[0025] The utility model provides an ultrasonic therapeutic apparatus 100.
[0026] Reference Figure 1 or Figure 2The embodiment of the ultrasonic therapeutic apparatus 100 includes a therapeutic head 1 and a negative pressure component. The therapeutic head 1 has a therapeutic surface 11 for contacting the skin. A flange 13 is convexly provided on the edge of the therapeutic surface 11. The flange 13 and the therapeutic surface 11 enclose a negative pressure cavity 14; the negative pressure component includes a negative pressure channel 5 and an air suction pump (not shown) connected to the negative pressure channel 5. An air suction port 111 is provided on the therapeutic surface 11. The negative pressure channel 5 passes through the cavity of the therapeutic head 1 and is connected to the air suction port 111. The air suction pump is used to extract the air in the negative pressure cavity 14, so that the skin is closely attached to the therapeutic surface 11 under the action of suction.
[0027] Different from the conventional ultrasonic therapeutic apparatus, the ultrasonic therapeutic apparatus 100 is provided with a flange 13 on the edge of the treatment surface 11, and the flange 13 and the treatment surface 11 are enclosed to form a negative pressure cavity 14, and a negative pressure component is added, the negative pressure component includes a negative pressure channel 5 and an air pump (not shown) connected to the negative pressure channel 5, and an air suction port 111 is provided on the treatment surface 11, and the negative pressure channel 5 is inserted into the cavity of the treatment head 1 and connected to the air suction port 111. During treatment, a coupling agent (gel) is applied to the skin to be treated, and then the treatment surface 11 of the treatment head 1 is attached to the skin surface, and a negative pressure cavity 14 is formed between the skin surface, the treatment surface 11 and the flange 13, and then the air suction pump is started to evacuate, the air in the negative pressure cavity 14 is evacuated, and the skin is pulled upward under the action of the negative pressure suction force, so that it is closely attached to the treatment surface 11 of the treatment head 1, so as to achieve the purpose of precise treatment.
[0028] The vertical distance between the bottom surface of the flange 13 and the treatment surface 11 is defined as d, and d satisfies the following condition: 0<d≤5mm, thereby providing space for lifting the skin upward. The end of the flange 13 facing the skin is rounded to prevent the flange 13 from scratching the skin.
[0029] An enclosure block 51 is protruding from the inner wall of the negative pressure channel 5 , and the enclosure block 51 is used to prevent the coupling agent from being quickly drawn into the negative pressure channel 5 to avoid blockage of the negative pressure channel 5 .
[0030] The negative pressure channel 5 is made of a coupling agent-sparing material, such as PTFE, FEP, ECTE, ETFE, PFA, etc., so as to prevent the coupling agent from being absorbed by the negative pressure channel 5 .
[0031] Preferably, the air suction port 111 is arranged at the center of the treatment head 1, so that the skin is evenly adsorbed. Specifically, the center of the treatment surface 11 is concave to form an air avoidance groove 112, and the air suction port 111 is opened on the bottom wall of the air avoidance groove 112, which prevents the negative pressure channel 5 from directly sucking away the coupling agent from the skin, and prevents the coupling agent from flowing into the negative pressure channel 5 laterally along the treatment surface 11, causing the negative pressure channel 5 to be blocked.
[0032] The ultrasonic therapeutic device 100 also includes an ultrasonic transducer 2. The piezoelectric material layer of the ultrasonic transducer 2 vibrates under a high-frequency voltage to generate ultrasonic waves. The ultrasonic waves are focused on a preset treatment position, causing the skin tissue at the preset treatment position to vibrate and be heated, thereby stimulating collagen regeneration.
[0033] In one embodiment, the ultrasonic transducer 2 is movably disposed in the chamber of the treatment head 1 and emits ultrasonic waves toward the treatment surface 11. If a sliding track is provided in the treatment head 1, the ultrasonic transducer 2 is slidably connected to the treatment head 1 through the sliding track, thereby realizing position movement. Each ultrasonic transducer 2 has a preset travel trajectory and can reciprocate between its own travel start point and travel end point, thereby radiating a larger treatment area, thereby reducing the number of sliding times of the ultrasonic treatment head 1 and reducing the consumption rate of the coupling agent.
[0034] In one embodiment, the ultrasonic therapeutic apparatus 100 includes an ultrasonic transducer unit, which includes a plurality of ultrasonic transducers 2, which are arrayed in the chamber of the treatment head 2 and emit ultrasonic waves toward the treatment surface 11. Compared with non-array ultrasonic therapeutic apparatuses, array-type ultrasonic therapeutic apparatuses have a larger treatment area and can also reduce the number of sliding times of the treatment head 1, thereby reducing the consumption rate of the coupling agent (such as gel).
[0035] In another embodiment, the ultrasonic transducer unit includes a first ultrasonic transducer assembly 3 and a second ultrasonic transducer assembly 4, the second ultrasonic transducer assembly 4 surrounds the first ultrasonic transducer assembly 3 and is arranged concentrically with the first ultrasonic transducer assembly 3, and the negative pressure channel 5 is arranged at the center of the first ultrasonic transducer assembly 3. Thus, the focusing center of the ultrasonic transducer unit overlaps with the adsorption center, so that the ultrasonic energy is evenly distributed in the treatment area.
[0036] Among them, the first ultrasonic transducer assembly 3 and the second ultrasonic transducer assembly 4 may both be annular ultrasonic transducers; or, the first ultrasonic transducer assembly 3 and the second ultrasonic transducer assembly 4 may both be composed of a plurality of ultrasonic transducers arranged in annular arrays; or the first ultrasonic transducer assembly 3 is an annular ultrasonic transducer, and the second ultrasonic transducer assembly 4 is composed of a plurality of ultrasonic transducers arranged in annular arrays; or the first ultrasonic transducer assembly 3 is composed of a plurality of ultrasonic transducers arranged in annular arrays, and the second ultrasonic transducer assembly 4 is an annular ultrasonic transducer.
[0037] Furthermore, the first ultrasonic transducer 3 has a first emitting surface, the second ultrasonic transducer 4 has a second emitting surface, the first emitting surface and the second emitting surface are both concave surfaces, and the ultrasonic waves emitted by the first emitting surface and the second emitting surface are both focused on the extension line of the negative pressure channel 5, thereby ensuring that the focus point of the ultrasonic wave is focused on the adsorption center, further realizing precise treatment. Among them, the first ultrasonic transducer 3 and the second ultrasonic transducer 4 can have the same or different focal depths.
[0038] A substrate 12 for mounting an ultrasonic transducer is provided in the chamber of the treatment head 1, and a first mounting groove 121 and a second mounting groove 122 are concavely provided in an annular manner on one side of the substrate 12 facing the treatment surface 11. The first ultrasonic transducer 3 is embedded in the first mounting groove 121 to be detachably connected to the substrate 12, and the second ultrasonic transducer 4 is embedded in the second mounting groove 122 to be detachably connected to the substrate 12. The detachable connection may be a screw connection, a clamping connection, etc., so as to facilitate the disassembly, replacement or maintenance of the first ultrasonic transducer 3 and the second ultrasonic transducer 4.
[0039] Some embodiments of the ultrasonic therapeutic device 100 also include an electrically connected controller (not shown) and a pressure sensor 6. The pressure sensor 6 is disposed in the negative pressure chamber 14 and is used to monitor the pressure value in the negative pressure channel 5 and transmit a signal to the controller. The controller controls the operation of the ultrasonic therapeutic device 100 according to the received signal.
[0040] Specifically, the pressure sensor 6 is provided with a first threshold value and a second threshold value. When the pressure sensor 6 monitors that the pressure value in the negative pressure chamber 14 is within the range of the first threshold value and the second threshold value, the controller controls the ultrasonic transducer 2 to normally emit ultrasonic waves; when the pressure sensor 6 monitors that the pressure value in the negative pressure chamber 14 is less than the first threshold value, the controller controls the ultrasonic transducer 2 not to work; when the pressure sensor 6 monitors that the pressure value in the negative pressure chamber 14 is greater than the second threshold value, the controller controls the vacuum pump to reduce its working efficiency until the pressure value returns to between the first threshold value and the second threshold value.
[0041] Furthermore, an embodiment of the ultrasonic therapeutic apparatus 100 further includes a displacement sensor 7 electrically connected to the controller, and the displacement sensor 7 is mounted on the treatment head 1 to monitor the moving speed of the treatment head 1. The displacement sensor 7 is provided with a first threshold speed and a second threshold speed, and the first threshold speed is greater than the second threshold speed. When the displacement sensor 7 monitors that the moving speed of the treatment head 1 reaches the first threshold speed, the controller controls the suction pump to increase the suction force, and when the displacement sensor 7 monitors that the moving speed of the treatment head 1 is less than the second threshold speed, the controller controls the suction pump to reduce the suction force.
[0042] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
