Fracture of limbs or cervical vertebra of human body, ligament and muscle soft tissue injury, nerve injury or rehabilitation after joint operation all need reasonable treatment means or rehabilitation schemes and the like. The traditional treatment and rehabilitation schemes comprise plaster fixation, splint fixation, high-molecular bandage fixation, external fixation bracket fixation, external fixation brace fixation, internal implant fixation and other series methods.
In the traditional plaster treatment and rehabilitation processes, after plaster of a patient is fixed, observation, follow-up visit and the like are needed, so that the injury such as blood vessel and nerve compression iatrogenic irreversible injury is difficult to find in time, and the plaster needs to be replaced because soft tissue edema of the injured part is easy to change in the treatment and rehabilitation processes, and the risk of fracture re-displacement is easy to occur in the plaster replacement process. In the process of fixing the gypsum, because the gypsum has poor air permeability and can not be cooled for bathing in the process of fixing the gypsum, the intolerable pruritus symptom can be caused by the abnormal cleaning of the metabolism of the skin. The same applies to the traditional splint treatment and the fixation of the polymer bandage.
When the metal external fixing bracket is used, daily medical professional nursing is needed; the external fixing bracket is difficult to bath in the treatment process and is limited in daily dressing; if the metal external fixing bracket is used for treating the loosening or the breakage of the metal spicule, the risk of iatrogenic nerve and blood vessel injury and the like can occur. In using internal fixation implant devices, anesthesia is required, subject to the surgical field, expensive internal implant devices, implant failure, and the like.
The human body has very strong self-repairing capability, when a good environment is created for the body, the fracture healing of the human body, the self-repairing of ligament injury and the braking rehabilitation treatment after partial operation can achieve good effects, and the treatment and the rehabilitation can be realized by the traditional plaster splint technology without the closed injury of the joint surface and the epiphyseal plate epiphyseal line.
In view of the defects of the traditional plaster splint fixation, the high molecular bandage fixation, the movable external fixation brace, the metal external fixation bracket, the implant operation treatment and the like, such as the wrapped trunk is not ventilated and ventilated; failure to clean if basic cleaning is acceptable; the condition of the inner trunk can not be observed in real time when the bag is wrapped, and the skin metabolism is easily influenced; daily dressing is limited; in the case of secondary damage to the trunk during fixing or replacing the fixture, a trunk fixing solution solving the above problems is needed.
