Abstract
Description
Technical Field
[0001] This utility model relates to the field of dental medical device technology, and in particular to a dental cleaning auxiliary mouth opening device with an anti-aspiration device. Background Technology
[0002] When using manual teeth cleaning, current dental cleaning operations mainly rely on traditional metal or plastic mouth openers. The patient's mouth is forcibly kept open by mechanical clamping, and saliva is removed by an independent suction device. This suction device requires continuous operation by medical staff. The defects of the above operation method are: (1) Mouth opening maintenance problem: Most mouth openers are fixed at an angle that cannot be adjusted. Long-term mouth opening leads to temporomandibular joint fatigue. The rigid structure compresses the soft tissue of the oral cavity, causing discomfort. The lack of anti-slip design makes it easy for the device to shift. (2) Liquid management problem: Teeth cleaning is performed first, followed by rinsing. During the rinsing process, saliva, blood and rinsing fluid (which contains irritating drug components) mix and are easily accidentally entered into the pharynx, causing choking. The existing suction device needs to be manually adjusted, affecting the continuity of treatment. The low efficiency of liquid collection leads to frequent interruptions of operation. (3) Coordination problem: Most existing devices are designed separately, and they will interfere with each other's operating space when used at the same time. Utility Model Content
[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a dental cleaning auxiliary mouth opening device with an anti-aspiration device to solve the technical problems mentioned in the background art.
[0004] To solve the technical problem, this utility model adopts the following technical solution:
[0005] A dental cleaning mouth-opening device with an anti-aspiration mechanism includes a mouth opener, which comprises a left mouth-opening component and a right mouth-opening component. Each of the left and right mouth-opening components includes an upper mouth-opening element and a lower mouth-opening element, wherein the opening angle of the upper and lower mouth-opening elements is controlled by a damping hinge. The device also includes an anti-aspiration membrane, which is disposed between the left and right mouth-opening components, at the upper end of the tongue, and at the front of the throat.
[0006] Specifically, the damping hinge includes an upper hinge arm, a lower hinge arm, and a hinge shaft assembly. The upper hinge arm extends from the inner side of the upper opening member, and the lower hinge arm extends from the inner side of the lower opening member. The upper and lower hinge arms are hinged together by the hinge shaft assembly, which includes a hand-tightening shaft, a pivot nut, and a damping rubber ring.
[0007] Specifically, the anti-absorption membrane includes a mounting part and a liquid receiving part. The mounting part is in the shape of an annular rubber ring and is located on the outside of the anti-absorption membrane. The liquid receiving part is located on the inside of the mounting part and is connected to the mounting part. A liquid receiving bag for catching liquid is formed on the inside of the liquid receiving part.
[0008] Specifically, the mounting part has hanging holes on both sides, and the upper and lower opening parts have hooks on the inner sides corresponding to the hanging holes. The anti-aspiration film is installed by hanging it on the hooks through the hanging holes.
[0009] Specifically, the upper opening member has an upper biting groove at its upper end, and the lower opening member has a lower biting groove at its lower end.
[0010] Specifically, both the upper and lower bite grooves have anti-slip textures on their surfaces.
[0011] Specifically, both the upper hinge arm and the lower hinge arm are arc-shaped.
[0012] Specifically, both the left and right mouth opening components are made of medical-grade silicone composite transparent material and coated with a nano-silver antibacterial layer.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This utility model's teeth cleaning assist mouth opening device consists of two mouth opening components (left and right). Both components are configured as an upper and lower mouth opening member, with their opening angles controllable by damping hinges. An anti-aspiration membrane is placed between the two components to prevent aspiration. This membrane, hanging between the components, holds the tongue and throat, preventing medication from entering the throat during teeth cleaning. Furthermore, the upper end of the upper mouth opening member and the lower end of the lower mouth opening member are provided with occlusal grooves (upper and lower occlusal grooves), corresponding to the occlusion of the upper and lower molars respectively. Anti-slip textures are provided on the groove surfaces to reduce the foreign body sensation during biting and to increase the likelihood of the mouth opening components slipping during teeth cleaning. The overall structure is simple and easy to use. Attached Figure Description

Detailed Implementation
[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0024] refer to Figures 1 to 7 :
[0025] This utility model discloses a dental cleaning mouth-opening device with an anti-aspiration mechanism. It aims to provide a mouth-opening aid that is adjustable in opening angle, has an anti-aspiration structure, and provides minimal foreign body sensation and anti-slip properties during biting. Specifically, this dental cleaning mouth-opening aid includes a mouth opener 100, which comprises a left mouth-opening component 1 and a right mouth-opening component 2. (See reference...) Figure 4 Taking the drawing of the right mouth opening component 2 as an example, both the left mouth opening component 1 and the right mouth opening component 2 include an upper mouth opening member 11 and a lower mouth opening member 12. The opening angle of the upper mouth opening member 11 and the lower mouth opening member 12 is controlled by the damping hinge member 3. It also includes an anti-absorption membrane 4. The anti-absorption membrane 4 is set between the left mouth opening component 1 and the right mouth opening component 2, at the upper end of the tongue and the front end of the throat. With this setting, the opening angle of the upper mouth opening member 11 and the lower mouth opening member 12 can be controlled by the damping hinge member 3 to assist in opening the mouth and facilitate teeth cleaning. When rinsing is required after teeth cleaning, the anti-absorption membrane 4 is installed. Most of the rinsing medicine will enter the anti-absorption membrane 4, and then the medicine will be sucked out from the anti-absorption membrane 4 by the special suction device for teeth cleaning.
[0026] Specifically, the damping hinge 3 includes an upper hinge arm 31, a lower hinge arm 32, and a hinge shaft assembly 33. The upper hinge arm 31 extends from the inner side of the upper opening member 11, and the lower hinge arm 32 extends from the inner side of the lower opening member 12. The upper hinge arm 31 and the lower hinge arm 32 are hinged together by the hinge shaft assembly 33. The hinge shaft assembly 33 includes a hand-tightening shaft 331, a pivot nut 332, and a damping rubber ring 333. Specifically, both the upper hinge arm 31 and the lower hinge arm 32 contain a hinge joint with a hinge hole. The hand-tightening shaft 331 passes through two hinge holes on one side and connects to the pivot nut 332 on the other side. The damping rubber ring 333 is disposed between the two hinge joints, between the hand-tightening shaft 331 and one of the hinge joints, and between the pivot nut 332 and the other hinge joint. In both hinge joints, damping rubber rings 333 are provided at the hinge joint connection points, the hinge joint connection points with the hand-tightening shaft 331, and the hinge joint connection points with the pivot nut 332. When the hand-tightening shaft 331 is loosened, there is a lack of damping friction between the damping rubber rings 333 and their respective connecting parts, and the upper mouth opening member 11 and the lower mouth opening member 12 can rotate. At this time, the corresponding opening angle can be manually adjusted. After the predetermined angle is adjusted, the hand-tightening shaft 331 is tightened. At this time, the damping friction between the damping rubber rings 333 and their respective connecting parts increases, and the upper mouth opening member 11 and the lower mouth opening member 12 can no longer be adjusted. Therefore, the left mouth opening component 1 or the right mouth opening component 2 with the adjusted angle can be placed into the oral cavity for mouth opening assistance. It should be noted that the mouth opening angle here can be manually adjusted to the predetermined angle before being placed into the designated jaw.
[0027] In a subsequent improved embodiment, the damping hinge 3 also includes a torsion spring. One output end of the torsion spring abuts against the upper hinge arm 31, and the other output end abuts against the lower hinge arm 32. The main body of the torsion spring is passed through the screw-tightening shaft 331. In this scheme, the screw-tightening shaft 331 and the pivot nut 332 are responsible for tightening and loosening. When tightened, the upper hinge arm 31 and the lower hinge arm 32 are fixed. The main tension part that supports the anti-biting force comes from the torsion spring. When the original torsion spring is missing, it is necessary to rely entirely on the damping force of the screw-tightening shaft 331, the pivot nut 332, and the damping rubber ring 333 to counteract the biting force. Here, adding the torsion spring greatly reduces the anti-biting force of the above combination.
[0028] Specifically, the anti-aspiration membrane 4 includes a mounting part 41 and a liquid receiving part 42. The mounting part 41 is an annular rubber ring located on the outside of the anti-aspiration membrane 4. The liquid receiving part 42 is located inside the mounting part 41 and connected to it. A liquid receiving bag 421 for receiving liquid medication is formed on the inner side of the liquid receiving part 42. Preferably, the mounting part 41 is an elliptical rubber ring with a diameter larger than the diameter of a person's open mouth. This allows the edge of the mounting part 41 to extend towards the oral membrane with its larger diameter when it is hung between the left mouth opening component 1 and the right mouth opening component 2 to receive liquid medication, thereby maximizing the avoidance of aspiration. To prevent the medication from leaking onto the tongue or throat and causing irritation, the receiving part 42 is preferably a receiving bag 421. This receiving bag 421 has the characteristic of being smaller at the top and larger at the bottom, so that the medication will not easily flow out after it flows in. The depth of the receiving bag 421 is generally suitable for the depth at which the head rests on the throat when the person is lying down, normally 3-4 cm. This will not affect the patient's breathing, and the patient can breathe through the nasal cavity. Preferably, the anti-aspiration membrane 4 is made of elastic silicone plastic body (with enhanced flexibility and tear resistance), or it is made of ordinary medical silicone film by mold blow molding and then sterilization process.
[0029] Specifically, the mounting part 41 has hanging holes 411 on both sides, and the upper opening part 11 and the lower opening part 12 have hooks 111 on the inner side corresponding to the hanging holes 411. The anti-absorption film 4 is installed by hanging it on the hooks 111 through the hanging holes 411.
[0030] Specifically, in order to conform to the shape of the jawbone and reduce the foreign body sensation caused to the patient when the upper mouth opener 100 is used, the upper end of the upper mouth opener 11 is provided with an upper occlusal groove 112, and the lower end of the lower mouth opener 12 is provided with a lower occlusal groove 121. Specifically, in order to increase the slippage of human teeth when biting on the upper occlusal groove 112 and the lower occlusal groove 121 during assisted mouth opening, anti-slip textures 112a are provided on the groove surfaces of the upper occlusal groove 112 and the lower occlusal groove 121. The anti-slip textures 112a are preferably formed by laser etching, which makes the surface texture easier to shape. The preferred anti-slip textures 112a have a depth of 0.3 mm and a spacing of 1.5 mm.
[0031] Specifically, in order to prevent the damping hinge 3 from pressing against the mucous membranes on the left and right sides of the oral cavity, both the upper hinge arm 31 and the lower hinge arm 32 are arc-shaped. The arc shape also makes it easier to control the opening angle of the upper mouth opening member 11 and the lower mouth opening member 12. Preferably, the opening angle of the upper mouth opening member 11 and the lower mouth opening member 12 is adjusted to 0-60 degrees.
[0032] Specifically, both the left mouth opening component 100 and the right mouth opening component 100 are made of medical-grade silicone composite transparent material to facilitate observation of the liquid state inside the mouth. Furthermore, the surfaces of the left mouth opening component 100 and the right mouth opening component 100 are coated with a nano-silver antibacterial layer to achieve antibacterial standards. Preferably, the contact surface of the damping hinge component is coated with a titanium alloy to prevent allergies.
[0033] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
