Description

Technical Field

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

[0002] Because modern people work at desks for long periods of time, stay up late to work, use electronic products and have abnormal postures for a long time, they suffer from muscle pain, stiffness, muscle shortening and reduced elasticity of fascia tissue, which can lead to muscle and joint degeneration and pain.

[0003] The treatment for muscle and joint pain mainly includes oral medications and rehabilitation therapy. Due to the current limited number of rehabilitation therapists in my country, physical therapy and rehabilitation are difficult to be widely popularized; long-term oral medications will bring some side effects; the therapeutic effect of external plasters is limited, and physical factors such as electrotherapy and magnetic therapy are more affected by local tissue factors, while light therapy such as laser has no special requirements for local tissues, and is not restricted by implants, stents, pacemakers, etc. Therefore, portable and practical laser therapy devices have appeared on the market.

[0004] However, since the laser of the laser therapy device 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 to the skin and tissues and minor damage reactions, which can cause pain and discomfort. Therefore, the existing patent (Chinese invention patent with publication number CN104587610A) discloses a laser therapy auxiliary device that can quickly cool the skin. By arranging a spray head and a spinneret on the inner ring of the heat dissipation cooling device, the skin is cooled by spraying spray and heat dissipation wire to relieve pain and discomfort.

[0005] However, since the beam forming component device is arranged at the center of the device, and the spray head and the spinneret are arranged around the beam forming component device, when the beam forming component device irradiates the skin with laser, the spray head and the spinneret are unable to cool down the skin undergoing laser irradiation treatment. Only after the laser irradiation treatment is completed and the overall position of the device is moved so that the skin undergoing laser irradiation treatment is moved away from under the beam forming component device, can the skin be cooled down. Therefore, the existing laser therapy device cannot cool down the skin undergoing laser irradiation and relieve discomfort, and cannot promptly relieve pain and discomfort during the treatment process. Summary of the invention

[0013] Optionally, the driving assembly includes two synchronous wheels symmetrically rotatably connected inside the shell, two synchronous belts symmetrically sleeved on the outside of the two synchronous wheels, a plurality of support rollers rotatably connected inside the shell for supporting and guiding the synchronous belts, a motor fixed to one side of the shell and with an output shaft passing through the shell and fixed to one of the synchronous wheels, two active grooves three symmetrically opened inside the shell and connected to the active cavity, two connecting blocks symmetrically fixed on both sides of the scraper block, and the other ends of the two connecting blocks pass through the two active grooves three and are respectively connected to the two synchronous belts.

[0014] Optionally, a movable groove four and two movable grooves five symmetrically arranged and connected to the movable groove four are opened inside the scraper block, and a moisture removal component is connected to the inside of the scraper block, the moisture removal component includes a movable seat movably connected in the movable groove four, two extension ends fixedly connected to both sides of the movable seat, and an eccentric block rotatably connected to the inside of the movable groove four, the inner walls of the two movable grooves five are fixedly connected to guide rods, and the two extension ends are movably sleeved on the outside of the guide rods, a spring two is sleeved on the outside of the guide rods, and the two ends of the spring two are respectively connected to the inner wall of the movable groove five and one side of the extension end, two gears are symmetrically rotatably connected on both sides of the scraper block, and one side of the two gears is fixedly connected to a connecting shaft, and the other ends of the two connecting shafts pass through the scraper block into the movable groove four and are respectively connected to the two ends of the eccentric block.

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

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

[0020] In the above scheme, by movably setting the laser generating part in the movable cavity of the shell, when the driving component drives the scraper block to move, the scraper block can push the laser generating part to move and thus lift the laser generating part. In this way, while the laser generating part is working to irradiate the skin with laser, the atomizing nozzle on the scraper block can also spray onto the skin irradiated by the laser, so as to cool the skin and relieve discomfort. The pain and discomfort of the skin irradiated by the laser during the treatment process can be relieved in time. The scraper block can also scrape the moisture on the skin, help to evenly distribute the sprayed coolant, so that the coolant can better cover the skin surface, avoid overcooling or insufficient cooling of local areas, and scrape away excess moisture through the scraper to avoid moisture accumulation on the skin affecting the penetration and effect of the laser.

[0021] By arranging a moisture removal component inside the scraper block, when the driving component drives the scraper block to move, the eccentric block can push the movable seat to extend out of the scraper block, and the spring 2 and the eccentric block cooperate to enable the movable seat to perform telescopic movement inside the scraper block. When the movable seat reciprocates and telescopes inside the scraper block, the movable seat contacts the skin, forming a tiny air flow on the skin surface. This airflow can take away the moist air on the skin surface and accelerate the evaporation of moisture. It can help increase the airflow on the skin surface, thereby accelerating the evaporation process of skin moisture. The evaporation of moisture will absorb a large amount of heat, thereby further reducing the temperature of the skin surface, which can significantly reduce the burning sensation and discomfort during laser treatment and improve the patient's comfort. At the same time, the movable seat in contact with the skin can also pat and massage the skin, promote skin microcirculation and blood flow, help reduce pain and discomfort, and enhance the patient's user experience.

[0022] By arranging two fans on two symmetrical slides, the fans blow external gas into the active cavity through rubber air guide ports, thereby accelerating the flow of air in the active cavity. When the wind enters the active cavity 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 components. At the same time, the gas flow in the active cavity can provide fresh air, increase the oxygen supply on the skin surface, promote the metabolism and regeneration of skin cells, help recovery after treatment, and keep the skin fresh and dry.

[0047] like Figures 1 to 15 As shown, an embodiment of the present invention provides a laser therapeutic device for treating muscle and joint pain, including a shell 1, a laser generating unit 2 connected to the inside of the shell 1, a circuit board 18 and a power supply 19 fixed to the inside of the shell 1 (the power supply 19 is a rechargeable lithium-ion battery, which must be equipped with a charging interface and a conversion circuit module. The charging interface is arranged on the outer surface of the shell 1, which belongs to mature technology and is also a conventional setting, and is not repeated here), an active cavity 14 is opened inside the shell 1, and the laser generating unit 2 is movably connected in the active cavity 14, a scraper block 3 is also movably connected to the inner wall of the active cavity 14, and a driving component 6 for driving the scraper block 3 to move is arranged inside the shell 1, two slide grooves 12 and two active grooves 13 connected to the active cavity 14 are symmetrically opened on both sides of the shell 1, and two slide plates 51 are slidably connected in the two slide grooves 12, respectively, and one side of the slide plate 51 is connected to a liquid supply part 52.

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

[0049] The driving assembly 6 includes two synchronous wheels 61 symmetrically rotatably connected inside the shell 1, two synchronous belts 64 symmetrically sleeved on the outside of the two synchronous wheels 61, a plurality of support rollers 65 rotatably connected inside the shell 1 for supporting and guiding the synchronous belts 64, a motor 63 fixedly connected to one side of the shell 1 and having an output shaft passing through the shell 1 and fixedly connected to one of the synchronous wheels 61, two active grooves three 62 symmetrically opened inside the shell 1 and connected to the active cavity 14, and two connecting blocks 66 symmetrically fixedly connected to both sides of the scraper block 3, and the other ends of the two connecting blocks 66 pass through the two active grooves three 62 and are respectively connected to the two synchronous belts 64.

[0050] A control terminal 11 is fixedly connected to the outer surface of the shell 1 (the control terminal 11 is a touch-screen display. Under the initially set basic treatment instructions, other treatment parameters, such as treatment time, intensity, mode, etc., can be manually modified through the touch-screen display), and the control terminal 11 is linearly connected to the circuit board 18 (the circuit board 18 is a PCB board with an integrated processing chip and a wireless module, which is a mature existing technology and will not be described 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 unit 2, and the motor 63).

[0051] By adopting the above technical solution, the inner arc surface of the shell 1 is covered on the skin, and the laser generating part 2 is controlled to work. The laser generating part 2 works to emit infrared light with a wavelength of 808nm to irradiate the skin. After irradiation for a certain period of time, the motor 63 works to drive one of the synchronous wheels 61 to rotate, and the synchronous wheel 61 drives the two synchronous belts 64 and the other synchronous wheel 61 to rotate, thereby driving the connecting block 66 connected to the synchronous belt 64 and the scraping block 3 to move, and the connecting block 66 moves along the movable groove 3 62, as shown in FIG. Fig.12As shown, the outer surface of the scraper block 3 and the outer surface of the laser generating part 2 are both provided with a chamfer. When the scraper block 3 moves, the chamfer of the scraper block 3 contacts the chamfer of the laser generating part 2 before the chamfer of the laser generating part 2, so that the scraper block 3 can push the laser generating part 2 to move inside the active cavity 14, so that the distance between the laser generating part 2 and the skin becomes larger. At this time, one side of the scraper block 3 can contact the skin, and the other side of the scraper 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 mist The atomizing nozzle 53 sprays the coolant on the skin undergoing laser irradiation, and the scraping block 3 moves to drive the atomizing nozzle 53, the connecting column 54 and the slide plate 51 to move. The connecting column 54 moves in the movable groove 13, and the slide plate 51 slides along the slide groove 12 to achieve spray cooling of the skin in multiple parts to relieve discomfort. At the same time, the scraping block 3 can also scrape the water sprayed on the skin to help evenly distribute the spray coolant so that the coolant can better cover the skin surface to avoid overcooling or insufficient cooling of local areas. The scraper can also scrape away excess water to avoid water accumulation on the skin that affects the penetration and effect of the laser.

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

[0053] The movable cavity 14 has an inner wall provided with an movable groove 15 for accommodating the movement of the extension plate 24, and a guide column 16 is fixedly connected to the inner wall of the movable groove 15. The guide column 16 is inserted in the guide groove 25, and a spring 17 is sleeved on the outside of the guide column 16. The two ends of the spring 17 are respectively connected to the inner wall of the movable groove 15 and one side of the extension plate 24.

[0054] By adopting the above technical scheme, the transparent sleeve 21 can protect the semiconductor laser emitter 22 to prevent the semiconductor laser emitter 22 from directly contacting the scraper block 3. When one side of the scraper block 3 contacts the outer surface of one side of the transparent sleeve 21, the scraper block 3 pushes the transparent sleeve 21 and the extension plate 24 to move, and the extension plate 24 moves in the movable groove 215 toward the direction of the spring 17, so that the spring 17 is compressed, and the distance between the transparent sleeve 21 and the skin becomes larger. When the scraper block 3 is separated from the transparent sleeve 21, the spring 17 can push the extension plate 24 and the transparent sleeve 21 to reset, and the distance between the transparent sleeve 21 and the skin becomes smaller. The heat sink 23 is used to reduce the operating temperature of the semiconductor laser emitter 22 to prevent the semiconductor laser emitter 22 from overheating during operation.

[0055] like Figure 1 As 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 a mature existing technology and is used in the present application to contact the skin and detect the temperature of the skin. According to the temperature of the skin detected by the temperature sensor 4, the circuit board 18 controls the micro water pump 523 to supply water to the atomizing nozzle 53. When the skin temperature is high, the micro water pump 523 increases the water supply to the atomizing nozzle 53. When the skin temperature is low, the water supply to the atomizing nozzle 53 is reduced, so that the atomizing nozzle 53 of the present application can be adaptively adjusted.

[0057] like Figure 6 , Fig.10 , Figure 13-Figure 15 As shown, the scraper block 3 is provided with a movable groove 41 and two movable grooves 54 74 symmetrically arranged and connected to the movable groove 41, and the scraper block 3 is connected with a moisture removal assembly 7, which includes a movable seat 72 movably connected to the movable groove 41, two extension ends 76 fixedly connected to both sides of the movable seat 72, and an eccentric block 73 rotatably connected to the movable groove 41. The inner walls of the two movable grooves 54 74 are fixedly connected with guide rods 77, and the two extension ends 76 are movably sleeved on the outside of the guide rods 77. The guide rods 77 are sleeved with springs 28 on the outside, and the two ends of the springs 28 are respectively connected to the inner wall of the movable groove 54 74 and one side of the extension ends 76. The scraper block 3 is symmetrically rotatably connected with two gears 75 on both sides, and one side of the two gears 75 is fixedly connected with a connecting shaft, and the other ends of the two connecting shafts penetrate the scraper block 3 into the movable groove 41 and are respectively connected to the two ends of the eccentric block 73. One end of the movable seat 72 penetrates the scraper block 3 and extends outward.

[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, and 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 toward the skin, so that the spring 2 78 is compressed. When the irregular eccentric end of the eccentric block 73 is separated from the movable seat 72, the spring 2 78 pushes the movable seat 72 to retract into the scraping block 3, and the eccentric block 73 rotates to drive the movable seat 72 to reciprocate in the movable groove 4 71, and the movable seat 72 is in contact with the skin. Contact with the skin forms a tiny air flow on the skin surface, which can take away the moist air on the skin surface and accelerate the evaporation of water. It can help increase the airflow on the skin surface, thereby accelerating the evaporation of skin water. The evaporation of water will absorb a large amount of heat, thereby further reducing the temperature of the skin surface, which can significantly reduce the burning sensation and discomfort during laser treatment and improve the patient's comfort. At the same time, the movable seat 72 can also pat and massage the skin when in contact with the skin, promote skin microcirculation and blood flow, help reduce pain and discomfort, and enhance the patient's experience.

[0059] like Fig.11 As shown, the movable seat 72 is internally connected to a glue coating portion 8, and the glue coating portion 8 includes a mounting groove 81 opened in the movable seat 72, a box body 82 clamped in the mounting groove 81, an inner cavity 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 to the inside of the cover plate 84, and there is a gap between the ball 85 and the cover plate 84 to facilitate the outflow of liquid in the inner cavity 83.

[0060] By adopting the above technical solution, the inner cavity 83 stores the protective gel. When the movable seat 72 reciprocates in the scraper block 3, the protective gel can be moved in the inner cavity 83, and the protective gel flows to the outer surface of the ball 85. Since the movable seat 72 can contact the skin, the ball 85 will also contact the skin. The ball 85 contacts the skin and the scraper block 3 moves at the same time, so that the ball 85 can rotate in the cover plate 84, thereby bringing out the protective gel in the inner cavity 83. The gel on the outer surface of the ball 85 can be applied to the skin, which can reduce the direct stimulation of the laser to the skin, protect the skin from excessive heat damage, help relieve pain and discomfort, and provide additional moisturizing and nourishing effects, which help improve skin quality and promote healing. The ball 85 also belongs to the prior art. For example, the ball product used for refreshing underarms in the prior art has the same working principle as the ball product in the present application.

[0061] like Figure 1 and Figure 7As shown, a fan 9 is fixedly connected to one side of the two slide plates 51 , and a rubber air guide port 10 is fixedly connected to the other side of the two slide plates 51 . The rubber air guide port 10 is movably inserted into a 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 external gas into the active cavity 14 through the rubber air guide port 10, thereby accelerating the flow of air in the active cavity 14. When the wind enters the active cavity 14 and blows on the skin, it can help the skin dissipate heat and dry the skin treated by the spray and moisture removal component 7. At the same time, the gas flow in the active cavity 14 can provide fresh air, increase the oxygen supply on the skin surface, promote the metabolism and regeneration of skin cells, help 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] The inner arc surface of the shell 1 is placed on the skin, and the laser generating part 2 is controlled to work to irradiate the skin. After a certain period of irradiation, the driving component 6 drives the scraper 3 to move. When one side of the scraper 3 contacts the outer surface of one side of the transparent sleeve 21, the scraper 3 pushes the transparent sleeve 21 and the extension plate 24 to move. The extension plate 24 moves in the movable groove 2 15 toward the direction of the spring 17, so that the spring 17 is compressed, and the distance between the transparent sleeve 21 and the skin becomes larger. At this time, one side of the scraper 3 can contact the skin, and the micro water pump 5 23 The coolant in the liquid storage box 522 is pumped 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 sprays the coolant on the skin being irradiated by laser. When the scraping block 3 moves in the movable chamber 14, the gear 75 moves in the tooth groove 79, and 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 toward the skin, so that the spring The movable seat 72 is compressed by the second 78. When the irregular eccentric end of the eccentric block 73 is separated from the movable seat 72, the spring second 78 pushes the movable seat 72 to retract into the scraping block 3. The eccentric block 73 rotates to drive the movable seat 72 to reciprocate in the movable groove four 71. The movable seat 72 contacts the skin, forming a small air flow on the skin surface. This air flow can take away the moist air on the skin surface and accelerate the evaporation of moisture. When the movable seat 72 reciprocates in the scraping block 3, the ball 85 contacts the skin at the same time. The ball 85 contacts the skin and the scraping block 3 moves at the same time, so that the ball 85 can rotate in the cover plate 84, thereby bringing out the protective gel in the inner cavity 83. The gel on the outer surface of the ball 85 can be applied to the skin, which can reduce the direct stimulation of the laser to the skin. The fan 9 blows the external gas into the active cavity 14 through the rubber air guide port 10 to accelerate the flow of air in the active cavity 14. When the wind enters the active cavity 14 and blows on the skin, it can help the skin dissipate heat and dry the skin treated by the spray and moisture removal component 7.
