Description

Technical Field

[0001] This application relates to the field of physiotherapy equipment technology, specifically to a microneedle physiotherapy device. Background Technology

[0002] With the popularization of cosmetic physiotherapy, microneedling therapy has a wide range of applications. The principle of microneedling therapy is to make micro-holes or punctures in the skin tissue with microneedles to create micro-physical damage to the skin.

The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0024] like Figures 1 to 8As shown, this application embodiment provides a microneedle therapy device, including a housing 10, a therapy component 20, and a temperature-changing component 30; the housing 10 has a receiving cavity 11 and a therapy plane 12, the therapy plane 12 is located on the outer wall surface of the housing 10, and the therapy plane 12 is provided with an active hole 13 communicating with the outside, the receiving cavity 11 is connected to the active hole 13; the therapy component 20 has a telescopic head 21, the telescopic head 21 is movably disposed in the active hole 13 to enter or extend into the active hole 13, and the surface of the telescopic head 21 has microneedle components for contacting the skin; the temperature-changing component 30 is installed in the receiving cavity 11, and the temperature-changing component 30 is thermally connected to the therapy plane 12 to heat or cool the therapy plane 12.

[0025] In this embodiment, a physiotherapy component 20 and a temperature-regulating component 30 are provided inside the housing 10. The physiotherapy component 20 has a telescopic head 21, which can telescopically move relative to the housing 10. A movable hole 13 is provided on the physiotherapy surface 12 of the housing 10, allowing the telescopic head 21 to extend or enter relative to the movable hole 13. The surface of the telescopic head 21 has a microneedle component. During microneedle therapy, the movement of the telescopic head 21 can drive the microneedle component to perform needle insertion on the skin to complete the microneedle therapy. The temperature-regulating component 30 can cool or heat the physiotherapy surface 12. During physiotherapy, the physiotherapy surface 12 can contact the skin. The temperature-regulating component can first heat the physiotherapy surface 12 and then apply a hot compress to the skin to promote blood circulation and open pores. Alternatively, the temperature-regulating component can cool the physiotherapy surface 12 during the microneedle therapy process, allowing a cold compress to be applied to a certain area of ​​the skin after microneedle therapy. With this design, this microneedle therapy device can not only perform microneedle therapy on the skin, but also provide cold or hot compresses, making it versatile. The device integrates the microneedle components and the temperature-regulating components, eliminating the need to find additional tools for cold or hot compresses, simplifying the operation and enhancing the user experience.

[0026] In this embodiment, the temperature-changing component 30 can be thermally connected to the physiotherapy surface 12 via a heat-conducting copper pipe; or, the temperature-changing component 30 can be in close contact with the physiotherapy surface 12 for direct heat exchange; or, the temperature-changing component 30 can be disposed adjacent to the physiotherapy surface 12 and can exchange heat with the physiotherapy surface 12 via air, which is not limited here.

[0027] Furthermore, when using the telescopic head 21 for microneedling therapy, needles are typically inserted sequentially along a path. The angle of the microneedling therapy device is adjusted so that the movable hole 13 is aligned with the path. That is, the telescopic head 21 will first contact the skin along the path, and then the therapy surface 12 will contact the skin. With this setup, when performing microneedling therapy, the telescopic head 21 inserts needles at the front end first, and then a preliminary and rapid cold compress can be applied to the skin, which can reduce itching and redness. This allows for simultaneous microneedling therapy and cold compress, improving the efficiency of the therapy.

[0028] In other embodiments, before microneedling therapy, the temperature-controlled component 30 is heated. After the heat from the temperature-controlled component 30 is transferred to the therapy surface 12, the user can hold the entire housing 10 and adjust it to a suitable angle to avoid the microneedling component from contacting the skin. The therapy surface 12 is then aligned with the skin for heat application. After the entire area to be treated has been heated, the telescopic head 21 is aligned with the skin for microneedling therapy.

[0029] In some embodiments, such as Figures 1 to 3 As shown, the housing 10 includes a detachable upper cover 101 and a main body 102. A receiving cavity 11 is disposed in the main body 102. The upper cover 101 is used to cover the receiving cavity 11. A physiotherapy plane 12 is disposed on the side of the upper cover 101 away from the main body 102. An movable hole 13 is disposed on the upper cover 101. The temperature-changing component 30 has a heat exchange surface 31, which abuts against the inner wall of the upper cover 101 to transfer cold or heat to the physiotherapy plane 12.

[0030] Specifically, the upper cover 101 is detachably installed on the main body 102 and can cover part of the receiving cavity 11. The movable hole 13 is arranged around the upper cover 101. The upper cover 101 is made of a material with good thermal conductivity, such as aluminum, aluminum alloy, copper, or copper alloy. The heat exchange surface 31 of the temperature-changing component 30 abuts against the side of the upper cover 101 facing the main body 102 for better heat conduction or cooling. This arrangement allows tools or fingers to be inserted into the receiving cavity 11 by removing the upper cover 101, facilitating the installation or disassembly of the structure inside the receiving cavity 11. The heat exchange surface 31 of the temperature-changing component 30 will not directly contact the skin, reducing the risk of burns or frostbite and preventing contamination of the heat exchange surface 31.

[0031] In some other embodiments, the housing 10 includes a main body 102 and a top cover 101 that are fixedly connected to each other. The top cover 101 is glued to the main body 102 to achieve fixation.

[0032] In some embodiments, such as Figure 3 and Figure 7As shown, a magnetic suction member 14 is fixed to the side of the upper cover 101 facing the main body 102. The magnetic suction member 14 is magnetically connected to the main body 102 to fix the upper cover 101 to the main body 102.

[0033] Specifically, multiple magnetic suction components 14 are provided, evenly spaced along the outer periphery of the upper cover 101. In this embodiment, corresponding to the magnetic suction components 14 of the upper cover 101, multiple adsorption components are provided on the upper surface of the main body 102. The adsorption components and magnetic suction components 14 are arranged in a one-to-one correspondence, and the magnetic suction components 14 can be magnetically connected to the adsorption components. The magnetic suction components 14 are embedded in the upper cover 101, and the adsorption components are embedded in the upper surface of the main body 102. Alternatively, the upper surface of the main body 102 can be made of a magnetic material, allowing the upper cover 101 to be directly magnetically connected to the upper surface of the main body 102. This magnetic connection facilitates the quick disassembly and installation of the upper cover 101, and the addition of multiple magnetic suction components 14 increases the connection stability between the upper cover 101 and the main body 102. In other embodiments, a buckle is fixed to the side of the upper cover 101 facing the main body 102, and a slot is provided on the surface of the main body 102. The upper cover 101 is engaged with the main body 102 by snapping the buckle into the slot.

[0034] In some embodiments, such as Figure 2 As shown, the receiving cavity 11 is provided with a partition plate 15, which divides the receiving cavity 11 into a first chamber 111 and a second chamber 112 arranged in parallel. The first chamber 111 is connected to the movable hole 13. The physiotherapy component 20 is disposed in the first chamber 111, and the temperature-changing component 30 is detachably installed in the second chamber 112.

[0035] Specifically, such as Figure 2 As shown, the receiving cavity 11 is divided into a first chamber 111 and a second chamber 112, which are not interconnected, by a partition plate 15. The partition plate 15 extends vertically along the height of the housing 10, dividing the receiving cavity 11 into two chambers arranged to the left and right. The temperature-changing component 30 and the physiotherapy component 20 are respectively located in the second chamber 112 and the first chamber 111. This arrangement prevents the two components from contacting each other during operation, installation, and disassembly, and also ensures sufficient space for installation. At the same time, the partition plate 15 acts as a barrier, reducing the transfer of heat generated by the temperature-changing component 30 to the first chamber 111. In this embodiment, the partition plate 15 can be fixed to the cavity wall of the receiving cavity 11 by means of bonding, integral molding, or other methods.

[0036] In some other embodiments, a baffle is provided in the receiving cavity 11, and the physiotherapy component 20 and the temperature-changing component 30 are sequentially installed in the receiving cavity 11. The baffle is used to separate the two components and avoid direct contact.

[0037] Furthermore, the housing 10 also includes an embedded shell 16, which is detachably connected to the main body 102. A groove 103 is provided on one side of the main body 102, and a second chamber 112 is formed in the embedded shell 16. After the top cover 101 is removed, the embedded shell 16 can be inserted into the groove 103 to achieve installation. At least one groove sidewall on the groove 103 is in communication with the outside, that is, after the embedded shell 16 is inserted into the groove 103, part of the outer surface of the embedded shell 16 can be exposed through the groove 103.

[0038] In some embodiments, such as Figure 2 , Figure 3 and Figure 5 As shown, the temperature-changing component 30 includes a semiconductor cooling element 32 and a heat sink 33. The heat exchange surface 31 is one end face of the semiconductor cooling element 32, and the other end face of the semiconductor cooling element 32 abuts against the heat sink 33. The heat sink 33 is fixed in the second chamber 112. When the semiconductor cooling device 32 is cooling, the heat exchange surface 31 is used to transfer the generated cold energy to the upper cover 101, and the heat sink 33 is used to conduct heat out of the second chamber 112. When the semiconductor cooling device 32 is heated, the heat exchange surface 31 is used to transfer the generated heat to the upper cover 101, and the heat sink 33 is used to discharge the cold energy to the outside of the second chamber 112.

[0039] Specifically, the thermoelectric cooler 32 generates both cooling and heating when an electric current is applied. The heat exchange surface 31 is located on the side of the thermoelectric cooler 32 facing the upper cover 101. Thermal grease can be filled between the heat exchange surface 31 and the upper cover 101 to improve the contact between the thermoelectric cooler 32 and the upper cover 101. The thermoelectric cooler 32 is typically a block structure. Under normal conditions, one side of the thermoelectric cooler 32 is the heat exchange surface 31, which generates cooling and directs it to the therapeutic surface 12. At this time, the other side of the thermoelectric cooler 32 generates heat. When the positive and negative terminals of the circuit change, one side of the thermoelectric cooler 32 becomes the heat exchange surface 31. The heat exchange surface 31 generates heat and directs it to the therapy surface 12. The other side of the thermoelectric cooler 32 generates cooling. A heat sink 33 is installed on the side opposite to the heat exchange surface 31 and abuts against the thermoelectric cooler. When the thermoelectric cooler 32 is working, the heat sink 33 can conduct unwanted cooling or heat to the outside of the second chamber 112. This setup achieves both hot and cold compress functions with a single thermoelectric cooler, resulting in a relatively simple structure. The heat sink 33 reduces the accumulation of excess cooling or heat in the second chamber, ensuring the thermoelectric cooler functions properly and extending its lifespan. In other embodiments, the wall of the second chamber 112 has air vents, and an exhaust fan blows air outwards from the vents. In this embodiment, the heat sink can be made of materials with good thermal conductivity, such as copper, aluminum alloy, or aluminum.

[0040] In some embodiments, the temperature-changing component 30 includes a heating resistor that abuts against the inner wall of the housing 10. When the heating resistor is energized, it can generate heat, thereby transferring heat to the physiotherapy surface 12, which is then applied to the user's skin to achieve the function of hot compress.

[0041] In some embodiments, the temperature-changing component 30 is a miniature refrigeration compressor. The evaporator on the miniature refrigeration compressor exchanges heat with the physiotherapy surface 12, thereby cooling the physiotherapy surface 12 and placing it on the user's skin to achieve the function of cold compress.

[0042] In some embodiments, such as Figures 1 to 4 As shown, the second chamber 112 has multiple ventilation holes 113 through its cavity wall, which connect to the outside world and the radiator 33.

[0043] Specifically, the outer wall of the embedded shell 16 serves as the cavity wall of the second chamber 112, that is, multiple ventilation holes 113 are provided through the outer wall of the embedded shell 16. The embedded shell 16 has at least one side wall exposed outside the groove 103. In this embodiment, multiple ventilation holes 113 are evenly distributed on the exposed side wall, and multiple ventilation holes 113 are also provided on the opposite side of the side wall. The radiator 33 can take in air from the ventilation hole 113 on one side, and then the airflow in the second chamber 112 is directed to the ventilation hole 113 on the other side. The airflow can drive the cold or heat in the second chamber 112 to move. This arrangement can ensure that the second chamber 112 maintains airflow, thereby quickly dissipating the unwanted heat and cold in the second chamber 112.

[0044] In some embodiments, such as Figure 5 As shown, the temperature-changing component 30 also includes a fan. The heat sink 33 has an air duct 335 for airflow. The heat sink 33 has a fixing groove 333 connected to the air duct 335. The fan is installed in the fixing groove 333 and is positioned facing the ventilation hole 113 to guide airflow to the ventilation hole 113.

[0045] Specifically, the heat sink 33 consists of a base 332 and multiple fins 331 protruding from the base 332. The multiple fins 331 are arranged at intervals to form an air duct 335 for airflow. A portion of the fins 331 is cut to form a fixing groove 333 within the air duct 335. The fan is installed within the fixing groove 333. The base 332 is attached to the semiconductor cooling element 32, which can transfer heat or cold to the fins 331. The airflow blown by the fan passes through the air duct 335 and can exchange heat with the fins 331. The airflow after heat exchange flows towards the ventilation hole 113 to be discharged outside the second chamber 112. Compared with the conventional heat sink 33 structure, in this embodiment, the fan and heat sink 33 share the same installation space, which can reduce the space occupied by the heat sink 33 and reduce the overall size of the microneedle therapy device. In some other embodiments, the fan is installed on one side wall of the heat sink 33 and is used to draw airflow out of the air duct 335.

[0046] In some embodiments, such as Figure 2 and Figure 3 As shown, the microneedle therapy device also includes a liquid guiding component 40, which is disposed in the second chamber 112. The liquid outlet 17 is located on the therapy plane 12. The two ends of the liquid outlet pipe 42 are respectively connected to the liquid storage tank 41 and the liquid outlet 17. The liquid outlet pump 43 is installed in the liquid storage tank 41 and is used to pump liquid from the liquid storage tank 41 into the liquid outlet pipe 42. The radiator 33 is provided with a clearance channel 334, and at least part of the liquid outlet pipe 42 is inserted into the clearance channel 334, so that the radiator 33 can exchange heat with the liquid in the liquid outlet pipe 42.

[0047] Specifically, a liquid guiding component 40 is also provided in the groove 103. The liquid guiding component 40 includes a liquid storage tank 41 installed at the bottom of the embedded shell 16. A liquid outlet pump 43 is provided at the opening of the liquid storage tank 41. The liquid outlet pump 43 is sealed and connected to one end of the liquid outlet pipe 42. The liquid outlet pump 43 is a vacuum adsorption pump, which can pump the liquid in the liquid storage tank 41 to the liquid outlet pipe 42. The liquid outlet pipe 42 passes through the embedded shell 16. A liquid outlet hole 17 is provided on the upper cover 101. The liquid outlet hole 17 is sealed and connected to the other end of the liquid outlet pipe 42. The liquid outlet pipe 42 passes through the avoidance channel 334 of the radiator 33. In conjunction with the aforementioned embodiment, multiple fins 331 surround the liquid outlet pipe 42, that is, the liquid outlet pipe 42 will pass through the air duct 335. The airflow in the air duct 335 will interact with the liquid outlet pipe 42. The liquid in the liquid pipe 42 undergoes a certain degree of heat exchange. When the heat exchange surface of the semiconductor cooler 32 is cooled, the other end of the semiconductor cooler 32 located in the second chamber 112 will generate heat to heat the liquid in the liquid outlet pipe 42, thereby achieving local heating of the liquid. Especially in winter, this can reduce the irritation of the cold liquid to the skin. Conversely, when the heat exchange surface of the semiconductor cooler 32 is heated, the other end of the semiconductor cooler 32 located in the second chamber 112 will generate cold energy to cool the liquid in the liquid outlet pipe 42. Especially in summer, the cooled liquid can enhance the cooling sensation when skin care. The liquid outlet pump 43 is electrically connected to the magnetic contact 161, and the circuit board 51 can control the operation of the liquid outlet pump 43 and the function of the semiconductor cooler 32. With this configuration, the microneedle therapy device of this application embodiment also has a liquid dispensing function. During microneedle therapy, the liquid dispensing pump 43 can be controlled to discharge the liquid from the liquid dispensing hole 17 on the therapy plane 12, thereby flowing into the skin tissue to further enhance the therapeutic effect. The liquid dispensing can also be heated or cooled.

[0048] In one embodiment, the liquid outlet pipe 42 is spaced apart from the upper cover 101, and a heat insulation layer is provided between the liquid outlet pipe 42 and the upper cover 101. One end of the liquid outlet pipe 42 is connected to the liquid storage tank 41, and the other end passes through the clearance channel 334 of the radiator 33 and the liquid outlet hole 17 of the upper cover 101 in sequence before protruding outward from the upper cover 101. The radiator 33 is in close contact with the liquid outlet pipe 42. In this way, the radiator 33 can heat the part of the liquid outlet pipe 42 that passes through the clearance channel 334 without heating all the liquid in the liquid storage tank 41. The liquid outlet pipe 42 does not directly contact the upper cover 101, which can reduce the heat exchange between the upper cover 101 and the liquid in the liquid outlet pipe 42, and improve the heating or cooling effect of the liquid in the liquid outlet pipe 42. In some embodiments, such as Figure 2 and Figure 3As shown, the microneedle therapy device also includes a circuit board 51 and a battery 52. ​​The circuit board 51 is installed inside the housing 10 and located at the bottom of the housing 10. Electrode contacts 104 are provided on the inner wall of the groove 103, and the electrode contacts 104 are electrically connected to the circuit board 51. Magnetic contacts 161 are provided on the outer peripheral wall of the embedded shell 16 corresponding to the electrode contacts 104. The temperature-changing component 30 is electrically connected to the magnetic contacts 161. When the embedded shell 16 is inserted into the groove 103, the magnetic contacts 161 can be magnetically connected to the electrode contacts 104 to achieve temperature-changing... Component 30 is electrically connected to circuit board 51. Two buttons are provided on the bottom wall of housing 10. One button is used to control the switching of the modes of temperature-changing component 30 and physiotherapy component 20, and the other button is used to control the main power switch. Both buttons are electrically connected to circuit board 51. Battery 52 is electrically connected to circuit board 51 and is used to supply power to temperature-changing component 30, physiotherapy component 20 and fluid guiding component 40. A charging hole is provided on the main body 102 and is electrically connected to circuit board 51. The charging hole is used to charge battery 52.

[0049] In some embodiments, such as Figure 2 and Figure 8 As shown, the microneedle therapy device also includes two microcurrent electrodes 53. The microcurrent electrodes 53 are used to contact the skin. The microcurrent electrodes 53 are installed on the upper cover 101 and protrude from the therapy plane 12. One end of the microcurrent electrode 53 located on the outside of the housing 10 is used to contact the skin. The other end of the microcurrent electrode 53 is electrically connected to the circuit board 51 through a conductive spring needle or conductive wire. When the two microcurrent electrodes 53 contact the skin at the same time, the circuit board 51 can be controlled to send a microcurrent to the microcurrent electrodes 53 to perform microcurrent therapy on the human skin.

[0050] In some embodiments, such as Figure 3 and Figure 6 As shown, the physiotherapy component 20 also includes a drive motor 22 and a transmission mechanism. The two ends of the transmission mechanism are respectively connected to the drive motor 22 and the telescopic head 21. The transmission mechanism includes a push rod 24 and a rotating wheel 23. The rotating wheel 23 is sleeved on the drive shaft of the drive motor 22. The side of the rotating wheel 23 away from the drive motor 22 has an inclined surface 231. One end of the push rod 24 is connected to the telescopic head 21, and the other end is used to abut against the inclined surface 231. The drive motor 22 can drive the rotating wheel 23 to rotate. When the rotating wheel 23 rotates, the inclined surface 231 can intermittently abut against the push rod 24, thereby realizing the reciprocating motion of the push rod 24 along the axial direction of the movable hole 13.

[0051] Specifically, a drive motor 22 is installed in the first chamber 111. The drive motor 22 is electrically connected to the circuit board 51. The transmission mechanism includes a limiting shell 26, a push rod 24, and a rotating wheel 23. A rotating wheel 23 is sleeved on the drive shaft of the drive motor 22. The limiting shell 26 is sleeved on the outside of the drive motor 22, the rotating wheel 23, and the top cover. The limiting shell 26 can limit the push rod 24, thereby limiting the push rod 24 to only move axially. The side of the rotating wheel 23 away from the drive motor 22 has an inclined surface 231. The inclined surface 231 is used to abut the bottom of the push rod 24. The other end of the push rod 24 is connected to the telescopic head 21. When the drive motor 22 drives, the rotating wheel 23 rotates continuously, and the inclined surface 231 can intermittently abut the push rod 24. When abutting, the push rod 24 is pushed up, and the telescopic head 21 extends out of the movable hole 13. When not abutting, the push rod 24 falls down, and the telescopic head 21 retracts into the movable hole 13. Compared to cam and linkage structures, this configuration, while fulfilling the intermittent lifting function, results in a smaller structure with less radial space, leading to a more compact overall design. In other embodiments, the transmission mechanism is a linkage-slider mechanism, with the drive shaft of the drive motor 22 connected to the linkage group. The telescopic head 21 is fixed to the slider, and when the drive motor 22 starts, the slider reciprocates under the drive of the linkage group.

[0052] Furthermore, the microneedle component is a replaceable microneedle patch. Before microneedling therapy, the microneedle patch is attached to the surface of the telescopic head 21. When the telescopic head 21 is in motion, the microneedles on the patch can be used to puncture the skin to complete the microneedling therapy. In other embodiments, the microneedle component may not be integrally formed with the telescopic head 21, which is not limited here.

[0053] In some embodiments, the physiotherapy component 20 includes a pressing block, a push rod, and a first spring. The pressing block is a wedge-shaped block and is movably mounted on the surface of the main body 102. The push rod is disposed in the first chamber 111. One end of the push rod is connected to the telescopic head 21, and the other end is drivenly connected to the pressing block. The pressing block is a wedge-shaped block, and the other end of the push rod has a sliding inclined surface that matches the wedge-shaped block. The pressing block is slidably connected to the inclined surface of the push rod. The first spring is sleeved on the push rod. One end of the first spring is fixed to the push rod, and the other end abuts against the cavity wall of the first chamber 111. When the pressing block is pressed towards the interior of the main body 102, it drives the push rod along the axial direction of the movable hole 13, thereby pushing the telescopic head 21 out of the movable hole 102. At this time, the first spring is in a compressed state. When the pressing block is released, the elastic force of the first spring can drive the push rod to move, causing the telescopic head 21 to retract into the movable hole 13. The pressing block is pressed repeatedly to achieve the action of repeated acupuncture.

[0054] In some embodiments, such as Figure 6As shown, the transmission mechanism also includes a return spring 25, which is sleeved on the outer periphery of the push rod 24. The bottom of the push rod 24 is provided with an arc-shaped protrusion 241, which is used to abut against the inclined surface 231. One end of the return spring 25 is fixed to the mounting cavity, and the other end is fixed to the push rod 24. When the inclined surface 231 abuts against the arc-shaped protrusion 241, the return spring 25 is compressed.

[0055] Specifically, the bottom of the push rod 24 has an outwardly protruding arc-shaped protrusion 241. A stop cover 242 is also provided on the outer peripheral wall of the push rod 24. The arc-shaped protrusion 241 is located below the stop cover 242. The return spring 25 is sleeved on the push rod 24. One end of the return spring 25 abuts against the stop cover 242, and the other end abuts against the top wall of the limiting shell 26. When the arc-shaped protrusion 241 abuts against the inclined surface 231, the inclined surface 231 can push the push rod 24 upward, and the telescopic head 21 extends out of the movable hole 13. When the arc-shaped protrusion 241 does not abut against the inclined surface 231, under the action of the return spring 25, the push rod 24 will move downward a certain distance, and the telescopic head 21 will retract into the movable hole 13, thus realizing the reciprocating telescopic movement of the push rod 24.

[0056] In some embodiments, such as Figure 2 and Figure 3 As shown, the telescopic head 21 is made of a light-transmitting material. The microneedle therapy device also includes a phototherapy lamp plate 50, which is located inside the receiving cavity 11. The phototherapy lamp plate 50 is positioned close to the telescopic head 21, and the light emitted by the phototherapy lamp plate 50 can pass through the telescopic head 21 and be emitted outward.

[0057] Specifically, the phototherapy lamp plate 50 is fixed to the first chamber 111. The phototherapy lamp plate 50 is an annular plate with multiple light-emitting LEDs facing outwards from the movable hole 13. The telescopic head 21 is fitted with the movable hole 13 with a small clearance. The phototherapy lamp plate 50 surrounds the telescopic head 21. Both the telescopic head 21 and the microneedle patch are made of light-transmitting material. When the phototherapy lamp plate 50 emits light, light can pass through the telescopic head 21 itself and its outer periphery. This arrangement allows light to pass through the movable hole 13 to perform phototherapy on the skin during microneedle therapy, improving the therapeutic effect for the user. In other embodiments, the phototherapy lamp plate 50 is positioned below the therapeutic plane 12, and the upper cover 101 is made of light-transmitting material, allowing the light from the phototherapy lamp plate 50 to pass through the therapeutic plane 12.

[0058] In some embodiments, such as Figure 2 and Figure 8As shown, the housing 10 also includes a storage cavity 105, which is located below the second chamber 112. The storage cavity 105 is provided with a shelf 18 having multiple shelves, with a storage position between any two shelves. The microneedle assembly can be a microneedle patch. Each storage position can hold an unused microneedle patch. The storage cavity 105 also has an opening that communicates with the outside. A door panel 106 is provided at the opening to seal and close the opening. When the microneedle patch needs to be used, the door panel 106 is opened and the microneedle patch is taken out from the storage position. Each microneedle patch can be individually packaged to prevent the microneedle patch from being contaminated.

[0059] In some embodiments, a UV disinfection lamp (not shown) is provided in the storage cavity 105. The UV light emitted by the UV disinfection lamp can disinfect the microneedle patch in the storage cavity 105, thereby improving the hygiene of the microneedle patch.
