Description

Technical Field

[0001] This utility model relates to the field of repair patches, specifically to a repair patch for inhibiting scar hyperplasia. Background Technology

[0002] Scar hyperplasia inhibitor repair patches are medical products used to prevent and treat scar hyperplasia. They mainly reduce the excessive growth of scar tissue through physical and chemical actions, promote wound healing and skin repair, protect wounds from external stimuli, promote epithelial cell growth, and accelerate wound healing. They are suitable for surgical incisions, burns, trauma, and other wounds.

[0003] In existing technologies, most healing patches are directly applied to the surface of the injured body. When the efficacy of the patch is exhausted, it needs to be removed from the injured surface and replaced in time. This process may cause secondary damage or discomfort to the wound and affect the treatment effect. Utility Model Content

[0022] This section will describe in detail the specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0023] Example 1:

[0024] like Figures 1 to 4 As shown, this utility model provides a repair patch for inhibiting scar hyperplasia, including an adhesive layer 1 that adheres to the skin, characterized in that it further includes:

[0025] Drug compartment 2 is disposed on adhesive layer 1. Drug compartment 2 has a receiving space inside. An opening for replacing drugs is provided on one side wall of drug compartment 2.

[0026] Drug module 3 is located inside drug compartment 2. The shape and size of drug module 3 are adapted to the storage space inside drug compartment 2. Drug module 3 and drug compartment 2 are detachably connected.

[0027] When using it, first apply the repair patch to the skin. When the medicine in the medicine module 3 is used up, simply take out the old medicine module 3 from the opening of the medicine compartment 2 and replace it with a new module. There is no need to peel off the entire repair patch. In this way, it avoids the damage to the skin caused by frequent peeling and application, and can continuously provide the medicine to help inhibit scar hyperplasia. It is very convenient to use.

[0028] Example 2:

[0029] like Figures 1 to 4As shown, in conjunction with the technical solution of Embodiment 1, in this technical solution, a rectangular through hole is provided on the bottom surface of the drug compartment 2, and a notch is provided on the adhesive layer 1 that matches the rectangular through hole on the bottom surface of the drug compartment 2. The adhesive layer 1 is firmly connected to the bottom surface of the drug compartment 2. In use, the repair patch only needs to be applied to the skin, and the drug compartment 2 can make close contact with the skin through the through hole and the notch to ensure that the drug continues to work. At the same time, the stability of the adhesive layer 1 will not be affected when the drug module 3 is replaced, making it both convenient and reliable to use.

[0030] Furthermore, each of the two opposite sidewalls at the opening of the drug compartment 2 has a receiving space that penetrates the sidewall. The receiving spaces are arranged in the following order along the outer sidewall to the inner sidewall of the drug compartment 2 in the horizontal direction: a first receiving space 4, a second receiving space 5, and a third receiving space 6. A push post 7 is slidably installed in the first receiving space 4 and extends into the second receiving space 5. A first spring 8 is sleeved on the outside of the push post 7 in the second receiving space 5. A locking head 9 is slidably installed in the third receiving space 6 and is fixedly connected to the push post 7. When the drug module 3 needs to be replaced, simply pull the push post 7 outward. The first spring 8 will be compressed, and the locking head 9 will also move outward, thereby unlocking the drug module 3. After releasing the push post 7, the spring will return to its original state. When inserting a new drug module 3, the locking head 9 will be pushed into the groove on the drug module 3 by the elastic force of the first spring 8, and re-fix the new drug module 3. This design makes the replacement of the drug module 3 very simple. The locking and unlocking operations can be completed by simply pushing and pulling the push post 7. It is both convenient and reliable, ensuring the stability of the drug module 3 and the ease of replacement.

[0031] Furthermore, an abutment plate 10 is fixedly installed on the portion of the push post 7 located outside the drug compartment 2. The abutment plate 10 abuts against the outer wall of the drug compartment 2, and a pull ring 11 is fixedly installed on one side of the abutment plate 10. The abutment plate 10 fixedly installed on the portion of the push post 7 outside the drug compartment 2 is tightly attached to the outer wall of the drug compartment 2 to ensure that the push post 7 will not slide arbitrarily. A pull ring 11 is also installed on one side of the abutment plate 10 for easy pulling with a finger. When it is necessary to replace the drug module 3, simply pull the pull ring 11, and the abutment plate 10 will move the push post 7 together, thereby unlocking the drug module 3. After releasing the pull ring 11, the push post 7 will return to its original position under the action of the spring, and relock the new drug module 3.

[0032] Furthermore, the locking head 9 is arc-shaped, and arc-shaped grooves 12 are provided on both sides of the drug module 3 for the locking head 9 to be inserted. Several second springs 13 are fixedly installed on the inner wall of the drug module 3 where it abuts against the drug chamber 2. The locking head 9 is designed to be arc-shaped, and the drug module 3 also has matching arc-shaped grooves 12 on both sides. In this way, the drug module 3 can smoothly push the locking head 9 into the third receiving groove during installation. At the same time, multiple springs are also installed on the inner wall of the drug module 3 where it contacts the drug chamber 2. These springs can ensure that when the locking head 9 unlocks the drug module 3, the drug module 3 can be smoothly and quickly ejected from the drug chamber 2, which is convenient for quick replacement of the new drug module 3.

[0033] Furthermore, a fixing strap 14 is fixedly connected to one side wall of the drug compartment 2, and a locking strap 15 is fixedly connected to the opposite side wall of the drug compartment 2. The fixing strap 14 has several slots 16, and the locking strap 15 has several latches 17. The slots 16 on the fixing strap 14 and the latches 17 on the locking strap 15 are matched to secure the drug compartment 2. In use, simply wrap the fixing strap 14 and locking strap 15 around the area requiring fixation, adjust the length, and insert the latches 17 on the locking strap 15 into the slots 16 of the fixing strap 14 to firmly secure the drug compartment 2. The fit between the slots 16 and latches 17 allows for easy adjustment of the tightness of the fixing strap 14, making it convenient and comfortable to use, ensuring the stability and ease of use of the repair patch.

[0034] Furthermore, the drug compartment 2 is made of medical-grade silicone material. This material is soft, conforms to the skin, and is safe and harmless to the human body. Medical-grade silicone has excellent elasticity, adapting to the shape of the skin to ensure that the drug compartment 2 adheres tightly to the skin and will not easily shift or fall off. At the same time, the silicone material is breathable, reducing discomfort after prolonged skin contact.

[0035] The working principle of a repair patch for inhibiting scar hyperplasia described in this application is as follows:

[0036] When using, apply the repair patch to the skin. Once the medication in the drug module 3 has run out, simply pull the pull ring 11 to remove the locking head 9 from the groove on the drug module 3, thus unlocking the drug module 3. At this time, the drug module 3 will pop out from the opening on the side wall of the drug compartment 2 under the elastic force of the second spring 13, making it easy to quickly replace the drug module 3. Take out the old drug module 3 from the drug compartment 2 and insert the new drug module 3 into the opening on the side wall of the drug compartment 2 until the locking head 9 on the side wall of the drug compartment 2 is inserted back into the groove on the drug module 3 under the drive of the first spring 8, thus completing the replacement of the drug module 3.
