Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a rehabilitation chair for neurology. Background Art

[0002] Neurology is a secondary discipline related to nerves, mainly treating cerebrovascular diseases, such as cerebral hemorrhage, cerebral infarction, migraine, encephalitis, myelitis, dementia and other diseases; neurology patients suffer from impaired leg function due to long-term bed rest, and will have symptoms of mobility problems and limb weakness, so they need to do leg exercises regularly to avoid muscle atrophy. Existing rehabilitation chairs cannot stretch and expand the legs well during leg exercises, and most of them simply swing and lift the patient's legs at the same frequency, resulting in poor exercise effects. In addition, when patients sit on traditional rehabilitation chairs for a long time, their waists are empty, and they will experience back pain after the leg exercises. Utility Model Content

[0008] The utility model is further configured as follows: corresponding foot support plates are respectively installed at the lower ends of a pair of leg support plates.

[0009] The utility model is further configured as follows: the pillow is a soft pillow.

[0010] The utility model is further configured as follows: upper sides of a pair of leg support plates are both arc-shaped grooves.

[0011] The utility model is further configured as follows: the motor is a speed-adjustable motor.

[0012] The beneficial technical effect of the utility model is as follows: the utility model helps the patient to the upper side of the chair body, places the patient's calves on the corresponding leg support plates, adjusts the position of the pillow to put the patient in a comfortable state, and avoids the patient's waist being in a sore state during subsequent leg exercises, starts the motor, and adjusts the motor speed according to the patient's condition. If the patient's leg function is seriously impaired, the speed is adjusted to a slow speed. A pair of discs drive the corresponding connecting rods to swing back and forth through the corresponding support rods, and a pair of connecting rods drive the corresponding leg support plates to swing back and forth. Since the pair of connecting rods are at the farthest relative distance, the pair of leg support plates swing in opposite directions, so that the patient's legs swing back and forth, simulating the crossed swinging of the legs when walking, and comprehensively stretching and expanding the calf muscles.

[0016] Please refer to the attached Figure 1-Figure 2 Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0017] The utility model proposes a rehabilitation chair for neurology. When using the device, the patient is supported onto the chair body 1, the patient's back is leaned against the chair back, the patient's two calves are placed on the corresponding leg support plates 9, the patient's feet are placed on the corresponding foot support plates, and the turntable is turned. The turntable drives the lead screw 3 to rotate, and the lead screw 3 drives the slider 4 to slide upward along the slide groove, and the slider 4 drives the pillow 2 to slide upward. When the pillow 2 slides to the patient's waist position, the turntable is stopped, which is convenient for patients of different heights to cushion their waists, so that the patient is in a comfortable state and avoids the patient's waist from being in a sore state during subsequent leg exercises. If the patient's legs are very stiff, the patient's legs are lightly tied to the corresponding leg support plates 9 by straps to ensure that the patient's legs can swing with the leg support plates 9, and there is no need to tie them tightly to cause marks on the patient's legs (if the patient's legs have a certain degree of flexibility, they can be directly placed on the leg support plates 9). The speed of the motor 11 is set according to the patient's condition. If it is a relatively stiff situation, Then the motor 11 is adjusted to a slow speed so that the patient's legs can gradually adapt to the state of activity (conversely, if the patient's legs have a certain degree of flexibility, it can be adjusted to a slightly faster speed to promote the patient to gradually adapt to the state of leg activity), start the motor 11, the motor 11 drives the corresponding gear 6 to rotate, one gear 6 drives the gear 6 meshing with it to rotate, one gear 6 drives a pair of discs 7 to rotate, the pair of discs 7 drives the corresponding connecting rods 8 to swing, and the pair of connecting rods 8 drives the corresponding leg support plates 9 to swing. Since the pair of connecting rods 8 are located at the position with the farthest relative distance (i.e., the two ends of the disc), the pair of leg support plates 9 drive the patient's corresponding calves to swing back and forth, simulating the cross-swinging of the legs when walking, and comprehensively stretching and expanding the calf muscles. When the patient's legs have been exercised for a certain period of time, the motor 11 is turned off, and the patient can be helped down from the chair body 1. The swinging speed of the pair of leg support plates 9 shall not exceed the walking frequency of a normal person. When the patient's legs have adapted to the rehabilitation chair, they can be moved to the standing rehabilitation device for subsequent intensive training.
