Problems solved by technology

The current tracheotomy devices are all operated by doctors and nurses. Before the arrival of paramedics or medical personnel on the battlefield or accident scene, the lives of the injured must be quickly rescued within 2 to 4 minutes. It is necessary to design a rapid tracheotomy device. open the device and be completed by non-medical personnel
It is difficult for non-medical staff to perform tracheal puncture directly in the neck. Improper piercing can easily damage the large blood vessels on both sides and cause excessive bleeding in the thyroid gland.

Abstract

A reverse guide tube for intercricocentesis is composed of a tubular arc main body and a handle linked to the rear end of said main body and with horizontal wings. Said main body has a closed front tip end with tangent guide slot, an air inlet hole close to tip end, and the length graduation lines and vector lines close to handle. A pair of opening pliers for said reverse guide tube is also disclosed, which has a curved surface matched with said guide slot of reverse guide tube and a cutting edge.

Description

technical field [0001] The invention relates to a medical device, in particular to a tracheotomy guide tube and a spreading forceps matched with it. Background technique [0002] In battlefields and some accident sites, the injured will suffer from airway obstruction and suffocation. At this time, every second must be counted for rescue, because the heart will stop beating within 2 to 4 minutes of suffocation, and the brain will undergo irreversible degeneration. The current tracheotomy devices are all operated by doctors and nurses. Before the arrival of paramedics or medical personnel on the battlefield or accident scene, the lives of the injured must be quickly rescued within 2 to 4 minutes. It is necessary to design a rapid tracheotomy device. Do not open the device and complete the operation by non-medical personnel. It is difficult for non-medical personnel to perform tracheal puncture directly in the neck. Improper piercing can easily damage the large blood vessels o...
