Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a variable-frequency ultrasonic rehabilitation training device for dysphagia caused by stroke. Background Art

[0002] Currently, stroke is the second leading cause of death among people over 60 years old worldwide. It is a "three highs" disease with high morbidity, high disability rate, and high mortality rate. Approximately 51%-73% of patients have varying degrees of swallowing dysfunction. Domestic and foreign experts have proposed many treatment and rehabilitation methods for swallowing dysfunction in stroke patients, such as low-frequency pulse electrical stimulation therapy, cognitive function training, and oral sensory motor training. However, low-frequency pulse electrical stimulation therapy requires a high level of professional expertise, and cognitive function training requires a high degree of subjective cooperation from patients. There are also various methods in oral sensory motor training, such as tongue muscle strength training techniques, K-site stimulation, air pulse sensory stimulation, and modified vibrators. The modified vibrator training method can enhance local nerve sensory sensitivity, strengthen muscle contraction, achieve brain compensatory function, induce swallowing reflex, meet the requirements of oral movement, and is also portable. However, this method lacks a matching, system-stable, variable-frequency vibration mode and vibration frequency dedicated vibration swallowing disorder trainer. The existing variable-frequency ultrasonic trainer for swallowing disorders caused by stroke needs to be frequently inserted into the patient's mouth for training, and the silicone vibrating cover on the head of the trainer cannot be quickly removed for cleaning and disinfection, resulting in blind spots in the silicone vibrating cover. Conventional wiping cleaning is difficult to achieve a thorough disinfection effect. Food residues, saliva, etc. in the mouth will seep into the gap between the silicone vibrating cover and the head of the trainer. Long-term accumulation will breed a large number of bacteria, which are difficult to clean and reduce the hygienic quality of the trainer. Summary of the Invention

[0003] Purpose of the invention: The purpose of the present invention is to provide a solution to the problem that the silicone vibration cover on the head of the existing variable-frequency ultrasonic trainer for dysphagia caused by stroke cannot be quickly disassembled for cleaning and disinfection, and conventional wiping cleaning is difficult to achieve the effect of thorough disinfection. A large number of bacteria will accumulate over a long period of time and are difficult to clean, thereby reducing the sanitary quality of the trainer.

[0016] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Example like Figure 1 、 Figure 2 and Figure 4 As shown, a variable frequency ultrasonic rehabilitation trainer for dysphagia caused by stroke is provided, comprising a trainer body 1, an ultrasonic horn 2 is fixedly connected to the left side of the trainer body 1, and a vibration sleeve 3 is provided at the outer left end of the ultrasonic horn 2; A through-type plug-in hole 5 is provided on the right side of the vibration sleeve 3, and the left side of the ultrasonic horn 2 extends to the inside of the plug-in hole 5; A sliding cavity 6 is symmetrically provided on the left side of the interior of the ultrasonic horn 2. A sliding plate 7 is slidably connected to the interior of each of the two sliding cavities 6. An oblique plate 8 is fixedly connected to the opposite sides of the two sliding plates 7. A snap-fit ​​groove 9 is symmetrically provided on the inner side wall of the plug-in hole 5. The opposite sides of the two oblique plates 8 extend into the interior of the two snap-fit ​​grooves 9, respectively. A plurality of springs 10 are fixedly connected to the interiors of the two sliding cavities 6 on the opposite sides of the two sliding plates 7. When the rehabilitation trainer is used, the plug-in hole 5 of the vibration sleeve 3 is aligned with the ultrasonic amplitude transformer 2 and inserted. As the insertion is carried out, the left side of the ultrasonic amplitude transformer 2 squeezes the oblique plate 8, causing it to drive the sliding plate 7 to slide to the opposite side in the sliding cavity 6. The spring 10 is compressed. When the oblique plate 8 moves to the position corresponding to the engaging groove 9, the spring 10 recovers its deformation, pushing the sliding plate 7 to drive the oblique plate 8 to slide into the engaging groove 9, thereby realizing rapid fixation of the vibration sleeve 3 and the ultrasonic amplitude transformer 2, thereby greatly saving installation time and improving the efficiency of rehabilitation training preparation. At the same time, the stable structure formed by the spring 10 and the oblique plate 8 in conjunction with the engaging groove 9 can ensure that the vibration sleeve 3 will not loosen or fall off easily during the ultrasonic vibration treatment, thereby ensuring the stability and safety of the treatment and allowing patients to obtain continuous and effective rehabilitation training.

[0018] like Figure 1 As shown, the front surface of the training device body 1 is integrally formed with an adjustment button 4; By adjusting the switch button in the button 4, the power of the trainer body 1 is turned on and the device starts to start. At this time, the frequency adjustment button in the button 4 is used to send an instruction to the control circuit. After receiving the instruction, the control circuit adjusts the driving signal frequency of the ultrasonic generator, thereby changing the vibration frequency of the ultrasonic amplitude transformer 2 to meet the treatment needs of different patients. The switch and frequency adjustment are integrated on the button 4, and the operation is intuitive and convenient. Medical staff or patients can quickly get started and flexibly control the working status of the trainer and the ultrasonic vibration frequency to make rehabilitation training more accurate and effective.

[0019] like Figure 3 As shown, a battery compartment 11 is integrally formed inside the trainer body 1, a battery body 12 is disposed inside the battery compartment 11, a charging module 13 is disposed on the right side of the battery compartment 11, a charging slot 14 is provided on the right side of the trainer body 1, a sealing cover 15 is threadedly connected to the inside of the charging slot 14, a sealing ring 16 is fixedly connected to the left side of the sealing cover 15, the left side of the sealing ring 16 contacts the right side of the inside of the charging slot 14, and the right side of the charging module 13 extends into the inside of the charging slot 14; When the trainer needs to be charged, unscrew the sealing cover 15 on the charging slot 14, connect the charging cable to the charging module 13 to start charging. After charging is completed, screw the sealing cover 15 into the charging slot 14. The sealing ring 16 on the left side of the sealing cover 15 will be squeezed and fit tightly against the inner right side of the charging slot 14 during the process of tightening the thread, forming a waterproof barrier to prevent external moisture from entering the charging slot 14, thereby effectively protecting the internal charging module 13 from water intrusion, thereby avoiding short circuit and damage to the charging module 13 due to liquid infiltration, and extending the service life of the trainer. At the same time, even if the trainer is in a humid environment or accidentally comes into contact with liquid, it can ensure the safe operation of the equipment, reduce the risk of safety accidents caused by leakage, and make patients and medical staff feel more at ease when using it.

[0020] like Figure 3 As shown, the type of battery body 12 is a lithium iron phosphate battery; Lithium iron phosphate batteries have good thermal and chemical stability. They have a low probability of burning, exploding, and other dangerous situations under high temperature, overcharging, and short circuit conditions. Therefore, they are crucial for rehabilitation trainers because they may encounter various different environments and usage conditions during use. Safe batteries can effectively avoid safety accidents caused by battery problems and ensure the personal safety of users. Lithium iron phosphate batteries can withstand multiple charge and discharge cycles with slow performance degradation, which means that there is no need to frequently replace batteries throughout the service life of the trainer, reducing usage costs and impact on the environment.

[0021] like Figure 1 As shown, a display screen 17 is integrally formed on the front surface of the training device body 1, and a plurality of signal lights 18 are provided on the right side of the front surface of the training device body 1; The display screen 17 can display the key parameters of the trainer in real time and comprehensively, such as the current ultrasonic vibration frequency, remaining battery power, and usage time. Medical staff or patients can accurately adjust the training plan based on these data, and the signal light 18 quickly conveys the device status with different colors and flashing modes. For example, a solid green light indicates that the device is operating normally, a flashing red light indicates a fault or abnormality, and a flashing yellow light indicates that the battery is low and needs to be charged. The two work together to not only improve the convenience of device operation, but also allow users to grasp the operation status of the trainer in a timely manner, ensuring that rehabilitation training is carried out safely and efficiently.

[0022] like Figure 2 and Figure 4 As shown, a pressing cavity 19 is provided inside the vibration sleeve 3 and on opposite sides of the two engaging grooves 9. An arc-shaped pressing plate 20 is slidably connected to the inside of the two pressing cavities 19. A push plate 21 is slidably connected to the inside of the two engaging grooves 9 and on opposite sides of the two oblique plates 8. A plurality of connecting rods 22 are fixedly connected between the opposite sides of the two push plates 21 and the opposite sides of the two arc-shaped pressing plates 20. A plurality of springs 23 are fixedly connected to the opposite sides of the two arc-shaped pressing plates 20 and the inside of the two pressing cavities 19 respectively. When the vibration sleeve 3 needs to be disassembled, the two arc-shaped pressing plates 20 are pressed at the same time. The arc-shaped pressing plates 20 slide to the opposite sides in the pressing cavity 19, driving the connecting rod 22 to push the pushing plate 21 to slide in the engaging groove 9. The pushing plate 21 squeezes the oblique plate 8 to move it into the sliding cavity 6. The spring 10 is compressed, and the oblique plate 8 withdraws from the engaging groove 9, releasing the fixation of the vibration sleeve 3, and the vibration sleeve 3 can be easily pulled out from the ultrasonic amplitude rod 2, so that the disassembly method is simple and efficient, and the disassembly action can be completed with one hand, saving disassembly time and manpower, and ensuring the integrity of components such as the ultrasonic amplitude rod 2 and the vibration sleeve 3, extending the service life of the equipment, and facilitating the replacement and cleaning of the vibration sleeve 3, thereby ensuring the health and safety of rehabilitation training and the normal operation of the equipment.

[0023] like Figure 2 As shown, a second sealing ring 24 is fixedly connected to the right side of the inner wall of the plug hole 5, and the inner wall of the second sealing ring 24 contacts the outer wall of the ultrasonic horn 2; The setting of the sealing ring 24 provides reliable protection for the connection between the ultrasonic transformer 2 and the vibration sleeve 3. After the vibration sleeve 3 is fixed to the ultrasonic transformer 2 through the plug hole 5, the sealing ring 24 fits tightly to the outer wall of the ultrasonic transformer 2, effectively filling the gap between the two, and can prevent liquids such as saliva from seeping into the connection part during rehabilitation training, and prevent the appearance of sanitary dead corners inside the plug hole 5, further ensuring the hygiene of the device and improving the safety of training.

[0024] like Figure 1 and Figure 2 As shown, the entire material of the vibration sleeve 3 is made of silicone; Silicone is soft and elastic, and feels comfortable when it fits against human skin. It can reduce the discomfort caused by contact with equipment during swallowing disorder rehabilitation training and improve patient compliance. At the same time, its chemical properties are stable, it is not easy to react chemically with other substances, and it has good corrosion resistance. Even if it is in contact with skin secretions, disinfectants, etc. for a long time, it will not easily age or deteriorate, thus ensuring the service life of the product.

[0025] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
