Description

Technical Field

[0001] The invention belongs to the technical field of rehabilitation equipment, and in particular relates to a swallowing muscle rehabilitation training device. Background Art

[0002] Swallowing muscle rehabilitation training is an important treatment method for patients with swallowing dysfunction. It aims to improve swallowing function by exercising relevant muscle groups, and avoid the occurrence of difficulties in eating and choking after eating.

[0003] Existing swallowing muscle rehabilitation training devices can provide elastic resistance of different intensities when patients perform mandibular resistance training, achieve the effect of swallowing muscle strength graded training, overcome the functional disorders caused by insufficient swallowing muscle strength, and thus improve the motor function of the swallowing muscle group.

[0004] The existing device has the following shortcomings:

[0005] 1. The base of the existing device is placed on the table through a fixed buckle. This fixing method is not stable enough and is prone to shaking during training, affecting the normal progress of training;

[0006] 2. During the training, the patient places the mandible on the mandibular pad to push the mandibular pad to move and squeeze the elastic part, and uses the elastic force of the elastic part to perform chin contraction resistance rehabilitation training. If the patient lifts the mandible during the training or the mandible and the mandibular pad slip, the elastic part will bounce the mandibular pad away, causing damage to the patient's mandible and neck;

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] 1. The present invention sets a fixing component. When in use, the base is placed on the desktop, the support frame is rotated to be perpendicular to the upper surface of the base and fixed. When the support frame is rotated, the bidirectional screw rotates under the action of the first pulley, the second pulley and the belt, and the slider moves in the direction close to the support frame under the action of the threaded fit, squeezing the air in the cavity out of the cavity, so that negative pressure is generated in the cavity and the conical groove.

The mandible pad drives the fixing block and the sleeve to move toward the fixing rod and squeeze the second spring. At the same time, the buffer in the sleeve is squeezed to the side of the piston close to the fixing rod. When the patient lifts the mandible during training or the mandible and the mandible pad slip, the second spring bounces the fixing block toward the patient. Since the diameter of the conical hole close to the fixing rod is small, the buffer flows slowly toward the fixing block, thereby reducing the speed at which the fixing block bounces toward the patient, thereby avoiding accidental injury to the patient.

[0023] 3. The mandibular pad of the present invention is composed of a plurality of rectangular ceramic plates connected by elastic ropes. When the patient's mandible is placed on the mandibular pad for training, the elastic ropes are stretched to make the ceramic plates more closely fit the shape of the patient's mandible, thereby increasing the contact area between the mandibular pad and the patient's mandible, thereby avoiding partial contact between the patient's mandible and the mandibular pad and causing discomfort to the patient. The ceramic material can also reduce the patient's discomfort during training to a certain extent, and a ventilation component is provided in the fixed block. When the fixed block moves, it drives the fan to rotate and blow air toward the patient's mandible. The patient is not prone to sweating during rehabilitation training, thereby avoiding slipping between the mandible and the mandibular pad caused by sweating. BRIEF DESCRIPTION OF THE DRAWINGS

During training, the patient places the mandible on the mandibular pad 52 and pushes the mandibular pad 52 forward. Under the action of the baffle 512, the fixing block 51 drives the sleeve 62 to move in the direction close to the fixed rod 61 and squeezes the second spring 63. At the same time, the buffer in the sleeve 62 is squeezed to the side of the piston 64 close to the fixed rod 61. When the patient lifts the mandible during training or the mandible and the mandibular pad 52 slip, the second spring 63 bounces the fixing block 51 toward the patient. Since the diameter of the side of the conical hole 65 close to the fixed rod 61 is small, the buffer flows slowly toward the fixed block 51, thereby reducing the speed of the fixing block 51 bouncing toward the patient, thereby avoiding accidental injury to the patient.

[0036] A plurality of ventilation holes 511 are provided on the upper surface of the fixed block 51, a baffle plate 512 is fixed on one side of the upper surface of the fixed block 51 close to the arc plate 5, the mandibular pad 52 comprises a support seat 521 fixed to the upper surface of the fixed block 51, a fixed shaft 522 is fixed on the support seat 521, a movable sleeve 523 is rotatably connected to the fixed shaft 522, the mandibular pad 52 also comprises a plurality of rectangular parallelepiped ceramic plates 524, the plurality of ceramic plates 524 are sequentially connected by elastic ropes 525, both ends of the elastic ropes 525 are fixed on the movable sleeve 523, a ventilation component is provided in the fixed block 51, the ventilation component comprises a through hole 70 provided on the side wall of the fixed block 51 close to the arc plate 5, the ventilation component also comprises a central shaft 71 rotatably connected to the side wall of the fixed block 51, a fan 72 is fixed on one end of the central shaft 71 in the fixed block 51, the end of the central shaft 71 away from the fixed block 51 extends into the fixed rod 61, and the central shaft 71 is connected to the fixed The rod 61 is rotatably connected, a spiral groove 73 is opened on the central axis 71, and a guide rod 74 adapted to the spiral groove 73 is arranged in the fixed rod 61. The mandibular pad 51 is composed of a plurality of rectangular ceramic plates 524 connected in sequence by elastic ropes 525. When the patient's mandible is placed on the mandibular pad 52 for training, the elastic rope 525 is stretched to make the ceramic plate 524 fit the patient's mandible more closely, thereby increasing the contact area between the mandibular pad 52 and the patient's mandible, thereby avoiding partial contact between the patient's mandible and the mandibular pad 52, which may cause discomfort to the patient.

The patient is not easy to sweat during rehabilitation training, thereby avoiding slipping between the mandible and the mandibular pad caused by sweating.

[0037] The present invention can be explained through the following operation mode: when in use, the base 1 is placed on the desktop, the support frame 13 is rotated to be perpendicular to the upper surface of the base 1, and the support rod 14 is fixed in the support frame 13 with screws at a suitable height according to the height of the patient, which is suitable for patients of different heights. When the support frame 13 is rotated, the bidirectional screw 24 rotates under the action of the first pulley 26, the second pulley 27 and the belt, and the slider 25 moves toward the direction close to the support frame 13 under the action of the threaded fit, squeezing the air in the cavity 21 to the outside of the cavity 21, so that negative pressure is generated in the cavity 21 and the conical groove 22, and the base 1 is squeezed on the table under the action of atmospheric pressure, with good fixing effect, no shaking during training, and space saving. During training, the patient places the mandible on the mandible pad 52 and pushes the mandible pad 52 forward. The mandible pad 51 is composed of a plurality of rectangular parallelepiped ceramic plates 524 connected in sequence by elastic ropes 525. When the patient's mandible is placed on the mandible pad 52 for training, the elastic rope 525 stretches to make the ceramic plate 524 fit the patient's mandible more closely, thereby increasing the contact area between the mandible pad 52 and the patient's mandible, thereby avoiding partial contact between the patient's mandible and the mandible pad 52, which may cause discomfort to the patient. The ceramic material can also be used to a certain extent. To reduce the discomfort of the patient, under the action of the baffle 512, the fixed block 51 drives the sleeve 62 to move towards the direction close to the fixed rod 61 and squeezes the second spring 63. At the same time, the buffer in the sleeve 62 is squeezed to the side of the piston 64 close to the fixed rod 61. When the patient lifts his lower jaw during training or the lower jaw and the lower jaw pad 52 slip, the second spring 63 bounces the fixed block 51 toward the patient. Since the diameter of the side of the conical hole 65 close to the fixed rod 61 is small, the buffer flows slowly toward the direction close to the fixed block 51, thereby reducing the speed of the fixed block 51 bouncing toward the patient, avoiding accidental injury to the patient. When the fixed block 51 moves, the guide The central axis 71 drives the fan 72 to rotate with the cooperation of the rod 74 and the threaded groove 73, and the air outside the fixed block 51 is sucked into the fixed block 51 through the through hole 70, and then blown to the patient's mandible from the vent 511. The patient is not easy to sweat during rehabilitation training, and the slipping between the mandible and the mandible pad caused by sweating is avoided. After the training, the training component is removed, the support rod 14 is moved to the support frame 13 and fixed, and then the support frame 13 is rotated to be parallel to the upper surface of the base 1. The air pressure in the cavity 21 and the conical groove 22 increases, the fixation between the base 1 and the desktop is released, and the detachable connection between the training component and the base 1 is convenient for storage.
