Description

Technical Field

[0001] This utility model relates to a scalp care device in the field of microneedle transdermal drug delivery technology, and in particular, a head care cavity and a scalp care massage chair. Background Technology

[0002] Hair loss is a problem that plagues many patients. Hair loss can cause hair to thin, or even result in large bald patches, which seriously affects a person's appearance, thereby impacting their self-confidence and mental health, and may even increase social anxiety.

[0003] Androgenetic alopecia (AGA) is a leading cause of patterned baldness, affecting approximately 50% of men and women by age 50. In men, AGA causes hair loss on the crown and frontal areas of the scalp, while in women it manifests as diffuse thinning of the scalp. AGA is caused by the androgenic effects in individuals with specific genetic predispositions. Specifically, dihydrotestosterone (DHT), a potent androgen derivative of testosterone, is synthesized by the enzyme 5α-reductase and is closely associated with the development of AGA in genetically susceptible individuals.

[0004] One promising approach to treating androgenetic alopecia is photobiological modulation (PBM) using visible light wavelengths, commonly known as low-intensity laser (LLLT) therapy. This can be achieved using lasers or light-emitting diodes (LEDs). LLLT involves the use of visible light, primarily red to infrared wavelengths of approximately 600-1070 nanometers, to exert its biological effects. A growing body of clinical evidence demonstrates the effectiveness of LLLT-based treatments for androgenetic alopecia.

[0005] On December 12, 2024, a study published in the *J. Biophotonics* explored the potential mechanism of action of low-intensity laser therapy for AGA. It investigated the ability of red-orange (620–630 nm) and red (660 nm) light, alone and in combination, to induce biological responses and the ability of these responses to inhibit dihydrotestosterone synthesis.

[0006] Currently, common treatments for hair loss include medication and hair transplant surgery. Hair transplant surgery is expensive and carries certain risks, such as damage to hair follicles; furthermore, the success rate of hair transplants is not 100% due to the limited survival rate of the transplanted follicles. Traditional medication treatments are mostly administered topically or orally. Oral medications cannot directly act on the scalp, and their effects spread throughout the body, potentially placing a significant burden on the liver and kidneys, and possibly affecting male sexual function. While topical medications can act directly on the affected area of ​​the scalp, excessive amounts can be absorbed by other tissues, causing scalp irritation and rapid heartbeat. Long-term overuse can also lead to side effects such as dry skin, itching, and increased dandruff. Additionally, excessive medication residue on the hair and scalp can leave a sticky and uncomfortable feeling. Furthermore, self-treatment requires bending the arm above or behind the head, which is inconvenient and tiring.

[0007] Therefore, there are many areas for improvement in current scalp care solutions and equipment. Utility Model Content

[0008] To address or improve the technical problems encountered by hair loss patients when self-treating, such as significant drug side effects, poor skin experience, and inconvenient operation, this utility model provides a head care cavity and a scalp care massage chair.

[0021] In a preferred embodiment, the nursing element includes a substrate and micro-units formed on the surface of the substrate, wherein the micro-units are at least one of microneedles, microknife, microprotrusions, and nanoneedles.

[0022] The head care cavity in this technical solution can be used alone or integrated into multiple devices. For example, when the head care cavity is installed on a massage chair, the user can enjoy both body and scalp massage simultaneously. Therefore, this technical solution also provides a scalp care massage chair, which includes a chair body and the head care cavity described in any of the above technical solutions, wherein the head care cavity is disposed on the chair body.

[0023] In a preferred embodiment, the chair body is further provided with at least one of a back massage module, a waist massage module, a buttock massage module, an arm massage module, and a leg massage module.

[0024] The above technical solutions will be further explained.

[0025] 1. This technical solution also includes common components such as power supply, circuit board, common electronic components, connectors, and fasteners. The power supply can be a rechargeable power supply or a wired power supply.

[0026] 2. The vibration module can be either an electromagnetically driven vibration mechanism or an electric motor-driven mechanical vibration mechanism. The vibration module can be directly connected to the nursing element and drive the nursing element to vibrate, or it can be indirectly connected to the nursing element through a transmission mechanism and drive the nursing element to vibrate.

[0027] 3. The vibration module drives the care element to vibrate: This vibration can take many forms. It can be a vertical reciprocating motion that drives the care element to move back and forth away from or in contact with the scalp; it can also be a horizontal reciprocating motion that drives the care element to slide back and forth on the scalp, maintaining contact with the scalp; or it can be a combination of the above vertical and horizontal reciprocating motions.

[0028] 4. The slide rail is curved to vertically envelop the user's head: The slide rail in this technical solution is arranged vertically, with an upper and lower end. The upper end is close to the user's forehead, and the lower end is close to the back of the user's head. The slide rail has a curvature that matches the size of the patient's head. When the user lies on this scalp care massage chair, the slide rail is positioned at the top of the patient's head, with its upper end close to the user's forehead and its lower end close to the back of the user's head. The curved slide rail vertically partially envelops the patient's head.

[0029] 5. The frame is curved to horizontally envelop the user's head: The frame in this technical solution is arranged horizontally, with both ends close to the sides of the user's head, such as the ears. The frame has a curvature that matches the size of the patient's head. When the user lies on this scalp care massage chair, the frame in this technical solution can horizontally (laterally) partially envelop the patient's head.

[0030] 6. The material used to fabricate the micro-unit can be at least one of single-crystal silicon, ceramics, metals, and polymers. In this technical solution, the nursing element is a disposable consumable in the field of microneedle transdermal drug delivery technology, specifically one of microneedle chips, nanocrystals, microneedle wafers, and microknife wafers. The length of the micro-unit is no greater than 3000 micrometers, and the diameter of the end of the micro-unit is no greater than 200 nanometers.

[0031] 7. Image capture unit: The image capture unit can be a video acquisition device such as a camera, an image acquisition device such as a high-speed camera, or other suitable image capture and acquisition device.

[0032] The inventive concept and beneficial effects of this utility model are as follows: This head care cavity is equipped with care elements, and the micro-units on the care elements are at the micrometer or even nanometer scale. This technical solution uses care elements to unclog and care for the scalp, which can weaken the stratum corneum barrier of the scalp and improve the transdermal absorption efficiency. This technical solution belongs to microneedle transdermal drug delivery technology, which is an innovation and upgrade of traditional topical drug delivery methods. This head care cavity can improve the absorption of active ingredients such as drugs by the scalp. When the scalp absorption efficiency is improved, the total amount of drug applied by the patient can be reduced, the amount of drug remaining on the skin surface is reduced, the stickiness and unpleasant feeling of the skin is reduced, the time and dosage of drug absorption by other tissues are reduced, and the side effects are also reduced.

[0033] This technical solution can also integrate the head care cavity into a massage chair, combining scalp care with body massage functions. This changes the traditional care posture, allowing patients to maintain a comfortable body position during treatment. Simultaneously, through the cooperation of slide rails and frames, this technical solution enables the care components to provide systematic and comprehensive head care in both horizontal and vertical directions. Through the coordinated action of components such as motion controllers, vibration modules, and spray controllers, intelligent and automatic care of the patient's scalp area can be achieved. Patients no longer need to raise their arms high or extend them backward for extended periods, effectively improving the comfort and convenience of scalp care. Attached Figure Description

[0042] In order to solve or improve the technical problems of large drug side effects, poor skin experience and inconvenience of operation when hair loss patients treat themselves, this utility model provides a scalp care massage chair. Figure 1 This is a partial cross-sectional structural diagram of one embodiment of the head care cavity and scalp care massage chair of this utility model. Figure 2 yes Figure 1 A magnified structural diagram of point A in the middle. Figure 3 This is a top view schematic diagram of the scalp care unit in one embodiment of the head care cavity and scalp care massage chair of this utility model. Figures 1 to 3 As shown, the scalp care massage chair includes a chair body 1 and a head care cavity 2. The head care cavity 2 is disposed on the chair body 1 and includes a shell 21, a slide rail 22, a motion controller 23, and a scalp care unit 3. The scalp care unit 3 is slidably disposed on the slide rail 22, and the motion controller 23 can control the scalp care unit 3 to move or stop on the slide rail 22. The scalp care unit 3 includes a vibration module 31 and a care element 30 that can be driven to vibrate by the vibration module 31.

[0043] As is readily understood, this technical solution also includes common components such as a power supply, circuit board, common electronic components, connectors, and fasteners. The power supply can be a rechargeable power source, such as a lithium battery, allowing the scalp care massage chair to be flexibly moved and arranged, suitable for flexible repositioning in commercial settings. Alternatively, the power supply can be a wired power source, connected to a fixed socket.

[0044] like Figure 1 As shown, the chair body 1 has a seating compartment where the user can comfortably recline. In some embodiments, the chair body 1 of this scalp care massage chair has an angle adjustment function, allowing the user to sit up and lie down flexibly adjust their body posture. It should be noted that in some embodiments, the chair body 1 is also equipped with a back massage module, a waist massage module, a buttock massage module, an arm massage module, or a leg massage module to provide the user with a comprehensive massage and care experience. Figure 1 As shown, a display 11 is mounted on the chair body 1, and the display 11 is electrically connected to a central processing unit (not shown). The display 11 is fixed to the front of the seat for easy viewing by the user. Through the display 11, the user can conveniently and intuitively understand information such as the condition of their head and the progress of care.

[0045] A head care cavity 2 is provided on the chair body 1. The head care cavity 2 is helmet-shaped and can partially surround and cover the user's head. Figure 1 As shown, the outer shell 21 of the head care cavity 2 is integrally formed with the shell of the chair body 1, and the head care cavity 2 and the chair body 1 are not detachable. It is easy to understand that the head care cavity 2 can also be detachably assembled with the chair body 1.

[0046] like Figures 1 to 3 As shown, a slide rail 22 is provided inside the head care cavity 2. The slide rail 22 is arranged vertically and has an upper end and a lower end. The upper end is close to the user's forehead, and the lower end is close to the back of the user's head. The slide rail 22 has a curvature that matches the size of the patient's head, and the slide rail 22 is curved to vertically cover the user's head. Figure 3 As shown, in this embodiment, the head care cavity 2 is symmetrically provided with two slide rails 22. The radial cross-section of the slide rails 22 is circular. Alternatively, the slide rails 22 can also be rectangular or other suitable shapes.

[0047] like Figure 2 and Figure 3As shown, a scalp care unit 3 is slidably mounted on a slide rail 22. In this embodiment, a drive module 33 is mounted on the scalp care unit 3. The drive module 33 includes a drive motor, a transmission mechanism, and a drive roller 331, wherein the drive roller 331 is in contact with the surface of the slide rail 22. When the drive motor is started, the drive roller 331 rolls along the surface of the slide rail 22, thereby causing the scalp care unit 3 to slide relative to the slide rail 22. Figure 1 As shown, in this embodiment, the motion controller 23 is arranged on the chair body 1 at a position that is convenient for the user's fingers to touch. The motion controller 23 is electrically connected to the drive module 33. The motion controller 23 can control the rotation direction and rotation speed of the drive roller 331, thereby controlling the scalp care unit 3 to move along the slide rail 22 or stop at a certain position.

[0048] like Figure 2 and Figure 3 As shown, the frame 32 of the scalp care unit 3 is mounted on the drive module 33. The frame 32 is curved to form an arc that can laterally cover the user's head. In this embodiment, the frame 32 is arranged horizontally, with its two ends close to the sides of the user's head, such as the ears. The frame 32 has a curvature that matches the size of the patient's head. In this embodiment, the frame 32 is elastic, allowing it to deform elastically and expand outwards when the user's head circumference is large.

[0049] like Figure 2 or Figure 3 As shown, the vibration module 31 of the scalp care unit 3 is arranged on the frame 32. In this embodiment, the scalp care unit 3 has multiple vibration modules 31, which are equidistantly arranged on the side of the frame 32 facing the user's head. Figure 3 As shown, in this embodiment, a care element 30 is mounted on each vibration module 31, and each vibration module 31 drives one care element 30 to vibrate. It is readily apparent that in some embodiments, multiple care elements 30 can be mounted on each vibration module 31, or all care elements 30 on the scalp care unit 3 can be driven by a single vibration module 31. It is sufficient to arrange the care elements 30 in an array along the frame 32.

[0050] It should be noted that the vibration module 31 can be an electromagnetically driven vibration mechanism or an electric motor mechanically driven vibration mechanism. The vibration module 31 can be directly connected to the care element 30 and drive the care element 30 to vibrate, or it can be indirectly connected to the care element 30 through a transmission rod and drive the care element 30 to vibrate. It should also be noted that the vibration mode of the vibration element 30 can take various forms: it can be a reciprocating motion away from or in contact with the scalp, performing a vertical reciprocating motion perpendicular to the scalp; it can also be a reciprocating motion sliding on the scalp, maintaining contact with the scalp, performing a lateral reciprocating motion; or it can be a combination of the above vertical and lateral reciprocating motions.

[0051] Figure 4 This is an enlarged structural schematic diagram of the care element in one embodiment of the head care cavity and scalp care massage chair of this utility model. Figure 4 As shown, in this embodiment, the care element 30 includes a substrate 301 and micro-units 302 formed on the surface of the substrate 301. The micro-units 302 are at least one of microneedles, microknives, microprotrusions, and nanoneedles. The material used to fabricate the micro-units 302 can be at least one of single-crystal silicon, ceramics, metals, and polymer materials. In this technical solution, the care element 302 is a disposable consumable in the field of microneedle transdermal drug delivery technology, specifically one of microneedle chips, nanocrystals, microneedle wafers, and microknive wafers. The length of the micro-unit 302 is no greater than 3000 micrometers, and the diameter of the end of the micro-unit 302 is no greater than 200 nanometers.

[0052] like Figure 2 and Figure 3 As shown, the scalp care unit 3 also includes a medication application module 4. The medication application module 4 includes a medication reservoir, a spray controller, and a spray nozzle. The medication reservoir can be fixed to the drive module 33 or the frame 32, or it can be mounted on the outer casing 21 or the chair body 1. The spray controller can be located on the chair body 1 in a position easily accessible to the user's fingers, or it can be integrated with the motion controller 23. Figure 2 As shown, the nozzle 40 of the medication application module 4 is arranged on the vibration module 31, and the nozzle 40 is connected to the frame 32 through the housing of the vibration module 31. It is easily understood that the nozzle 40 can also be directly mounted on the frame 32. In this embodiment, the medication application module 4 has multiple nozzles 40, the number of which is the same as the number of care elements 30. Each nozzle 40 is paired with a care element 30, and the nozzle 40 is positioned below the care element 30. The spray direction of the nozzle 40 is tilted upwards, towards the position where the care element 30 contacts the scalp.

[0053] like Figure 2 and Figure 3As shown, the scalp care unit 3 is also provided with a distribution unit 5. The distribution unit 5 has a comb-like structure and functions to separate the hair strands, making it easier for the care element 30 to deeply contact the skin. In this embodiment, there are multiple distribution units 5, and the number of distribution units 5 is the same as the number of care elements 30. The distribution units 5 and care elements 30 are paired one-to-one, and the distribution units 5 are located above the care elements 30.

[0054] like Figure 2 and Figure 3 As shown, the scalp care unit 3 is also equipped with a light-emitting unit 6. In this embodiment, there are multiple light-emitting units 6, each paired with a care element 30. The light-emitting units 6 are disposed on the vibration module 31. When the care element 30 moves up and down under the drive of the frame 32, the light-emitting units 6 can move synchronously with the care element 30. While the care element 30 is caring for the scalp, the light-emitting units 6 can synchronously emit red light to care for the scalp area treated by the care element 30. It is easy to understand that the light-emitting units 6 can also be disposed on the frame 32, which can also achieve synchronous movement with the care element 30. Alternatively, the light-emitting units 6 can also be arranged on the side surface of the head care cavity 2 facing the user's scalp to achieve comprehensive, continuous, and long-term light irradiation care for the scalp. In this embodiment, the light-emitting element 6 is an LED lamp with a power of not less than 4 milliwatts and not more than 30 milliwatts. Optionally, the power of the LED lamp is 5 milliwatts or 10 milliwatts. The light emitted by the LED lamp can inhibit the synthesis of dihydrotestosterone and promote hair regeneration. Its wavelength is not less than 600nm and not greater than 1500nm. Optionally, the wavelength is 620-740nm, preferably 620nm, 625nm, 630nm, 655nm, 660nm, or 680nm.

[0055] like Figure 2 and Figure 3As shown, an image capture unit 7 is also provided on the head care cavity 2, and the image capture unit 7 is electrically connected to the central processing unit. In this embodiment, the image capture unit 7 is fixed on the frame 32 of the scalp care unit 3. During the care process, the image capture unit 7 can capture images of the user's head in real time and transmit the image information to the central processing unit. After analyzing and organizing the image information, the central processing unit transmits key information such as hair density and scalp condition to the display 11. In some embodiments, the central processing unit is also electrically connected to the motion controller 23, the spray controller, and the light-emitting unit 6. The central processing unit can display information such as the care progress, care direction, care intensity, drug application, and light intensity of the scalp care unit 3 on the display 11 to help the user understand their own situation and thus facilitate the user to adjust the motion controller 23 and the spray controller according to their own situation, thereby performing targeted scalp treatment on key areas. It is conceivable that in some embodiments, the image capture unit 7 can also be fixed on the side surface of the head care cavity 2 facing the user's scalp.

[0056] This technical solution integrates scalp care functions into a massage chair, changing the traditional care posture and allowing patients to maintain a comfortable body position while receiving treatment. When the user lies on this scalp care massage chair, the slide rail 22 is positioned at the top of the patient's head, with its upper end close to the user's forehead and its lower end close to the back of the user's head. The slide rail 22 curves vertically, partially enveloping the patient's head; simultaneously, the frame 32 can also partially envelop the patient's head horizontally. Through the coordinated operation of the motion controller 23, vibration module 31, spray controller, slide rail 22, and frame 32, the distribution unit 5 separates the hair strands, exposing the patient's scalp; the care element 30 makes full contact with the scalp and provides unblocking care; the nozzle 40 sprays the medication onto the scalp, completing immediate medication application. In summary, this technical solution can provide systematic and comprehensive intelligent automatic care for the patient's scalp area. Users can adjust the scalp care unit 3 to provide comprehensive or targeted care for their scalp while maintaining a comfortable posture. At the same time, the spray controller can be used to precisely apply medication, allowing users to enjoy an intelligent and convenient scalp care experience.

[0057] It should be noted that the head care cavity in this technical solution can also be used independently in other application scenarios. For example, in some embodiments, the head care cavity has a wearing fixation device that can be installed on the user's shoulder, head, or back, providing good support and fixation for the head care cavity, allowing it to be worn stably and securely on the user's head. The head care cavity can then be activated to care for the scalp. In these embodiments, the user can move freely without affecting other normal activities.

[0058] It is easy to understand that in other usage scenarios, the head care cavity can also be integrated into a helmet to form a headband-style scalp care product; in some special usage scenarios, the head care cavity can also be integrated into a car, providing users with a moment of relaxation and comfort care when they are resting in the car.
