Description

Technical Field

[0001] This utility model relates to the field of ultrasonic performance testing technology, specifically to a testing device for ultrasonic transducers. Background Technology

[0002] Ultrasound is a high-frequency mechanical wave characterized by its focusability, tissue penetration, and energy deposition. Ultrasound therapy equipment utilizes a focused ultrasound transducer to focus ultrasound waves onto a living organism. The interaction between the ultrasound waves and biological tissue generates thermal, cavitation, and mechanical effects, thus exerting corresponding biological effects. Ultrasound therapy equipment includes an ultrasound treatment handpiece and a treatment head, with the ultrasound transducer installed in the treatment head. In terms of penetration effectiveness, ultrasound > radiofrequency > intense pulsed light / laser. The risks of focused ultrasound technology mainly stem from the temperature and depth of application. Subcutaneous tissue has a dense distribution of nerves, and improper control can easily cause damage to facial nerves or muscles. The depth of application refers to the depth to which the focused energy point of the ultrasound transducer penetrates the subcutaneous tissue.

[0003] Because the focused energy point of each batch of ultrasonic transducers may have process differences, the focused energy point of the ultrasonic transducer needs to be tested and found before the treatment head is assembled. This allows for adjustment of the distance (i.e., focused height) between the ultrasonic transducer and the emission port of the treatment head to ensure that the depth of action is consistent with the required value and to avoid safety accidents caused by improper control of the depth of action.

[0004] The existing testing method involves mounting an ultrasonic transducer onto a treatment head, then using the treatment head to emit ultrasonic waves at a test plate. By observing the burning effect on the test plate surface, the distance between the transducer and the test plate is repeatedly adjusted to find the focal energy point. This testing method requires repeatedly removing and installing the ultrasonic transducer on the treatment head, which is relatively cumbersome and inefficient. Utility Model Content

[0033] like Figures 1 to 5 As shown, the ultrasonic transducer testing device of this embodiment includes a housing 10, a guide 20, a movable seat 30, a mounting seat 40, and a test plate 50.

[0034] The guide member 20 is mounted on the housing 10, and the movable seat 30 is sleeved on the guide member 20 and can reciprocate along the length of the guide member 20.

[0035] The movable base 30 is provided with a slot 31, and the mounting base 40 is detachably inserted into the slot 31;

[0036] Mounting base 40 is used to mount ultrasonic transducer 90, and the ultrasonic emission direction of ultrasonic transducer 90 is consistent with the length direction of guide member 20.

[0037] The chamber 10 is filled with ultrasonic conductive fluid, and a diaphragm 11 is provided on one side of the chamber 10. The plane of the diaphragm 11 is perpendicular to the ultrasonic emission direction of the ultrasonic transducer 90.

[0038] The test plate 50 is movably disposed on the outside of the housing 10 and is in close contact with the diaphragm 11.

[0039] The ultrasonic transducer testing device, through the combination of housing 10, guide 20, movable seat 30, mounting base 40, and test plate 50, achieves stable installation and accurate testing of ultrasonic transducer 90. Guide 20 provides a stable movement path for movable seat 30, ensuring that ultrasonic transducer 90 can move in a predetermined direction, facilitating adjustment of the distance between ultrasonic transducer 90 and test plate 50. Mounting base 40 is connected to movable seat 30 through slot 31, facilitating quick installation and replacement of ultrasonic transducer 90 and improving testing efficiency.

[0040] The method of using this testing device includes the following steps:

[0041] S1.

[0042] S2, Dot test: Focused ultrasonic waves are emitted through the ultrasonic transducer 90, and the test plate 50 is moved to perform multiple dots.

[0043] S3. Judge the test results: Observe the burn points on the test plate 50 and judge whether the burn points meet the characteristics of the focused energy point. If they do not meet the characteristics, adjust the position of the moving seat 30 on the guide 20 and perform the dotting test in step S2 again until the burn points meet the characteristics of the focused energy point. At this time, the position of the moving seat 30 on the guide 20 can be used to obtain the focused height dimension.

[0044] S4. End Test: After obtaining the focus height dimension, the test is considered complete and the test is stopped.

[0045] This device can test and locate the focused energy point of the ultrasound transducer under test, and obtain the focused height dimension. It can provide a dimensional reference when assembling the treatment head, thereby ensuring the effective depth of the focused energy point of the ultrasound transducer and avoiding safety issues.

[0046] In this embodiment, the mounting base 40 includes a base body 41, a clamping block 42, a connecting rod 43, and an elastic element 44. The connecting rod 43 passes through the clamping block 42 and the base body 41, with one end abutting against the outer side of the clamping block 42. The elastic element 44 is sleeved on the other end of the connecting rod 43 and abuts against the base body 41 and the connecting rod 43. Specifically, the clamping block 42 provides clamping force through the elastic element 44, which can adapt to ultrasonic transducers 90 of different sizes, ensuring their stable fixation during testing and avoiding loosening due to vibration or external force. The connecting rod 43 passes through the clamping block 42 and the base body 41, providing a stable connection and support, while facilitating the installation and adjustment of the elastic element 44. This structure allows the mounting base 40 to quickly adapt to different models of ultrasonic transducers 90, improving the versatility and applicability of the testing device. Two connecting rods 43 and two elastic elements 44 are provided to further improve stability.

[0047] In this embodiment, the elastic element 44 is a spring, and the seat body 41 is provided with a receiving groove in which the spring is disposed. Specifically, the selection of a spring as the elastic element 44 can provide a stable elastic clamping force, ensuring that the ultrasonic transducer 90 remains fixed during testing; the design of the receiving groove provides a stable installation space for the spring, preventing displacement or deformation of the spring during use, extending the service life of the spring, and improving the reliability of the mounting seat 40.

[0048] In this embodiment, the base body 41 is provided with a first limiting part 411, and the clamping block 42 is provided with a second limiting part 421. The ultrasonic transducer 90 is clamped between the first limiting part 411 and the second limiting part 421.

[0051] In this embodiment, multiple distance adjustment blocks 60 are also included, and the distance adjustment blocks 60 are detachably connected to the guide member 20. Specifically, the distance adjustment blocks 60 can be made into blocks with standard thickness dimensions. During testing, the moving seat 30 abuts against the distance adjustment blocks 60. By setting multiple distance adjustment blocks 60, the scalability of the testing device is realized, allowing users to adjust the distance between the ultrasonic transducer 90 and the test plate 50 according to testing needs. This enables more accurate evaluation of the performance of the ultrasonic transducer 90 at different working distances and facilitates fine-tuning based on the standard distance when testing the focused energy point.

[0052] In this embodiment, the guide member 20 is a guide rod, which is located between the two side walls of the housing 10. Specifically, two guide rods are preferably provided, arranged at intervals. The guide rods provide stable support and a precise movement path for the movable seat 30, ensuring that the ultrasonic transducer 90 maintains linear motion during movement, thus improving the accuracy of the test. The guide rods being located between the two side walls of the housing 10 makes the entire testing device more compact, saves space, and facilitates operation and maintenance.

[0053] In this embodiment, the test plate 50 is an acrylic plate. Specifically, by observing the burning point of the ultrasonic waves output by the ultrasonic transducer 90 hitting the acrylic plate, it is determined whether the burning point conforms to the characteristics of a focused energy point, which facilitates observation.
