Description
This utility model belongs to the physical therapy appliance of cardiac stimulation.
The disclosed external counterpulsation apparatus of Chinese patent CN85200905U is a kind of advanced in the world external counterpulsation apparatus.It adds on the basis of extremity air bag uses the buttocks air bag; Adopting the micro veneer machine monitoring to fill aerofluxus carries out regularly and the system of sequential control; Its source of the gas has adopted the low pressure and mass flow oil-free diaphragm pump, do not need high-pressure air source, but since it used be a kind of air pressure pump of single-iris, power consumption is big, need to drive with threephase motor, can only under being the alternating current power supply of 380V ± 10%, use supply voltage, bring very big inconvenience to the user, and when operate as normal galloping, vibrations are big, noise is big, only the noise of air pump just reaches about 62 decibels, is not suitable for being installed in the treatment operating room, need build pump house in addition, increase user's investment, use again inconvenient.
The external counterpulsation apparatus that CN85200905U provided, the soundproof effect of air chest is poor, and several groups of electromagnetic valves in the air chest are installed complex structure respectively for every group.Extremity air bag on the anti-bed of fighting and buttocks air bag are directly to communicate with the air vent of electromagnetic valve respectively by pipeline, extremity air bag and buttocks air bag all carried out work after then counter-pulsation device started, according to clinical experience, can not use the upper arm air bag to some patient, and its device is provided with the upper arm air bag is filled deflated opening/shutting controller.And in a whole set of counter-pulsation device system, do not have the pressure protect facility,, may cause that patient's pressurized is too high, damage parts such as air bag when misoperation or when breaking down.
The purpose of this utility model is to overcome the shortcoming of said apparatus, makes to be applicable to 220 volts of supply voltages, cuts down the consumption of energy, and reduces noise, and is safe and reliable, improves therapeutic effect, makes things convenient for the medical worker to operate according to patient's state of an illness needs.
The utility model is achieved like this: the source of the gas air pump of external counterpulsation apparatus produces the low-pressure compressed air that does not have the oil cleaning after connecting 220V ± 10% power supply, gas passes through gas pipeline, expansion box, several groups in the air chest are filled exhaust solenoid valve, the air vent of electromagnetic valve puts elastic rubber pipe, the most handy corrugated tube is connected with extremity air bag and buttocks air bag on the anti-bed of fighting, electromagnetic valve fills the aerofluxus action and is controlled by the extracorporeal counterpulsation assembly, and the extracorporeal counterpulsation signal is triggered by the electrocardio assembly, take out electrocardio QRS wave group and detect the R ripple from human body, the sequential anti-signal of fighting of triggering for generating thus, start electromagnetic valve and do to fill the aerofluxus action, thereby the cardiomotility that reaches counter fight process and patient is synchronous.Fill aerofluxus and adopted one to overlap the micro veneer machine Computerized monitor system of forming by ecg amplifier, ear arteries and veins amplifier, display monitor central monitoring system, TP-801, ADG, DAC, enumerator and LED etc. with the sequential control electromagnetic valve of synchronous tracking for simultaneously counter fighting, show electrocardio synchronously, fill exhaust signal and pulse wave with two track three picture monitors; Scan mode can freeze image for the memory oscillography, is convenient to observe and the waveform that notes abnormalities; Computer detects the R ripple automatically from the QRS wave group; Computer is realized entirely synchronously, thereby is improved curative effect from the whole rhythm of the heart of motion tracking; Adopt digital filtering, suppress the 50Hz interfering signal fully.
During treatment, at patient's extremity and buttocks cover upper gasbag, Computerized monitor system utilizes patient's electrocardio QRS ripple to be baseline signal, at diastole, Continuous pressure-controlled air inflation is sequentially injected air bag in the accumulator, and secondly shank was thigh before this, be buttocks at last, airbag aeration stresses on the position that human body can pressurize, and blood is concentrated at diastole be poured into heart and head, has improved diastolic pressure, increase coronary flow, improve blood supply of cardiac muscle.The amplitude that diastolic pressure improves shows on the Firefly optical screen after ear arteries and veins transducer detects.Before heart enters systole, air bags, the pressure of pressurized portion is removed rapidly, and the pressurized blood vessel restores, and the blood that the heart of being received is in time displaced has alleviated cardiac afterload, myocardial oxygen consumption thereby minimizing, thus reach the anti-therapeutical effect of fighting.In like manner, to the blood supply of other position such as brain, eye, kidney, extremity also be improved significantly, so its indication is extensively and play the inaccessible effect of medicine.
What the source of the gas air pump of external counterpulsation apparatus provided by the utility model adopted is that a kind of single-phase pair of diaphragm low noise do not have the oil gas pump, the clean compressed air that does not have oil of output, rated pressure 0.5 kilograms per centimeter
2, metered flow reaches 0.5 meter
3/ minute, with the alternating current power supply of 220V ± 10%, only 0.75 kilowatt of institute's wasted work rate, noise is lower than 57.5 decibels during operate as normal, and temperature rise is below 40 ℃.Air chest is cube casing made from plank, and two layers of puigging are arranged all around, now adopts commercially available foam plastics to be deadener, and is cheap, can reach sound isolation requirement.Several groups of electromagnetic valves in the air chest are the low pressure type of straight-through duplex, and have taked the manifold type valve body, and are simple in structure, dwindled volume and reduced vibrations.Electromagnetic valve can fill up on wall shake pad and be placed directly in the air chest, fills up after also can setting up shock-proof spring under solenoid valve seat and put into air chest on antivibration pad, and shock-proof effect is better like this.The pipeline that the gas outlet of electromagnetic valve is connected with air bag can fill the aerofluxus vibrations in order to reduce with straight-through rubber tube or plastic tube etc., increases the service life and adopts rubber bellows comparatively desirable.
Be equipped with a pair of calf bladder, a pair of thigh air bag, a pair of buttocks air bag and a pair of upper arm air bag on the anti-bed of fighting in this counter-pulsation device, load onto a gate valve at the air inlet of upper arm air bag, when patient do not shake will with upper arm air bag when pressurization can closing gate valve.In addition, the anti-bed of fighting is provided with silencer cover, and its silencer cover can be a monoblock type, also can be covering type etc., and this utility model has designed a kind of silencer cover of organ type, speciously makes things convenient for patient to get in and out of bed again.Below the anti-bed of fighting is full-closed structure, and two side plates can be dismantled, and convenient the installation overhauled, and air chest and expansion box can be installed in bed down.
This counter-pulsation device is equipped with spring pressure security air valve on expansion box.When supply gas pressure surpasses rated pressure, will open automatically and carry out aerofluxus, protect machine and patient's safety.
