Description

Technical Field

[0001] This application belongs to the field of dermatological instrument technology, and more specifically, relates to a device for applying traditional Chinese medicine dermatological drugs. Background Technology

[0002] In traditional Chinese medicine (TCM) dermatology diagnosis and treatment, as well as daily care, topical medications are the primary means of treating skin conditions. TCM treatment of skin diseases often employs a combination of multiple ointments, including creams, pastes, and liniments. The effectiveness of these multi-drug combinations is closely related to the performance of the application equipment used.

[0003] Currently used application tools such as cotton swabs, scrapers, and simple applicators have significant limitations. Firstly, existing tools require individual dispensing of medication from different containers before application to the affected area, a cumbersome process, especially when using multiple medications in combination. Furthermore, precise control of the dosage for each medication is impossible, leading to discrepancies in drug ratios and affecting treatment efficacy. Improper dosage can also result in medication waste. Secondly, when using multiple medications in combination, they must be thoroughly mixed beforehand to ensure even application. Currently, manual mixing in containers before application adds extra steps and makes it difficult to achieve thorough mixing, leading to uneven drug concentrations and inconsistent efficacy, directly impacting treatment results. Summary of the Invention

[0004] Based on the above-mentioned technical problems, this application provides a traditional Chinese medicine dermatology drug application device to solve the technical problems of existing traditional Chinese medicine dermatology application tools in scenarios where multiple ointments are used in combination, such as cumbersome drug dispensing operations, inability to accurately control the amount of each drug dispensed, and the need for manual drug mixing leading to redundant operations and insufficient mixing, which in turn affects the treatment effect.

[0009] Furthermore, the connecting pipe near the central axis of the shell is defined as a rotating pipe. The two ends of the rotating pipe are rotatably connected to the partition and the medicine storage cylinder, respectively, and the top end of the rotating pipe extends through the partition into the mixing space. The stirring assembly includes a connecting ring, which is fixedly sleeved on the top end of the rotating pipe; and multiple stirring rods are evenly arranged along the circumference of the connecting ring.

[0010] Furthermore, the power unit includes a gear located between the medicine storage cylinder and the partition plate, and fixedly sleeved on the outside of the rotating tube; a slide rail fixed on the top surface of the medicine storage cylinder; and a rack slidably disposed in the slide rail and meshing with the gear, one end of the rack extending outward through the housing.

[0011] Furthermore, there are two slides and two racks, with the two slides located on the radial sides of the gear respectively; the two racks are slidably disposed in the two slides and mesh with the gear respectively; one end of each rack extends outward through both sides of the housing and is fixedly provided with a stop block; a second spring is sleeved on the outer side of each rack, and the two ends of each second spring abut against the corresponding stop block and the outer wall of the housing respectively.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0026] Please refer to the following: Figures 1 to 8 As shown, the following describes a traditional Chinese medicine (TCM) dermatology drug application device provided in an embodiment of this application. The core of this TCM dermatology drug application device lies in its integrated functions of quantitative drug dispensing, drug mixing, and precise application, solving problems such as cumbersome operation, inaccurate proportions, uneven mixing, and drug waste associated with existing application tools. It is suitable for the combined use of various dosage forms of TCM dermatology drugs, including ointments, pastes, and liniments, and caters to both clinical diagnosis and daily care needs. Its overall structure includes a shell 1, a stirring assembly 6, a drug application assembly 5, a handle 2, a quantitative drug dispensing assembly 3, a locking assembly 4, and a power unit 7.

[0027] Specifically, the housing 1 serves as the main support of the device and has a hollow internal structure. A partition 11 is fixed inside the housing 1, dividing the interior into an upper mixing space 12 and a lower installation space 13. The mixing space 12 is used to contain and mix various dermatological medications, while the installation space 13 is used to fix the application component 5. The handle 2 is detachably snapped onto one end of the housing 1 forming the mixing space 12 via a snap-fit ​​component 4. A viewing window 22 is provided on one side of the handle 2 to allow the operator to observe the medication dispensing process. The quantitative dispensing component 3 is fixed inside the handle 2, with its output end passing through the housing 1 and connecting to the mixing space 12, used to deliver a quantitative amount of medication to the mixing space 12. The stirring component 6 is rotatably mounted within the mixing space 12, and a power unit 7 is located inside the housing 1, providing driving force for the stirring component 6 to rotate. The application component 5 is fixed within the installation space 13, with its input end connected to the mixing space 12 and its output end extending outward through the installation space 13 to form an application head, used to apply the mixed medication to the patient's skin.

[0028] During implementation, multiple quantitative drugs are first accurately extracted through the quantitative drug dispensing component 3 inside the handle 2, combined with the viewing window 22 and the scale line 311. After completing the drug dispensing operation, the handle 2 is fixed to the housing 1 through the snap-fit ​​component 4. At this time, the output end of the drug dispensing component is connected to the mixing space 12 and the drug is transported to the mixing space 12. Then, the stirring component 6 is driven by the power unit 7 to operate in the mixing space 12 to fully mix the multiple drugs. The mixed drugs enter the application component 5, and the drug is applied to the patient's skin through the output end of the application component 5. The entire process realizes a continuous operation of drug dispensing, mixing and application.

[0029] In this embodiment, the quantitative drug dispensing component 3 is used for precise quantitative extraction and delivery of drugs. It includes a dispensing cylinder 31, a piston 32, and a driving component. The outer wall of the dispensing cylinder 31 is engraved with scale lines 311, which correspond to the viewing window 22 on the handle 2. The operator can intuitively read the amount of drug dispensed through the viewing window 22, providing an accurate basis for multi-drug formulation. The piston 32 is slidably disposed inside the dispensing cylinder 31 to complete the drug dispensing and delivery actions. The driving component is used to drive the piston 32 to slide along the axial direction of the dispensing cylinder 31. Specifically, the drive assembly includes a stopper rod 33 and a screw 34. The stopper rod 33 is coaxially arranged inside the dispensing cartridge 31, with one end fixedly connected to the piston 32. A sliding groove 312 is provided on the inner wall of the dispensing cartridge 31, and the stopper rod 33 slides in cooperation with the dispensing cartridge 31 through the sliding groove 312. The sliding groove 312 can restrict the rotation of the stopper rod 33, ensuring that the piston 32 always moves smoothly along a straight line. A threaded hole 331 is provided at the end of the stopper rod 33 away from the dispensing cartridge 31. The screw 34 is rotatably mounted on the handle 2, with one end passing through the threaded hole 331 and forming a screwed connection.

[0030] When dispensing the medication in a measured amount, rotating the screw 34 causes the screw 34 to drive the stopper rod 33 to slide away from the dispensing cylinder 31 via a screw connection with the threaded hole 331. This causes the stopper rod 33 to move the piston 32 synchronously, allowing the external medication to be drawn into the dispensing cylinder 31 through the injection tube 313. At this time, the operator can observe the scale line 311 through the viewing window 22 and control the number of rotations and angle of the screw 34 to precisely adjust the dispensing amount. When pushing the medication (at this time, the quantitative dispensing component 3 is connected to the mixing space 12), rotating the screw 34 in the opposite direction causes the piston 32 to move in the opposite direction, pushing the medication into the mixing space 12. It should be noted that the threaded drive has precise adjustability and self-locking characteristics. It can precisely control the dispensing amount by rotating the screw 34 to avoid deviations in the multi-drug ratio, and it can also stably fix the position of the piston 32 after dispensing to prevent medication leakage.

[0031] Preferably, one end of the dispensing cartridge 31 is connected to an injection tube 313. The free end of the injection tube 313 passes through the housing 1 and extends into the mixing space 12, allowing the drug to be directly delivered into the mixing space 12, reducing drug residue on the delivery path. Correspondingly, the piston 32 is provided with a pusher block 321 adapted to the inside of the injection tube 313 at one end. That is, the pusher block 321 can move with the piston 32 and embed itself into the injection tube 313, thereby cleaning the drug residue on the inner wall of the injection tube 313 and achieving drug residue-free delivery.

[0032] In this embodiment, the snap-fit ​​assembly 4 includes a snap-fit ​​ring 41, an arc-shaped snap-fit ​​block 42, and an elastic element 43. The snap-fit ​​ring 41 is fixed to one end of the housing 1 near the handle 2, and an annular groove 411 is formed inside the snap-fit ​​ring 41. There are multiple arc-shaped snap-fit ​​blocks 42, which are evenly arranged around the annular groove 411. The end of the arc-shaped snap-fit ​​block 42 near the inner arc surface slides through the inner wall of the annular groove 411 and can slide and extend towards the central axis of the snap-fit ​​ring 41. The elastic element 43 has an annular structure and can be an elastic rubber ring or an annular spring, elastic rope, etc., which are assembled in the annular groove 411. Its inner side abuts against the outer arc surface of each arc-shaped snap-fit ​​block 42, providing continuous radial elastic force to the arc-shaped snap-fit ​​block 42 and preventing the arc-shaped snap-fit ​​block 42 from sliding into the annular groove 411. Correspondingly, an annular groove 21 for accommodating multiple arc-shaped snap-fit ​​blocks 42 is recessed on the outer wall of the handle 2. Preferably, each arc-shaped locking block 42 has a positioning groove (not shown in the figure) on its outer surface corresponding to the elastic element 43 to prevent the elastic element 43 from detaching from the arc-shaped locking block 42. It should be noted that multiple sliding holes 412 are provided in the arc groove corresponding to multiple arc-shaped locking blocks 42. The arc-shaped locking blocks 42 are slidably disposed in the sliding holes 412, and the maximum diameter of the end of the arc-shaped locking block 42 near the outer arc surface is greater than the length of the sliding hole 412 to prevent the arc-shaped locking block 42 from detaching from the annular groove 411.

[0033] During implementation, the operator inserts the end of handle 2 into the locking ring 41, which compresses the arc-shaped locking block 42 through the outer wall of handle 2, causing the arc-shaped locking block 42 to retract into the annular groove 411. The elastic element 43 is stretched, generating a restoring force. After handle 2 is installed in place, the restoring force of the elastic element 43 pushes multiple arc-shaped locking blocks 42 to move synchronously towards the central axis, tightly abutting against the annular groove 21 on the outer wall of handle 2, thus firmly fixing handle 2. During disassembly, the operator applies outward force to pull handle 2, causing handle 2 to compress the arc-shaped locking blocks 42 and retract into the annular groove 411, allowing handle 2 to be quickly removed. In this way, multiple evenly arranged arc-shaped locking blocks 42 can achieve circumferential locking of handle 2, preventing handle 2 from loosening during operation and ensuring the stability of equipment operation.

[0034] In this embodiment, the application assembly 5 includes multiple applicators 51, evenly distributed within the installation space 13, to expand the application range per application and improve application efficiency. Each applicator 51 includes a drug reservoir 52, a connecting tube 53, an application ball 54, and a first spring 55. The top of each drug reservoir 52 is connected to the mixing space 12 via the connecting tube 53 to temporarily store the mixed drug. The bottom has an opening to communicate with the outside, and a retaining ring 521 protrudes from the inner edge of the opening. The application ball 54 is assembled inside the drug reservoir 52, and its maximum diameter is larger than the inner diameter of the retaining ring 521 but smaller than the inner diameter of the drug reservoir 52. This prevents the application ball 54 from falling off and ensures that the application ball 54 rolls flexibly. The first spring 55 is disposed inside the drug reservoir 52, with both ends abutting against the application ball 54 and the top wall of the drug reservoir 52, respectively, to provide continuous elastic support for the application ball 54. Even if the application ball 54 is constantly abutting against the retaining ring 521, the opening is closed to prevent the drug from flowing out.

[0035] Preferably, to meet the care needs of delicate skin in dermatology, the application roller 54 is made of medical-grade, food-grade soft silicone with a Shore hardness of 60 to 70, and the surface has a slightly smooth, matte finish. This material has moderate hardness, is soft and scratch-free, and can avoid secondary damage to the affected skin. At the same time, the medical-grade material has good biocompatibility, eliminating the risk of allergies. In addition, the slightly smooth, matte surface balances rolling performance and drug absorption, ensuring smooth rolling and effortless application, while also absorbing an appropriate amount of drug to avoid waste and ensure even application.

[0036] During implementation, the medication in the mixing space 12 enters each medication reservoir 52 via the connecting tube 53. When applying the medication, the application roller 54 contacts the patient's skin and applies slight pressure, causing the roller 54 to move into the medication reservoir 52 and compress the first spring 55. This creates a gap between the application roller 54 and the retaining ring 521, allowing the medication to flow out and adhere to the surface of the application roller 54, ensuring even application to the patient's skin as the roller rolls. After application, the application roller 54 detaches from the skin, the first spring 55 resets, pushing the roller against the retaining ring 521, closing the gap and stopping medication dispensing. This design, by using applicators 51, synchronizes medication dispensing and application, simplifying operation and preventing medication leakage during non-application periods. The rolling application method also minimizes skin irritation, meeting dermatological care needs. Furthermore, the evenly distributed design of multiple applicators 51 improves application efficiency, and the intermittent dispensing method ensures uniform medication dosage, preventing uneven efficacy due to excessive or insufficient local medication.

[0037] In this embodiment, the connecting pipe 53 near the central axis of the housing 1 is defined as the rotating pipe 531. The two ends of the rotating pipe 531 are rotatably connected to the partition 11 and the medicine storage cylinder 52 respectively through existing sealed bearings (not shown in the figure), and the top end of the rotating pipe 531 extends through the partition 11 into the mixing space 12. It should be noted that other connecting pipes 53 can be fixed or rotatably connected, and there is no limitation here.

[0038] The stirring assembly 6 includes a connecting ring 61 and stirring rods 62. The connecting ring 61 is located within the mixing space 12 and is fixedly sleeved on the top of the rotating tube 531. Multiple stirring rods 62 are evenly arranged around the circumference of the connecting ring 61. Specifically, each stirring rod 62 includes a horizontal bar 621 and multiple vertical bars 622. One end of the horizontal bar 621 is fixedly connected to the connecting ring 61, and the other end extends radially away from the connecting ring 61. Multiple vertical bars 622 are spaced apart axially along the horizontal bar 621, and the bottom end of each vertical bar 622 is fixedly connected to the horizontal bar 621.

[0039] The power unit 7 includes a gear 71, a slide rail 72, and a rack 73. The gear 71 is located between the medicine storage cylinder 52 and the partition plate 11, and is fixedly sleeved on the outside of the rotating tube 531, so that the gear 71 rotates synchronously with the rotating tube 531. The slide rail 72 is fixed on the top surface of the medicine storage cylinder 52, and the rack 73 is slidably disposed in the slide rail 72 and meshes with the gear 71, so as to limit the sliding direction of the rack 73 by the slide rail 72. In practice, by pulling or pushing the rack 73, the gear 71 meshing with it can be driven to rotate, which in turn drives the rotating tube 531 to rotate. In this way, the rotation of the rotating tube 531 drives the stirring assembly 6 to rotate, thereby mixing the medicine in the mixing space 12.

[0040] Preferably, in order to improve transmission stability and stirring effect, two slides 72 and racks 73 are provided and arranged symmetrically along the radial direction of gear 71. One end of each rack 73 extends outward through both sides of the housing 1 and a stop block 74 is fixed at the end. A second spring 75 is sleeved on the outside of each rack 73, and the two ends of the second spring 75 abut against the corresponding stop block 74 and the outer wall of the housing 1, respectively.

[0041] During implementation, the operator pushes any one rack 73 or both racks 73 simultaneously towards the inside of the housing 1. The rack 73 slides linearly along the slide rail 72. Through the meshing of the rack 73 and the dimension 71, the gear 71 is driven to rotate. The gear 71 drives the rotating tube 531 to rotate synchronously. The rotating tube 531 drives the connecting ring 61 and the stirring rod 62 to rotate within the mixing space 12, thereby achieving drug stirring. It should be noted that when the rack 73 is pushed, the stop block 74 moves towards the housing 1 along with the rack 73, compressing the second spring 75. By controlling the pushing speed of the rack 73, the rotation speed of the gear 71 can be adjusted. After the rack 73 is released, the restoring force of the second spring 75 pushes the stop block 74, causing the rack 73 to return to its original position towards the outside of the housing 1. The gear 71 rotates in the opposite direction, and the stirring rod 62 achieves reverse stirring. This allows for bidirectional stirring via the automatic reset of the second spring 75, eliminating the need for manual reset of the rack 73. This simplifies operation and effectively breaks up easily clump-forming drugs, solving the problem of uneven mixing during manual operation. Furthermore, the manual transmission eliminates the need for electronic control components, simplifying the structure, reducing costs, improving equipment portability, and making it suitable for mobile medical scenarios.

[0042] In this embodiment, the partition 11 includes a base plate 111 and an annular plate 112. The bottom end of the annular plate 112 is fixedly connected to the outer edge of the base plate 111, and the top end of the annular plate 112 is fixedly connected to the top wall of the housing 1. The inner wall of the annular plate 112 slopes downwards from top to bottom towards the center of the base plate 111. This sloped structure of the inner wall of the annular plate 112 guides the drug in the mixing space 12 to converge towards the center of the base plate 111. This allows the stirred drug to flow smoothly along the slope to the central area of ​​the base plate 111 under its own gravity and the guiding effect of the slope, and then enter the application assembly 5. This prevents the drug from depositing in the corners and gaps of the partition 11, reducing drug waste.

[0043] In a specific implementation of the present invention, the operator holds the detachable handle 2 and uses the quantitative drug dispensing component 3 inside the handle 2, combined with the viewing window 22 and the scale line 311, to accurately extract various required drugs. After the drugs are extracted, the piston 32 is fixed by means of the thread transmission self-locking characteristic of the screw 34 and the threaded hole 331 to prevent the drugs from leaking out. Then, the handle 2 is firmly fixed to the housing 1 via the snap-fit ​​assembly 4. At this time, the injection tube 313 is inserted into the housing 1, so that the quantitative drug dispensing assembly 3 is connected to the mixing space 12. Then, the screw 34 is rotated to push the quantitative drug into the mixing space 12. Then, the rack 73 of the power unit 7 is pushed to drive the stirring assembly 6 to rotate in both directions, so that the multiple drugs are fully mixed. The mixed drugs enter the drug storage cylinder 52 of the drug application assembly 5 through the connecting tube 53. At this time, the operator holds the handle 2 and aligns the application roller 54 with the patient's skin, applies slight pressure to make the drug flow out from the gap between the roller and the retaining ring 521. The drug is evenly applied to the skin by rolling the application roller 54. After the application is completed, the spring returns to its original position to close the drug dispensing gap and stop the drug dispensing.
