Abstract
Disclosed is a positive and negative pressure gas path circulation type external pulse apparatus, adopting a computer monitoring system and through an electromagnetic valve to time and to inflate and exhaust gases to a gas bag sequentially. Compressed air passes through an air tank and the electromagnetic valve to inflate gases into the gas bag, the gas exhausted by the gas bag passes through the electromagnetic valve and drains into a negative pressure can to send to an air compressed pump again and the positive and negative pressure gas path circulation system is formed. The positive and negative pressure gas path circulation type external pulse apparatus is small size and simple device, which can make the gas bag which puts pressure on the limbs and the buttocks of a human body exhausted thoroughly and cleanly to decrease the pressure on the veins of the human body and to decrease the afterload of a heart further. Thereby, the treating effect on diseases is improved.
Description
This utility model belongs to promotion systemic blood circulation physical therapy appliance.
The disclosed enhanced external counterpulsation device of Chinese patent CN85200905U and CN87200288U, it is to pass through Computerized monitor system, by solenoid control extremity air bag and buttocks air bag are carried out timing and sequentially fill aerofluxus, at diastole, air bag is inflated in order by far-end to near-end, stresses on corresponding limbs of human body and buttocks, blood flow is concentrated at diastole to be poured into above the waist, improve diastolic pressure, thereby increased coronary flow, improved blood supply of cardiac muscle; Extremity air bag and buttocks air bags before heart enters systole, the pressure of pressurized portion is removed, and systolic arterial pressure decreases, and has alleviated cardiac afterload, and myocardium keto consumption thereby minimizing are treated the effect of coronary heart disease thereby reach counter fighting.Yet enhanced external counterpulsation device, the forced air of air bag are to be source of the gas by air pressure pump, by the computer monitor solenoid control.And the aerofluxus of air bag is to be controlled at heart by computer to enter the exhaust plug of systole with the front opening electromagnetic valve, air bag relies on the counteracting force of limb muscle and the pressure in the capsule to arrange naturally to atmosphere, because the distribution valve body of this electromagnetic valve is an open type, so the gas in the air bag is incomplete to airborne release, residual compression has positive 0.1kg/cm in its air bag
2About (gauge pressure), be that heart is removed not thorough at the pressure of systole limbs pressurized portion, blood vessel still receives impressed pressure, and patient is the state at pressurized during treating always, and a kind of sticky feeling is arranged, for a long time treatment, can make patient's limbs produce feeling of numbness, this air bags is not thorough, and the compressing vein blood vessel can increase the cardiac afterload burden, is a kind of adverse factors to treatment of diseases.In order to overcome the shortcoming of above-mentioned external counterpulsation apparatus, the purpose of this utility model is that a kind of air bags that can make of development is thoroughly clean, needn't adopt the positive negative pressure external counterpulsation apparatus of lower limb fluid pressure type again, adopt the vacuum pump pumpback to make the complicated like that external counterpulsation apparatus of liquid capsule emptying as 1971 32 volumes of U.S.'s cardiovascular magazine the 10th interim report.
External counterpulsation apparatus provided by the utility model is achieved in that the distribution valve body that computer is controlled the electromagnetic valve in the enhanced external counterpulsation device is changed into closed by open type, air bag institute expellant gas is collected in the negative-pressure cup with the check valve of make-up gas, this negative-pressure cup is connected with the air inlet of air pressure pump again, gas directly is transmitted back to compressor pump, when working, air pressure pump forms a positive and negative pressure gas channel blood circulation like this, guaranteed that air bags is thoroughly clean, improved the therapeutic effect of illness.
The source of the gas of the external counterpulsation apparatus that this utility model provides adopts single-phase low noise not have the oil gas pump, the low-pressure compressed air that produces after this air pressure pump energized is sent into accumulator by gas pipeline, fill exhaust solenoid valve with several groups of manifold type then and be connected, each group electromagnetic valve is connected with corrugated tube with corresponding extremity air bag and buttocks air bag on the anti-bed of fighting.The aerofluxus of filling that the discharge duct of electromagnetic valve is connected with negative-pressure pipeline is moved with existing commercially available enhanced external counterpulsation device identical, comprise the extracorporeal counterpulsation assembly by a cover, the Computerized monitor system control that ecg amplifier, ear arteries and veins amplifier, display monitor central monitoring system, microcomputer or dedicated microcomputer, ADC, DAC, enumerator and LED etc. form.
Negative-pressure cup can adopt modular system, also can design voluntarily, makes the slack tank that can tolerate 1kg pressure with the common metal material, is equipped with the check valve of vacuum table and make-up gas on vacuum tank.
The circulating external counterpulsation apparatus of this positive and negative pressure gas channel has that volume is little, device is simple, and easy to use, air bags is thorough, and the pressure in the air bag can reach negative 0.1～0.2kg/cm
2(gauge pressure) reduces cardiac afterload, reduces 10mmHg after tested before the comparable improvement of systolic pressure, reaches preventing and treating the advantage that coronary heart disease illness curative effect improves.
Concrete feature below in conjunction with this external counterpulsation apparatus of description of drawings.
