Off-line system under oxygen therapy mode of patient suffering from tracheal intubation

Abstract

The invention relates to the technical field of tracheal intubation equipment and relates to an off-line system under an oxygen therapy mode of a patient suffering from tracheal intubation. The systemcomprises an intubation cannula, a threaded pipe, a Y-shaped joint, an air return pipeline, an air supply pipeline and a breathing machine. One end of the intubation cannula is communicated with thethreaded pipe through an L-shaped joint, one end of the threaded pipe is communicated with one end of the Y-shaped joint, two openings in the end, away from the threaded pipe, of the Y-shaped joint are connected to the air return pipeline and the air supply pipeline respectively, water accumulation devices are arranged in the middle of the air return pipeline and the middle of the air supply pipeline respectively, one end of the air return pipeline is connected to an air return end of a respirator, and one end of the air supply pipeline is connected to an air supply end of the respirator. By means of the design, off-line operation can be completed under the condition that a breathing circuit is not disconnected, a patient continuously inhales heated and humidified gas in the off-line process so that stimulation of the gas to the patient is avoided, and a disposable oxygen inhalation device does not need to be additionally used so that operation time is saved and hospitalization expenses are saved.

Description

technical field [0001] The invention relates to the technical field of endotracheal intubation equipment, in particular to an off-line system in oxygen therapy mode for endotracheal intubation patients. Background technique [0002] Patients with mechanical ventilation with tracheal intubation must be off-line before the ventilator is stopped and the trachea is removed; the conventional off-line plan in the past was to install a disposable oxygen inhalation device and connect the end of the oxygen inhalation tube with a skin needle (cut off the steel needle). ), adjust the oxygen flow to the required flow rate, separate the ventilator from the tracheal intubation, and put the scalp needle into the tracheal intubation to supply oxygen to the patient. The conventional off-line scheme is simple to operate, but the oxygen inhaled by the patient is a wet and cold gas, and it is directly blown into the lungs, which greatly stimulates the patient and requires an additional oxygen i...

AI Technical Summary

Problems solved by technology

The conventional off-line solution is simple to operate, but the oxygen inhaled by the patient is wet and cold gas, and it is blown directly into the lungs, which is very irritating to the patient. At the same time, an additional oxygen inhalation device needs to be turned on, which increases the cost and takes a long time to operate.
