Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for cleaning the inside of the oral cavity, and in particular, while scratching off dirt in the oral cavity,
The present invention relates to a device for removing dirt scraped off from the oral cavity.

[0002]

2. Description of the Related Art A conventional device for scraping dirt in an oral cavity is provided with a brush for scraping dirt in the oral cavity and a suction port for removing the scraped dirt from the oral cavity. , Prepare for the tip of the instrument.

[0003]

SUMMARY OF THE INVENTION In accordance with the present invention, the tip portion of an appliance that comes into contact with mucous membranes, tongues and / or teeth in the oral cavity, which has not been achieved by prior art appliances for scraping dirt in the oral cavity, has been proposed. Achieve a reliable supply of cleaning fluid. Furthermore, it is possible to achieve a reliable recovery of the released cleaning fluid.

[0004]

A cleaning device for oral cavity according to the present invention is provided with a tip for contacting mucous membrane, tongue and / or teeth in the oral cavity and is moved in the oral cavity. (Preferably brush bristles, porous sponge, etc.)
And a support portion that is more rigid than the cleaning portion that supports the cleaning portion, and an opening is provided at a position fixed to the handle portion and the cleaning portion, which is designed to be held by the operator's hand. And a washing fluid conduit for discharging the washing fluid to a portion of the cleaning portion other than the tip, preferably near the root of the brush bristles. In accordance with the present invention, the irrigation fluid conduit allows irrigation fluid to flow from a fixed position relative to the cleaning portion to a portion of the cleaning portion other than the tip that contacts the mucosa, tongue and / or teeth in the oral cavity. Therefore, the cleaning fluid flows along the cleaning portion by capillarity or adhered flow on the cleaning portion, and then to the tip where the cleaning portion moves while contacting the mucous membrane, tongue and / or teeth in the oral cavity. It is ensured that the cleaning fluid does not reach the mucous membrane in the oral cavity, tongue and / or teeth other than the mucous membrane, the tongue and / or the tooth, which contacts the tip of the cleaning portion without passing through the cleaning portion. Further, since the cleaning fluid is guided to the tip of the cleaning portion after reaching the portion of the cleaning portion other than the tip, the cleaning fluid is washed between the portion of the cleaning portion other than the tip and the tip of the cleaning portion. The fluid diffuses on the cleaning portion, and the cleaning fluid diffuses sufficiently over the entire tip of the cleaning portion to scrape off the dirt at the tip of the cleaning portion and from the tip of the cleaning portion of the scraped dirt. Effectively works for removal. In order to achieve this effect, the material of the cleaning portion and the positional relationship between the cleaning portion and the opening on the intraoral cleaning device are irrelevant. For example, even if the opening is arranged outside the cleaning portion. It is possible to achieve the above effects.

When the fixed position is arranged between the operator's hand and the cleaning portion, the opening of the cleaning fluid conduit is arranged closer to the outside of the oral cavity than the cleaning portion.
Entry into the oral cavity deeply is prevented by the cleaning portion. If the cleaning portion has a suction port for sucking the cleaning fluid, and has a cleaning portion extending around the opening and the suction port, for example, forming a substantially U-shape, the cleaning fluid flowing out from the opening will be absorbed in the oral cavity. After reaching the mucous membrane, tongue and / or teeth of the subject, the flow is restricted so that the fluid is restrained in the area sandwiched by the cleaning part and sucked into the suction port, and the wash fluid that has flowed out is almost completely absorbed by the suction port. It becomes possible to absorb. Even if the cleaning portion is a brush composed of an array of a plurality of filament bundles, a strong suction pressure is generated between the filament bundles of the brush due to the negative pressure of the suction port, and the filament bundles It is restrained that the cleaning fluid flows out to the outside of the cleaning portion from between.

When the cleaning fluid is directed by the cleaning fluid line away from the suction port and flows out from the cleaning fluid line, the cleaning fluid is prevented from being sucked into the suction port without reaching the cleaning portion. , Most of the cleaning fluid surely reaches the cleaning portion other than the tip, reaches the tip, and then
It will be sucked into the suction port. When a fixed position is arranged between the suction port and the cleaning portion, the cleaning fluid flowing out from the opening of the cleaning fluid conduit is either reaching the cleaning portion or being sucked by the suction port. Cleaning fluid
It is prevented from being directly supplied into the oral cavity other than the mucous membrane, tongue and / or teeth in the oral cavity that come into contact with the cleaning portion, that is, outside the oral cavity cleaning device.

The cleaning portion is arranged within the range in which the cleaning fluid that has been directed by the cleaning fluid conduit and flows out from the cleaning fluid conduit is diffused, and the cleaning fluid that has flowed out of the cleaning fluid conduit is mostly mucous membrane in the oral cavity. When reaching the cleaning portion before reaching the tongue and / or the teeth, most of the cleaning fluid flowing out from the cleaning fluid line is surely caused by the capillary phenomenon or viscous flow on the cleaning portion to ensure the tip of the cleaning portion. It is guided toward the mucous membrane in the oral cavity, the tongue and / or the teeth that come into contact with, and effectively works to scrape off the dirt at the tip of the cleaning portion and to remove the scraped dirt from the oral cavity. When the cleaning fluid is directed by the cleaning fluid conduit and flows out from the cleaning fluid conduit containing the flow direction component that separates from the supporting portion and approaches the tip of the cleaning portion, and reaches a portion of the cleaning portion other than the tip, cleaning is performed. The cleaning fluid flowing out from the fluid conduit is guided more reliably toward the tip of the cleaning portion that comes into contact with the mucous membrane, tongue and / or teeth in the oral cavity, and scrapes off and scrapes dirt on the tip of the cleaning portion. Effectively removes dirty dirt from the mouth.

[0008] When the irrigation fluid line penetrates through the handle portion, the irrigation fluid line is connected to an inhalation source (for example, a vacuum pump) outside the oral cavity cleaning device while being accommodated in the oral cavity cleaning device. It becomes possible to introduce the irrigation fluid line into the oral cavity very easily. If the portion of the cleaning portion other than the tip to which the cleaning fluid is supplied is the boundary between the cleaning portion and the support portion, the distance to the tip of the cleaning portion for diffusion of the cleaning fluid on the cleaning portion is increased. In addition to being well taken, diffusion of the cleaning fluid over the support portion can also be used to achieve dispersion of the cleaning fluid over a wider area of the cleaning portion.

The end of the suction port (along the surface of the support portion,
Projection in the direction of approaching the tip of the cleaning part from the support part with respect to the suction port (surrounding most of the suction port) and the end of the opening of the cleaning fluid line (along the majority of the opening along the surface of the support part) If the support portion has a barrier between the suction port and the opening of the cleaning fluid conduit, the cleaning fluid flowing out from the opening of the cleaning fluid conduit is suppressed from flowing toward the suction port, and is sucked. Flow toward the supporting portion other than the mouth or the cleaning portion is promoted, and the cleaning fluid is prevented from being sucked into the suction port without passing through the tip of the cleaning portion. If the shortest distance between the suction port and the opening of the cleaning fluid conduit is larger than the shortest distance between the cleaning portion and the opening of the cleaning fluid conduit, the cleaning fluid flowing out from the opening of the cleaning fluid conduit is sucked. The flow toward the cleaning portion is suppressed while the flow toward the mouth is suppressed, and the cleaning fluid is prevented from being sucked into the suction port without passing through the tip of the cleaning portion.

When the cleaning fluid flows out from the cleaning fluid line to the support portion, diffuses on the support portion, and reaches the portion of the cleaning portion other than the tip, the cleaning fluid is dispersed to a wider area of the cleaning portion. It becomes possible. When the dirt on the mucous membrane, tongue and / or teeth in the oral cavity is scraped off and the scraped dirt is sucked, a cleaning fluid is applied to the mucous membrane, tongue and / or
Or to a part of the cleaning part other than the tip of the cleaning part that comes into contact with the teeth,
Supply from a position fixed to the cleaning unit, and after passing at least a part of the cleaning fluid through the cleaning unit other than the tip,
If it reaches the tip of the cleaning unit, the cleaning fluid is prevented from being directly supplied to the mucous membrane, the tongue, and / or the teeth in the oral cavity without passing through the cleaning unit, and the dirt is scraped off or scraped off. No unnecessary cleaning fluid is supplied for sucking dirt, and the cleaning fluid can be supplied to the tip of the cleaning unit after being sufficiently diffused on the cleaning unit.
