Description

Technical Field

[0001] The present invention relates to the field of rehabilitation treatment equipment, and more specifically, to a laser therapeutic apparatus for treating muscle and joint pain. Background Art

[0002] Due to the long-term sedentary work, staying up late, using electronic products and maintaining abnormal postures of modern people, muscle pain, stiffness, muscle shortening and reduced elasticity of fascia tissue are caused, which will lead to the degeneration and pain of muscles and joints.

[0003] The treatment of muscle and joint pain mainly includes oral medications and rehabilitation treatment. Limited by the current number of rehabilitation therapists in China, physical therapy and rehabilitation are difficult to be widely popularized; long-term oral medications will bring some side effects; the therapeutic effect of applying plasters externally is limited, and physical factors such as electrotherapy and magnetotherapy are affected by local tissues more, while phototherapy such as laser has no special requirements for local tissues, and there are no restrictions such as implants, stents, and pacemakers. Therefore, a portable and practical laser therapeutic apparatus has emerged on the market.

[0004] However, since the laser of the laser therapeutic apparatus concentrates a large amount of energy in a small area, this high energy density can quickly heat the skin and tissues, thereby causing thermal damage and tiny damage reactions of the skin and tissues, and these reactions will cause pain and discomfort. Therefore, the existing patent (a Chinese invention patent with the publication number of CN104587610A) discloses a laser treatment auxiliary device that can quickly cool the skin. By arranging spray heads and wire spraying ports on the inner ring of the heat dissipation and cooling device, the skin is cooled by spraying spray and heat dissipation wires, and the pain and discomfort are relieved;

[0005] However, since the light beam forming component device is arranged at the center position of the device, and the spray heads and wire spraying ports are arranged around the light beam forming component device, when the light beam forming component device irradiates the skin with laser, the spray heads and wire spraying ports cannot cool the skin being irradiated with laser. Only after the laser irradiation treatment is completed and the overall position of the device is moved to move the skin irradiated with laser away from below the light beam forming component device can the skin be cooled. Therefore, the existing laser therapeutic apparatus cannot cool the skin being irradiated with laser and relieve discomfort, and cannot relieve the pain and discomfort during the treatment in a timely manner. Summary of the Invention

[0006] Aiming at the problem in the prior art that the blanking device cannot be adjusted according to the blanking requirements of steel bars with different length specifications and can only realize the blanking of steel bars with a fixed length, the purpose of the present invention is to provide a laser therapeutic apparatus for treating muscle and joint pain.

[0012] Optionally, a temperature sensor is fixedly connected to the inner wall of the housing, and the temperature sensor is linearly connected to the circuit board.

[0013] Optionally, the driving component includes two synchronous wheels symmetrically and rotatably connected inside the housing, two synchronous belts symmetrically sleeved outside the two synchronous wheels, a plurality of support rollers rotatably connected inside the housing for supporting and guiding the synchronous belts, a motor fixedly connected to one side of the housing and with an output shaft passing through the housing and fixedly connected to one of the synchronous wheels, two activity grooves three symmetrically provided inside the housing and communicating with the activity cavity, and two connecting blocks symmetrically fixedly connected to both sides of the scraping block. The other ends of the two connecting blocks pass through the two activity grooves three and are respectively connected to the two synchronous belts.

[0014] Optionally, an active slot four and two symmetrically arranged active slots five connected to the active slot four are provided inside the scraping block, and a moisture removal component is connected inside the scraping block. The moisture removal component includes an active seat movably connected in the active slot four, two extension ends fixed on both sides of the active seat, and an eccentric block rotatably connected inside the active slot four. Guide rods are fixedly connected to the inner walls of the two active slots five, and the two extension ends are movably sleeved outside the guide rods. A second spring is sleeved outside the guide rod, and both ends of the second spring are connected to the inner wall of the active slot five and one side of the extension end respectively. Two gears are symmetrically and rotatably connected to both sides of the scraping block, and a connecting shaft is fixed on one side of each of the two gears. The other ends of the two connecting shafts penetrate the scraping block and enter the active slot four and are respectively connected to both ends of the eccentric block.

[0015] Optionally, one end of the active seat penetrates the scraping block and extends outward.

[0016] Optionally, a glue application part is connected inside the active seat, and the glue application part includes a mounting slot opened inside the active seat, a box body clamped in the mounting slot, an inner cavity opened in the box body, a cover plate screwed on one side of the box body, and a running bead rotatably connected inside the cover plate.

[0017] Optionally, a fan is fixed on one side of each of the two sliding plates, and a rubber air guide port is fixed on the other side of the two sliding plates. The rubber air guide port is movably inserted into the active slot one, and the air outlet of the fan faces the rubber air guide port.

[0018] Optionally, a control end is fixed on the outer surface of the shell, and the control end is linearly connected to the circuit board.

[0019] The technical solution provided by the present invention has at least the following beneficial effects compared with the prior art:

[0020] In the above solution, by movably arranging the laser generating part in the active cavity of the shell, when the driving component drives the scraping block to move, the scraping block can push the laser generating part to move and thus lift the laser generating part. In this way, while the laser generating part works to perform laser irradiation on the skin, the atomizing nozzle on the scraping block can also spray on the skin irradiated by the laser, cooling the skin to relieve discomfort, and being able to timely relieve the pain and discomfort of the skin irradiated by the laser during the treatment process. Moreover, the scraping block can also scrape the moisture on the skin evenly, helping to evenly distribute the sprayed cooling liquid, enabling the cooling liquid to better cover the skin surface, avoiding overcooling or insufficient cooling in local areas, and scraping off the excess moisture through the scraping plate, which can prevent the moisture from accumulating on the skin and affecting the penetrability and effect of the laser.

[0021] By arranging a moisture removal component inside the scraping block, when the driving component drives the scraping block to move, the eccentric block can push the movable seat to extend out of the scraping block. The cooperation of the second spring and the eccentric block enables the movable seat to perform telescopic movement inside the scraping block. When the movable seat reciprocates and telescopes inside the scraping block, it contacts the skin, forming a tiny air flow on the skin surface. This air flow can carry away the moist air on the skin surface, accelerating the evaporation of moisture, helping to increase the air flow on the skin surface, thereby accelerating the evaporation process of skin moisture. The evaporation of moisture will absorb a large amount of heat, further reducing the temperature of the skin surface, significantly reducing the burning sensation and discomfort during laser treatment, improving the comfort of the patient. At the same time, the contact between the movable seat and the skin can also pat and massage the skin, promoting the microcirculation and blood flow of the skin, helping to relieve pain and discomfort, and enhancing the user experience of the patient.

[0022] By arranging two fans on two symmetrical sliding plates, the fans blow the external gas into the movable cavity through the rubber air guide port, accelerating the air flow in the movable cavity. When the wind enters the movable cavity and blows on the skin, it can help the skin dissipate heat, dry the skin after being treated by the spray and moisture removal component. At the same time, the gas flow in the movable cavity can provide fresh air, increasing the oxygen supply on the skin surface, promoting the metabolism and regeneration of skin cells, helping the recovery after treatment, and keeping the skin fresh and dry.

[0047] As Figures 1 to 15 shown, an embodiment of the present invention provides a laser therapeutic apparatus for treating muscle and joint pain, including a housing 1, a laser generating part 2 connected inside the housing 1, a circuit board 18 and a power supply 19 fixedly connected inside the housing 1 (the power supply 19 is a rechargeable lithium-ion battery, which necessarily is equipped with a charging interface and a conversion circuit module, and the charging interface is provided on the outer surface of the housing 1, all of which belong to mature technologies and are also conventional settings, and will not be elaborated here). An activity cavity 14 is opened inside the housing 1, and the laser generating part 2 is movably connected in the activity cavity 14. A scraping block 3 is also movably connected to the inner wall of the activity cavity 14, and a driving assembly 6 for driving the scraping block 3 to move is arranged inside the housing 1. Two sliding grooves 12 and two first activity grooves 13 communicating with the activity cavity 14 are symmetrically opened on both sides of the housing 1, and two sliding plates 51 are respectively slidably connected in the two sliding grooves 12. A liquid supply part 52 is connected to one side of one of the sliding plates 51.

[0048] The liquid supply part 52 includes a housing 521 fixedly connected to one side of the sliding plate 51, a liquid storage box 522 fixedly connected to one side of the sliding plate 51 and located inside the housing 521 (the liquid storage box 522 has a heat preservation effect similar to that of a thermos cup), and a micro water pump 523. The input end of the micro water pump 523 is connected to the output end of the liquid storage box 522. An atomizing nozzle 53 is fixedly connected to one side of the scraping block 3, and connecting columns 54 are fixedly connected to both ends of the atomizing nozzle 53. The other ends of the two connecting columns 54 respectively pass through the two first activity grooves 13 and are fixedly connected to one side of the two sliding plates 51. The connecting columns 54 can move in the first activity grooves 13, and a through groove communicating with the input end of the atomizing nozzle 53 is opened inside one of the connecting columns 54. The output end of the micro water pump 523 is connected to the through groove.

[0049] The driving component 6 includes two synchronous pulleys 61 symmetrically and rotatably connected inside the housing 1, two synchronous belts 64 symmetrically sleeved outside the two synchronous pulleys 61, a plurality of support rollers 65 rotatably connected inside the housing 1 for supporting and guiding the synchronous belt 64, a motor 63 fixedly connected to one side of the housing 1 and having an output shaft passing through the housing 1 and fixedly connected to one of the synchronous pulleys 61, two moving grooves three 62 symmetrically formed inside the housing 1 and communicating with the moving cavity 14, and two connecting blocks 66 symmetrically fixedly connected to both sides of the scraping block 3. The other ends of the two connecting blocks 66 pass through the two moving grooves three 62 and are respectively connected to the two synchronous belts 64.

[0050] A control end 11 is fixedly connected to the outer surface of the housing 1 (the control end 11 is a touchable display screen. Under the initial set basic treatment instructions, other treatment parameters such as treatment time, intensity, mode, etc. can be manually modified through the touchable display screen), and the control end 11 is linearly connected to the circuit board 18 (the circuit board 18 is a PCB board integrated with a processing chip and has a wireless module, which belongs to mature prior art and will not be elaborated here. It should be noted that the circuit board 18 controls the micro water pump 523 through the wireless module, and the circuit board 18 is also linearly connected to the power supply 19, the laser generating part 2, and the motor 63).

[0051] By adopting the above technical solution, the inner arc surface of the housing 1 is covered on the skin, the laser generating part 2 is controlled to work, and the laser generating part 2 emits infrared light with a wavelength of 808 nm to irradiate the skin. After irradiating for a certain time, the motor 63 works to drive one of the synchronous pulleys 61 to rotate, and the synchronous pulley 61 drives the two synchronous belts 64 and the other synchronous pulley 61 to rotate, thereby driving the connecting block 66 and the scraping block 3 connected to the synchronous belt 64 to move. The connecting block 66 moves along the moving groove three 62, as Figure 12As shown in the figure, chamfers are provided on the outer surfaces of both the scraping block 3 and the laser generating part 2. When the scraping block 3 moves, the chamfer of the scraping block 3 contacts first before the chamfer of the laser generating part 2, enabling the scraping block 3 to push the laser generating part 2 to move into the interior of the movable cavity 14, increasing the distance between the laser generating part 2 and the skin. At this time, one side of the scraping block 3 can contact the skin, and the other side of the scraping block 3 contacts one side of the laser generating part 2 (the side of the laser generating part 2 adjacent to the skin). The micro water pump 523 pumps the coolant in the liquid storage box 522 into the through groove in one of the connecting columns 54 and enters the atomizing nozzle 53 from the through groove. The atomizing nozzle 53 atomizes and sprays the coolant onto the skin being irradiated by the laser. The movement of the scraping block 3 drives the atomizing nozzle 53, the connecting column 54, and the sliding plate 51 to move. The connecting column 54 moves in the first movable groove 13, and the sliding plate 51 slides along the sliding groove 12, realizing spray cooling of the skin at multiple parts, relieving discomfort. At the same time, the scraping block 3 can also scrape the moisture sprayed on the skin evenly, helping to distribute the spray coolant evenly, enabling the coolant to better cover the skin surface, avoiding overcooling or insufficient cooling in local areas. The excess moisture is scraped off by the scraping plate, which can prevent the moisture from accumulating on the skin and affecting the penetrability and effect of the laser.

[0052] As Figures 2 to 4 shown, the laser generating part 2 includes a transparent sleeve 21, a semiconductor laser emitter 22 fixedly connected inside the transparent sleeve 21, and a plurality of heat sinks 23. One ends of the plurality of heat sinks 23 contact one side of the semiconductor laser emitter 22. Extension plates 24 are integrally formed on both sides of the transparent sleeve 21, and guide grooves 25 are provided inside the extension plates 24.

[0053] On the inner wall of the movable cavity 14, a second movable groove 15 for accommodating the movement of the extension plate 24 is provided, and a guide post 16 is fixedly connected to the inner wall of the second movable groove 15. The guide post 16 is inserted into the guide groove 25, and a first spring 17 is sleeved outside the guide post 16. Both ends of the first spring 17 are connected to the inner wall of the second movable groove 15 and one side of the extension plate 24 respectively.

[0054] By adopting the above technical solution, the transparent sleeve 21 can protect the semiconductor laser emitter 22 from direct contact with the scraping block 3. When one side of the scraping block 3 contacts the outer surface of one side of the transparent sleeve 21, the scraping block 3 pushes the transparent sleeve 21 and the extension plate 24 to move. The extension plate 24 moves in the second movable groove 15 towards the direction of the first spring 17, compressing the first spring 17, and increasing the distance between the transparent sleeve 21 and the skin. When the scraping block 3 separates from the transparent sleeve 21, the first spring 17 can push the extension plate 24 and the transparent sleeve 21 to reset, reducing the distance between the transparent sleeve 21 and the skin. The heat sinks 23 are used to reduce the operating temperature of the semiconductor laser emitter 22 and prevent the semiconductor laser emitter 22 from overheating during operation.

[0055] As Figure 1 shown, a temperature sensor 4 is fixedly connected to the inner wall of the housing 1, and the temperature sensor 4 is linearly connected to the circuit board 18.

[0056] By adopting the above technical solution, the temperature sensor 4 belongs to mature prior art and is used in this application to contact the skin and detect the skin temperature. According to the skin temperature detected by the temperature sensor 4, the circuit board 18 controls the water supply amount of the micro water pump 523 to the atomizing nozzle 53. When the skin temperature is relatively high, the micro water pump 523 increases the water supply amount to the atomizing nozzle 53. When the skin temperature is relatively low, the water supply amount to the atomizing nozzle 53 is reduced, so that the atomizing nozzle 53 of this application can be adaptively adjusted.

[0057] As Figure 6 、 Figure 10 、 Figures 13 - 15 shown, an activity groove four 71 and two symmetrically arranged activity grooves five 74 connected to the activity groove four 71 are formed inside the scraping block 3, and a moisture removing component 7 is connected inside the scraping block 3. The moisture removing component 7 includes a movable seat 72 movably connected in the activity groove four 71, two extension ends 76 fixedly connected to both sides of the movable seat 72, and an eccentric block 73 rotatably connected inside the activity groove four 71. Guide rods 77 are fixedly connected to the inner walls of the two activity grooves five 74, and the two extension ends 76 are movably sleeved outside the guide rods 77. A second spring 78 is sleeved outside the guide rod 77, and both ends of the second spring 78 are respectively connected to the inner wall of the activity groove five 74 and one side of the extension end 76. Two gears 75 are symmetrically rotatably connected to both sides of the scraping block 3, and a connecting shaft is fixedly connected to one side of each of the two gears 75. The other ends of the two connecting shafts penetrate through the scraping block 3 and enter the activity groove four 71 and are respectively connected to both ends of the eccentric block 73. One end of the movable seat 72 penetrates through the scraping block 3 and extends outwards.

[0058] By adopting the above technical solution, when the scraping block 3 moves in the movable cavity 14, the gear 75 moves in the tooth groove 79. The tooth groove 79 drives the gear 75 to rotate. The rotation of the gear 75 drives the eccentric block 73 to rotate. When the eccentric block 73 rotates, the irregular eccentric end can push the movable seat 72 to move towards the skin direction, compressing the second spring 78. When the irregular eccentric end of the eccentric block 73 separates from the movable seat 72, the second spring 78 pushes the movable seat 72 to retract into the scraping block 3. The rotation of the eccentric block 73 drives the movable seat 72 to reciprocate in the fourth movable groove 71. The movable seat 72 contacts the skin, forming a tiny air flow on the skin surface. This air flow can take away the moist air on the skin surface, accelerating the evaporation of moisture, helping to increase the air flow on the skin surface, thereby accelerating the evaporation process of skin moisture. The evaporation of moisture will absorb a large amount of heat, further reducing the skin surface temperature, significantly reducing the burning sensation and discomfort during laser treatment, improving the comfort of the patient. At the same time, the contact between the movable seat 72 and the skin can also pat and massage the skin, promoting the microcirculation and blood flow of the skin, helping to relieve pain and discomfort, and enhancing the patient's usage experience.

[0059] As Figure 11 shown, a glue application part 8 is connected inside the movable seat 72. The glue application part 8 includes a mounting groove 81 opened inside the movable seat 72, a box body 82 clamped in the mounting groove 81, an inner cavity body 83 opened in the box body 82, a cover plate 84 screwed on one side of the box body 82, and a ball 85 rotatably connected inside the cover plate 84. There is a gap between the ball 85 and the cover plate 84 for the liquid in the inner cavity body 83 to flow out.

[0060] By adopting the above technical solution, a protective gel is stored inside the inner cavity body 83. When the movable seat 72 reciprocates in the scraping block 3, it can make the protective gel move in the inner cavity body 83. The protective gel flows onto the outer surface of the ball 85. Since the movable seat 72 can contact the skin, the ball 85 will also contact the skin. When the ball 85 contacts the skin and the scraping block 3 moves, the ball 85 can rotate inside the cover plate 84, thereby taking out the protective gel in the inner cavity body 83. The gel on the outer surface of the ball 85 can be smeared on the skin, which can reduce the direct stimulation of the laser on the skin, protect the skin from excessive heat damage, help relieve pain and discomfort, and can also provide additional moisturizing and nourishing effects, helping to improve the skin quality and promote healing. The ball 85 also belongs to the prior art. For example, the ball products applied to the armpit for freshness in the prior art. The working principle of the ball in this application is the same as that of it.

[0061] As Figure 1 and Figure 7As shown in the figure, a fan 9 is fixedly connected to one side of each of the two skateboards 51, and a rubber air guide port 10 is fixedly connected to the other side of each of the two skateboards 51. The rubber air guide port 10 is movably inserted into the first movable groove 13, and the air outlet of the fan 9 faces the rubber air guide port 10.

[0062] By adopting the above technical solution, the fan 9 blows the external gas into the movable cavity 14 through the rubber air guide port 10, accelerating the air flow in the movable cavity 14. When the wind enters the movable cavity 14 and blows on the skin, it can help the skin dissipate heat and dry the skin after being treated by the spray and moisture removal component 7. At the same time, the gas flow in the movable cavity 14 can provide fresh air, increase the oxygen supply on the skin surface, promote the metabolism and regeneration of skin cells, contribute to the recovery after treatment, and keep the skin fresh and dry.

[0063] The working process of the technical solution provided by the present invention is as follows:

[0064] Place the inner arc surface of the housing 1 on the skin, control the laser generating part 2 to work and irradiate the skin. After irradiating for a certain period of time, the driving component 6 drives the scraping block 3 to move. When one side of the scraping block 3 contacts the outer surface of one side of the transparent sleeve 21, the scraping block 3 pushes the transparent sleeve 21 and the extension plate 24 to move. The extension plate 24 moves in the second movable groove 15 towards the direction of the first spring 17, compressing the first spring 17, and increasing the distance between the transparent sleeve 21 and the skin. At this time, one side of the scraping block 3 can contact the skin. The micro water pump 523 pumps the coolant in the liquid storage box 522 into the through groove in one of the connecting columns 54, and enters the atomizing nozzle 53 from the through groove. The atomizing nozzle 53 atomizes and sprays the coolant on the skin being irradiated by the laser. When the scraping block 3 moves in the movable cavity 14, the gear 75 moves in the tooth groove 79. The tooth groove 79 drives the gear 75 to rotate. The rotation of the gear 75 drives the eccentric block 73 to rotate. When the irregular eccentric end of the eccentric block 73 rotates, it can push the movable seat 72 towards the skin direction, compressing the second spring 78. When the irregular eccentric end of the eccentric block 73 separates from the movable seat 72, the second spring 78 pushes the movable seat 72 to retract into the scraping block 3. The rotation of the eccentric block 73 drives the movable seat 72 to reciprocate in the fourth movable groove 71. The movable seat 72 contacts the skin, forming a tiny air flow on the skin surface. This air flow can take away the wet air on the skin surface and accelerate the evaporation of moisture. When the movable seat 72 reciprocates in the scraping block 3, at the same time, the running bead 85 contacts the skin. The running bead 85 contacts the skin and the scraping block 3 moves simultaneously, enabling the running bead 85 to rotate in the cover plate 84, thereby taking out the protective gel in the inner cavity body 83. The gel on the outer surface of the running bead 85 can be smeared on the skin, which can reduce the direct stimulation of the laser on the skin. The fan 9 blows the external gas into the movable cavity 14 through the rubber air duct 10, accelerating the air flow in the movable cavity 14. When the wind enters the movable cavity 14 and blows on the skin, it can help the skin dissipate heat and dry the skin after being treated by the spraying and moisture removing component 7.
