Description

Technical Field

[0001] The invention relates to the technical field of training devices, and in particular to a training device for upper limbs of Parkinson's disease patients. Background Art

[0002] Parkinson's disease is a common neurodegenerative disease that mainly affects middle-aged and elderly people. Symptoms of the disease include resting tremor, muscle rigidity, bradykinesia and postural balance disorders. Treatments include medication, surgery and rehabilitation training.

[0003] The rehabilitation training device in the prior art cannot perform enhanced training on the patient's hands, and therefore cannot properly relieve the discomfort of the hands of Parkinson's patients. Based on these problems, Chinese patent CN217611902U discloses a training device for alleviating tremor in the upper limbs of Parkinson's patients. The patient sits on a chair and places both hands on the support plates on the two training mechanisms respectively, and the palms are placed on the massage rod. The support plate is driven by the driving component to perform reciprocating swinging motion around the vertical rod, thereby driving the patient's hands to swing. When the support plate is swinging, the bottom end of the massage rod intermittently contacts the ball, so that the massage rod slides along the perforation, so that the top end of the massage rod performs intermittent contact massage on the palm. When the patient is training, the upper limbs are kept in a swinging state, and the massage rod performs intermittent contact massage on the palm, so as to properly relieve the discomfort of the hands of Parkinson's patients.

[0004] Since each patient's physical characteristics, especially height and arm length, vary significantly, this diversity makes them face different needs when using the rehabilitation training device. However, the training device has a significant limitation in design. The height of its support plate is fixed and cannot be adjusted. This fixed height setting cannot adapt to the specific needs of different patients, resulting in them being unable to adjust the support plate to a suitable and comfortable height according to their physical conditions during use so that their hands can be placed naturally and comfortably on it for training. This design defect not only affects the patient's user experience, but may also have a negative impact on the rehabilitation effect, because the uncomfortable hand placement posture may cause the patient to be unable to maintain the correct posture during training, thereby affecting the training effect.

[0025] (1) By setting a placement plate, the patient's arm can be placed. When the shaft core disk is rotated, the threaded column will also rotate together. At this time, the slider will move up and down on the outer wall of the rotating threaded column. At the same time, the table and the placement plate above will also move up and down together, thereby adjusting the placement height of the patient's arm. By setting a connection structure between the toothed block and the gear bar, the slider can be fixed to prevent the slider from sliding downward. By using the pulling plate, the gear bar on the first spring column can be pulled to allow the gear teeth on the gear bar to detach from the toothed block.

The top surfaces of the seat frame, the mesh seat cushion cover and the mesh plate are all provided as inclined surfaces. At this time, the patient will not slip out of the training device when sitting on the mesh seat cushion cover. When the battery box is turned on, the T-shaped wire can be used to transmit electrical energy to the intake fan and the exhaust fan at the same time. At this time, the intake fan can transport the outside air to the seat frame, and the exhaust fan can quickly discharge the heat in the seat frame. This can not only improve the comfort of the patient during regular sitting in hot weather, but also improve the practicality of the entire training device.

[0028] (4) When the motor drives the hollow square tube to rotate, the slide bar on the second rotating shaft at the top of the perforating rod will slide back and forth in the inner wall of the second slide groove, and at the same time drive the placement plate to swing back and forth, thereby realizing the training of the patient's upper limbs. By setting a connecting structure between the insertion tube and the through hole, the perforating rod and the hollow square tube can be fixed together. By pulling the perforating rod, the length of the perforating rod extending out of the hollow square tube can be adjusted. At this time, the sliding range of the slide bar can be changed, thereby realizing the adjustment of the shaking amplitude of the placement plate and meeting the needs of the patient.
