Description

Technical Field

[0001] This utility model relates to the field of auxiliary patch technology, and more specifically, to a medical patch with sustained-release function. Background Technology

[0002] In the medical field, traditional methods of applying medication to the wound site have drawbacks such as short duration of action, frequent administration, increased patient discomfort, and impeded wound healing. To facilitate medication delivery, medicated patches are now commonly used instead of traditional topical application. These patches contain the medication itself, which is delivered to the wound site for treatment once applied.

[0003] However, when using traditional medical patches for treatment, the medication on these patches comes into direct contact with the wound, which can lead to excessively rapid drug release, resulting in waste and potential adverse reactions. This hinders the achievement of slow drug release and effective treatment. Therefore, we propose a medical patch with sustained-release function. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This utility model provides a technical solution: a medical patch with sustained-release function, including a bottom waterproof patch 1. The bottom waterproof patch 1 is used for waterproof protection, ensuring the waterproof performance of the medical patch during use and effectively protecting the drug inside the patch from external moisture.

[0026] Specifically, a patch assembly 2 is provided at the center of the inner surface of the bottom waterproof patch 1. The patch assembly 2 includes a first outer heat-pressed frame 20 fixedly installed on the inner surface of the bottom waterproof patch 1. A drug storage patch 21 is integrally formed at the center of the first outer heat-pressed frame 20. The drug storage patch 21 has multiple storage holes 211 arranged in a matrix, which are used for drug storage. A second outer heat-pressed frame 22 is provided on the upper surface of the first outer heat-pressed frame 20. A sustained-release layer 23 is provided at the center of the second outer heat-pressed frame 22. The sustained-release layer 23 has multiple micropores 231 arranged in a matrix, which enable the slow release of the drug to achieve a sustained-release effect. A third outer heat-pressed frame 24 is provided on the upper surface of the second outer heat-pressed frame 22. A skin-friendly adhesive layer 241 is provided at the center of the third outer heat-pressed frame 24. The skin-friendly adhesive layer 241 enhances the adhesion and comfort of the patch to the skin.

[0027] In this embodiment, the drug storage patch 21 can be made of porous silicone material with a pore size of 50 nanometers, which is made into a sheet with a thickness of 1 mm. The antibiotic drug for treating wounds is dissolved in an appropriate solvent, and then the drug is fully filled into the pores of the porous silicone material by vacuum impregnation to prepare the drug storage patch 21. The skin-friendly adhesive layer 241 is made of skin-friendly and breathable polyurethane material, which is made into a sheet with a thickness of 0.3 mm. This can improve the comfort of the patch when it is applied to the skin, while allowing the drug to pass through and act on the wound.

[0028] In this embodiment, the sustained-release layer 23 and the second outer hot-pressed frame 22 are integrally formed, and the skin-friendly adhesive layer 241 and the third outer hot-pressed frame 24 are integrally formed, ensuring the integrity and structural stability of the patch. This allows the sustained-release layer 23 to release the drug evenly and stably, while the skin-friendly adhesive layer 241 can closely adhere to the skin, improving the comfort and fit of use.

[0029] Specifically, the bottom of the drug storage patch 21 is integrally formed with a central cotton pad 25, and the bottom end of the storage hole 211 extends to the upper surface of the central cotton pad 25, providing a good storage and support environment for the drug, while also facilitating the uniform distribution and release of the drug, improving the drug utilization rate and therapeutic effect; the bottom of the central cotton pad 25 is provided with a bottom base layer 26, which is fixedly installed on the upper surface of the bottom waterproof patch 1, further enhancing the structural stability of the patch, making the patch less prone to deformation or detachment during use, while the bottom base layer 26 can also play a role in isolating and protecting the drug.

[0030] Furthermore, an adhesive layer 10 is provided on the upper surface of the bottom waterproof patch 1, and the patch assembly 2 is located at the center of the adhesive layer 10, which realizes the firm adhesion between the patch and the skin, ensuring that the patch is not easy to fall off or shift during use, thus improving the reliability and safety of use.

[0031] In addition, a release film 11 is provided on the surface of the adhesive layer 10, and a central hole 12 is provided at the center of the release film 11. The patch assembly 2 passes through the central hole 12, which makes it convenient for the user to peel off the release film 11 and expose the patch assembly 2 before use, thus improving the ease of use.

[0032] It is worth noting that a cut-off portion 13 is provided on one side of the release film 11. The cut-off portion 13 is in a broken state, which allows the user to easily tear off the release film 11 from the cut-off portion 13, further improving the convenience and flexibility of use.

[0033] It is worth noting that there are end tear-off stickers 14 at the opposite corners on both sides of the release film 11. The lower projection of the end tear-off stickers 14 is located outside the lower projection of the bottom waterproof sticker 1, providing users with additional tearing points, making it easier for users to tear off the entire release film 11, further improving the convenience of use and user experience.

[0034] When using the medical patch with sustained-release function of this utility model, firstly, the user needs to find the cut-off part 13 or the end tear-off patch 14 provided on the release film 11, and easily peel off the release film 11 along the cut-off part 13 or the end tear-off patch 14.

[0035] Once the release film 11 is completely removed, the patch assembly 2 is exposed. At this time, the user can observe the patch assembly 2 located at the center of the adhesive layer 10. The user applies the patch assembly 2 to the skin area that needs treatment. Due to the presence of the adhesive layer 10, the patch can be firmly adhered to the skin and is not easy to fall off or shift. At the same time, the skin-friendly adhesive layer 241 adheres to the skin and can improve comfort.

[0036] After the patch is applied, the medication will be slowly released through the storage hole 211 in the medication storage patch 21 and the micropores 231 on the sustained-release layer 23, allowing the medication to continuously act on the wound site.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
