The shock wave device is a pneumatic ballistic extracorporeal pressure wave therapy device based on shock wave therapy.
[0003] Pneumatic ballistic extracorporeal pressure wave therapy equipment uses the energy generated by compressed air to drive the bullet body in the cavity of the control handle, so that the bullet body pulses and impacts the treatment head, and uses the elastic collision of the two to generate pressure waves, which are conducted through the skin to treat the painful area. Pneumatic ballistic extracorporeal pressure wave therapy equipment usually includes a host, a control handle, a bullet body set in the cavity of the control handle, a treatment head and an air compressor contained in the host.

The spacing between the first support splint 1 and the second support splint 2 is adjustable and connected by two screws 6. The first support splint 1 is provided with a first through hole 7 which is directly opposite to the treatment head 23 in the upper and lower parts. The upper surface of the first support splint 1 is detachably mounted with a first clamping tool for clamping and fixing the transparent test tube 3. The first clamping tool corresponds to the first through hole 7 in the upper and lower parts so that the transparent test tube 3 can be clamped. The lower end of the transparent test tube 3 is butted with the upper end of the first through hole 7. The transparent test tube 3 is used to guide the mass block and observe the flying height of the mass block during energy stability detection. The upper surface of the second support splint 2 is detachably mounted with a second clamping tool for clamping and fixing the control handle 22. The pressure sensor 5 is detachably mounted on the lower surface of the first support splint 1 and corresponds to the upper and lower sides of the treatment head 23. The rubber pad 4 is pressed between the pressure sensor 5 and the treatment head 23 and used as a simulated load during penetration depth detection. The static load pressure component is placed on the upper part of the second support splint 2 after the detection tool is reversed 180° to apply static force to the control handle 22 during penetration depth detection. The pressure sensor 5 is a piezoelectric sensor or a piezoresistive sensor. The signal output end is connected to an oscilloscope or directly connected to a high-speed impact force acquisition instrument to directly read the instantaneous maximum pressure value.
[0033] The first supporting plate 1 and the second supporting plate 2 are correspondingly provided with light holes for installing the screw 6. The upper end of the screw 6 is provided with a nut 8 tightly pressed against the upper surface of the first supporting plate 1, and the lower side of the screw 6 is threadedly installed with a nut 9 tightly pressed against the lower surface of the second supporting plate 2.

[0035] The working principle of this embodiment is as follows: According to the test method in Chapter 6 of the industry standard "YY / T 0950-2015 Pneumatic Ballistic Extracorporeal Pressure Wave Therapy Equipment":

At the same time, the pressure sensor 5 is removed from the lower surface of the first support splint 1. The testing tool is placed normally so that the two support feet 10 on the lower surface of the second support splint 2 are fixedly supported on an experimental platform. The lower ends of the two screws 6 pass through the experimental platform. There is a certain distance between the first support splint 1 and the treatment head 23. Then, the first support splint 1 is slowly moved downward, and the two screws 6 are synchronously moved downward through the two light holes on the second support splint 2 until the lower surface of the first support splint 1 is pressed on the upper end of the cavity of the control handle 22, and the treatment head 23 is correspondingly inserted into the first through hole 7. At this time, the first support splint 1 and the second support splint 2 are The clamping plate 2 clamps the upper and lower ends of the control handle 22, tightens the nut 9, and makes the nut 9 press against the lower surface of the second supporting clamping plate 2. Then, the mass block is placed in the transparent test tube 3 and falls on the treatment head 23. The host of the shock wave using device is started, and the energy generated by the compressed air drives the bullet body in the cavity of the control handle 22, so that the bullet body pulses and impacts the treatment head 23. The elastic collision of the two generates a pressure wave. The treatment head 23 applies the pressure wave to the mass block, and the mass block flies upward, so that the pressure wave energy output by the shock wave using device is converted into the gravitational potential energy of the mass block. The flying height of the mass block is observed and recorded through the transparent test tube 3. Here, a high-speed camera or an industrial camera can be set on one side of the transparent test tube 3 to shoot and record the flying height of the mass block. The transparent test tube 3 has a scale, and the flying height of the mass block is read by the scale value.

Then, the second supporting splint 2 is slowly moved downward so that the treatment head 23 is pressed on the rubber pad 4, and the nut 9 is tightened so that the nut 9 is pressed tightly against the upper surface of the second supporting splint 2 at this time, and then the static load pressure component is placed on the upper part of the second supporting splint 2 to apply static force to the control handle 22, and the main unit of the shock wave device is started, so that the shock wave device releases a pressure wave at a single time at the maximum output energy, records the pressure, and measures the vertical distance from the treatment head 23 to the pressure sensor 5, and changes the thickness of the rubber pad 4. Repeat the process of releasing the pressure wave at a single time at the maximum output energy of the shock wave device, records the pressure, and measures the vertical distance from the treatment head 23 to the pressure sensor 5, and calculate the penetration depth of the shock wave device according to the penetration depth formula in the industry standard "YY / T 0950-2015 Pneumatic Ballistic Extracorporeal Pressure Wave Therapy Device".
