Description

Papanicolaou toothbrushes

technical field

The invention relates to the technical field of toothbrushes, in particular to an auxiliary toothbrush for the Pasteur brushing method.

Background technique

The Bass Method, also known as gingival sulcus sweeping method or horizontal vibration method, can effectively remove plaque near the gingival margin and in the gingival sulcus and massage the gums. It is a toothbrushing method recommended by the American Dental Association. The key is: use a soft-bristled toothbrush, the toothbrush and the long axis of the tooth point at the root tip at an angle of 45°, apply light pressure, so that part of the bristles enter the gingival sulcus, and part of the bristles are located on the gingival margin, and extend into the adjacent space as much as possible. Vibrate horizontally back and forth with gentle pressure, and brush each part 10 times; the toothbrush can be vertically placed on the lingual and palatal side of the anterior teeth, and the top of the bristles enters the gingival sulcus and adjacent spaces at an angle of about 45°, and vibrates along the long axis of the teeth.

However, because the Pap brushing method has certain requirements on the technique and is not easy to form a habit, most people have not adopted the Pap brushing method. It is difficult for traditional toothbrushes to easily meet the requirements of this correct brushing method: 1. The shape of the toothbrush surface composed of bristles is difficult to meet the cleaning requirements of "the top of the bristles enters the gingival sulcus and adjacent spaces at an angle of 45°"; 2. The traditional nylon bristles are sharper, The relative friction speed of the contact toothbrush is faster, and it is easier to puncture the gums when performing the Papanicolaou method; 3. The design of the brush surface of the existing toothbrush is easy to guide the user to the wrong horizontal brushing posture, and the vibration frequency is too fast and the strength is too large. Formation of tooth wedge-shaped defects.

Contents of the invention

The technical problem to be solved by the present invention is: it is difficult for traditional toothbrushes to conveniently meet the needs of the correct tooth brushing method of Pasteur brushing. The present invention provides an auxiliary toothbrush for Pasteur brushing, which is beneficial to overcome the shortcomings of traditional toothbrushes and facilitates the operation of Pasteur brushing. Steps to brush your teeth.

The present invention realizes through following technical scheme:

Auxiliary toothbrush for Pasteur brushing method, including a brush handle and a brush head, the brush head is in a cube structure, a central bristle is planted at the geometric center of the front plate of the brush head, and a middle layer is planted around the central bristle from inside to outside in turn Bristles and bristles of the outer layer; the length of the bristles of the middle layer is greater than that of the bristles of the central layer and shorter than that of the bristles of the outer layer.

The working principle of the present invention is as follows: the toothbrush includes a toothbrush head with a small size and a brush handle, bristles are planted on the brush surface of the brush head, and the brush surface formed by the bristles forms a central region where the bristles are shorter than the bristles in the middle layer, and the bristles in the middle layer are shorter In the shape of the outer layer of bristles, and the middle layer of bristles and the outer layer of bristles gradually spread outward. The outer layer of bristles surrounding the middle layer of bristles is used to clean the gums, adjacent spaces, and the spaces between adjacent teeth; at the same time, the small-sized brush head is convenient for cleaning all sides of the teeth, and it is easy to reach into the back of the dental arch to clean the last molars that are difficult to clean . Specifically, during use, when cleaning the lip (buccal) surface and tongue (palatal) surface of the teeth, the user holds the brush handle so that the central bristles are placed in the center of the tooth surface, and the middle bristles guide the outer bristles into the gingival sulcus and adjacent areas. Gap and the gap between adjacent teeth, gently clean and massage the gums when vibrating horizontally, and the central bristles can be used to effectively clean the pits and fissures of the tooth surface and occlusal surface.

Preferably, both the bristles of the middle layer and the bristles of the outer layer are gradually unfolded, and the angles of the bristles of the middle layer and the bristles of the outer layer are both 45°.

Preferably, auxiliary bristles are planted around the outer layer of the bristles of the outer layer, and the auxiliary bristles are made of silica gel, and the length of the auxiliary bristles is one-third of the length of the bristles of the outer layer.

The outer layer is provided with auxiliary bristles whose length is one-third of the outer layer bristles, which are mainly used to form a support structure for the outer layer bristles, preventing the outer layer of bristles from spreading out excessively after the toothbrush has been used for a period of time, making it difficult to contact the gums and adjacent spaces. Perform cleaning operations.

Preferably, the central bristles are made of spiral nylon bristles, the middle bristles are made of silicone bristles, and the outer bristles are made of Bincho charcoal bristles.

The bristles in the central area of the present invention are spiral nylon brush filaments with a low friction coefficient, and the middle layer bristles are thicker, slightly longer, and higher friction coefficient silicone bristles, which gradually spread out from the center to the surroundings, and reach an angle of 45° to the outermost layer. , The thicker middle bristles provide support for the outer bristles to expand outwards, making them less prone to deformation. The outer layer of bristles surrounding the silicone bristles is a blunt-ended Bincho charcoal brush filament, which is suitable for cleaning the position of the gums and adjacent spaces without damaging the gums; the surface of the middle layer of bristles forms a rough friction surface to form an eraser-like effect; When cleaning the occlusal surface of the back teeth, the spiral nylon bristles can effectively clean the pits and fissures. The materials of the bristles of each layer are different, and they have a good cleaning effect on the gingival sulcus, adjacent spaces, smooth surfaces of teeth, and pits and fissures. The molars have a good cleaning effect.

Preferably, the brush handle includes a connecting handle and a handle, and the connecting handle and the handle are provided with perforations extending in the axial direction and coaxial with the central line; one end of the handle in the axial direction is provided with a The airbag is perforated and connected; the other axial end of the handle is detachably connected to the connecting handle, and the perforation in the connecting handle at the connection is in sealing communication with the perforation in the handle; the brush head is provided with a hollow chamber, and A number of through holes are opened on the front plate corresponding to the hollow chamber, the other axial end of the connecting handle is connected to the brush head, and the perforation in the connecting handle communicates with the interior of the hollow chamber.
