Description

Technical Field

[0001] The invention belongs to the technical field of dental trays, and in particular relates to a double-layer dental tray. Background Art

[0002] The fluoridation foam anti-caries operation often requires the cooperation of a dental tray. The fluoridation foam anti-caries operation process is: first, gently squeeze the fluoridation foam into the dental tray, and then put the dental tray with fluoridation foam into the child's mouth and let it bite gently. After three minutes, spit out the dental tray, and spit out the fluoridation foam in the mouth completely into the food bag, thus completing the fluoridation foam anti-caries operation.

[0003] In the above-mentioned fluoridated foam anti-caries operation, there are the following problems: the height of the dental tray is generally consistent with the height of the gums and the dental tray space is large. During the operation, the fluoridated foam needs to be squeezed into the dental tray, and only part of the fluoridated foam in the dental tray that is in direct contact with the teeth plays a role in preventing dental caries, while most of the fluoridated foam that is not in contact with the teeth cannot be fully utilized, resulting in unnecessary waste. Although dental trays are currently provided in large, medium and small sizes for children of different ages, there is still a lot of space after the teeth are placed in the dental tray, and this space can only be filled with fluoridated foam to allow the teeth to fully contact the fluoridated foam. In addition, fluoridated foam is very expensive. If the use of fluoridated foam can be reduced, its medical cost can be reduced. Summary of the invention

[0004] In view of this, the present invention provides a double-layered dental tray, which can effectively solve the problem of waste of fluoride foam in the prior art.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a double-layered dental tray, comprising a dental tray body, wherein the dental tray body comprises an arc-shaped outer groove body similar to the shape of the tooth arrangement, wherein the outer groove body is provided with an arc-shaped inner groove body similar to the shape of the tooth arrangement, and the bottom of the inner groove body is connected to the bottom of the inner wall of the outer groove body.

[0006] Furthermore, the outer peripheral wall of the inner tank body is arranged to fit the inner wall of the outer tank body.

[0007] Furthermore, the outer peripheral wall of the inner tank body is fixed on the inner wall of the outer tank body.

[0008] Furthermore, the inner groove height of the inner groove body is 0.5-0.8 cm, and the inner groove height of the outer groove body is greater than the overall height of the inner groove body.

[0009] Furthermore, the tray body also includes an inner cover, which is arranged above the inner groove body and the lower end surface of the inner cover is tightly arranged with the upper end wall of the inner groove body, the upper end surface of the inner cover and the upper end surface of the outer groove body are in the same plane, and the peripheral wall of the inner cover is in contact with the inner wall of the outer groove body.

[0010] Furthermore, the tray body also includes a sealing film, which covers the inner cover, and the end edge of the sealing film is thermally composited or bonded to the upper end edge of the outer groove body.

[0011] Furthermore, the lower end surface of the sealing film is connected to the upper end surface of the inner cover.

[0012] Furthermore, the tray body also includes an end handle, and the end handle is connected to the raised portion of the outer groove body.

[0013] Furthermore, the inner tank contains fluoride foam, whitening agent or other tooth protection ointment.

[0014] Furthermore, the two ends of the tray body are symmetrically connected to an identical tray body through a connecting belt.

[0015] Furthermore, a notch indentation is provided in the middle of the connecting belt.

[0016] Furthermore, one of the symmetrically arranged end handles is provided with a socket into which the other end handle can be inserted.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: in the present invention, fluoride foam, tooth guard or other tooth guard agents can be squeezed into the inner tank body, and then the mouthpiece body can be placed in the upper or lower teeth. In the present invention, since the inner tank space of the inner tank body is much smaller than the inner tank space of the outer tank body, the usage of fluoride foam, tooth guard or other tooth guard agents can be saved. In the present invention, the outer tank body plays a role of stable support. Through the arrangement of the inner tank body in the present invention, the usage of fluoride foam can be effectively reduced. In addition, the arrangement of the inner cover and the sealing film makes it easy to contain the fluoride foam in the inner tank body. When applying fluoride, the sealing film and the inner cover can be directly opened and placed directly in the oral cavity. The operation is simple, the usage of fluoride foam can be reduced, and the teeth and the fluoride foam can be fully fitted. BRIEF DESCRIPTION OF THE DRAWINGS

Thus, features defined as "first", "second", and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0027] like Figure 1 As shown, a double-layered dental tray includes a dental tray body, wherein the dental tray body includes an arc-shaped outer slot body 1 similar to the shape of the teeth arrangement, wherein an arc-shaped inner slot body 2 similar to the shape of the teeth arrangement is arranged inside the outer slot body 1, and the bottom of the inner slot body 2 is connected to the bottom of the inner wall of the outer slot body 1.

[0028] In the above technical solution, the fluorinated foam 8, tooth guard or other tooth guard can be squeezed into the inner tank body, and then the mouthpiece body is placed in the upper and lower teeth. In this embodiment, since the inner tank space of the inner tank body is much smaller than the inner tank space of the outer tank body, the amount of fluorinated foam, tooth guard or other tooth guard can be saved. In this embodiment, the outer tank body plays a role of stable support. In this technical solution, if the outer tank body is not provided or only the outer tank body is reduced in size without the inner tank body, the problem of fluorinated foam waste in the present invention cannot be solved for the following reasons: when the size becomes smaller, the stability of the mouthpiece will deteriorate, which is not conducive to use.

[0029] As a preferred embodiment of the above technical solution, the outer peripheral wall of the inner tank body 2 is arranged in close contact with the inner wall of the outer tank body 1. The outer peripheral wall of the inner tank body is in close contact with the inner wall of the outer tank body, which facilitates teeth to bite into the inner tank body and avoids teeth from biting into the space between the inner tank body and the outer tank body.

[0030] As a preferred embodiment of the above technical solution, the outer peripheral wall of the inner tank body 2 is fixed to the inner wall of the outer tank body 1. The outer peripheral wall of the inner tank body can be fixed to the inner wall of the outer tank body by thermal bonding or bonding, or the inner tank body and the outer tank body are integrally formed.

[0031] As a preferred embodiment of the above technical solution, the inner groove height of the inner groove body 2 is 0.5-0.8cm, and the inner groove height of the outer groove body 1 is greater than the inner groove body height. In this embodiment, different sizes of dental trays can be made according to the size of common teeth. The inner groove height of the inner groove body is slightly smaller than the height of the teeth, and the inner groove height of the outer groove body is greater than the overall height of the inner groove body. Generally, the upper end face of the outer groove body is arranged at the gums. In addition, the groove space of the inner groove body matches the arrangement of the teeth, and the inner groove height of the inner groove body is slightly smaller than the height of the teeth. This setting is because when the teeth bite into the inner groove body, the surrounding walls of the inner groove body will move closer to the teeth, and the fluoride foam in the inner groove body will overflow upward along the teeth, so that the teeth are coated with fluoride foam, and the fluoride foam can be prevented from adhering to the gums, thereby reducing the amount of fluoride foam used. The height of the inner groove body is generally set to be 0.5-1mm lower than the height of the teeth.

[0032] As a preferred embodiment of the above technical solution, Figure 2 As shown, the dental tray body also includes an inner cover 3, which is arranged above the inner tank body 2 and the lower end surface of the inner cover 3 is tightly arranged with the upper end wall of the inner tank body 2, the upper end surface of the inner cover 3 is in the same plane with the upper end surface of the outer tank body 1, and the peripheral wall of the inner cover 3 is in contact with the inner wall of the outer tank body 1. In this technical solution, the fluorinated foam is squeezed into the inner tank body, and then the upper end of the inner tank body is covered by the inner cover. Since the lower end surface of the inner cover is tightly arranged with the upper end wall of the inner tank body, the peripheral wall of the inner cover is in contact with the inner wall of the outer tank body, and the upper end surface of the inner cover is in the same plane with the upper end surface of the outer tank body, the fluorinated foam in the inner tank body can be sealed in the inner tank body to prevent the fluorinated foam from flowing out.

[0033] As a preferred embodiment of the above technical solution, Figure 3 and Figure 4 As shown, the dental tray body also includes a sealing film 4, which covers the inner cover 3, and the end edge of the sealing film 4 is thermally compounded or bonded to the upper end edge of the outer tank body 1. The setting of the sealing film 4 can keep the fluorinated foam in the inner cover and the inner tank body in a closed state to avoid the influence of the external environment on the fluorinated foam. When in use, the sealing film is torn off, the inner cover is taken out, and then the dental tray is directly placed in the oral cavity to bite the teeth, which is convenient to use. In addition, the sealing film can be made of PET film or paper film. In addition, a convex edge 9 is provided at the end edge of the sealing film, which is convenient for opening the sealing film by hand.

[0034] As a preferred embodiment of the above technical solution, the lower end surface of the sealing film 4 is connected to the upper end surface of the inner cover 3. The lower end surface of the sealing film and the upper end surface of the inner cover are connected together by thermal bonding or adhesive bonding. When in use, after the sealing film is opened, the inner cover is opened together with the sealing film, which is convenient for use.

[0035] As a preferred embodiment of the above technical solution, the dental tray body further comprises an end handle 5, which is connected to the raised portion of the outer tank body 1, so as to facilitate holding the dental tray. Figure 1-Figure 3 shown.

[0036] As a preferred embodiment of the above technical solution, fluoride foam, whitening agent or other tooth care ointment is contained in the inner tank 2. The inner tank can contain fluoride foam, tooth moss, whitening agent or other tooth care ointment, which is not limited to the use of fluoride foam and has a wide range of applications.

[0037] As a preferred embodiment of the above technical solution, the dental tray further comprises a connecting belt 6, and the two ends of the dental tray body are symmetrically connected to an identical dental tray body through the connecting belt 6. Here, the connecting belt may be in the shape of a long strip or an arc-shaped belt, and a notch indentation is provided in the middle of the connecting belt, so that two symmetrically arranged dental tray bodies can be separated from the notch indentation, so that fluoride can be applied only to the maxillary or mandibular teeth.

[0038] As a preferred embodiment of the above technical solution, one of the symmetrically arranged end handles 5 is provided with an insertion hole 7 for inserting the other end handle. The dental tray is folded in the opposite direction along the middle of the connecting band, and the end handle at one end is inserted into the insertion hole of the end handle at the other end, and then placed in the oral cavity, so that the upper and lower teeth are respectively placed in the inner grooves of the two folded dental tray bodies.
