RU197533U1 - Device for mechanical cleaning of the entire dentition of a person - Google Patents

Abstract

The present invention relates to the field of medical technology and is intended for mechanical cleaning of the entire dentition of a person simultaneously with a gear system of movement. The device is made in the form of a mouthpiece with a system of holes designed for gears. The mouthpiece covers the entire surface of the teeth, so the brush frame includes two arcuate bases fastened together. The brush contains a handle that includes a drive mechanism that transmits rotational movements from the engine to the movable elements of the brush (gears, shafts). The gears are located along the contour of the dentition of a person and have bristles on their surface for mechanical cleaning. From gears, movement is transmitted to shafts with gears to clean the occlusal surface of the upper and lower molars. The device allows you to simultaneously clean the entire surface of the teeth in a few seconds, removing the human factor.

Description

State of the art

From the current level of technology there is known an analogue made in the form of a mouthpiece, including mechanical cleaning elements with different sections of bristles for different tooth areas (patent RU 2550429, publ. 05/10/2015), which consists of a frame in the shape of a mouthpiece and mechanical cleaning modules integrated into it. .

The disadvantage of this system, despite the real effectiveness in individual settings, is that it requires the participation of a specialist, which includes significant additional costs and requires a lot of time.

Accordingly, it is desirable to provide a mouthguard device that can be easily individually customized by the user to adapt to the user's intraoral geometry, in particular to different widths and lengths. Another disadvantage of this device is the technology of toothbrushing, which is a linear motion or vibration.

Also known is a device in the form of a mouthguard for brushing teeth with adjustable arc length and / or arc width (patent RU 2620344, publ. 17.12.2012). This device also includes a tuning system for the geometric parameters of the human oral cavity.

The disadvantages of this technical solution are mechanical cleaning modules that do not allow to affect the entire surface of the dentition, due to which, the effectiveness of the device becomes insufficient for the personal hygiene procedure.

SUMMARY OF THE INVENTION

The present invention relates to a device for brushing human teeth. The problem to which the invention is directed is the implementation of a highly effective cleaning procedure. An automated device in the form of a mouth guard minimizes or eliminates the human factor in the process of personal care, thereby reducing the likelihood of errors when brushing your teeth.

The device allows you to clean the entire dentition of a person at the same time due to the design of the cleaning part, made in the form of a mouthpiece 1 with a system of holes for the gears 9, 10, 11 located along the teeth from the outside and inside. Also, the design allows you to clean the occlusal surface of the teeth due to the rotating shafts with gears 4.

Each rotating element of the brush has holes in which tufts of bristles are inserted to effect mechanical cleaning of the tooth surface and interdental spaces.

The electric motor located in the handle 1 of the device has a gear on its axis, which transmits movement to the drive mechanism 3, which consists of two elements. The drive elements 3 in turn transmit rotation to the two main gears 12 by means of a notch on the rivets 7 located on the frame of the brush 1.

Rotating brush elements transmit rotation to each other due to teeth.

Each gear 9, 10, 11 has rivets 7, 8 on the outside of the cap 1, designed to hold the gears in the holes of the frame 1.

On the shafts 4 for cleaning the occlusal surface, the movement is transmitted through the last two gears 9. The shafts 4, in turn, transmit the movement to the gears located on the inner side of the frame.

Thanks to this design, the correct cleaning technique is carried out from the gums to the tips of the teeth.

The disadvantage of this technical solution is the impossibility of adjusting the mouthpiece for the personal geometric parameters of the jaw of a person.
