Description

Technical Field

[0001] This utility model relates to the field of ultrasonic therapy instrument technology, and in particular to a porous test fixture for calibrating the sound field of an ultrasonic therapy instrument. Background Technology

[0002] An ultrasound therapy device is a medical device that utilizes the physical properties of ultrasound waves, such as mechanical vibration, thermal effects, and cavitation effects, to focus ultrasound energy onto the affected area of ​​the human body through a specific probe, thereby treating diseases, relieving symptoms, or promoting rehabilitation. A porous test fixture used to calibrate the sound field of an ultrasound therapy device is a specially designed auxiliary device. Through its porous structure, it interacts with the sound field of the ultrasound therapy device. Based on the physical phenomena of reflection, refraction, and scattering that occur when ultrasound waves propagate in a porous medium, it calibrates the sound field of the ultrasound therapy device to ensure that the sound field output by the ultrasound therapy device meets predetermined treatment requirements and safety standards.

[0003] Traditional multi-hole test fixtures for calibrating the sound field of ultrasonic therapy instruments have fixed hole positions, making it inconvenient to adapt the hole spacing. They can only cover a specific sound field area and are difficult to adapt to the sound field range of different models of ultrasonic therapy instruments.

[0004] Therefore, a porous test fixture for calibrating the sound field of an ultrasound therapy device is needed to solve the above problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the aforementioned problem with a porous test fixture for calibrating the sound field of an ultrasonic therapy instrument, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a multi-hole test fixture for calibrating the sound field of an ultrasonic therapy instrument, which solves the problem that "the holes of traditional multi-hole test fixtures for calibrating the sound field of ultrasonic therapy instruments are mostly arranged in a fixed manner, which makes it inconvenient to adapt the hole spacing to the desired effect, and can only cover a specific sound field area, making it difficult to adapt to the sound field range of different models of ultrasonic therapy instruments".

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a porous test fixture for calibrating the sound field of an ultrasonic therapy instrument, comprising:

[0009] A clamp support, wherein a perforated plate is fixedly installed at the end of the clamp support, and an annular hole is sleeved inside the perforated plate;

[0010] An adjustment unit is located outside the annular hole. The adjustment unit includes opposing threaded rods, a first connecting block, a connecting plate, and a second connecting block, and is used to adjust the equal distance between the hole plate and the annular hole.

[0011] The disassembly and assembly unit is located on the side of the orifice plate. The disassembly and assembly unit includes a clamping plate for quick disassembly and replacement of the annular holes and the orifice plate after long-term use. Under the constraint of the fixture bracket, it is connected to the multi-hole test fixture. The ultrasonic therapy instrument is calibrated by the cooperation between the orifice plate and the annular holes. The spacing between the annular holes can be adjusted equidistantly by the adjustment unit to adapt to different models of ultrasonic therapy instruments. Under the constraint of the disassembly and assembly unit, the annular holes that have been used for a long time can be disassembled and replaced to ensure that the ultrasonic therapy instrument can be accurately calibrated.

[0012] As a preferred embodiment of the multi-hole test fixture for calibrating the sound field of an ultrasonic therapy instrument according to the present invention, the adjustment unit includes a sleeve block fixedly installed on the top surface of the orifice plate, a counter-threaded rod sleeved inside the sleeve block, a fixing plate rotatably connected to the outer wall of the counter-threaded rod, a sealing plate slidably disposed inside the orifice plate, and a slider slidably disposed inside the sealing plate.

[0013] As a preferred embodiment of the multi-hole test fixture for calibrating the sound field of an ultrasonic therapy instrument according to the present invention, wherein: a first connecting block is fixedly installed at the bottom of the annular hole, a connecting plate is hinged inside the first connecting block, a second connecting block is hinged at the end of the connecting plate away from the first connecting block, and a spring is fixedly installed on the side wall of the second connecting block.

[0014] As a preferred embodiment of the multi-hole test fixture for calibrating the sound field of an ultrasonic therapy instrument according to the present invention, wherein: a slide rod is slidably arranged inside the second connecting block, and a fixing block is fixedly installed at the end of the slide rod.

[0015] As a preferred embodiment of the multi-hole test fixture for calibrating the sound field of an ultrasonic therapy instrument according to this utility model, the outer wall of the slider is fixedly installed inside the orifice plate, and the outer wall of the sealing plate is slidably disposed inside the orifice plate. Under the restriction of the slider, the sealing plate is always slidable inside the orifice plate. Under the restriction of the sealing plate, it can be ensured that the sound waves of the ultrasonic therapy instrument enter the annular hole.

[0016] As a preferred embodiment of the multi-hole test fixture for calibrating the sound field of an ultrasonic therapy instrument according to the present invention, the disassembly and assembly unit includes a vertical plate fixedly installed on the outer wall of the perforated plate, a limiting rod fixedly installed on the side wall of the vertical plate, a sliding sleeve slidably provided on the outer wall of the limiting rod, and a clamping plate fixedly installed on the side wall of the sliding sleeve.

[0017] As a preferred embodiment of the multi-hole test fixture for calibrating the sound field of an ultrasonic therapy instrument according to the present invention, wherein: the end of the clamping plate is provided with an arc surface, and the side wall of the clamping plate is slidably disposed with the end of the annular hole, so that the annular hole can be clamped and restricted inside the perforated plate under the constraint of the clamping plate.

[0018] As a preferred embodiment of the multi-hole test fixture for calibrating the sound field of an ultrasonic therapy instrument described in this utility model, there are two limiting rods, which are symmetrically distributed around the center line of the clamping plate. Under the restriction of the limiting rods, the sliding sleeve drives the clamping plate to slide stably.

[0019] The beneficial effects of this utility model are as follows: When calibrating an ultrasonic therapy instrument, the spacing between the annular holes can be adjusted according to the model. By rotating the opposing threaded rod, the two end plates move in opposite directions under the restriction of the sealing plate. The connecting plate pushes the second connecting block, causing the annular plates to converge at a centered distance. The spring applies the same force to the second connecting block under the restriction of the fixed block, preventing the annular plates from sliding, ensuring accurate equidistant adjustment, adapting to different models of equipment, and improving calibration accuracy.

[0020] When the annular hole needs to be replaced after prolonged use, push the retaining plate upwards to slide it along the end of the annular hole to remove the old annular hole. After inserting the new annular hole, release the retaining plate, and it will slide down under gravity. With the help of the limit rod to stabilize the sliding sleeve, the annular hole and the orifice plate can be quickly replaced, ensuring the accuracy of calibration. Attached Figure Description

[0033] Example 1

[0034] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention, which provides a porous test fixture for calibrating the sound field of an ultrasonic therapy device, comprising:

[0035] A fixture bracket 100 is provided, and a perforated plate 101 is fixedly installed at the end of the fixture bracket 100. An annular hole 102 is provided inside the perforated plate 101.

[0036] Adjustment unit 200 is located outside the annular hole 102. Adjustment unit 200 includes opposing threaded rod 202, first connecting block 206, connecting plate 207 and second connecting block 208, and is used to adjust the spacing between the hole plate 101 and the annular hole 102.

[0037] The disassembly and assembly unit 300 is located on the side of the orifice plate 101. The disassembly and assembly unit 300 includes a retaining plate 304, which is used for quick disassembly and replacement of the annular hole 102 and the orifice plate 101 after long-term use.

[0038] During use, under the constraint of the clamp bracket 100, it is connected to the multi-hole test fixture. Through the cooperation of the orifice plate 101 and the annular hole 102, the ultrasonic therapy instrument is calibrated. The spacing of the annular hole 102 can be adjusted equidistantly by the adjustment unit 200 to adapt to different models of ultrasonic therapy instruments. Under the constraint of the disassembly and assembly unit 300, the annular hole 102 that has been used for a long time can be disassembled and replaced to ensure that the ultrasonic therapy instrument can be accurately calibrated.

[0039] Example 2

[0040] Reference Figure 3 and Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiment, as follows:

[0041] The adjustment unit 200 includes a sleeve block 201 fixedly installed on the top surface of the orifice plate 101. A counter-threaded rod 202 is sleeved inside the sleeve block 201. A fixing plate 203 is rotatably connected to the outer wall of the counter-threaded rod 202. A sealing plate 204 is slidably arranged inside the orifice plate 101. A slider 205 is slidably arranged inside the sealing plate 204. A first connecting block 206 is fixedly installed at the bottom of the annular hole 102. A connecting plate 207 is hinged inside the first connecting block 206. A second connecting block 208 is hinged to the end of the connecting plate 207 away from the first connecting block 206. A spring 209 is fixedly installed on the side wall of the second connecting block 208. A sliding rod 211 is slidably arranged inside the second connecting block 208. A fixing block 210 is fixedly installed at the end of the sliding rod 211.

[0042] The outer wall of the slider 205 is fixedly installed inside the perforated plate 101, and the outer wall of the sealing plate 204 is slidably set inside the perforated plate 101. Under the restriction of the slider 205, the sealing plate 204 is always slidable inside the perforated plate 101. Under the restriction of the sealing plate 204, it can be ensured that the sound waves of the ultrasonic therapy device enter the interior of the annular hole 102.

[0043] During use, when calibrating the ultrasonic therapy device, the spacing of the annular holes 102 is adjusted adaptively according to its model. At this time, rotating the opposing threaded rod 202 causes the two ends of the annular plates 101 to move in opposite directions due to the sliding sealing plate 204 inside the annular plate 101. The annular plates 101 drive the first connecting block 206 fixedly mounted at their bottom to move. Under the constraint of the fixing plate 203, the middle annular plate 101 remains stationary. At this time, the first connecting block 206 pushes the second connecting block 208 through the connecting plate 207, in the hinge mechanism... Under the constraint, the perforated plate 101 can be centered and equidistantly converged. Since the fixing block 210 is fixedly installed at the bottom of the sealing plate 204, under its constraint, the spring 209 pushes the second connecting block 208. The second connecting block 208 slides on the outer wall of the slide rod 211. Under the elastic action, the same force is applied to each second connecting block 208, preventing the perforated plate 101 from sliding arbitrarily, so as to ensure the precise equidistant adjustment of the perforated plate 101. This structure can adjust the annular holes 102 at equal intervals to adapt to different models of ultrasonic therapy instruments, making the calibration more accurate.

[0044] Example 3

[0045] Reference Figure 5 and Figure 6 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiments, as detailed below:

[0046] The disassembly and assembly unit 300 includes a vertical plate 301 fixedly installed on the outer wall of the perforated plate 101. A limit rod 302 is fixedly installed on the side wall of the vertical plate 301. A sliding sleeve 303 is slidably provided on the outer wall of the limit rod 302. A clamping plate 304 is fixedly installed on the side wall of the sliding sleeve 303.

[0047] The end of the clamping plate 304 is arc-shaped, and the side wall of the clamping plate 304 is slidably disposed with the end of the annular hole 102. Under the constraint of the clamping plate 304, the annular hole 102 can be clamped and restricted inside the hole plate 101.

[0048] There are two limiting rods 302, which are symmetrically distributed around the center line of the clamping plate 304. Under the restriction of the limiting rods 302, the sliding sleeve 303 drives the clamping plate 304 to slide stably.

[0049] When using the device, if the annular hole 102 has been used for a long time, it needs to be replaced to avoid affecting the calibration accuracy of the ultrasonic therapy device. At this time, push the clamping plate 304 upward, and slide the clamping plate 304 against the end of the annular hole 102 to remove the annular hole 102 from the inside of the perforated plate 101. Then, put the new annular hole 102 into the inside of the perforated plate 101, release the clamping plate 304, and slide it downward under its own gravity to restrict the annular hole 102 inside the perforated plate 101. Under the restriction of the limiting rod 302, the sliding sleeve 303 and the clamping plate 304 slide stably. This structure can quickly replace the annular hole 102 and the perforated plate 101 to ensure accurate calibration of the ultrasonic therapy device.

[0050] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0051] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
