Description

Technical Field

[0001] This utility model relates to the field of ultrasonic handle testing technology, specifically to an ultrasonic handle temperature monitoring device. Background Technology

[0002] An ultrasonic handpiece, such as an ultrasonic transducer used in medical aesthetic or therapeutic devices, transmits mechanical energy by generating high-frequency vibrations, converting this energy into heat or other forms of energy to act on specific tissue layers in the skin or body. Different frequency and power settings of the ultrasonic handpiece affect the propagation characteristics of ultrasonic energy. By adjusting the device parameters (such as frequency, energy, pulse duration, etc.), it is ensured that the ultrasonic waves accurately reach the target depth while avoiding unnecessary damage to the skin. Therefore, temperature monitoring of the ultrasonic handpiece is a crucial step in ensuring that the device can accurately and safely achieve the expected therapeutic effect during research and development and production.

[0003] To accurately measure the operating temperature of ultrasound, existing technology uses thermochromic gel as the target material for the ultrasonic handpiece. The specific process is as follows: The tester clamps the ultrasonic handpiece with a fixture, immerses it in a medium of water, and aligns the focal point of the handpiece with the thermochromic gel. Then, the ultrasonic handpiece is activated to generate ultrasonic energy, which is transferred through the medium of water to the thermochromic gel, causing it to heat up and change color. The color of the thermochromic gel indicates the operating temperature of the ultrasonic handpiece. However, the temperature range of thermochromic gels is limited, and the operating temperature of the ultrasonic handpiece may change frequently during parameter adjustments. Therefore, a thermochromic gel with a wider temperature range for color change is needed. However, an excessively wide temperature range makes it difficult to accurately determine the actual operating temperature of the ultrasonic handpiece. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an ultrasonic handle temperature monitoring device that can relatively accurately measure the small temperature range of an ultrasonic handle.

[0005] An ultrasonic handpiece temperature monitoring device is provided, comprising an observation tank, wherein a reaction layer, a spacer layer, and an operating layer are arranged from bottom to top within the observation tank. The reaction layer is laterally arranged into multiple test areas, each containing a test gel. The test gel is specifically a thermochromic gel made of a temperature-sensitive material, and the thermochromic gel in each test area undergoes a color change reaction within a different temperature range. The spacer layer contains a water medium. The operating layer is used to house the ultrasonic handpiece, which can move laterally within the operating layer with its ultrasonic emission direction facing the reaction layer, thereby aligning with the test gel in each test area and remaining there for the same working time. If the working temperature of the ultrasonic handpiece falls within the color change reaction temperature range of the test gel in the test area during the working time, the test gel in that test area undergoes a color change reaction. The union of the temperature ranges of all test areas that undergo a color change reaction is taken as the temperature range of the ultrasonic handpiece.

[0006] Furthermore, the temperature at which the test gel in each test area undergoes a color-changing reaction increases sequentially from left to right.

[0007] Furthermore, the temperature ranges at which the test gels in adjacent test areas undergo color-changing reactions partially overlap.

[0008] Furthermore, the observation tank is a visible water tank with at least one transparent side.

[0009] Furthermore, the system includes an imaging device for capturing images of the reaction layer on the transparent side of the visible water tank, the imaging device being used to acquire color images of each test area of ​​the reaction layer before and after the ultrasonic handle is operated; it also includes a processor communicatively connected to the imaging device and a display device communicatively connected to the processor, the processor including a comparison device for comparing whether the color images of each test area have changed before and after the ultrasonic handle is operated, and the display device for displaying the test areas where the color images have changed.

[0010] Furthermore, it includes a scale set on the transparent side of the observation slot.

[0011] Furthermore, the medium water is degassed water.

[0012] Furthermore, the test gel is a reversible thermochromic gel, which returns to its original color after a preset time period of time following the temperature that caused the color change reaction.

[0013] Furthermore, it also includes a mounting bracket for fixing the ultrasonic handle to the top of the observation tank, the ultrasonic handle being mounted on the mounting bracket in a horizontal or vertical manner, with the ultrasonic emission direction of the ultrasonic handle facing the test gel.

[0014] Furthermore, the mounting bracket includes a displacement device for moving the ultrasonic handle laterally.

[0015] Beneficial effects: This ultrasonic handpiece temperature monitoring device includes an observation tank. The reaction layer at the bottom of the observation tank is horizontally arranged into multiple test areas, each containing a test gel. The test gel is specifically a thermochromic gel made of a temperature-sensitive material. The thermochromic gel in each test area undergoes a color change reaction within a different temperature range. After the ultrasonic handpiece is placed in the observation tank and aligned with the test gel in the test area for a preset time, a color change reaction occurs if the operating temperature of the ultrasonic handpiece reaches the sensitive temperature of the test gel in the test area. The union of all test areas that exhibit color changes is taken as the temperature range of the ultrasonic handpiece. When the ultrasonic head of the ultrasonic handpiece operates, the heat generated causes the test gel in adjacent areas to change color. By pre-calibrating the relationship between the color and temperature of the test gel in each area, the operating temperature range of the ultrasonic handpiece can be directly inferred by superimposing the temperature ranges of the color changes in multiple test areas, thus achieving a relatively accurate measurement of the smaller temperature range of the ultrasonic handpiece.

[0019] Figure 3 yes Figure 2 Enlarged view of section A in the middle. Detailed Implementation

[0020] The present invention will be further described in detail below with reference to specific embodiments.

[0021] like Figures 1-3As shown, the ultrasonic handpiece temperature monitoring device of this embodiment includes an observation tank 1. The observation tank 1 has a reaction layer, a spacer layer, and an operation layer arranged from bottom to top. The reaction layer is horizontally arranged into multiple test areas 31, each containing a test gel 3. The test gel 3 is specifically a thermochromic gel made of a temperature-sensitive material. The thermochromic gel in each test area 31 undergoes a color change reaction within different temperature ranges, marking the temperature of the test gel 3 in each test area. The temperature of the test gel 3 undergoing a color change reaction in each test area 31 increases sequentially from left to right, and the temperature ranges of the test gel 3 undergoing a color change reaction in adjacent test areas 31 partially overlap. The operation layer is used to house the ultrasonic handpiece 5. The ultrasonic handpiece 5 can move laterally within the operation layer with the ultrasonic emission direction facing the reaction layer, thereby aligning with the test gel 3 in each test area 31 and remaining there for the same working time. The ultrasonic handpiece is operated sequentially from left to right for a preset time period (e.g., 10 seconds), and the color of the corresponding area changes after the preset time period (e.g., 10 seconds) following the operation of the ultrasonic handpiece. If the working temperature of the ultrasonic handle 5 falls within the color change reaction temperature range of the test gel 3 in the test area during the working time, the test gel 3 in the test area 31 will undergo a color change reaction. The union of the temperature ranges of all test areas 31 that undergo color change reaction is taken as the temperature range of the ultrasonic handle 5.

[0022] In this embodiment, the observation tank 1 is a visible water tank with at least one transparent side. The ultrasonic handle temperature monitoring device also includes an imaging device for capturing images of the reaction layer aligned with the transparent side of the visible water tank. The imaging device is used to acquire color images of each test area 31 of the reaction layer before and after the ultrasonic handle is activated. It also includes a processor communicatively connected to the imaging device and a display device communicatively connected to the processor. The processor includes a comparison device for comparing whether the color images of each test area have changed before and after the ultrasonic handle is activated. The display device is used to display the test areas where the color images have changed. Specifically, the processor is an image analysis system communicatively connected to the imaging device, which is specifically an optical sensor or a camera. The imaging device automatically captures color images of the test gel 3 within a preset time period (e.g., 10 seconds) after the ultrasonic head of the ultrasonic handle is activated. These color images are uploaded to the image analysis system. The image analysis system reads the color of each color image according to a preset color recognition program and outputs the temperature of the ultrasonic handle received by the test gel 3 corresponding to the color image based on a pre-stored color-temperature correspondence, thus achieving real-time temperature monitoring.

[0023] This ultrasonic handpiece temperature monitoring device generates heat when the ultrasonic head of the ultrasonic handpiece is working, which causes the test gel in the adjacent area to change color. By pre-calibrating the relationship between the color and temperature of the test gel in each area, the operating temperature range of the ultrasonic handpiece can be inferred by superimposing the temperature ranges of the color change reactions in multiple test areas, thus achieving a relatively accurate measurement of the small temperature range of the ultrasonic handpiece.

[0024] The test gel in this embodiment is a reversible thermochromic gel. This reversible thermochromic gel returns to its original color after a preset time period following the temperature that caused the color change. During temperature monitoring with the ultrasonic handpiece, the handpiece emits ultrasonic signals to the test gel. These signals undergo reflection and scattering as they penetrate the material being tested. When the ultrasonic signals penetrate the thermochromic gel, the local temperature of the material changes due to the absorption and conversion of sound energy, causing the thermochromic gel within the range of ultrasonic energy to change color. The color of these thermochromic gels changes reversibly with temperature changes, visually displaying the depth of the ultrasonic signal's effect and energy distribution.

[0025] The reversible thermochromic gel in this embodiment is selected based on the different temperature ranges to be monitored, and can be thermochromic liquid crystal (TLC), microencapsulated dyes, or phase change materials (PCMs). Thermochromic liquid crystal (TLC): changes color within a narrow temperature range (e.g., 5°C for each material). Microencapsulated dyes: encapsulate dyes with different transition temperatures in microcapsules to ensure they are sensitive only to a set temperature. Phase change materials (PCMs): undergo a solid-liquid phase transition at a specific temperature, accompanied by a color change. The selected thermochromic material is mixed with a suitable matrix (e.g., silica gel, hydrogel, etc.) to prepare test gels with different temperature response characteristics, ensuring that each test gel exhibits a unique color change within a specified temperature range.

[0026] See Figure 2The ultrasonic handle temperature monitoring device of this embodiment also includes a mounting bracket 6 for fixing the ultrasonic handle 5 above the observation tank. The ultrasonic handle 5 is mounted on the mounting bracket 6 in a horizontal or vertical manner, with the ultrasonic emission direction of the ultrasonic handle 5 facing the test gel 3 downwards. The mounting bracket 6 includes a displacement device (not shown in the figure) for moving the ultrasonic handle horizontally left and right, so that the ultrasonic handle is aligned with each test area 31. During testing, the ultrasonic handle 5 is mounted above the observation tank 1 with the ultrasonic emission direction vertically downwards and aligned with the test gel 3. The mounting bracket 6 includes a slide groove 61 and a slider 62 for fixing the ultrasonic handle 5. The slider 62 is used to move the ultrasonic handle 5 up and down within the slide groove 61 to adjust the working height of the ultrasonic handle 5. The mounting bracket 6 also includes a rotating bracket 63 for clamping the ultrasonic handle 5. The rotating bracket 63 is mounted on the side of the slider 62 in a manner that allows it to rotate around a vertical axis, so as to rotate the ultrasonic handle 5 to the transparent side closer to the observation tank 1, making it easier to observe the color changes of each test area. The ultrasonic handle temperature monitoring device in this embodiment directly observes the changes of different test areas 31 and test gels 3 at different heights under the action of ultrasonic energy through the observation slot 1, thereby identifying the position of the test gel 3 corresponding to the preset ultrasonic energy and realizing the monitoring of the temperature of the ultrasonic handle.

[0027] The working process of the ultrasonic handpiece temperature monitoring device in this embodiment is as follows: The ultrasonic handpiece is installed above the observation tank, ensuring its position is accurate and fixed. A thermochromic gel is placed below the ultrasonic handpiece as a test gel. The ultrasonic handpiece is activated to emit an ultrasonic signal, and the color change of the thermochromic gel is observed. The location and shape of these changes are recorded, and these records are used to analyze the depth of the ultrasonic signal's action and energy distribution. Based on the observed color change, combined with the parameter settings of the ultrasonic equipment (such as frequency and power), the operating temperature of the ultrasonic handpiece is confirmed. This embodiment also includes a scale 4 set on the transparent side of the observation tank, see [link to relevant documentation]. Figure 3 The enlarged view of part A shows the depth of action of the ultrasonic handle recorded by scale 4. By adjusting the parameters of the equipment, the penetration depth and focusing effect of the ultrasonic signal can be optimized to meet different detection needs.

[0028] In this embodiment, the medium water is specifically degassed water. When using an ultrasonic handpiece, degassed water can reduce bubble formation, improve energy transfer efficiency, thereby enhancing the therapeutic effect and reducing unnecessary heat generation. It can also avoid errors or interference caused by dissolved gases in the water, thus obtaining more accurate results.

[0029] The above description is merely an embodiment of this utility model and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on this utility model will still fall within the scope of patent protection.
