Abstract
The present invention is a kind of computer-shape fully-automatic extracorporeal reverse beating device that grows up on former manual external counterpulsation apparatus basis, be characterized in adopting non-invasive pressure pulse wave signal to carry out closed loop feedback control, the diastolic wave starting point of temporo arterial pressure pulse wave is in the incisura place when guaranteeing counter fighting, to obtain desirable curative effect.On fluorescent screen, show electrocardiogram simultaneously, fill aerofluxus, pressure pulse wave and blood flow waveform and heart rate, premature beat counting, before counter the fighting and during counter fighting pressure pulse wave relaxing period and Syst area than and the relative blood flow value.
Description
The fully-automatic extracorporeal reverse beating device that uses universal microcomputer is a kind of Medical Instruments of the multiple ischemic diseases of treatment, belongs to medical Instrument field.
Diseases such as present treatment people's multiple ischemic diseases such as coronary heart disease, cerebral arteriosclerosis, embolism of central retinal artery, the domestic external counterpulsation method that all adopts is impelled the disease location normal circulation of blood flow at human body, reaches therapeutic purposes.External great majority adopt aorta inner bag counterpulsation (traumatic) treatment ischemic diseases.It is domestic that the patent No. is arranged is 85200905 analogous instrument, but these instruments all belong to manual type, promptly detect the QRS ripple, trigger the inflation aerofluxus of air valve with the R ripple, the time of inflation is to cooperate manual adjustment again according to the ear-lobe pulse wave, because the ear-lobe pulse wave does not have tangible incisura (being the separation of systole and relaxing period), rely on the method for manually adjusting external counterpulsation, can not obtain good curative effect, and owing to can not determine best external counterpulsation inflation zero-time, to influence the Syst blood of normally penetrating, human body will be had certain potential danger.
The objective of the invention is to design a kind of full-automatic no wound external counterpulsation control system of using universal microcomputer, it detects the timing of temporo tremulous pulse (perhaps radial artery, common carotid artery) pulse wave signal as the air valve inflation, utilize microcomputer to realize feedback control again, to obtain the best external counterpulsation time, reach best therapeutic effect.
Advantage of the present invention is: inflationtime, evacuation time and inlet and outlet pressure are realized Automatic Control, and guarantee that inflationtime is accurate.Four lines of realizing electrocardiosignal, switch valve signal, temporo arterial pressure pulse wave signal, temporo blood flow volume signal on 8088 microcomputers show.Also can carry out heart rate counting, premature beat counting, the anti-counting of fighting, the ratio of counter fight temporo auterial diastole phase and systole area during preceding and counter fighting, the numerical value of temporo tremulous pulse relative blood flow value shows and the inverse of the anti-time of fighting shows, the sick icon demonstration of planting (limbs, heart, eye) of treatment before counter the fighting and during counter fighting, eventually last admission pressure shows (0.3,0.4,0.5,0.6kg/cm
2), control device has memory function and freezes visual function.
Describe operation principle of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the anti-control system block diagram of fighting, from electrocardiosignal, detect the R ripple among the figure, one the tunnel send the heart rate sample circuit, so that the signal of each cardiac cycle of real-time sampling, one the tunnel as the heart rate sample interrupt request singal, after handling, interrupt service routine calculates a preliminary inflation aerofluxus timing signal, this signal is delivered to output driving circuit through driving the valve timing circuit and closing the valve timing circuit, start the inflation and the aerofluxus of charging valve then, the A/D change-over circuit is sampled respectively before counter the fighting, the time temporo arterial pressure pulse wave signal, changing value and the anti-numerical value of fighting preceding point of contact A of temporo tremulous pulse point of contact B constantly compare during counter the fighting of 8088 micro computers foundation, generate a controlled quentity controlled variable of constantly adjusting inflationtime, reach feedback closed loop control, before the A/D translation circuit is also gathered counter fighting, the time blood flow variation numerical value, carry out numerical value by the CRT of microcomputer and show, so that the curative effect when determining counter fighting quantitatively.A/D sample generator circuit is used for guaranteeing that micro computer CRT shows, and can constantly refresh or freeze image.Markers generation circuit produces the complete machine timing of standard, provides screen numerical value to show clear screen when not concluding.The I/O decoding circuit is used for guaranteeing foregoing circuit and 8088 micro computer CPU co-ordinations.
Fig. 2 is temporo arterial pressure pulse wave, ear-lobe pulse wave and electrocardiogram, phase relation when phonocardiographic.As seen from the figure, the A boundary line, point of contact of temporo arterial pressure pulse wave is very obvious, and the ear-lobe pulse wave does not have obvious point of contact.Temporo arterial pressure pulse wave point of contact A stops back (the expression relaxing period begins) at ECG T wave and is positioned at second heart sound S
2(be aorta do close sound) located, because common carotid artery, temporo tremulous pulse, the centrifugal dirty distance of radial artery do not wait, so the pulse wave incisura is slightly variant in time.
Fig. 3 is before the external counterpulsation and the situation of change of ear-lobe pulse wave and temporo arterial pulse wave during counter fighting, as seen from the figure, counter fighting four minutes whens beginning, the diastolic wave starting point B of temporo arterial pressure pulse wave, overlapping with the anti-preceding pressure pulse wave point of contact A that fights in time, diastolic wave rises and surpasses contraction wave and reaches optimum efficiency.Instead fight that its waveform and wave amplitude do not have significant change 55 minutes the time, be subjected to breathe influence little.Though the ear-lobe pulse wave also can reflect the anti-effect of fighting to a certain extent, can't determine the time phase of the initial rising point of ear-lobe pulse wave, waveform and amplitude change are bigger after counter fighting one hour.
Fig. 4 is a program flow diagram of realizing the general microcomputer fully-automatic extracorporeal reverse beating system, and the setting of initiation parameter is the parameter that the encephalopathy class is set among the figure, promptly selects the anti-treatment of fighting of encephalopathy class patient behind the program start automatically.The setting of interrupt vector is to be used for three interrupt service routines, so that finish the functions such as control of electromagnetic valve switch timing, image demonstration and digitized clock in real time.Before system began to fight for patient is anti-treatment, system all will generate data record format, to write down the various state of an illness parameters of patient in the anti-process of fighting, is convenient to the doctor and in time understands and grasp conditions of patients.
The present invention use ultrasonic flowmeter from temporo tremulous pulse (or radial artery, common carotid artery) detect counter fight preceding, the time blood flow show in the enterprising line number value of the CRT of 8088 microcomputers, as the external counterpulsation efficacy criteria.
Anti-controller chassis Fig. 1 that fights of the present invention makes the hardware plate, is inserted in 8088 cabinets as the expansion board of 8088 micro computers.Output drives, fills, deflated electromagnetic valve device and air bag are prior arts.
The present invention is as a kind of mechanical assistance EGR of non-invasive, can treat multiple ischemic disease such as coronary heart disease, cerebral arteriosclerosis, cerebral thrombus, cerebral infarction, embolism of central retinal artery, ischemic optic atrophy, ischemic disease of limb etc., because this device is control fully automatically, so except being applicable to medical institutions, also be applicable to family health care and rehabilitation aspect.
