Description

Technical Field

[0001] This invention relates to the field of swallowing simulation technology for stroke patients, specifically a simulation training device for preventing swallowing disorders in stroke patients. Background Technology

[0002] Rehabilitation training for stroke patients with swallowing disorders generally includes: dietary adjustments, swallowing training, speech therapy, physical therapy, and medication. Swallowing training primarily involves professional rehabilitation therapists and assistive devices to restore swallowing function. This training includes chewing, throat muscle exercises, and swallowing maneuvers. Simultaneously, speech therapy helps patients regain normal swallowing function and teaches techniques for opening and closing the mouth, ensuring correct posture and breathing to improve swallowing ability.

[0003] However, existing rehabilitation training equipment has relatively limited functions. During rehabilitation training, it is necessary to switch between different training devices, and the linkage between devices cannot be guaranteed. When training chewing and biting strength, only this function can be trained. When improving sensory abilities, only this function can be trained. It cannot be guaranteed that the lips and tongue are simultaneously sensing when chewing and biting in daily life. It cannot effectively simulate the process in single training sessions, resulting in poor results. At the same time, the training intensity of existing training devices is limited and cannot be adjusted according to different patients at different recovery stages. Moreover, the monotonous and repetitive training can cause patients to become bored with the rehabilitation simulation training, which is not conducive to their recovery.

[0004] Furthermore, in chewing and biting training, doctors can only make a general judgment on the patient's recovery by asking the patient about the number of bites during the exercise and the patient's feelings. There are no clear judgment criteria and it is impossible to provide targeted intervention measures. Therefore, this method is not conducive to developing effective training and medication based on the patient's recovery. This situation can lead to psychological problems such as anxiety and frustration in patients during the recovery stage, thereby affecting the recovery effect.

[0005] Therefore, a simulation training device for preventing swallowing disorders in stroke patients was proposed to address the above problems. Summary of the Invention

[0012] Preferably, the flexible sensitivity enhancement component includes an elastic sheet, with its two ends fixedly connected to a first dental clip and a second dental clip, respectively. A tongue depressor is fixedly connected to the tip of the elastic sheet, and massage particles are fixedly connected at equal intervals on the bottom surface of the tongue depressor.

[0019] Compared with the prior art, the present invention provides a simulation training device for preventing dysphagia in stroke patients, which has the following beneficial effects:

[0020] 1. By setting adjustable exercise components and flexible sensitivity promotion components in the adjustable swallowing disorder exercise mechanism, it is different from the existing rehabilitation training equipment with relatively simple functions, which requires changing exercise devices back and forth during rehabilitation training. It can ensure the linkage between training between devices, and effectively train the patient's lips and tongue to receive sensory training at the same time during chewing training. It is close to life, effectively simulates, and has better results.

[0021] 2. With the adjustable swallowing disorder training device, the chewing and biting force during patient simulation training can be adjusted by adjusting the position of the sliding block on the first adjustment ruler and the other sliding block on the second adjustment ruler. This is different from and superior to the training devices in the existing technology, which have a single training force and cannot be adjusted according to different patients at different recovery stages. Moreover, the single and repetitive training will cause patients to become bored with the rehabilitation simulation training, which is not conducive to the patient's recovery.

[0022] 3. Through the establishment of feedback analysis institutions, patients' biting force can be directly fed back. Unlike the current medical judgment, doctors no longer need to make a general judgment on the patient's recovery by asking the patient about the number of bites during exercise and the patient's feelings. There are clear judgment criteria, which can accurately provide targeted intervention measures, formulate effective training and medication for the patient's recovery, and avoid the patient's anxiety, frustration and other psychological problems during the recovery stage, which will affect the recovery effect.

[0023] 4. By using the retaining spring and the setting of spring A and spring B, it can effectively assist the patient in opening the oral cavity, and at the same time, it can ensure that the transmission medium filled in the bottom of the air pusher A in the fluid cavity, the connecting tube and the interlocking tube, as well as the gas in the interlocking tube and the transverse column cavity, return to the initial position after each chewing and biting, waiting for the next work to be carried out, thus ensuring the continuity of the feedback analysis mechanism.

[0024] 5. By using magnets and Hall switches, the writing pen can be synchronized with the engagement process in the later stages, effectively enabling writing and recording while the paper is wrapped around the pen. This ensures the synchronization of the operation and recording, and the synchronization is achieved with only two parts, reducing the number of parts in the device and reducing later maintenance costs.

[0048] in:

[0049] Feedback analysis unit 3 is mainly used to help doctors have a direct understanding of patients who exercise chewing, so as to provide them with appropriate treatment measures, which is different from the existing situation where only exercise can be performed but cannot assist doctors in treatment.

[0050] The lifting frame 301 can move vertically under electronic control, providing patients with an optimal exercise height.

[0051] The magnet 302 is mainly used in conjunction with the Hall switch 303, and the Hall switch 303 is electrically connected to the motor that drives the first winding column 310.

[0052] The fluid cavity 304, the connecting pipe 305, and the bottom of the thruster A307 in the interlocking pipe 306 are filled with a transmission medium, which can be implemented as air.

[0053] Spring A308 is mainly used for the reset of thruster A307.

[0054] The first winding column 310 is driven by a motor.

[0055] The writing pen 317 can be used to write on the recording paper 312, thereby indirectly providing feedback to train the patient's chewing and biting strength.

[0056] The working principle of all the content in the above embodiments is as follows:

[0057] In the initial state:

[0058] The initial state of the components in the adjustable swallowing disorder training mechanism 2: the first lip placement chamber 214 is not in contact with the second lip placement chamber 216, the first tooth retainer 215 is not in contact with the second tooth retainer 217, the elastic sheet 221 is not subjected to external force and is not deformed, and the retaining spring 2111 is not subjected to external force and is not compressed.

[0059] Initial state of components in feedback analysis mechanism 3: magnet 302 and Hall switch 303 are not in contact, spring A308 is not compressed, motor driving first winding column 310 is not working, and spring B316 is not compressed.

[0060] The following is the first innovation: the working process of the adjustable exercise component 21 for adjusting the intensity of swallowing and chewing exercises, and the flexibility and sensitivity enhancement component 22 for assisting in improving the flexibility of the patient's tongue and lips:

[0061] The lever principle, also known as the "lever balance condition," states that for a lever to be balanced, the two forces acting on it (the product of torque and lever arm) must be equal. That is: effort × effort arm = resistance × resistance arm, expressed algebraically as F1·L1 = F2·L2.

[0062] It should be noted that, under the premise of the action of the retaining spring 2111, F1 is the force of the rotating hinge 212 to limit the first adjusting ruler 211 from tilting up, L1 is the length of the sliding block 219 from the rotating hinge 212, F2 is the chewing and biting force of the patient, and L2 is the length of the sliding block 219 from the first lip placement compartment 214.

[0063] By adjusting the positions of the two fixed sliding blocks 219 on the first adjusting ruler 211 and the second adjusting ruler 213, the size of the lever arm (L) is changed, thereby indirectly changing the biting force of the exercise patient.

[0064] Preparation for simulation training: The patient places the upper and lower lips in the first lip placement chamber 214 and the second lip placement chamber 216 respectively, and then the first tooth clip 215 and the second tooth clip 217 are clipped onto the upper and lower teeth in the mouth. At this time, the tongue depressor 222 is pressed on the patient's tongue.

[0065] When using it, the chewing force needs to be adjusted according to the patient's own condition. At this time, the fixed threaded post 2110 on the sliding block 219 is twisted by the screw. Then, the sliding block 219 is slid on the first adjusting ruler 211 as needed. With the help of the scale line on the first adjusting ruler 211, the required position is determined, which corresponds to the chewing force. Then, the fixed threaded post 2110 on the sliding block 219 is rotated so that the fixed threaded post 2110 is screwed into the fixed through hole 218 opened on the first adjusting ruler 211. At this time, the position of the sliding block 219 is fixed. Similarly, the sliding block 219 on the second adjusting ruler 213 is also adjusted and fixed in the same way. After the adjustment and fixation are completed, the patient can perform simulated exercise.

[0066] Furthermore, during patient occlusion, the first lip placement chamber 214 and the second lip placement chamber 216, as well as the first tooth retainer 215 and the second tooth retainer 217, move closer together. At this time, the Hall switch 303 in the first lip placement chamber 214 and the magnet 302 in the second lip placement chamber 216 gradually approach each other. Furthermore, since the spring plate 221 is known to be designed in a ">" shape and has a certain degree of elasticity, during the aforementioned movement of the first lip placement chamber 214 and the second lip placement chamber 216 towards each other, the ">" shape... The end will move to the right, thereby moving the tongue depressor 222 on the patient's tongue. At this time, the massage particles 223 on the tongue depressor 222 will rub against the patient's tongue surface. Furthermore, due to the patient's biting and chewing actions, the lips placed in the first lip placement chamber 214 and the second lip placement chamber 216 will also be rubbed by the lip massage protrusions 224. That is, when the patient makes chewing and biting actions, the patient's tongue and lip perception will also be exercised. This design is different from the single training method in the existing technology and helps to improve the training effect.

[0067] That is, by setting up the adjustable exercise component 21 and the flexible sensitivity promotion component 22 in the adjustable swallowing disorder exercise mechanism 2, it is different from the existing rehabilitation training equipment with relatively simple functions. During rehabilitation training, the exercise device needs to be changed back and forth, and the linkage between the devices cannot be guaranteed. It effectively trains the patient's lips and tongue to sense simultaneously during chewing training. It is close to life, effectively simulates, and has better results.

[0068] Furthermore, in the later stages of patient simulation training, different chewing and biting forces can be adjusted. Specifically, when the sliding block 219 is closer to the first lip placement chamber 214 and the second lip placement chamber 216, that is, when L1 increases and L2 decreases, under the premise that F1 remains unchanged, the biting force (F2) required by the patient will be greater. Conversely, the required biting force will be smaller. That is, under the setting of the adjustable swallowing disorder training mechanism 2, by adjusting the position of the sliding block 219 on the first adjustment ruler 211 and the other sliding block 219 on the second adjustment ruler 213, the chewing and biting force during patient simulation training can be adjusted. This is different from and superior to the training devices in the prior art, which have a single training force and cannot be adjusted according to different patients at different recovery stages. Moreover, the single and repetitive training will cause patients to become bored with rehabilitation simulation training, which is not conducive to the patient's recovery.

[0069] Please refer to the above work process. Figures 1 to 3 , Figures 5 to 8 .

[0070] The following is the second innovation point: the working process of feedback analysis unit 3 used to record and provide feedback on the intensity of patients' biting and chewing exercises:

[0071] The magnet 302 and the Hall switch 303 work together to ensure the winding action of the first winding post 310 and the second winding post 311 on the recording paper 312, providing the necessary conditions for the writing pen 317 to move and record. The movement of the gas inside the interlocking tube 306 and the transverse column cavity 313 indirectly drives the writing pen 317 to move laterally, so that writing and drawing can be done on the recording paper 312, turning the non-intuitive interlocking into an intuitive line change.

[0072] Furthermore, during the later stages of occlusion, when the first lip placement chamber 214 and the second lip placement chamber 216, as well as the first tooth retainer 215 and the second tooth retainer 217, come into contact and compress, the fluid chamber 304, the connecting pipe 305, and the bottom of the air-push plate A307 in the fitting pipe 306, filled with the transmission medium, will undergo positional changes during this compression process. (See attached diagram.) Figure 9 as well as Figure 10At this time, the medium will push the air pusher A307 upward, and the spring A308 will be compressed. Since the fitting tube 306 and the transverse column cavity 313 are a closed space, the gas pushed by the air pusher A307 will enter the transverse column cavity 313. With the intervention of the gas, the air pusher B314 in the transverse column cavity 313 will move away from the fitting tube 306. In this way, the air pusher B314 will carry the writing pen 317 at the outer end of the moving column 315 to move laterally to the left on the recording paper 312. At this time, the spring B316 is compressed.

[0073] Furthermore, in the later stage of occlusion, when the first lip placement chamber 214 and the second lip placement chamber 216, as well as the first tooth retainer 215 and the second tooth retainer 217 come into contact and are pressed together, the magnet 302 and the Hall switch 303 will approach each other. At this time, there is an electrical connection between the magnet 302 and the Hall switch 303. The motor used to drive the first winding column 310 to rotate will rotate the first winding column 310, thereby winding the recording paper 312.

[0074] The horizontal leftward movement of the writing pen 317 and the winding of the first winding post 310 onto the recording paper 312 both occur in the later stage of engagement. Therefore, in this situation, the writing pen 317 moves horizontally to the left while the recording paper 312 moves upward.

[0075] Furthermore, when the patient stops biting, the magnet 302 and the Hall switch 303 move away from each other. At this time, the first winding post 310 stops winding around the recording paper 312, and the writing pen 317 will move laterally to the right when the spring B316 returns to its initial state. Furthermore, as the biting action changes, the writing pen 317 will move back and forth on the recording paper 312, thereby converting the biting force into a zigzag line for feedback.

[0076] In other words, by setting up feedback analysis mechanism 3, the patient's biting force can be directly fed back. Unlike the current medical judgment, doctors no longer need to make a general judgment on the patient's recovery by asking the patient about the number of bites during exercise and the patient's feelings. There are clear judgment criteria, which can accurately provide targeted intervention measures, develop effective training and medication for the patient's recovery, and avoid the patient's anxiety, frustration and other psychological problems during the recovery stage, which will affect the recovery effect.

[0077] By setting up the spring 2111, spring A308 and spring B316, the patient can be effectively assisted in opening the oral cavity. At the same time, the transmission medium filled in the bottom of the air-pushing plate A307 in the fluid cavity 304, the connecting tube 305 and the interlocking tube 306, as well as the gas in the interlocking tube 306 and the transverse column cavity 313, can return to the initial position after each chewing and biting, waiting for the next work to begin, thus ensuring the continuity of the operation of the feedback analysis mechanism 3.

[0078] By using magnet 302 and Hall switch 303, the action of writing pen 317 can be synchronized in the later stage of engagement, effectively enabling writing and recording while the recording paper 312 is wrapped, ensuring the synchronization of operation and recording. Moreover, the synchronization setting is achieved with only two parts, reducing the number of parts in the device and reducing the later maintenance cost.

[0079] Please refer to the above work process. Figures 1 to 4 , Figures 9 to 11 .

[0080] With the adjustable swallowing disorder training device 2, the chewing and biting force during simulated training can be adjusted by adjusting the position of the sliding block 219 on the first adjustment ruler 211 and the second adjustment ruler 213. This is different from and superior to the training devices in the prior art, which only provide a single training force and cannot be adjusted according to different patients at different recovery stages. Moreover, the repetitive training can cause patients to become bored with the rehabilitation simulation exercise, which is not conducive to the patient's recovery. At the same time, with the setting of the feedback analysis device 3, the patient's biting force can be directly fed back. This is different from the current situation where doctors can only make a general judgment on the patient's recovery by asking the patient about the number of bites during exercise and the patient's feelings. There is no clear judgment standard, and it is impossible to provide targeted intervention measures. This is not conducive to developing effective training and medication based on the patient's recovery status, and it can avoid the patient's anxiety, frustration and other psychological problems during the recovery stage, which will affect the rehabilitation effect.
