one group of electrodes of function, at this moment must be by the work of staggering in time of microprocessor MCU control detecting function and pacing function, promptly when electrode is in the pace-making state, close the input of detecting function circuit, when electrode is in the output time gap of pace-making state, just open the input of detecting function circuit, avoid both work conflict.
