Description

Technical Field

[0001] The utility model belongs to the technical field of oral medical instruments, and in particular relates to a handheld child oral cavity caries prevention fluoridation applicator. Background Art

[0002] Caries refers to the chronic and progressive destruction of hard tissues such as teeth under the influence of multiple factors such as bacteria. Children generally have a higher rate of caries due to insufficient mineralization of deciduous teeth, large spaces between teeth, and a delicate diet and strong food adhesion. Currently, the most common method of preventing caries in clinical and household use is topical fluoride, which refers to the direct application of fluoride to the tooth surface in different ways to inhibit tooth demineralization, promote remineralization, and increase the tooth's resistance to caries. Fluoride application refers to the method of applying fluoride-containing paint (an organic solvent with fluoride added) to the surface of teeth to prevent caries. The most common fluoride application method in clinical practice is for children to lie flat on the dental chair in the clinic, and medical staff use a small brush to dip an appropriate amount of paint and apply it to the teeth in the child's mouth in turn. This process requires the cooperation of the child and is inconvenient to apply.

[0003] The current fluoride application method has many shortcomings: a. Children's cooperation is poor. Many child patients with dental phobia need a long period of verbal and behavioral comfort and help from the time they enter the clinic to normal treatment. Therefore, they have many difficulties in cooperating with fluoride application, and the clinical operation takes a long time; b. It is inconvenient to dip the fluoride-containing paint with a small brush, and there is a risk of spilling and contamination of the paint during the process, resulting in waste; c. The amount of paint dipped by the small brush each time is not uniform, resulting in uneven fluoride agent on the surface of each tooth in the mouth; d. During the coating process, which lasts for 2-3 minutes, the child needs to maintain a certain degree of mouth opening, which makes it difficult to cooperate. Child patients have vigorous saliva secretion in their mouths. During this process, saliva contaminates the tooth surface and fluoride agent, which will also affect the effect of fluoride application to prevent caries. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a handheld children's oral anti-caries fluoride applicator to solve the deficiencies in the prior art.

[0005] In order to achieve the above object, the utility model is implemented by the following technical solutions:

[0029] See also Figure 1 , Figure 2 , Figure 3 As shown, the utility model of the handheld children's oral anti-caries fluoride applicator comprises an isolation sleeve 1 and an elastic extruder 2, wherein the isolation sleeve 1 comprises an upper jaw isolation sleeve 11 and a lower jaw isolation sleeve 12, the upper jaw isolation sleeve 11 is formed by a maxillary lip-cheek surface 111 and a maxillary lingual-palate surface 112 adapted to the child's upper jaw tooth shape, and the lower jaw isolation sleeve 12 is formed by a mandibular lip-cheek surface 121 and a mandibular lingual-palate surface 122 adapted to the child's mandibular tooth shape, and the two ends of the upper jaw isolation sleeve 11 and the lower jaw isolation sleeve 12 are respectively connected to form a whole at the end of the molar, and there is a gap 13 running through the entire occlusal surface between the occlusal surfaces of the upper jaw isolation sleeve 11 and the mandibular isolation sleeve 12.

[0030] Continuing to refer to the figure, the elastic extruder 2 includes a U-shaped elastic sheet 21 and a handle 22 connected to each other. The arc length and thickness of the U-shaped elastic sheet 21 are respectively suitable for the arc length and upper and lower widths of the gap 13. The extension surface size of the U-shaped elastic sheet 21 is suitable for the extension surface size of the occlusal surface. A plurality of fine perforations 211 are distributed on the surface of the U-shaped elastic sheet 21, which help the fluorine agent to be conducted to the dentition under the action of the occlusal force with the help of atmospheric pressure. The fine perforations 211 become overflow channels, and the overflowed fluorine agent can be evenly distributed on the upper and lower tooth surfaces.

[0031] In a preferred embodiment, the main body of the handle 22 is rod-shaped and one end is fixed to the middle part of the U-shaped elastic sheet 21, and the other end of the handle 22 is a sphere. It is understandable that there is no special restriction on the shape of the handle 22 and the connection method with the elastic sheet. The handle 22 can be personalized, for example, it can be designed as a cartoon pattern or a sphere, which is more in line with the characteristics of children's use and can be customized by a special person, which helps the children to establish a sense of belonging to the item and helps to carry out subsequent clinical treatment. The entire elastic extruder 2 is similar to a lollipop stick, which echoes the fruity taste of clinical fluoride agents and is more easily accepted by children.

[0032] The thickness of the U-shaped elastic sheet 21 is 3-5 mm, and accordingly, the thickness of the gap 13 is also 3-5 mm to allow the elastic sheet to be inserted.

[0033] The isolation sleeve 1 and the U-shaped elastic sheet 21 are both made of silicone, and the isolation sleeve 1 is relatively hard. In order to achieve a better fluorine coating effect, the isolation sleeve 1 is made of a slightly harder silicone material, and the elastic extruder 2 is made of a slightly softer silicone material, so that different hardnesses are helpful for the loading and removal of the elastic extruder 2, and also help to improve the overflow efficiency of the fluorine agent.

[0034] The isolation sleeve 1 is adapted to the tooth shape of the deciduous dentition, the tooth shape of the replacement dentition, or the tooth shape of the permanent dentition of the child.

[0035] When the fluoride applicator is in use, the medical staff evenly applies the fluoride agent on the upper and lower surfaces of the elastic sheet of the elastic extruder 2, then inserts the elastic sheet of the elastic extruder 2 into the isolation sleeve 1, and places it in the child's mouth according to the corresponding positions of the upper and lower jaws, and asks the child to gently bite the elastic sheet several times and keep it in the mouth for about one minute, and the fluoride application operation is completed.

[0036] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
