Description

Technical Field

[0001] This invention belongs to the field of drug delivery technology, and particularly relates to a roller massage scalp drug delivery device. Background Technology

[0002] Scalp drug delivery is a method of administration where medication is delivered directly to the scalp to exert its therapeutic effect locally. It is a localized drug delivery method, bypassing oral and systemic intravenous administration; the medication primarily works at the scalp level. Existing roller-type scalp drug delivery devices have a relatively simple structure, directly mounted on a storage container. The medication enters the comb teeth by gravity, contacts the roller, and adheres to it. The roller rotates during application, continuously picking up and transferring the medication to the scalp. During this process, the stored medication remains in contact with the roller that has touched the scalp. Even at low flow rates, without an isolation structure, prolonged and repeated use can easily lead to overall contamination of the medication. The patent document with authorization publication number CN223303260U exhibits this problem. Summary of the Invention

[0003] This invention provides a rollerball massage scalp medication applicator, aiming to solve the problem mentioned in the background art that the existing rollerball scalp medication applicator has a simple structure, the medicine flows into the comb teeth by gravity and then adheres to the rollerball, and the rollerball continuously picks up the stored medicine and transfers it to the scalp when it rolls to apply the medicine. However, the stored medicine always keeps in contact with the rollerball that has been in contact with the scalp, which easily causes overall medicine contamination.

[0004] To address the aforementioned problems, the present invention provides a rollerball massage scalp medication applicator, comprising: a medication box for storing medication; a connecting shell detachably mounted on the medication box; a plurality of comb bars fixed to the connecting shell for combing hair; a connecting cylinder threaded onto the comb bars, the connecting cylinder having an opening; massage beads embedded in the opening for direct scalp medication administration, the massage beads extending outside the opening and contacting the scalp; and a metering structure disposed within the connecting shell for assisting in quantitative medication administration and isolating the medication.

[0017] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0018] This invention provides a rollerball massage scalp medication applicator, such as... Figure 1-10 As shown, the roller massage scalp medication applicator includes: a medication box 1 for storing medication; a connecting shell 5 detachably mounted on the medication box 1; a plurality of comb bars 6 fixed on the connecting shell 5 for combing hair; a connecting cylinder 7 threaded onto the comb bars 6, the connecting cylinder 7 having an opening; massage beads 8 embedded in the opening for direct scalp medication administration, the massage beads 8 extending outside the opening and contacting the scalp; and a metering structure disposed within the connecting shell 5 for assisting in quantitative medication administration and isolating the medication.

[0019] In this embodiment, during use, the user installs the connecting shell 5 on the medicine box 1, so that the two form a sealed liquid storage space. The medicine contained in the medicine box 1 is distributed and controlled by the quantitative structure in the connecting shell 5, and then the medicine enters each comb bar 6. During use, the spherical part of the massage bead 8 extends out from the opening of the connecting tube 7 and directly adheres to the scalp surface. The user pushes the medicine dispenser along the scalp direction, and the massage bead 8 rolls on the scalp and rotates around its own axis at the same time, which massages and stimulates the scalp while evenly coating the medicine attached to its surface to all parts of the scalp. By using a threaded connection in the connecting cylinder 7, the massage beads 8 become independently detachable and replaceable components. After multiple uses, users can remove the massage beads 8 that have been in contact with the scalp from the connecting cylinder 7 and replace them with new ones, thus preventing cross-infection and ensuring the cleanliness and safety of the remaining medication. The quantitative structure allows for control of the amount of medication dispensed each time, avoiding waste due to excessive dispensing or insufficient dosage affecting efficacy. This achieves the function of auxiliary quantitative drug administration, improving the controllability of medication use. While rolling and applying the medication, the massage beads 8 provide a physical massage to the scalp, promoting local blood circulation and facilitating transdermal absorption of the medication, thereby improving the therapeutic effect of the medication on the scalp. The comb bar 6 combs the hair while applying the medication, preventing hair from tangling around the applicator or obstructing contact between the medication and the scalp, making the medication administration process smoother and improving the user experience.

[0020] In a further preferred embodiment of the present invention, a threaded cylinder 2 is fixed on the medicine box 1, and an installation cylinder 3 is threaded onto the external thread of the threaded cylinder 2. An isolation plate 4 is fixed on the installation cylinder 3, and the isolation plate 4 is fixed inside the connecting shell 5. The threaded cylinder 2 is provided with a medicine discharge channel communicating with the medicine box 1. The isolation plate 4 is provided with a medicine discharge port, and the bottom of the isolation plate 4 is provided with a buffer chamber 9 for buffering medicine. The medicine discharge channel, the liquid discharge port, and the buffer chamber 9 are connected.

[0021] In this embodiment, when in use, the user screws the medicine box 1 and the connecting shell 5 together with the threaded cylinder 2 and the mounting cylinder 3. When the medicine dispenser is used, the medicine reaches the medicine outlet on the isolation plate 4 along the medicine discharge channel, and then enters the buffer chamber 9 at the bottom of the isolation plate 4 for temporary storage. After a certain amount of medicine accumulates in the buffer chamber 9, the pressure is stopped, and the medicine enters the comb bar 6 under the action of gravity and capillary action, so that the massage beads 8 can continuously pick up and transfer the medicine to the scalp during the rolling process. By setting a buffer chamber 9 at the bottom of the isolation plate 4, a buffer storage link is added to the path of the medicine from the medicine box 1 to the comb bar 6. The medicine no longer flows directly from the medicine box 1 into the gap of the comb bar 6 in large quantities, but first accumulates and buffers in the buffer chamber 9, and then seeps out at a stable and controllable rate. This effectively avoids the problem of fluctuating medicine flow caused by changes in the liquid level in the medicine box 1 or changes in the user's operating angle. It ensures that the dosage of medicine picked up by the massage bead 8 is basically consistent each time, which greatly improves the uniformity and repeatability of drug administration. The isolation plate 4 physically isolates the medicine discharge channel from the internal space of the connecting shell 5, so that the flow path of the medicine is limited to the closed loop formed by the medicine discharge channel, the medicine discharge port and the buffer chamber 9. The remaining unused medicine is always isolated in the medicine box 1 and will not mix with the medicine that has been picked up by the massage bead 8 in the connecting shell 5. This fundamentally eliminates the risk of medicine that has been in contact with the scalp area flowing back and contaminating the stored medicine, ensuring the hygiene and safety of the entire bottle of medicine during its use period.

[0022] In a further preferred embodiment of the present invention, the metering structure includes a spring 10 fixed inside the connecting shell 5, a plug plate 11 fixed to the top of the spring 10 for sealing the drain port, a sealing gasket 12 fixed to the top of the plug plate 11 and in contact with the bottom of the isolation plate 4, and a plug block 15 fixed to the bottom of the plug plate 11 and extending into the comb rod 6 for sealing the comb rod 6. The plug block 15 is covered with a sealing sleeve 16 that contacts the inner wall of the comb rod 6.

[0023] In this embodiment, when in use, after the user rotates the mounting cylinder 3 to connect and lock the connecting shell 5 with the medicine box 1, the user squeezes the medicine box 1. The medicine in the medicine box 1 reaches the discharge port on the isolation plate 4 through the discharge channel. At this time, the medicine continuously presses against the sealing gasket 12, pushing the sealing gasket 12 together with the blocking plate 11 and the spring 10 to move downward as a whole. The spring 10 is compressed and stores energy under pressure. The blocking block 15 moves down with the blocking plate 11 and enters the inner cavity of the comb rod 6. When the user stops operating or the medicine pressure decreases, the spring 10 releases the stored energy and pushes the blocking plate 11 to spring back and reset. The blocking block 15 rises again under the action of the spring 10 and leaves the inner cavity of the comb rod 6, and the medicine enters the comb rod 6. Through the elastic restoring force of the spring 10 and the mechanical linkage between the blocking plate 11 and the blocking block 15, the automatic control of the flow and blockage of the medicine is realized. The user does not need to judge the amount of medicine by feeling. Each press or docking operation can automatically release the preset amount of medicine into the gap of the comb bar 6, ensuring that the total amount of medicine that the massage bead 8 can pick up is basically constant each time medicine is applied, thus improving the consistency of treatment.

[0024] In a further preferred embodiment of the present invention, the springs 10 are arranged in groups, and each of the multiple springs 10 is covered with a rubber protective sleeve 13 for isolating the agent. The top and bottom of the rubber protective sleeve 13 are respectively connected to the bottom inner wall of the blocking plate 11 and the connecting shell 5. Each of the multiple springs 10 is provided with a limiting telescopic rod 14 for limiting the extension and retraction path of the spring 10. The limiting telescopic rod 14 is fixed on the bottom inner wall of the connecting shell 5 and connected to the blocking plate 11.

[0025] In this embodiment, when the connecting shell 5 and the medicine box 1 are docked and locked, the medicine is pressed downward through the medicine outlet on the isolation plate 4. Under the pressure of the medicine, multiple springs 10 are compressed downward synchronously along the limited path of the limiting telescopic rod 14. The rubber protective sleeve 13 undergoes elastic deformation along with the blocking plate 11. Throughout the entire process of the extension and retraction of the spring 10, the spring 10 is always wrapped inside it, preventing the medicine from contacting the metal surface of the spring 10. By grouping the springs 10, the driving force for quantitative drug administration is evenly distributed from multiple points, making the force on the springs 10 more balanced. By setting the rubber protective sleeve 13, the drug is completely isolated from the metal surface of the springs 10, avoiding chemical reactions between the active ingredients in the drug and the metal, which could lead to reduced efficacy or the production of harmful substances. It also prevents the springs 10 from rusting and aging due to long-term contact with the drug, thus extending the service life of the quantitative structure. By setting the limiting telescopic rod 14, the risk of the springs 10 bending or losing control due to lateral forces during repeated compression and rebound can be prevented.

[0026] In a further preferred embodiment of the present invention, a limiting frame 17 is fixed to the bottom of the connecting shell 5, and a protective cover 19 is provided on the limiting frame 17. The protective cover 19 is sleeved on the plurality of comb rods 6. A protruding ring 18 is fixed on the limiting frame 17, and a limiting opening for accommodating the protruding ring 18 is provided on the inner wall of the protective cover 19. The protruding ring 18 cooperates with the limiting opening to stabilize the protective cover 19.

[0027] In this embodiment, when the drug delivery device is in a non-working or stored state, the user puts the protective cover 19 on the bottom of the connecting shell 5, so that the inner wall of the protective cover 19 first passes over the lower ends of the multiple comb rods 6, and then the protective cover 19 continues to move down until the limiting hole on its inner wall aligns with and engages with the protruding ring 18 fixed on the limiting frame 17. The protruding ring 18 is fully embedded in the limiting hole. At this time, the protective cover 19 is locked at the bottom of the connecting shell 5 by the cooperation of the limiting frame 17 and the protruding ring 18, and cannot continue to fall down or slide up. The engagement of the upper ring 18 on the limiting bracket 17 and the upper limit opening of the protective cover 19 provides a clear positioning and limiting mechanism for the protective cover 19, ensuring that the protective cover 19 can be firmly held at the bottom of the connecting shell 5 after being put on, and will not fall off accidentally due to carrying, shaking or daily contact, ensuring that the massage beads 8 and the comb bar 6 are always in a closed and protected state when not in use.

[0028] In a further preferred embodiment of the present invention, an isolation net 29 is fixed inside the comb bar 6, and a sponge block 30 for absorbing medicine is provided between the isolation net 29 and the connecting cylinder 7. The sponge block 30 is in contact with the massage bead 8 to assist in the uniform application of medicine, and the isolation net 29 is used to limit the position of the sponge block 30.

[0029] In this embodiment, after the medicine flows into the inner cavity of the comb bar 6 through the medicine outlet and medicine outlet channel, the medicine first contacts the sponge block 30 located between the connecting cylinder 7 and the isolation net 29. The sponge block 30 quickly absorbs and temporarily stores the medicine that flows through it by utilizing its own porous adsorption properties. Subsequently, the medicine is evenly diffused in the sponge block 30 towards the surface in contact with the massage bead 8 through capillary action. During the process of the massage bead 8 rolling on the scalp to apply the medicine, its spherical surface continues to be in close contact with the surface of the sponge block 30. Every time the massage bead 8 rotates once, it scrapes a thin and uniform medicine film from the wet surface of the sponge block 30 and transfers it to the scalp surface. By setting up the isolation net 29, a reliable axial positioning reference is provided for the sponge block 30, so that the sponge block 30 will not deviate from its working position due to vibration or compression during long-term use. This avoids the risk of the sponge block 30 shifting and causing changes in the drug flow path or blockage of the comb bar 6 cavity, ensuring the long-term stability and reliability of the drug delivery structure. The sponge block 30 acts as an intermediate buffer and distribution medium between the drug flow from the comb bar 6 cavity to the massage beads 8, dispersing and storing the originally concentrated drug and continuously supplying it to the massage beads 8 in a uniform and moist state. This effectively eliminates the problem of uneven drug distribution on the surface of the massage beads 8 due to excessive instantaneous flow rate caused by gravity, making the dosage of drug applied to the scalp more consistent with each roll, improving the uniformity of local drug delivery to the scalp and the predictability of the treatment effect.

[0030] In a further preferred embodiment of the present invention, the bottom of the connecting cylinder 7 is provided with an arc-shaped chamfer to prevent scratching the scalp, and a limiting protrusion is provided inside the connecting cylinder 7. The limiting protrusion contacts the massage bead 8 to stabilize the massage bead 8.

[0031] In this embodiment, after the massage bead 8 is installed in the connecting cylinder 7, the limiting protrusion inside the connecting cylinder 7 forms a surface contact with the outer spherical surface of the massage bead 8. The limiting protrusion constrains the axial and radial movement of the massage bead 8, so that the massage bead 8 maintains a stable installation posture in the connecting cylinder 7 and will not shake or fall off due to vibration or pressure during the application of medicine. By setting an arc-shaped chamfer at the bottom of the connecting cylinder 7, the risk of scratches caused by hard edge contact between the connecting cylinder 7 and the scalp can be eliminated from the structural level. Especially when there are small wounds or sensitive areas on the scalp, the arc-shaped chamfer can soften the contact boundary, making the movement of the applicator on the scalp smoother and gentler, improving the user's comfort and safety, and reducing the possibility of secondary scalp damage caused by improper operation. The limiting protrusion inside the connecting cylinder 7 and the massage bead 8 cooperate to provide reliable installation and positioning for the massage bead 8, so that the massage bead 8 can still maintain the correct position inside the connecting cylinder 7 after long-term repeated rolling and wear, without any abnormal state such as loosening, swaying or jamming, ensuring that the contact angle and contact area between the massage bead 8 and the scalp are always consistent each time medication is applied.

[0032] In a further preferred embodiment of the present invention, a groove is provided on the outer wall of the protective cover 19, and an anti-slip cylinder 20 for increasing grip friction is fixed in the groove. The anti-slip cylinder 20 is attached to the groove by hot melt adhesive.

[0033] In this embodiment, when the user needs to remove the protective cover 19 or grasp the protective cover 19 for operation while storing, the user's fingers naturally rest on the outer wall of the protective cover 19, with the fingertips and palms aligned with the anti-slip cylinder 20. The groove provides an installation and positioning space for the anti-slip cylinder 20, making the outer wall surface of the anti-slip cylinder 20 basically flush with the outer wall surface of the protective cover 19. This allows the protective cover 19 to be placed stably when laid flat, without becoming unstable due to the protrusion of the anti-slip cylinder 20.

[0034] In a further preferred embodiment of the present invention, a replenishment pipe 27 is provided on the side of the medicine box 1 away from the threaded cylinder 2. The replenishment pipe 27 is used to provide a medicine replenishment inlet. The replenishment pipe 27 is also used to help restore the air pressure in the medicine box 1 after squeezing out the medicine. A plug cap 28 for sealing the replenishment pipe 27 is threaded on the replenishment pipe 27.

[0035] In this embodiment, when the medicine in the medicine box 1 is gradually consumed, causing the liquid level to drop, the internal space of the medicine box 1 increases, and the internal air pressure decreases accordingly, forming a negative pressure state. At this time, the user unscrews the cap 28 on the replenishment tube 27 and injects the external replenishment medicine into the medicine box 1 through the replenishment tube 27. After the replenishment medicine flows into the medicine box 1 through the replenishment tube 27, the air pressure inside the medicine box 1 gradually rises to balance with the external atmospheric pressure, and the medicine refills the internal space of the medicine box 1. Then the user screws the cap 28 back onto the replenishment tube 27 to complete the seal. During normal application of medicine, when the medicine flows out through the discharge channel, the inside of the medicine box 1 will also have a negative pressure tendency due to the reduction of medicine. This can be resolved by opening the cap 28. By placing the replenishment tube 27 on the side of the medicine box 1 away from the threaded cylinder 2, the replenishment operation and the installation direction of the connecting shell 5 do not interfere with each other. The replenishment tube 27 has the dual functions of replenishment and air pressure balance, avoiding the problem of drug outflow obstruction or flow rate reduction due to excessive internal negative pressure, and ensuring the consistency and stability of drug flow rate throughout the entire cycle from first use to drug depletion.

[0036] In a further preferred embodiment of the present invention, each of the plurality of comb bars 6 is provided with a drug channel communicating with the buffer compartment 9, and the inner diameter of the drug channel is not higher than 5 mm, in order to prevent excessive drug output.

[0037] In this embodiment, when the buffer compartment 9 at the bottom of the isolation plate 4 accumulates a sufficient amount of medicine, the medicine flows under the action of gravity and then enters the preset medicine channel inside each comb bar 6. Since the inner diameter and length of the medicine channel are limited to a small range, the medicine is subject to the dual constraints of frictional resistance and fluid viscosity resistance of the channel wall when passing through the narrow channel, and the flow rate is slowed down. When the massage bead 8 rolls on the scalp to apply medicine, its spherical surface picks up the medicine from the gap, and the medicine channel continuously replenishes the medicine to the gap at a stable and minute rate, forming a continuous and restrained supply process. By limiting the inner diameter of the drug channel to an extremely small size, a physical throttling barrier is set up for the drug output from a fluid dynamics perspective. This eliminates the problem of excessive drug flowing into the gap of the comb bar 6 due to excessive gravitational potential energy when the liquid level in the drug box 1 is high. This ensures that the dosage of drug picked up by the massage beads 8 each time is always within a controllable range, improving the dosage accuracy and treatment safety of scalp drug delivery.

[0038] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments: In another embodiment of the present invention, the medicine box 1 is provided with mounting openings on both sides, and pinch plates 21 extending into the mounting openings are installed on both sides of the medicine box 1. An elastic connecting piece 22 connected to the inner wall of the mounting opening and used to prevent leakage is fixed on the pinch plate 21. The medicine box 1 is provided with a protective structure on both sides to close the mounting openings to protect the pinch plate 21 and prevent accidental contact.

[0039] In this embodiment, when the user needs to expel the medicine by squeezing the medicine box 1, the user must first remove the protective structure on the mounting openings on both sides of the medicine box 1, exposing the pinch plate 21 from its closed state. Then, the user's thumb and fingers are aligned with the pinch plates 21 on both sides of the medicine box 1 and squeeze inwards simultaneously. After being subjected to force, the pinch plate 21 deflects and compresses towards the inside of the mounting opening, and the internal space of the medicine box 1 decreases accordingly. Under the action of squeezing pressure, the medicine is discharged outwards through the medicine discharge channel. During the process of squeezing the pinch plate 21 inwards, the elastic connecting piece 22 fixed on the pinch plate 21 simultaneously bends and deforms. When the user releases the pinch plate 21, the elastic connecting piece 22 releases its stored energy and drives the pinch plate 21 to spring back to its original position. The internal space of the medicine box 1 is restored, and external air enters the medicine box 1 through the liquid replenishment pipe 27 to compensate for the air pressure. The pinch plate 21 completely returns to its initial position and is resealed and protected by the protective structure. By integrating an elastic connecting piece 22 onto the pinch plate 21, dynamic sealing is implemented at the edge of the installation opening throughout the entire process of the medicine box 1 being squeezed and discharged. This fundamentally solves the problem of leakage caused by the gap between the pinch plate and the box body in traditional squeeze-type medicine boxes 1. It ensures that the medicine can only flow out through the discharge channel in a directional manner, avoiding waste and pollution caused by the medicine overflowing from the gap of the installation opening. The protective structure completely encloses the pinch plate 21 when not in use, effectively preventing accidental contact with the pinch plate 21 caused by friction from clothing, collision, or squeezing during carrying or storage. This avoids waste caused by the medicine being squeezed out at unexpected times or abnormal internal pressure of the medicine box 1, and also protects the pinch plate 21 from external damage, extending its service life.

[0040] In another embodiment of the present invention, the protective structure includes a baffle 23 hinged to the medicine box 1, a suction cup 24 fixed to the baffle 23, and a recess 25 provided on the medicine box 1 for accommodating the suction cup 24. A pull plate 26 for providing an operating grip point is fixed on the baffle 23.

[0041] In this embodiment, when the user needs to start the dispensing operation, they pinch the pull plate 26 on the baffle 23 and apply force outward. The baffle 23 rotates outward around the hinge point between it and the medicine box 1. Then the user lifts the suction cup 24 off the baffle 23, so that the suction cup 24 is released from the suction fixation state of the notch 25. At this time, the protective structure is fully opened, the pinch plate 21 is exposed, and the user can perform the double-sided squeezing dispensing operation normally. After the dispensing is completed, the user reverses the operation, aligns the suction cup 24 with the notch 25 on the medicine box 1 and presses it in. A negative pressure suction fit is formed between the suction cup 24 and the notch 25, locking the baffle 23 in a closed state. Then the pull plate 26 is released, and the baffle 23 remains closed under the suction force and gravity of the suction cup 24, completely covering and protecting the pinch plate 21. The baffle 23 is automatically locked by the negative pressure adsorption of the suction cup 24 and the notch 25. Compared with the traditional buckle or magnetic adsorption method, the suction cup 24 does not need to be precisely aligned with a specific position. The user only needs to press the suction cup 24 roughly near the notch 25 and it will automatically stick and fix itself by negative pressure. The operation is simple and quick. By setting the baffle 23, it can completely cover the pinch plate 21 and block the installation opening in the closed state, forming a physical isolation barrier, which effectively prevents accidental contact by external force, dust intrusion, or leakage of medicine due to accidental squeezing when not in use.

[0042] In another embodiment of the present invention, the protective cover 19 is provided with a disinfection component 31 for assisting in the disinfection of the surface of the comb bar 6, the protective cover 19 is provided with a battery box 32, and the outer wall of the battery box 32 is provided with a control panel 37.

[0043] In this embodiment, when the device is not in use and the protective cover 19 is fitted over the comb bar 6 and locked by the limiting frame 17, the user operates it through the control panel 37 of the battery box 32 on the outer wall of the protective cover 19. After receiving the user's start command, the control panel 37 supplies power to the disinfection component 31, and the disinfection component 31 disinfects the outer wall surface of the comb bar 6 under the power of the power. By integrating the disinfection component 31 inside the protective cover 19, the disinfection operation and the storage function of the protective cover 19 are combined into one. Users do not need to carry additional disinfection tools or manually disinfect the comb bar 6 and massage beads 8 before use. The surface of the comb bar 6 can be automatically disinfected each time the medication is stored, which simplifies the operation process and improves the hygiene and safety of use.

[0044] In another embodiment of the present invention, the disinfection component 31 includes a housing 33 fixed on the inner wall of the protective cover 19, a support plate 34 installed inside the housing 33, a UV-C LED chip 35 detachably installed on the support plate 34, and a light-transmitting film 36 installed on the housing 33 for sealing the housing 33.

[0045] In this embodiment, when the user needs to disinfect the comb bar 6 inside the protective cover 19, the user first activates the disinfection device 31 through the control panel 37 on the battery box 32. After receiving electrical energy, the UV-C LED chip 35 is activated and emits short-wave ultraviolet light in all directions. The ultraviolet light penetrates the light-transmitting film 36 covering the outside of the outer shell 33 and directly irradiates and covers the outer wall surface of the comb bar 6 and the surface of the massage beads 8 inside the cavity of the protective cover 19, thereby inactivating the bacteria and microorganisms on their surface. By fixing the outer shell 33 to the inner wall of the protective cover 19, an independent and stable mounting carrier is provided for the disinfection component, so that the ultraviolet light source is integrated with the protective cover 19, eliminating the need to install additional disinfection devices in other parts of the drug delivery device.

[0046] In summary, compared with related technologies, this device, by setting a connecting cylinder 7 threaded onto the comb rod 6 and a massage bead 8 embedded therein, achieves simultaneous application of medicine and scalp massage, promoting blood circulation and improving the transdermal absorption of medicine. By setting a quantitative structure composed of a spring 10, a blocking plate 11, a blocking block 15 and a sealing sleeve 16, in conjunction with a limiting telescopic rod 14 and a rubber protective sleeve 13, it achieves automated quantitative distribution of medicine and isolates the medicine, ensuring the uniformity and repeatability of medicine output, while preventing medicine contamination.
