Abstract
Description
Technical Field
[0001] The utility model relates to a test device for detecting the energy density of extracorporeal shock waves, and particularly to a divergent shock wave energy density detection device. Background Art
[0002] Shock wave therapy is a non-invasive treatment method widely used in the treatment of musculoskeletal diseases. The energy density of shock waves is one of the key parameters for measuring the treatment effect. If the energy density of the shock wave does not meet the standard, the shock wave cannot achieve the treatment effect. Therefore, before the equipment leaves the factory, the manufacturer needs to test whether the energy density of the extracorporeal shock wave equipment meets the standard.
[0003] When the existing shock wave energy density test device is used to test the energy density of extracorporeal shock waves, it mainly relies on visual inspection to judge the maximum height of the weight moving. The pistol of the extracorporeal shock wave is placed at the bottom of the transparent pipe. After the pistol is started, the impact force of the bullet acts on the center of gravity of the weight, and the weight starts to move upward along the inside of the transparent pipe. Then, the scale set on the transparent pipe is used to observe the moving distance of the weight. Since it is difficult to avoid the collision and friction between the weight and the inner wall of the transparent pipe when the weight moves in the transparent pipe, the test result will have a large error. In addition, there are certain errors in visual inspection, including the upward viewing angle or the downward viewing angle, and the reaction sensitivity of different people to moving objects all affect the test result, resulting in a large error in the finally calculated energy density of the extracorporeal shock wave and affecting the treatment effect of the extracorporeal shock wave.

[0030] Refer to Figures 1 - 5, this embodiment provides a divergent shock wave energy density detection device, the purpose of which is to improve the accuracy of shock wave energy density detection and reduce human error through automation technology. This shock wave energy density detection device adopts an automated detection technology to automatically measure the moving distance of the weight, effectively avoiding the error caused by manual visual inspection.
[0031] This shock wave energy density detection device includes a bracket 1, a base 2 and a sliding block 3 arranged on the bracket 1. A space for the sliding block 3 to move up and down is provided above the bracket 1 relative to the base 2. A detection member 4 is arranged above the space of the bracket 1, and this detection member 4 is used to detect the moving distance of the sliding block 3.
[0032] In the embodiment, a first support member 12 and a second support member 13 are arranged at the upper end of the column 11. An interval is provided between the first support member 12 and the second support member 13, and this interval provides the moving distance of the sliding block 3 up and down. An interval is formed between the first support member 12 and the second support member 13 arranged at the upper end of the column 11, providing a clear moving range for the sliding block 3.
[0033] At least three rods 14 are arranged within this interval. The at least three rods 14 are circumferentially equally spaced. The circumferentially equally spaced design of the at least three rods 14 encloses a cylindrical moving space, ensuring the uniformity and consistency of the movement of the sliding block 3. The three rods 14 are arranged vertically upward, and the sliding block 3 can perform a free-fall motion within the cylindrical moving space enclosed by the three rods 14.
[0034] The rods 14 and the sliding block 3 are made of stainless steel or aluminum alloy and are provided with a smooth surface to reduce friction and improve the smoothness of movement. Using stainless steel or aluminum alloy materials enhances the adaptability of the device to different environmental conditions and improves durability. The smooth surface and material selection facilitate cleaning and maintenance, contributing to the long-term stable operation of the equipment. At the same time, the dimensional fit between the rods 14 and the sliding block 3 is precisely controlled to avoid too tight or too loose a fit and reduce the friction caused by improper fit.
[0035] In this embodiment, the base 2 is slidably connected to the vertically upward column 11 of the bracket 1. The sliding setting of the base 2 can adjust the distance between the base 2 and the upper second support member 13, facilitating the placement of the sliding block 3 within the cylindrical moving space and being able to exactly place it at the shock wave generating end of the shock wave test piece during testing. A placement cavity 21 is arranged on the base 2 for placing the shock wave test piece, and the position of the placement cavity 21 corresponds exactly below the cylindrical moving space of the sliding block 3, facilitating the shock wave emitted by the shock wave test piece to exactly act on the directly below of the sliding block 3.
[0036] The base 2 is provided with a clamping member adapted to the placement cavity 21. The clamping member includes a clamping block 6 and a bolt 7. When the shock wave test piece is placed in the placement cavity 21, the clamping block 6 is fixed above the placement cavity 21 through the bolt 7, and the clamping end of the shock wave test piece is clamped and fixed. The design of the clamping member ensures the stable fixation of the shock wave test piece during the test.
[0037] In this embodiment, a locking member 5 is provided between the base 2 and the sliding column 11 to lock the base 2 at any position on the column 11, facilitating the adjustment of the distance between the base 2 and the upper second support member 13 to adapt to shock wave test pieces of different lengths. The design of the locking member 5 between the base 2 and the column 11 ensures the stability of the base 2 on the column 11 and provides a stable reference for the movement of the sliding block 3.
[0038] At the same time, the base 2 and the column 11 are designed to be detachably connected. The column 11 is detachably configured with a number of bases 2 having placement cavities 21 of different specifications. The placement cavities 21 provided on the base 2 are adapted to the clamping ends of the shock wave test pieces. The detachable connection design of the base 2 and the column 11, combined with the placement cavities 21 of different specifications, enables the detection member 4 to adapt to shock wave test pieces of various sizes.
[0039] In this embodiment, the detection member 4 is set as a displacement sensor. The sliding block 3 has a cylindrical structure, and a bottom surface 31 is provided at the bottom of the sliding block 3. The bottom surface 31 is used to cooperate with the displacement measurement of the displacement sensor. The provision of the bottom surface 31 at the bottom increases the stability when contacting the displacement sensor. The detection member 4 uses a high-precision displacement sensor, ensuring the accuracy of the measurement results and improving the detection accuracy. The displacement sensor can be a laser displacement sensor or a photoelectric displacement sensor, and the displacement sensor includes but is not limited to the displacement sensors mentioned in this embodiment.
[0040] The sliding block 3 can be a weight with mass. According to the needs of different shock wave tests, weights of different masses are selected. It should be noted that the selection of the weight mass is related to the energy of the shock wave generated. Within the set shock wave generating capacity, the mass of the weight should not be too heavy or too light. When the mass of the weight is too heavy, the shock wave emitted by the shock wave test piece may not be able to push the weight upward or the upward movement distance is too small, resulting in a large measurement error. When the mass of the weight is too light, the shock wave emitted by the shock wave test piece may push the weight to an excessive height, even exceeding the maximum length of the movable space interval, resulting in a measurement failure. Therefore, the selection of the weight mass can be set flexibly and reasonably according to actual needs.
[0041] In this embodiment, for the detection of shock wave energy density, a controller is also provided. The control signal of the controller is connected to the displacement sensor and the computer. The controller is used to send the distance that the slider 3 moves to the computer in real time according to the test data of the displacement sensor. The computer calculates the energy density of the shock wave emitted by the test piece of the shock wave to be measured through the measured distance that the slider 3 moves.
[0042] The divergent shock wave energy density detection device provided in this embodiment is mainly used to measure the shock wave energy density of the treatment handle 8 of the pneumatic ballistic shock wave therapy instrument. However, the shock wave test piece tested by this divergent shock wave energy density detection device is not limited to the treatment handle 8, and can also be used for other devices that need to measure the shock wave energy density.
[0043] When the divergent shock wave energy density detection device works, first place the treatment handle 8 to be tested in the placement cavity 21 of the base 2, and use the clamping block 6 to clamp and fix the handle end 81 of the treatment handle 8 on the base 2. Place a slider 3 with an appropriate mass in the moving space formed by the enclosure of the rod member 14. The treatment head 82 of the treatment handle 8 is correspondingly arranged at the bottom of the moving space, and the slider 3 is slid to the upper end of the treatment head 82 of the treatment handle 8. Start the treatment handle 8, the impact force of the bullet acts on the center of gravity of the slider 3, and the slider 3 starts to move upward. The displacement sensor measures the moving distance that the slider 3 moves upward and sends it to the computer through the controller. The computer calculates the energy density of the shock wave emitted by the treatment handle 8 through this moving distance.
[0044] As mentioned above, the above is only a preferred specific embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention who makes non-substantive changes to the present invention using this concept shall fall within the scope of infringement of the protection of the present invention.
