Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a home care medication application device for patients with psoriasis. Background Technology

[0002] Psoriasis is a complex dermatological disease, easily diagnosed but difficult to treat, with a long course. Patients often require topical medications after discharge. Treatment can be combined with Western medicine, traditional Chinese medicine, or a combination of both. Topical treatment for psoriasis generally involves local administration. Commonly used topical medications include corticosteroids, antifungals, antibacterial drugs, antiviral drugs, and keratolytic agents, categorized into Western and traditional Chinese medicine. Transdermal absorption is the theoretical basis for topical drug therapy. Topical medications increase the local drug concentration on the lesion, while systemic absorption is reduced, resulting in high efficacy and fewer adverse reactions. Currently, when applying ointments or liquids, patients typically use their fingers to take out the ointment or pour out some liquid before applying it to the skin. However, this application process not only introduces bacteria to the affected area, causing skin infection, but also contaminates the medication, is unhygienic, and results in uneven application and poor treatment outcomes.

[0003] For example, Chinese patent publication number "CN211245151U" discloses a "Psoriasis Topical Application Device," whose main structure includes a bottle, a pressing dispensing part, a delivery tube, and a protective cover. The pressing dispensing part is located at the top opening of the bottle; the delivery tube is located inside the bottle, with one end connected to the pressing dispensing part; the protective cover is located at the top of the bottle, and the pressing dispensing part is located inside the protective cover; the pressing dispensing part is provided with an application section. This psoriasis topical application device, when pressed, delivers the medication from the bottle to the application section, which is then applied to the affected skin, achieving topical medication treatment. It saves time and effort, eliminating the inconvenience of manually removing the medication, effectively preventing bacterial contamination of the medication and infection of the skin lesions, ensuring cleanliness and hygiene. Furthermore, after application, the protective cover is closed on the top of the bottle to prevent dust and contamination, effectively protecting the quality of the medication inside the bottle.

[0004] However, there are still cases where pressing causes backflow in the delivery tube, causing the application part to flow back into the medicine bottle, which in turn leads to contamination of the medicine inside the bottle. Summary of the Invention

[0017] 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.

[0018] Please see Figure 1 and Figure 2 A home care medication application device for psoriasis patients is disclosed. The application plate 114 and cotton pad 115 are disposable items. Before operation, the iron plate 23 needs to be pulled so that it is attracted to the surface of the annular permanent magnet 111 and the spiral spring 26 is compressed. At the same time, a single dose of medication is applied to the surface of the cotton pad 115, thus completing the preparation work before application.

[0019] To achieve a stretchable application effect, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 and Figure 4 A rotary telescopic application mechanism 1 is required. Its structure includes a handheld shell 11 that can be manually controlled and has a hollow internal structure, an inner sliding block 17 placed inside the handheld shell 11 and capable of moving along the axial direction of the handheld shell 11, a cotton pad 115 that can move relative to the axial direction of the handheld shell 11 and apply the product to the patient, and an annular permanent magnet 111 embedded inside one end of the handheld shell 11. By rotating the knob cap 14 in a directional manner, due to the threaded connection, the rotation of the external threaded rod 16 will cause the inner sliding block 17 to move in a directional manner. The inner sliding block 17 will then drive the axial telescopic rod 110 to extend and retract, thereby causing the cotton pad 115 to move and change the length of the device during use. After adjustment, hold the handheld shell 11 and then align the cotton pad 115 with the affected skin to apply the product to the affected skin, thereby achieving a telescopic application effect.

[0020] For details regarding the specific structure of the rotary telescopic applicator 1, please refer to [link / reference]. Figure 3 and Figure 4 It also includes an inner sliding cavity 12 disposed inside the handheld housing 11. Rotatable central shafts 13 are mounted inside both ends of the handheld housing 11 via bearings. Two central shafts 13 are connected at opposite ends by a coupling 15 to rotatable external threaded rods 16. A knob cap 14 is fitted onto the other end of one central shaft 13. An inner sliding block 17 capable of axial movement is placed inside the inner sliding cavity 12. The center of the inner sliding block 17 has an internal threaded hole 18 that is threaded onto the body of the external threaded rod 16. One end of the handheld housing 11 has two through holes 19 connecting the external space and one end of the inner sliding cavity 12. A ring-shaped permanent magnet 111 is embedded in one end of the handheld housing 11. Two axial telescopic rods 110 passing through the through holes 19 are fixedly mounted on one end of the inner sliding block 17. One end of each axial telescopic rod 110 has an integrally formed limiting ring structure 112. One end of 112 is provided with an insertion head 113 integrally formed with it. Part of the structure of the cotton pad 115 is embedded in the interior of the front side of the coating plate 114. The back side of the coating plate 114 is provided with two insertion slots 116 integrally formed with it. The insertion head 113 can be inserted into the insertion slots 116. The thread structure includes an internal thread structure set on the inner wall of the internal thread hole 18 and an external thread structure set on the rod body of the external thread rod 16. The internal thread structure is adapted to the external thread structure. The structural diameter of the insertion head 113 is smaller than the structural diameter of the limiting ring structure 112, and the structural diameter of the limiting ring structure 112 is larger than the structural dimension of the cross-section of the axial telescopic rod 110. The structural shape of the cross-section of the first rod body through hole 19 matches the structural shape of the cross-section of the axial telescopic rod 110. Both are polygonal structures, and the structural dimension of the cross-section of the first rod body through hole 19 is adapted to the structural dimension of the cross-section of the axial telescopic rod 110.

[0021] To achieve contactless disassembly, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 5 and Figure 6 An energy storage impact mechanism 2 needs to be set up. Its structure includes an impact plate 21 that can move along the axial direction of the handheld shell 11, an iron sheet 23 that can be attracted to the end of the annular permanent magnet 111 and drive the impact plate 21 to move, and a spiral spring 26 that can generate a power driving effect on the impact plate 21. After the coating is completed, the iron sheet 23 is pushed. When the iron sheet 23 gets rid of the attraction of the annular permanent magnet 111, the elastic potential energy of the spiral spring 26 will cause the impact plate 21 to generate kinetic energy, thereby causing the impact plate 21 to move quickly. When the impact rod 24 hits the impact plate 21, the impact plate 21 can be instantly detached from the insertion head 113, thereby realizing a quick and non-contact disassembly function.

[0022] For details regarding the specific structure of the energy storage impact mechanism 2, please refer to [link / reference]. Figure 5 and Figure 6 It also includes a limiting post structure 22 integrally set on one end face of the impact plate 21. One end of the limiting post structure 22 is equipped with two iron pieces 23 that can be attracted to the surface of the annular permanent magnet 111. The other end face of the impact plate 21 is provided with an impact rod 24 integrally set with it. The two sides of the impact plate 21 are provided with second rod body through holes 25 that can be sleeved on the rod body of the axial telescopic rod 110. The axial telescopic rod 110 has a helical spring 26 sleeved on the outside of the rod body located between the impact plate 21 and the handheld shell 11. The length of the impact rod 24 is greater than the sum of the length of the limiting ring structure 112, the length of the insertion head 113 and the depth of the insertion groove 116. The cross-sectional shape of the second rod body through hole 25 matches the cross-sectional shape of the axial telescopic rod 110, both being polygonal structures, and the cross-sectional dimensions of the second rod body through hole 25 are adapted to the cross-sectional dimensions of the axial telescopic rod 110.

[0023] In use, the application plate 114 and cotton pad 115 are disposable items. Before operation, the iron plate 23 needs to be pulled to attract it to the surface of the annular permanent magnet 111, compressing the helical spring 26. Simultaneously, a single dose of medication is applied to the surface of the cotton pad 115. Rotating the knob cap 14 in a specific direction causes the inner sliding block 17 to move due to the threaded connection. The inner sliding block 17 then drives the axial telescopic rod 110 to extend or retract, thereby moving the cotton pad 115. 5. Move the device to change its length during use. After adjustment, hold the outer casing 11 and then place the cotton pad 115 on the affected skin to apply it to the affected skin, thereby achieving a telescopic application effect. After application, push the iron plate 23. When the iron plate 23 breaks free from the attraction of the annular permanent magnet 111, the elastic potential energy of the spiral spring 26 will cause the impact plate 21 to generate kinetic energy, thereby causing the impact plate 21 to move quickly. When the impact rod 24 hits the impact plate 21, the impact plate 21 can instantly detach from the insertion head 113.
