Description

Technical Field

[0001] The utility model belongs to the technical field of shoulder straps, and in particular relates to an adjustable shoulder strap. Background Art

[0002] In surgical clinics, we often encounter patients who need their arms suspended. These patients have swollen arms, broken arms, fractured arms, and other problems. In order to avoid moving their arms, they usually need to suspend their arms to avoid insufficient blood supply caused by exerting force or sagging their arms. They need to use an arm suspension frame in combination with a shoulder strap for support.

[0003] When the existing shoulder strap is used with the arm suspension frame, since the arm length of each person is different, the length of the shoulder strap needs to be adjusted according to the use requirements. However, when adjusting the existing shoulder strap, the shoulder strap is generally pulled repeatedly and the limit adjustment is performed through the buckle. This adjustment method is more troublesome to operate and is not convenient enough. For this reason, we propose an adjustable shoulder strap. Utility Model Content
