AI Technical Summary

Technical Problem

Existing rehabilitation devices for shoulder subluxation cannot provide precise lifting force, easily compress nerves and blood vessels in the armpit, leading to skin damage and movement restriction, and cannot independently regulate specific muscle groups.

Method used

A suction reduction device for shoulder subluxation was designed. It uses a suction cup to fit and connect with the supraspinatus and deltoid muscles. The suction adjustment component provides a precise upward traction force to avoid compression of surrounding tissues, and the length adjustment component can be adapted to the needs of different patients.

Benefits of technology

It achieves safe and comfortable dynamic repositioning, precisely targeting key muscle groups, avoiding skin damage and nerve compression, providing continuous and uniform repositioning force, and promoting neural pathway remodeling.
