Description

Technical Field

[0001] This utility model relates to the field of pediatric dental care technology, and in particular to a pediatric oral mouth opening device. Background Technology

[0002] Children face numerous oral health issues, including gingivitis, dental caries, oral ulcers, angular cheilitis, and pulpitis. During pediatric dental care, especially complex procedures, mouth openers are often used to facilitate oral care. A pediatric mouth opener is disclosed in publication CN221866093U. This mouth opener, when in use, can adapt to children of different heights by controlling a first moving plate, and can also clamp and fix the child's head through a clamping mechanism. Furthermore, an adjusting mechanism allows two support plates to perform relative L-shaped movements, automatically inserting the two support plates into the oral cavity and then moving them in opposite directions to expand and position the oral cavity.

[0003] Based on the above, it can be understood that although the pediatric oral mouth opener can expand and position the oral cavity during actual use, the shell and the second fixing plate are located directly in front of the child's face, which will block the child's face and prevent the child's oral cavity from being fully exposed to medical staff. Therefore, it is inconvenient for medical staff to perform oral care operations on the child. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing oral mouth openers for children, which can obstruct the operation of medical staff during use, and to propose an oral mouth opener for children.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a child oral mouth opener, including two opening mechanisms. Each opening mechanism includes a first fixed rod, on which a first fixed plate is fixed. A second fixed rod is rotatably mounted on the first fixed plate. A second fixed plate is fixed on both the second fixed rod and the first fixed rod. A support plate is fixed on each of the second fixed plates. The two support plates are symmetrically arranged. A positioning mechanism is provided between the first fixed rod and the second fixed rod.

[0007] Preferably, the tray has an inverted U-shaped structure, and the two second fixing plates are disposed between the two trays.

[0008] Preferably, the positioning mechanism includes an arc-shaped limiting rod, which is fixed to the first fixing rod. An arc-shaped hole is provided through the limiting rod, and the second fixing rod is provided through the hole. Multiple insertion holes are symmetrically provided on the limiting rod on both sides of the hole, wherein a positioning component is inserted between two of the insertion holes and the second fixing rod.

[0009] Preferably, the positioning component includes a stop bar, on which an insertion rod is fixed, and on which a rubber sleeve is fitted and fixed, and the insertion rod and the rubber sleeve both pass through two of the insertion holes and the second fixing rod.

[0010] Preferably, a connecting mechanism is fixed to both of the limiting rods.

[0011] Preferably, the connecting mechanism includes two connecting plates, which are respectively fixed on the two limiting rods, and an adjustment component is fixed between the two connecting plates.

[0012] Preferably, the adjusting assembly includes two connecting rods, which are respectively fixed to two connecting plates, and a cylinder is threaded onto both connecting rods.

[0013] The present invention provides a pediatric oral mouth opening device with the following advantages: when using the device, all four support plates can be used simultaneously or two of them can be used at the same time, so that when supporting the child's mouth, the area to be operated on during care will not be blocked. This facilitates the operation by medical staff and ensures the effectiveness of oral care for children. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figure 1 , 2 5 and 6, a child oral mouth opener, comprising two opening mechanisms, each including a first fixing rod 1, a first fixing plate 2 fixed to the first fixing rod 1, and a second fixing rod 3 rotatably mounted on the first fixing plate 2. The first fixing rod 1 and the second fixing rod 3 can be unfolded, thereby allowing the angle between the second fixing rod 3 and the first fixing rod 1 to be adjustable. A second fixing plate 4 is fixed to both the second fixing rod 3 and the first fixing rod 1, and a support plate 5 is fixed to each of the second fixing plates 4. The two support plates 5 are symmetrically arranged and have an inverted U-shaped structure. The inverted U-shaped structure of the support plate 5 can engage with the teeth when in contact, preventing the position of the support plate 5 from shifting when the child bites, thus ensuring the effectiveness of use. The two second fixing plates 4 are located between the two support plates 5. A positioning mechanism is provided between the first fixing rod 1 and the second fixing rod 3 to fix the adjusted second fixing rod 3 and the first fixing rod 1, thereby supporting the child's oral cavity.

[0023] When using this device, depending on the location of the child's oral cavity requiring local care, you can choose to use either two opening mechanisms or one opening mechanism. That is, all four trays 5 can be used simultaneously, or only two of them can be used. In specific operation, when the second fixing rod 3 and the first fixing rod 1 are closed, the two second fixing plates 4 drive the two trays 5 to be inserted into the oral cavity. The two trays 5 are secured to the upper and lower teeth. Then, the second fixing rod 3 and the first fixing rod 1 are opened, and the positioning mechanism is used to fix the second fixing rod 3 and the first fixing rod 1 at the adjusted angle. This ensures that when supporting the child's oral cavity, the area to be cared for is not obstructed, facilitating the operation of medical staff while ensuring the effectiveness of oral care for children.

[0024] Example 2: Based on Example 1, referring to... Figure 1-6As another preferred embodiment of this utility model, the difference from embodiment 1 is that the positioning mechanism includes an arc-shaped limiting rod 6, which is fixed on the first fixed rod 1. An arc-shaped hole 7 is provided through the limiting rod 6, and a second fixed rod 3 is provided through the hole 7. When the angle between the second fixed rod 3 and the first fixed rod 1 is adjusted, the second fixed rod 3 moves in the hole 7. Multiple insertion holes 8 are symmetrically provided on the limiting rod 6 on both sides of the hole 7. A positioning component 9 is inserted between two insertion holes 8 and the second fixed rod 3. The positioning component 9 is used to lock the second fixed rod 3 on the first fixed rod 1 after the angle is adjusted.

[0025] The positioning component 9 includes a stop bar 10, on which an insertion rod 11 is fixed. A rubber sleeve 12 is fitted and fixed on the insertion rod 11. The insertion rod 11 and the rubber sleeve 12 both pass through two insertion holes 8 and the second fixing rod 3. With the assistance of the rubber sleeve 12, the insertion rod 11 is more secure when inserted into the two insertion holes 8 and the second fixing rod 3, and is less likely to fall off.

[0026] When in use, move the second fixing rod 3. After the angle between the second fixing rod 3 and the first fixing rod 1 is adjusted, hold the stop bar 10 and insert the insertion rod 11 into one of the two insertion holes 8 and the second fixing rod 3. This will limit the second fixing rod 3 to the limiting rod 6, thereby locking the angle between the second fixing rod 3 and the first fixing rod 1, thus ensuring the effect of supporting the child's mouth.

[0027] Example 3: In Example 1, the two limiting rods 6 are set separately, and the two opening mechanisms are also set separately. Although this makes it convenient to choose to use one or both opening mechanisms, it makes one of the opening mechanisms easy to lose. (Refer to...) Figure 1 , 2 In embodiment 4, another preferred embodiment of the present invention, the difference from embodiment 2 is that a connecting mechanism is fixed on both limiting rods 6. The connecting mechanism includes two connecting plates 13, which are respectively fixed on the two limiting rods 6. An adjusting component is fixed between the two connecting plates 13. The adjusting component is used to adjust the distance between the two limiting rods 6, so that when the two opening mechanisms are used together, the distance between the two opening mechanisms is in a suitable position.

[0028] The adjustment assembly includes two connecting rods 14, which are respectively fixed on two connecting plates 13. A cylinder 15 is threaded onto both connecting rods 14. By turning the cylinder 15, the two connecting rods 14 can rotate together inside the cylinder 15, thereby adjusting the length of the two connecting rods 14 protruding from the cylinder 15, and thus adjusting the distance between the two opening mechanisms.

[0029] When both opening mechanisms need to be used, keep the two limit rods 6 and the two connecting plates 13 from rotating, and turn the cylinder 15 to move the two limit rods 6 and the two connecting plates 13 away from or closer to each other, thereby adjusting the working distance between the two opening mechanisms.

[0030] When only one opening mechanism is needed, one of the connecting rods 14 can be disengaged from the cylinder 15, or one of the connecting rods 14 can be twisted to make the two opening mechanisms move up and down, so that only one opening mechanism can be used.

[0031] Furthermore, by utilizing the cooperation of two connecting rods 14 and cylinder 15, the two opening mechanisms are connected together, thus avoiding the problem that one of the opening mechanisms is easily lost.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
