Abstract
Description
Technical Field
[0001] This utility model relates to a traditional Chinese medicine plastering device, specifically a novel Sanfu plaster. Background Technology
[0002] Pediatric Sanfu Patch is a traditional Chinese medicine external treatment method used during the hottest days of summer (Sanfu) to prevent and treat certain diseases by applying patches to acupoints. Because children's skin epidermis and stratum corneum are thinner than adults', it is easier for them to absorb the medicine. Therefore, pediatric Sanfu Patch has the advantages of good efficacy, short treatment course, and can be used and left immediately.
[0003] However, in clinical practice, pediatric Sanfu Patch treatments are prone to patch displacement and detachment. The current solution is to repeatedly reinforce the fixation with medical tape. This process is cumbersome, wastes a lot of medical tape, and significantly increases the time of nursing staff. Moreover, applying too much tape can also create new burdens for pediatric patients, leading to tape allergies, irritability, or affecting the treatment effect. Utility Model Content
[0004] The purpose of this utility model is to overcome the aforementioned technical difficulties and provide a new type of Sanfu patch.
[0005] To achieve the above objectives, the technical solution adopted is as follows: a novel Sanfu patch, comprising a patch body, wherein the patch body is circular, and multiple strip-shaped patches extend outward from the edge of the patch body, and the patches are provided with easy-tear devices.
[0006] Furthermore, the adhesive tape has three strips arranged symmetrically at the center.
[0007] Furthermore, the outer edge of the tape is arc-shaped.
[0008] Furthermore, the easy-tear device is a pull strip, one end of which is fixedly connected to the adhesive tape, and the other end is pre-cut with an easy-tear half-cut line.
[0009] Furthermore, the easy-tear device is a liquid reservoir containing an adhesive remover; the inner wall of the liquid reservoir overlapping with the adhesive tape is provided with a tear-resistant film.
[0010] The beneficial effects of adopting the above-mentioned solution are as follows: This new type of Sanfu patch, specifically designed for children, adds multiple outward-extending strips to the conventional application method, offering significant advantages such as enhanced fixation, ease of operation, reduced application area, and easy removal. It improves application efficiency, prevents displacement and detachment, reduces child discomfort, and promotes proper drug absorption, thus ensuring therapeutic efficacy.

[0014] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. The described embodiments are merely some, not all, of these embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0015] Example 1
[0016] like Figure 1 A novel Sanfu patch includes a patch body 2. The patch body 2 is circular, with a medicine 1 placed at its center. Multiple strip-shaped adhesive tapes 3 extend outward from the edge of the patch body 2, each tape 3 having an easy-tear device 4. The area of the patch body 2 covering the medicine 1 is designed to be waterproof and leak-proof to prevent leakage or rainwater from wetting the medicine. The outer ring of the patch body 2 and the adhesive tapes 3 are made of breathable adhesive tape to improve comfort. After application, each adhesive tape 3 can be torn off using the easy-tear device 4.
[0017] Preferably, the adhesive tape 3 is arranged in three symmetrical strips, which makes the design aesthetically pleasing, the materials simple, and the production cost low. The outer edge of the adhesive tape 3 is arc-shaped, making it less likely to be accidentally rolled up. The three outwardly extending adhesive tapes 3 are firmly fixed to prevent the adhesive body 2 from shifting or falling off.
[0018] Preferably, the easy-tear device 4 is a pull strip, one end of which is fixedly connected to the adhesive tape 3, and the other end has a pre-set easy-tear half-cut line. The pull strip and the adhesive tape 3 are integrated, and the easy-tear half-cut line can prevent accidental tearing. The half-cut line should be printed with a mark for easy observation, so that one end of the pull strip can be torn off from the half-cut line, and then the adhesive tape 3 connected to it can be slowly torn off by slowly lifting the pull strip with force.
[0019] Example 2
[0020] like Figure 2 Based on Example 1, the easy-tear device 4 is a liquid reservoir containing an adhesive release agent; the inner wall of the reservoir, overlapping with the adhesive tape 3, is provided with a tear-resistant film. The adhesive release agent is set at 1 / 3 of the reservoir volume, making it difficult to break due to accidental contact or impact. Only when a finger fully presses down on the reservoir and applies force will the adhesive release agent break through the inner wall of the adhesive tape 3, wetting the adhesive and making the tape 3 very easy to tear off. This design allows for the use of stronger adhesive, improving the resistance to displacement and detachment of the Sanfu patch.
[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
[0022] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
