Description
Technical field
This utility model relates to armarium, particularly relates to external counterpulsation apparatus.
Background technology
External counterpulsation apparatus, all with pulsation Pneumatically driven system, provides the pulsation air pressure synchronous with human pulse by pulsation Pneumatically driven system to counterpulsation bag.In the prior art, the pulsation Pneumatically driven system of external counterpulsation apparatus is primarily of air pump, air accumulator, three-way magnetic valve composition.Air accumulator has the gas keeping certain pressure, when three-way magnetic valve is opened, gas in air accumulator inputs counterpulsation bag by three-way magnetic valve, air pressure in counterpulsation bag is improved instantaneously, when three-way magnetic valve is closed, counterpulsation bag outwards releases gas by three-way magnetic valve, so circulates, three-way magnetic valve periodically opens and closes, and makes counterpulsation bag produce the pulsation air pressure synchronous with human pulse.The gas that air accumulator is released is supplemented by air pump.
But, this pulsation Pneumatically driven system be made up of air pump, air accumulator, three-way magnetic valve that existing external counterpulsation apparatus adopts, not only bulky but also heavy, account for the weight and volume of a whole set of external counterpulsation apparatus more than 50%, constrain external counterpulsation apparatus to lightweight, miniaturization.
Utility model content
The purpose of this utility model is to provide a kind of direct-drive type external counterpulsation apparatus, and this direct-drive type external counterpulsation apparatus can realize lightweight, miniaturization.
This utility model is achieved in that direct-drive type external counterpulsation apparatus, comprise the counterpulsation bag be enclosed within human body, and for counterpulsation bag provide pulsation air pressure pulsation Pneumatically driven system, described pulsation Pneumatically driven system is by the elastic bag of variable volume, and elastic bag being imposed to the pressurizing unit composition of periodically extruding force, described elastic bag is communicated with counterpulsation bag by trachea.
As preferred forms or improve further, this utility model also can adopt following attached technical scheme.
Described pressurizing unit is pressed in the briquetting on described elastic bag by top and drives the reciprocating driving mechanism of briquetting to form.
The described reciprocating driving mechanism of driving briquetting is made up of motor and leading screw and nut mechanism, the screw mandrel of leading screw and nut mechanism or nut are connected with described motor, correspondingly, the nut of leading screw and nut mechanism or screw mandrel are connected with described briquetting, by leading screw and nut mechanism, the reciprocating rotation of described motor are converted into the linear reciprocating motion of described briquetting.
Described elastic bag is connected with inflator pump.
The utility model has the advantages that, pulsation air pressure needed for counterpulsation bag obtains by directly extruding elastic bag, without the need to laying in gases at high pressure, eliminate the bulky and air accumulator of heaviness, elastic bag can be made with light materials such as rubber, volume and weight is more much smaller than air accumulator, makes external counterpulsation apparatus be achieved lightweight, miniaturization.In addition, this utility model also eliminates the three-way magnetic valve acted frequently, and improves the ruggedness of external counterpulsation apparatus.

Detailed description of the invention
According to a kind of direct-drive type external counterpulsation apparatus that this utility model provides, as shown in Figure 1, comprise the counterpulsation bag 1 be enclosed within human body, and for counterpulsation bag 1 provide pulsation air pressure pulsation Pneumatically driven system.Described pulsation Pneumatically driven system by the elastic bag 2 of variable volume, and imposes the pressurizing unit composition of periodically extruding force to elastic bag 2.Described pressurizing unit is pressed in the briquetting 3 on elastic bag 2 by top and drives the reciprocating driving mechanism of briquetting 3 to form.Described driving mechanism is made up of motor 4 and leading screw and nut mechanism, and the screw mandrel 5 of leading screw and nut mechanism is connected with motor 4, and correspondingly, the nut of leading screw and nut mechanism is fixedly connected with briquetting 3, and nut and briquetting 3 are drawn as a component by Fig. 1.Motor 4 drives screw mandrel 5 reciprocating rotation, is converted into the linear reciprocating motion of nut and briquetting 3, thus imposes periodically extruding force to elastic bag 2.Elastic bag 2 is communicated with counterpulsation bag 1 by trachea, imposes periodically while extruding force at briquetting 3 pairs of elastic bags 2, and in counterpulsation bag 1, generation is pulsed air pressure accordingly.Fig. 1 has only schematically drawn a counterpulsation bag 1, and in fact, an elastic bag 2 can multiple counterpulsation bag 1 in parallel.
Fig. 1 only schematically illustrates the pulsation Pneumatically driven system be made up of an elastic bag 2 and described pressurizing unit.In a complete external counterpulsation apparatus, arrange the pulsation Pneumatically driven system described in three covers, can complete the sequential pressurization protocols of counterpulsation, whole external counterpulsation apparatus, with patient's electrocardiosignal do action, realizes treating the counterpulsation of patient.
As a kind of equivalent change structure, the screw mandrel 5 of above-mentioned leading screw and nut mechanism can be fixedly connected with briquetting 3, correspondingly, the nut of leading screw and nut mechanism is connected with motor 4, motor 4 drives nut reciprocating rotation, is converted into the linear reciprocating motion of screw mandrel 5 and briquetting 3.
The reciprocating rotation of motor 4 is controlled by a set of control system.The basic functional principle of this control system is, gather electrocardiosignal by electrocardioelectrode from patient body by electrocardiogram acquisition module and be transferred to control system, control system electrocardiosignal is as triggering signal, produce through computed in software and add decompression Signal transmissions to motor 4, motor 4 rotates forward or backwards according to adding depression signal.
In another embodiment shown in Fig. 2, the basis of Fig. 1 has been set up an inflator pump 6 be connected with elastic bag 2, be convenient to first use external counterpulsation apparatus time inflate for elastic bag 2.Counter-pulsation device duration of work in vitro, inflator pump 6 is without the need to work.
Drive the reciprocating driving mechanism of briquetting 3, except adopting above-mentioned leading screw and nut mechanism, other known mechanical transmission mechanisms can also be adopted.Such as, adopt rack and pinion mechanism, the reciprocating rotation of motor and gear is converted into the linear reciprocating motion of tooth bar and briquetting 3, or employing linkage, moved back and forth by connecting rod drive briquetting 3, and so on.
