Description

Technical Field

[0001] The invention relates to the technical field of tongue suckers, and in particular to a tongue sucker with an anti-falling structure. Background Art

[0002] The tongue suction device, also known as the tongue muscle rehabilitation device, is a common oral physiotherapy device. It mainly uses the principle of negative pressure suction to pull the tongue out of the mouth. It can perform rehabilitation training for a crooked tongue, and can also lift the tongue to prevent tongue posterior prolapse during acute attacks of hemiplegia and stroke. It is especially convenient when providing oral care for comatose patients.

[0003] However, the currently available tongue sucker does not have an anti-slip structure, and the negative pressure during adsorption cannot be controlled. This results in that if the negative pressure is small, the tongue sucker has little attraction to the tongue and cannot achieve the purpose of training or fixation, and it is easy to fall off. If the negative pressure is large, the tongue will be over-adsorbed and congested, causing discomfort to the patient. At the same time, the existing tongue sucker does not have a quick-release structure, and is separated and disassembled from the tongue by direct pulling. During disassembly, the tongue is strongly pulled, the comfort is poor, and the practicality is not high. Summary of the invention

[0004] The disclosed embodiment relates to a tongue suction device with an anti-falling structure, which comprises a negative pressure component and a control component. The negative pressure component can generate negative pressure and adsorb the tongue through a tongue suction seat, thereby realizing rehabilitation training and tongue lifting and preventing the tongue from falling back. At the same time, under the action of the control component, the negative pressure component can achieve stable adsorption between the tongue suction seat and the tongue by adjusting the magnitude of the negative pressure, thereby avoiding the phenomenon of falling off or discomfort caused by excessive adsorption force. The tongue suction seat and the tongue can stably maintain a suitable adsorption force to avoid accidental falling off between the tongue and the tongue suction seat. The device is flexible and stable to use and can be adapted to physical therapy use for patients with different medical conditions. When used in conjunction with an anti-falling abutment plate, the anti-falling abutment plate can be abutted against the upper and lower lips of the patient's mouth, thereby effectively preventing the tongue from falling back. The device is stable to use. The negative pressure component also has a disassembly structure. When disassembling, the negative pressure inside the tongue suction seat can quickly disappear to complete the separation between the tongue and the tongue suction seat, thereby reducing the discomfort of the patient when using the device.

[0037] Please refer to Figures 1 to 10 As shown:

[0039] In the embodiment of the present disclosure, a piston cavity 1011 and a negative pressure channel 1012 are respectively provided on both sides of the interior of the operating housing 101, and the negative pressure piston 102 is located inside the piston cavity 1011, and the outer end of the negative pressure channel 1012 is connected to the interior of the tongue suction seat 301, and a reset channel 1013 and a generating channel 1014 are respectively provided in the middle of the operating housing 101, and the two ends of the reset channel 1013 connect the piston cavity 1011 and the outside of the operating housing 101, and the two ends of the generating channel 1014 connect the negative pressure channel 1012. The reset channel 1013 and the generation channel 1014 are connected to each other, and an exhaust check valve 113 and an air suction check valve 114 are respectively arranged inside. When the front end of the tongue is inserted into the tongue suction seat 301, negative pressure can be generated by the negative pressure component 1 to realize the negative pressure adsorption connection between the tongue suction seat 301 and the tongue. When the negative pressure piston 102 is pumped back and forth, negative pressure can be generated and continuously increased inside the tongue suction seat 301. When the negative pressure piston 102 is pulled outward, the air inside the tongue suction seat 301 can The air is drawn into the piston chamber 1011 through the negative pressure channel 1012, the working channel 1032 and the generating channel 1014, so that negative pressure is generated inside the tongue suction seat 301 to realize the suction connection operation with the tongue. When the negative pressure piston 102 is pushed inward, the air inside the piston chamber 1011 can be discharged through the reset channel 1013, so that the reciprocating pumping of the negative pressure piston 102 can realize the generation and continuous increase of negative pressure inside the tongue suction seat 301 for use, and the exhaust check valve 113 and the suction check valve 114 can be used. The gas flow direction inside the operating shell 101 is fixed, and the use is stable. After the tongue suction seat 301 is adsorbed and connected to the tongue, the crooked tongue can be rehabilitated by pulling the tongue out of the mouth. The tongue suction component 3 also includes an anti-slip plate 302, and the anti-slip plate 302 is fixedly installed on the outside of the tongue suction seat 301. Since the anti-slip plate 302 will contact the position of the upper and lower lips of the patient's mouth, it can effectively lift the tongue of patients with hemiplegia, acute stroke and coma to prevent the tongue from falling back. The use is stable and the operation is convenient.

[0040] In the embodiment of the present disclosure, a return spring 1031 is provided on the side of the release seat 103, and the two ends of the return spring 1031 are respectively against the inside of the release seat 103 and the inside of the operating shell 101, and a working channel 1032 is provided inside the release seat 103. When the release seat 103 is not pressed by an external force, under the action of the return spring 1031, the working channel 1032 connects the negative pressure channel 1012 with the generating channel 1014. A release channel 1033 is provided inside the release seat 103, and the release channel 1033 is located at the top of the working channel 1032. When the release seat 103 is pressed, the release channel 1033 can connect the negative pressure channel 1012 with the outside of the operating shell 101. In use, when it is necessary to release the negative pressure between the tongue suction seat 301 and the tongue, When the adsorption connection relationship is reached, it is only necessary to press the release seat 103. When the release seat 103 is pressed, the reset spring 1031 will be compressed, and at this time the release channel 1033 is aligned with the negative pressure channel 1012 for use. Under the action of the negative pressure inside the tongue suction seat 301, the external gas can enter the interior of the tongue suction seat 301 through the release channel 1033 and the negative pressure channel 1012, thereby eliminating the negative pressure inside the tongue suction seat 301, so that the tongue and the tongue suction seat 301 can lose the connection relationship, which is convenient for disassembly operation. After loosening the release seat 103, the release seat 103 moves up and resets under the action of the reset spring 1031, and the connection relationship between the working channel 1032, the negative pressure channel 1012 and the generating channel 1014 is restored, which is convenient for subsequent normal use and easy to operate.

[0041] In the embodiment of the present disclosure, a control air cavity 1015 is provided on the side of the operating housing 101, and the control piston 203 is located inside the control air cavity 1015. The control air cavity 1015 connects the outside of the operating housing 101 with the generating channel 1014. A closed tension spring 2021 is provided on the side of the positioning block 202, and the two ends of the closed tension spring 2021 are respectively fixedly mounted on the sides of the control piston 203 and the positioning block 202. Under the action of the closed tension spring 2021, the control piston 203 blocks the control air cavity 1015. During use, the control component 2 can achieve a stable connection between the tongue suction seat 301 and the tongue by controlling the maximum negative pressure that the negative pressure component 1 can generate, thereby avoiding the phenomenon that the tongue and the tongue suction seat 301 accidentally fall off due to too small a negative pressure. At the same time, the maximum negative pressure is limited, which can also effectively avoid the phenomenon that the negative pressure adsorption force is too large and causes discomfort during use. The use is stable. When the negative pressure component 1 generates negative pressure, when the negative pressure is less than the force of the closed tension spring 221 on the control piston 203, When the negative pressure is greater than the force of the closing tension spring 2021 on the control piston 203, the control piston 203 will be moved in the direction of the generating channel 1014 and the closing tension spring 2021 will be elongated. After the movement, the control piston 203 can release the blocking state of the control air chamber 1015, so that the external gas can enter the generating channel 1014 and finally enter the piston chamber 1011, so that when the negative pressure piston 102 is pulled out, the negative pressure adsorption force inside the tongue suction seat 301 will not continue to increase, and the function of limiting the maximum negative pressure adsorption force is realized. Under the action of the suction one-way valve 114, the negative pressure originally generated inside the tongue suction seat 301 will not disappear, so it can be used stably, ensuring the stable adsorption connection between the tongue and the tongue suction seat 301, avoiding the occurrence of accidental detachment, and having extremely strong stability.

[0042] In the disclosed embodiment, the outside of the positioning block 202 is provided with a thread, and the positioning block 202 is screwed to the inside of the control knob 201 through the thread. During use, the maximum negative pressure adsorption force value that the negative pressure component 1 can generate through the control component 2 can be freely adjusted and used, and can be adapted to patients with different medical conditions. When the control knob 201 is rotated, the control knob 201 can drive the positioning block 202 to move through the thread. When the positioning block 202 moves, the initial extension length of the closed tension spring 2021 can be changed, that is, the magnitude of the force of the closed tension spring 2021 on the control piston 203 is changed, thereby changing the maximum negative pressure adsorption force value that the negative pressure component 1 can generate through the control component 2. The regulation is convenient and flexible, and the adaptability is strong.

[0043] Specific usage and function of this embodiment: In the present invention, after the front end of the tongue is inserted into the interior of the tongue suction seat 301, negative pressure can be generated by the negative pressure component 1 to realize the negative pressure adsorption connection between the tongue suction seat 301 and the tongue. When the negative pressure piston 102 is pumped back and forth, negative pressure can be generated and continuously increased inside the tongue suction seat 301. When the negative pressure piston 102 is pulled outward, the air inside the tongue suction seat 301 can be drawn into the interior of the piston cavity 1011 through the negative pressure channel 1012, the working channel 1032 and the generating channel 1014, so that negative pressure is generated inside the tongue suction seat 301 to realize the adsorption connection operation with the tongue. When the negative pressure piston 102 is pushed inward, the air inside the piston cavity 1011 can be drawn into the interior of the piston cavity 1011 through the reset channel 1014. 013 is discharged, so that the reciprocating pumping negative pressure piston 102 can realize the generation and continuous increase of negative pressure inside the tongue suction seat 301 for use, and under the action of the exhaust check valve 113 and the intake check valve 114, the gas flow direction inside the operating shell 101 is fixed, and the use is stable. When the tongue suction seat 301 is adsorbed and connected with the tongue, the crooked tongue can be rehabilitated by pulling the tongue out of the oral cavity, and because the anti-dropping plate 302 will contact the position of the upper and lower lips of the patient's mouth, it can effectively lift the tongue of hemiplegic, acute stroke and comatose patients to prevent the tongue from falling back. When it is necessary to release the negative pressure adsorption connection between the tongue suction seat 301 and the tongue, it is only necessary to press the release seat 103. When the release seat 103 is pressed After the tongue holder 301 is lowered, the reset spring 1031 will be compressed, and at this time, the release channel 1033 is aligned with the negative pressure channel 1012 for use. Under the action of the negative pressure inside the tongue holder 301, the external gas can enter the interior of the tongue holder 301 through the release channel 1033 and the negative pressure channel 1012, thereby eliminating the negative pressure inside the tongue holder 301, so that the tongue and the tongue holder 301 can lose the connection relationship, which is convenient for disassembly operation. After the release seat 103 is loosened, the release seat 103 is moved up and reset under the action of the reset spring 1031, and the connection relationship between the working channel 1032, the negative pressure channel 1012 and the generating channel 1014 is restored, which is convenient for subsequent normal use. The control component 2 can generate the negative pressure by controlling the negative pressure component 1. The maximum negative pressure generated can achieve a stable connection between the tongue suction seat 301 and the tongue, avoiding the accidental detachment of the tongue from the tongue suction seat 301 due to the low negative pressure. At the same time, the maximum negative pressure is limited, which can also effectively avoid the discomfort caused by excessive negative pressure adsorption during use. The use is stable. When the negative pressure component 1 generates negative pressure, when the negative pressure is less than the force of the closed tension spring 2021 on the control piston 203, the control air cavity 1015 is always in a blocked state, so that the negative pressure inside the tongue suction seat 301 can be stably generated and increased for use. When the negative pressure is greater than the force of the closed tension spring 2021 on the control piston 203, the resistance when the negative pressure is generated is large.Therefore, the control piston 203 will be moved in the direction of the generating channel 1014 and the closed tension spring 2021 will be lengthened. After the movement, the control piston 203 can release the blocking state of the control air chamber 1015, so that the external gas can enter the interior of the generating channel 1014 at this time, and finally enter the interior of the piston chamber 1011, so that when the negative pressure piston 102 is pulled out thereafter, the negative pressure adsorption force inside the tongue suction seat 301 will not continue to increase, thereby realizing the function of limiting the maximum negative pressure adsorption force, and under the action of the suction one-way valve 114, the negative pressure originally generated inside the tongue suction seat 301 will not disappear, so it can be used stably, ensuring the tongue The stable adsorption connection between the head and the tongue suction seat 301 can avoid accidental detachment. The maximum negative pressure adsorption strength value that the negative pressure component 1 can generate through the control component 2 can be freely adjusted and used, and can be used by patients with different conditions. When the control knob 201 is turned, the control knob 201 can drive the positioning block 202 to move through the thread. When the positioning block 202 moves, the initial expansion length of the closed tension spring 2021 can be changed, that is, the size of the force of the closed tension spring 2021 on the control piston 203 is changed, thereby changing the maximum negative pressure adsorption strength value that the negative pressure component 1 can generate through the control component 2.
