[0030] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0031] In addition, the technical features involved in different implementation manners of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] When performing an impact test on the balloon in this embodiment, the balloon is placed in a water tank, and then a hydrophone is used to measure the sound pressure at different positions along the radial direction of the balloon and at different positions in the circumferential direction of the balloon in the water tank, and finally the impact force of the balloon is measured by the magnitude of the sound pressure.

[0033] As Figure 1 and Figure 2 shown in a specific implementation manner of the energy measurement device, taking the signal transceiver structure 1 as a hydrophone and the measured part as a balloon as an example for description, to simulate the shock wave generated by the balloon in the blood vessel, including a box body 2, a pair of installation components 3 and a measurement component provided in the box body 2. Of course, this measurement device can also be used to measure other energies, such as ultrasonic waves, etc.

[0034] The box body 2 is a cuboid made of a transparent rigid material, such as tempered glass, for convenient observation of the measurement situation, and has an accommodation space. The accommodation space is open, and a wedge-shaped absorption layer for absorbing energy reflection is provided on the inner surface. Of course, the box body 2 can also be a cube, a cylinder, etc., and no specific limitation is made here. During measurement, the box body 2 is filled with water. For convenient drainage, a drain valve 4 is provided at the bottom corner of the box body 2.

[0035] A pair of mounting components are respectively arranged on a pair of opposite side walls of the box body 2, and the pair of mounting components are suitable for mounting the measured piece. The mounting component includes a mounting disc 5 for fixing to the side wall of the box body 2 and a rotating structure 6 arranged on the mounting disc 5. An installation hole for fixing the end of the measured piece is arranged on the rotating structure 6. The balloon is generally delivered into the human body through a catheter. The catheter is sleeved on a guide wire. The inner diameter of the installation hole is adapted to the outer diameter of the catheter. The rotating structure 6 can be connected to a micro motor, and driven by the micro motor, the balloon rotates around the central connection line of the pair of mounting components to facilitate omnidirectional measurement of the shock wave emitted by the balloon.

[0036] The measuring component includes a bracket 7 arranged on the side wall of the box body 2, and a first adjustment structure, a second adjustment structure, a distance measuring structure and a signal transceiver structure arranged on the bracket 7. The bracket is L-shaped, including a first frame body 8 arranged horizontally and a second frame body 9 arranged vertically. The first frame body 8 extends towards the center of the box body 2, and the second frame body 9 extends towards the bottom of the outer side wall of the box body 2. The first adjustment structure and the second adjustment structure are both arranged at the first end of the bracket 7 extending into the box body 2, that is, on the first frame body 8. The first adjustment structure and the second adjustment structure are both slidably connected to the first end. The sliding directions of the first adjustment structure and the second adjustment structure are different and both are perpendicular to the central connection line of the pair of mounting components. Of course, this angle can also be other angles as long as it can meet the requirement of omnidirectional measurement of the shock wave emitted by the balloon.

[0037] As Figure 2 shown, a first slide rail 10 is arranged at the first end of the bracket 7. The first adjustment structure includes a first slider 11 slidably connected to the first slide rail 10 and a first fastener 12 penetrating through the first slider 11. The first fastener 12 is a threaded rod, and the first fastener 12 is suitable for fastening the first slider 11 to the first slide rail 10 after the first slider 11 slides to a predetermined position. A second slide rail is arranged on the side of the first slider 11 away from the first slide rail 10. The second adjustment structure includes a second slider 13 slidably connected to the second slide rail and a second fastener 14 penetrating through the second slider 13. The second fastener 14 is a threaded rod, and the second fastener 14 is suitable for fastening the second slider 13 to the second slide rail after the second slider 13 slides to a predetermined position. The extending directions of the first slide rail 10 and the second slide rail are perpendicular to each other, that is, the extending direction of the first slide rail 10 is the horizontal direction, and the extending direction of the second slide rail is the vertical direction. The distance measuring structure is arranged at the first end of the bracket 7 and includes a first distance measuring piece and a second distance measuring piece parallel to the extending directions of the first slide rail 10 and the second slide rail respectively. Specifically, the first distance measuring piece and the second distance measuring piece are both micrometers, which can ensure the accuracy of position adjustment.

[0038] On the side of the second slider 13 away from the second slide rail, there is also a connecting arm 15. The connecting arm 15 extends downward along the height direction of the box body 2. The signal transceiver structure 1 is arranged at the end corresponding to the center connection line of the connecting arm 15 and a pair of the mounting components, and the detection end face of the hydrophone is arranged parallel to the center connection line of a pair of the mounting components. During specific measurement, a plurality of electrodes are circumferentially arranged at intervals along the axial direction of the catheter inside the balloon, and the detection end face of the hydrophone is arranged parallel to at least one electrode. The signal transceiver structure 1 is adapted to receive the energy generated by the electrodes on the balloon and send a signal to the controller. In other embodiments, the signal transceiver structure 1 is adapted to emit a signal to the electrodes on the balloon to generate a shock wave, and after receiving the energy, send the signal to the controller.

[0039] On the side wall of the box body 2, there is a slideway 16 arranged circumferentially. The slideway 16 is arranged near the top of the side wall. The second end of the bracket 7 is provided with a sliding module slidably connected to the slideway 16. The slideway 16 is formed on a mounting plate, and the mounting plate is fixed to the side wall of the box body 2. The arrangement of the slideway 16 can, on the one hand, provide a mounting port for the bracket 7 to achieve a sliding connection with the bracket 7, and on the other hand, can also strengthen the structural strength of the box body 2 to ensure that the water pressure will not cause structural damage to the box body 2 when the box body 2 is filled with water. Specifically, the sliding module includes a sliding plate 17 slidably connected to the slideway 16, a third slider 18 slidably connected to the sliding plate 17, and a third fastener 19 for positioning. The third fastener 19 is a threaded rod and is arranged on the third slider 18. The third slider 18 is fixed to the second frame body 9 of the bracket 7.

[0040] When it is necessary to measure the balloon, first install the balloon catheter on a pair of mounting components. Then adjust the position between the measuring component and the balloon through the third slider 18. Next, adjust the distances between the hydrophone and the balloon in the horizontal and vertical directions respectively through the first adjustment structure and the second adjustment structure, and achieve accurate adjustment with reference to the micrometer during the adjustment. Finally, the hydrophone receives the energy generated by the electrode on the balloon and sends a signal to the controller. When it is necessary to measure other positions of the balloon, just rotate the mounting component, and then drive the balloon to rotate. This device can achieve four-degree-of-freedom changes in the relative position between the hydrophone and the balloon, and can control the change of the detection direction of the hydrophone, enabling the detection surface of the hydrophone to point to the balloon at any time. The hydrophone signal acquisition and conversion module uses a high-precision sigma-delta structure converter to achieve high-precision acquisition and conversion of the hydrophone. This device can, through the human-computer interaction interface, achieve the setting of measurement parameters and the control and operation of the system; the human-computer interaction interface mainly realizes the setting of test parameters by the user, the export of data after testing, and the setting of the sound wave imaging screen. After the measurement process is completed, this device packs and stores the measurement data, and copies and exports the data as required. This device also has an imaging unit composed of an image solution and processing subsystem, which constructs a visual sound field graph based on the data transmitted back by the signal acquisition and conversion module, uses AI technology to correct the image results, analyzes the data results and the imaging, and gives suggestions for relevant interpretation results.

[0041] As an alternative implementation manner, the signal transceiver structure 1 can rotate around the extension line of the axis of the mounting component 3, or the bracket 7 can move circumferentially around the side wall of the box body 2, and then drive the signal transceiver structure 1 to rotate around the extension line of the axis of the mounting component 3, realizing omnidirectional measurement within a certain spatial range outside the balloon.

[0042] As an alternative implementation manner, the sliding module can also be connected to the controller and is adapted to automatically slide along the slide plate 17 under the action of the controller, realizing automatic movement along the side wall of the box body 2.

[0043] As an alternative implementation, the signal transceiver structure 1 can rotate around the central axis of the measured object, so as to perform an all-round measurement on the shock waves emitted from different positions of the balloon. Specifically, a pair of the mounting components 3 are arranged on the same side wall of the box body 2 at intervals along the height direction of the box body 2 through a connecting rod. Specifically, one end of the connecting rod can be fixed to the side wall of the box body 2, and the other end is provided with a mounting disc and a rotating structure. The extending direction of the first slide rail 10 is perpendicular to the central connection line of a pair of the mounting components 3, and the extending direction of the second slide rail is parallel to the central connection line of a pair of the mounting components 3. The first frame body 8 of the bracket 7 is rotatably connected to the second frame body 9, and the second frame body 9 is connected to a micro motor. Driven by the micro motor, the hydrophone is driven to rotate around the axis of the balloon. At this time, the box body 2 is preferably a cylinder. The slide way can be arranged in a circle at the same horizontal height along the outer side wall of the cylinder, or can be arranged in a spiral shape along the outer side wall of the cylinder, so that the hydrophone descends spirally to perform an all-round measurement on the shock waves emitted by the balloon. In the above embodiment, only one mounting component 3 can also be provided. At this time, the mounting component 3 is located at the center of the bottom wall of the box body 2. The extending direction of the first slide rail 10 is perpendicular to the axis of the mounting component 3, and the extending direction of the second slide rail is parallel to the axis of the mounting component 3. The second frame body 9 of the bracket 7 can rotate around the extension line of the axis of the mounting component 3.

[0044] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom still fall within the protection scope of the creation of the present utility model.
