Description

Technical Field

[0001] The utility model relates to the technical field of medicine, and more specifically to a disposable oral ulcer encapsulation film. Background Art

[0002] Oral mucositis refers to an inflammatory and ulcerative reaction of the oral mucosal epithelial tissue, manifested as oral mucosal erythema, ulcers and pain. Different studies have reported that the incidence of oral mucositis in chemotherapy patients is 20% to 80%, and the incidence of oral mucositis in head and neck radiotherapy patients is as high as 100%. Although there are currently a variety of drugs to treat oral mucositis, due to the secretion of saliva in the mouth and the swallowing action, the drugs applied or sprayed in the oral mucosa are quickly diluted and eliminated, making it difficult to maximize the efficacy and obtain the best treatment effect.

[0003] There are currently four types of drugs for the treatment of oral mucositis, specifically:

[0004] (1) Liquid agents: such as kinin peptide, which is administered in the form of spray, and iodine glycerol, which is administered in the form of topical application;

[0005] (2) Gels or creams: such as Jinfuning and compound chamomile lidocaine gel, which are administered by topical application;

[0006] (3) Powders: such as Smecta, oral ulcer powder, which are administered in the form of topical spray or application;

[0007] (4) Oral mucosal patches: oral ulcer patches and propolis oral films, which are administered in the form of local patches.

[0008] However, although there are many types of liquid, gel, cream, and powder drugs mentioned above, they can be selected and used according to the specific situation of oral mucositis and are highly targeted; the disadvantage is that it is difficult for the drugs to stay in the local area for a long time, which limits the efficacy of the drugs.

[0009] In addition, oral ulcer patch is a common patch for treating oral diseases, which has a certain effect on the treatment of ulcers. There are many kinds of drugs for treating oral ulcers, but each drug has certain indications and may not be suitable for all patients. Inappropriate treatment will aggravate the condition and make the body resistant and drug-resistant. Utility Model Content

[0040] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0041] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0042] The disposable oral ulcer sealing film 100 according to an embodiment of the present utility model is described in detail below with reference to the accompanying drawings.

[0043] like Figures 1 to 8 As shown, the disposable oral ulcer sealing film 100 according to the embodiment of the utility model includes a main body 1, and the main body 1 includes: a first adhesive layer 111, a permeable layer and a protective layer 114.

[0044] Specifically, one side of the first adhesive layer 111 is sticky and adheres to the inner wall of the oral cavity 200. The first adhesive layer 111 has a channel that penetrates along its thickness direction. The portion of the first adhesive layer 111 that is not provided with a through hole fixes the medicine applied to the wound of the inner wall of the oral cavity 200 to the inner wall of the oral cavity 200. The permeable layer is located on the other side of the first adhesive layer 111. At least a portion of the other side of the first adhesive layer 111 is sticky to connect with the inner side of the permeable layer. The medicine applied to the wound of the inner wall of the oral cavity 200 can enter the permeable layer and the space between the permeable layer and the first adhesive layer 111 through the channel. The permeable layer is a porous structure with pores. At least a portion of the protective layer 114 is adhered to the outside of the permeable layer. The protective layer 114 is used to prevent water outside the protective layer 114 from entering the permeable layer to dilute the medicine.

[0045] Among them, the first adhesion layer 111, the permeation layer and the protective layer 114 are all food-grade water-soluble film layers, and the required water-soluble time of the protective layer 114 is shorter than the efficacy time of the drug.

[0046] In other words, the disposable oral ulcer sealing film 100 according to the embodiment of the utility model is mainly composed of a main body 1 , wherein the main body 1 is mainly composed of a first adhesive layer 111 , a permeable layer and a protective layer 114 .

[0047] The inner side of the first adhesive layer 111 can be bonded to the inner wall 200 of the oral cavity, that is, the inner wall of the first adhesive layer 111 can be bonded to the inner wall 200 of the oral cavity. Since the first adhesive layer 111 has a plurality of through channels, the permeable layer is disposed on the outer side of the first adhesive layer 111, one end of the channel can be connected to the inner wall 200 of the oral cavity, and the other end of the channel can be connected to the permeable layer.

[0048] It can be seen that, on the one hand, the surface of the first adhesive layer 121 where no channel is set can limit the position of the drug, and the drug is sandwiched between the first adhesive layer 121 and the inner wall of the oral cavity 200 to achieve fixation of the drug; on the other hand, the drug pre-coated on the wound position of the inner wall of the oral cavity 200 can pass through the channel on the first adhesive layer 111 into the permeation layer and between the permeation layer and the first adhesive layer 111, and this part of the drug can be buffered in the permeation layer to achieve subsequent continuous and uninterrupted drug delivery, wherein the permeation layer can have a porous structure.

[0049] That is, the first adhesive layer 111 can be used as an inner layer, and the first adhesive layer 111 has adhesive force and permeability, and can play a role of sticking and fixing in the oral mucosa. Moreover, the drug can also penetrate into the permeable layer and be temporarily absorbed in the permeable layer. Moreover, the permeable layer has a certain absorption and permeability, and the drug cached in the permeable layer can penetrate into the oral cavity inner wall 200 through the first adhesive layer 111 and be gradually released through the permeable layer.

[0050] In addition, the protective layer 114 can be used to prevent the drug in the permeation layer from flowing to the outside, that is, the drug cannot continue to permeate from the permeation layer to the outside, so as to achieve unidirectional release of the drug. The protective layer 114 can also be used to prevent external water from passing through the protective layer 114, that is, to prevent water in the oral cavity from passing through the protective layer 114, that is, the protective layer 114 has the ability to isolate saliva from permeating inward, so as to maintain the integrity of the encapsulation film.

[0051] Moreover, the first adhesive layer 111, the permeation layer and the protective layer 114 are all water-soluble film layers. That is to say, the first adhesive layer 111, the permeation layer and the protective layer 114 can finally melt in the oral cavity. Moreover, the encapsulation film is made of food-grade materials, which can dissolve by itself and be digested and absorbed. For another example, these four layers of materials are all biological preparations, reaching food grade, which can be kept for 15 minutes, and can dissolve by itself and be digested and absorbed after 15 minutes. It can be understood that the required water-soluble time of the protective layer 114 is less than the efficacy time of the drug, which can avoid affecting the efficacy of the drug. For example, the high efficacy time of the drug is 10 minutes, and the melting time of the protective layer 114 is 15 minutes, which will not affect the high efficacy of the drug.

[0052] When in use, the patient can pre-apply the medicine to the oral ulcer wound position of the oral cavity inner wall 200, and then apply the disposable oral ulcer encapsulation film 100 to the oral ulcer position. The first adhesive layer 111 is bonded to the oral cavity inner wall 200, and the excess medicine pre-applied on the oral ulcer enters the permeation layer through the channel of the first adhesive layer 111 and is absorbed by the permeation layer. Subsequently, the medicine adsorbed by the permeation layer is slowly released through the channel to reach the oral cavity inner wall 200, thereby achieving sustained release of the medicine. The protective layer 114 can prevent water in the oral cavity from penetrating and prevent the medicine from being diluted too quickly. In other words, the permeation layer has the function of adsorbing and slowly releasing the medicine. Once oral mucositis occurs, the encapsulation film is used after local medication. Since the disposable oral ulcer encapsulation film 100 is a water-soluble material, it can be naturally dissolved in the oral cavity within 15 minutes, for example.

[0053] Therefore, the disposable oral ulcer sealing film 100 according to the embodiment of the utility model is mainly composed of a main body 1, wherein the main body 1 is combined with a first adhesive layer 111, a permeation layer and a protective layer 114, which can not only realize the unidirectional release of the drug, but also can be based on the specific conditions of the patient's oral mucosa. After the targeted drugs are given, the part is sealed with the disposable oral ulcer sealing film 100, thereby avoiding the drug from being diluted, dissolved and swallowed quickly to a certain extent, giving full play to the efficacy of the drug and achieving the best effect.

[0054] According to an embodiment of the utility model, the number of permeable layers is multiple layers and they are stacked and bonded in sequence, and each permeable layer can absorb drugs and release drugs to adjacent permeable layers. For example, the multiple permeable layers are divided into a first permeable layer 112 and a second permeable layer 113, and the first permeable layer 112 and the second permeable layer 113 can be stacked. Specifically, at least a portion of the second permeable layer 113 and at least a portion of the protective layer 114 can be sequentially arranged on the outside of the first permeable layer 112, and at least a portion of the second permeable layer 113 can be located between the first permeable layer 112 and the protective layer 114. For example, the first adhesive layer 111, the first permeable layer 112, the second permeable layer 113 and the protective layer 114 are stacked, and at this time, the first permeable layer 112 is sandwiched between the first adhesive layer 111 and the second permeable layer 113, and the second permeable layer 113 is sandwiched between the first permeable layer 112 and the protective layer 114. In this embodiment, by adopting a multi-layer stacked permeable layer, the drug administration and the controlled duration of the sustained release of the drug can be achieved.

[0055] In one embodiment of the present invention, the area of ​​the permeable layer close to the protective layer 114 is larger than the area of ​​the permeable layer far from the protective layer 114. For example, the area of ​​the second permeable layer 113 is larger than the area of ​​the first permeable layer 112, and the outer edge of the second permeable layer 113 exceeds the outer edge of the first permeable layer 112, which can expand the contact area with the drug of the first permeable layer 112, improve the containing capacity, and prolong the sustained release time.

[0056] In some specific embodiments of the present invention, the area of ​​the protective layer 114 is larger than the area of ​​the permeable layer and the first adhesive layer 111, and the outer edge of the protective layer 114 exceeds the outer edges of the permeable layer and the first adhesive layer 111. In this embodiment, the area of ​​the protective layer 114 is the largest, and the outer edge of the protective layer 114 can exceed the outer edges of other layers. When the whole is attached to the inner wall 200 of the oral cavity, when the fingers pinch the outer edge of the protective layer 114, the fingers will not touch the first adhesive layer 111, which can prevent the fingers from contaminating or affecting the viscosity of the first adhesive layer 111.

[0057] According to an embodiment of the present invention, at least a portion of the outer edge of the protective layer 114 is provided with a second adhesive layer 116, and the second adhesive layer 116 is located outside the first adhesive layer 111 and is bonded to the inner wall 200 of the oral cavity. In this embodiment, the protective layer 114 has the largest area, and the outer edge of the protective layer 114 can exceed the outer edges of other layers. When the whole is attached to the inner wall 200 of the oral cavity, not only the first adhesive layer 111 can be adhered to the inner wall 200 of the oral cavity, but also the outer edge of the protective layer 114 can be adhered to the inner wall 200 of the oral cavity through the second adhesive layer 116. The first adhesive layer 111 and the inner wall 200 of the oral cavity can be adhered first, and then the second adhesive layer 116 and the inner wall 200 of the oral cavity can be adhered; or the connection between the first adhesive layer 111 and the inner wall 200 of the oral cavity and the connection between the second adhesive layer 116 and the inner wall 200 of the oral cavity can be achieved simultaneously. For example, the second adhesive layer 116 is annular and is arranged around the outer periphery of the first adhesive layer 111. In this embodiment, the protective layer 114 is designed to have the largest area and can be adhered to the inner wall of the oral cavity 200 through the second adhesive layer 116, so that the bonding strength between the whole and the inner wall of the oral cavity 200 can be improved. In addition, the protective layer 114 can also cover the outer edge of the permeable layer to prevent water in the oral cavity from entering the permeable layer through the edge of the permeable layer.

[0058] According to one embodiment of the utility model, the outer edges of the protective layer 114 and the first adhesive layer 111 on a side close to each other are connected by an annular third adhesive layer 115, and a closed space is enclosed between the protective layer 114 and the first adhesive layer 111. The permeable layer is located in the closed space, which can improve the sealing effect on the drug and is not easily contaminated or infiltrated by water in the oral cavity.

[0059] In some specific embodiments of the present invention, the pore size of the channel is larger than the pore size of the pore, so that the excess drug can quickly enter the sustained-release layer and the permeation layer can slowly release the drug.

[0060] According to one embodiment of the utility model, the main body 1 includes a plurality of dosing units 11 along its extension direction, and adjacent dosing units 11 are connected by a connecting portion 12. Each dosing unit 11 includes a first adhesive layer 111, a permeation layer and a protective layer 114 which are stacked.

[0061] According to one embodiment of the utility model, the connecting portion 12 has a plurality of spaced-apart dividing holes 121 distributed along its own extension direction. That is to say, the shape and area of ​​the medication portion can be realized by cutting or tearing the connecting portion 12, and flexible medication can be achieved, which can be controlled according to the position and shape of the wound to avoid some positions where it is difficult to attach larger structures. In addition, when the medication portion includes a plurality of medication units 11, adjacent medication units 11 can be located at different three-dimensional positions through the flexible connecting portion 12, and finally the overall three-dimensionality is realized, overcoming the problems of difficulty in attachment or easy warping caused by the inner wall 200 of the oral cavity being a non-planar surface such as a curved surface.

[0062] In some specific embodiments of the utility model, the drugs between the permeable layer and the first adhesive layer 111 corresponding to two adjacent dosing units 11 are the same or different. For example, the dosing part includes two dosing units 11, a left dosing unit and a right dosing unit. Along the direction from top to bottom, the left dosing unit and the right dosing unit can respectively include a protective layer 114-a second permeable layer 113-a first permeable layer 112-a first adhesive layer 111. And the drug components corresponding to the permeable layer of the left dosing unit and the drug components corresponding to the permeable layer of the right dosing unit can be the same or different. In this embodiment, when the drugs in the permeable layers corresponding to two adjacent dosing units 11 are the same, it is convenient to control the coverage of the wound area. When the drugs are different, different amounts or types of drugs can be administered according to the degree of wound ulceration, thereby improving the flexibility of medication.

[0063] According to one embodiment of the utility model, the connecting portion 12 has a plurality of spaced-apart dividing holes 121 distributed along its own extension direction. For example, the long side of the connecting portion 12 extends in the left-right direction, and a plurality of spaced-apart dividing holes 121 are provided on the connecting portion 12, thereby improving the convenience of separating two adjacent dosing units 11.

[0064] In some specific embodiments of the present invention, a fourth adhesive layer 122 is provided on the connecting portion 12 at the same side as the first adhesive layer 111 to bond with the inner wall of the oral cavity 200, which can not only improve the overall connection firmness with the inner wall of the oral cavity 200, but also reduce the water in the oral cavity from entering the permeable layer through the edge of the permeable layer after segmentation. In addition, adjacent dosing units 11 are separated by the fourth adhesive layer 122 on the connecting portion 12. For example, two dosing units 11 are separated by the fourth adhesive layer 122 on the connecting portion 12, which can prevent the permeable layers of two adjacent dosing units 11 from interfering with each other.

[0065] In summary, the disposable oral ulcer sealing film 100 according to the embodiment of the utility model includes a main body 1, and the main body 1 includes: a first adhesive layer 111, a permeation layer and a protective layer 114. The disposable oral ulcer sealing film 100 of this embodiment can be locally sealed with the disposable oral ulcer sealing film 100 after administering targeted drugs according to the specific conditions of the patient's oral mucosa, thereby preventing the drugs from being quickly diluted, dissolved and swallowed, giving full play to the efficacy of the drugs and achieving the best effect.
