Description
Technical Field
[0001] The utility model relates to a test device for detecting the penetration depth of extracorporeal shock wave energy, in particular to a shock wave energy penetration depth detection device. Background Art
[0002] Shock wave therapy is a non-invasive treatment method widely used in the treatment of musculoskeletal diseases. The penetration depth of shock wave energy is one of the key factors affecting the treatment effect. If the penetration depth 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 penetration depth of the shock wave energy of the extracorporeal shock wave equipment meets the standard.
[0003] When the current detection equipment measures the extracorporeal shock penetration depth, it mainly relies on a ruler to measure the vertical distance from the treatment head to the piezoelectric sensor under one or two simulated loads. Then, the voltage signal is measured by an oscilloscope and converted into a pressure value, and then the penetration depth is calculated through a formula. When a mass block is added to the upper end of the treatment head of the extracorporeal shock wave and pressed on the rubber pad, the rubber pad will deform. At this time, there will be an error when using a ruler to measure the distance from the treatment head to the piezoelectric sensor under the rubber pad, because the treatment head is indented in the rubber pad and cannot be visually measured, which will have a certain impact on the evaluation of the treatment effect of the pneumatic ballistic extracorporeal pressure wave treatment equipment. Summary of the Utility Model

This fixture assembly 3 is used to clamp and fix a shock wave therapy gun 5, and a locking member 6 is provided between the fixture assembly 3 and the fixing frame 2 for locking the fixture assembly 3 at any position on the fixing frame 2. Through the locking member 6, the position of the fixture assembly 3 on the fixing frame 2 can be precisely adjusted to ensure that the treatment head can stably abut against the end face of the rubber pad 8, avoiding errors caused by the deformation of the rubber pad 8.
[0039] The specific structure of this fixture assembly 3 includes a sliding member, a first clamping block 31, and a second clamping block 32. On both sides of the fixing frame 2 at opposite positions corresponding to the sliding member, first sliding rails are provided to ensure the stable sliding of the sliding member on the fixing frame 2. The sliding member is sequentially provided with a first slider 34 and a second slider 35 on both sides. The sliders are in sliding fit with the sliding rails. One or both of the first slider 34 and the second slider 35 are set as tightening sliders, and a locking rod is connected to the tightening slider to form a locking member.

A groove 33 is provided on the side of the second clamping block 32 opposite to the first clamping block 31, and this groove 33 is used to place the gun barrel 51 of the therapy gun 5.
[0040] A detection unit 7 is provided on the support platform 1.

And an automated data processing system is adopted. Combining the measurement data of the digital caliper 9 and the signals collected by the pressure sensor, the penetration depth is accurately calculated through a built-in algorithm, reducing human calculation errors.
[0045] The position of the fixture assembly 3 can be dynamically adjusted according to the measurement results of the digital caliper 9 and the test data of the shock wave energy to ensure that the best contact state is always maintained between the treatment head and the rubber pad 8.

[0049] Step 3, adjust the position of the detection unit 7 and the treatment head of the treatment gun 5; place a rubber pad 8 on the pressure sensor, and adjust the height of the treatment gun 5 through the sliding member so that the treatment head of the treatment gun 5 can accurately abut against the end face of the rubber pad 8 without causing extrusion deformation to the rubber pad 8.
[0050] Step 4: Start the treatment gun 5 to strike the shock wave ability of the rubber pad 8, obtain the data of the generated voltage value through the pressure sensor, and calculate the value a1 of the shock wave energy through the automated data processing system.
[0051] Step 5: Turn off the treatment gun 5 and perform the second stacking of the rubber pad 8; stack another rubber pad 8 on the pressure sensor, and adjust the height of the treatment gun 5 again through the sliding member so that the treatment head of the treatment gun 5 abuts against the end face of the second rubber pad 8.
