Description

Technical Field

[0001] This application relates to the technical field of oral care, and specifically to a dental patch fixing device with a slow-release gel layer. Background Art

[0002] With the continuous improvement of people's attention to oral health and aesthetics, tooth whitening, care and other related products and technologies have received extensive attention and rapid development. The increasing demand for oral care has prompted the emergence of many innovative products. As a convenient and efficient oral care product, dental patches have been widely used in multiple fields such as tooth whitening, tooth protection, and gum care, and have become an indispensable daily care tool in modern life.

[0003] Traditional dental patches usually consist of a gel layer containing whitening or care ingredients and a backing layer for fixing the gel layer. When in use, the dental patch is directly attached to the tooth surface, and the active ingredients in the gel layer come into contact with the teeth to achieve effects such as whitening and care. However, in actual applications, after the gel in the dental patch is directly attached to the tooth surface, it often releases a large amount in a short time, which is likely to cause irritation to the teeth. In addition, after the gel is quickly released, it is easily affected by factors such as saliva secretion and oral muscle movement, resulting in poor adhesion between the dental patch and the teeth, and thus seeping into other parts of the oral cavity, which not only causes waste, but also is difficult to continuously provide sufficient active ingredients for the teeth, affecting the treatment effect.

[0004] Therefore, this application provides a dental patch fixing device with a slow-release gel layer to solve the above problems. Summary of the Invention

[0005] This application provides a dental patch fixing device with a slow-release gel layer, aiming to solve the existing problems presented in the background art.

[0006] To achieve the above object, this application provides the following technical solution: A dental patch fixing device with a slow-release gel layer includes a U-shaped silica gel block, a U-shaped groove opened on the U-shaped silica gel block for tooth socketting, and a storage and release structure provided on the U-shaped silica gel block and communicating with the U-shaped groove for gel storage and release; The storage and release structure includes an elastic capsule fixedly arranged in the U-shaped silica gel block for filling with gel, an extrusion capsule fixedly arranged on the side of the U-shaped silica gel block away from the U-shaped groove and in contact with the elastic capsule for tooth biting and extrusion, and a slow-release channel arranged in the U-shaped silica gel block and communicating with the elastic capsule and the U-shaped groove for continuously releasing the gel in the elastic capsule into the U-shaped groove; The squeezing capsules and the sustained-release channels are both provided with a plurality of them; the gel is stored in the elastic capsules, and the gel is continuously released into the U-shaped groove by the sustained-release channels. When the teeth occlude and squeeze the plurality of squeezing capsules, the elastic capsules are squeezed, and the gel can be slowly and continuously released into the area where the U-shaped groove contacts the teeth. Compared with the one-time release of gel by the traditional tooth patch, this sustained-release design can ensure that the therapeutic ingredients continue to act on the teeth for a long time, give full play to their whitening, care and other effects, avoid poor treatment effects due to rapid loss of gel, and reduce stimulation. At the same time, the gel is released by squeezing the plurality of squeezing capsules by the teeth occluding. This design conforms to people's daily oral action habits and is simple and convenient to operate. The user does not need to perform complicated operation steps, and can release the gel by normal occlusion, thereby improving the convenience of use. The design of the plurality of squeezing capsules and the plurality of sustained-release channels enables the elastic capsules to be more comprehensively and evenly pressured when the teeth occlude, so that the gel can be more evenly released into the U-shaped groove through each sustained-release channel, ensuring that all parts of the teeth can be treated evenly, avoiding the situation of too much or too little local gel, and further improving the treatment effect and user experience.

[0007] Preferably, in order to ensure the stability of the connection between the device and the teeth, U-shaped elastic clips for providing elastic support are fixedly provided on the inner and outer sides of the U-shaped groove in the U-shaped silicone block corresponding to the teeth; the design of the U-shaped elastic clip allows the U-shaped elastic clip to fit the inner and outer sides of the teeth when the user fits the U-shaped groove on the U-shaped silicone block onto the teeth, and when the teeth are subjected to external force or perform actions such as chewing, the U-shaped elastic clip can undergo corresponding elastic deformation due to its own elastic properties, providing elastic support for the teeth, thereby enhancing the fit and stability between the device and the teeth, preventing the device from shifting or falling off on the teeth, ensuring that the gel can act on the teeth, and further improving the treatment effect.

[0008] Preferably, in order to further ensure the connection between the device and the teeth, a drainage hole for saliva discharge is opened on the U-shaped silicone block corresponding to the inner side of the U-shaped groove; the design of the drainage hole can effectively discharge the saliva accumulated in the U-shaped groove during use, on the one hand, reducing the dilution of the gel by saliva, ensuring the concentration of the effective ingredients of the gel, so that the gel can fully exert the whitening, care and other effects; on the other hand, preventing saliva from affecting the close contact between the device and the teeth, maintaining the stability of the device on the teeth, reducing the discomfort caused by the displacement of the device, further ensuring the connection between the device and the teeth, and improving the overall use experience and treatment effect.

[0009] Preferably, in order to achieve the release of the gel, the sustained-release channel includes a medicine inlet disposed in the U-shaped silica gel block and communicating with the elastic capsule, a slender port disposed in the U-shaped silica gel block and communicating with one end of the medicine inlet away from the elastic capsule, and a medicine outlet disposed in the U-shaped silica gel block with two ends respectively communicating with one end of the slender port away from the medicine inlet and the U-shaped groove; the medicine inlet, the slender port and the medicine outlet are designed such that when the teeth bite and squeeze the capsule to compress the elastic capsule, the gel in the elastic capsule enters the sustained-release channel from the medicine inlet, and finally the gel is released into the U-shaped groove through the medicine outlet to contact the teeth, thereby achieving the release of the gel.

[0010] Preferably, in order to achieve the slow release of the gel, the inner diameters of the medicine inlet and the medicine outlet are both larger than the inner diameter of the slender port; with such a design, when the elastic capsule is squeezed, the gel enters the sustained-release channel from the medicine inlet. Since the inner diameter of the medicine inlet is larger, the gel can flow smoothly, and then enters the slender port. The inner diameter of the slender port is smaller, which hinders the flow of the gel, slows down the flow rate of the gel, and finally the gel is slowly released into the U-shaped groove through the medicine outlet to contact the teeth, achieving the slow release of the gel, ensuring that the therapeutic components act on the teeth for a long time and fully exerting their efficacy.

[0011] Preferably, in order to further slow down the release rate of the gel, a threaded guide groove is fixedly provided on the inner wall of the slender port; with the design of the threaded guide groove, the gel will move along the track of the threaded guide groove during the flow in the slender port. The threaded guide groove can guide and restrict the gel, making the flow path of the gel more tortuous, thereby increasing the flow resistance of the gel in the slender port, further slowing down the release rate of the gel, and further facilitating the control of the release amount of the gel.

[0012] Preferably, in order to effectively prevent the gel from leaking when the device is not in use, a film for sealing is fixedly provided at one end of the medicine outlet close to the U-shaped groove; in the initial state, the film can play a sealing role to seal the gel in the sustained-release channel. When the teeth bite and squeeze the capsule to compress the elastic capsule, the gel impacts the film under the action of pressure. As the pressure continues to increase, the film ruptures, realizing the normal release of the gel, ensuring that the gel can act precisely on the teeth when needed, and improving the use effect and reliability of the dental patch fixing device.

[0013] Preferably, in order to further improve the ease of use and cleaning effect of the device, a cleaning friction piece for contacting the tooth surface is provided at the upper edge of the inner side of the U-shaped groove of the U-shaped silicone block; the design of the cleaning friction piece enables the device to pre-clean the tooth surface during installation, thereby ensuring sufficient contact between the gel and the teeth and improving the treatment effect, and to clean the residual gel in time when removing the device to avoid adverse effects of the residual gel on the teeth or the oral environment, while also making the user's mouth feel more refreshed after use, thereby improving the ease of use and cleaning effect of the tooth patch fixing device.

[0014] Preferably, in order to achieve teeth cleaning, the cleaning friction member includes a rubber pad fixedly arranged on the upper edge of the inner side of the U-shaped groove of the U-shaped silicone block corresponding to the rubber pad for rubbing against the tooth surface, and the rubber pad is in the shape of comb teeth; the design of the rubber pad in the shape of comb teeth and the comb tooth structure can increase the contact area and friction with the tooth surface, more effectively penetrate into the tooth gaps, remove stains, water stains and residual gel on the tooth surface and in the gaps, and have a better cleaning effect. The rubber pad is soft in texture and will not cause damage to the tooth surface when rubbing against the teeth, thereby ensuring safety of use and improving the user experience and cleaning effect of the tooth sticker fixing device.

[0015] The tooth patch fixing device with a slow-release gel layer stores gel by arranging an elastic capsule, and continuously releases the gel into the U-shaped groove by using a slow-release channel. When the teeth occlude and squeeze the multiple extrusion capsules, the elastic capsules are squeezed, and the gel can be slowly and continuously released to the area where the U-shaped groove and the teeth are in contact. Compared with the traditional tooth patch that releases gel at one time, this slow-release design can ensure that the treatment ingredients continue to act on the teeth for a long time, giving full play to its whitening, care and other effects, avoiding poor treatment effects due to rapid loss of gel, and reducing irritation. The tooth patch fixing device with a slow-release gel layer causes the gel to be released by squeezing a plurality of extrusion capsules through tooth occlusion. This design conforms to people's daily oral action habits and is simple and convenient to operate. Users do not need to perform complicated operation steps and can release the gel by simply biting normally, thereby improving the convenience of use. The tooth patch fixing device with a slow-release gel layer is designed with multiple extrusion capsules and multiple slow-release channels, so that when the teeth are bitten, pressure can be applied to the elastic capsule more comprehensively and evenly, so that the gel can be released more evenly into the U-shaped groove through each slow-release channel, ensuring that all parts of the teeth can receive a uniform treatment effect, avoiding the situation of too much or too little local gel, and further improving the treatment effect and user experience; The design of the cleaning friction part of the dental patch fixing device with a sustained-release gel layer enables the device to pre-clean the tooth surface during installation, ensuring sufficient contact between the gel and the teeth, improving the treatment effect. When removed, it can clean the residual gel in time, avoiding adverse effects on the teeth or oral environment caused by gel residue. At the same time, it also makes the user's mouth fresher after use, improving the convenience and cleaning effect of the dental patch fixing device. Description of the Drawings

[0018] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0019] Embodiment 1 This embodiment provides a dental patch fixing device with a sustained-release gel layer, as Figures 1 - 4As shown in the figure, the dental patch fixing device includes a U-shaped silica gel block 1, a U-shaped groove 2 opened on the U-shaped silica gel block 1 for tooth socketing, and a storage and release structure 3 provided on the U-shaped silica gel block 1 and communicating with the U-shaped groove 2 for gel storage and release; the storage and release structure 3 includes an elastic capsule 31 fixedly arranged in the U-shaped silica gel block 1 and filled with gel, an extrusion capsule 32 fixedly arranged on the side of the U-shaped silica gel block 1 away from the U-shaped groove 2 and in contact with the elastic capsule 31 for tooth biting and extrusion, and a slow-release channel 33 arranged in the U-shaped silica gel block 1 and communicating with the elastic capsule 31 and the U-shaped groove 2 for continuously releasing the gel in the elastic capsule 31 into the U-shaped groove 2; a plurality of extrusion capsules 32 and slow-release channels 33 are provided.

[0020] During use, the user first inserts the teeth into the U-shaped groove 2 on the U-shaped silica gel block 1, and then squeezes a plurality of extrusion capsules 32 fixedly arranged on the side of the U-shaped silica gel block 1 away from the U-shaped groove 2 by biting the upper and lower teeth. After being squeezed, the plurality of extrusion capsules 32 will directly transfer the pressure to the elastic capsule 31 fixedly arranged in the U-shaped silica gel block 1 and filled with gel and in contact with them. Immediately afterwards, the elastic capsule 31 deforms under the action of the pressure, and the gel inside it flows out from the plurality of slow-release channels 33 communicating with the elastic capsule 31. Through the restriction of the slow-release channels 33, the gel can be continuously and slowly released into the U-shaped groove 2, and then the released gel can be in full contact with the teeth socketed in the U-shaped groove 2 to exert the whitening, nursing and other effects of the gel and achieve the therapeutic effect on the teeth.

[0021] Specifically, U-shaped elastic clips 11 for providing elastic support are fixedly arranged on the inner and outer sides of the U-shaped groove 2 in the U-shaped silica gel block 1. When the user inserts the teeth into the U-shaped groove 2 on the U-shaped silica gel block 1, the U-shaped elastic clips 11 fixedly arranged on the inner and outer sides of the U-shaped groove 2 in the U-shaped silica gel block 1 start to play a role. At the moment when the teeth are inserted, the U-shaped elastic clips 11 will produce elastic deformation due to the extrusion of the teeth. At this time, the U-shaped elastic clips 11 will tightly wrap the teeth, providing stable and uniform elastic support for the teeth to ensure the close fit between the device and the teeth and prevent the device from loosening or shifting during use. At the same time, when the teeth bite and squeeze the extrusion capsule 32 and the gel in the elastic capsule 31 is released into the U-shaped groove 2 through the slow-release channel 33 and contacts the teeth, the elastic support of the U-shaped elastic clip 11 can also ensure the stable structure of the U-shaped groove 2 and make the gel act on the tooth surface.

[0022] Among them, in order to further ensure the connection and use of the device and the teeth, a liquid discharge hole 12 for saliva discharge is provided on the U-shaped silicone block 1 corresponding to the inner side of the U-shaped groove 2; the design of the liquid discharge hole 12 can effectively discharge the saliva accumulated in the U-shaped groove 2 during use. On the one hand, it reduces the dilution of the gel by saliva, ensures the concentration of the active ingredients of the gel, enables the gel to fully exert its whitening, care and other effects. On the other hand, it prevents saliva from affecting the close contact between the device and the teeth, maintains the stability of the device on the teeth, reduces the discomfort caused by the displacement of the device, further ensures the connection and use effect of the device and the teeth, and improves the overall use experience and treatment effect.

[0023] Furthermore, the slow-release channel 33 includes a medicine inlet 331 provided in the U-shaped silicone block 1 and communicating with the elastic capsule 31, a slender port 332 provided in the U-shaped silicone block 1 and communicating with one end of the medicine inlet 331 away from the elastic capsule 31, and a medicine outlet 333 provided in the U-shaped silicone block 1 with both ends communicating with one end of the slender port 332 away from the medicine inlet 331 and the U-shaped groove 2 respectively. The inner diameters of the medicine inlet 331 and the medicine outlet 333 are both larger than the inner diameter of the slender port 332; When the user squeezes the extrusion capsule 32 by biting the upper and lower teeth, after the elastic capsule 31 is squeezed, the gel filled inside the elastic capsule 31, under the action of pressure, first enters the slow-release channel 33 through the medicine inlet 331 provided in the U-shaped silicone block 1 and communicating with the elastic capsule 31. Since the inner diameter of the medicine inlet 331 is relatively large, the gel can flow in smoothly. Then the gel enters the slender port 332 communicating with one end of the medicine inlet 331 away from the elastic capsule 31. Also, since the inner diameter of the slender port 332 is smaller than that of the medicine inlet 331 and the medicine outlet 333, the flow rate of the gel slows down when passing through the slender port 332, playing a role in buffering and current limiting to slow down the release rate of the gel. Finally, the gel will flow into the medicine outlet 333 through the slender port 332, and then flow out through the medicine outlet 333 and be released into the U-shaped groove 2, making full contact with the teeth sleeved in the U-shaped groove 2.

[0024] Still further, a threaded guide groove 334 is fixedly provided on the inner wall of the slender port 332; when the teeth bite and squeeze the extrusion capsule 32 and the elastic capsule 31 is pressed, the gel enters the slow-release channel 33 from the medicine inlet 331 and then flows into the slender port 332. Since the threaded guide groove 334 is fixedly provided on the inner wall of the slender port 332, when the gel flows in the slender port 332, it will move along the spiral track of the threaded guide groove 334, thereby increasing the flow resistance of the gel in the slender port 332, making the flow rate of the gel further slow down, and further controlling the speed at which the gel is released from the medicine outlet 333 into the U-shaped groove 2, ensuring that the gel can fully and evenly contact the teeth sleeved in the U-shaped groove 2, and greatly improving the treatment effect of the tooth patch fixing device.

[0025] In addition, in order to effectively prevent gel leakage when the device is not in use, a sealing film 335 is fixedly arranged at one end of the medicine outlet 333 close to the U-shaped groove 2. In the initial state, the film 335 can play a sealing role to enclose the gel in the slow-release channel 33. When the teeth bite and squeeze the extrusion capsule 32 to compress the elastic capsule 31, the gel impacts the film 335 under the action of pressure. As the pressure continues to increase, the film 335 ruptures, so that the normal release of the gel can be realized, ensuring that the gel can accurately act on the teeth when needed, and improving the use effect and reliability of the tooth patch fixing device.

[0026] It should be noted that the film 335 is made of polyvinyl alcohol material. The polyvinyl alcohol film has a certain solubility in water, but can form a dense film structure in the dry state, effectively preventing gel leakage. When the gel impacts the film 335 under the action of pressure, due to the presence of a certain amount of moisture or solvent components in the gel, it will accelerate the dissolution or softening of the polyvinyl alcohol film in the local area, reduce the strength of the film, and make it easier to rupture when reaching a certain pressure.

[0027] Embodiment 2 Different from Embodiment 1, as Figures 5 - 6 shown, in order to further improve the use convenience and cleaning effect of the device, a cleaning friction member 4 for contacting the tooth surface is arranged at the upper edge inside the U-shaped groove 2 corresponding to the U-shaped silica gel block 1. The design of the cleaning friction member 4 enables the device to pre-clean the tooth surface during installation, ensuring full contact between the gel and the teeth, improving the treatment effect, and being able to clean the residual gel in time when removed, avoiding the adverse effects of gel residue on the teeth or oral environment, and also making the user's mouth more refreshing after use.

[0028] Furthermore, the cleaning friction member 4 includes a rubber pad 41 fixedly arranged at the upper edge inside the U-shaped groove 2 corresponding to the U-shaped silica gel block 1 for rubbing against the tooth surface, and the rubber pad 41 is in a comb shape. When the teeth are inserted into the U-shaped groove 2 of the U-shaped silica gel block 1 and the fixing device is pushed, or during the process of removing the device, the rubber pad 41 fixedly arranged at the upper edge inside the U-shaped groove 2 corresponding to the U-shaped silica gel block 1 will come into contact with the tooth surface. Since the rubber pad 41 is in a comb shape, the comb structure can penetrate into the gaps between the teeth and the uneven places on the tooth surface when the rubber pad 41 rubs against the tooth surface, so as to more effectively scrape off the stains, water stains and residual gel on the tooth surface, achieve more thorough cleaning, ensure the tooth surface is clean, enable the gel to better contact the teeth and play a role, and improve the overall use effect of the tooth patch fixing device.

[0029] As described above, it is only the preferred specific implementation manner of the present application. However, the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and its concept of the present application, making equivalent replacements or changes, shall be covered by the protection scope of the present application.
