Description

Technical Field

[0001] The present invention relates to the field of medical device technology, and in particular to a laser hair growth treatment helmet that integrates adaptive head circumference adjustment, real-time scalp temperature monitoring, and an efficient assembly structure, and is suitable for multi-patient scenarios in hair loss treatment institutions. Background Art

[0002] Laser hair growth helmets are Class II medical devices. Minoxidil tincture can enhance hair growth when used in conjunction with a laser hair growth device. Minoxidil tincture is a topical vasodilator that works by improving local blood circulation to hair follicles and prolonging their growth phase. It is commonly used clinically to treat androgenic alopecia. Laser hair growth devices primarily use low-energy lasers to stimulate hair follicle cell metabolism, improve the scalp microenvironment, and help slow the progression of hair loss. When used together, the medication can enhance nutrient supply to hair follicles, while physical therapy can increase follicle activity.

[0003] The existing laser hair growth treatment helmet has the following problems: 1. Existing laser hair growth helmets have adaptability defects. The rigid structure of the fixed head support pad results in a narrow head circumference adaptation range (only suitable for heads within the range of 54-58cm), which cannot cover the mainstream adult head circumference range of 51-65cm. Frequent manual adjustment or replacement of the head support pad accessories is required, significantly reducing the equipment turnover efficiency. 2. Existing laser hair growth helmets pose safety risks. Due to the lack of a temperature monitoring module, existing equipment cannot dynamically adjust the laser power. When the local temperature exceeds 40°C (the critical threshold for hair follicle damage), an inflammatory cascade reaction is triggered (TRPV1 activation → IL-6 / TNF-α release), and the risk of hair follicle miniaturization increases to 1.37 times that of the normal temperature exposure group, resulting in an 18% decrease in scalp blood flow, interrupting the nutrient supply to hair follicles, and accelerating the hair loss process. This violates the temperature control requirements of medical laser equipment safety standards (ISO 60601-2-22, GB9706.1-2007); 3. Existing laser hair growth helmets have low assembly efficiency. The split structure of the flexible circuit board has fixed holes and is fixed with pins, resulting in low assembly efficiency. In addition, the gap between the split structure of the flexible circuit board and the connection is large and cannot be adjusted, resulting in a smaller treatment area. 4. Existing laser hair growth helmets use a snap-on design for their outer shells. While this prevents exposed screws from affecting the product's aesthetics and sales, it also reduces overall structural stability after assembly. While screw connections offer a higher overall structure, the excessive number of exposed screws can negatively impact sales. Summary of the Invention

[0004] The technical problem to be solved by this invention is to provide a laser hair growth therapy helmet that integrates air pressure adaptive support, infrared temperature monitoring, and gapless FPC assembly. Simultaneously, these features achieve: a dynamic adaptability range of 50-65cm (compatible with 99% of adult head shapes); temperature monitoring accuracy of ±0.5°C and an overheat response time of <1s; a 30% increase in flexible circuit board assembly efficiency, a 10% increase in the effective treatment area (the gap between adjacent splits of the flexible circuit board after welding is ≤0.1mm); and a balanced outer shell connection strength and aesthetics (the laser hair growth therapy helmet has zero exposed screws).

[0034] The present invention is described in detail below in conjunction with specific embodiments: like Figures 1 to 17 The laser hair growth therapy helmet shown includes a middle shell 1, a top shell 2, a bottom shell 3, a touch display screen assembly 4, a laser lens protective cover 5, a charging connector 6, a vibration motor 7, a flexible circuit board 9 and a battery assembly. The battery assembly is fixed on the bottom shell 3, the top shell 2 and the bottom shell 3 are respectively fixedly installed on the bottom and top of the middle shell 1, and the laser lens protective cover 5 is fixedly installed on the bottom shell 2; the middle shell 1, the top shell 2 and the bottom shell 3 are assembled to form an outer shell.

[0035] The flexible circuit board 9 is provided with a laser treatment head, an infrared temperature sensor, and an infrared reflective sensor. The laser treatment head generates a signal for the user's hair growth treatment. The infrared temperature sensor monitors the user's scalp temperature and feeds back to the control main board 41. When the temperature is too high, the control main board 41 controls the laser treatment head to reduce the power. The infrared temperature sensor cooperates with the control main board 41 to monitor the accuracy of ±0.5°C and the overheat response time is <1s. The infrared reflective sensor uses the principle of infrared reflection to determine the presence of obstacles in front according to the intensity of the reflection. The control main board 41 can determine whether the helmet is in the head-wearing state through the signal fed back by the infrared reflective sensor circuit. When the user wears the laser hair growth treatment helmet When the helmet starts treatment, the control motherboard 41 starts treatment. When the user takes off the laser hair growth treatment helmet, the control motherboard 41 controls the helmet to pause treatment. The flexible circuit board 9 has a forked structure 91. A positioning column 52 is provided on the convex surface of the laser lens protective cover 5. The positioning column 52 has a threaded blind hole. The flexible circuit board 9 also has a positioning hole 93 that matches the positioning column 52. The flexible circuit board 9 is installed on the positioning column 52 through its positioning hole 93. The positioning column 52 is threaded with a screw for tightening and fixing the flexible circuit board 9; the flexible circuit board is sleeved on the positioning column of the laser lens protective cover and is prevented from falling off by screws. Its installation structure is simple and the assembly speed is fast, and the positioning support soft board is eliminated.

[0036] The touch screen assembly 4 is embedded in and fixedly installed in the through hole 11 at the front end of the middle shell 1. The touch screen assembly 4 has a control mainboard 41; The charging connector 6 and the vibration motor 7 are fixedly mounted on the rear end and the front end of the bottom shell 2 respectively; The charging connector 6, vibration motor 7, flexible circuit board 9, and battery assembly are respectively connected to the control main board 41 circuit of the touch display assembly 4. After the charging connector 6 is connected to the power supply, it charges the battery assembly, and the battery assembly supplies power to other electronic components of the laser hair growth therapy helmet. The laser hair growth therapy helmet has a wireless use function.

The second protrusion 20 is embedded in the first card slot, the first protrusion 10 is embedded in the second card slot, and the third protrusion 50 is embedded in the third card slot. By coordinating the protrusions and the card slots, the non-up and down degrees of freedom of the middle shell 1, top shell 2, bottom shell 3, and laser lens protective cover 5 can be restricted, which can not only improve the positioning speed of the middle shell 1, top shell 2, bottom shell 3, and laser lens protective cover 5 during assembly, but also improve the overall structural strength of the middle shell 1, top shell 2, bottom shell 3, and laser lens protective cover 5 after assembly.

[0038] A first connecting column 31 is provided on the inner side of the bottom shell 3, a support sleeve 32 is provided on the outer side of the bottom shell 3, a second connecting column 13 is provided on the middle shell 1, and a third connecting column 21 is provided on the top shell 2. Threaded holes are provided in the first connecting column 31 and the second connecting column 13. A notch 14 is provided on the top of the middle shell 1, and a circular ring 15 is integrally formed in the notch 14. The bottom edge of the laser lens protective cover 5 has an outwardly extending plane 53, and a countersunk hole is provided on the plane 53; by providing various connecting columns, the structural strength after screw connection can be improved.

[0039] The screws pass through the countersunk holes and are screwed onto the first connecting columns 31 to connect and fix the laser lens protective cover 5 to the bottom shell 3; the screws are hidden inside the helmet, which not only ensures the aesthetics of the helmet by not exposing the screws, but also improves the overall assembly structure strength compared to the snap-on installation method.

[0040] The screws pass through the ring 15 and are screwed to the third connecting column 21 to connect and fix the middle shell 1 and the top shell 2; the screws are hidden inside the helmet, which not only ensures the aesthetics of the helmet without exposing the screws (the number of exposed screws in the laser hair growth treatment helmet is 0), but also improves the overall assembly structure strength compared to the snap-on installation method.

[0041] The screw passes through the support sleeve 32 and is screwed to the second connecting column 13 to connect and fix the middle shell 1 and the bottom shell 3. The support sleeve 32 can increase the structural strength of the screw connection. At the same time, the support sleeve 32 can also support the second connecting column 13 to avoid the problem of the bottom shell 3 being squeezed and deformed at this connection after the screw is tightened.

[0042] The screws connecting and fixing the middle shell and the top shell, and the bottom shell and the laser lens protective cover are all located inside the treatment helmet, which not only avoids excessive exposure of the screws affecting the product's appearance and sales, but also improves the overall structural strength of the treatment helmet compared to the snap-on fixing method.

[0043] The helmet further includes a first pressure plate 71 and a second pressure plate 61. The bottom shell 3 is also integrally formed with a first stud 34 and a second stud 35. A positioning baffle 33 is also provided on the bottom shell 3. A positioning area is formed between the positioning baffle 33, the first stud 34, and the bottom shell 3. The vibration motor 7 is embedded in the positioning area. The positioning area restricts all degrees of freedom of the vibration motor 7 in the non-upward direction. The charging connector 6 is embedded in the rear end of the bottom shell 3. A stepped hole is provided at the rear end of the bottom shell 3 for mating with the charging connector 6. The stepped hole restricts all degrees of freedom of the charging connector 6 in the non-upward direction. The charging connector 6 is embedded in the rear end of the bottom shell 3, with the charging connector 6 socket facing the bottom of the helmet. The first pressure plate 71 and the second pressure plate 61 are respectively connected and fixed to the first stud 34 and the second stud 35 by screws. The first pressure plate 71 and the second pressure plate 61 respectively compress and secure the vibration motor 7 and the charging connector 6, thereby restricting their downward freedom of movement. When the user uses this helmet for treatment, the battery assembly powers the laser hair growth treatment helmet, and the touch screen controls the power on and off and the switching of parameter displays on different working pages. The functionality of the treatment helmet is increased, and the installation structure of the touch display assembly is compact and takes up little space.

[0044] The vibration motor 7 is a linear motor, which has the advantage of good vibration feedback effect. The thickness of the silicone rubber coated on the bottom and vertical surfaces of the linear motor is set to 1-5 mm, and the thickness of the silicone rubber coated is preferably set to 2 mm. The silicone rubber can effectively absorb the resonance of the linear motor and achieve the best vibration feedback effect.

[0045] Solder pads 92 are fixedly provided on both sides of the ends of the split structures 91 of the flexible circuit board 9. The solder pads 92 of adjacent split structures 91 are welded together. The provision of solder pads at the outer ends of the split structures of the flexible circuit board improves assembly efficiency by 30%. The contact points of the solder pads at the outer ends of two adjacent split structures can be adjusted. After the split structures of the flexible circuit board are welded together, the gap is ≤0.1mm. This allows for the installation of more laser heads on the flexible circuit board, increasing the effective treatment area of ​​the laser hair growth treatment helmet by 10%, achieving better treatment results.

[0046] The touch screen assembly 4 is composed of a control mainboard 41 , a touch screen 42 and a screen cover 43 which are fixedly connected. The screen cover 43 is fixedly embedded in the through hole 11 of the middle shell 1 .

[0047] The edge of the through hole 11 of the middle shell 1 is integrally formed with a reinforcing rib 13, and a third stud 17 is integrally formed on the reinforcing rib 13. The reinforcing rib 13 can increase the structural strength at the edge of the through hole 11. The third stud 17 is arranged on the reinforcing rib 13, which can also increase the structural strength of the third stud 17, avoiding the problem of tilting, deformation and cracking at the inner end connection of the third stud 17. A support platform 14 is provided at the lower part of the reinforcing rib 13, and a positioning table 15 is formed between the reinforcing rib 13 and the through hole 11. A positioning groove 16 is provided in the positioning table 15. The lower part of the control main board 41 is placed on the support platform 14, and the support platform 14 can The control motherboard 41 is supported to prevent it from falling under the action of gravity during long-term use and being cut and damaged by screws. The control motherboard 41 is screwed to the third stud 17 by screws, and the edge of the screen cover 43 is set to a U-shaped structure 431. The edge of the screen cover 43 is attached to the positioning table 15, and the U-shaped structure 431 of the screen cover 43 is embedded in the positioning groove 16. The positioning groove 16 restricts all degrees of freedom of the screen cover 43 of the touch display assembly 4 to move non-into the helmet; after the screws fix the control motherboard 41, the freedom of the touch display assembly 4 to move inward can be restricted.

[0048] The laser lens protective cover 5 is provided with heat dissipation holes, and the heat dissipation shell is provided with a long hole structure. The long hole structure can increase the heat dissipation effect and reduce the number of heat dissipation holes.

[0049] A head support pad 8 is fixedly mounted on the inner surface of the bottom shell 3 . The head support pad 8 is configured as an elastic pillow structure. The elastic pillow is fixed to the inner surface of the bottom shell 3 by Velcro for easy replacement.

[0050] like Figure 17 As shown, the head support pad 8 is configured as an airbag assembly, which is composed of an airbag anti-slip pad and a shell fixedly connected. The inner surface of the shell is configured as a contoured structure that matches the bottom shell 3. The shell is screwed and fixedly mounted on the bottom shell 3. The air pump 81 is connected to the airbag anti-slip pad through a hose 85. The pressure sensor is provided on the control main board 41. The pressure sensor is connected to the control main board 41 in a circuit. The pressure sensor connector is connected to the hose 85. The air pump 81 and the pressure sensor are connected to the control main board 41 through a circuit. Two U-shaped positioning plates 82 and two fourth studs 83 are integrally formed on the bottom shell 3. The two U-shaped positioning plates 82 cooperate to form a positioning slot, and the air pump 81 is embedded and installed in the positioning slot. The third pressure plate 84 is screwed and fixed on the fourth stud 83 to press and fix the air pump 81.

[0051] After the user puts on the laser hair growth treatment helmet and starts it, the air pump inflates the airbag's anti-slip pad to a pressure within the range of 180-210 mmHg. The airbag's anti-slip pad presses against the user's head, securing the laser hair growth helmet to the patient's head and preventing it from shaking, ensuring comfort. The pressure sensor transmits a signal to the control board 41, which instructs the air pump 81 to stop. The pressure sensor monitors the air pressure in real time and replenishes gas in response to pressure fluctuations caused by head movement or slow gas leakage. After the laser hair growth treatment is completed after 10-20 minutes, the control board controls the air pump 81 to degas the airbag, allowing the user to remove the laser hair growth treatment helmet. This airbag assembly inflation method has the advantage of adapting to different head circumferences, with a dynamic adaptability range of 50-65 cm (compatible with 99% of adult head shapes), making it suitable for multi-patient scenarios such as hair loss treatment institutions and hospitals.
