Description

Technical Field

[0001] This utility model relates to the field of medicated patch technology, and in particular to a topical patch for rheumatic bone injuries. Background Technology

[0002] Plasters are a type of external application of traditional Chinese medicine, formerly known as thin plasters. They are made by boiling medicinal herbs in vegetable or animal oil to form a gelatinous substance, which is then applied to one side of cloth, paper, or leather and can be worn on the affected area for a relatively long time. They are mainly used to treat boils, carbuncles, and reduce swelling and pain. There are hundreds, even thousands, of different traditional Chinese medicine plasters for orthopedic treatment, each with its own characteristics and effects. As people pursue a higher quality of life, they are increasingly demanding greater comfort and effectiveness during treatment, leading to the continuous emergence of new and more comfortable medicated plasters.

[0003] Existing topical plasters for treating rheumatic bone injuries are applied by pressing the plaster onto a backing layer. The backing layer is a one-piece design that can adhere to the human body surface. However, due to repeated friction between clothing and the edges of the backing layer, the backing layer is prone to curling, which may expose the plaster, stain the clothing, and increase the risk of the plaster falling off.

[0004] Therefore, it is necessary to provide a topical patch for rheumatic bone injuries to solve the above-mentioned technical problems. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a topical patch for rheumatic bone injuries that can reduce the risk of ointment exposure during use.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A topical patch for rheumatic bone injuries includes: a backing layer and an ointment layer fixed to one side of the backing layer; the backing layer includes an ointment fixing part and a protective part, the protective part including a first protective ring and a second protective ring sequentially fitted outside the ointment fixing part; an adhesive layer is provided on one side of the backing layer.

[0008] Preferably, the backing material is a flexible breathable film and / or woven elastic fabric.

[0009] Preferably, the adhesive layer is made of biocompatible silicone.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0025] Example 1:

[0026] like Figure 1-3As shown, the external patch for rheumatic bone injuries provided by this utility model includes: a backing layer and an ointment layer 2 adhered and fixed to one side of the backing layer. The ointment layer 2 can use the composition and proportion disclosed in CN102000306B for treating rheumatic bone injuries. The backing layer includes an ointment fixing part 1 located in the center and a protective part. The protective part includes a first protective ring 3 and a second protective ring 4 sequentially sleeved outside the ointment fixing part 1. If necessary, more protective rings can be provided. In this embodiment, two protective rings will be used for description. 2. Fixed at the center of the ointment fixing part 1, the ointment fixing part 1, the first protective ring 3, and the second protective ring 4, the backing layer is made of flexible breathable film (e.g., PE, PET, PU) and / or woven elastic fabric, etc. After molding, the material is cut multiple times to form the ointment fixing part 1, the first protective ring 3, and the second protective ring 4. An adhesive layer 7 is provided on one side of the backing layer (including the ointment fixing part 1, the first protective ring 3, and the second protective ring 4). The adhesive layer 7 can be made of biocompatible silicone or other materials. When in use, the ointment layer 2 faces the affected area. The ointment is applied to the skin at the affected area. Through the adhesive layer 7, the ointment fixing part 1 (exposed portion), the first protective ring 3, and the second protective ring 4 adhere to the skin. The first protective ring 3 and the second protective ring 4 sequentially surround the outer side of the ointment fixing part 1. When clothing is worn, the clothing will first rub against the outermost second protective ring 4, causing the second protective ring 4 to curl. After the second protective ring 4 curls, it will block the outer side of the first protective ring 3, and the overall thickness of the curled second protective ring 4 increases, preventing the clothing from contacting the outer side of the first protective ring 3. Since the first protective ring 3 and the second protective ring 4 are not connected, the first protective ring 3 is less likely to curl, which delays the curling time of the edge of the first protective ring 3. Even if the second protective ring 4 falls off, it will not directly affect the adhesion and fixation of the first protective ring 3. Similarly, after the edge of the first protective ring 3 curls up, it can delay the curling time of the edge of the ointment fixing part 1, which can effectively reduce the risk of the ointment fixing part 1 curling up or even the ointment being exposed during use, thereby reducing the risk of the ointment fixing part 1 falling off.

[0027] By setting a backing layer including the ointment fixing part 1, the first protective ring 3 and the second protective ring 4, the first protective ring 3 and the second protective ring 4 on the outside of the ointment fixing part 1 form multiple protections for the ointment fixing part 1, which can effectively reduce the possibility of the edge of the ointment fixing part 1 curling due to friction with clothing, reduce the risk of ointment exposure, and reduce the risk of the ointment fixing part 1 falling off.

[0028] Example 2:

[0029] like Figure 2-3As shown, a breathable layer 5 is provided between the ointment fixing part 1 and the ointment layer 2. The breathable layer 5 is bonded to the ointment layer 2 by hot pressing. The top of the breathable layer 5 is connected and fixed to the ointment fixing part 1. The breathable layer 5 is made of natural fibers, such as cotton fibers, which have good breathability. The ointment can penetrate into the breathable layer 5, making the connection tighter and less likely to fall off. Through this structural design, the ointment layer 2 and the ointment fixing part 1 can be better and more tightly connected, while also improving breathability.

[0030] By providing a breathable layer 5 between the ointment fixing part 1 and the ointment layer 2, the breathability can be improved while the connection stability between the ointment fixing part 1 and the ointment layer 2 can be enhanced.

[0031] Example 3:

[0032] like Figure 1-3 As shown, an anti-adhesive layer 6 is provided at the bottom of the ointment layer 2. The anti-adhesive layer 6 can be made of PET release film. The edge of the PET release film extends outward beyond the edge of the second protective ring 4, that is, the PET release film covers the entire backing layer and extends beyond it. The PET release film is bonded to the adhesive layer 7, sealing the ointment layer 2 inside, so that the ointment layer 2 does not come into contact with the outside world when not in use. When in use, the anti-adhesive layer 6 extends beyond the edge of the second protective ring 4, making it easier to peel off and use.

[0033] By setting an anti-stick layer 6 at the bottom of the ointment layer 2, the ointment layer 2 can be isolated and protected, and it is easy to peel off.

[0034] Example 4:

[0035] like Figure 2-3 As shown, a peelable protective layer 8 is provided on top of the backing layer. The material of the protective layer 8 can be polyethylene / polypropylene film. The protective layer 8 can be fixed to the top of the entire backing layer by multi-point adhesion, and its edge extends beyond the edge of the second protective ring 4. Its main function is to support and protect the entire backing layer. In use, the protective layer 8 is used in conjunction with the anti-adhesive layer 6 to protect the backing layer and the ointment layer 2, thereby improving the protection of the patch. After the ointment layer 2 is adhered to the human body, the protective layer 8 can be peeled off from the backing layer.

[0036] By setting a protective layer 8 on top of the backing layer, the top of the backing layer can be supported and protected.

[0037] Example 5:

[0038] like Figure 3 As shown, multiple air holes 11 are evenly opened on the ointment fixing part 1 to further improve the air permeability of the ointment fixing part 1.

[0039] By opening a vent hole 11 on the ointment fixing part 1, the air permeability of the ointment fixing part 1 can be further improved.

[0040] Working principle: During use, the ointment layer 2 is adhered to the skin of the affected area. When clothing is worn, the clothing will first rub against the outer edge of the outermost second protective ring 4, causing the second protective ring 4 to curl. After the second protective ring 4 curls, it will block the outer side of the first protective ring 3, and the overall thickness of the curled second protective ring 4 will increase, preventing the clothing from contacting the outer side of the first protective ring 3. Since the first protective ring 3 and the second protective ring 4 are not connected, the first protective ring 3 is less likely to curl, thus delaying the curling time of the edge of the first protective ring 3. Even if the second protective ring 4 falls off, it will not directly affect the adhesion and fixation of the first protective ring 3. Similarly, after the edge of the first protective ring 3 curls, it can delay the curling time of the edge of the ointment fixing part 1, which can effectively reduce the risk of the ointment fixing part 1 curling or even the ointment being exposed during use, and reduce the risk of the ointment fixing part 1 falling off.
