Technical Field

[0002] For burn patients, after the wound heals, severe scar hyperplasia leads to abnormal appearance and function, causing serious difficulties in life and psychological pressure on the patients. In particular, necrosis often leads to serious psychological problems and developmental difficulties for children. Among them, scar hyperplasia after burns on the hands is the most common and serious type of scar hyperplasia. Many patients with severe hand burns often have inadequate recovery after surgery, resulting in hand function impairment, impaired living ability, and even secondary scar surgery. When the patient / child is discharged from the hospital, the doctor will repeatedly instruct the patient / patient's family to strengthen rehabilitation treatment and go to the hospital for regular follow-up visits.
[0003] However, patients often have poor compliance. Once the scar proliferates excessively, the effect of rehabilitation treatment will be much worse than before, especially the rehabilitation exercises of hand function. Because the proliferation of scars is slow but stable, it often takes 1-2 weeks for a small functional decline to be visible to the naked eye, and 1-2 months for more obvious functional impairment to appear. Patients / children's families often tend to ignore this functional change. Utility Model Content
