First-aid binding tool for arm fracture

Abstract

The invention relates to the technical field of first-aid tools, and particularly relates to a first-aid binding tool for arm fracture. The first-aid binding tool for arm fracture comprises a lower arm plate, wherein a upper arm plate is movably arranged above the lower arm plate through a movable hinge, binding bands are fixedly connected on the lower arm plate and the upper arm plate, bottom plates are fixedly arranged on the binding bands, a telescopic pad is fixedly connected on the bottom plates, assembly parts are hinged on the lower arm plate and the upper arm plate, slots are arrangedin the assembly parts, fixing shafts are fixedly arranged on the assembly parts, torsional springs are fixedly connected on the fixing shafts, rotating rods are rotatably arranged on the fixing shafts, sliding grooves are formed in the rotating rods, and sliding blocks are slidably connected in the sliding grooves; the binding tool is composed of two hinged parts, and is divided into a lower-arm fixing part and a upper-arm fixing part, and the angle between the lower arm plate and the upper arm plate can be adjusted by rotating a nut sleeve, thus making the lower arm plate and the upper arm plate perfectly fitted to an injured part of a patient for fixation, so as to guarantee the first aid effect.

Description

technical field [0001] The invention relates to the technical field of first aid equipment, in particular to a binding tool for arm fracture first aid. Background technique [0002] Trauma is one of the three major disease burdens that endanger human health, and its prevention and control have received more and more attention from all over the world. Extremity injuries accounted for a relatively high proportion of injury sites in trauma patients, and extremity fractures were more common. Early reduction and fixation of the fracture is beneficial to effectively control the bleeding of the fracture end. The stability of the fracture can reduce the pain of the patient, avoid the movement between the broken ends to stimulate blood vessel and nerve damage, and can effectively reduce the incidence of serious complications such as fat embolism and acute respiratory distress syndrome. Arm fracture is a relatively common situation in people's life. Nowadays, splints and straps are c...

Problems solved by technology

Arm fracture is a relatively common situation in people's life. Nowadays, splints and straps are commonly used to fix people's traumatic parts. There are often many angles between the upper arm and the forearm when the arm is fractured, and the patient's arm cannot be easily changed, so it is very inconvenient to use. At the same time, when the one-piece structure is bent, the flexible material at the bending part is prone to accumulation. In view of the injury caused by the affected part of the patient, we propose a binding tool for arm fracture first aid
