Description

Technical Field

[0001] The utility model belongs to the technical field of tongue muscle training, and in particular relates to a tongue retraction muscle strength evaluation and feedback training device. Background Art

[0002] Swallowing disorders can develop during the course of many diseases, including cerebrovascular disease, brain trauma, neurological disorders, and aging. Swallowing disorders can lead to adverse consequences such as malnutrition, dehydration, aspiration, and aspiration pneumonia. Therefore, swallowing training is crucial for improving the safety and effectiveness of oral intake and clinical outcomes. Many patients with swallowing disorders experience weakened tongue base retraction during swallowing, resulting in insufficient pharyngeal pressure. Tongue base retraction is considered the primary source of positive pressure on the tail end of the food bolus and plays a crucial role in pharyngeal bolus clearance. Furthermore, posterior tongue movement promotes epiglottic rotation and medial and anterior movement of the arytenoid cartilages, protecting the laryngeal vestibule entrance and preventing food from being aspirated into the airway. Therefore, tongue base retraction is also considered a mechanism of airway protection. When the tongue base retracts, it abuts the forward-moving posterior pharyngeal wall, increasing pharyngeal pressure and accelerating bolus propulsion. Insufficient tongue base retraction in patients with swallowing disorders can lead to food retention and aspiration. Therefore, patients with dysphagia usually undergo rehabilitation training at the root of the tongue.

[0003] Currently, tongue sandwich training (pulling the tongue back to swallow) and tongue retraction training are performed on patients with dysphagia. The therapist still uses the technique of pulling the patient's tongue outward to practice the strength of tongue retraction. When using it, there are problems such as:

[0004] 1. It is impossible to quantify and evaluate the tongue retraction strength of patients, unable to reflect the changes in tongue retraction strength before and after training, and unable to compare tongue retraction strength between different patients, making it difficult to achieve standardization;

[0005] 2. On the other hand, when using the above device, the amount of traction applied to the patient is based on the therapist's subjective feeling. It is difficult to apply the appropriate traction force according to the patient's actual tongue retraction strength, and it is impossible to achieve fine adjustment of different resistance forces.

[0006] 3. In addition, the traditional clinical training process requires the therapist to guide the patient, provide resistance to tongue muscle stretching, and give verbal prompts and encouragement to the patient. The training process is relatively boring and monotonous, which not only increases the clinical workload of medical staff, but also makes it difficult to mobilize the enthusiasm of patients, affecting the training effect.

[0007] Therefore, the present invention proposes a tongue retraction muscle strength assessment and feedback trainer to solve the problems existing in the above-mentioned prior art. Utility Model Content

The top end of the spring 42 is fixedly connected to the bottom of the adjustment frame 4, and a positioning rod 43 is slidably connected to the front end of the adjustment frame 4, and the surface of the positioning rod is clamped in the limit block 44.

[0056] In this embodiment, the elastic force of the spring 42 pushes the limit block 44 to be engaged in the corresponding limit groove 45, thereby limiting the winding wheel 46. At this time, the positioning rod 43 is pushed to move at the front end of the adjustment frame 4 and be engaged in the limit block 44, so that the limit block 44 is stably engaged in the corresponding limit groove 45.

[0057] When using this tongue retraction muscle strength assessment and feedback trainer to train the patient's tongue muscles:

[0058] The winding wheel 46 is turned to adjust the appropriate length of the pull rope 3 and lock the winding wheel 46. When the length of the pull rope 3 is extended, the tension is reduced, and the resistance of the patient's tongue retraction can be reduced. When the length of the pull rope 3 is shortened, the tension is increased, and the resistance of the patient's tongue retraction can be increased. After adjusting the appropriate pulling force for the patient's tongue, the power of the smart display 22, the tension sensor 5 and the controller 8 is manually turned on, and the game mode training program is displayed on the smart display 22. At this time, the tongue suction cover 1 is placed on the patient's tongue, and the power switch on the micro air pump 6 is manually pressed. The micro air pump 6 works and extracts the air in the tongue suction cover 1, so that the tongue suction cover 1 is negatively adsorbed on the patient's tongue by negative pressure. The micro air pump 6 is manually turned off. At this time, the patient's tongue retracts, pulling the tongue suction cover 1, the sliding frame 76 and the pull rope 3 to move. The specific force of the tongue pulling is transmitted to the smart display 22 through the tension sensor 5 and the controller 8. The smart display 22 provides feedback to the patient and staff through video and sound, thereby mobilizing the patient's enthusiasm for training. The smart display 22 can also evaluate and statistically display the data during the patient's training process. After the training is completed, the power of the intelligent display 22, the controller 8 and the tension sensor 5 is turned off, and the tongue suction cover 1 and the micro air pump 6 are disassembled to disinfect the tongue suction cover 1.

[0059] When the tongue retraction muscle strength assessment and feedback training device of the utility model is used:

[0060] The winding wheel 46 is rotated to adjust the appropriate length of the pull rope 3. The elastic force of the spring 42 pushes the limit block 44 to be clamped in the corresponding limit groove 45, limiting the winding wheel 46 and pushing the positioning rod 43 to be clamped in the limit block 44, so that the limit block 44 is stably clamped in the corresponding limit groove 45. The appropriate pulling force of the patient's tongue is adjusted, and the power of the smart display 22, the tension sensor 5 and the controller 8 is manually turned on. The training program of the game mode is displayed on the smart display 22. At this time, the tongue suction cover 1 is placed on the patient's tongue, and the air in the tongue suction cover 1 is extracted by the micro air pump 6 so that the tongue suction cover 1 is negatively adsorbed on the patient's tongue. At this time, the patient's tongue retracts, pulling the tongue suction cover 1, the sliding frame 76 and the pull rope 3 to move. The specific force of the tongue pulling is transmitted to the smart display 22 through the tension sensor 5 and the controller 8. The smart display 22 provides feedback to the patient and staff through video and sound, thereby mobilizing the patient's enthusiasm for training and the smart display 22 can evaluate and statistically display the data during the patient's training process.

[0061] It should be noted that the tongue suction cover 1, smart display 22, controller 8, tension sensor 5, micro air pump 6, etc. in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the smart display 22, controller 8, tension sensor 5 and micro air pump 6 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.
