Description

Pressure loss prevention shaping brace

Technical Field

The invention belongs to the technical field of medical braces, and particularly relates to a pressure loss prevention shaping brace.

Background

The blood supply at the fracture site is the primary motive force for cell proliferation at the fracture site, while the local microenvironment of the fracture has an effect on cell differentiation and phenotype. Small to moderate stresses may promote osteoblast differentiation, while larger stresses may increase osteoblast proportion, promoting fracture healing. However, when a patient walks with a load without the aid of a protective device, the stress at the fracture end cannot be controlled within a safe range, and delayed union, nonunion and even fracture of an internal fixture can be caused. In addition, due to factors such as postoperative pain and psychological adaptation, when a patient is helpless and walks supervised in a hospital or at home after an operation, the compliance is poor, and the training method cannot be repeated. Therefore, after the fracture operation, the load bearing and walking stress stimulation treatment needs to accurately control the stress borne by the fracture end.

In order to better enable fracture patients to recover health, the shaping brace is applied to the field of orthopedic rehabilitation. The shaping brace is an external fixing device which is placed outside the body and aims to limit certain movement of the body so as to assist the effect of surgical treatment, and is directly used for non-surgical treatment. The existing shaping brace can not be well attached to a patient, some parts can not be attached to support, and some parts are easy to be fixed too tightly, so that the problem is solved by using internal-pad gauze or towels generally. The inner pad is made of materials with poor air permeability, and because a patient with fracture needs to wear the shaping brace for a long time, the skin of the patient is easy to be pressed, so that the skin of the patient is red, swollen and damaged.
