Description

Technical Field

[0001] The invention relates to the technical field of medical wound patches, and in particular to a medical wound patch for continuous drug delivery. Background Art

[0002] Wound patches are medical materials used to prevent wound infection. Existing wound patches are applied by sticking sterile cloth patches on the skin. However, existing wound patches have the following problems: first, the wound-adhering part is a patch soaked with medicine, and the drug delivery effect is poor. In addition, for example, the joint wrapping and sticking method forms a tightly sticky state after use, which is not easy to tear off. Summary of the invention

[0003] The object of the present invention is to provide a method to solve the above-mentioned problems.

[0004] To achieve the above object, the present invention provides the following technical solution: a medical wound patch for continuous drug delivery, comprising:

[0005] The adhesive part is used to be attached to the skin;

[0006] Adhesive parts, which are arranged on both sides of the adhesive part and are used to cover the adhesive layer;

[0007] A contact portion, located in the middle of the sticking portion;

[0008] A medicine patch is arranged on the contact portion.

[0009] Optimally, a weak portion is provided on the back side of the sticking portion, a height difference exists between the weak portion and the back side, and a tearable connecting portion is provided at the weak portion.

[0010] Optimally, the medicine patch comprises a sterile contact layer, a slow seepage layer is arranged on the top of the sterile contact layer, and an isolation layer is arranged on the top of the slow seepage layer.

[0011] Optimally, the isolation layer is connected to the contact portion, an embedded space is provided between the isolation layer and the contact portion, and a medicine capsule is provided in the embedded space.

[0012] Optimally, the medicine capsule comprises a silica gel bag, one side of which is provided with barbs, and the silica gel bag is filled with liquid antibacterial gel.

[0013] Technical effects and advantages of the present invention:

[0014] The sterile contact layer is used to absorb blood and water while at the same time it can reversely infiltrate the medicine to the surface of the wound. In addition, the slow infiltration layer can retain the liquid antibacterial gel and allow it to slowly infiltrate the surface of the skin. The isolation layer prevents the liquid antibacterial gel from seeping out of the patch. The setting of the medicine bag can limit the liquid antibacterial gel. When in use, the silicone bag can be squeezed so that the barbs pierce the other side of the silicone bag, so that the liquid antibacterial gel can seep out. This is convenient to use and there is no need to match the corresponding medicine for wiping. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 3 It is a cross-sectional view of the medicine capsule of the utility model. DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Reference Figures 1 to 3 , a wound patch for medical continuous drug delivery, comprising:

[0020] The adhesive part 1 is used to be attached to the skin. A weak part 5 is provided on the back of the adhesive part 1. There is a height difference between the weak part 5 and the back. A tearable connecting part 4 is provided at the weak part 5. The adhesive part 2 is provided on both sides of the adhesive part 1 to cover the adhesive layer. The contact part 3 is located in the middle of the adhesive part 1.

[0021] The setting of the patch 1 allows the two sides to be located on the two sides of the wound and fit the skin when it is adhered. The adhesive part 2 can be torn off before fitting to ensure that the contact part 3 is located on the surface of the wound. The setting of the weak part 5 allows the overall patch 1 to maintain its integrity while being convenient for subsequent tearing. After use, the tearable connecting part 4 can be torn off to make the exposed weak part 5 easy to remove. In addition, the tearable connecting part 4 is a reinforcing part, which firmly fixes the patch 1 on both sides and improves the overall stability.

[0022] The medicine patch 6 is arranged on the contact part 3, and the medicine patch 6 includes a sterile contact layer 61, a slow seepage layer 62 is arranged on the top of the sterile contact layer 61, an isolation layer 63 is arranged on the top of the slow seepage layer 62, the isolation layer 63 is connected to the contact part 3, an embedded space 64 is arranged between the isolation layer 63 and the contact part 3, a medicine capsule 65 is arranged in the embedded space 64, the medicine capsule 65 includes a silica gel bag 651, a barb 653 is arranged on one side of the silica gel bag 651, and the silica gel bag 651 is filled with liquid antibacterial gel 652.

[0023] The sterile contact layer 61 is used to absorb blood and can reversely infiltrate the medicine to the surface of the wound. In addition, the slow infiltration layer 62 can retain the liquid antibacterial gel 652 and make it slowly infiltrate the surface of the skin. The isolation layer 63 prevents the liquid antibacterial gel 652 from seeping out of the patch 1. The setting of the medicine bag 65 can limit the liquid antibacterial gel 652. When in use, the silicone bag 651 can be squeezed so that the barb 653 pierces the other side of the silicone bag 651, so that the liquid antibacterial gel 652 can seep out. This is convenient to use and there is no need to match the corresponding medicine for wiping.

[0024] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
