Description

Double-cavity bronchial catheter with local anesthesia function

Technical Field

The utility model belongs to the technical field of medical instrument, especially, relate to a two-chamber bronchial tube with local anesthesia function.

Background

The double-cavity bronchial catheter is mainly used for lung isolation operation, separates the left and right lung ventilation paths of a patient and can selectively ventilate a single lung. When in use, the double-cavity bronchial catheter is inserted into the main bronchus of a patient to temporarily isolate the ventilation of the left and right bronchial systems, so that anesthetic gas can be inhaled into one or two side lumens to ensure that the patient can take general anesthesia, and convenience is provided for lung surgery and other operations. Because the intubation position of the bronchus is deep, when the patient is changed from the general anesthesia state to the awakening state, stress reactions such as cough and the like are easy to occur because the trachea is provided with the catheter, and when the bronchus is used for local anesthesia, liquid drops are large and are directly dripped into the inner wall of the trachea, the patient is easy to be choked.

For this reason, the patent numbers are: chinese patent CN204543233U, "a two-chamber bronchial tube with local anesthesia function", includes main endotracheal tube, is provided with bronchial tube on main endotracheal tube's the outer wall, is provided with first gas tube and first atomizing pipe on the main endotracheal tube, is provided with second atomizing pipe and second gas tube in bronchial tube's the lateral wall, and first atomizing pipe forms first atomizing circle at main endotracheal tube lower extreme, and second atomizing pipe forms second atomizing circle at bronchial tube lower extreme, is provided with a plurality of apertures on the atomizing circle. This patent is through local anesthetic in first atomizing circle and second atomizing circle be vaporific spray on bronchus and main trachea wall, can play the local anesthesia effect, slow down the discomfort that the patient caused because of the trachea cannula is amazing, nevertheless this patent also has following defect simultaneously:

1. the double lumen bronchial catheter has too many hoses, such as: first atomizing pipe, second atomizing pipe, first gas tube, second gas tube etc. the hose is mixed and disorderly, and easy knotting is difficult for the arrangement.

2. Every time, the first air bag and the second air bag are respectively inflated, and the first atomizing ring and the second atomizing ring are respectively injected, so that the operation is troublesome, and the working efficiency is low.
