Description

Injection molding type fracture and limb fracture fixing device

Technical Field

The invention relates to an injection molding type fracture and limb breakage fixing device and a fixing method thereof, belonging to the field.

Background

The plaster is mainly used for effectively fixing the bone part after fracture and preventing the fracture problem from aggravating due to the fact that the later stage is impacted by external force, so that the plaster is used on the two points, and the bone can be effectively healed better. Most patients after fracture will go through the process of plaster-applying, and the plaster-applying function is mainly to effectively fix the part with the fracture. After all, careless displacement or secondary influence on the bone part can be prevented in the process of plaster application, so that the problem of displacement of the fracture position can be better prevented in the aspect of plaster application after fracture, and a function of overall fixation can be achieved. The plaster bandage is made by spreading fine powder of plaster on special gauze bandage and curling. When in use, the plaster bandage is immersed in water, and the anhydrous calcium sulfate gradually becomes firm after absorbing water, thereby playing an effective external fixation role on the fracture. The application of plaster in fracture cases is common.

After plaster is applied, the plaster cannot be removed before the fracture is healed, but plaster application and fixation usually take 2-3 months, skin sensitive people cause skin itching and are very difficult to suffer due to the fact that the plaster is not breathable, and skin ulcer and necrosis can be caused seriously. When plaster is applied, the plaster bandage is usually put into water to make the plaster powder fully absorb water, then the plaster bandage is quickly wound on the affected limb for 8-12 circles, and the plaster can be shaped after fixation to fix the affected limb. However, each winding needs to be moved and touched to the affected limb, which can cause pain to the patient and can cause dislocation of the original broken bone in severe cases. Winding the plaster bandage is also very cumbersome to operate, can consume a large amount of time, and is inefficient.
