For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, it will be understood by those of ordinary skill in the art that in various embodiments of the present application, numerous specific details are set forth in order to provide a thorough understanding of the present application. The claimed application may be practiced without these specific details and with various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not be construed as limiting the specific implementation of the present application, and the embodiments can be mutually combined and referred to without contradiction.

For the sake of simplicity of the drawing, the parts relevant to the present utility model are shown only schematically in the figures, which do not represent the actual structure thereof as a product. Additionally, in order to simplify the drawing for ease of understanding, components having the same structure or function in some of the drawings are shown schematically with only one of them, or only one of them is labeled. Herein, "a" means not only "only this one" but also "more than one" case.

As known from the background technology, for the oral vestibule shield of the external force measuring device, because the opening part of the external force measuring device is adjacent to the vestibule shield, the lips of the patient are easy to contact with the external force measuring device at the opening part when the external force measuring device is worn, so that the lips are easy to touch to cause the injury of the lips when the external force measuring device is worn, and even the force measurement of the traction force measuring device can be possibly influenced.

Based on the above, the utility model provides an oral cavity muscle function appliance, which comprises an arc-shaped plate, a traction piece and a separation piece, wherein the arc-shaped plate is matched with an oral cavity vestibule and can be worn between human dentition and labial muscles or labial cheek muscles; the traction piece is provided with an opening part for externally hanging the force measuring device; the isolating piece is arranged between the arc-shaped top end of the arc-shaped plate and the traction piece, one end of the isolating piece is connected with the arc-shaped top end, and the other end of the isolating piece is connected with the traction piece; the opening portion includes a rear end adjacent to the spacer and a front end remote from the spacer; when the device is worn, the limiting edge of the lip of the patient, which is covered along the far tooth direction, is positioned between the rear end of the opening part and the arc-shaped top end of the arc-shaped plate.

The details of the implementation of the oral muscle function appliance according to the present application will be specifically described below with reference to specific embodiments, and the following description is provided only for convenience of understanding, and is not necessary to implement the present embodiment.

An embodiment of the present utility model provides an oral muscle function appliance, as shown in fig. 2-6, comprising: an arc plate 20 adapted to the vestibule of the oral cavity, in this embodiment, the arc plate 20 may be made of a liquid silica gel material, the arc plate 20 has a smooth outer edge, a groove 201 for avoiding the oral cavity labial ligament is arranged in the middle of the arc plate 20, preferably, two grooves 201 for avoiding the oral cavity labial ligament are symmetrically arranged on the upper and lower sides of the middle of the arc plate 20, the curvature of the arc plate 20 is matched with the oral structure of the human body, so that the arc plate 20 may be worn between the dentition of the human body and the labial muscle or the labial cheek muscle to block the dental jaw and the labial cheek muscle, and of course, in actual use, the shape of the arc plate 20 and the contact condition between the arc plate and each part in the oral cavity may be determined according to the specific situation and needs of the case, for example, for the type III malocclusion of the arc plate 20, the cross-sectional shape of the arc plate 20 may be such that the labial cheek muscle and the upper jaw are blocked, the limiting force of the labial cheek muscle is relieved, the growth of the periosteum is stimulated, the upper jaw continues to grow, and the buccal cheek muscle is able to be able to conduct the growth to the lower jaw; the pulling member 21 is provided with an opening 210 formed through the thickness direction of the pulling member 21, the opening 210 is used for hanging a force measuring device to measure a force value used in pulling training after wearing the appliance, the size of the opening 210 at least meets the hanging requirement of the hanging part of the force measuring device, and the shape of the opening can be unlimited, runway-shaped, circular, or triangular or even polygonal, so long as the hanging requirement of the force measuring device can be met; a spacer 22 having one end connected to the arc-shaped top end of the arc-shaped plate 20, i.e., the middle of the arc-shaped plate 20, and the other end connected to the pulling member 21, the opening 210 of the pulling member 21 having a rear end 210a adjacent to the spacer 22 and a front end 210b remote from the spacer 22; in order to prevent the external force measuring device from contacting with the lips of the patient when the oral muscle function appliance is worn, the limiting edges covered by the lips of the patient along the distal tooth direction should be located between the rear end 210a and the arc-shaped top end, as shown in fig. 6, that is, the limiting edges covered by the upper lip 23 and the lower lip 24 of the patient are all within the range of the spacer 22 when the oral muscle function appliance is worn, that is, the lips of the patient cannot cover the coverage area of the opening when the oral muscle function appliance is worn, so that the external force measuring device is not affected, the traction force of the force measuring device is not affected, and meanwhile, the operation of cleaning and sterilizing the force measuring device is avoided when and/or after each use, so that the oral muscle function appliance is convenient for the patient.

Since the lips of a person have a certain thickness, in order to ensure that the lips of a patient do not cover the area of the opening 210 when the oral cavity myofunctional appliance is worn, the length L of the spacer 22 along the distal direction, as shown in fig. 5, should be at least greater than the thickness of the lips of the patient, and meanwhile, since the pulling force needs to ensure the horizontal direction, the too large length L of the spacer 22 along the distal direction easily causes an angle when pulling force, the length L of the spacer 22 along the distal direction should not be too large, in some embodiments, the length L of the spacer 22 along the distal direction is 1cm to 3cm, and the length L of this range ensures that the lips of the patient do not cover the opening 210 of the pulling member 21 in the distal direction when the oral cavity myofunctional appliance is worn, and does not cause an angle when pulling force by the force measuring device.

To further improve the comfort of the patient, the width of the spacer, i.e. the width W along the horizontal direction of the human body in the wearing state, is not too large or too small, if the width is smaller than the width of the patient's middle incisors (generally, the width of the middle incisors is two middle incisors on the upper and lower dentitions of the human body), the place where the lips are placed is too narrow, the discomfort of the lips of the patient is easily caused by long-term wearing, and if the width is too large beyond the width of the mouth of the patient, the discomfort of the mouth is also caused by long-term wearing, so in some embodiments, the width W of the spacer 22 along the horizontal direction of the human body is at least equal to the width of the middle incisors and is less than or equal to the width of the mouth of the patient in the wearing state; in some preferred embodiments, the width W of the spacer 22 in the horizontal direction is preferably 2cm or more, and preferably 4cm or less.

Further, considering that the thickness of the spacer 22 is too small, the joint position between the spacer 22 and the arc-shaped top end of the arc-shaped plate 20 is too small, so that the firm connection between the spacer 22 and the arc-shaped plate 20 cannot be ensured, and the overall firmness during the pulling action may be affected, and the pulling force may be affected; if the spacer 22 is too thick, the wearing comfort cannot be ensured, and therefore, in some embodiments, in order to achieve both the firmness of the connection between the spacer 22 and the arc 20 and the wearing comfort, the thickness H of the spacer, that is, the height of the spacer 22 along the vertical direction of the human body during wearing, is selected to be greater than or equal to 2mm and less than or equal to 4mm.

In some embodiments, to enhance the comfort of wearing the oral myofunctional appliance of the present utility model, at least the region of the edge of the upper and/or lower surface of the spacer 22 that contacts the lips has a rounded geometry, specifically, the edge regions of the other free sides of the upper and lower surfaces of the spacer 22, particularly the region of the edge that contacts the lips, except for the sides that connect the curved tip and the pulling member 21, are rounded so that the patient's lips do not feel uncomfortable when they contact the edge regions. In some preferred embodiments, in order to make the edges of the free sides of the upper and lower surfaces of the spacer 22 have a smooth geometry, the upper and lower surfaces of the spacer 22 and the adjacent surfaces of the free sides thereof are excessively processed through smoothness, for example, the two ends of the edges of the free sides are connected through smooth arcs, and foreign bodies feel easily due to soft tissue of the oral cavity inner film, edges and burrs, etc., which affect comfort, so that the above structure is formed by adopting a smooth design, thereby improving comfort.

In some embodiments, the upper and/or lower surfaces of the spacer 22 may also be provided with a labial muscle stimulator 221 to stimulate the development of the labial muscle in contact with the lips when worn. In some preferred embodiments, the labial muscle stimulator 221 may be a plurality of small bumps provided on the upper surface and/or the lower surface of the spacer 22, as shown in fig. 7, and when worn, the lips of the patient contact with the bumps to stimulate the development of the labial muscle; in other preferred embodiments, the labial muscle stimulator 221 may also be a plurality of labial spines disposed on the upper surface and/or the lower surface of the separator 22, wherein the labial spines are in the shape of small cylindrical bristles with a diameter of 0.5mm to 1.0mm and a length of 0.5mm to 2.5mm; the specific shape of the labial muscle stimulator is not limited, and any convex structure that can stimulate the labial muscle and is provided on the upper surface and/or the lower surface of the spacer 22 is within the scope of the present utility model.

In some embodiments, to ensure that the spacer 22 connected to the pulling member 21 does not deform to affect the accuracy of the force measurement when the pulling member 21 is pulled by the external force measuring device, the capability of the spacer 22 to resist elastic deformation in the pulling direction should be not less than the capability of the arc 20 to resist elastic deformation in the pulling direction, so that the deformation of the external force measuring device of the pulling member 21 in the pulling direction is less than or equal to the deformation of the arc 20 when the pulling member is pulled by the external force measuring device. In some preferred embodiments, the material of the spacer 22 has a modulus of elasticity greater than or equal to that of the arcuate plate, and the material having a greater modulus of elasticity results in a stiffer spacer 22 that is less deformable when pulled by force measurement; in other preferred embodiments, the spacer 22 and the arc 20 may be made of the same material, for example, liquid silicone materials, but the thickness of the spacer 22 is greater than or equal to that of the arc 20, and the same material but greater thickness also makes the spacer 22 stiffer, so that the spacer is less prone to deformation during force measurement and pulling, and further increases the accuracy during force measurement. In addition, in the present embodiment, the spacer 22 and the pulling member 21 may be integrally formed, that is, the spacer 22 and the pulling member 21 are integrally made of the same material, so that the capability of the spacer 22 to resist elastic deformation in the pulling direction should be not less than the capability of the arc plate 20 to resist elastic deformation in the pulling direction, that is, equal to the capability of the pulling member 21 to resist elastic deformation in the pulling direction should be not less than the capability of the arc plate 20 to resist elastic deformation in the pulling direction; of course, the spacer 22 and the pulling member 21 may not be integrally formed, and the spacer 22 and the pulling member 21 may be connected by a fixed connection or a detachable manner, in which case, in order to ensure accuracy in force measurement, the capability of the pulling member 21 to resist elastic deformation in the pulling direction should not be smaller than the capability of the arc plate 20 to resist elastic deformation in the pulling direction, similarly, the elastic modulus of the material of the pulling member 21 is greater than or equal to that of the arc plate, or the thickness of the pulling member 21 is greater than that of the arc plate, which may also make the capability of the pulling member 21 to resist elastic deformation in the pulling direction not smaller than that of the arc plate 20 to resist elastic deformation in the pulling direction, which will not be repeated herein.

In some embodiments, the spacer 22 and the arc 20 may be integrally connected, for example, made of liquid silicone material, where the thickness of the spacer 22 is at least greater than or equal to the thickness of the arc 20, so that the spacer 22 is less prone to deformation when pulled by force if the capability of resisting elastic deformation of the spacer 22 in the pulling direction is not less than the capability of resisting elastic deformation of the arc 20 in the pulling direction.

In other embodiments, the spacer 22 and the arc 20 may be separate structures, and specifically, the spacer 22 and the arc 20 may be connected to each other by a fixed connection or a detachable connection between the spacer 22 and the arc 20. For the case of the split structure, the spacer 22 may be made of a material with greater rigidity, for example, the spacer 22 may be made of a metal, ceramic or resin material, for example, a plate-shaped structure made of metal, ceramic or resin, and since the metal or ceramic has higher hardness, in order to further improve the comfort of the lip when the oral muscle function appliance of the present utility model is worn in contact with the spacer 22, a slow release layer may be added to the upper surface and/or the lower surface of the spacer 22, and the slow release layer may be an edible gel layer or a silicone layer coated on the upper surface and/or the lower surface of the spacer 22, and the user experience is more comfortable and the comfort is improved when the user uses the softer gel layer or the silicone layer with lower thermal conductivity when the lip of the patient is in contact with the spacer 22.

In this embodiment, the spacer 22 and the arc plate 20 are in a split structure, and the spacer 22 and the arc plate 20 are connected in a detachable connection manner, specifically, a first mounting portion is disposed at an arc top end of the arc plate, a second mounting portion is disposed at a connection end of the spacer, which is connected to the arc top end, and the first mounting portion and the second mounting portion are in a concave-convex matching structure so as to realize detachable connection.

In some embodiments, as shown in fig. 8, the arc-shaped top end of the arc-shaped plate 20 is provided with a first protruding mounting portion 202, the corresponding connecting end of the isolating piece 22 is provided with a second recessed mounting portion 220, the first mounting portion 202 and the second mounting portion 220 are connected through a matching structure, specifically, the first mounting portion 202 may be a screw structure, the second mounting portion 220 may be a threaded hole formed on the isolating piece 22, and when the isolating piece 22 is detachably connected to the arc-shaped plate 20 by screwing a screw on the arc-shaped plate 20 into the threaded hole during installation; of course, the present utility model is not limited to the matching structure of the bolt and the threaded hole, for example, the first mounting portion 202 and the second mounting portion 220 may be detachably connected by a clamping manner, for example, the first mounting portion 202 is a clamping block structure disposed on the arc plate 20, and correspondingly, the second mounting portion 220 is a clamping groove structure disposed on the spacer 22, and during mounting, the detachable connection between the spacer 22 and the arc plate 20 is completed through the cooperation of the clamping block structure and the clamping groove structure. It should be noted that, the detachable connection manner of the first mounting portion and the second mounting portion may also be other connection manners known to those skilled in the art, which is not limited to this embodiment.

In other embodiments, as shown in fig. 9, the arc-shaped top end of the arc-shaped plate 20 is provided with a concave first mounting portion 202, the corresponding connecting end of the isolating member 22 is provided with a convex second mounting portion 220, similarly, the first mounting portion 202 is in a screw structure, and the second mounting portion 220 is a threaded hole formed on the arc-shaped plate 20, and when the isolating member 22 is mounted, the isolating member 22 is detachably connected to the arc-shaped plate 20 by screwing a screw on the isolating member 22 into the threaded hole on the arc-shaped plate 20. In some preferred embodiments, the first mounting portion 202 may be a through hole formed at the arc top end of the arc plate 20, and the through hole penetrating through the arc plate 20 may form an air hole for assisting nasal breathing of a patient when wearing the arc plate 20 without the spacer, so that when only the arc plate without the spacer is required to be worn without traction training, the wearer can breathe through mouth and nose, and the situation that part of the wearer cannot adapt to nasal breathing at early stage, especially when such patient cannot adapt to nasal breathing at night, is easy to cause risk.

In the embodiments of the present application, since the opening 210 needs to be externally hung with a force measuring device to measure force, and when the force is measured, the force needs to be pulled to a side far away from the pulling member 21, at this time, if an undesired movement such as shaking occurs, the measured value of the force measuring device will be affected, and the measured value of the oral muscle strength itself is smaller, so that the accuracy requirement is higher, and the interference in the measuring process needs to be eliminated as much as possible. Therefore, another embodiment of the present application provides an oral muscle training appliance, in this embodiment, the front end 210b of the opening 210 away from the spacer 22 has a force-measuring limiting portion 210c for limiting the hanging position of the force-measuring device when the force-measuring device is hung, in some embodiments, as shown in fig. 10, the force-measuring limiting portion 210c is configured as a circular arc, the maximum width of the force-measuring limiting portion may be less than or equal to 1/3 of the maximum width of the opening 210, for example, the diameter of the force-measuring limiting portion may be 4mm, or may be smaller, so long as the hanging requirement of the hanging portion of the force-measuring device can be met, the circular arc may adapt to a force-measuring device hung in various shapes, and the circular arc is used as the force-measuring limiting portion 210 c. It should be noted that, the shape of the limiting portion is not limited to an arc shape, but may be square, triangular or other shapes in practical application, and more available shapes enable the implementation scheme of the force measuring limiting portion 210c to be more varied, so that the force measuring device can be adapted to various force measuring devices.

It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples of carrying out the application and that various changes in form and details may be made therein without departing from the spirit and scope of the application.
