Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a shock wave energy density measuring device. Background Art

[0002] Energy density detection tooling is widely used in various extracorporeal pressure wave therapy equipment. When performing extracorporeal shock wave energy density detection, existing energy density detection devices mainly rely on visual inspection to determine the trajectory of the weight's movement. When the weight moves in the transparent tube, the height of the weight's rise is determined in combination with the scale on the transparent tube. Since there are certain errors in visual inspection angles and judgments based on feeling, the test results are inaccurate, which will affect the therapeutic effect of the extracorporeal shock wave.

[0003] The invention patent with patent announcement number CN109668666A discloses a test device and method for detecting the energy density of extracorporeal shock waves. The moving distance of the mass block (weight) is automatically detected by the corresponding detection device, which can avoid the uncertain errors existing in manual visual inspection.

[0004] However, the above energy density testing equipment still has the problem that the weight may fly out of its long tube when the force received is large enough, affecting the detection; at the same time, the middle block cannot automatically guide the center of the gun body to align with the center position of the weight, and manual adjustment and alignment are required. Manual alignment requires sufficient experience and is also relatively troublesome to operate; the vertical installation of the long tube or the perpendicular installation with the base can be achieved by the middle block alone. If the middle block is too long, it will affect the observation of the initial height of the weight. If it is too short, the numerical guidance of the long tube cannot be guaranteed, which affects the measurement accuracy. Summary of the invention

[0005] The utility model aims to solve the problems in the existing energy density detection device that when the weight is subjected to a large force, the weight will fly out of the transparent tube, affecting the detection, and the gun body and the center of the weight cannot be automatically aligned, and it is impossible to take into account the observation of the initial height of the weight and the verticality of the transparent tube. A shock wave energy density measuring device is provided, which prevents the weight from flying out by arranging a limit block on the top of the tube body, and realizes the alignment of the center of the tube body with the center of the gun body by a guide block, without the need for manual special alignment work, and the tube body is clamped and fixed by a plurality of clamping blocks, thereby ensuring its verticality without affecting observation.

[0008] The integral bracket includes a rectangular plate and a triangular plate, and the two right-angled sides of the triangular plate are respectively fixedly connected to the middle part of the side of the rectangular plate and the top of the base. A plurality of mounting bases and pistol clamping blocks are fixedly arranged on the side of the rectangular plate away from the triangular plate. The pistol clamping block is used to clamp the gun body. A clamping block is fixedly arranged on each of the mounting bases, and the clamping block is used to clamp the fixed tube body. The tube body is clamped by a plurality of clamping blocks to avoid a single clamping block being too long and affecting the observation of the weight.

[0009] Preferably, a laser distance measuring sensor is fixedly provided on one side of the top of the integral bracket, and the laser distance measuring sensor is located directly above the tube body, and the height position change of the weight is detected by the laser distance measuring sensor.

[0010] Preferably, the lower clamping block and the integral bracket are both fixedly connected to the base by bolts, so that the lower clamping block and the integral bracket are vertically fixedly mounted on the base.

DETAILED DESCRIPTION

[0025] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0026] like Figure 1 to Figure 3As shown, this embodiment provides a shock wave energy density measuring device, including a base 1, on which an integral bracket and a lower clamping block 2 are arranged, and the lower clamping block 2 and the integral bracket are fixedly connected to the base 1 by bolts to achieve fixed installation of the integral bracket and the lower clamping block 2, and the integral bracket includes a rectangular plate 9 and a triangular plate 10, and the two right-angled sides of the triangular plate 10 are respectively fixedly connected to the middle part of the side of the rectangular plate 9 and the top of the base 1, and a plurality of mounting bases 11 and a pistol clamping block 16 are fixedly arranged on one side of the rectangular plate 9 away from the triangular plate 10, and the mounting base 11 and the pistol clamping block 16 are fixedly connected by bolts. It is fixedly connected to the rectangular plate 9 to achieve installation and fixation. A gun body 3 is arranged on the lower clamping block 2. The gun body 3 of the utility model is a pneumatic ballistic extracorporeal shock wave therapy instrument handle with the authorization announcement number CN217138621U. The pistol clamping block 16 is used to clamp the gun body 3. The gun body 3 is installed and the clamping degree of the gun body 3 is adjusted by the pistol clamping block 16, and the gun barrel of the gun body 3 is ensured to be vertical. Since the overall bracket adopts a structure in which the rectangular plate 9 and the triangular plate 10 are integrally formed, it is easier to determine the vertical state with the base 1 through the plate surface of the rectangular plate 9, and it is easier to observe or detect the parallelism of the tube body 6 and the side of the rectangular plate 9.

[0027] A guide block 4 is arranged at the upper end of the gun body 3, and a mounting hole matching the outer side of the upper end of the gun body 3 is arranged in the guide block 4, and a guide groove 5 penetrating the top of the guide block 4 is arranged on the upper side wall of the mounting hole, and a tube body 6 is installed in the guide groove 5. When the guide block 4 and the guide groove 5 thereon are used, the center of the gun rod of the gun body 3 and the center of the tube body 6 are automatically aligned when the guide block 4 and the tube body 6 are installed. A limit block 7 is arranged at the upper end of the tube body 6 extending out of the guide groove 5, and the limit block 7 is used to prevent the weight 8 from flying out of the tube body 6 and its working range, thereby ensuring safety. A weight 8 is provided, and there is a gap between the side of the weight 8 and the inner wall of the tube body 6. The tube body 6 adopts a hollow transparent quartz tube, and a scale is provided on the tube body 6. The weight 8 can freely fall in the tube body 6. The shock wave emitted by the gun body 3 is automatically aligned with the center of the tube body 6 and the center of the gun barrel of the gun body 3 through the guide block 4 during installation, and then the center of the gun barrel of the gun body 3 is automatically aligned with the center of the weight 8, so that the shock wave emitted by the gun body 3 acts directly below the weight 8, ensuring that the weight 8 moves upward under the action of the shock wave.

[0028] A clamping block 12 is fixedly arranged on each of the mounting bases 11, and the clamping block 12 is used to clamp and fix the tube body 6. The verticality of the tube body 6 is achieved by the cooperation of multiple clamping blocks 12, which effectively avoids the situation when only one clamping piece fixes the tube body 6. If the vertical length of the clamping piece is too long, although the tube body 6 can be guaranteed to be vertical, it will block the scale and affect the observation of the movement trajectory or initial height of the weight 8. If the vertical length of the clamping piece is too short, the vertical state of the tube body 6 cannot be guaranteed.

[0029] The clamping block 12 is threadedly connected to one side with a butterfly screw 14. The clamping block 12 is adjusted by the butterfly screw 14. The clamping degree can be determined by the butterfly screw 14 to avoid looseness that affects the accuracy of the test result.

[0030] A laser distance measuring sensor 13 is fixedly arranged on one side of the top of the integral bracket. The laser distance measuring sensor 13 is a laser displacement distance measuring sensor with a model of BL. The laser distance measuring sensor 13 is located directly above the tube body 6. A right-angle plate 15 is fixedly connected to the top of the rectangular plate 9 by bolts. The laser distance measuring sensor 13 is passed through and fixedly arranged on the horizontal plate of the right-angle plate 15. The moving distance of the weight 8 is detected by the laser distance measuring sensor 13 to avoid data errors caused by visual observation.

[0031] When in use, first complete the installation of the device, install the overall bracket on the base 1, then clamp the gun body 3 with the pistol clamping block 16, then install and fix the lower clamping block 2, and achieve the installation of the gun body 3 and ensure that the gun body 3 is in a vertical state through the cooperation of the lower clamping block 2 and the pistol clamping block 16; install and fix the mounting base 11 on the rectangular plate 9, then install the guide block 4 on the lower part of the tube body 6, clamp the tube body 6 with the clamping block 12, turn the butterfly screw 14, adjust the tightness, and ensure that the tube body 6 is in a vertical state, place the weight 8 in the tube body 6 and slowly slide vertically to the bottom (the weight 8 can first drip a few drops of lubricating oil on the surface to effectively reduce the friction with the inner wall of the tube body 6 to ensure the accuracy of the test data), then keep the whole horizontal, install and fix the laser ranging sensor 13, and then start the test work.

[0032] During the installation of the tube body 6, the weight 8 is automatically aligned with the center of the gun barrel of the gun body 3 through the action of the guide block 4, and when the tube body 6 and the gun barrel of the gun body 3 are ensured to be in a vertical state, the gun barrel of the gun body 3 is located directly below the tube body 6 and the weight 8. The gun body 3 is started, and the shock wave emitted by the gun body 3 causes the weight 8 to move upward, and falls back to its original position after reaching the highest point. During this process, the laser ranging sensor 13 automatically detects the moving distance of the weight 8, and sends the monitoring data back to the host for calculation to complete the detection.
