Description

Technical Field

[0001] This application belongs to the technical field of medical devices, and specifically relates to a drug delivery dental appliance. Background Art

[0002] Periodontal disease refers to diseases that occur in the periodontal tissues, including gingivitis that only affects the gingival tissues and periodontitis that affects the deeper periodontal tissues (periodontal ligament, alveolar bone, cementum). Currently, there are various classification methods for periodontal disease, but it is mainly divided into gingivitis, periodontitis, periodontal trauma, juvenile periodontitis, and periodontal atrophy, etc. The main clinical manifestations of periodontal disease are gingival inflammation, bleeding, periodontal pocket formation, alveolar bone resorption, reduction of alveolar bone height, tooth loosening, displacement, etc.

[0003] There are various causes of periodontal disease, such as the influence of the microbial community on the teeth and periodontal tissues on the tooth surface, and the damage to the gingival tissues during orthodontics, which is likely to cause the disease.

[0004] During the clinical treatment process, drugs such as minocycline hydrochloride ointment, iodine glycerin, and chlorhexidine acetate solution are used to treat periodontal disease. Due to the presence of saliva in the oral cavity, the ointment applied to the affected area is likely to fall off under the influence of factors such as the tongue and saliva, thus affecting the treatment effect of the drug; moreover, some drugs have a stimulating effect on the oral mucosa, which is likely to cause discomfort to the patient. The patient will lick the uncomfortable area with the tongue. During this process, the stirring of the tongue and the flow of saliva will accelerate the detachment of the drug, resulting in a reduction in the drug dose at the affected area and affecting the treatment effect of the drug on the disease. Summary of the Utility Model

[0005] In order to reduce the irritation of the drug to the non-affected oral area in the oral cavity and increase the time for the drug to adhere to the affected area, this application provides a drug delivery dental appliance.

[0006] A drug delivery dental appliance, which includes a dental appliance main body.

The diameter of the medicine sac inlet section is larger than that of the medicine outlet section, the diameter of the medicine sac inlet section is not less than the diameter of the medicine storage sac, and the diameter of the medicine outlet section is smaller than the diameter of the medicine storage sac. The medicine sac inlet section is provided with two connecting parts. After the medicine storage sac enters the installation hole through the medicine sac inlet section, the elastic band bypasses the medicine storage sac and is connected to the two connecting parts, and can apply a force to the medicine storage sac in the direction close to the medicine outlet section.

[0009] In an embodiment of the present application, the outer wall of the medicine storage sac is provided with an extrusion groove, and the elastic band passes through the extrusion groove and is connected to the two connecting parts.

[0010] In an embodiment of the present application, the medicine storage sac includes two relatively arranged rigid sac walls and a flexible sac wall arranged between the two rigid sac walls. One of the rigid sac walls is provided with a release hole, and the other rigid sac wall is provided with an extrusion groove. The installation hole is a stepped hole, and the shoulder at the connection of the medicine sac inlet section and the medicine outlet section restricts the rigid sac wall from approaching the alveolar socket along the medicine outlet section. The elastic band passes through the extrusion groove and applies a force to the rigid sac wall in the direction close to the alveolar socket along the installation hole.

[0011] In an embodiment of the present application, the medicine storage sac includes two relatively arranged rigid sac walls and a flexible sac wall arranged between the two rigid sac walls. One of the rigid sac walls is clamped with the installation hole, the elastic band is wound around the outer wall of the medicine storage sac, and the elastic band presses the flexible sac wall.

[0012] In an embodiment of the present application, the medicine storage sac is provided with an elastic surrounding plate, and the elastic surrounding plate encloses a medicine delivery channel. The medicine storage cavity communicates with the outside through the release hole and the medicine delivery channel.

[0035] For a clearer understanding of the technical features, objectives, and effects of this application, the specific implementation manners of this application are now described with reference to the accompanying drawings. In the drawings, the same reference numerals denote components having the same or similar structures but the same functions.

[0036] In this document, "schematic" means "serving as an example, instance, or illustration", and any illustration or implementation manner described as "schematic" in this document should not be construed as a more preferred or more advantageous technical solution.

[0037] To simplify the drawings, only the parts related to this application are schematically shown in each drawing, and they do not represent the actual structure of the product. Additionally, for the sake of simplicity and ease of understanding of the drawings, in some drawings, for components having the same structure or function, only one of them is schematically shown, or only one of them is labeled.

[0038] Please refer to Figures 1 to 9 to understand this application.

[0039] Refer to Figure 1 , Figure 2 , a drug - delivering dental appliance, which includes a dental - appliance main body 101. The dental - appliance main body 101 is provided with a labial side surface, a dental alveolus 107, and mounting holes 103 communicating with the dental alveolus 107. Along the extending direction of the labial side surface, the dental - appliance main body 101 is provided with a plurality of mounting holes 103; the drug - delivering dental appliance further includes a medicine - storage sac 201. Refer to Figure 1 , Figure 3 , Figure 4 , the medicine - storage sac 201 is provided with a medicine - storage cavity 202 capable of storing medicine and a release hole 203 communicating with the medicine - storage cavity 202. The medicine - storage cavity 202 communicates with the outside through the release hole 203; the medicine - storage sac 201 is detachably connected to the mounting hole 103. When the medicine - storage sac 201 is connected to one of the mounting holes 103, the release hole 203 communicates with the dental alveolus 107 through the mounting hole 103.

[0040] Refer to Figure 1 , Figures 5 to 8 , in an implementation manner of this application, the medicine - storage sac 201 is flexible; the drug - delivering dental appliance further includes an elastic band 301. The elastic band 301 can be made of elastic materials such as rubber. The elastic band 301 is connected to the outer wall of the medicine - storage sac 201 and can apply pressure to the outer wall of the medicine - storage sac 201. The mounting hole 103 includes an inlet section 104 communicating with the outside and a medicine - outlet section 105 communicating with the dental alveolus 107. The diameter of the inlet section 104 is larger than the diameter of the medicine - outlet section 105. Refer to Figure 2, the diameter of the medicine inlet section 104 is not less than that of the medicine storage sac 201. The medicine storage sac 201 can enter the installation hole 103 through the medicine inlet section 104. The diameter of the medicine outlet section 105 is smaller than that of the medicine storage sac 201. The medicine outlet section 105 limits the medicine storage sac 201 from passing through the installation hole 103 into the tooth groove 107 by its size; the medicine inlet section 104 is provided with two connecting parts 106. The two connecting parts 106 are two hooks which can hook the elastic band 301. After the medicine storage sac 201 enters the installation hole 103 through the medicine inlet section 104, the elastic band 301 bypasses the medicine storage sac 201 and is connected to the two connecting parts 106, and can undergo elastic deformation to apply a force to the medicine storage sac 201 in the direction close to the medicine outlet section 105. See Figure 8 , because the diameter of the medicine outlet section 105 is smaller than that of the medicine storage sac 201, the medicine storage sac 201 cannot pass through the medicine outlet section 105 into the tooth groove 107. At the same time, because the elastic band 301 applies a force to the medicine storage sac 201 in the direction close to the tooth groove 107 along the medicine outlet section 105, the elastic band 301 restricts the medicine storage sac 201 from detaching from the installation hole 103. The connection parts of the elastic band 301 with the medicine outlet section 105 and the medicine inlet section 104 squeeze the medicine storage sac 201. The medicine storage sac 201 is flexible. Under the combined action of the elastic band 301 and the installation hole 103, the medicine storage sac 201 deforms, so that the medicine storage cavity 202 deforms and its volume decreases. The medicine in the medicine storage cavity 202 leaves the medicine storage cavity 202 through the release hole 203. The release hole 203 is communicated with the tooth groove 107 through the installation hole 103. Thus, the medicine finally enters the tooth groove 107 through the release hole 203. Of course, the connecting part 106 can also be other structures, such as a ring, as long as it can fix the elastic band 301, which will not be elaborated here.

[0041] In the above process, the medicine moves in the release hole 203, the installation hole 103 and the tooth groove 107, and the tongue in the oral cavity cannot contact the medicine, thus avoiding the patient licking the medicine. At the same time, the way the medicine moves in the release hole 203, the installation hole 103 and the tooth groove 107 greatly reduces the amount of saliva in contact with the medicine, avoids the flushing of the medicine at the affected area by saliva, and improves the adhesion time of the medicine at the affected area. The medicine storage cavity 202 has a protective and isolating effect on the medicine. The medicine can continuously enter the tooth groove 107 through the release hole 203 and the installation hole 103 within a period of time, thus ensuring the therapeutic effect of the medicine on the affected area. The medicine storage cavity 202 can store powder, liquid and paste medicines, and the medicine can leave the medicine storage cavity 202 through the release hole 203. This application has high adaptability.

[0042] See Figure 3 , Figure 4, in an embodiment of the present application, an extrusion groove 206 is provided on the outer wall of the medicine storage sac 201. The elastic band 301 passes through the extrusion groove 206 and is connected to the two connecting parts 106. In the way that the elastic band 301 is connected to the two connecting parts 106 through the extrusion groove 206, the extrusion groove 206 can limit the elastic band 301 and prevent the elastic band 301 from moving on the outer wall of the medicine storage sac 201.

[0043] See Figure 3 、 Figure 4 , in an embodiment of the present application, the medicine storage sac 201 includes two relatively arranged rigid sac walls 204 and a flexible sac wall 205 provided between the two rigid sac walls 204. A release hole 203 is provided on one of the rigid sac walls 204, and an extrusion groove 206 is provided on the other rigid sac wall 204; the mounting hole 103 is a stepped hole. See Figure 2 , the shoulder of the hole at the connection between the medicine inlet section 104 and the medicine outlet section 105 restricts the rigid sac wall 204 from approaching the tooth groove 107 along the medicine outlet section 105. The elastic band 301 applies a force along the direction of approaching the tooth groove 107 along the mounting hole 103 to the rigid sac wall 204 through the extrusion groove 206. Thus, under the action of the elastic band 301 and the shoulder of the mounting hole 103, the flexible sac wall 205 is squeezed and deformed, and the medicine in the medicine storage cavity 202 is squeezed into the tooth groove 107. In the way of the cooperation between the rigid sac wall 204 and the flexible sac wall 205, the rigid sac wall 204 can squeeze the medicine in the medicine storage cavity 202 with a larger area, reducing the volume of the medicine storage cavity 202, and thus reducing the medicine residue in the medicine storage cavity 202.

[0044] Of course, the mounting hole 103 is not limited to a stepped hole and can also be a conical hole. Along the direction of approaching the tooth groove 107, the diameter of the mounting hole 103 gradually decreases, so that the diameter of the medicine outlet section 105 is smaller than the diameter of the medicine inlet section 104.

[0045] See Figure 3 、 Figure 9 , in an embodiment of the present application, the medicine storage sac 201 is provided with an elastic enclosure 207. The elastic enclosure 207 encloses a medicine delivery channel 208. The medicine storage cavity 202 communicates with the outside through the release hole 203 and the medicine delivery channel 208; when the medicine storage sac 201 is connected to the mounting hole 103, the medicine delivery channel 208 passes through the mounting hole 103 and enters the tooth groove 107. When the tooth 401 and the gum enter the tooth groove 107, the elastic enclosure 207 entering the tooth groove 107 undergoes elastic deformation, and the elastic enclosure 207 fits on the tooth 401 and the periodontal tissue. Thus, the outlet of the medicine delivery channel 208 is attached to the affected area, and the medicine in the medicine storage cavity 202 can reach the affected area through the release hole 203 and the medicine delivery channel 208, continuously providing medicine to the affected area.

[0046] Those skilled in the art to which this application pertains can understand that the setting manner of the elastic band 301 and the medicine storage sac 201 in this application is not limited to the manner in which the two connecting parts 106 of the elastic band 301 are connected to the two mounting holes 103. There can also be other ways. For example, in an embodiment of this application, the medicine storage sac 201 includes two relatively arranged rigid sac walls 204 and a flexible sac wall 205 disposed between the two rigid sac walls 204. One of the rigid sac walls 204 is snap-connected to the mounting hole 103. The elastic band 301 is wound around the outer wall of the medicine storage sac 201 (not shown in the accompanying drawings of the specification). The elastic band 301 presses the flexible sac wall 205. The elastic band 301 is wound around the medicine storage sac 201. After the medicine storage sac 201 is snap-connected to the mounting hole 103, the elastic force squeezes the medicine in the medicine storage cavity 202 through the two rigid sac walls 204 with a relatively large area. The flexible sac wall 205 deforms, so that the medicine enters the tooth groove 107 through the release hole 203 and the mounting hole 103 under the squeezing action. The release hole 203 can be provided on the rigid sac wall 204 or on the flexible sac wall 205. When the medicine storage sac 201 is snap-connected to the mounting hole 103, the release hole 203 can communicate with the tooth groove 107 through the mounting hole 103, so that the medicine can enter the tooth groove 107.

[0047] Those skilled in the art to which this application pertains can understand that there are various ways for the medicine storage sac 201 to be detachably connected to the mounting hole 103, not limited to the above-mentioned manner in which the elastic band 301 fixes the medicine storage sac 201 in the mounting hole 103 or the manner in which the rigid sac wall 204 of the medicine storage sac 201 is connected to the mounting hole 103 by snap connection. There are also other ways. For example, the mounting hole 103 is a round hole, and the inner wall of the mounting hole 103 is provided with threads. The rigid sac wall 204 of the medicine storage sac 201 is provided with threads for threaded connection with the mounting hole 103, so as to realize the detachable connection between the medicine storage sac 201 and the mounting hole 103. Of course, there are also other ways, which will not be elaborated here.

[0048] In an embodiment of this application, the medicine storage sac 201 is provided with an oral-soluble film (not shown in the accompanying drawings of the specification) for closing the release hole 203. Before the medicine storage sac 201 enters the oral cavity, the oral-soluble film closes the release hole 203 to prevent the medicine in the medicine storage cavity 202 from entering the outside through the release hole 203. When the medicine storage sac 201 enters the oral cavity, the oral-soluble film contacts the saliva in the oral cavity, so that the oral-soluble film dissolves and no longer closes the release hole 203. The medicine can pass through the release hole 203 and the mounting hole 103 to enter the tooth groove 107 for treating the teeth 401 and the periodontal tissue at a specific position.

[0049] Those skilled in the art to which this application pertains can understand that the number of the medicine storage sacs 201 in this application can also be multiple. Refer to Figure 1, the dental appliance main body 101 can be connected to two medicine storage sacs 201, and the multiple medicine storage sacs 201 are connected to the mounting holes 103 at multiple different positions to release medicaments to the affected parts in different regions.

[0050] In an embodiment of the present application, the dental appliance main body 101 is elastic so as to adapt to the dental arches of different patients, and when the present application is worn, it can protect the patient's teeth 401 and prevent the dental appliance main body 101 from damaging the teeth 401.

[0051] See Figure 5 , Figure 6 , in an embodiment of the present application, the occlusal surface of the dental appliance main body 101 is provided with working through holes 102 communicating with the alveolar sockets 107. Along the extending direction of the occlusal surface, a plurality of working through holes 102 are provided on the occlusal surface. By setting the plurality of working through holes 102, on the one hand, the weight of the dental appliance main body 101 is reduced, and on the other hand, the occlusal surface of the teeth 401 is exposed, and other medicaments can be applied to the occlusal surface of the teeth 401 through the working through holes 102.

[0052] It should be understood that although this specification is described according to various embodiments, not every embodiment only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard 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.

[0053] The series of detailed descriptions listed above are only specific descriptions of the feasible embodiments of the present application, and they are not used to limit the protection scope of the present application. Any equivalent implementation or change made without departing from the technical spirit of the present application, such as the combination, division, or repetition of features, shall be included in the protection scope of the present application.
