Description

A Wedge Locking Portable Life Support System with Fracture Fixation Function

technical field

The invention belongs to the field of medical equipment, and in particular designs a wedge-shaped locking portable life support system with fracture fixation function.

Background technique

Relevant data show that the wounded on the battlefield can be given on-site first aid, transported, and evacuated to the hospital within the "golden time", which can effectively reduce the death rate of the wounded. At present, various medical equipment occupy a lot of space in the process of treating and transferring large-scale casualties, and cannot treat more patients. Moreover, the first aid equipment is bulky, and the oxygen supply time of the compressed oxygen cylinder is short, which is also dangerous. In the process of on-site first aid on the battlefield, the installation of first aid equipment is complicated and takes a long time.

Fractures and bone injuries are a common type of injury on the battlefield. Fast fixation of the fractures of the injured can avoid secondary damage to the fractures during the transfer process and reduce the pain of the wounded.

CN101524306B discloses a portable life support system, which is composed of emergency medical equipment such as oxygen cylinders, ventilators, suction devices, monitors, infusion pumps, and comprehensive treatment bags. Support function. But its portable life support system is installed directly above the wounded, which is not conducive to the transfer of the wounded.
