technical field

The invention relates to medical instruments, in particular to a medical arm limiting device.

Background technique

At present, most patients with shoulder dislocation need to use an arm sling to prevent the shoulder joint from dislocating again. However, because the patient's arm is in the recovery period, the limb strength is small, and the current arm sling does not have any fixation device for the patient's palm. When the arm is in the arm sling for a long time, it is very easy to cause the palm to contract inward. If it goes on for a long time, the fingers are easily atrophied and deformed, which is not conducive to the recovery of the patient. Most of the current arm slings are fixed with the patient's neck and shoulders. It causes a greater burden on the patient's neck and shoulders.
