Description

Technical Field

[0001] The present invention relates to medical equipment, in particular to a medical arm limiting device. Background Art

[0002] At present, most patients with shoulder dislocation need to use an arm sling to prevent the shoulder from dislocating again. However, since the patient's arm is in the recovery period, the limb strength is relatively small, and the current arm sling does not have any fixing device for the patient's palm. If the patient's arm is in the arm sling for a long time, the palm is prone to inward contraction. Over time, the fingers are prone to atrophy and deformation, which is not conducive to the patient's recovery. In addition, the current arm sling is mostly fixed to the patient's neck and shoulder area, which puts a heavy burden on the patient's neck and shoulder area. Summary of the Invention
