[0028] refer to Figures 1 to 5 The embodiment of the present application provides a tongue exercise device for head and neck cancer surgery, which may include a bonding sheet 1, a fixing cylinder 2, a piston rod 3, an adjustment component, an adjustment column 4 and a reset component. Both ends of the bonding sheet 1 are provided with straps 11, and the ends of each strap 11 are provided with Velcro; the fixing cylinder 2 is provided on one side of the bonding sheet 1 and its axial direction is the same as the first direction, and the first direction intersects with the bonding sheet 1; the piston rod 3 passes through the bonding sheet 1 and is slidably connected to the bonding sheet 1, and the piston rod 3 has the freedom to slide along its own axial direction and its axial direction is the same as the first direction, and the two ends of the piston rod 3 are divided into Respectively, they are a piston end and a resistance end, the piston end is located in the fixed cylinder 2; the adjusting component is arranged at the end of the fixed cylinder 2 away from the bonding sheet 1 and has a distance between the adjusting component and the fixed cylinder 2, and the adjusting component has the freedom to move along the first direction; the adjusting column 4 is connected to the side of the adjusting component facing the fixed cylinder 2, and the diameter of the adjusting column 4 is larger than the inner diameter of the fixed cylinder 2, wherein the adjusting component drives the adjusting column 4 to move along the first direction in response to the first driving force; the reset component is arranged outside the fixed cylinder 2 and is connected to the adjusting component and the fixed cylinder 2, and the reset component drives the piston rod 3 along the first direction away from the adjusting column 4 in response to the second driving force.

[0029] The present application provides a tongue training device for head and neck cancer surgery. When in use, the side of the adhesive sheet 1 facing away from the fixed tube 2 is placed against the lips. The strap 11 is then passed around the back of the user's head. The two straps 11 are attached with Velcro to fix the adhesive sheet 1 in place. At this time, the contact end of the piston rod 3 contacts the user's tongue, and the tongue pushes the piston rod 3 toward the adjustment column 4. The piston rod 3 is then moved away from the adjustment column 4 by the reset assembly. This reciprocating process can train the tongue with good training effect. At the same time, the adjustment assembly can change the maximum distance between the adjustment column 4 and the fixed tube 2 in the first direction. The diameter of the adjustment column 4 is larger than the inner diameter of the fixed tube 2. As the maximum distance decreases, the outlet for gas escape in the fixed tube 2 becomes smaller, and the resistance encountered by the tongue pushing the piston rod 3 to move increases. In this way, the maximum distance can be adjusted to change the resistance encountered during tongue training. This not only adapts to the training of different people and has a wider range of applications, but also adapts to the training of the same person at different stages, and has a better training effect.

[0030] Specifically, such as Figure 1 As shown, the first direction is the X direction, and the bonding sheet 1 can be arc-shaped, so one side of the bonding sheet 1 is concave and the other side is convex, and the fixing tube 2 is arranged on the convex side of the bonding sheet 1, and the concave side of the bonding sheet 1 fits the user's face better.

[0031] Furthermore, a soft pad can be provided on the concave side of the adhesive sheet 1, so that when the adhesive sheet 1 is fixed to the user's face by the strap 11, the adhesive sheet 1 has less impact on the user's face.

[0032] It should be noted that the maximum distance between the adjusting column 4 and the fixed tube 2 in the first direction refers to the distance between the ends of the adjusting column 4 and the fixed tube 2 that are away from each other; the diameter of the adjusting column 4 is larger than the inner diameter of the fixed tube 2, so that when the adjusting column 4 moves along the first direction to the end of the fixed tube 2 away from the bonding sheet 1, it can completely block the side port of the fixed tube 2.

[0033] It should be understood that the fixed barrel 2 here is similar to the empty barrel of a syringe, and the piston rod 3 is similar to the piston, piston rod and piston handle of a syringe; the piston handle, piston rod and piston of the syringe are sealed and connected to the empty barrel and can slide relative to each other. Similarly, in the present application, the piston rod 3 (equivalent to the combined piston, piston rod and piston handle) is also sealed and connected to the fixed barrel 2 and can slide relative to each other.

[0034] refer to Figure 4In an exemplary embodiment, a sliding groove is provided at the end of the adjusting column 4 away from the fixed cylinder 2, and the depth direction is the same as the first direction; the adjusting assembly may include a limiting cylinder 51, a sealing plate 52, a sliding column 53 and a threaded rod 54, the limiting cylinder 51 is connected to the fixed cylinder 2 and the axial direction is the same as the first direction, wherein one end of the adjusting column 4 is passed through the end of the limiting cylinder 51 close to the fixed cylinder 2, and is slidingly connected to the limiting cylinder 51; the sealing plate 52 is sealingly arranged on the side of the limiting cylinder 51 away from the fixed cylinder 2; the sliding column 53 is passed through the sliding groove and is slidingly connected to the sliding groove, and the sliding column 53 has the freedom to slide along the first direction; the threaded rod 54 passes through the sealing plate 52 and is threadedly connected to the sealing plate 52, the axial direction of the threaded rod 54 is the same as the first direction, and the threaded rod 54 is rotatably connected to the sliding column 53 and has the freedom to rotate around the first direction.

[0035] Specifically, such as Figure 4 As shown, when the threaded rod 54 is rotated, since the threaded rod 54 is threadedly connected to the sealing plate 52, the threaded rod 54 will move along its own axis, that is, the first direction, wherein the force of rotating the threaded rod 54 is the first driving force. In other words, the first driving force is provided by the user.

[0036] When the threaded rod 54 approaches the fixed cylinder 2, the threaded rod 54 will push the sliding column 53 to move synchronously. The sliding column 53 will conflict with the end of the slide groove, and the sliding column 53 will push the adjusting column 4 to move, so that the maximum distance between the adjusting column 4 and the fixed cylinder 2 is reduced, thereby increasing the resistance encountered when pushing the piston rod 3, further increasing the difficulty of training.

[0037] When the threaded rod 54 is away from the fixed cylinder 2, the threaded rod 54 will pull the sliding column 53 to move synchronously, and the sliding column 53 will separate from the end of the slide groove. At this time, when the piston rod 3 is pushed, the gas between the piston rod 3 and the adjusting column 4 will push the adjusting column 4 to move, so that the end of the slide groove will conflict with the sliding column 53, which can increase the maximum distance between the adjusting column 4 and the fixed cylinder 2, thereby reducing the resistance encountered when pushing the piston rod 3, and further reducing the difficulty of training.

[0038] It should be noted that when the threaded rod 54 moves, the threaded rod 54 and the sliding column 53 rotate relative to each other around the first direction, and the sliding column 53 does not rotate; in addition, the end of the slide groove refers to the end of the slide groove away from the slot in its own depth direction.

[0039] Among them, the limiting cylinder 51 is also similar to the empty cylinder of a syringe, and the adjusting column 4 is similar to the piston in a syringe. The piston in the syringe is sealed and connected to the empty cylinder and can slide relative to each other. In this application, the adjusting column 4 is also sealed and connected to the limiting cylinder 51 and can slide relative to each other.

[0040] refer to Figure 2 and Figure 4In an exemplary embodiment, the reset assembly may include a reset airbag, a main line 61, a first branch line 62, a second branch line 63, a first one-way valve 64 and a second one-way valve 65, one end of the main line 61 is connected to the reset airbag; one end of the first branch line 62 is connected to the main line 61, and the other end passes through the sealing plate 52; one end of the second branch line 63 is connected to the main line 61, and the other end passes through the fixed cylinder 2; the first one-way valve 64 is arranged on the second branch line 63; the second one-way valve 65 is arranged on the main line 61, wherein the first branch line 62, the second branch line 63 and the second one-way valve 65 are successively away from the reset airbag on the main line 61.

[0041] Specifically, when the reset airbag is pressed, the gas in the reset airbag first enters the space between the sealing plate 52 and the adjusting column 4, i.e., the first cavity, through the main line 61 and the first branch pipe 62, and pushes the adjusting column 4 to move along the first direction until the adjusting column 4 seals the fixed cylinder 2 away from the end of the bonding sheet 1. At this time, the end of the slide groove on the adjusting column 4 is separated from the sliding column 53, and a closed space is formed between the piston rod 3 and the adjusting column 4. After that, the gas in the reset airbag enters between the adjusting column 4 and the piston rod 3, and pushes the piston rod 3 along the first direction away from the adjusting column 4, so that the piston rod 3 is reset. Among them, the second one-way valve 65 prevents the gas in the reset airbag from leaking out from the end of the main line 61 away from the reset airbag, and the first one-way valve 64 ensures that the gas can enter the fixed cylinder 2 through the second branch pipe 63 to reset the piston rod 3.

[0042] The material of the adjusting column 4 can be rubber material, so that the adjusting column 4 and the end of the empty tube 2 away from the bonding sheet 1 are easily sealed.

[0043] When the reset airbag is reset, it first draws gas from the first cavity, causing the adjustment column 4 to move in the first direction, no longer sealing the end of the fixed tube 2 away from the laminating sheet 1, until the end of the slide groove on the adjustment column 4 contacts the sliding column 53. The reset airbag then draws gas from the end of the main line 61 away from the reset airbag, and this cycle repeats. The second one-way valve 65 ensures that gas can be drawn into the reset airbag from the end of the main line 61 away from the reset airbag, while the first one-way valve 64 prevents gas in the fixed tube 2 from being drawn into the reset airbag.

[0044] Furthermore, the connection area between the main line 61 and the reset airbag can be a hose, so that the reset airbag can be placed in a position that is easy to press when in use, and the force pressing the reset airbag is the second driving force. In other words, the second driving force is provided by the user.

[0045] In an exemplary embodiment, the space between the sealing plate 52 and the adjusting column 4 is a first cavity. When the gas pressure in the first cavity is greater than a, the adjusting column 4 moves along the first direction in response to the pressure in the first cavity and seals the fixed cylinder 2 away from the side of the bonding sheet 1; the first one-way valve 64 is a pressure valve, and the opening pressure of the first one-way valve 64 is b, and b is greater than a.

[0046] Among them, when b is greater than a, the reset airbag is squeezed, and the gas in the reset airbag will preferentially push the adjusting column 4, so that the adjusting column 4 seals and fixes the cylinder 2 away from the side of the bonding sheet 1. At this time, a closed space is formed between the piston rod 3 and the adjusting column 4. After that, the gas pressure rises, and the first one-way valve 64 opens. The gas in the reset airbag enters between the piston rod 3 and the adjusting column 4, thereby pushing the piston rod 3 away from the adjusting column 4, resetting the piston rod 3, and making it easier for the user to push the piston rod 3 next time.

[0047] In an exemplary embodiment, the space between the sealing plate 52 and the regulating column 4 is a first cavity. When the negative pressure of the gas in the first cavity is greater than c, the regulating column 4 moves along the first direction and away from the fixed cylinder 2 in response to the negative pressure in the first cavity; the second one-way valve 65 is a negative pressure valve, and the opening pressure of the second one-way valve 65 is d, and d is greater than c.

[0048] Among them, when d is greater than c, the reset airbag is reset, and negative pressure is formed inside the reset airbag, which will preferentially absorb the gas in the first cavity, so that the end of the slide groove on the adjusting column 4 conflicts with the sliding column 53, and then the negative pressure rises, the second one-way valve 65 opens, and the reset airbag further inhales gas from the end of the main line 61 away from the reset airbag.

[0049] refer to Figure 5 In an exemplary embodiment, the reset airbag may include a base 66, a positioning plate 67, a bellows 68 and a spring 69. The base 66 has a groove 661 at one end, and the main line 61 passes through the outer periphery of the base 66 and is connected to the groove 661; the positioning plate 67 is arranged at the notch of the groove 661, and a plurality of through holes 671 are provided on the positioning plate 67; one end of the bellows 68 is sealedly connected to the positioning plate 67 and the other end is closed, and the connection area between the bellows 68 and the positioning plate 67 covers each through hole 671; the spring 69 is arranged in the bellows 68, one end of the spring 69 is connected to the closed end of the bellows 68, and the other end of the spring 69 is connected to the positioning plate 67.

[0050] Specifically, one end of the bellows 68 is sealed and connected to the positioning plate 67, and the other end is closed, and the connection area between the bellows 68 and the positioning plate 67 covers each through hole 671, so that the gas in the bellows 68 can only enter and exit through the through hole 671; at the same time, the spring 69 is arranged in the bellows 68, one end of the spring 69 is connected to the closed end of the bellows 68, and the other end of the spring 69 is connected to the positioning plate 67. When the bellows 68 is pressed, the gas in the bellows 68 first enters the groove 661 through the through hole 671 and then enters the main line 61. When the hand is released, the spring 69 pushes the bellows 68 to reset, thereby generating negative pressure in the bellows 68 to further inhale gas from the main line 61.

[0051] refer to Figures 1 to 3 In an exemplary embodiment, the main line 61 passes through the bonding sheet 1; the tongue exercise device for head and neck cancer surgery can also include an extension line 71 and a third branch line 72, one end of the extension line 71 is connected to the end of the main line 61 away from the reset airbag; one end of the third branch line 72 is connected to the main line 61, wherein the second one-way valve 65 and the third branch line 72 gradually move away from the reset airbag on the main line 61.

[0052] Specifically, the extension tube 71 can also be a hose. When the user fits the fitting sheet 1 to the face, the extension tube 71 can be placed in the mouth, so that when negative pressure is generated in the reset airbag, the saliva in the user's mouth can be sucked out, preventing the saliva generated in the mouth from accumulating and flowing out of the mouth when the user is exercising the tongue, thereby affecting the exercise.

[0053] Furthermore, the sucked saliva flows through the main pipe 61 and out of the third branch pipe 72. Of course, a saliva collection chamber or other structure can be added to the third branch pipe 72, and the saliva can also be discharged directly.

[0054] refer to Figure 2 In an exemplary embodiment, the tongue exercise device for head and neck cancer surgery may further include a third one-way valve 73 , which is disposed on the third branch pipe 72 .

[0055] Specifically, the third one-way valve 73 prevents air from being sucked from the third branch tube 72 when the reset airbag is reset, thereby further increasing the suction force at the extension pipeline 71 . At the same time, the third one-way valve 73 allows saliva to flow out from the third branch tube 72 .

[0056] refer to Figure 4 In an exemplary embodiment, the tongue exercise device for postoperative head and neck cancer surgery may further include a limiting ring 8, which is disposed in the fixing cylinder 2 and has an axial direction that is the same as the first direction; wherein the piston rod 3 and the adjusting column 4 are respectively located on both sides of the limiting ring 8.

[0057] Specifically, refer to Figure 4The limiting ring 8 limits the maximum distance that the user pushes the piston rod 3, preventing the piston rod 3 from being completely pushed into the fixed cylinder 2, affecting the normal use of the tongue exercise device after head and neck cancer surgery.

[0058] At the same time, the communication area between the second branch pipe 63 and the fixed cylinder 2 is located at the end of the limiting ring 8 away from the piston rod 3, so as to ensure that the piston end of the piston rod will not block the communication area between the second branch pipe 63 and the fixed cylinder 2.

[0059] refer to Figure 4 In an exemplary embodiment, the end of the adjustment column 4 close to the fixed cylinder 2 is a frustum-shaped structure; the upper base diameter of the frustum-shaped structure is smaller than the inner diameter of the fixed cylinder 2, and the lower base diameter of the frustum-shaped structure is larger than the inner diameter of the fixed cylinder 2.

[0060] Specifically, such as Figure 4 As shown, the diameter of the upper base of the truncated cone-shaped structure is smaller than the inner diameter of the fixed cylinder 2, and the diameter of the lower base of the truncated cone-shaped structure is larger than the inner diameter of the fixed cylinder 2. In this way, the upper base of the truncated cone-shaped structure is inserted into the fixed cylinder 2. When the maximum distance between the adjusting column 4 and the fixed cylinder 2 is reduced, the truncated cone-shaped structure gradually seals the end of the fixed cylinder 2 away from the bonding sheet 1, and when sealing, the waist of the truncated cone-shaped structure is in contact with the end of the fixed cylinder 2 away from the bonding sheet 1, so that the sealing effect is better.

[0061] It should be understood that the diameter of the aforementioned adjustment column 4 refers to the diameter of the lower base of the truncated cone-shaped structure.

[0062] The above are only preferred embodiments of the present application and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
