Abstract

The utility model relates to an external counterpulsation device, in which air charge and discharge of an air bag is controlled by an electromagnetic valve in a timing and successive manner, an air compressor pump, an air receiver and the electromagnetic valve are connected by pipelines; limb air bags and a backside air bag on a counterpulsation bed are connected by the pipelines; the utility model is characterized in that a distributing valve body of the electromagnetic valve is sealed; a discharge air flows into a negative pressure tank provided with a check valve through the pipeline; and the negative pressure tank is connected with an air inlet of the air compressor pump, thereby, forming a positive and negative pressure gas circuit circulation system. The external counterpulsation device has small volume and simple device, and can decrease pressure on human veins in a manner of complete discharge of air in the limb air bags and the backside air bag and further decrease cardiac afterload, thereby improving disease treatment effect.

Description

Novel external counterpulsation unit

Technical field

This utility model relates to the novel external counterpulsation unit in the medical device.

Background technology

Enhanced external counterpulsation device of the prior art, 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 get into the aerofluxus core of systole with the front opening electromagnetic valve, and 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, in its air bag there be about positive 0.1kg/ square centimeter gauge pressure residual compression, and promptly heart removes not thorough in the pressure solutions 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.

Summary of the invention

This utility model technical problem to be solved is the deficiency that overcomes prior art, and novel external counterpulsation unit is provided, and utility model solves the technical scheme that its technical problem adopted and is: the novel external counterpulsation unit that this utility model provided is to realize like this; Regularly and control air bag through electromagnetic valve with passing through preface and fill deflated external counterpulsation apparatus; Connect air pressure pump with pipeline, accumulator and electromagnetic valve, and by extremity air bag and buttocks air bag on the anti-bed of fighting of pipeline connection; The distribution valve body that it is characterized in that electromagnetic valve is closed; Discharge gas and be connected with a negative-pressure cup with check valve through pipeline, negative-pressure cup is connected with the air pressure pump air inlet, forms a positive and negative pressure gas channel blood circulation; 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 through 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, monitor, microcomputer or dedicated microcomputer, ADC, DAC, enumerator and LED etc. form.

Negative-pressure cup can adopt modular system, also can design voluntarily, processes the slack tank that can tolerate 1kg pressure with the common metal material, on vacuum tank, is equipped with the check valve of vacuum table and make-up gas.

The beneficial effect of this utility model is; This ECP device volume is little, and device is simple, can make to stress on human limb and thoroughly totally reduce the pressure to human vein with the buttocks air bags; Further reduce cardiac afterload, thereby improve disease therapeuticing effect.

Description of drawings

The fundamental diagram of the circulating external counterpulsation apparatus of the positive negative pressure of Fig. 1.

The electromagnetic valve one assembly air valve body structure chart of the existing enhancing external counterpulsation apparatus of Fig. 2.

The electromagnetic valve distributing valve body structure figure of this novel external counterpulsation unit of Fig. 3.

Among the figure: air pressure pump 1, accumulator 2, electromagnetic valve 3, air bag 4, negative-pressure cup 5, check valve 6, charge valve 7, air bleeding valve 8, D1, D2, D3, D4, D5, D6, D7, D8 are air vent channel

The specific embodiment

Concrete detailed description below with reference to description of drawings this utility model being done; Shown in accompanying drawing, after source of the gas air pressure pump 1 energized of external counterpulsation apparatus, producing does not have the clean low-pressure compressed air of oil; Gas gets into accumulator 2 through pipeline; Get into several groups then and fill exhaust solenoid valve 3, each group electromagnetic valve directly is connected with corresponding one group of air bag 4, before human heart gets into systole, is opened by the air bleeding valve of Computerized monitor system control electromagnetic valve 3; Make the negative pressure of the Compressed Gas dependence negative-pressure cup 5 in the air bag enter negative-pressure cup rapidly; Negative-pressure cup 5 air inlets direct and air pressure pump are connected, and during compressor pump work, make negative-pressure cup form negative pressure simultaneously.And the gas of compressor pump relies on check valve 6 compensation of make-up gas, thereby accomplishes a positive and negative pressure gas channel blood circulation.

During the electromagnetic valve inflation, when charge valve 7 was upwards mentioned, air bleeding valve 8 was closed, and the D5 end face is shut, and the compressed air of being sent here by compressor pump injects pore D1 hole, and the D2 that flows through, D3, D4 flow to airbag aeration.

During the electromagnetic valve aerofluxus, charge valve 7 is closed, and when the D2 channel end surface was shut, air bleeding valve 8 was upwards mentioned, and the gas in the air bag is flowed through D4, D5 to airborne release.

In electromagnetic valve when inflation,, air bleeding valve 8 was closed when charge valve 7 was upwards mentioned, and the D5 end face is shut, and the compressed air of being sent here by compressor pump is by blowhole D1, and gas is flowed through hole D2, D3, D4 passage to airbag aeration.

During the electromagnetic valve aerofluxus, charge valve 7 is closed, and air bleeding valve 8 was upwards mentioned when the D4 channel end surface was shut, and the D7 hole that the double dot dash line of the both sides before and after passage D4, D5, D6 of the gas in the air bag is represented flows to negative-pressure cup toward the D8 steam vent.

Embodiment recited above describes the preferred implementation of this utility model; Be not that design and scope to this utility model limits; Under the prerequisite that does not break away from this utility model design concept, common engineers and technicians make the technical scheme of this utility model in this area various modification and improvement all should fall into the protection domain of this utility model; The technology contents that this utility model is asked for protection all is documented in claims.
