Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a testing device for a shock wave therapeutic apparatus. Background Art

[0002] Medical devices refer to instruments, equipment and appliances that are used directly or indirectly on the human body. They are mainly obtained through physical means and are mainly used for the diagnosis, prevention, monitoring, treatment or relief of diseases.

[0003] Extracorporeal shock wave therapy is a method of treating biological tissues through the mechanical effects and cavitation effects of shock waves in shock wave therapy devices. Because of its advantages of being non-invasive, easy to intervene, and targeted and precise, it is widely used in fields such as extracorporeal lithotripsy, orthopedics, and sports rehabilitation. It has significant therapeutic effects on the treatment of musculoskeletal system and soft tissue diseases such as plantar fasciitis and tendinitis. When used for treatment, the shock waves generated in vitro propagate in the body, and their vibration energy is continuously absorbed by the tissue, causing the physical properties of the medium such as pressure, temperature, and density to change in a leap-like manner. The shock wave energy will be loaded onto the treatment target, producing a therapeutic effect. Therefore, accurately measuring the energy density and energy stability of the shock waves generated by the shock wave therapy device is a key issue in testing the performance of the equipment and evaluating the treatment effect.

[0004] The existing shock wave energy density detection equipment mainly uses a ruler to measure the flying height of the mass block. During the measurement, it is difficult to accurately read the height data due to the high speed of the mass block, resulting in deviations in the energy density measurement results. At the same time, the existing handle fixing method has an uneven tail of the handle, so the handle is skewed and offset during the measurement process, resulting in large errors.

[0005] Therefore, how to ensure that the shock wave handle remains vertical during the measurement process to improve the detection accuracy is a technical problem that technical personnel in this field currently need to solve. Utility Model Content

[0037] The purpose of the utility model is to provide a testing device for a shock wave therapy apparatus, which can ensure that the shock wave handle 400 remains vertical during the measurement process to improve the detection accuracy.

[0038] Please refer to FIG. 1 . To achieve the above-mentioned purpose, the utility model provides a testing device for a shock wave therapy device, including a frame, a shock wave handle 400 and a level.

[0039] The frame body includes an upper platform 300 and a lower platform 200 which are movably arranged at the top and bottom of the support frame. The top and bottom of the upper platform 300 are respectively provided with a guide tube 320 and a three-jaw chuck 310. The guide tube 320 is a hollow structure, and a starting mark and a sensor 321 at the same height are provided on the outside; the lower platform 200 is provided with a lifting platform 210 which can be extended and retracted in the height direction.

[0040] The shock wave handle 400 is vertically attached to the upper surface of the lifting platform 210 through the handle tooling 410. The shock wave handle 400 driven by the lifting platform 210 can drive the spherical mass block 500 to move to the starting mark, and the three-jaw chuck 310 can fix the moved shock wave handle 400.

[0041] The level meter can detect and adjust the lower platform 200 and the upper platform 300 to keep them level.

[0042] The lower platform 200 and the upper platform 300 are adjusted to a horizontal state by using a spirit level, and the shock wave handle 400 connected to the handle tooling 410 is placed vertically on the upper surface of the lifting platform 210. The shock wave handle 400 is driven to move vertically by the lifting platform 210, thereby driving the spherical mass block 500 to move to the starting mark of the guide tube 320. Then, the shock wave therapy device is started to hit the spherical mass block 500 once at maximum output energy. The sensor 321 can obtain the time when the spherical mass block 500 passes through the sensor 321 when it falls, and can accurately measure the shock wave energy density and energy stability generated by the shock wave therapy device. The shock wave handle 400 is kept vertical during the measurement process by using the spirit level and the handle tooling 410 to improve the detection accuracy.

[0043] Preferably, the guide tube 320 is fixedly connected to the upper platform 300 through a fixing block 322, and an interception device 323 is provided at one end of the guide tube 320 away from the upper platform 300 to prevent the spherical mass block 500 from detaching when moving axially along the guide tube 320; the inner wall diameter of the guide tube 320 is larger than the diameter of the spherical mass block 500, and the inner wall of the guide tube 320 is coated with lubricating liquid; the guide tube 320 is made of transparent material.

[0044] During the test, the spherical mass block 500 is placed in the guide tube 320. Preferably, the mass of the spherical mass block 500 is 95g and the diameter is 28mm. The inner diameter of the guide tube 320 is slightly larger than the diameter of the spherical mass block 500. The contact surfaces of the two are coated with lubricating liquid to reduce the friction of the spherical mass block 500 during flight. An interception device 323 is provided at the top of the guide tube 320 to prevent the spherical mass block 500 from flying out during the test. The guide tube 320 is preferably a transparent round tube.

[0045] Preferably, the testing device also includes a processing system 600, which includes an information receiving module, a computing module and a storage module. The information receiving module establishes communication with the sensor 321 and obtains the detection information of the sensor 321; the computing module can import the detection information and calculate the corresponding results; the storage module can display and store the results.

[0046] The sensor 321 is preferably a photoelectric sensor. Before the energy density test of the shock wave therapy device, the processing system 600 is turned on so that the information receiving module and the sensor 321 can establish communication. The treatment head of the shock wave handle 400 is preferably located at one end away from the lifting platform 210, and the surface of the treatment head can be in full contact with the spherical mass block 500. The lower platform 200 and the upper platform 300 are kept in a horizontal state after adjustment by the level meter. The shock wave handle 400 vertically attached to the upper surface of the lifting platform 210 can always be kept in a vertical state through the handle tooling 410, so as to avoid the shock wave handle 400 being skewed due to vibration during the test. By adjusting the height of the lifting platform 210, the center of the spherical mass block 500 is located at the starting mark of the guide tube 320, and then the moved shock wave handle 400 is fixed by the three-jaw chuck 310, so that the shock wave handle 400 and its treatment head and the spherical mass block 500 are on the same axis, which can avoid the treatment head and the spherical mass block 500 not being in full contact during the test, resulting in the spherical mass block 500 flying crookedly and touching the inner wall of the guide tube 320, resulting in inaccurate height data.

[0047] At this time, after the test device is fixed, the output pressure of the shock wave therapy device is set to the maximum, and the striking mode is a single strike. After the strike, the spherical mass block 500 flies vertically in the guide tube 320. After reaching the highest point, it performs free fall motion and returns to the origin. The principle of the test device to detect the flight height is: the spherical mass block 500 performs free fall motion from the highest point and passes through the sensor 321 when returning to the origin. The diameter d of the spherical mass block 500 is known, and the time t1 of passing the sensor can be measured, then the terminal velocity V can be calculated by formula (1).

[0048] ; (1)

[0049] Based on the terminal velocity V obtained above, the movement time t2 of the spherical mass block 500 from the highest point to the detection point can be calculated according to formula (2), where g in formula (2) is the gravitational acceleration.

[0050] ; (2)

[0051] Based on the above-mentioned movement time t2 from the highest point to the detection point, the distance h in the height direction from the highest point of the movement of the spherical mass block 500 to the detection point can be calculated according to formula (3).

[0052] ; (3)

[0053] The above calculation process is automatically completed by the calculation module of the processing system 600, and the height data h is directly displayed. Hit 10 times and record the height data. The processing system 600 calculates the output energy of the shock wave handle 400 based on the above data using formula (4), and takes the average value to obtain the maximum output energy of the measured device. Repeat once every 20 minutes, repeat 5 times in total, calculate the average value of the 5 data, and calculate the error. The error value should be within the standard range, where E in formula (4) is the output energy; m is the mass of the spherical mass block 500.

[0054] ; (4)

[0055] Based on the above output energy E, the diameter of the treatment head is measured using a universal measuring tool, the area of ​​the treatment head is calculated, and the energy density is calculated using formula (5), where ED is the energy density and S is the area of ​​the treatment head.

[0056] ; (5)

[0057] The storage module can display and store the final results.

[0058] It should be noted that, in this embodiment, the speed of the spherical mass block 500 passing the detection point is detected to calculate the distance between the detection point and the highest point of the movement of the spherical mass block 500. When the detection point and the origin (the same as the center height of the spherical mass block 500 before being hit) are set at different heights, the distance from the origin to the highest point of the spherical mass block 500 should be the sum of the distances between the detection point and the highest point and between the origin and the detection point. After inputting the corresponding data, the calculation module can recalculate the distance.

[0059] Preferably, the support frame includes a plurality of vertically extending columns 100, and the bottoms of all the columns 100 are rotatably connected with horizontal hoof feet 110 to adjust the height of the corresponding columns 100. The lower platform 200 and the upper platform 300 are both mounted on all the columns 100, and all the columns 100 are provided with threads. The horizontal hoof feet 110 are threadedly connected to the columns 100, and first connecting members are respectively provided on both sides of the lower platform 200 to fix the lower platform 200 adjusted to the horizontal state, and second connecting members 330 are respectively provided on both sides of the upper platform 300, and the second connecting members 330 are threadedly connected to the columns 100 to fix the upper platform 300 adjusted to the horizontal state relative to the columns 100.

[0060] It can be understood that the support frame in this embodiment includes a plurality of vertically extending columns 100, and the height of the lowest end of the corresponding column 100 can be adjusted by rotating the horizontal hoof feet 110 at the bottom thereof. The lower platform 200 and the upper platform 300 are both mounted on all the columns 100, and first connecting members are respectively provided on both sides of the lower platform 200. The first connecting members are threadedly connected to the columns 100 to fix the adjusted lower platform 200 so that the lower platform 200 remains horizontal. Second connecting members 330 that can be threadedly connected to the columns 100 are respectively provided on both sides of the upper platform 300, so that the upper platform 300 adjusted to a horizontal state is fixed relative to the columns 100.

[0061] Preferably, the upper end surface of the lifting platform 210 is parallel to the lower platform 200, the handle tooling 410 embraces one end of the shock wave handle 400 close to the upper end surface, and the bottom of the handle tooling 410 is provided with a bottom surface that can fit the upper end surface, so that the shock wave handle 400 is perpendicular to the lower platform 200.

[0062] In this embodiment, the lifting platform 210 includes two end faces parallel to the lower platform 200. One of the end faces is fitted with the lower platform 200, so that the other end face is parallel to the lower platform 200 and is used to fit with the bottom of the handle tooling 410, so that the shock wave handle 400 is perpendicular to the end face and the lower platform 200. The lifting platform 210 can be lifted and lowered to drive the shock wave handle 400 to move vertically.

[0063] Preferably, the three-jaw chuck 310 is connected to a rotating handle 311 , and the rotating handle 311 can control the three-jaw chuck 310 to move closer to or away from the axial direction of the guide tube 320 to clamp or release the shock wave handle 400 coaxially arranged with the guide tube 320 .

[0064] It should be noted that, preferably, a through hole is provided in the middle of the three-jaw chuck 310 for the shock wave handle 400 to pass through, and the three-jaw chuck 310 is connected to a rotating handle 311. By rotating the rotating handle 311, the three-jaw chuck 310 can be contracted toward the middle to clamp the shock wave handle 400 therein, thereby limiting the rotation and movement of the shock wave handle 400. When the test is completed, the rotating handle 311 is twisted in the opposite direction to allow the three-jaw chuck 310 to loosen the shock wave handle 400.

[0065] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the utility model.
