Shock wave pneumatic hybrid external counterpulsation device

Technical Field

The invention belongs to the technical field of external counterpulsation, and particularly relates to a shock wave pneumatic hybrid external counterpulsation device.

Background

The external counterpulsation is a method for non-invasively pressing the lower half body in vitro, relieves and eliminates the symptoms of angina pectoris, improves the anoxic and ischemic states of important organs of the body, and is medical equipment for preventing and treating cardiovascular and cerebrovascular diseases. Generally, in vitro counterpulsation, air bags are wrapped on four limbs and buttocks, and the air bags are inflated and pressurized in the diastole of the heart, so that the blood in the artery of the limb is driven to return to the aorta, the diastolic pressure is obviously increased, the blood flow is increased for the heart, and the afterload of the heart is reduced; the air bag can exhaust air rapidly in the systole, the pressure is relieved, the systolic pressure in the aorta is reduced, the resistance in the cardiac ejection period is relieved to the maximum extent, and the blood flows to the far end in an accelerated way, thereby achieving the counterpulsation effect.

However, the existing mode of pressing the limbs of the patient by inflating the air bags has the defects of air leakage risk of the air channels, complex structure and complex air pressure control. And the existing external counterpulsation technology only produces action effect on a user on the dynamic effect of blood flow, and the function is too single, so that a better comprehensive effect cannot be realized.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide a shock wave pneumatic hybrid external counterpulsation device, which realizes better comprehensive effect by the cooperative cooperation of shock waves and pneumatic external counterpulsation.

In order to achieve the purpose, the invention adopts the following technical scheme:

a shock wave pneumatic hybrid extracorporeal counterpulsation apparatus comprising:

the binding belt is provided with fixing pieces at two ends for binding and fixing the binding belt on the limbs of a user;

an airbag fixed to the tether belt;

a shock wave generator fixed to the body of the binding band, the shock wave generator having a shock head abutting against the limb of the user when the binding band binds the limb of the user;

and the air supply assembly is provided with at least two branch pipes, wherein one branch pipe is communicated to the shock wave generator through an electromagnetic valve, and the other branch pipes are communicated to the air bag.

Compared with the prior art, the invention has the following technical effects:

the shock wave pneumatic hybrid external counterpulsation device provided by the invention is used by combining the shock wave generator and the air bag, and the shock effect of the shock wave generator is added in the compression and release process generated by periodic inflation and deflation of the air bag, and compared with the traditional pneumatic external counterpulsation, the device can only generate a hemodynamic effect;

In addition, because the shock wave generated by the shock wave generator also has the effect of extruding the blood vessel, the inflating quantity of the air bag is greatly reduced, and the volume and the weight of the external counterpulsation equipment are indirectly reduced.

Additional features and advantages of the invention will be set forth in the detailed description which follows.

As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, 2 and 3, there are shown schematic structural views of a pneumatic hybrid external counterpulsation device with shock waves according to an embodiment, which includes a binding band 10, an air bag 20, a shock wave generator 30 and an air supply module.

The binding band 10 mainly plays a role in supporting and fixing and is used for supporting and fixing parts such as the air bag 20, the shock wave generator 30 and the air supply assembly. Fixing parts are arranged at two ends of the binding belt 10 and used for binding and fixing the binding belt on limbs of a user, specifically in the embodiment, the fixing parts are magic tapes 11 arranged at two ends of the binding belt 10, in the specific use process, the magic tapes 11 are used for achieving pasting and fixing, and the binding belt 10 is bound on legs or arms of the user, so that the binding belt is simple and convenient.

The air cell 20 is fixed to the binding band 10, and the air cell 20 is mainly used to store air and generates an increase and decrease in volume during the processes of inflation and deflation, thereby generating a compression and relaxation effect on the user's limbs. Specifically, the air bag 20 is formed by heat sealing and tightly molding polyvinyl chloride PVC or TPU composite materials, and the single-layer thickness of the air bag 20 is 0.2 +/-0.02 mm.

The shock wave generator 30 is fixed to the body of the binding band 10, and the shock head 321 of the shock wave generator 30 is abutted against the limb of the user when the binding band 10 binds the limb of the user.

Referring to fig. 4, in the present embodiment, the shock wave generator 30 includes a housing 31 and a shock head assembly 32 disposed at one end of the housing 31, the housing 31 has a through trajectory 311, a bullet 33 is disposed in the trajectory 311, and a high-pressure gas inlet 34 is disposed at one end of the housing 31 away from the shock head assembly 32 and is provided with a solenoid valve 35 for controlling the input of high-pressure gas; the impact head assembly 32 comprises an impact head 321, a damping part 322 and a sealing ring 323, and an upper end cover 36 is arranged at one end of the impact head assembly 32 far away from the shell 31.

The gas supply assembly has at least two branch pipes, one of which is connected to the shock wave generator 30 via a solenoid valve, and the other branch pipes are connected to the airbag 20. Specifically, in the present embodiment, the gas supply assembly has a first branch pipe 41 and a second branch pipe 42, the gas supply assembly is supplied with high-pressure gas, one part of the high-pressure gas is input into the shock wave generator 30 via the first branch pipe 41 and the electromagnetic valve 35 connected thereto in a controlled step, and the other part of the high-pressure gas is input into the airbag 20 via the second branch pipe 42. It should be noted that, in the present embodiment, the interval of the air supply from the air supply module to the air bag 20 and the pressure of the air supply are controlled by the control system of the external counterpulsation device, which depends on the specific situation of different users, and this part of the technology belongs to the control technology of the existing pneumatic external counterpulsation, and the detailed description of the embodiment is omitted here.

In one embodiment of the present invention, the inflating time of the airbag 20 is 500ms, and the shock wave generator 30 is completed once in 10ms, so that the shock wave generator 30 is turned on and off 50 times by the electromagnetic valve 35 within 500ms, that is, 50 pulses are realized.

In the present invention, the shock wave generated by the shock wave generator 30 utilizes the energy conversion and transmission principle to generate energy gradient difference and torsional tension between tissues with different densities, and form cavitation effect to generate biological effect. Shock waves have strong tensile and compressive stresses and are able to penetrate any elastic medium, such as water, air and soft tissue.

In the technical scheme provided by the invention, through the high integration of the shock wave generator 30 and the air bag 20, the shock effect of the shock wave generator 30 is added in the compression and release process generated by the periodic inflation and deflation of the air bag 20, and compared with the traditional pneumatic external counterpulsation, the hybrid external counterpulsation device provided by the invention can only generate a hemodynamic effect; in addition, because the shock wave generated by the shock wave generator 30 also has the effect of extruding the blood vessel, the inflation quantity of the air bag 20 in the invention is greatly reduced, and the volume and the weight of the external counterpulsation device are indirectly reduced.

According to the present invention, the airbag 20 is flat and is sewn and fixed to the middle of the binding band 10, and a through hole 21 is formed in the middle of the airbag 20 for the passage of the shock wave generator 30. By designing the air bag 20 to be flat, the inflated volume of the air bag is expanded to generate larger-area extrusion on the limbs of a user, and discomfort possibly generated by small-area extrusion is avoided.

According to the present invention, in order to improve the effect of the shock wave generated from the shock wave generator 30, a plurality of shock wave generators 30 are provided at the binding band 10. Specifically, 3, 4 or 5, the shock wave generators 30 are arranged at intervals along the length direction of the binding band 10.

According to the present invention, the width of the binding band 10 may be selected within a wide range, and an excessively small band width may cause discomfort after tightening the limbs of the user, and an excessively large band width may not only occupy an excessive volume but also have no benefit to external counterpulsation, but may rather reduce the timeliness and effectiveness of the compression of the air bladder 20, and preferably, the width of the binding band 10 is 15-20cm in the present invention.

According to the present invention, the air cell 20 is fixed to the binding band 10, and expands and compresses the user's limb after being inflated, and the volume expansion thereof is simultaneously performed toward both sides, but only the air cell adjacent to the user's limb side is effectively compressed, and for this reason, the binding band 10 of the present invention is further provided with a pressing piece (not shown) having both ends fixed to the body of the binding band 10, the body of the pressing piece being pressed against the outside of the air cell 20, and a pressing force is applied to the air cell 20 when it is inflated. Through the limit of the pressure stop sheet, the air bag 20 expands and extrudes to one side of the limb of the user as much as possible after being inflated, and the timeliness and effectiveness of counterpulsation are improved. Specifically, the pressure-stopping sheet is one of an elastic glass fiber sheet, an aluminum plate, a manganese steel plate and a resin strip, can bear certain pressure and force the air bag 20 to expand inwards, and the outer side of the pressure-stopping sheet is further coated with oxford for hiding the pressure-stopping sheet.

The foregoing shows and describes the general principles, essential features, and inventive features of this invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
