Description

Technical Field

[0001] This utility model relates to the field of devices for delivering media to the human body, specifically to a portable ultrasonic herbal medicine delivery device for hair growth. Background Technology

[0002] In the field of scalp health management, including hair loss treatment, scalp nutrition supplementation, and scalp inflammation care, the effectiveness of topical liquid medications directly determines the treatment and care results. Currently, the widely used method is the traditional scalp medication application method of "medication spraying + hand massage," where the user sprays the liquid directly onto the scalp surface and then massages the sprayed area with their fingers. However, this method has the following problems in practical application:

[0003] 1. Low retention rate and insufficient safety. After the medication is sprayed onto the scalp, due to the curved shape of the scalp, the effects of gravity, and the fluidity of the medication itself, it is prone to unintended flow within a short period of time if the user does not massage it in time. For example, medication sprayed towards the forehead tends to flow towards the eyelids and cheeks, while medication sprayed towards the top of the head tends to flow towards the back of the head. This results in a large amount of medication not remaining in the target area, increasing the cost of medication and requiring additional cleaning of medication residue in non-target areas. At the same time, some scalp medications are irritating to facial skin, eyelid mucous membranes, etc. When the flowing medication comes into contact with these areas, it can easily cause redness, swelling, itching, and other discomfort, reducing the safety of use.

[0004] 2. Poor drug penetration efficiency. The force of hand massage only acts on the surface of the scalp's stratum corneum, primarily through friction, which cannot open the lipid barrier of the stratum corneum. This makes it difficult for the drug to penetrate to the hair follicle root. Most of the drug remains on the outer side of the stratum corneum and is eventually lost through daily washing and sweat secretion, resulting in low drug absorption. Especially in the case of hair loss treatment, there is also the problem of slow effect of single-drug treatment. Due to the limited passive penetration efficiency of traditional methods, the large molecules such as active ingredients in traditional Chinese medicine have difficulty quickly breaking through the stratum corneum to reach the hair follicle, resulting in a long treatment cycle and slow treatment effect.

[0005] 3. Uneven application of medication. The coverage area of ​​the medication spray is limited. When applying medication to a large area, it is necessary to repeat the spraying and massage operations in different areas. During this process, gaps without medication may appear between sprayed areas due to the deviation of the area division, and excessive accumulation of medication may occur in adjacent areas due to overlapping operations. Both situations will lead to uneven application of medication, which will affect the treatment effect of the scalp. Utility Model Content

[0006] The present invention aims to provide a portable ultrasonic herbal medicine delivery device to solve the problems of easy waste of medicine, poor absorption of medicine and uneven application of medicine in existing medicine delivery methods.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A portable ultrasonic herbal medicine delivery device for hair growth includes a main body containing a miniature peristaltic pump. The pump's inlet is connected to an inlet pipe, and its outlet is connected to an outlet pipe. The pump is electrically connected to a controller, which has buttons and indicator lights located on the main body. An ultrasonic generator is also located within the main body, connected to an ultrasonic transducer. The transducer's oscillation radiation surface faces the bottom of the main body. A battery is also located within the main body. The controller, indicator lights, ultrasonic generator, and ultrasonic transducer are all electrically connected to the battery. A charging port is located on the main body.

[0009] The top of the machine body is threaded with a medicine bottle, and the center of the top of the machine body is set with a liquid inlet connector. One end of the liquid inlet connector is located inside the machine body and is connected to the liquid inlet pipe. The other end of the liquid inlet connector protrudes from the top surface of the machine body and the port is symmetrically sealed with two elastic sealing bladders. The sealing bladders are connected to the air passage opened in the inner wall of the liquid inlet connector. When there is no force, the sealing bladders are in an expanded state to close the port of the liquid inlet connector. When there is force, the gas in the sealing bladders can be squeezed into the air passage. The center of the top of the medicine bottle is set with a liquid inlet nozzle that can be inserted into the liquid inlet connector. The free end of the liquid inlet nozzle is plugged with a sealing plug.

[0010] The bottom of the machine body is threaded with a comb head, and the bottom of the comb head is provided with several hollow comb teeth. The free end of the comb teeth is equipped with a ball bearing. The comb head is equipped with a medicine tank, and the comb teeth are connected to the medicine tank. The bottom center of the machine body is provided with a liquid outlet connector. One end of the liquid outlet connector is located inside the machine body and is connected to the liquid outlet pipe. The other end of the liquid outlet connector protrudes from the bottom surface of the machine body and is provided with a sealing ring on the inner wall. The top center of the comb head is provided with a liquid outlet spout that can be inserted into the liquid outlet connector and is connected to the medicine tank.

[0011] Preferably, as an improvement, the comb teeth include an insulating inner layer and a conductive outer layer. A wire is provided inside the comb head, and the wire is fixedly connected to the conductive outer layer of each comb tooth. A conductive plug is provided on the top side of the comb head, and the conductive plug is connected to the wire inside the comb head. A micro-current generator is provided inside the machine body, and the micro-current generator is electrically connected to the battery and the controller. A conductive socket is provided on the bottom side of the machine body, and the micro-current generator is electrically connected to the conductive socket through the wire provided inside the machine body. When the comb head is tightened, the conductive plug can be tightly inserted into the conductive socket. An insulating coating is provided on the base of the conductive plug and the surface of the conductive socket.

[0012] Preferably, as an improvement, a current regulator is installed inside the machine body. The current regulator is electrically connected to the battery and the controller. The current regulator is electrically connected to the conductive socket through a wire. Red LED beads are installed in the gaps between the comb teeth. The red LED beads are electrically connected to the conductive plug through a wire.

[0013] Preferably, as an improvement, the free ends of the comb teeth form an arc surface that is concave towards the inside of the body.

[0014] Preferably, as an improvement, the medicine bottle is a transparent medicine bottle.

[0015] Preferably, as an improvement, the medicine bottle is provided with graduation lines.

[0016] The beneficial effects of this plan are:

[0017] 1. This solution precisely controls the pumping rate of the herbal medicine solution using a micro-peristaltic pump. Combined with the built-in ball bearing structure at the comb's end, the ball bearing naturally rolls with the comb's movement during application, dispensing a measured amount of medicine. This avoids the problems of medicine accumulation or leakage that occur with traditional manual application, achieving uniform coverage of the target area on the scalp. Simultaneously, the pumped medicine delivery creates unidirectional flow pressure in the medicine delivery path, effectively preventing the delivered medicine from flowing back into the bottle and contaminating the remaining medicine. Furthermore, the rolling of the ball bearing provides a gentle physical massage to the scalp, relaxing scalp muscles, promoting local blood circulation, and breaking the static tension on the scalp's surface, creating favorable conditions for subsequent medicine penetration and further improving the initial absorption efficiency of the medicine in the superficial layers of the scalp.

[0018] The medicine bottle and the machine body adopt a threaded, detachable connection structure. In practical applications, the prepared Chinese medicine solution can be pre-packaged in a disposable sterile medicine bottle. When using it, the user only needs to align the disposable medicine bottle with the machine body interface and tighten it by rotating it. There is no need to manually pour out the medicine solution, simplifying the operation process. To achieve automatic liquid flow, there is an inlet connector at the center of the machine body, and an inlet spout is correspondingly located at the center of the bottom of the medicine bottle. When the medicine bottle is tightened, the inlet spout will naturally insert into the inlet connector along the central axis, automatically completing the sealing connection between the medicine bottle and the inlet tube inside the machine body. The symmetrical design at the center can prevent misalignment when the medicine bottle is rotated, ensuring accurate alignment every time it is installed.

[0019] In addition, the inlet connector port is equipped with two sealing bladders that communicate with the air passage inside the inlet connector. When no force is applied, the gas is located inside the two sealing bladders. When the two sealing bladders are inflated, they seal the port of the inlet connector, which can effectively prevent foreign objects or dust from entering the machine body through the inlet connector. When installing the medicine bottle, the inlet spout on the medicine bottle can squeeze the two sealing bladders inward when inserted into the inlet connector, forcing the gas in the two sealing bladders into the air passage, thus allowing it to be smoothly inserted into the inlet connector. After insertion, the sealing bladders are squeezed between the inlet connector and the inlet spout, which can also improve the connection and sealing between the two. After the inlet spout is removed, the elastic sealing bladders return to their original position under their own elasticity, and the gas in the air passage flows back into the sealing bladders, which can seal the port of the inlet connector again.

[0020] 2. The use of disposable sterile medicine bottles enables convenient operation of disassembling and using the medicine bottles immediately and discarding them after use. This avoids contact between the medicine liquid and external contaminants from the source, solves the risk of bacterial growth caused by manual medicine addition and incomplete cleaning of medicine bottles in traditional medicine dispensers, and greatly improves the sterility and safety of medicine use.

[0021] 3. The device integrates an ultrasonic generator and an ultrasonic transducer. During operation, the ultrasonic generator outputs an electrical signal of a specific frequency, which is converted into high-frequency mechanical vibration by the ultrasonic transducer and transmitted to the comb teeth. When this high-frequency vibration acts on the scalp skin tissue, it will produce a "cavitation effect" in the intercellular spaces of the stratum corneum. That is, tiny, instantaneous vacuoles are formed. The local pressure generated when the vacuoles rupture can open the lipid barrier of the stratum corneum and form temporary microchannels. These channels can directly provide a penetration path for macromolecular Chinese medicine ingredients, actively "pushing" them to the hair follicle roots deep in the skin. Compared with the traditional manual application method that relies on passive penetration, it significantly shortens the time for the medicine to reach the target point, increases the absorption efficiency by several times, and reduces the waste of medicine on the scalp surface.

[0022] 4. The transparent medicine bottle allows users to visually observe the remaining amount of Chinese medicine liquid inside and promptly determine whether it needs to be replenished or replaced. Clear graduation lines are also engraved on the side of the bottle, allowing users to accurately control the volume of medicine taken or remaining each time, avoiding instability in treatment effects due to errors in dosage estimation. It also facilitates recording the medication cycle, improving the standardization and controllability of medication use.

[0023] 5. The comb teeth at the bottom of the comb are of different lengths. The teeth in the center of the comb are shorter and gradually increase in length as they extend to the outer area of ​​the comb. This makes the free ends (the ends that contact the scalp) of all the comb teeth form an arc-shaped surface that is concave towards the inside of the body. This arc-shaped surface is highly compatible with the spherical curvature of an adult's head, allowing the comb teeth to better fit the user's scalp when applying medicine.

[0024] 6. This solution integrates a microcurrent generator within the device. The outer layer of the comb teeth uses a conductive outer layer as electrodes. When the comb teeth contact the scalp, the microcurrent forms a local current loop on the scalp surface. On one hand, the current stimulates and activates the metabolic activity of hair follicle cells, promoting the absorption of effective components of traditional Chinese medicine by the hair follicles. On the other hand, the microcurrent can also change the potential difference of the scalp's stratum corneum, reducing the penetration resistance of macromolecular components, and forming a synergistic effect with the ultrasound function to further enhance the treatment effect. Simultaneously, the comb head and the device adopt a centrally positioned detachable structure. A liquid outlet is located at the center of the top of the comb head, and a corresponding liquid outlet connector is located at the bottom of the device. When the comb head is tightened, the two automatically connect to open the liquid channel. Additionally, an arc-shaped conductive plug is located on the top side wall of the comb head, and a corresponding conductive socket is located on the bottom side wall of the device. Both the base of the conductive plug and the surface of the conductive socket are treated with an insulating coating, leaving only the contact area conductive. When the comb head is tightened along the threads, the conductive plug automatically slides into the conductive socket for a tight fit, achieving automatic energization of the microcurrent loop, making operation simple.

[0025] 7. This solution embeds red light beads in the gaps between the comb teeth to form an infrared therapy module. The infrared beads inside the comb are electrically connected to the conductive plug at the top of the comb via wires, and the conductive socket at the bottom of the device is connected to the current regulator inside the device via wires. When the comb is tightened along the threads, the conductive plug of the comb automatically inserts into the conductive socket of the device and achieves stable contact, automatically powering on the infrared module without the need for additional manual wiring. After power-on, the controller sends a command to the current regulator according to a preset mode, and the current regulator outputs a stable current to the infrared beads, ensuring that the infrared beads emit infrared light with uniform power. The infrared light can penetrate the scalp surface and reach the hair follicle area, activating the hair follicles through photobiological regulation. At the same time, the infrared light can also dilate scalp capillaries and improve local microcirculation. Combined with the penetration of traditional Chinese medicine liquid, roller massage, ultrasonic penetration promotion, and microcurrent stimulation, it enhances the overall effect of hair regrowth treatment.

[0035] The following detailed description illustrates the specific implementation method:

[0036] Example 1

[0037] like Figure 1 and Figure 2 As shown, the portable ultrasonic herbal medicine delivery device includes a cylindrical body 1. An ergonomic handle 8 is integrally formed on one side of the body 1, with an anti-slip textured inner side for a secure grip. A miniature peristaltic pump 10 (model Lange CM200-2B) is fixed inside the body 1. The inlet of the miniature peristaltic pump 10 is tightly connected to a food-grade silicone inlet tube 9 via a stainless steel hose clamp, and the outlet of the miniature peristaltic pump 10 is also tightly connected to a food-grade silicone outlet tube 11 via a stainless steel hose clamp. The miniature peristaltic pump 10 is electrically connected to a controller via wires. The controller is a PLC or microcontroller, and is electrically connected to a button 7 and an indicator light 6 via wires. Both the button 7 and the indicator light 6 are embedded in the side of the body 1. An ultrasonic generator 13, model TCT40-16T, is fixed inside the body 1 near the comb head 3. The ultrasonic generator 13 is connected to a piezoelectric ceramic ultrasonic transducer 15 via a wire 14. The ultrasonic transducer 15 is attached to the inner wall of the bottom of the body 1 near the comb head 3 with the oscillation radiation surface facing downwards. A battery is installed at the bottom of the body 1. The battery is a 2000mAh 18650 rechargeable lithium battery. The controller, indicator light 6, ultrasonic generator 13, and ultrasonic transducer 15 are all electrically connected to the battery via wires. A charging port is opened on the side of the body 1. The charging port is a Type-C charging port and is equipped with a silicone dust plug to prevent dust and medicine from entering.

[0038] Combination Figure 3 As shown, a transparent PET medicine bottle 2 is detachably mounted on the top of the machine body 1. The outer side of the medicine bottle 2 has clear milliliter (mL) graduations printed on it, with a minimum graduation interval of 0.5mL, allowing for precise control of the medication volume. The medication is pre-packaged in a disposable sterile transparent medicine bottle 2, which is a single-piece structure. Specifically, the top of the machine body 1 has a threaded mounting groove 18, into which the medicine bottle 2 is detachably threaded. A 304 stainless steel inlet connector 17 is integrally formed vertically at the center of the top of the machine body 1. One end of the inlet connector 17 extends into the machine body 1 and is tightly fitted and connected to the inlet tube 9 via a stainless steel hose clamp. The other end of the inlet connector 17 protrudes from the top surface of the machine body 1. A PET inlet nozzle 16 is integrally formed at the center of the top of the medicine bottle 2 (the medicine bottle 2 is inverted in the figure, shown at the bottom) using an injection molding process. The free end of the inlet nozzle 16 (when not inserted) is plugged with a rubber sealing plug, and the free end of the inlet nozzle 16 has a taper for easy insertion into the inlet connector 17. Combination Figure 4 As shown, two semi-circular elastic sealing bladders 26 are glued and fixed at the port of the liquid inlet connector 17. The sealing bladders 26 are made of wear-resistant airbag material in the prior art. Both sealing bladders 26 are connected to air passages (not shown in the figure) opened in the inner wall of the liquid inlet connector 27. When no force is applied, the two sealing bladders 26 are filled with gas and are in an expanded state to seal the port of the liquid inlet connector 17. Figure 4 As shown in the diagram, when squeezed by external force, the gas inside the two sealing bladders 26 can be squeezed into the airway. After the external force is removed, the two sealing bladders 26 can reset under their own elasticity and re-inhale the gas in the airway to expand and seal the port of the liquid inlet connector 17.

[0039] A circular comb head 3 is threaded onto the bottom of the body 1. Several mounting holes are evenly spaced on the bottom of the comb head 3, and hollow comb teeth 4 are fixed within these holes. A medical-grade stainless steel ball bearing 5, capable of 360° rotation, is embedded in the free end (the end that contacts the scalp) of each comb tooth 4. A medicine reservoir 12 is located inside the comb head 3, and the hollow channel of each comb tooth 4 communicates with the medicine reservoir 12. Specifically, a 304 stainless steel liquid outlet connector 19 is integrally formed vertically at the center of the bottom of the body 1. One end of the liquid outlet connector 19 extends into the body 1 and is tightly fitted and connected to the liquid outlet tube 11 via a stainless steel hose clamp. The other end of the liquid outlet connector 19 protrudes from the bottom surface of the body 1, and a silicone sealing ring is embedded in the inner wall near the port. An integrally formed liquid outlet nozzle 20, capable of being inserted into the liquid outlet connector 19, is located at the center of the top of the comb head 3. The free end of the liquid outlet nozzle 20 is tapered for easy insertion into the liquid outlet connector 19, and the liquid outlet nozzle 20 communicates with the medicine reservoir 12.

[0040] In practical application, the disposable medicine bottle 2 is screwed into the threaded mounting groove 18 on the machine body 1. When the medicine bottle 2 is tightened, the liquid inlet spout 16 on the medicine bottle 2 is also inserted into the liquid inlet connector 17 on the machine body 1, realizing automatic connection between the medicine bottle 2 and the liquid inlet tube 9. During the tightening process of the medicine bottle 2, the liquid inlet spout 16 is gradually inserted into the liquid inlet connector 17. In the initial state, the two sealing plates 26 are not under force and are in an expanded state, sealing the port of the liquid inlet connector 17. Figure 4 (As shown in the diagram), this prevents foreign objects and dust from entering the inlet connector 17. When the inlet nozzle 16 is inserted into the inlet connector 17, the two sealing bladders 26 are squeezed into the inlet connector 17 by the inlet nozzle 16, and the gas inside is squeezed into the air passage. The two sealing bladders 26 gradually deflate and are eventually squeezed between the inlet nozzle 16 and the inlet connector 17, becoming a sealing element that seals the gap between the two, improving the connection sealing performance. When the inlet nozzle 16 is removed, the two sealing bladders 26 can expand and return to their initial state under their own elasticity. The gas in the air passage flows back into the sealing bladders 26, and the sealing bladders close the port of the inlet connector 17 again.

[0041] After the medicine bottle 2 is installed, press and hold button 7 to turn on the device, then press and hold button 7 briefly to select the mode. There are three modes: mode 1 is ultrasonic with intermittent drug dispensing, mode 2 is ultrasonic with continuous drug dispensing, and mode 3 is ultrasonic vibration only. The indicator light 6 corresponds to different colors for different modes. For example, mode 1 corresponds to white, mode 2 corresponds to yellow, and mode 3 corresponds to blue. The indicator light 6 can also indicate the battery level. When the battery is full, the indicator light 6 is green. When charging, the green light flashes. When the battery is low, the indicator light is red.

[0042] This embodiment uses Mode 1 as an example. A short press of button 7 selects Mode 1, and button 7 sends a signal to the controller. The controller then controls the micro-peristaltic pump 10 to intermittently pump the medication through the dispensing tube 11, while simultaneously controlling the ultrasonic generator 13 and ultrasonic transducer 15 to operate. The user holds the handle 8 and places the device 1 on their head, gently pressing the comb teeth 4 onto the scalp and moving them slowly. The rolling balls 5 carry the medication out of the scalp, and the ultrasonic waves promote absorption. When needed, the comb head 3 can be unscrewed from the device 1 for disinfection, wiping, or replacement. When in use, it is screwed back onto the device 1. After the comb head 3 is screwed back onto the device 1, the dispensing nozzle 20 on the comb head 3 can be inserted into the dispensing connector 19 at the bottom of the device, achieving automatic connection between the comb head 3 and the dispensing tube 11, making operation convenient.

[0043] Example 2

[0044] The difference between this embodiment and embodiment 1 is that the comb teeth 4 are set with differentiated lengths. The comb teeth 4 located in the central area of ​​the comb head 3 are shorter, and the length of the comb teeth 4 gradually increases as it extends to the outer area of ​​the comb head 3. This makes the free ends (ends that contact the scalp) of all the comb teeth 4 together form an arc-shaped surface that is concave towards the inside of the body 1, so that the comb teeth 4 can better fit the user's scalp when applying medicine.

[0045] Example 3

[0046] like Figure 6 and Figure 7 As shown, the difference between this embodiment and Embodiment 2 is that the comb teeth 4 include an insulating inner layer 21 and a conductive outer layer 22. The insulating inner layer 21 is made of medical-grade PP plastic, and the conductive outer layer 22 is made of 316L stainless steel. The conductive outer layer 22 tightly wraps around the outside of the insulating inner layer 21. Wires are laid inside the comb head 3 (outside the medicine compartment 12) and welded to the conductive outer layer 22 at the root of each comb tooth 4, with the fixing points sealed to prevent leakage. A brass conductive plug 24 is embedded on the top side of the comb head 3 (near the threaded connection). One end of the conductive plug 24 is connected to the wires inside the comb head 3 via a crimp terminal, and the other end protrudes from the surface of the comb head 3. The conductive plug 24 is wrapped with an insulating layer, leaving only the contact area exposed. A microcurrent generator of model XR2206 is fixed inside the body 1, and the microcurrent generator is connected to the battery and controller via wires. An arc-shaped conductive socket 23 is provided on the bottom side of the body 1 (corresponding to the position of the conductive plug 24 of the comb 3). The inner wall of the conductive socket 23 is made of phosphor bronze, which is elastic and ensures a tight contact. The inside of the conductive socket 23 is connected to the signal output terminal of the micro-current generator through a wire. The outer surface of the conductive socket 23 (outer side of the body 1) is coated with an insulating layer, leaving only the conductive area on the inner wall of the conductive socket 23.

[0047] In this embodiment, when the comb head 3 is tightened, the conductive plug 24 on the comb head 3 will automatically slide into and tightly insert into the conductive socket 23 on the body 1, realizing the electrical connection between the comb head 3 and the microcurrent generator. When needed, the corresponding mode can be selected by briefly pressing the button 7. The controller will start the microcurrent generator to deliver a microcurrent. The microcurrent is transmitted to the scalp through the comb teeth 4, increasing the microcurrent penetration and stimulation function and improving the absorption of the medicine.

[0048] Example 4

[0049] like Figure 8 As shown, the difference between this embodiment and embodiment 3 is that a current regulator is provided inside the body 1. The current regulator is electrically connected to the battery and controller through wires. The current regulator is also electrically connected to the conductive socket 23 through wires. Red light beads 25 are installed in the gaps of the comb teeth 4. The red light beads 25 are 650nm wavelength surface-mount ceramic substrate infrared LEDs. The red light beads 25 are electrically connected to the conductive plug 24 through wires.

[0050] In this embodiment, when the comb head 3 is tightened, the conductive plug 24 on the comb head 3 is inserted into the conductive socket 23 on the body 1, which also enables electrical connection between the red light bulb 25 and the current regulator. When needed, the corresponding mode can be selected by briefly pressing the button 7, and the controller controls the current regulator to output a stable current to the red light bulb 25 to achieve infrared phototherapy for hair growth.
