Description

Technical Field

[0001] This invention relates to the field of medical rehabilitation training devices, and more specifically, to an auxiliary device for rehabilitation training of patients with cerebral infarction in the neurology department. Background Technology

[0002] Post-stroke sequelae refer to the sequelae that may occur one year after the onset of cerebral infarction, manifested as hemiplegia, speech disorders, or facial paralysis. Experimental and clinical studies have shown that due to the plasticity of the central nervous system, there is a possibility of functional reconstruction during the recovery process after brain injury. Rehabilitation training refers to physical activities that are beneficial to the recovery or improvement of function after injury. Appropriate and scientific physical exercises have a positive effect on the rapid healing of injuries and the promotion of functional recovery.

[0003] Existing training aids for stroke patients, such as application number CN202110237316.2, include devices that can assist brain injury patients in walking rehabilitation training. These devices are safe and reliable, allowing brain injury patients to accumulate balance experience through falls without sustaining injuries. This shortens the time it takes for brain injury patients to walk independently and improves the effectiveness of walking rehabilitation training. The device can automatically assist patients who have fallen and also provide a certain amount of pulling force to help them walk, reducing the workload of medical personnel. By gradually reducing the upward pulling force applied to brain injury patients, the device can ultimately help them walk independently.

[0004] However, existing rehabilitation training devices can only perform leg training, lacking hand training, and require staff assistance throughout the training process, which greatly increases labor and training costs, making them difficult for patients with limited financial resources to use.

A circular inner cavity is located inside the upper and lower ends of the seat, with equidistant toothed grooves on its inner circumference. Teeth are also located on the upper outer side of the drive rod, engaging with the inner side of the circular inner cavity. When the drive rod contacts the raised teeth, it rotates using the engagement on one side, which in turn rotates the upper part of the seat. This allows the device to rotate when the patient moves to one end of the device base. The automatic rotation to another direction is achieved by installing a drive rod in a movable cavity located under the seat. The movable cavity is elliptical in shape, with its length matching the diameter of the circular inner cavity. A top block, shaped like a right-angled trapezoid, is installed near the toothed end of the limiting slide. A spring is installed on one side of each top block. An integrally formed flange, annular in shape, is located on the outer side of the lower part of the drive rod. The movable cavity has an elliptical limiting groove corresponding to the height of the flange. This allows the drive rod to contact the inclined surface of the top block after rotating the upper part of the seat. While compressing the spring, the top block compresses the spring, and when the rod moves to the notch in the partition, it is driven to the other side. The process is repeated on the other side, allowing the upper part of the seat to automatically rotate as the seat moves. Attached image description:
