Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to an oral care device. Background Art

[0002] Oral care includes daily oral cleaning, such as brushing, rinsing, and using an oral irrigator; it also includes regular checkups and professional care, such as teeth cleaning and dental examinations. In oral care, in order to more conveniently observe the oral cavity and perform care, an oral retractor is usually used. The oral retractor is usually used for patients who have difficulty opening their mouths due to oral muscle tension or for younger children.

[0003] In the document with announcement number CN115517619A, a dental examination and care device is disclosed, which includes a support frame, a first support frame, a rack and a spur gear. There are at least two support frames, which are connected to both sides of the first support frame. Both sides of the support frame are connected to the rack in a sliding manner. The middle part of the first support frame is rotatably fixed with a spur gear. In this device, it can open the patient's lips and press down the tongue, thereby facilitating the doctor's examination.

[0004] However, in the above patent, the stretching block relies on a screw slider structure to stretch the lips horizontally, which has the following problems: first, each stretching block needs to be adjusted individually, which is inefficient; second, the scope of application of this device is narrow, and its stretching block can only move in one direction.

[0005] Therefore, in view of the above problems, it is necessary to study an oral care device that is more convenient to use and more convenient for doctors to perform care. Summary of the Invention

[0006] The present invention discloses an oral care device, which aims to solve the technical problems that the existing devices are difficult to adjust and have a single direction, making it inconvenient for doctors to perform care.

[0007] In order to solve the above-mentioned technical problems, the technical solutions adopted by the present invention are as follows:

[0008] An oral care device includes a support block, a transverse support assembly and a longitudinal support assembly.

[0009] The lateral support assembly includes a lateral adjustment assembly and a rotation assembly. The lateral adjustment assembly includes a gear and two racks respectively meshing with the upper and lower sides of the gear. The opposite ends of the two racks are connected to lateral support blocks. The rotation assembly is connected to the gear.

[0010] The longitudinal support assembly is provided on the upper side and / or the lower side of the support block.

[0011] After adopting this technical method, the support block is placed in the patient's mouth during use. There is an inspection port in the center of the support block for the doctor to perform examination and care. In order to adapt to patients of different age groups, the device expands the patient's mouth laterally by setting a transverse support component, and expands the patient's mouth longitudinally by using a longitudinal support component to meet the needs of oral care and inspection. In addition, the gear rack structure is used as a transmission mechanism, and the two racks are moved in opposite directions by rotating the rotating component, so that the transverse support block moves accordingly to support the patient's mouth in the transverse direction, while the longitudinal support component is limited at its appropriate height by the longitudinal limiter to provide longitudinal support. The two cooperate to achieve rapid support of the oral cavity and improve care efficiency.

[0012] In addition, the lateral support block is made of rubber, which makes the patient more comfortable during the nursing process, and is covered with absorbent cotton to absorb the secreted saliva;

[0013] Finally, it should be noted that both sides of one end of the support block located in the oral cavity are open, and the transverse support block is located at the opening. When the transverse support block is in the initial state, the transverse support block and the opening are integrated into one.

[0014] Furthermore, an adjustment cavity is provided transversely through the upper wall or lower wall of the support block, a sliding member is provided in the adjustment cavity for sliding along the depth direction, the two racks are respectively slidably provided on the upper and lower inner walls of the sliding member, and the rotating assembly penetrates into the sliding member and is connected to the gear.

[0015] After adopting this technical method, in order to enable the lateral support component of the device to adjust the depth and improve the applicability of the device, an adjustment cavity is set. When depth adjustment is required, the sliding part can be moved in the adjustment cavity by adjusting the rotating component, thereby driving the lateral support block to adjust the depth to adapt to patients of different age groups and enable doctors to provide better care and examination.

[0016] In addition, it should be noted that a sliding groove is provided along the depth direction on the bottom surface of the adjustment cavity, and a limit piece is provided on the bottom surface of the sliding part that cooperates with the sliding groove. The limit piece slides in cooperation with the sliding groove, and the sliding part is a square tube structure that fits the adjustment cavity. The openings at both ends of the sliding part facilitate the outward extension of the rack, and a through hole is opened on the side of the sliding part close to the rotating component for the rotating component to pass through.

[0017] Furthermore, a third limiting hole and a fourth limiting hole that are interconnected are longitudinally provided in the upper wall or the lower wall of the support block, one end of the third limiting hole is connected to the outside world, and one end of the fourth limiting hole is connected to the adjusting chamber, and the rotating component is movably arranged in the third limiting hole and the fourth limiting hole, one end of the rotating component extends to the outside world, and the other end is connected to the gear.

[0018] After adopting this technical solution, it should be noted that a method for adjusting the depth of the lateral adjustment assembly is provided here, that is, applying pressure inward or pulling outward on the rotating assembly will cause the rotating assembly to move in the depth direction, thereby driving the sliding member to move accordingly, and the rack in the sliding member is connected to the lateral support block, thereby achieving the depth adjustment of the lateral support block;

[0019] In this method, the inner diameter of the third limiting hole is larger than the inner diameter of the fourth limiting hole, and the shape of the rotating component fits the diameter settings of the third limiting hole and the fourth limiting hole. During the process of continuously applying pressure inward to the rotating component, when the part with a larger diameter of the rotating component moves to the fourth limiting hole, it will restrict further inward movement, thereby improving safety in use.

[0020] Preferably, the rotating assembly includes a first rotating rod, a telescopic sleeve and a second rotating rod, one end of the telescopic sleeve is arranged inside the first rotating rod, and the outer wall of the telescopic sleeve is threadedly connected to the inner wall of the first rotating rod, the other end of the telescopic sleeve is sleeved with the second rotating rod, the second rotating rod is connected to the first rotating rod, and the second rotating rod is connected to the gear.

[0021] The first rotating rod and the second rotating rod are respectively provided with a first annular limit block and a second limit block, the telescopic sleeve is provided with a limit strip along the axial direction of the telescopic sleeve, the third limit hole, the fourth limit hole and the inner wall of the telescopic sleeve are respectively provided with a first annular groove, a limit groove and a second annular groove, the first limit block, the limit strip and the second limit block respectively cooperate with the first annular groove, the limit groove and the second annular groove.

[0022] This solution provides another more precise way to adjust the depth and lateral support simultaneously, making it easier to use in younger patients and reducing the length of the rotating component exposed to the outside.

[0023] First of all, it should be explained that the first rotating rod is provided with an annular limit groove along the axial direction, and the telescopic sleeve is annular, which is inserted into the first rotating rod through the annular limit groove, and one end of the annular limit groove is provided with a thread that cooperates with the first rotating rod. The second rotating rod is fixedly connected with the first rotating rod after passing through the telescopic sleeve; in this scheme, when making adjustments, it is only necessary to rotate the first rotating rod, and the telescopic sleeve will extend, thereby pushing the sliding part to move and perform lateral adjustments simultaneously. Specifically, since an axial limit strip is provided on the telescopic sleeve, and a limit groove is provided along the axial direction of the fourth limit hole on the inner wall of the fourth limit hole, the telescopic sleeve can only move along the axial direction of the fourth limit hole and cannot rotate. In addition, an annular first limit block is provided on the first rotating rod, and an annular groove is provided on the side wall of the third limit hole. The cooperation of the annular first limit block will limit the axial movement of the first rotating rod along the third limit hole. Finally, the connection structure between the second rotating rod and the telescopic sleeve is consistent with the connection structure between the first rotating rod and the third limit hole. Through this connection, when the first rotating rod is rotated, the second rotating rod can follow the rotation, causing the gear to rotate and at the same time follow the telescopic sleeve to telescope. Therefore, under the above-mentioned restriction conditions and the threaded connection conditions of the first rotating rod and the telescopic sleeve, when the first rotating rod is rotated, the telescopic sleeve will extend inward compared to the first rotating rod, thereby pushing the second sliding member to slide, realizing precise depth adjustment of the lateral support block, and at the same time making the lateral support block expand outward, realizing synchronous adjustment of depth and lateral expansion according to the patient's age, enhancing patient comfort, and greatly reducing the outward extension length of the first rotating rod.

[0024] Preferably, a first limiting hole and a second limiting hole that are interconnected are provided on both sides of the upper surface and / or lower surface of the support block, and a support rod is provided on one side of the longitudinal support assembly close to the support block, and the support rod corresponds to the first limiting hole, and the support rod passes through the first limiting hole and enters the second limiting hole, and a first elastic member is provided between the support rod and the bottom surface of the second limiting hole.

[0025] This solution provides a longitudinal support method. Specifically, the elastic force generated by the first elastic member enables the longitudinal support component to support the patient's mouth. This solution is used for older patients, and the elastic force of the first elastic member provides stable support for the longitudinal support component.

[0026] Preferably, a longitudinal limiting assembly is further provided in the second limiting hole, and the longitudinal limiting assembly includes a limiting rod and a slider, the slider is slidably arranged in the second limiting hole, the support rod is connected to the slider, and the first elastic member is provided between the lower end of the slider and the bottom surface of the second limiting hole, and a threaded hole is penetrated by the slider, one end of the limiting rod is threadedly connected to the threaded hole, and the other end of the limiting rod penetrates the side wall of the second limiting hole and extends outward.

[0027] This solution provides another more accurate way of providing longitudinal support, so that it can be used in younger patients. First of all, it should be noted that in this solution, only the longitudinal support assembly on one side can be adjusted, and longitudinal support is provided by longitudinal movement of the longitudinal support assembly on the upper or lower side of the support block; specifically, it also relies on the elastic force of the first elastic member to enable the longitudinal support assembly to support the oral cavity, but in this device, considering that the oral mucosa of younger patients is fragile, a longitudinal limit assembly is provided to limit the support height. In actual use, the movement of the slider can be adjusted by toggling the limit rod, thereby driving the longitudinal support assembly to be adjusted. After the position is appropriate, tighten the limit rod so that the limit rod is pressed against the side wall of the second limit hole to achieve limitation.

[0028] In addition, it should be noted that a long hole corresponding to the position of the second limiting hole is provided on the front end surface of the support block, the long hole is connected to the second limiting hole, and the limiting rod passes through the long hole and extends outward.

[0029] Preferably, the longitudinal support assembly adopts a soft support assembly or a dental tray, and the soft support assembly includes a support plate and an air bag, and the air bag is arranged on a side of the support plate away from the support block.

[0030] The dental tray comprises an upper dental tray and a lower dental tray, and care components are arranged in the upper dental tray and the lower dental tray.

[0031] This solution provides two longitudinal support component structures, each suitable for patients of different age groups. When using the soft support component, the support rod is set on the support plate, and the contact between the airbag and the skin reduces damage to the oral mucosa. In addition, it should be noted that the airbag adopts an arc-shaped structure, and its arc surface fits the arc surface of the oral cavity to improve user comfort.

[0032] When the patient needs oral care, such as gum massage and teeth care, oral care can be performed through the upper and lower dental trays.

[0033] Furthermore, the nursing component includes a driving motor, a nursing plate, a follower plate and a cam.

[0034] A tooth socket is provided at the upper end of the upper dental tray, cavities are provided on both sides of the tooth socket, the cavities are connected to the tooth socket through through holes, the two cavities are provided with the follower plate, the care plate is provided on the side of the tooth socket, a connecting block is provided on the follower plate, the connecting block passes through the through hole and is connected to the care plate, the cam is provided between the lower end of the follower plate and the bottom surface of the cavity, and the cam is connected to the output shaft of the drive motor.

[0035] First of all, it should be noted that the structures of the upper and lower dental trays are the same. The description in this application takes the upper dental tray as an example. However, when the longitudinal limit assembly is adopted, only one side of the dental tray is provided with a support rod. In this solution, the cam mechanism drives the follower plate to reciprocate up and down, and the follower plate drives the care plate to reciprocate up and down, thereby achieving gum or tooth care. Specifically, when the drive motor rotates, it drives the cam to rotate, and the cam drives the follower plate to reciprocate up and down, thereby driving the care plate to move;

[0036] In addition, it should be noted that the tooth socket and the care plate are both in an arc shape that fits the arrangement of teeth. When caring for patients with teeth, just place the teeth in the tooth socket.

[0037] Furthermore, positioning holes are provided at both ends of the follower plate, positioning columns are longitudinally provided at both ends of the two cavities, the positioning columns pass through the positioning holes, and a second elastic member is provided between the lower end of the follower plate and the bottom surface of the cavity.

[0038] It should be noted that the elastic force of the second elastic member ensures that the lower surface of the follower plate is always in contact with the cam surface. Specifically, when the follower plate is in the lowest position, the second elastic member is still in a stretched state, which provides a downward pulling force to make the follower plate contact with the cam. Therefore, no matter how the cam rotates, the lower surface of the follower plate will always be in contact with the cam surface, so that the nursing plate produces a stable reciprocating motion.

[0039] A control chamber is further provided inside the upper dental tray, wherein a battery, a control board and the motor are provided in the control chamber, the motor is electrically connected to the battery and the control board respectively, and the control board is electrically connected to the battery.

[0040] The support block is further provided with a control knob, and the control knob is electrically connected to the control board.

[0041] It should be noted that after adopting this solution, the battery is a rechargeable battery, which is connected to the power supply through an external interface. Specifically, an opening is provided on the side of the upper dental tray and a sealing plug is provided in the opening, and the charging interface is provided in the opening; the speed of the motor is adjusted by turning the control knob to achieve adjustable care intensity.

[0042] Preferably, a care piece is provided on the side of the care plate, and the care piece may be a massage ball, a care brush, etc.

[0043] Preferably, connecting ears are provided on both sides of the front end surface of the support block, and fixing belts are connected to the connecting ears. The fixing belts are connected by Velcro to achieve wearing and fixing of the device.

[0044] The use steps of the present invention are:

[0045] Wearing: Wear the device on the patient's head through the fixing strap and Velcro, and put the support block into the patient's mouth to complete the wearing and fixing;

[0046] Adjustment of the lateral support assembly: In one embodiment, the position of the slider is adjusted by directly pulling or pressing the first rotating rod, thereby changing the depth of the lateral support block, and then rotating the first rotating rod to adjust the expansion of the lateral support block;

[0047] In another solution, the first rotating rod is rotated to move the telescopic sleeve inward, thereby driving the second rotating rod, the sliding member, and the gear rack set in the sliding member to move inward in turn. The movement of the rack drives the lateral support block to move inward to achieve depth adjustment. At the same time, the rotation of the first rotating rod drives the second rotating rod to rotate, thereby driving the gear to rotate to achieve expansion of the lateral support block.

[0048] Adjustment of the longitudinal support assembly: Move the limit rod to adjust the movement of the slider, thereby driving the longitudinal support assembly to adjust. After the position is appropriate, tighten the limit rod so that the limit rod is pressed against the side wall of the second limit hole to achieve limit.

[0049] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0050] 1. The oral care device provided by the present invention utilizes a rack and pinion structure as a transmission mechanism. Rotating a rotating assembly causes the lateral support block to move accordingly. The longitudinal support assembly is positioned at an appropriate height by a longitudinal stopper, thereby providing longitudinal support. The two components work together to rapidly support the oral cavity and improve care efficiency.

[0051] 2. The present invention provides an oral care device, which is configured by setting a first rotating rod, a telescopic sleeve and a second rotating rod, so that the telescopic sleeve and the first rotating rod are threadedly connected, and the axial movement of the first rotating rod and the rotation of the telescopic sleeve are restricted, and the second rotating rod is respectively connected to the first rotating rod and the telescopic sleeve for rotation, so that when the first rotating rod is rotated, the lateral support block can be synchronously adjusted in depth and expanded in the lateral direction, and is suitable for children of different ages.

[0052] 3. The present invention provides an oral care device, in which the longitudinal support component is softly supported by an airbag, and the airbag adopts an arc-shaped structure, and its arc surface is configured to fit the arc surface of the oral cavity to improve user comfort and reduce damage to the oral mucosa.

[0053] 4. The present invention provides an oral care device, which provides a cam mechanism in the dental tray, and relies on the cam mechanism to drive the follower plate to perform up and down reciprocating motion, and the follower plate drives the care plate to perform up and down reciprocating motion, thereby achieving care for gums or teeth.

[0071] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0072] Example 1

[0073] An oral care device, such as Figures 1-4 、 Figure 7 As shown, it includes a support block 1, a transverse support assembly and a longitudinal support assembly.

[0074] The lateral support assembly includes a lateral adjustment assembly 12 and a rotating assembly 2. The lateral adjustment assembly 12 includes a gear 1202 and two racks 1201 respectively meshing with the upper and lower sides of the gear 1202. The two opposite ends of the two racks 1201 are connected to the lateral support block 4. The rotating assembly 2 is connected to the gear 1202.

[0075] The longitudinal support components are provided on both the upper and lower sides of the support block 1 .

[0076] Both sides of the upper surface and the lower surface of the support block 1 are provided with a first limiting hole 102 and a second limiting hole 103 that are interconnected. A support rod 502 is provided on one side of the longitudinal support assembly close to the support block 1. The support rod 502 corresponds to the first limiting hole 102. The support rod 502 passes through the first limiting hole 102 and penetrates into the second limiting hole 103. A first elastic member 303 is provided between the support rod 502 and the bottom surface of the second limiting hole 103.

[0077] The longitudinal support assembly adopts a soft support assembly, which includes a support plate 8 and an airbag 9. The airbag 9 is arranged on a side of the support plate 8 away from the support block 1.

[0078] The support block 1 is provided with connecting ears 10 on both sides of the front end surface. The connecting ears 10 are connected to fixing belts 7. The fixing belts 7 are connected by Velcro to achieve wearing and fixing of the device.

[0079] The transverse support block 4 is made of rubber material, which makes the patient more comfortable during the nursing process. The transverse support block 4 is covered with absorbent cotton to absorb the secreted saliva. The support block 1 is located in the oral cavity and has openings on both sides. The transverse support block 4 is located at the opening. When the transverse support block 4 is in the initial state, the transverse support block 4 and the opening are combined into one.

[0080] In this embodiment, the gear 1202 and rack 1201 structure are used as a transmission mechanism, and the two racks 1201 are moved in opposite directions by rotating the rotating component 2, so that the transverse support block 4 moves accordingly, and the patient's mouth is supported in the transverse direction, while the longitudinal support component is limited at its appropriate height by the longitudinal limit member, thereby providing longitudinal support. The two cooperate to achieve rapid support for the oral cavity and improve nursing efficiency. In this embodiment, the elastic force generated by the first elastic member 303 enables the longitudinal support component to support the patient's mouth. This solution is used for patients in older age groups, and the elastic force of the first elastic member 303 provides stable support for the longitudinal support component.

[0081] Example 2

[0082] The difference between this embodiment and embodiment 1 is that Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 As shown, an adjustment cavity 101 is provided transversely through the upper wall or the lower wall of the support block 1, and a sliding member is provided in the adjustment cavity 101 to slide along the depth direction. The two racks 1201 are respectively slidably provided on the upper and lower inner walls of the sliding member, and the rotating component 2 penetrates into the sliding member and is connected to the gear 1202.

[0083] A third limiting hole 104 and a fourth limiting hole 106 that are interconnected are longitudinally provided in the upper wall or the lower wall of the support block 1. One end of the third limiting hole 104 is connected to the outside world, and one end of the fourth limiting hole 106 is connected to the adjusting chamber 101. The rotating component 2 is movably arranged in the third limiting hole 104 and the fourth limiting hole 106. One end of the rotating component 2 extends to the outside world, and the other end is connected to the gear 1202.

[0084] In this embodiment, a sliding groove is provided along the depth direction on the bottom surface of the adjustment cavity 101, and a limit piece cooperating with the sliding groove is provided on the bottom surface of the sliding member. The limit piece slides with the sliding groove, and the sliding member is a square tube structure that fits the adjustment cavity 101. The openings at both ends of the sliding member facilitate the outward extension of the rack 1201. A through hole 505 is provided on the side of the sliding member close to the rotating component 2 for the rotating component 2 to pass through.

[0085] In this embodiment, a method for adjusting the depth of the lateral adjustment assembly 12 is provided. That is, by applying pressure inward or pulling outward on the rotating assembly 2, the rotating assembly 2 will move in the depth direction, thereby driving the sliding member to move accordingly. The rack 1201 in the sliding member is connected to the lateral support block 4, thereby achieving depth adjustment of the lateral support block 4.

[0086] In this embodiment, the inner diameter of the third limiting hole 104 is larger than the inner diameter of the fourth limiting hole 106, and the shape of the rotating component 2 fits the diameter settings of the third limiting hole 104 and the fourth limiting hole 106. During the process of continuously applying pressure inward to the rotating component 2, when the part with a larger diameter of the rotating component 2 moves to the fourth limiting hole 106, it will restrict further inward movement, thereby improving safety of use.

[0087] Example 3

[0088] The difference between this embodiment and embodiment 2 is that Figure 4 、 Figure 5 As shown, the rotating assembly 2 includes a first rotating rod 201, a telescopic sleeve 202 and a second rotating rod 203. One end of the telescopic sleeve 202 is arranged inside the first rotating rod 201, and the outer wall of the telescopic sleeve 202 is threadedly connected to the inner wall of the first rotating rod 201. The other end of the telescopic sleeve 202 is sleeved with the second rotating rod 203, and the second rotating rod 203 is connected to the first rotating rod 201. The second rotating rod 203 is connected to the gear 1202.

[0089] The first rotating rod 201 and the second rotating rod 203 are respectively provided with a first annular limit block 205 and a second limit block 206. The telescopic sleeve 202 is provided with a limit strip 204 along the axial direction of the telescopic sleeve 202. The third limit hole 104, the fourth limit hole 106 and the inner wall of the telescopic sleeve 202 are respectively provided with a first annular groove 105, a limit groove 107 and a second annular groove. The first limit block 205, the limit strip 204 and the second limit block 206 cooperate with the first annular groove 105, the limit groove 107 and the second annular groove.

[0090] This embodiment provides another more precise synchronous adjustment method for the depth and lateral support, so as to facilitate use in patients of younger ages and reduce the length of the rotating assembly 2 exposed to the outside. Specifically, the first rotating rod 201 is provided with an annular limiting groove 107 along the axial direction, and the telescopic sleeve 202 is annular and is inserted into the first rotating rod 201 through the annular limiting groove 107. One end of the annular limiting groove 107 is provided with a thread that cooperates with the first rotating rod 201. After the second rotating rod 203 penetrates the interior of the telescopic sleeve 202, it is connected to the first rotating rod 201. The rotating rod 201 is fixedly connected; in this solution, when making adjustments, it is only necessary to rotate the first rotating rod 201, and the telescopic sleeve 202 will extend, thereby pushing the sliding member to move and synchronously making lateral adjustments. Specifically, since the telescopic sleeve 202 is provided with an axial limit strip 204, and the inner wall of the fourth limit hole 106 is provided with a limit groove 107 along the axial direction of the fourth limit hole 106, the telescopic sleeve 202 can only move along the axial direction of the fourth limit hole 106 and cannot rotate. In addition, the first rotating rod 201 An annular first limiting block 205 is provided on the upper portion, and an annular groove is provided on the side wall of the third limiting hole 104. The annular groove cooperates with the annular first limiting block 205 to limit the axial movement of the first rotating rod 201 along the third limiting hole 104. Finally, the connection structure between the second rotating rod 203 and the telescopic sleeve 202 is consistent with the connection structure between the first rotating rod 201 and the third limiting hole 104. Through this connection, when the first rotating rod 201 is rotated, the second rotating rod 203 can follow the rotation, causing the gear 1202 to rotate, and at the same time can follow the telescopic sleeve 20 2 is telescopic, so under the above-mentioned restrictions and the condition of the threaded connection between the first rotating rod 201 and the telescopic sleeve 202, when the first rotating rod 201 is rotated, the telescopic sleeve 202 will extend inward compared to the first rotating rod 201, thereby pushing the second sliding member to slide, achieving precise depth adjustment of the lateral support block 4, and at the same time causing the lateral support block 4 to expand outward, realizing synchronous adjustment of the depth and lateral expansion according to the age of the patient, enhancing the patient's comfort, and significantly reducing the outward extension length of the first rotating rod 201.
