Abstract
A kind of synchronous therapeutic apparatus for coronary heart disease with electrocardio self-control function includes electrizer, its key is the electrocardiosignal of will be picked up by the electrocardioelectrode control signal as whole instrument, after ecg amplifier, A/D converter, input/output interface, computer, timing sequencer and Coupling Control Unit are handled, the output of control whole instrument pulse current, thereby constitute the therapy system of the closed loop control work asynchronously with electrocardio, characteristics such as have curative effect height, short treating period, have no side effect.
Description
The present invention relates to a kind of electrotherapeutic apparatus, especially synchronous therapeutic apparatus for coronary heart disease with electrocardio self-control function that human body is applied electric current by contact electrode.
In the prior art, the prosperous good fortune in Beijing Medical Equipment Plant produces a kind of coronary disease treating equipment, and this therapeutic instrument is directly human acupoint to be applied pulse current by electrode, all belongs to the therapy system of open loop control.The physiological characteristics of diastole and contraction is not considered in the treatment of open loop approach, and when in fact the pulse current of electrotherapy acts on the muscle contraction phenomenon that the position produced such as extremity and only occurs in diastole, just can have the electrotherapy effect that promotes vein and lymphatic return; When if the shrinkage phenomenon of limb muscle occurs in paradoxical expansion just, not only there is not the backflow effect of vein and lymph blood, peripheral blood vessel flows into large artery trunks and blood capillary swimmingly owing to limb muscle shrinks the resistance overslaugh ventricle blood that produces on the contrary, the result increases ventricular afterload, the corresponding decline of cardiac output causes myocardial damage easily, so, the electrizer of open loop situations is when treatment coronary heart disease, and its curative effect is often not good.
The purpose of this invention is to provide and a kind ofly work asynchronously the synchronous therapeutic apparatus for coronary heart disease with electrocardio self-control function of closed loop state with heart.
The object of the present invention is achieved like this: whole instrument includes electrizer, its special character is that the closed loop control signal of instrument derives from human body (electrocardio), the pulse current of instrument output acts on human body again, and obviously, the output of pulse current is controlled by electrocardiosignal.As shown in Figure 1: the human ecg signal that picks up through the electrocardio electrode is input to ecg amplifier and amplifies, electrocardiosignal after the amplification enters computer through analog-digital converter and input interface, computer carries out calculation process according to the software program of finishing in advance to input signal, export a trigger impulse synchronous in real time with electrocardiosignal, the triggering input of timing sequencer is delivered in this output through output interface, timing sequencer has three outfans, is connected with the corresponding controling end of Coupling Control Unit respectively; The output pulse current of electrizer is directly delivered to the input of Coupling Control Unit, Coupling Control Unit is assigned as the output of three ends with single-ended input, and be connected with the corresponding site of human body, thereby constitute therapy system with the synchronous close-loop control mode of human body electrocardio through therapeutic electrode.
As shown in Figure 2, whole system is made up of seven parts, i.e. electrocardio amplifier section, analog digital conversion part, input/output interface part, computer part, timing sequencer part, Coupling Control Unit part and electrizer part.Do not contain computer and electrizer because technology of the present invention solves scope, therefore, this two-part structural principle is not done narration.
