DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] Reference Figure 1-11 This embodiment provides a tongue muscle neuromuscular stimulator, including a tongue muscle contact component 1, an electrode component 2 and a battery component 3. The electrode component 2 includes a first electrode 21, a second electrode 22, a wire 23 and a conductive connecting block 24. There are two first electrodes 21 and two second electrodes 22 respectively. One end of the tongue muscle contact component 1 is fixedly connected to the first electrode 21, and both sides of the tongue muscle contact component 1 are fixedly connected to the second electrode 22. The first electrode 21 and the second electrode 22 are respectively connected to one end of the conductive connecting block 24 through the wire 23, and the other end of the conductive connecting block 24 is fixedly connected to the battery component 3.

[0030] In this embodiment, first, the tongue muscle contact assembly 1 with the electrode assembly 2 is installed together with the battery assembly 3, and then the tongue muscle contact assembly 1 is placed in the oral cavity, so that the first electrode 21 at the front end of the tongue muscle contact assembly 1 contacts the upper surface of the tongue, and the second electrode 22 at the rear end of the tongue muscle contact assembly 1 contacts the lower two side surfaces of the tongue, and then, the tongue muscle neuromuscular stimulator is turned on by the APP of the tongue muscle neuromuscular stimulator, and the current of the battery assembly 3 is driven to flow to the first electrode 21 and the second electrode 22 respectively through the conductive connecting block 24 and the wire 23, and the start and stop time of the first electrode 21 and the second electrode 22 are controlled by the internal chip of the tongue muscle neuromuscular stimulator, thereby stimulating the muscles outside and inside the tongue of the upper respiratory tract.

[0031] The tongue muscle contact assembly 1 includes a tongue muscle contactor 11 and a second electrode movable block 12. The bottom of the tongue muscle contactor 11 is fixedly connected to the first electrode 21, and one side of the second electrode movable block 12 is fixedly connected to the second electrode 22. Fixed blocks 111 are respectively provided on both sides of the tongue muscle contactor 11, and the second electrode movable block 12 is provided in the middle of the fixed block 111. Cylinders 121 are provided at both ends of the top of the second electrode movable block 12. The cylinder 121 is hingedly connected to the fixed block 111. A first spring 122 is provided between the cylinder 121 and the fixed block 111. One end of the first spring 122 is fixedly connected to one side of the second electrode movable block 12, and the other end of the second electrode movable block 12 is fixedly connected to the top of the fixed block 111. This not only enables the second electrode 22 to effectively fit the lower end of the tongue and adapt to different tongue muscle shapes before treatment, but also further improves the therapeutic effect of the tongue muscle.

[0032] In this embodiment, when the tongue muscle contactor 11 is placed in the oral cavity, the second electrode 22 of the second electrode movable block 12 is elastically deformed by the first spring 122, causing the cylinder 121 of the second electrode movable block 12 to rotate within the fixed block 111, thereby causing the second electrode 22 to adhere to the lower surfaces of the tongue, thereby causing the lower end of the second electrode movable block 12 to reciprocate inward and outward with the movement of the tongue.

[0033] If the second electrode 22 starts the puncture work, the second electrode 22 of the second electrode movable block 12 is driven to stimulate the tongue muscles on both sides under the tongue, so that the tongue muscles on both sides under the tongue are lifted and contracted, driving the cylinder 121 of the second electrode movable block 12 to rotate under the elastic deformation of the first spring 122, thereby causing the lower end of the second electrode movable block 12 to move inward. If the second electrode 22 stops the stimulation work, the second electrode 22 of the second electrode movable block 12 will also stop stimulating the tongue muscles on both sides under the tongue, so that the tongue muscles on both sides under the tongue are relaxed and expanded, driving the cylinder 121 of the second electrode movable block 12 to rotate under the elastic deformation of the first spring 122, thereby causing the lower end of the second electrode movable block 12 to move outward.

[0034] A movable sleeve 123 is provided on the outer wall of the first spring 122 , a limiting block 1231 is provided at one end of the movable sleeve 123 , a limiting groove 1111 is provided on the fixed block 111 , and the limiting block 1231 is slidably connected to the limiting groove 1111 , thereby improving the simplicity of the overall external structure.

[0035] The other end of the movable sleeve 123 is fixedly connected to the cylinder 121 via a sealing ring 124, thereby improving the sealing of the tongue muscle neuromuscular stimulator and preventing the entry of oral saliva.

[0036] The movable sleeve 123 is provided with a plurality of adjustment grooves 1232, which are respectively engaged with the adjustment assembly 4. The adjustment assembly 4 includes a fixing member 41, an adjustment member 42 and a second spring 43. The fixing member 41 is fixedly connected to the inner wall of the fixed block 111, and the bottom of the fixing member 41 is slidably connected to one end of the adjustment member 42, and the other end of the adjustment member 42 is engaged with the adjustment groove 1232, thereby improving the fixation of the movable sleeve 123.

[0037] The cylinders 121 are fixedly connected to the driving components 5, which include a driving member 51, a driving rod 52 and an electric pusher 53. The middle part of the driving member 51 is fixedly connected to the cylinder 121 through a first bearing 511, the top of the driving member 51 is fixedly connected to one end of the driving rod 52, and the other end of the driving rod 52 is slidably connected to the electric pusher 53, thereby improving the multi-position stimulation of the tongue muscle neuromuscular stimulator and avoiding the discomfort caused by treatment at one position point.

[0038] In this embodiment, when the second electrode movable block 12 needs to be moved forward and backward, the electric pusher 53 starts working, driving the driving rod 52 to move, so that the driving member 51 moves, driving the cylinder 121 to move, and then the second electrode 22 of the second electrode movable block 12 moves forward and backward;

[0039] In the process of movement of the cylinder 121 of the second electrode movable block 12, the first spring 122 of the second electrode movable block 12 drives the movable sleeve 123 to move, so that the adjustment groove 1232 of the movable sleeve 123 passes through the adjusting member 42, and then the adjusting member 42 moves downward under the elastic force of the second spring 43, driving the bottom of the adjusting member 42 to engage with the adjusting groove 1232.

[0040] The bottom of the conductive connection block 24 is fixedly connected to the first conductive contactor 241, the two ends of the first conductive contactor 241 are respectively fixedly connected to the first magnetic block 242, and the middle of the first conductive contactor 241 is respectively fixedly connected to several conductive blocks 243. A deep groove 244 is provided at the bottom of the conductive connection block 24, and a protrusion 311 is provided at the top of the battery assembly 3. The deep groove 244 is positioned and connected to the protrusion 311.

[0041] The battery assembly 3 includes a battery shell 31 and a second conductive contactor 32. The second conductive contactor 32 is fixedly connected to the top of the shell 31. Several conductive cylinders 321 are fixedly connected to the middle of the second conductive contactor 32. The two ends of the second conductive contactor 32 are fixedly connected to the second magnetic block 322. The second magnetic block 322 and the first magnetic block 242 are magnetically connected to each other, thereby realizing the assembly and disassembly of the tongue muscle contact assembly 1 and the battery assembly 3, which is convenient for the subassembly and maintenance of the tongue muscle neuromuscular stimulator.

[0042] In this embodiment, when the tongue muscle contact assembly 1 with the electrode assembly 2 and the battery assembly 3 need to be merged, the protrusion 311 of the battery assembly 3 is docked with the deep groove 244 of the conductive connecting block 24, so that the first magnetic block 242 and the second magnetic block 322 are attracted to each other, so that the conductive block 243 and the conductive cylinder 321 can conduct electricity. When the tongue muscle contact assembly 1 with the electrode assembly 2 and the battery assembly 3 need to be separated, the first magnetic block 242 and the second magnetic block 322 are moved away from each other, so that the protrusion 311 of the battery assembly 3 and the deep groove 244 of the conductive connecting block 24 are separated.

[0043] A saliva collection component 6 is provided in the middle of the battery housing 31. The saliva collection component 6 includes a clamp 61, a peristaltic pump 62, a first hose 63, a second hose 64, and a collection tube 65. The lower end of the clamp 61 is fixedly connected to the battery housing 31, and the upper end of the clamp 61 is fixedly connected to the peristaltic pump 62 and the collection tube 65 respectively. The inlet and outlet of the peristaltic pump 62 are fixedly connected to the first hose 63 and the second hose 64 respectively. The peristaltic pump 62 is connected to the collection tube 65 through the second hose 64. Among them, the front end of the first hose 63 can be a wave type, and can be telescopically bent and adjusted. The saliva collection component 6 is not only convenient to disassemble, but also realizes the collection and processing of the peristaltic pump 62, effectively improving the comfort of using the tongue neuromuscular stimulator.

[0044] One end of the peristaltic pump 62 is fixedly connected to one end of the rotating shaft 621 , the other end of the rotating shaft 621 is fixedly connected to the handle 66 , the outer wall of the rotating shaft 621 is fixedly connected to the inner wall of the bearing 6211 , and the outer wall of the bearing 6211 is fixedly connected to the fixture 61 .

[0045] In this embodiment, when the first electrode 21 and the second electrode 22 are working, they will stimulate the oral nerves, resulting in intermittent production of saliva. By rotating the handle 66, the first hose 63 and the second hose 64 are compressed, so that the saliva flows from the first hose 63 into the second hose 64, and then flows into the collection tube 65, and the saliva is collected and processed. If disassembly is required, just remove the clamp 61 from the battery housing 31.

[0046] Working principle: First, the protrusion 311 of the battery assembly 3 is docked with the deep groove 244 of the conductive connection block 24, so that the first magnetic block 242 of the first conductive contact 241 and the second magnetic block 322 of the second conductive contact 32 are attracted to each other. The tongue muscle contact assembly 1 with the electrode assembly 2 is combined with the battery assembly 3, so that the conductive block 243 and the conductive cylinder 321 can conduct electricity.

[0047] Afterwards, the tongue muscle contactor 11 and the second electrode movable block 12 of the tongue muscle contact assembly 1 are respectively placed into the oral cavity, and the first electrode 21 of the tongue muscle contactor 11 is brought into contact with the upper surface of the tongue. Under the elastic deformation action of the first spring 122, the second electrode 22 of the second electrode movable block 12 makes the cylinder 121 of the second electrode movable block 12 rotate in the fixed block 111, so that the lower end of the second electrode movable block 12 moves back and forth in and out with the movement of the tongue to fit the lower two side surfaces of the tongue.

[0048] Then, the tongue neuromuscular stimulator is turned on by controlling the APP of the tongue neuromuscular stimulator, driving the current of the battery assembly 3 to flow to the first electrode 21 and the second electrode 22 through the conductive connection block 24 and the wire 23 respectively, and the start and stop time of the first electrode 21 and the second electrode 22 is controlled by the internal chip of the tongue neuromuscular stimulator, thereby stimulating the external and internal muscles of the tongue in the upper respiratory tract;

[0049] Then, during the treatment process, the first electrode 21 and the second electrode 22 start the stimulation work, respectively driving the first electrode 21 and the second electrode 22 of the second electrode movable block 12 to stimulate the tongue muscles, wherein the second electrode 22 causes the tongue muscles on both sides under the tongue body to lift and contract, driving the cylinder 121 of the second electrode movable block 12 to rotate under the elastic deformation of the first spring 122, thereby causing the lower end of the second electrode movable block 12 to move inward. If the second electrode 22 stops the stimulation work, the first electrode 21 and the second electrode 22 of the second electrode movable block 12 are respectively driven to stop stimulating the tongue muscles, and the second electrode 22 causes the tongue muscles on both sides under the tongue body to relax and expand outward, driving the cylinder 121 of the second electrode movable block 12 to rotate under the elastic deformation of the first spring 122, thereby causing the lower end of the second electrode movable block 12 to move outward.

[0050] When the second electrode movable block 12 needs to be moved forward or backward, the electric pusher 53 starts working, driving the driving rod 52 to move, so that the driving member 51 moves, thereby driving the cylinder 121 to move, and then the second electrode 22 of the second electrode movable block 12 moves forward or backward. In the process of moving the cylinder 121 of the second electrode movable block 12, the first spring 122 of the second electrode movable block 12 drives the movable sleeve 123 to move, so that the adjustment slot 1232 of the movable sleeve 123 passes through the adjustment member 42, and then the adjustment member 42 moves downward under the elastic force of the second spring 43, driving the bottom of the adjustment member 42 to be clamped and fixed to the adjustment slot 1232;

[0051] When the first electrode 21 and the second electrode 22 are working, they stimulate the oral nerves, causing intermittent production of saliva. By rotating the handle 66, the first hose 63 and the second hose 64 are compressed, causing the saliva to flow from the first hose 63 into the second hose 64 and then into the collection tube 65 for collection and processing.

[0052] Finally, when the treatment is finished, the first magnetic block 242 of the first conductive contact 241 and the second magnetic block 322 of the second conductive contact 32 are moved away from each other, thereby separating the battery assembly 3 and the tongue muscle contact assembly 1, and removing the saliva collection assembly 6 from the battery housing 31.
