Description
Technical field the present invention relates to preestablish in a kind of medical domain the method for the anti-capsule bag operating pressure of fighting in the external counterpulsation apparatus.
Background technology so far, all external counterpulsation apparatus all are as the anti-driving force of fighting with air compressor both at home and abroad, operational mode is basic identical, promptly, according to the requirement of external counterpulsation program, surround the cyclic process that counterpulsation balloon on the user limbs carries out " inflation-venting " by controlling each, realize the user limbs are carried out the anti-work of beating of " tightening up-loosen ".
But these exist some common shortcomings with air compressor as the external counterpulsation apparatus of driving force:
[1] volume is big;
[2] noise is big in the running;
[3] whole cost height;
[4] because different patients' limbs thickness diversity ratio is bigger, counterpulsation balloon when binding sometimes tightly, pine sometimes, this makes control air bag inflation pressure difficulty that becomes.
[5] there is invalid plenum space in the counterpulsation balloon, increased the power consumption of air compressor.
In view of the above-mentioned deficiency that has pump source of the gas external counterpulsation machine to exist, all the time, the knowledgeable people is constantly carrying out research and is improving, the patent No. is that 93226047.0 utility model patent description discloses a kind of no source of the gas pump housing extracorporeal counterpulsation machine, this utility model utilizes patient's the anti-signal control electric magnet of fighting to be interrupted energising so that produce alternate the action of a magnetic field power, piston rod and leather cup are moved in cylinder and glide, be interrupted and be the gasbag inflation, become no pump source of the gas, in the anti-clothing of fighting of its design, increased the excessive bag of a fill liquid, be placed between patient's the limbs and gasbag.Imagination by this utility model inventor, this utility model has been omitted main equipments such as air compressor machine, oil water separator, air relief valve, gas receiver, the transition bag of fill liquid can be according to the solid surface distortion of human body, the space of limbs curved surface is filled up, save the discharge capacity of source of the gas, reached the purpose that not only reduces cost but also improve curative effect.
But, exist two following defectives if when implementing by the disclosed technical scheme of above-mentioned utility model patent description:
The one,, placing the fluid transition bag between limbs and air bag has just increased the volume that air bag wrapped up, and does not change the actuating pressure of air bag to limbs.For with mobile pressure transmission mediums such as gas or liquid, the shape of limbs, all equates without any influence stressed.This fluid transition bag does not have practical value in the application of external counterpulsation.
The 2nd,, place the not substantial minimizing airbag aeration of fluid transition bag demand.The inflation requirements of air bag still depends on the tightness of patient's limbs volume and air bag wrapping, still is according to the people and the time and different.When the airbag aeration demand was uncertain, inflating with the slip of solenoid actuated piston in cylinder was to be difficult to control aeration quantity and the blowing pressure.Promptly enable control, the control difficulty may be also bigger than traditional approach, realizes that cost is higher.
The response speed of control of the pressure of air bag and inflation-venting is very important governing factor in the external counterpulsation apparatus, above-mentioned traditional various external counterpulsation apparatus are because can not confirm the inflation requirements amount of each air bag in advance, so also just be difficult to stablize the control the blowing pressure and in time respond.
Summary of the invention the object of the present invention is to provide a kind of method that preestablishes the anti-capsule bag operating pressure of fighting in the external counterpulsation apparatus.
Theory analysis shows that people's blood pressure has individual peak.If the limbs surface is applied the pressure that is not less than this people's blood pressure peak, just can reach the purpose that limbs tissue and vascular flow are exerted pressure, blocked.By experiment as can be known, people's limbs are after being subjected on every side uniform pressure, the contraction of certain amplitude can appear, and pressure passed to blood flow, under the pressure that human body can bear, be pressed the decrement of scope limbs, generally be no more than 10% of the section of being pressed limbs volume, the amount of contraction of limbs girth also is no more than 10% of girth.The tradition external counterpulsation apparatus utilize these characteristics by the counterpulsation balloon on the limbs that surround the people being carried out suitable inflation and venting operate as normal.
Hence one can see that, if each counterpulsation balloon that surrounds on the user limbs in the external counterpulsation apparatus is inflated the pressure that makes intracapsular pressure reach setting in advance, and then counterpulsation balloon taked the cyclic process of " venting-inflation ", just can stablize the control the blowing pressure and in time respond.
According to above-mentioned analysis result, realize that first technical scheme of the object of the invention is such:
A kind of method that preestablishes the anti-capsule bag operating pressure of fighting in the external counterpulsation apparatus is characterized in that this method may further comprise the steps:
(a) the anti-capsule bag of fighting in the external counterpulsation apparatus is divided into work capsule bag and two parts of filling capsule bag;
(b) at first each work capsule bag is carried out the working media filling, loading equals predefined displacement volume;
(c) then each is filled the capsule bag and carry out the working media filling, fill the capsule bag until each and all reach predefined pressure, close the electromagnetic valve that each fills capsule bag correspondence, make that the loading of filling in the capsule bag is invariable.
Method of the present invention, the anti-capsule bag of fighting in its external counterpulsation apparatus is by separate work capsule bag and fill capsule bag be combined into, the outside is the binder that does not have retractility.
Described working media can be to have mobile any material, and the working media in work capsule bag and the filling capsule bag can be inequality.
When work capsule bag is carried out the working media filling, predefined displacement volume, be meant that one is not less than maximum compressibility that work capsule bag will hold the part limbs and fills working media volume change sum in one " loosening-tighten up " circulation in the capsule bag, wherein, the limbs maximum compressibility is no more than and is held 10% of limbs volume.
During pressure setting, reach predefined pressure in the filling capsule bag, be meant a force value that is not less than the user maximal blood pressure, this force value is not more than 40kpa usually.
During external counterpulsation apparatus work, control system is according to the program requirement, control the anti-driving mechanism work of fighting of each work capsule bag correspondence, each capsule bag of working is made decompression, compression motion respectively under the effect of the anti-driving mechanism of fighting, make working media wherein in the anti-enclosed space that constitutes between driving mechanism and the work capsule bag of fighting, flow back and forth, realize the action identical with traditional external counterpulsation apparatus.
As second technical scheme that has realization the object of the invention of constructed design with first technical scheme is such:
A kind of method that preestablishes the anti-capsule bag operating pressure of fighting in the external counterpulsation apparatus is characterized in that this method may further comprise the steps:

(b) then each anti-capsule bag of fighting is carried out working media and fill, all reach predefined pressure, close the electromagnetic valve of each anti-capsule bag correspondence of fighting, make that the loading of refuting in the capsule bag is invariable until each anti-capsule bag of fighting.
During pressure setting, scalable motion keeps predefined stroke, be meant when the anti-driving mechanism of fighting is done " loosening-tighten up " action, and the stroke of scalable motion wherein, usually, this stroke is no more than and is held 10% of limbs girth.
During pressure setting, reach predefined pressure in the anti-capsule bag of fighting, be meant the force value that is not less than the user maximal blood pressure, this force value is not more than 40kpa usually.
Described working media can be to have mobile any material.
During external counterpulsation apparatus work, control system requires the anti-capsule bag of fighting of the control direct driving of the anti-driving mechanism of fighting to carry out " loosening-tighten up " action according to program, thereby realizes the action identical with traditional external counterpulsation apparatus.The method that preestablishes the anti-capsule bag operating pressure of fighting in the external counterpulsation apparatus of the present invention, by preestablishing the anti-capsule bag operating pressure of fighting, make counter-pulsation device active force to the user limbs in the anti-process of fighting to preestablish, can get rid of all invalid filling spaces simultaneously.By preestablishing operating pressure, make system when entering duty, work capsule bag promptly is in predefined pressure state, and guarantees that when loosening, the anti-capsule bag of fighting is got back to initial condition in the course of the work, to the pressure disappearance of limbs; The anti-capsule bag of fighting is got back to predefined pressure again when tightening up.
It has following advantage:
1. during pressure setting, because of all working capsule bag and filling capsule bag and medium source all are in same pressure environment, so, whole system only needs a press detection sensor and the operating pressure that control sequence is all anti-capsule bags of fighting of may command, no matter and the limbs thickness of user, the fat or thin or anti-capsule bag tightness in when binding of fighting, always pressure is consistent.
2. saved air compressor in the traditional scheme and supporting big flow solenoid valve fully, provided cost savings significantly.
3. in the counter-pulsation device work process, working media or flow back and forth between driving mechanism and the work capsule bag counter fighting perhaps directly bears extruding and loosens in the anti-capsule bag of fighting, thereby realizes the action identical with traditional external counterpulsation apparatus.
4. the present invention can adopt any flowability material such as gas, liquid etc. are as working media preferably, and the working media that uses in each capsule bag can have nothing in common with each other.
Usually using more working media is gases such as air.
When adopting gas, then can adopt micro air pump as auxiliary source of the gas of filling as working media.Gas in the work capsule bag is disposable replenishing, and does not bleed off in the work process.Fight between driving mechanism and the work capsule bag even can not have valve counter, having overcome in the market, conventional bulk extracorporeal counterpulsation machine adopts the disadvantage of air compressor as power gas source.Make each counterpulsation balloon reach setting pressure by inflation in advance, guarantee the space that each limbs that held further compress without any needs on every side, reduced invalid inflation and pipeline loss, really realized with low cost, stable height, be suitable for the purpose of applying.
Another kind of working media commonly used is water, wet goods liquid.At this moment, as long as change the micro air pump in the above-mentioned gas medium scheme into the micro hydraulic pump, the material that each capsule bag, pipeline, valve etc. is replaced with suitable working media gets final product.
