[0002] Swallowing training is a series of rehabilitation interventions for patients with swallowing dysfunction. It aims to stimulate the pharynx through specific training methods and improve their voluntary swallowing ability. Swallowing dysfunction can be caused by a variety of factors, including neurological diseases (such as stroke, Parkinson's disease, and brain trauma), head and neck tumors, and degenerative diseases in the elderly.

[0003] Traditional training stimulation equipment stimulates the pharynx by inserting the stimulation source into the patient's mouth and directly contacting the pharynx.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0031] like Figures 1 to 6 As shown, the present invention provides a swallowing training stimulation device, which specifically includes a gun-shaped housing 1, a massage head 3, a pump liquid box 5, a piston plate 7, a temperature control box 8, a liquid inlet pipe 9, a liquid outlet pipe 10, a one-way valve 1001, a connecting pipe 11, a scattering nozzle 12 and an acidification mechanism 13; Among them, the front part of the gun-shaped shell 1 is provided with a gun barrel 2, and the front end of the gun barrel 2 away from the gun-shaped shell 1 is connected to a massage head 3, which is used to provide a structural installation body and achieve massage stimulation; Among them, the pump liquid box 5 is provided in the middle of the inner side of the gun-shaped housing 1, and the inner top of the gun-shaped housing 1 is provided with an electric push rod 6 facing vertically downward, and a piston plate 7 is slidably provided inside the pump liquid box 5. The piston plate 7 can move up and down in the pump liquid box 5. The output shaft of the electric push rod 6 passes through the top of the pump liquid box 5 and is connected to the piston plate 7, which is used to intermittently control the movement of quantitative clean water and provide a place for injecting acid; Among them, two horizontally arranged thermostats 8 are provided in the middle of the inner side of the gun-shaped housing 1, a liquid inlet pipe 9 is provided at the bottom of the pump liquid tank 5, and a liquid outlet pipe 10 is connected to the bottom of the pump liquid tank 5. The liquid outlet pipe 10 is a three-way pipe. The two pipes of the liquid outlet pipe 10 that are not connected to the pump liquid tank 5 pass through the two thermostats 8 respectively. The interior of the thermostat 8 can heat or cool the interior of the contacted pipes. By heating or cooling the clean water passing through the thermostat 8, warm stimulation and then cold stimulation of the pharynx are achieved; Among them, the end positions where the liquid inlet pipe 9 and the liquid outlet pipe 10 are connected to the pump liquid box 5 are both provided with a one-way valve 1001. The one-way valve 1001 on the liquid inlet pipe 9 is open in the direction of entering the pump liquid box 5, and the one-way valve 1001 on the liquid outlet pipe 10 is open in the direction of leaving the pump liquid box 5, which is used to achieve one-way conduction, ensuring that when the piston plate 7 in the pump liquid box 5 moves upward, clean water or acid can only be injected into the pump liquid box, and when the piston plate 7 moves downward, clean water can only be discharged from the pump liquid box; The inside of the massage head 3 is provided with two scattering nozzles 12 extending out of the massage head 3. The barrel 2 is provided with two horizontally arranged connecting pipes 11. The connecting pipes 11 connect the liquid outlet pipe 10 passing through the thermostat 8 with the scattering nozzles 12 to spray clean water onto the user's pharynx. The acidifying mechanism 13 provided on the upper portion of the gun-shaped housing 1 is used to inject acid into the pump liquid box 5 and mix it into clean water to provide a sour taste.

[0032] Among them, the gun-shaped housing 1 has a detachable liquid storage tank 4 in the middle of the lower side, and the lower end of the liquid inlet pipe 9 extends into the bottom of the inner side of the liquid storage tank 4 for storing clean water; Exemplarily, when in use, the user holds the device steadily through the gun-shaped shell 1, and then extends the gun barrel 2 together with the massage head 3 into the oral cavity, so that the massage head 3 contacts the pharynx for massage stimulation, and at the same time, controls the electric push rod 6 to start. In the initial state, the output shaft of the electric push rod 6 controls the piston plate 7 to be under the inner side of the pump liquid tank 5. After the electric push rod 6 is started, the piston plate 7 is first driven to move upward, and the space between the piston plate 7 and the bottom of the pump liquid tank 5 becomes larger. The clean water in the liquid storage tank 4 is pumped into the pump liquid tank 5 through the one-way valve 1001 of the liquid inlet pipe 9. When the piston plate 7 moves to a certain height, the electric push rod 6 drives the piston plate 7 to move downward again and finally returns to the initial position, and the liquid in the pump liquid tank 5 is pumped into the connecting pipe 11 through the liquid outlet pipe 10 and finally sprayed into the user's mouth from the scattering nozzle 12. In addition, when in use, the user can control the temperature control box 8 to start and heat or cool to a suitable temperature. Temperature, the liquid outlet pipe 10 is divided into two temperature regulating boxes 8, which can achieve the effect of different temperatures. Secondly, acid can be injected into the pump liquid box 5 through the acidification mechanism 13, giving the clean water in the pump liquid box 5 a certain degree of sourness. In this way, through the three different methods of massage by the massage head 3, contact with clean water at different temperatures and making the clean water sour, the user's pharynx is stimulated at the same time, and the combined effect enhances the sensitivity of the swallowing reflex, improves the coordination of the swallowing muscles, and enhances the autonomous swallowing ability of users with swallowing dysfunction. In addition, the injection of clean water is pumped into the user's mouth through the up and down movement of the piston plate 7 in the pump liquid box 5, so as to achieve intermittent pumping of a certain amount of clean water into the user's mouth, which is convenient for controlling the injection amount and avoiding excessive stimulation when stimulating swallowing, causing discomfort to the user and coughing or vomiting reaction. The structure of the entire device is simple and easy to control, which is convenient for medical staff or patients to use independently, and reduces the training threshold.

[0033] like Figures 4 to 6 As shown, the acidification mechanism 13 specifically includes an acid liquid tank 1301, a needle tube 1302, an acid liquid tube 1304, a piston plate 1305, a connecting frame 1306, a supporting frame 1307, a screw rod 1308 and a one-way nozzle 1309; Among them, the top rear side of the gun-shaped housing 1 is detachably provided with an acid tank 1301 for storing acid; Among them, a needle tube 1302 is provided on the inside of the gun-shaped housing 1, and the acid tank 1301 is sealed by a rubber plug and an aluminum-plastic combination cover. The needle tube 1302 can penetrate the rubber plug and communicate with the acid tank 1301. The end of the needle tube 1302 not in communication with the acid tank 1301 is provided with a delivery tube 1303. The delivery tube 1303 is in communication with the end of the acid tube 1304 that passes through the top of the pump liquid box 5. The middle part of the needle tube 1302 is connected to an air inlet pipe 1310 for continuously delivering the acid in the acid tank 1301 into the acid tube 1304. Among them, the pump liquid box 5 is provided with multiple acid liquid pipes 1304, and the acid liquid pipes 1304 all pass through the piston plate 7 and the top of the pump liquid box 5. The acid liquid pipes 1304 are provided with a sliding seal inside the acid liquid pipes 1304, which are used to control the amount of acid stored in the acid liquid pipes 1304 by the up and down movement of the piston plate 1305; Among them, a connecting frame 1306 is connected between the tops of the piston plates 1305 of all different acid liquid tubes 1304. The connecting frames 1306 slide through the tops of the acid liquid tubes 1304. A support frame 1307 is provided on the top of the gun-shaped housing 1. The support frame 1307 is located directly above the connecting frame 1306. A screw rod 1308 is rotatably provided in the middle position of the top of the support frame 1307. The screw rod 1308 is threadedly connected to the middle position of the top of the connecting frame 1306, and is used to simultaneously control the positions of all piston plates 1305 in the acid liquid tubes 1304 through the screw rod 1308 and the connecting frame 1306. Among them, multiple groups of one-way nozzles 1309 are evenly spaced on the side of the acid pipe 1304. The one-way nozzles 1309 can only conduct one-way from the acid pipe 1304 to the pump liquid box 5, which is used to ensure that the acid can only be injected into the acid tank 1301 through the acid pipe 1304, while preventing clean water from entering the acid pipe 1304.

[0034] When it is necessary to inject acid into the pump liquid box 5 to acidify clean water, the user first places the acid liquid tube 1304 on the upper part of the gun-shaped housing 1 and makes the needle tube 1302 penetrate into the acid liquid tank 1301. The acid in the acid liquid tank 1301 continuously enters the acid liquid tube 1304 through the needle tube 1302 and the delivery tube 1303. During this process, the air intake pipe 1310 intakes air into the acid liquid tank 1301 to assist the acid liquid to enter the acid liquid tube 1304 normally. When the piston plate 7 moves from the bottom to the top of the pump liquid box 5 driven by the electric push rod 6, clean water enters the pump liquid box 5 from the liquid intake pipe 9, and the acid also flows from the acid tube 1304 through the one-way nozzle 13 09 enters the pump liquid box 5 to acidify the clean water, and the user controls the connecting frame 1306 by rotating the screw rod 1308 to drive the piston plate 1305 to move up and down in the acid liquid tube 1304, so as to adjust the timing when the acid starts to enter the pump liquid box 5. The entry of the acid depends entirely on the negative pressure formed by the upward movement of the piston plate 7, and the clean water also continuously enters the pump liquid box 5 through the liquid inlet pipe 9. In this way, the height position of the piston plate 1305 inside the acid liquid tube 1304 can fully control the amount of acid entering, and finally achieve the effect of controlling the acidity of the clean water sprayed into the mouth, which is convenient for the user to adjust according to his own needs and adaptability.

[0035] Example 2 like Figure 7 and Figure 8As shown, on the basis of Example 1, it also includes a nozzle 14. A cylindrical nozzle 14 is provided on the side of the gun-shaped housing 1 close to the gun barrel 2. The gun barrel 2 is tapered with a diameter gradually decreasing toward the massage head 3. The nozzle 14 surrounds the gun barrel 2. There is a certain gap between the nozzle 14 and the gun barrel 2, and a certain gap is also maintained between the end of the nozzle 14 not connected to the gun-shaped housing 1 and the massage head 3. Support rods 15 are provided above and below the nozzle 14 and the cone. The support rod 15 is arc-shaped near the nozzle 14, and an exhaust pipe 16 is connected to the bottom of the nozzle 14 near the gun-shaped housing 1.

[0036] After the gun barrel 2 is inserted into the oral cavity, the nozzle 14 is simultaneously inserted into the oral cavity and contacts the user's mouth instead of the gun barrel 2. When the user is stimulated and vomits, the vomit can pass through the gap between the nozzle 14 and the gun barrel 2 into the discharge pipe 16 and then be discharged, thereby preventing the vomit from being unable to be discharged in time and causing harm to the user such as aspiration, pneumonia, or even suffocation, thereby affecting the safety and rehabilitation effect of the critical rehabilitation swallowing stimulation exercise. The support rod 15 supporting the nozzle 14 and the gun barrel 2 is symmetrically arranged in an upper and lower manner. When the user has a stress reaction, it can support the user's teeth clenching action to prevent the nozzle 14 from being squeezed and deformed and affecting the discharge of vomit.

[0037] like Figure 8 and Figure 9 As shown, on the basis of Example 1, it also includes a filter 17, a filter 17 is provided between the inner side of the nozzle 14 and the barrel 2, and the filter 17 is inclined downward toward the massage head 3; a fixed frame 18, a fixed frame 18 is provided between the top of the filter 17 and the gun-shaped housing 1; and rollers 19, rollers 19 are rotatably provided at even intervals inside the fixed frame 18.

[0038] The filter screen 17 arranged obliquely in the nozzle 14 can force the vomitus to separate into solid and liquid when passing through the nozzle 14, and allow the solid vomitus to move upward along the filter screen 17 into the top of the fixed frame 18, and the roller 19 rotatably arranged on the fixed frame 18 can better move the solid vomitus to the rear of the fixed frame 18, thereby preventing the solid vomitus from clogging the discharge pipe 16 and affecting the discharge effect of the vomitus.

[0039] like Figure 10 and Figure 11 As shown, based on embodiment 1, it also includes a support frame 20, a turbine fan 21, a sealing cover 22, a synchronous pulley set 23 and a propeller 24; Among them, a support frame 20 is provided inside the end close to the liquid inlet pipe 9 and the liquid outlet pipe 10, and a turbine fan 21 is rotatably provided on the support frame 20. A sealing cover 22 is penetrated between the liquid inlet pipe 9 and the liquid outlet pipe 10 located below the support frame 20. The central axis of the turbine fan 21 penetrates the sealing cover 22. A propeller 24 is rotatably provided at the bottom of the inner side of the pump liquid tank 5 and located between the liquid inlet pipe 9 and the liquid outlet pipe 10. The central axis of the propeller 24 penetrates the bottom of the pump liquid tank 5 and the middle of the sealing cover 22. A synchronous pulley group 23 for transmission is provided between the two turbine fans 21 and the central axis of the propeller 24, and the synchronous pulley group 23 is located inside the sealing cover 22.

[0040] When the piston plate 7 moves to allow clean water to enter the pump liquid box or be discharged from the pump liquid box 5, the clean water can drive the turbine fan 21 to rotate when passing through the turbine fan 21. The rotation of the turbine fan 21 drives the propeller 24 to rotate through the synchronous pulley group 23, so that the propeller 24 stirs the clean water in the pump liquid box 5, so that the acid liquid and the clean water are completely mixed. The synchronous pulley group 23 is sealed and surrounded by the support frame 20, which can prevent the clean water from contacting the synchronous pulley group 23 and contaminating the clean water.

[0041] like Figure 1 As shown, based on the embodiment 1, it further includes a display module 25 . The top of the gun-shaped housing 1 is provided with a display module 25 for displaying relevant data.

[0042] The display module 25 disposed on the top of the gun-shaped housing 1 is electrically connected to the temperature control box 8 and the electric push rod 6, making it convenient for the user to observe and adjust the data.

[0043] like Figure 12 As shown, based on Example 1, a distance sensor 26 is further included, and the distance sensor 26 is provided at corresponding positions above and below the connecting frame 1306 and the supporting frame 1307.

[0044] The distance sensor 26 between the connecting frame 1306 and the supporting frame 1307 can detect the distance between the connecting frame 1306 and the supporting frame 1307, so that the user can more accurately adjust the position of the piston plate 1305 in the acid tube 1304, thereby precisely adjusting the ratio of the acid to the clean water.

[0045] The trigger of the gun-shaped housing 1 can be pulled and is electrically connected to the electric push rod 6 for control.

[0046] Patients can control the temperature and acid stimulation time through the trigger, and carry out stimulation therapy according to the patient's physiological rhythm, thereby more effectively improving the symptoms of dysphagia.
