Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a light window device and a handle. Background Technology

[0002] In the field of aesthetic medicine, medical devices such as intense pulsed light (IPL) and laser therapy are being used more and more widely. To address the pain caused to users by intense light irradiation during treatment, cooling is usually applied to the light window that comes into contact with the skin to reduce pain.

[0003] However, during the cooling process, a large amount of water droplets condense on the contact surface between the light window device and the air due to the low temperature. These water droplets exist in a mist-like form in the early stages of cooling, but they will coalesce into water droplets over time. Both the mist and the droplets cause interface scattering or reflection of light, which greatly affects the output efficiency and treatment effect of the laser. In severe cases, it may even cause problems such as burning out the light source or exploding the lamp due to reflected light. Since the water droplets on the inside of the light window device are difficult to clean, the condensation problem is often solved by regularly replacing the light window device, which increases the operating cost. Summary of the Invention

[0004] The main objective of this invention is to provide a light window device and handle that prevents condensation from forming on the inside of the light window device, thereby increasing the product's lifespan and reducing usage costs.

[0005] To achieve the above objectives, the present invention provides a light window device, the light window device comprising:

[0006] A light-transmitting component, having a light-incident surface and a contact surface, wherein the light-incident surface and the contact surface are disposed opposite to each other; and

[0007] A cooling assembly includes a cooling element, a cooling conductive element, and a heat conductive element. The cooling surface of the cooling element is connected to the cooling conductive element, and the heat dissipation surface of the cooling element is connected to the heat conductive element. At least a portion of the heat conductive element extends to the light-incident surface and abuts against the light-incident surface. The cooling conductive element is disposed facing the contact surface.

[0008] In one embodiment, the cooling component is provided with an annular groove, and the cooling component is disposed within the annular groove.

[0009] In one embodiment, the cooling element is disposed on the outer peripheral side of the cooling conductor.

[0010] In one embodiment, the cooling element is disposed on the side of the cooling conductor away from the contact surface.

[0011] In one embodiment, the heat-conducting element includes a first portion and a second portion connected at an angle, the first portion being connected to the heat dissipation surface of the cooling element, and the second portion being connected to the light-incident surface.

[0012] In one embodiment, the second portion is arranged in a ring shape, and the second portion is arranged along the periphery of the light-incident surface.

[0013] In one embodiment, the heat-conducting component is provided with a heat dissipation channel and an inlet and an outlet connecting the heat dissipation channel, the heat dissipation channel being used for the flow of heat dissipation fluid.

[0014] In one embodiment, the light-transmitting component includes a light-transmitting element;

[0015] The contact surface is provided on the cooling component, and the cooling component is also provided with a first light-transmitting surface and a first peripheral side surface. The first light-transmitting surface is disposed opposite to the contact surface, and the first peripheral side surface is disposed between the first light-transmitting surface and the contact surface.

[0016] The light-transmitting element has a second light-transmitting surface, a second peripheral side surface, and a light-incident surface. The second light-transmitting surface and the light-incident surface are disposed opposite to each other, and the second peripheral side surface is disposed between the second light-transmitting surface and the light-incident surface.

[0017] A heat insulation frame is connected to the first light-transmitting surface and the second light-transmitting surface respectively to enclose and form a sealed cavity.

[0018] In one embodiment, the heat insulation frame is disposed along the periphery of the first light-transmitting surface, and / or, the heat insulation frame is disposed along the periphery of the second light-transmitting surface.

[0019] In one embodiment, the heat insulation frame is made of aerogel.

[0020] In one embodiment, the sealed cavity is filled with dry gas or is set to a vacuum.

[0021] In one embodiment, the contact surface is coated with an antireflective film and a hydrophilic film, wherein the hydrophilic film is disposed on the side of the antireflective film facing away from the contact surface.

[0022] In one embodiment, the first light-transmitting element and the second light-transmitting element are made of sapphire glass, high thermal conductivity transparent ceramic, or high thermal conductivity transparent crystal.

[0023] The present invention also proposes a handle, the handle comprising the light window device as described above.

[0024] In the technical solution of this invention, therapeutic light such as laser or pulsed light enters the light-transmitting component through its light-incident surface and exits from its contact surface to treat the treatment area.

[0037] In related technologies, in order to solve the problem of pain caused to users by strong light irradiation during treatment with medical devices such as intense pulsed light and laser therapy instruments, the pain of users is often reduced by cooling the light window device that is in direct contact with these devices during the treatment process.

[0038] However, during the cooling process, a large amount of water droplets condense on the contact surface between the light window device and the air due to the low temperature. These water droplets exist in a mist-like form in the early stages of cooling, but they will coalesce into water droplets over time. Both the mist and the droplets cause interface scattering or reflection of light, greatly affecting the output efficiency and treatment effect of the laser. In severe cases, reflected light may cause problems such as burning out the light source or exploding the lamp. The light window device usually has two spaced-apart light-transmitting bodies, and water mist will be generated on the inner light-transmitting surfaces of the two bodies due to cooling. Since the water droplets on the inside of the light window device are difficult to clean, the condensation problem is often solved by periodically replacing the light window device, which increases the operating cost.

[0039] Based on the above concepts and problems, such as Figure 1-2 As shown, this invention proposes a light window device 100, which includes a light-transmitting component 1 and a cooling component 2. The light-transmitting component 1 has a light-incident surface 123 and a contact surface 111, which are disposed opposite to each other. The cooling component 2 includes a cooling element 21, a cooling conductive element 11, and a heat-conducting element 22. The cooling surface of the cooling element 21 is connected to the cooling conductive element 11, and the heat-conducting surface of the cooling element 21 is connected to the heat-conducting element 22. At least a portion of the heat-conducting element 22 extends to and abuts against the light-incident surface 123, and the cooling conductive element 11 is disposed towards the contact surface 111. It should be noted that one or more components included in the light-transmitting component 1 and the cooling component 2 are functionally defined components and do not represent individuals with a fixed connection relationship to each other.

[0040] In this embodiment, therapeutic light such as laser or pulsed light enters the light-transmitting component 1 through the light-incident surface 123 and exits from the contact surface 111 of the light-transmitting component 1 to treat the treatment site. During treatment, the contact surface 111 is close to the treatment site, and the cooling component 21 cools the contact surface 111. Specifically, the contact surface 111 can be disposed on the cooling conductor 11 or on the outermost side of the cooling conductor 11. The cooling component 21 has a cooling surface and a heat dissipation surface. When the cooling component 21 is working, according to the law of conservation of energy, it cools the cooling surface, and at the same time, other parts will inevitably heat up. The heat generated is dissipated through the heat dissipation surface. The cooling surface of the cooling component 11 is close to the cooling conductor 11. The cooling conductor is made of a high thermal conductivity material, preferably sapphire glass, but other high thermal conductivity materials such as transparent ceramics or transparent crystals can also be used. It needs to meet the requirements of allowing laser to pass through and having high thermal conductivity. The cooling surface of the cooling component 21 is close to the cooling conductor 21, with the cooling conductor facing the contact surface 111. This conducts the cold generated by the cooling component 21 to the treatment area, reducing pain through cooling. Simultaneously, the heat-conducting component 22, connected to the heat dissipation surface of the cooling component 21, dissipates heat from the cooling component 21, ensuring its cooling effect. At least a portion of the heat-conducting component 22 extends to the light-incident surface 123 of the light-transmitting component 1, ensuring that the temperature of the light-incident surface 123 is not lower than room temperature. This prevents condensation on the light-incident surface 123, thus guaranteeing the light transmission quality of the light window device 100, extending its service life, reducing its replacement frequency, and lowering operating costs.

[0041] In practical implementation, the cooling component 21 can be a semiconductor refrigerator, also known as a TEC refrigerator, which is a device that uses the thermoelectric effect of semiconductors for cooling. It achieves cooling or heating by passing a direct current through a couple composed of two different metals or semiconductor materials, generating the Peltier effect. Semiconductor refrigerators have advantages such as small size, light weight, no moving parts, quiet operation, and no pollution, making them particularly suitable for fields requiring precise temperature control. Semiconductor refrigerators operate based on the Peltier effect; when a direct current passes through a couple composed of two different metals or semiconductor materials, one end of the couple absorbs heat, and the other end releases heat, thus achieving a cooling effect. By adjusting the direction and magnitude of the current through the couple, the cooling or heating end of the couple, as well as the cooling and heating temperatures, can be changed. A semiconductor refrigerator consists of many N-type and P-type semiconductor particles arranged together and connected by conductors to form a circuit. These circuits are sandwiched between two ceramic plates, which form the cold and hot ends. The cold end is used to cool the target object, while the hot end dissipates heat through a fan or water cooling system. Therefore, the cooling component 21 has a cooling surface and a heat dissipation surface. The cooling surface of the cooling component 21 is closely attached to the cooling conductor 11 to ensure the cooling effect on the treatment area. The heat dissipation surface of the cooling component 21 is closely connected to the heat conductor 22 to improve the heat transfer efficiency between the heat dissipation surface and the heat conductor 22, and to ensure the heat dissipation efficiency of the heat conductor 22 on the heat dissipation surface.

[0042] In one embodiment of the present invention, such as Figure 2 As shown, the cooling component 21 is disposed inside the cooling conductor 11, and the cooling surface of the cooling component 21 faces the contact surface 111 below the cooling conductor 11. Meanwhile, the heat dissipation surface of the cooling component 21 is at the edge of the cooling conductor 11. The cooling conductor 11 may be provided with an annular groove for accommodating the cooling component 21. At the same time, the heat dissipation surface of the cooling component 21 is on the outside and connected to the heat conductor 22, so that heat is transferred to the heat conductor 22 and then to the light incident surface 123.

[0043] In one embodiment of the present invention, such as Figure 1 As shown, the cooling component 21 is disposed on the outer periphery of the cooling component 11.

[0044] In one embodiment of the present invention, such as Figure 4 and Figure 5 As shown, the cooling component 21 is disposed on the side of the cooling conductor 11 away from the contact surface 111. The cooling surface of the cooling component 21 is connected to the cooling conductor 11 to transfer the cooled air to the contact surface 111. The heat dissipation surface of the cooling component 21 is connected to the heat conductor 22. The cooling surface and heat dissipation surface of the cooling component 21 are different surfaces, preferably disposed relatively far apart, such as... Figure 4 As shown, the lower part of the cooling component 21 is a cooling surface connected to the cooling conductive component 11, and the upper part is a heat dissipation surface connected to the heat conductive component 22. Figure 5In the middle, the heat dissipation surface has two sides, with the top and side being heat dissipation surfaces. The corresponding heat conduction component 22 has an irregular structure with the same shape as the heat dissipation surface, so that the heat dissipation surface and the heat conduction component 22 have the maximum contact area, thereby improving the heat dissipation effect.

[0045] In one embodiment of the present invention, such as Figure 1 As shown, the heat-conducting component 22 includes a first part 221 and a second part 222 connected at an angle. The first part 221 is connected to the heat dissipation surface of the cooling component 21, and the second part 222 is connected to the light-incident surface 123.

[0046] In this embodiment, the first part 221 is connected to the cooling component 21 to dissipate heat from the cooling component 21. The second part 222 is connected to the first part 221 at an angle, so that the second part 222 extends to the light-receiving surface 123 and connects with the light-receiving surface 123 to ensure that the temperature of the light-receiving surface 123 is not lower than the room temperature and to prevent condensation from forming on the light-receiving surface 123. The second part 222 is also provided with a light inlet 226 communicating with the light-receiving surface 123. The therapeutic light, such as laser or pulsed light, reaches the light-receiving surface 123 through the light inlet 226 to prevent the second part 222 from interfering with the normal irradiation of the laser or pulsed light onto the light-receiving surface 123.

[0047] In actual implementation, the first part 221 is spaced apart from the first peripheral side 112 of the cooling component 1. The cooling component 21 is located between the first peripheral side 112 and the first part 221. The cooling surface of the cooling component 21 is in close contact with the first peripheral side 112, and the heat dissipation surface of the cooling component 21 is in close contact with the first part 221. Optionally, the cooling component 21 is cylindrical or plate-shaped, with the cooling surface and heat dissipation surface arranged in parallel. The connection angle between the second part 222 and the first part 221 is consistent with the connection angle between the light-incident surface 123 and the first peripheral side 112, so as to facilitate the installation and connection of the heat-conducting component 22 and the light-transmitting component 1.

[0048] In one embodiment of the present invention, such as Figure 1 As shown, the second part 222 is arranged in a ring shape, and the second part 222 is arranged along the periphery of the light-incident surface 123.

[0049] In this embodiment, the second part 222 is arranged in a ring shape to enclose and form the light entrance 226. The second part 222 is arranged along the periphery of the light entrance surface 123. In this way, without interfering with the normal light transmission of the light transmission component 1, the contact area between the second part 222 and the light entrance surface 123 is maximized, thereby ensuring the heat transfer effect between the second component and the light entrance surface 123. This keeps the temperature of the light entrance surface 123 in a stable state that is not lower than the room temperature.

[0050] In actual implementation, at least a portion of the second part 222 overlaps with the light-incident surface 123, and the overlapping portion is in close contact with the light-incident surface 123 to ensure the heat transfer effect between the second part 222 and the light-incident surface 123.

[0051] In one embodiment of the present invention, such as Figure 1 As shown, the heat-conducting component 22 is provided with a heat dissipation channel 223 and an inlet 224 and an outlet 225 that connect the heat dissipation channel 223. The heat dissipation channel 223 is used for the flow of heat dissipation fluid.

[0052] In this embodiment, the heat-conducting component 22 is provided with a heat dissipation channel 223 for the flow of heat dissipation liquid. The heat dissipation liquid flows in the heat dissipation channel 223 to carry away the heat of the heat-conducting component 22, thereby ensuring the heat dissipation effect of the heat-conducting component 22 on the cooling component 21.

[0053] Understandably, the heat-conducting component 22 includes a first portion 221 and a second portion 222 at an angle. The first portion 221 may be arranged around the first circumferential side 112, and the inlet 224 and outlet 225 of the heat dissipation channel 223 are spaced apart in the first portion 221. Optionally, the heat dissipation channel 223 starts from the inlet 224, then extends within the first portion 221 and ends at the outlet 225; or, the heat dissipation channel 223 starts from the inlet 224, then extends within the first portion 221, then extends from the first portion 221 into the second portion 222, then extends again from the second portion 222 into the first portion 221, and finally ends at the outlet 225. No specific limitation is made here. The heat dissipation channel 223 may be meandering within the heat-conducting component 22 to increase the flow area of ​​the heat sink and improve the heat dissipation effect.

[0054] In practical implementation, the inlet 224 and outlet 225 of the heat dissipation channel 223 can be connected to a circulating pump, and the coolant can be water. Water can be filled into the heat dissipation channel 223, thus forming a circulating water flow that continuously removes heat from the heat-conducting component 22. Optionally, the inlet 224 and outlet 225 of the heat dissipation channel 223 can be connected to the cooling water circuit of a laser or pulsed light source; no specific limitation is made here. Figure 1 as well as Figure 3 The dashed arrows in the image indicate the direction of water flow. Figure 3 This is a top view of a portion of the light window structure, used only to illustrate the flow direction of water in the heat dissipation channel 223.

[0055] In one embodiment of the present invention, such as Figure 1As shown, the light-transmitting component 1 includes a light-transmitting element 12 and a heat-insulating frame 13. The heat-conducting component 11 is provided with a first light-transmitting surface 113, a first peripheral side surface 112 and a contact surface 111. The first light-transmitting surface 113 and the contact surface 111 are arranged opposite to each other, and the first peripheral side surface 112 is located between the first light-transmitting surface 113 and the contact surface 111. The light-transmitting element 12 is provided with a second light-transmitting surface 121, a second peripheral side surface 122 and a light-incident surface 123. The second light-transmitting surface 121 and the light-incident surface 123 are arranged opposite to each other, and the second peripheral side surface is located between the second light-transmitting surface 121 and the light-incident surface 123 and is connected to the heat-conducting component 22. The heat-insulating frame 13 is connected to the first light-transmitting surface 113 and the second light-transmitting surface 121 respectively to enclose and form a sealed cavity 3.

[0056] In this embodiment, the cooling component 11 has a contact surface 111 for cooling the treatment area and a first peripheral side surface 112 for connecting the cooling component. The light-transmitting component 12 has an incident surface 123 for the incidence of therapeutic light such as laser or pulsed light. During laser treatment, the laser light enters the light-transmitting component 12 from the incident surface 123, then passes through the light-transmitting component 12 into the cooling component 11, and finally exits from the contact surface 111 of the cooling component 11, thus ensuring the laser light output effect. The cooling component is connected to the first peripheral side surface 112 of the cooling component 11 to cool the cooling component 11. The heat-conducting component 22 is connected to the cooling component, and at least part of the heat-conducting component 22 is connected to the incident surface 123 of the light-transmitting component 12 to prevent condensation from forming due to a decrease in the temperature of the light-transmitting component 12. The cooling component 11 and the light-transmitting component 12 are connected by the heat insulation frame 13 and enclosed to form a sealed cavity 3, so as to reduce the heat transfer efficiency between the cooling component 11 and the light-transmitting component 12, thereby improving the cooling effect of the cooling component 11 and the heat preservation effect of the light-transmitting component 12, reducing the energy consumption of the cooling component, and preventing the light-transmitting component 12 from cooling down and condensing.

[0057] In actual implementation, the cooling component 11 and the light-transmitting component 12 can be arranged in a columnar shape. Optionally, the cooling component 11 and the light-transmitting component 12 can be arranged in a quadrangular prism shape, with the first peripheral side 112 being the four sides of the cooling component 11. The cooling component 21 can be disposed on any one or more sides of the cooling component 11. Alternatively, both the cooling component 11 and the light-transmitting component 12 can be cylindrical.

[0058] Understandably, the first light-transmitting surface 113 of the cooling component 11 and the second light-transmitting surface 121 of the light-transmitting component 12 are arranged opposite to each other, and the heat insulation frame 13 is connected to both the first light-transmitting surface 113 and the second light-transmitting surface 121, so that the cooling component 11 and the light-transmitting component 12 are spaced apart. The emission path of the therapeutic light such as laser or pulsed light is from the light-incident surface 123 to the light-transmitting component 12 to the second light-transmitting surface 121 to the first light-transmitting surface 113 to the cooling component 11 to the contact surface 111, thus ensuring the light transmission effect of the light-transmitting component 1.

[0059] In actual implementation, a sealed cavity 3 is formed between the first light-transmitting surface 113 and the second light-transmitting surface 121 to avoid direct contact between the first light-transmitting surface 113 and the second light-transmitting surface 121 and the outside air, thereby reducing the possibility of condensation on the first light-transmitting surface 113 and the second light-transmitting surface 121.

[0060] Optionally, the second peripheral side 122 of the light-transmitting element 12 is connected to the first part 221, and the light-incident surface 123 of the light-transmitting element 12 is connected to the second part 222, so as to facilitate the positioning and installation of the light-transmitting element 12, increase the contact area between the light-transmitting element 12 and the heat-conducting element 22, thereby ensuring the heat transfer effect between the heat-conducting element 22 and the light-transmitting element 12, and further avoid the condensation on the light-incident surface 123 and the second light-transmitting surface 121 of the light-transmitting element 12 due to the temperature drop of the light-transmitting element 12.

[0061] In actual implementation, the second peripheral side 122 of the light-transmitting element 12 is in close contact with the first part 221, the light-incident surface 123 of the light-transmitting element 12 is in close contact with the second part 222, and the light-transmitting element 12 and the heat-conducting element 22 can be bonded together with a high thermal conductivity adhesive.

[0062] In one embodiment of the present invention, such as Figure 1 As shown, the heat insulation frame 13 is arranged along the periphery of the first light-transmitting surface 113, and / or, the heat insulation frame 13 is arranged along the periphery of the second light-transmitting surface 121.

[0063] In this embodiment, the heat insulation frame 13 is arranged along the periphery of the first light-transmitting surface 113 or the second light-transmitting surface 121, thereby avoiding interference of the heat insulation frame 13 with the light-transmitting components. At the same time, the cross-sectional area of ​​the sealed cavity 3 is maximized, so that the first light-transmitting surface 113 and the second light-transmitting surface 121 are located within the sealed cavity 3, so as to further reduce the heat transfer efficiency of the cooling component 11 and the light-transmitting component 12, and keep the temperature of the cooling component 11 and the temperature of the light-transmitting component 12 in a relatively independent state.

[0064] In actual implementation, the first part 221 of the cooling component 11 and the heat-conducting component 22 are spaced apart, while the light-transmitting component 12 can be abutted against the first part 221 of the heat-conducting component 22. Thus, when the cooling component 11 and the light-transmitting component 12 are coaxially arranged, the heat insulation frame 13 can overlap with the light-transmitting component 12. At least part of the heat insulation frame 13 overlaps with the cooling component 11 to ensure the sealing of the sealed cavity 3.

[0065] In one embodiment of the present invention, the heat insulation frame 13 is made of aerogel. In this embodiment, the heat insulation frame 13 is made of aerogel, which has a certain elasticity to facilitate pressure sealing between the cooling component 11 and the heat insulation frame 13, and between the light-transmitting component 12 and the heat insulation frame 13, thereby improving the airtightness of the sealed cavity 3.

[0066] In one embodiment of the present invention, the sealed cavity 3 is filled with a dry gas or is set to a vacuum. In this embodiment, the sealed cavity 3 may be filled with a dry gas such as nitrogen or set to a vacuum to ensure that there is no moisture in the sealed cavity, so that even if the temperature of the first light-transmitting surface 113 and the second light-transmitting surface 121 decreases, no condensation will occur.

[0067] In one embodiment of the present invention, such as Figure 1 As shown, the contact surface 111 is coated with an antireflective film 4 and a hydrophilic film 5, with the hydrophilic film 5 located on the side of the antireflective film 4 facing away from the contact surface 111.

[0068] In this embodiment, the contact surface 111 is provided with an antireflective film 4 to increase light transmittance and reduce interfacial light loss, ensuring that the light transmittance is not less than 98%. When the light window assembly is used in a scenario with high air humidity, the antireflective film 4 on the contact surface 111 can be coated according to the refractive index of water to further reduce interfacial reflection caused by the water film. In addition to the antireflective film 4, the contact surface 111 is coated with a hydrophilic film 5 to reduce the surface tension of the contact surface 111, allowing the water vapor condensed on the contact surface 111 to quickly spread out and form a flat water film without forming a fog surface caused by tiny droplets, thereby reducing interference with light transmission.

[0069] In practical implementation, the light-incident surface 123, the first light-transmitting surface 113, and the second light-transmitting surface 121 are also coated with antireflective films 4 to reduce interfacial light loss and increase light transmittance, thereby ensuring the light transmission effect of the light-transmitting component 1. The light-transmitting films on the light-incident surface 123, the first light-transmitting surface 113, and the second light-transmitting surface 121 can be coated according to the refractive index of air. It is understandable that the antireflective film 4 is set to correspond to the wavelength of the transmitted light.

[0070] In one embodiment of the present invention, such as Figure 1 As shown, the materials of the cooling component 11 and the light-transmitting component 12 are sapphire glass, high thermal conductivity transparent ceramic, or high thermal conductivity transparent crystal; and / or, the sealing method of the cooling component 11 and the heat insulation frame 13 is pressure sealing; and / or, the sealing method of the light-transmitting component 12 and the heat insulation frame 13 is pressure sealing.

[0071] In this embodiment, the cooling component 11 and the light-transmitting component 12 can be sapphire glass, high thermal conductivity transparent ceramic, or high thermal conductivity transparent crystal to ensure that the cooling component 11 and the light-transmitting component 12 have good thermal conductivity and light transmittance, thereby improving the cooling efficiency of the cooling component on the cooling component 11.

[0072] The heat insulation frame 13 is made of aerogel, thus providing excellent heat insulation performance to reduce the heat transfer efficiency between the cooling component 11 and the light-transmitting component 12, thereby preventing the temperature of the light-transmitting component 12 from dropping. Pressure seals are provided between the cooling component 11 and the heat insulation frame 13, and between the light-transmitting component 12 and the heat insulation frame 13, to ensure a tight seal between them.

[0073] In practical implementation, the heat insulation frame 13 can also be made of materials with extremely low thermal conductivity, such as asbestos or rock wool, without specific limitations. The contact surface 111 of the cooling component 11, the light-incident surface 123 of the first light-transmitting surface 113, and the second light-transmitting surface 121 can be treated with ultra-smooth surface treatment processes such as high-precision polishing to improve the light transmission effect of the light-transmitting component 1. When the cooling component 11 and the light-transmitting component 12 are high thermal conductivity transparent crystals, the direction of their crystal axes is set parallel to the direction of the incident light.

[0074] Reference Figure 1 In one specific embodiment, the laser beam enters from the incident surface 123 along the straight arrow, and passes sequentially through the antireflective film (not shown in the figure) above the light-transmitting element 12, the light-transmitting element 12, the antireflective film 4 below the light-transmitting element 12, the sealed cavity 3, the first light-transmitting surface 113, the antireflective film (not shown in the figure) above the cooling element 11, the cooling element 11, the antireflective film 4 below the cooling element 11, and the hydrophilic film 5, before passing through the contact surface 111 to reach the skin. Since both the light-transmitting element 12 and the cooling element 11 are provided with antireflective films 4, the transmittance of the laser can be increased, and the amount of laser energy left on the light-transmitting element 12 and the cooling element 11 can be reduced, thus preventing the temperature of the light-transmitting element 11 and the cooling element 11 from rising too much. Then, the cooling element 21 works, and the cooling surface of the cooling element 21 cools down, transferring the cold air to the cooling element 11 that is in contact with it. The cooling element 11 then transfers the cold air to the contact surface 111 that is in indirect contact with it, thereby reducing the temperature of the skin.
