Abstract
The utility model relates to a fast unloading device of an external counterpulsation device, which comprises a plurality of pairs of gas bags arranged on human limbs and an electromagnetic valve which is controlled by a computer and a control circuit. The electromagnetic valve can ensure the air charge and discharge time of the gas bag according to a heartbeat cycle. The control circuit comprises an electromagnetic valve power amplifying circuit and a power supply circuit, and is characterized in that the power supply circuit is provided with an electricity return circuit which can maintain continuously an air outlet of the electromagnetic valve to be in a state of opening when the power is off. The electricity return circuit comprises a charge and discharge electriccapacity C3 which are arranged in the power supply circuit and is merged with a filter electriccapacity C1, a relay and a resistance R1, wherein, the relay is an AC double contact relay. When the power supply is cut during a counterpulsation treatment, an air outlet can also cause an air discharge electromagnetic valve to work continuously till the air discharge valve can not close when an entire machine stops working. In such a way, air in the gas bags can all be discharged rapidly when the entire machine stops working under any situation, which ensures the safety of the treatment.
Description
Technical field
This utility model relates to a kind of medical apparatus, particularly a kind of quick relief device for the treatment of cardiovascular disease with external counterpulsation unit.
Background technology
The nearly 30 years effort of external counterpulsation unit process that can determine the treatment cardiovascular disease of airbag aeration evacuation time according to cardiac cycle that utilizes gas pressure intensity and control by computer and control circuit, now at home and abroad obtained using comparatively widely, it not only has excellent therapeutic effect to cardiovascular disease, and by improving blood circulation, all can produce useful effect to partes corporis humani's organ, but in being applied to clinical external counterpulsation unit at present, common existing when the patient being carried out outage suddenly takes place in the therapeutic process, and counter fighting when being in inflation, gas keeps a kind of pressurized state to patient's limbs, the patient is not felt well, the patient heavier as cardiovascular disease, also can cause pathological changes, at above-mentioned in therapeutic process existing safety problem, existing external counterpulsation unit is all by adopting the mode that increases an air bleeding valve, its ultimate principle is, this air bleeding valve is in closed condition when complete machine is worked, gas was discharged in this air bleeding valve can be opened also air bag when power interruptions, patient's pressurized is removed, but this design not only strengthens the complete machine cost because of need increase by a cover aerofluxus valve member, and because of this valve member because of less action easily makes the inner mechanicalness fault that produces.
Summary of the invention
The purpose of this utility model is at above-mentioned existing problems, providing a kind of need not increase the quick relief device that the aerofluxus valve member just can be implemented in the external counterpulsation unit that when outage discharge gas in the gas fast, and quick relief device on this basis has also that project organization is simple, the advantage of reliable in action.
The technical solution of the utility model is:
A kind of quick relief device of external counterpulsation unit, comprise and be placed on some on people's limbs air bag and by computer, what control circuit was controlled can determine that air bag fills the electromagnetic valve of evacuation time according to cardiac cycle, described control circuit comprises electromagnetic valve power amplifier and power circuit, wherein above-mentioned power circuit output end and electromagnetic valve power amplifier power supply electricity connect, electromagnetic valve power amplifier outfan plugs by lead and electromagnetic valve, be characterized in being provided with in the described power circuit when outage and the time can continue to keep in the electromagnetic valve exhaust ports in the electric loop of opening, described electric loop comprises and being arranged in the power circuit and the rectifying and wave-filtering capacitor C
1Mutually and connect charge and discharge capacitor C
3, relay and resistance R
1, wherein: described relay is for exchanging double-contact formula relay, and a contact of relay connects mutually with the computer output signal, another contact and resistance R
1Be connected, described relay coil and transformator join, described resistance R
1The other end be connected with power circuit.
This utility model owing to adopted is provided with in the built-in power circuit of external counterpulsation apparatus can continue to keep the electric loop that is in opening in the electromagnetic valve in the air bleeding valve when cutting off the power supply, when when the power supply source interruption is met in the anti-treatment of fighting, utilize in the electric loop capacitor discharge principle make exhaust valve port when complete machine quits work, also can make exhaust solenoid valve work on to air bleeding valve can not adhesive till, when complete machine is under any circumstance quit work, gas in the air bag all can be discharged rapidly, thereby has guaranteed the safety of treatment.In addition, this design need not to increase air bleeding valve, and the manufacturing cost of complete machine is minimized.
Description of drawings
Fig. 1 is this utility model schematic diagram.
The specific embodiment
This utility model as shown in Figure 1, a kind of quick relief device of external counterpulsation unit, comprise and be placed on some on people's limbs air bag and by computer, what control circuit was controlled can determine that air bag fills the electromagnetic valve of evacuation time according to cardiac cycle, described control circuit comprises electromagnetic valve power amplifier and power circuit, wherein above-mentioned power circuit output end and electromagnetic valve power amplifier power supply electricity connect, electromagnetic valve power amplifier outfan plugs by lead and electromagnetic valve, be characterized in being provided with in the described power circuit when outage and the time can continue to keep in the electromagnetic valve exhaust ports in the electric loop of opening, described electric loop comprises and being arranged in the power circuit and the rectifying and wave-filtering capacitor C
