Description

Technical Field

[0001] This invention relates to the field of medical or daily care products technology, specifically to an anti-itch device with a replaceable medicated core. Background Technology

[0002] In the treatment or daily care of skin diseases, patients often scratch their skin with their fingernails due to itching. This damages the skin barrier, which in turn aggravates itching and infection, leading to thickened skin and pigmentation, creating a vicious cycle of "itching-scratching-more itching." Existing topical anti-itch tools are mostly made of bamboo or wood, with simple structures that are prone to mold growth, and they only relieve itching through a single physical stimulus of parallel friction against the skin. This device uses a traditional Chinese medicine formula commonly used by renowned traditional Chinese medicine practitioners to create a herbal core. It can relieve itching through the herbal medicine and also combat itching through the physical methods of vertical pressure and horizontal friction against the skin.

[0003] Both of the above methods suffer from low efficiency and insufficient ease of use, especially for hard-to-apply areas such as the back. Therefore, there is an urgent need for a new type of anti-itch device that provides an effective solution to the shortcomings of existing technologies. Summary of the Invention

[0004] The purpose of this invention is to provide an antipruritic device with a replaceable medicated core to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An anti-itch device with replaceable medicated cores includes a housing, a handle, and a core mounting plate:

[0007] The grip and the core mounting plate are located at the top and bottom of the housing, respectively; The bottom of the core mounting plate is provided with at least one mounting groove, in which a core can be detachably mounted and can roll within the mounting groove; The surface of the core is provided with drug components that can be released through contact.

[0008] Furthermore, the mounting groove is a hemispherical groove structure, and the core is a spherical structure;

[0009] The mounting slot is surrounded by an insertion interface, which is detachably connected to the claw on the retainer. The retainer has a circular structure. The end of the claw away from the retainer is provided with an elastic wedge-shaped buckle. The elastic opening end of the wedge-shaped buckle is provided with a limiting groove. The wedge-shaped buckle is inserted into the insertion interface. The insertion interface is provided with a limiting protrusion that engages with the limiting groove.

[0010] Furthermore, a ball groove is provided at the top of the mounting groove, in which a ball is rolled and installed, with the ball part protruding from the ball groove. A spring hole is also provided in the ball groove, and a spring is placed in the spring hole. The spring is used to provide downward pressure to the ball.

[0011] Furthermore, the core includes a non-drug-supported sphere core, on the outer circumferential surface of which a drug layer of a certain thickness is attached. The drug layer can be a dense spherical solid made from a commonly used traditional Chinese medicine antipruritic formula ground into powder and mixed with a natural binder (elm bark powder, honey, etc.), and then processed through rolling, air-drying and curing, polishing and grinding.

[0012] Furthermore, a columnar handle is detachably connected to the grip, and a handle is provided at the end of the handle away from the grip.

[0013] Furthermore, the grip is provided with a threaded hole, and a screw is provided at the end of the handle away from the handle, the screw being threadedly connected to the threaded hole.

[0014] Furthermore, the handle is a telescopic structure.

[0015] Furthermore, the drug layer is a friction-release solid drug bead incorporating traditional Chinese medicine antipruritic ingredients.

[0016] Furthermore, an ultraviolet sterilization device is also provided on the inner wall of the mounting groove.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves both traditional Chinese medicine and physical itch relief through a rollable medicated core, eliminating the need for direct finger contact with the medication and affected area, ensuring cleanliness and reducing the risk of cross-infection. The medicated core and mounting slot are detachably connected, facilitating replacement when the medication runs out or needs to be changed to a different medication, making operation convenient and improving the device's practicality and flexibility. The invention utilizes a snap-fit ​​connection structure between the retainer and the insertion interface, enabling quick installation and removal of the medicated core, simplifying operation. Simultaneously, the retainer effectively prevents the medicated core from falling off during use, ensuring the stability of the medicated core's operation and making the itch relief process smoother and more controllable.

[0018] 2. This invention utilizes an elastic compression structure composed of springs and ball bearings to eliminate the gap between the medication core and the mounting groove, preventing the core from wobbling during rolling and improving rolling stability. Simultaneously, this structure can adapt to minute changes in the core diameter, ensuring the core maintains appropriate contact pressure with the skin, resulting in more even and continuous medication application. 3. This invention employs a structure that supports the separation of the core and the drug layer, simplifying the manufacturing process of the drug core and reducing production costs. The core can be made of lightweight and inexpensive materials, with the drug only attached to the outer layer, thus avoiding waste of drug materials.

[0019] 4. This invention significantly expands the reach of the device through a detachable, extended handle, allowing users to easily apply the product to areas difficult to reach with their hands, such as the back and legs, making it particularly suitable for the elderly or those with mobility issues. Combined with the anti-itch powder made from traditional Chinese medicine ingredients, it achieves a itch-relieving effect. The extendable design further enhances the flexibility of length adjustment, adapting to the needs of different heights and usage scenarios. The threaded connection is secure and reliable, and it is easy to store and carry after disassembly.

[0020] 5. In this invention, an ultraviolet sterilization device is also provided on the inner wall of the mounting groove, which can sterilize the drug core in the mounting groove. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1 Please see Figure 1 and Figure 2An anti-itch device with a replaceable medicated core includes a housing 1, a handle 2, and a core mounting plate 3. The handle 2 and the core mounting plate 3 are located at the top and bottom of the housing 1, respectively. The handle 2 is used for the user to hold the device, and the core mounting plate 3 is used to mount the application component.

[0025] The bottom of the core mounting plate 3 is provided with at least one mounting groove 301, in which a core 4 can be detachably mounted. After installation, the core 4 can roll freely within the mounting groove 301. The surface of the core 4 is provided with a drug component that can be released through contact.

[0026] The drug layer 402 is a friction-release solid drug bead incorporating traditional Chinese medicine antipruritic ingredients.

[0027] Working principle: During use, the user holds the handle 2 and applies the medication core 4 to the skin surface where medication needs to be applied. Through a moving device, the medication core 4 rolls within the mounting slot 301, evenly transferring the medication components on its surface to the skin. As the medication core 4 rolls, the medication components on its surface are gradually consumed like chalk, evenly coating the skin and releasing the antipruritic herbal ingredients. In actual use, the antipruritic herbal ingredients can be used as the main medication, achieving a good and safe antipruritic effect. When the medication on the surface of the medication core 4 is exhausted or when it needs to be replaced with another medication, the medication core 4 can be removed from the mounting slot 301 and replaced with a new medication core.

[0028] This embodiment uses a rollable medicated core to apply the medication, eliminating the need for direct contact between fingers and the medication and affected area, ensuring cleanliness and reducing the risk of cross-infection. The medicated core and the mounting slot are detachably connected, making it easy to replace when the medication runs out or when a different medication is needed. This convenient operation improves the practicality and flexibility of the device.

[0029] Example 2 This embodiment further defines the installation and fixing method of the core 4 based on embodiment 1.

[0030] Please see Figures 1 to 3 The mounting groove 301 is a hemispherical groove structure, and the corresponding core 4 is a spherical structure. The two work together to allow the core 4 to roll in multiple directions. An insertion interface 302 is provided around the mounting groove 301. The insertion interface 302 is detachably connected to the claw 501 on the retainer 5. The retainer 5 is an annular structure used to support the core 4 from below. The end of the claw 501 away from the retainer 5 has an elastic wedge-shaped buckle 502, and the elastic open end of the wedge-shaped buckle 502 has a limiting groove 503. The insertion interface 302 has a limiting protrusion (not shown in the figure) that engages with the limiting groove 503.

[0031] Working principle: When installing the core 4, first place the spherical core 4 into the hemispherical mounting groove 301. Then, align the claws 501 of the retainer 5 with the insertion interfaces 302 around the mounting groove 301 and push them upwards. During insertion, the wedge-shaped latches 502 at the front end of the claws 501 are compressed and undergo elastic deformation. After passing through the insertion interface 302, the wedge-shaped latches 502 return to their original position, and their limiting grooves 503 engage with the limiting protrusions in the insertion interface 302, thereby fixing the retainer 5 and confining the core 4 between the mounting groove 301 and the retainer 5, allowing it to roll freely. To disassemble, press the wedge-shaped latches 502 to deform them and disengage them from the limiting protrusions, then remove the retainer 5 and take out the core 4.

[0032] This embodiment utilizes a snap-fit ​​connection structure between the retainer and the insertion interface to achieve quick installation and removal of the medication core, simplifying operation. Simultaneously, the retainer effectively prevents the medication core from falling off during use, ensuring the stability of the medication core's operation and making the application process more reliable.

[0033] Example 3 This embodiment optimizes the rolling smoothness of the core 4 based on embodiment 2.

[0034] Please see Figure 5 The top of the mounting groove 301 is provided with a ball groove 303, in which a ball 305 is rotatably mounted and partially protrudes from the ball groove 303. A spring hole is also provided in the ball groove 303, in which a spring 304 is placed. One end of the spring 304 abuts against the bottom of the spring hole, and the other end abuts against the ball 305.

[0035] Working principle: After the drug core 4 is installed in the mounting slot 301, the elastic force of the spring 304 acts on the ball bearing 305, keeping it in close contact with the top surface of the drug core 4. During the rolling of the drug core 4, the ball bearing 305 rolls along with it, and the elastic force of the spring 304 applies a downward pressure to the drug core 4, keeping it in close contact with the retainer 5. As the drug layer on the surface of the drug core 4 is gradually consumed, the diameter of the drug core 4 will decrease slightly. At this time, the spring 304 pushes the ball bearing 305 downward, automatically compensating for the gap and maintaining continuous pressure on the drug core 4.

[0036] This embodiment utilizes an elastic clamping structure composed of springs and ball bearings to eliminate the gap between the medication core and the mounting groove, preventing the core from wobbling during rolling and improving rolling stability. Simultaneously, this structure can adapt to minute changes in the core diameter, ensuring the core maintains appropriate contact pressure with the skin, resulting in more even and continuous medication application.

[0037] Example 4 Please see Figure 4The drug core 4 includes a non-drug support ball core 401, and a drug layer 402 of a certain thickness is attached to the outer circumferential surface of the non-drug support ball core 401.

[0038] Working principle: The non-drug-supported core 401 serves as the basic framework, providing support and shaping. The drug layer 402 is uniformly attached to the outer surface of the support core 401 through methods such as impregnation, spraying, or adhesion. During use, the drug layer 402 comes into direct contact with the skin, releasing the drug components during rolling. Once the drug layer 402 is consumed, the support core 401 can be disposed of as waste or recycled for manufacturing new drug cores.

[0039] This embodiment employs a structure that supports the separation of the drug core and the drug layer, simplifying the manufacturing process of the drug core and reducing production costs. The support core can be made of lightweight and inexpensive materials, with the drug only attached to the outer layer, thus avoiding waste of drug materials.

[0040] Example 5 This embodiment expands upon the grip structure based on Embodiment 1. Please refer to... Figure 6 The grip 2 has a detachably connected columnar handle 203, with a handle 204 at the end of the handle 203 away from the grip 2. Specifically, the grip 2 has a threaded hole 201, and the end of the handle 203 away from the handle 204 has a screw 202, which is threaded into the threaded hole 201. The handle 203 is telescopic.

[0041] Working principle: When applying to hard-to-reach areas such as the back and legs, screw the screw 202 at one end of the handle 203 into the threaded hole 201 on the handle 2 to connect. The user holds the handle 204 to operate, and the extended handle 203 transmits force to the medicated core mounting plate 3, causing the medicated core 4 to roll and apply to the target area. The extension length of the handle 203 can be adjusted according to the required application distance. When the extension is not needed, the handle 203 can be unscrewed from the handle 2, and the handle 2 can be used alone for operation. When used with antipruritic herbal powder, it can achieve an antipruritic effect and can be applied to hard-to-reach areas such as the back.

[0042] This embodiment significantly expands the device's reach with its detachable, extended handle, allowing users to easily apply the product to areas difficult to reach with their hands, such as their back and legs, making it particularly suitable for the elderly or those with mobility issues. The extendable design further enhances the flexibility of length adjustment, accommodating different heights and usage scenarios. The threaded connection is secure and reliable, and it is easy to store and carry after disassembly.

[0043] Example 6 Based on Example 1, this embodiment further includes an ultraviolet sterilization device on the inner wall of the mounting groove 301.

[0044] The ultraviolet sterilization device can sterilize the core 4 inside the installation slot 301.
