Description

Current-transmitting mouthpiece

Technical Field

The utility model relates to the field of medical health care instruments, in particular to a tooth socket for transmitting current.

Background

Referring first to fig. 1, the mouthpiece shown in fig. 1 is a conventional mouthpiece for delivering therapeutic current to the gums of a user. In fig. 1, the conductive silicone gel 1 is positioned on the inner upper part of the mouthpiece to form an elongated strip facing the gum. The conductive silica gel 1 can be attached to the gum tissue of a user only by the thickness, but the too shallow thickness can prevent the tooth socket from being fixed in a mould, so that the tooth socket cannot be molded; the excessive thickness can increase the pressure between the conductive silicone and the gum, which can cause discomfort and even injury to the user during the process of wearing the mouthpiece.

Under the existing scheme, due to the fact that the conductive copper sheet is coated by the conductive silica gel, the wall thickness of the tooth socket is too thick due to the layer-by-layer wrapping structure that the conductive silica gel is coated by the insulating silica gel, and the tooth socket cannot be worn. Therefore, in the existing scheme, the conductive silica gel 1 and the conductive copper sheet in the tooth socket are tightly attached to each other in a plane-to-plane manner, and the conductive copper sheet and the conductive silica gel are tightly attached to each other by utilizing the bonding force between the outer layer of insulating silica gel and the outer layer of insulating silica gel to ensure the reliability of electric conduction.

However, the conductive silica gel and the copper sheet are separated from each other along with the deformation of the conductive silica gel and the deformation of the copper sheet on the tooth socket in the wearing process, and the reliable conduction cannot be continued. In order to make the conductive silica gel and the copper sheet reliably contact, the conductive silica gel and the copper sheet must be in close contact at any moment, for example, the conductive silica gel tightly wraps the copper sheet, and the scheme is not feasible in consideration of wearing comfort and the like.

Therefore, the function and the comfort of the tooth socket are comprehensively considered, and the novel design can improve the use comfort as much as possible on the premise of ensuring the functions of the product.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problem that the prior art cannot ensure the conductive reliability and the wearing comfort, and provides a tooth socket for transmitting current, which can improve the reliability and the comfort of the tooth socket simultaneously. Ensuring that the part of the tooth socket which is expected to be contacted with a user can stably output current, and the rest part is insulated; on the other hand, the utility model can reduce the compression of the tooth socket on the gum and improve the comfort level.

In order to achieve the purpose, the utility model provides a tooth socket for transmitting current, which comprises a plurality of pieces of conductive silica gel for transmitting current to gum, a flexible circuit board for connecting each piece of conductive silica gel and a power supply, and insulating silica gel forming a tooth socket body and partially wrapping the flexible circuit board and the conductive silica gel, wherein the conductive silica gel is exposed from the top of the insulating silica gel to the gum.

Wherein, the exposed part of the conductive silica gel is insulated from the part of the gum which is not contacted with the gum by spraying an insulating coating.

Preferably, the surface of the conductive silica gel, which is not in contact with the gum, is provided with an insulating coating, and the surface in contact with the gum is correspondingly communicated with the contact points on the corresponding flexible circuit board.

Further, the insulating coating has good biocompatibility and is baked at high temperature. The area where the flexible circuit board is connected with the conductive silicone rubber needs to have at least two holes for connecting with the conductive silicone rubber. The conductive silica gel at the embedded connection part of the conductive silica gel and the flexible circuit board is thicker, and the region of the insulating silica gel coated with the conductive silica gel is thinner. The position of the flexible circuit board is arranged at the occlusion part of the tooth socket.

In the present invention, the position of the flexible circuit board is concentrated at the bite, so that the thickness of the partial mouthpiece is thickened without thickening the thickness of the portion between the gum and the lip to ensure the wearing comfort. On the other hand, the conductive silica gel is changed from exposing a strip facing to the gum to exposing a whole slice, the conductive performance of the slice is kept on the surface contacting with the gum, and the other surfaces not contacting with the gum are insulated by adjusting a mould or spraying an insulating coating. Therefore, the contact area of the conductive part and the gum is increased, the pressure of the tooth socket on the gum is reduced, and the uniformity of current transmission is enhanced. On the other hand, the parts which do not need to be conducted are shielded by the insulating layer, so that the safety of the tooth socket in the oral cavity of the user can be ensured.

The utility model improves the use comfort as much as possible on the premise of ensuring the functions of the product. The electric conduction reliability of the tooth socket is improved, and the possibility of disconnection of the electric conduction part can be avoided after long-term use; on the other hand, the wearing comfort level of the tooth socket is increased by reducing the pressure of the conductive silica gel and the gum, and meanwhile, the safety of the tooth socket is ensured by shielding the unexpected conductive part.

The present invention is described in further detail below to enable those skilled in the art to practice the utility model with reference to the description.

The solution of the utility model is to change the structure of the tooth socket into a scheme of reliably coating the conductive silica gel on the flexible circuit board and coating the insulating silica gel on the conductive silica gel and the flexible circuit board. In addition, under the scheme, the flexible circuit board is arranged at the occlusion part, so that the thickness of the local tooth socket is thickened, the thickness of the part between the gum and the lip is not thickened, and the wearing comfort is ensured.

On the other hand, the parts which do not need to be conducted are shielded by the insulating layer, so that the safety of the tooth socket in the oral cavity of the user can be ensured.

The following is a specific embodiment of the present invention.

Referring first to fig. 2, fig. 2 is a diagram illustrating a finished dental mouthpiece according to an embodiment of the present invention. As shown in figure 2, the mouthpiece according to one embodiment of the present invention comprises a mouthpiece body having inner and outer sidewalls parallel to teeth for wrapping the teeth and gums; intermediate the two side walls there is a bite portion 12. The upper and lower tip of two inside and outside lateral walls of facing teeth cover body has the protruding electrically conductive silica gel 11 of a plurality of, and electrically conductive silica gel 11 is towards one side and the gum contact of gum, to gum transmission current.

Referring to fig. 3, fig. 3 is a diagram illustrating a conductive silicone rubber and a flexible circuit board being embedded according to an embodiment of the present invention. The flexible circuit board 21 includes the required circuits, which are used to connect the conductive silicone rubbers 11 to an external power supply or control circuit in this embodiment. The area connected to the conductive silicone gel 11 needs to have at least two holes for more stable connection with the conductive silicone gel. And the insulating silica gel forming the tooth socket body and partially wrapping the flexible circuit board 21 and the conductive silica gel 11, wherein the conductive silica gel 11 is exposed from the top of the insulating silica gel 31 to face the gum. And placing the flexible circuit board 21 in a conductive silica gel 11 mould, injecting the conductive silica gel 11 into the mould to be embedded and molded with the flexible circuit board 21, and forming the embedded flat plate 2 of the flexible circuit board 21 and the conductive silica gel 11.

One surface of the embedded flat plate 2 is coated with an insulating coating with good biocompatibility and then baked at high temperature to ensure that the coating is tightly connected with one surface of the conductive silica gel 11. The performance of the embedded flat plate 2 can be checked by checking the electrical impedance between the circuit contact and the two surfaces of the conductive silica gel 11.

Referring to fig. 4, fig. 4 is a partial cross-sectional view illustrating an embodiment of the utility model. The insulating silicone rubber 31 covers the conductive silicone rubber 11 and the flexible circuit board 21. After the conductive silica gel 11 is coated on the flexible circuit board 21, the conductive silica gel and the insulating silica gel 31 are coated on the flexible circuit board and finally formed. Note that the conductive silicone gel 11 at the portion where the conductive silicone gel 11 is connected to the flexible circuit board 21 by fitting is thick, because the silicone gel molded on the flexible circuit board 21 requires a sufficient thickness to ensure the reliability of molding due to the requirement of molding the silicone gel. Since the bonding force between the silicone gel and the silicone gel is large, the region of the insulating silicone gel 31 covering the conductive silicone gel 11 may be relatively thin. Furthermore, the bite area is less stressed by the lips and gums, so that thickening of this area does not have any effect on the comfort of the user.

The embedded flat plate 2 is placed into a matched tooth socket final forming mold in the mode, the finally exposed conductive silica gel 11 is ensured to be tightly attached to the inner cavity of the mold, and then the mold is closed and locked. The insulating silica gel 31 is injected into the mould by a high-pressure injection mode and then is vulcanized and molded at high temperature.

Since the human lingual gingiva is considered to be flattened from the vertical direction to the inward direction, the lingual conductive silicone gel 11 is pressed and deformed by the lingual upper jaw and the lingual lower jaw to ensure the conformity with the lingual gingiva. Considering the lip side gum, the lip will attach the conductive silicone gel 11 to the lip side gum due to the lip. Before the final forming, the periphery of the conductive silica gel 11 is insulated by the coating, the gum side is kept in good conductivity, and the rest part is insulated by the insulating silica gel 31, so that the safety and the effectiveness of the finally formed tooth socket can be guaranteed.

Finally, the newly produced tooth socket is tested by the implementation, the gum ulcer rate of the user is reduced by 87.5% (8/30 is changed into 1/30), and the electric conduction effectiveness of the tooth socket is still 100% after continuous testing for 300 days, which is far superior to about 75% of the prior art. Therefore, the utility model can effectively improve the safety, effectiveness and comfort of the tooth socket.
