By forming a drain hole 18 at the surface of the recess part 12, the jet liquid and waste liquid used for washing are drained from the inside of the mouth to the outside of the mouth to secure the safety of washing using a water current inside of the mouth, to eliminate the occurrence of the non-contacting place at all the surfaces of the teeth and gums and all the gaps between them, and to realize reliable washing of all the surfaces of the teeth and gums and all the gaps between them. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a jig for jetting a liquid such as water to teeth and gums and cleaning the teeth and gums.

A cleaning brush using a brush is disclosed as a method for simultaneously brushing teeth in a patent publication (for example, see Patent Document 1).
JP2003-180718A (Claim 1).

As a method for cleaning teeth and gums, brushing with a toothbrush is generally used, but there is a problem that brushing inevitably causes non-contact parts and cleaning residue at non-contact parts. It was.

In addition, in “JP-A-2003-170718” published as a method for brushing teeth, a method for brushing the front and back of teeth simultaneously is disclosed, but cleaning by bringing a solid called a brush into contact is defined. However, the problem that only the contact portion was cleaned and the non-contact portion was not cleaned remained.

  In addition, at the dental treatment site, water or air is used to wash the treatment site by water discharge (breezing) from one spill, but the cleaning tool used in the treatment is a person other than the person himself / herself. Is a cleaning tool that functions in a state where the cleaning part can be seen well, does not have a function of discharging water generated during cleaning, and is discharged by a separate device, and is a function for doctors to use for treatment to the last In daily life, it did not have a function as a cleaning tool for daily dental maintenance.

  Therefore, an object of the present invention is to embody a method and a jig for eliminating a non-contact portion in the cleaning of teeth and gums and surely cleaning all surfaces and gaps of the teeth and gums.

The cleaning tool for cleaning teeth and gums according to the present invention is a cleaning tool of a size that can be held in the mouth, and has a recess that allows teeth to enter the cleaning tool head 11 of the cleaning tool. In addition, the recess surface has two or more holes and one or more holes on the outer surface other than the recess, and the holes on the recess surface and the holes on the outer surface other than the recess are located inside the cleaning tool head 11. The first feature is that the liquid is in a connected state, the liquid enters from the hole on the outer surface, and the liquid is ejected from the hole on the concave surface.

A second feature of the cleaning tool for cleaning teeth and gums according to the present invention is that the concave portion of the cleaning tool head 11 is a U-shaped groove arranged in a row of teeth.

A third feature of the cleaning tool for cleaning teeth and gums according to the present invention is that U-shaped grooves are formed on two upper and lower surfaces of the cleaning tool head 11.

  A fourth feature of the cleaning tool for cleaning teeth and gums according to the present invention is that the cleaning tool head 11 has two or more holes on the outer surface other than the recesses. There are two or more paths in which the holes on the concave surface are connected independently, a path through which liquid enters from the holes on the outer surface, and liquid is ejected from the holes on the concave surface, and a cleaning tool that takes in the cleaning waste liquid from the holes in the concave surface And a path for discharging from the hole on the outer surface of the head 11.

The fifth feature of the cleaning tool for cleaning teeth and gums according to the present invention is that each of the front surface A and the rear surface B of the cleaning tool head 11 has holes, and these holes are located inside the cleaning tool head 11. It has a connected structure.

  According to the present invention, it is possible to uniformly contact the teeth and gums with the liquid sprayed from two or more holes at a time on the front and back surfaces of the teeth and gums and the tip of the teeth. With regard to the tooth and gum cleaning method using the toothpaste, it is possible to reliably clean the gap between the teeth, which is likely to be a non-contact location, and can greatly contribute to the daily maintenance of the teeth and gums.

  Further, in the present invention, the liquid is uniformly contacted to all teeth and gums by the structure in which the concave portion of the cleaning tool is a U-shaped groove with teeth arranged and the U-shaped groove is formed on the upper and lower surfaces of the cleaning tool. Even without the need for cleaning techniques, the backside of the back teeth and the gaps between the back teeth, which were difficult to clean by brush cleaning, can be reliably cleaned, enabling easy and stable cleaning of teeth and gums. Become.

  Further, according to the present invention, there are two or more paths that have two or more holes on the outer surface other than the recess of the cleaning tool, and the holes on the outer surface and the recess surface are independently connected inside the cleaning tool. A structure having a path through which liquid enters from the hole on the outer surface and ejects liquid from the hole on the concave surface, and a path for discharging the cleaning waste liquid from the hole on the concave portion via the hole on the outer surface of the cleaning tool, or the cleaning tool By having holes on the front surface A and the rear surface B of the head 11 and connecting these holes inside the cleaning tool head 11, the liquid used for cleaning is stably discharged from the mouth. It is possible to implement a cleaning tool that can be safely cleaned even if it is inserted into the mouth and the teeth and gums are cleaned using a water flow.
