Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a medicated patch structure. Background Technology

[0002] There are many problems that trouble users when using traditional medicated patches. First, when tearing off the release paper of ordinary medicated patches, due to the lack of effective positioning and auxiliary devices, users often find it difficult to apply precise force, and the release paper is often torn incompletely. This causes part of the adhesive side of the patch to be exposed prematurely, which not only affects the adhesion of the patch, but also makes it easy for foreign objects to come into contact with the patch before it is used, thus reducing its efficacy.

[0003] A search revealed Chinese Patent Publication No. CN209172976U, which discloses a novel medicated patch structure. This medicated patch includes a fixing patch and a drug carrier adhered to the fixing patch. The fixing patch has a surrounding sheet, a cotton yarn layer, and multiple spaced adhesive strips adhered to the cotton yarn layer. Release paper is laid on the adhesive strips. Non-woven fabric is also placed between the drug carrier and the fixing patch. A plastic protective film covers the outside of the drug carrier. When using this medicated patch, the release paper and protective film need to be peeled off. The fixing patch supports the drug carrier and is applied to the skin. The adhesive strips on the cotton yarn layer of the patch adhere to the skin. The gaps between the adhesive strips allow for ventilation, enabling the drug carrier to communicate with the outside environment and facilitating the volatilization of the drug within the drug carrier. Furthermore, the adhesive strips increase the breathability between the patch and the skin, allowing the skin at the patch location to breathe effectively.

[0004] Regarding the aforementioned technologies, the inventors discovered the following drawbacks: When the device is applied to specific parts of the human body, it lacks effective auxiliary positioning methods and relies solely on manual operation by the user. Due to the complex shapes of human body parts, especially precise treatment areas such as joints and acupoints, the medicated patch is prone to misalignment during application. Once the patch is misaligned, the medication cannot accurately target the area, significantly affecting the intended therapeutic effect. Utility Model Content

[0005] To address the problems mentioned in the background section, this application provides a medicated patch structure.

[0006] The present application provides a medicated patch structure, which adopts the following technical solution: a medicated patch structure, including a medicated patch base fabric, wherein an auxiliary positioning component is provided on one side of the medicated patch base fabric;

[0007] An auxiliary positioning component includes a medical cotton pad, a medicated dressing pad, an adhesive ring, a release paper, a release liner, and an extension tape. The medical cotton pad is adhered to one side of the medicated dressing base fabric, the release paper is adhered to the same side of the medicated dressing base fabric, an adhesive ring is fixedly connected to one side of the release paper, a medicated dressing pad is fixedly fitted inside the adhesive ring, a release liner is movably connected to one side of the adhesive ring, and an extension tape is fixedly connected to the bottom of the release liner.

[0008] The above solution achieves precise positioning and convenient application of the medicated patch, ensuring close contact between the patch and the skin, improving user comfort and drug release efficiency.

[0009] Optionally, the auxiliary positioning component further includes a positioning plate and a positioning groove. The positioning plate is fixedly connected to the surface of the patch base fabric near the release paper. The outline of the positioning plate is the same as the outline of the patch base fabric. The positioning plate has a positioning groove on the side near the extension tear-off point. The positioning groove is used to assist the extension tear-off point in tearing the release paper.

[0010] The above solution further optimizes the ease of peeling and pasting operations through the design of the positioning plate and positioning groove, especially in low-light environments, thus improving the user experience.

[0011] Optionally, the adhesive ring and the release paper together form a semi-closed cavity, and the depth of the semi-closed cavity is the same as the height of the medicated pad. The medicated pad is made of medical sponge and is filled with medicated liquid.

[0012] The above solution effectively prevents the evaporation or spillage of the medication, ensuring the long-lasting and stable efficacy of the medicated pad, while the medical sponge material enhances skin comfort.

[0013] Optionally, the positioning plate is made of silicone, and the side of the positioning plate away from the base fabric of the patch has a positioning groove and two circular grooves. The circular grooves are used to assist the user in extending the patch application by tactile positioning in dim lighting conditions.

[0014] The above solution enhances tactile perception by using a silicone positioning plate and a circular groove, making it easier for users to quickly find the extension sticker in low light conditions and improving ease of use.

[0015] Optionally, the area of ​​the release paper surface that overlaps with the medicated pad is set as a hydrophobic surface, and the outer ring of the hydrophobic surface is coated with an antibacterial coating.

[0016] The above-mentioned design, with its hydrophobic surface and antibacterial coating, effectively prevents the penetration of the medicine and the growth of bacteria, ensuring the hygiene of the patch and the stability of its efficacy.

[0017] Optionally, the depth of the semi-enclosed cavity is 2-5 mm, and the difference between the thickness of the medicated pad and the depth of the semi-enclosed cavity is less than or equal to 0.3 mm.

[0018] By precisely controlling the depth of the semi-enclosed cavity and the thickness of the medicated pad, the medicated liquid is evenly distributed and does not easily overflow, thus improving the effectiveness and safety of the medicated patch.

[0019] In summary, this application includes the following beneficial technical effects:

[0020] 1. This utility model, by incorporating components such as an adhesive ring, release paper, and a medicated dressing, utilizes the adhesive ring and release paper to form a semi-closed cavity. This interrelationship allows the medicated dressing to be fixed within the semi-closed cavity, effectively storing and protecting the medicinal liquid. Thus, this device achieves the effect of stably preserving the selected medicinal liquid through the protection of the semi-closed cavity, preventing its volatilization and contamination, and ensuring the stable efficacy of the medicated dressing.

[0021] 2. This utility model, by setting up a positioning plate, a positioning groove, and an extension tear-off patch, utilizes the interplay between the positioning groove on the positioning plate and the extension tear-off patch to allow the extension tear-off patch to be embedded in the positioning groove for convenient tearing of the release paper. Thus, this device, with the assistance of the positioning groove and the extension tear-off patch, enables quick and precise tearing of the release paper, facilitating the use of the patch and improving the user experience.

[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0028] This application discloses a medicated patch structure.

[0029] Please see Figure 1 A medicated patch structure includes a medicated patch base fabric 1, and an auxiliary positioning component 2 is provided on one side of the medicated patch base fabric 1;

[0030] Please see Figures 2 to 4 The auxiliary positioning component 2 includes a medical cotton pad 201, a medicated dressing pad 202, an adhesive ring 203, a release paper 204, a release paper 207, and an extension tear-off 208. The medical cotton pad 201 is pasted on one side of the medicated dressing base 1, and the release paper 204 is pasted on the same side of the medicated dressing base 1. An adhesive ring 203 is fixedly connected to one side of the release paper 204, and the medicated dressing pad 202 is fixedly sleeved inside the adhesive ring 203. The release paper 207 is movably connected to one side of the adhesive ring 203, and the extension tear-off 208 is fixedly connected to the bottom of the release paper 207.

[0031] The auxiliary positioning component 2 also includes a positioning plate 205 and a positioning groove 206. The positioning plate 205 is fixedly connected to the side surface of the patch base fabric 1 near the release paper 204. The outline of the positioning plate 205 is the same as the outline of the patch base fabric 1. The positioning plate 205 has a positioning groove 206 on the side near the extension tear 208. The positioning groove 206 is used to assist the extension tear 208 in tearing the release paper 207.

[0032] The adhesive ring 203 and the release paper 204 together form a semi-closed cavity, and the depth of the semi-closed cavity is the same as the height of the medicated pad 202. The medicated pad 202 is made of medical sponge and is filled with medicine.

[0033] The positioning plate 205 is made of silicone, and the side of the positioning plate 205 away from the base cloth 1 is provided with a positioning groove 206 and two circular grooves. The circular grooves are used to help the user to position and extend the peeling 208 by touch in a dimly lit environment.

[0034] The area on the side of the release paper 207 that overlaps with the medicated pad 202 is set as a hydrophobic surface, and the outer ring of the hydrophobic surface is coated with an antibacterial coating.

[0035] The depth of the semi-enclosed cavity ranges from 2 to 5 mm, and the difference between the thickness of the medicated pad 202 and the depth of the semi-enclosed cavity is less than or equal to 0.3 mm.

[0036] Further explanation is needed: the positioning plate 205 in the auxiliary positioning component 2 is closely connected to the base fabric 1 of the patch, and its outline is consistent with the base fabric 1 of the patch, playing an important positioning auxiliary role. The positioning groove 206 opened on the positioning plate 205 has a clever cooperation relationship with the extension tear strip 208. During the use of the patch, the extension tear strip 208 can be embedded in the positioning groove 206. This design gives the user a precise point of force when tearing the release paper 207. In this way, it can effectively avoid the release paper 207 being torn incompletely due to improper operation, or touching the adhesive surface of the adhesive ring 203 during the tearing process, ensuring the integrity of the patch before use, providing convenience for subsequent smooth patch application, and greatly improving the accuracy and convenience of the user when operating the patch.

[0037] In addition, the positioning plate 205 is made of silicone, which not only has good flexibility and can fit well with the skin, reducing skin irritation, but also has two circular grooves on the side of the surface away from the base fabric 1, in addition to the positioning groove 206. In dim lighting conditions, users can quickly locate the extension tear-off 208 by touching the circular grooves. This design fully considers different usage scenarios, so that the use of the patch is not limited by lighting conditions, further optimizing the user experience and ensuring that users can easily and accurately complete the preparation of the patch in any environment, improving the versatility and reliability of the patch.

[0038] The implementation principle of a medicated patch structure in this application embodiment is as follows:

[0039] First, when the patch is not in use, the positioning plate 205 is firmly connected to the patch base fabric 1, and its outline is consistent with the patch base fabric 1, playing a basic role in overall positioning and support. At the same time, the positioning groove 206 on the positioning plate 205 has not yet engaged with the extension tear 208, and the release paper 207 tightly covers one side of the adhesive ring 203, protecting the adhesive surface of the adhesive ring 203 and ensuring that the patch will not stick together during storage and transportation.

[0040] Secondly, when the user is about to use the patch, they will notice the positioning groove 206 on the positioning plate 205. At this time, the user will precisely embed the extension tear strip 208 into the positioning groove 206. This operation makes the extension tear strip 208 and the positioning plate 205 form a stable connection, providing a reliable point of force for tearing the release paper 207 later.

[0041] Next, the user, using the leverage point formed by the extension tear strip 208 embedded in the positioning groove 206, begins to slowly and steadily tear off the release paper 207. Due to the precise positioning of the extension tear strip 208 by the positioning groove 206, the user can apply force precisely during the operation, effectively avoiding incomplete tearing of the release paper 207 due to uneven force or improper operation, or touching the adhesive surface of the adhesive ring 203, thus ensuring the integrity of the patch in the process of tearing off the release paper 207.

[0042] Next, in dimly lit environments, the two circular grooves on the positioning plate 205 come into play. Users can quickly locate the position of the extension tear strip 208 by touching the circular grooves. This design allows users to accurately insert the extension tear strip 208 into the positioning groove 206 and tear off the release paper 207 even in poor lighting conditions, greatly improving the environmental adaptability of the patch.

[0043] Finally, after successfully tearing off the release paper 207, the adhesive side of the adhesive ring 203 is exposed. The user can then accurately attach the patch to the desired area. The silicone material of the positioning plate 205, due to its good flexibility, can adhere well to the skin, reducing skin irritation and ensuring that the patch can stably exert its medicinal effect after being attached, thus completing the entire process of using the patch.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
