Description

The invention relates to bristle-buccal products, in particular to dental babies;

The aim of the invention was to increase the effectiveness of toothbrushing due to the achieved ability to affect their interfacial surfaces in interdental spaces. Achieving this goal ensures the completeness of toothbrushing from all sides. The destruction of teeth on these adjacent surfaces is prevented, food particles are usually delayed and, as a breeding ground for the development of microbes, cause tooth decay. Along with the processing of these generally inaccessible surfaces, acceleration of the treatment is also achieved - by providing the possibility of cleaning the upper and lower teeth immediately from different sides.

The essence of the invention consists in the fact that rectangular pockets of sufficient length are formed on the working bristle head for placement of teeth and for horizontal working path of the head. The presence of such pockets allows ramming arrays of the bristle massifs to be processed on the tooth series at a right angle. In this case, the bristles act not only on the frontal, apical and back sides of the teeth, but also penetrate into the interdental cavities, freeing them from food debris and cleaning the adjacent lateral sides of the teeth.

The rectangular shape of the said pockets is essential. The right angles between the bristle arrays lining the pocket and also between the walls supporting them provide a right angle for the bristles to collide with the dentition and thereby allow the bristles to penetrate into the interdental spaces.

Of great importance is the different length of the bristles of the moving massifs, as well as the uniformity of the dispersion of different lengths of bristles among themselves inside the array. Thus, shortened bristles allow long bristles opposing the interdental grooves to freely penetrate these grooves. And for those long bristles that fall on the convex parts of the teeth, the shortened bristles leave an inter-arched space for deflection. The latter circumstance is also necessary for the penetration of long setae falling on the interdental depressions - deep into the latter. The uniform dispersal of both bristles among themselves ensures freedom of the aforementioned deflection.

An essential feature is the elasticity of the isthmus, which facilitates the access of the working nipple to the back (molar) teeth and eliminates the need to forcefully push the corner of the mouth and cheek. Moreover, the flexibility of the isthmus makes it possible to maintain the constancy of a right angle between the head and the treated area of the dentition. This is necessary to maintain the penetration of the bristles into the interdental cavity. The elasticity of the isthmus ensures, at the same time, the reversibility of its bends - i.e. returning to its original position without the risk of self-destruction, the second property of the isthmus - to bend exclusively around the vertical axis - eliminates the risk of distortions that jam the brush against the teeth.

Unlike the prototype, the pads of the working head are made in one piece. This provides a reduction in the size of the head vertically, which is important in conditions of limited space of the oral cavity. At the same time, the monolithic design of the head gives it an H-shape and thereby increases the rigidity and strength of the head, which is important for maintaining its rectangular configuration during operation and, therefore, for maintaining the ability of the bristles to penetrate into the interdental cavities.

The bottom of each pocket is covered with shortened bristles for intensive processing of the tops of the teeth during the run of the working head.

A tube of paste, used as a handle through the threaded connection of its fitting with an isthmus detachable sleeve, facilitates the cleaning process by the fact that human fingers, when exposed to the tube during cleaning, automatically squeeze a new portion of the paste as it is consumed.

Thus, an increase in the effectiveness of toothbrushing is achieved due to the presence of the listed new design features: solidity of the body

5 heads, achieved by completing the blocks in one piece, reinforced H-shape of the head, uniform alternation of the lengths of the bristles on the vertical walls of the blocks, uniformity and rooted lengths

0 bristles on horizontal walls, rectangular pockets of the head, isthmus flexibility reversible exclusively around the vertical axis, tube handle with paste, isthmus coupling with threaded connection to the tube fitting.

The listed features are necessary and sufficient to achieve the above goals and are structurally linked to each other as components of a single device. Moreover, these features are not found in similar devices, which determines their novelty as significant.

. In FIG. 1 is a front view of a toothbrush; FIG. 2 - from above; in FIG. 3 - side view;

5 of FIG. 4 schematically reflects the central and lateral position of the brush in the oral cavity (top view). Figure 5 represents the connection of the isthmus of the brush to the tube, and Figure 6 - axial execution of the isthmus.

0 The toothbrush contains a handle 1 and a working end (head), consisting of vertical walls 2, 3 of the upper block 23 and vertical walls 25,26 of the lower block 24. Both pads are made in one piece

5 in such a way that they have monolithically fused bases in the form of a common bridge-base 20. As a result, the head has an H-shaped appearance (Fig. 3). By means of the flexible neck 7, the handle 1 and the head are movably connected. Mobility is ensured by the elasticity of the material from which the isthmus is made, or due to a detachable connection assembled for osig relative to which the head and handle

5 rotate relative to each other. In this way, a detachable connection 32 is made on the vertical axis 31 (Fig. 6).

Between the vertical walls 2 and 3, 25 and 26 are the upper and lower pockets 13,14. The bottom of each of them is covered with identical short bristles 6. The inner side surfaces of the pocket 13 are covered with arrays 4, 5 of bristles of various lengths (± 1-2 mm), and the surfaces of the pocket 14 are covered with arrays 15, 16 of the same bristles. The teeth to be machined 17, 18 of the upper and lower rows are placed respectively in the pockets 13, 14.

The handle 1 is cylindrical, the floor, the weight of the end hole includes a cylindrical plunger (pusher) 9. Its surface - as well as the inner surface of the cavity of the handle 1 - is coated with a thread along which the plunger can be screwed into the cavity of the handle 1. The protrusion 11 is for fingers .

From the head side, the cavity of the handle 1 passes into the channel 8, which is bifurcated into its upper and lower branches, which open on the bristle surfaces of the pockets 13 and 14 with the mouths 12 and 19. The arrow in FIG. Figure 3 shows the direction of brush movement.

The handle 1 can be replaced with a tube of paste - then at the end of the neck of the isthmus 7 remote from the head there is a sleeve 28 with a thread 29 into which the nozzle 27 of the tube 30 is screwed. Then the paste is supplied without a plunger - by extrusion of fingers from the tube by squeezing the latter . In this case, the paste from the tube enters through the fitting into the cavity of the channel 8, in its branches and on the bristles (Fig. 5).

The outer edges (right angles) of the bristle arrays 5 and 15 (Fig. 3) can be rounded, i.e. shaved - in the form of a brush for persons with protruding posterior gums.

The prototype was made from parts of industrially manufactured toothbrushes (head), from molten molten polyethylene (isthmus 7) and from plastic tubes (handle 1 and plunger 9). The height of the walls of the head in total vertical (Fig. 3) is 2.3 cm, the width of these walls is 1 cm, and the thickness is 6 cm; the distance between them is 3.4 cm. The thickness of the base is 20-6 cm. The length of the bristles of the arrays 4, 5, 15, 16 is 5-7 cm, and for the bristles is 6-3 mm.

When using the brush, take the fingers by the handle 1, with the fingers of the other hand - by the protrusion 11 and unscrew the plunger 9 from the handle 1 completely. Toothpaste is introduced into the cavity of the handle 1 - squeezing it from the tube into the cavity. Then screw the plunger into the cavity of the handle 1, compressing the paste and squeezing part of it through the channel 8, its branches and holes 12, 19 onto the bristles of the arrays 4, 16. Then, the brush head is inserted into the mouth so that the teeth of the upper row are in pocket 13, and the lower r yes - in

pocket 14. By moving along the arrow (Fig. 3), the ends of the bristles act on the teeth. Longer (7 mm) setae coming to the interdental spaces

adjacent teeth of the same row penetrate these gaps and clean the tooth enamel in these places. Brushes of known samples do not provide this. Bristles 5-6 mm long of the corresponding vertical wall (2 or 3 or the like) act on the front or back surfaces of the teeth, respectively. Moreover, the long bristles that came to the same surfaces slightly bend into their own intervertebral spaces.

They perform 2-3 cycles of brushing in one place and then move to an adjacent area of the dentition, etc. They try to maintain a straight (at an angle of 90 °) direction of movement of the bristles on the teeth. When processing the posterior teeth, this is ensured by the bending of the isthmus 7 - as shown in FIG. 4. Bending the isthmus is also useful in preventing overgrowth of the mouth (lips).

When brushing your teeth, the penetration of the bristles into the interdental spaces is felt, accompanied by a pleasant sensation of massaging the gums.

The effectiveness of the invention lies in the fact that the distinguishing features ensure the penetration of the bristles into the interdental spaces, the effective cleaning of the tooth j enamel in these areas (previously unacceptable) and,
