Description

a fracture fixator

technical field

The utility model belongs to the field of medical equipment, in particular to a fracture fixer.

Background technique

Fracture refers to the complete or partial break of the continuity of the bone structure. It is more common in children and the elderly, and sometimes occurs in young and middle-aged people. Patients often have a fracture in one part, and a few have multiple fractures. After timely and appropriate treatment, most patients can recover. function, a small number of patients may be left with varying degrees of sequelae.

Existing fracture fixators generally use splints or plaster for external fixation of the fracture site. Gypsum is used for fixation. The weight of the gypsum is relatively heavy. , and the air permeability is poor. The splint is fixed with a bandage, which is troublesome to operate. If the bandage is wrapped too tightly, the patient will feel uncomfortable and affect blood circulation. If the bandage is loosely wound, the splint is easy to slide, affecting the fixation effect. The existing fracture fixator will cause the fracture site to shift again. Although the liner can be used to make up for it, it is not easy to grasp. After the swelling of the fracture site is reduced, the splint is easy to loosen and needs to be fixed again, which is troublesome. The fracture fixer has a relatively fixed width and cannot be adjusted.

Therefore, it is necessary to improve the existing fracture fixer, so that the structure of the fracture fixer is more perfect, the pain of the patient is relieved, and the workload of the medical staff is reduced.

Further, on the flexible fabric is a drug or a cotton pad coated with a drug that has the effects of promoting blood circulation, removing blood stasis, reducing inflammation and relieving pain.

Furthermore, the first layer of flexible fabric, the second layer of plastic fixing plate, and the third layer of skin color outer film are detachable structures.

Further, the width of the curved splint is 3-5cm.

Beneficial effects of the utility model: the side of the arc-shaped splint of the utility model is provided with a rotating shaft, and overlapping arc-shaped splints are arranged on the rotating shaft, so that the width of the fracture fixer can be adjusted as required when performing fracture fixation for fracture patients; The curved splint has a three-layer detachable structure. The plastic fixing plate can effectively prevent secondary damage, and the plastic fixing plate can be reused after disinfection; the second layer of plastic fixing plate is provided with one or more airbags at intervals, and the airbag is connected to one end of the trachea , the other end of the trachea is connected with an inflatable nozzle, which can inflate the airbag at the fracture site according to the needs, so that the fracture fixer can fully fit the fracture site, the effect of fixing the fracture site is good, and it is not easy to shift.
