Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a hemi-neglect corrector. Background Art

[0002] Ipsilateral neglect, also known as unilateral neglect or unilateral spatial neglect (USN), is one of the most common behavioral cognitive disorders that occur immediately after a stroke. It is characterized by the loss of sensory perception of the contralateral limb, inattention to the contralateral vision, hearing, and touch, and abnormalities in behavioral abilities such as spatial positioning. Since the distribution of human visual-spatial attention is dominant in the right hemisphere, clinically, left-sided spatial neglect caused by right brain damage is common. It not only affects the patient's sensation, movement, cognition, and daily life activities, but also involves mental and psychological activities, and even accidents, such as falling out of bed, falling, and collisions.

[0003] In the clinical work of the rehabilitation medicine department, the patients with more obvious or very severe USN can attract the direct attention of rehabilitation workers. The patients often turn their heads to one side to look at things on the right side. Calls or pain stimulation on the left side can briefly attract the patient's attention or cannot attract the patient's attention. The patient maintains the right side of the neck or trunk rotation position for a long time, resulting in stiffness of the neck and trunk muscles, and at the same time leading to difficulties in rehabilitation training, long rehabilitation cycle, huge rehabilitation costs, difficulties in family care, and extremely poor rehabilitation prognosis. At present, the recognized treatment options for USN include vestibular thermal stimulation, visual movement training, trunk rotation training, transcutaneous nerve point stimulation, prism adaptation training, repeated transcranial magnetic stimulation, etc. However, none of them can extend the treatment to non-training time, and the investment is large and the cost is high. Convenient, low-cost correction devices that can continue rehabilitation for a long time are needed.

[0004] Currently, there are some head-mounted corrective devices, mainly including straps plus side visors and glasses frames plus side visors. They achieve the purpose of treatment and rehabilitation by suppressing the perception (vision, hearing) of the concerned side and increasing the neglect of side vision, hearing and touch. Although they can carry out rehabilitation treatment at low cost and for a long time, the wearer's head is wrapped by the straps for a long time, and the contact area with the head is large, which can easily cause sweating and dermatitis, and the comfort is also poor. When worn, the glasses frame structure is easy to shift or slip when the patient stands up, raises his head, turns his head, etc., thus affecting the treatment effect. In order to suppress the hearing on the concerned side, additional earplugs are needed, and long-term wearing can easily cause discomfort. Utility Model Content
