Double-lumen bronchial intubation

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a double-lumen bronchial intubation which comprises a double-lumen catheter with one end serving as a patient end and the other end serving as a mechanical end, an air bag arranged at the patient end of the double-lumen catheter and a three-way connecting tube connected to the mechanical end of the double-lumen catheter, the double-lumen catheter comprises a left catheter and a right catheter, identification stickers used for distinguishing the left catheter from the right catheter are arranged near the mechanical ends of the left catheter and the right catheter respectively, a one-way valve is arranged at the joint of the left catheter and the right catheter of the double-lumen catheter and located near the mechanical end of the double-lumen catheter, and the one-way valve is provided with a left atomization connector in one-way communication with the left catheter and an atomization connector in one-way connection with the right catheter. The double-lumen bronchial intubation has the advantages that automatic timing can be achieved after airflow is blocked, timing is accurate, the workload of workers is reduced, oxygen can be supplied to a patient through ventilation, atomization can be conducted on the patient at the same time, and lung dryness is avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a double-lumen bronchial intubation tube. Background technique [0002] Endotracheal intubation is to insert a special endotracheal tube into the patient's trachea through the mouth. This device and technology can provide the best conditions for airway patency, ventilation and oxygen supply, respiratory tract suction and prevention of aspiration. Intratracheal anesthesia and the technique of rescuing patients are also an important measure for rescuing patients with cardiac and respiratory arrest. It facilitates the removal of respiratory secretions, maintains the patency of the trachea, reduces airway resistance, helps reduce the anatomical dead space of the respiratory tract, ensures effective ventilation, and provides conditions for oxygen pressurization artificial respiration and intratracheal administration. Therefore, patients who have respiratory arrest or respirat...

AI Technical Summary

Problems solved by technology

The existing double-lumen bronchial intubation tube is generally connected with a ventilator for ventilation and oxygen supply for patients, and has a single function

The left and right tubes of the double-lumen bronchus are marked with different colors to distinguish them, which can easily be mistaken by medical staff

When the double bronchus is connected to the ventilator, the air supply time generally does not exceed 40 minutes. If the time is too long, it will affect the lung function. Therefore, the air flow should be blocked regularly. Generally, the medical staff clamps the pipe that needs to stop the ventilation with pliers. And carry out manual timing. On the one hand, manual timing is easy to miss the time and the timing is inaccurate. On the other hand, it increases the workload of medical staff.
