Trachea cannula kit capable of obstructing bronchus under guidance of bronchoscope

Abstract

The invention relates to a trachea cannula kit capable of obstructing bronchus under guidance of bronchoscope. The kit comprises an obstruction catheter and a tracheal catheter; the obstruction catheter comprises a catheter body; the front end of the catheter body is provided with a first cuff and a first annular cuff; the tracheal catheter comprises a tracheal catheter body, a first threaded tubeinterface, a second threaded tube interface and a second annular cuff; the front end of the tracheal catheter body is provided with a second cuff; the second annular cuff is disposed on the inner side of the tail end of the tracheal catheter body. The kit has the advantages that while effectively blocking lung bronchus on a diseased side, the kit performs lung ventilation of a healthy side; the tracheal catheter is inserted into trachea without touching bulges at the intersection of the left and right bronchus, and damage stimulation and nerve reflex of the bulges are not caused; the obstruction catheter can be quickly and accurately placed to the bronchus which needs to be blocked under the direct guidance of the bronchoscope.

Description

technical field [0001] The invention relates to the technical field of medical intubation sets, in particular to a tracheal intubation set capable of removing bronchial blockage under the guidance of a bronchoscope. Background technique [0002] At present, one-lung ventilation is a commonly used technique. It is often used for minimally invasive thoracoscopic surgery on one side of the lung or open chest surgery for lung and esophagus. The side lung collapse needs to be opened to expose the surgical space. At the same time, after the bronchus of the affected lung is blocked, some lung lesions on the affected side, especially those involving bronchiectasis, blood, thick phlegm and infectious substances, cannot flow into the healthy lung. While ensuring effective ventilation, the healthy lung can It also serves as an effective physical barrier. After the surgical lesion was removed, double lung ventilation was performed. [0003] At present, a double-lumen endotracheal tube...

AI Technical Summary

Problems solved by technology

However, under the guidance of a fiberoptic bronchoscope, it can effectively block the bronchi of the affected side of the patient's lung and perform ventilation of the healthy side of the lung. The tracheal tube will not damage the patient's lung during the placement process. The prominence between the tubes can be squeezed and stimulated to reduce the patient's bad nerve reflexes, and it can quickly and intuitively determine the position of the blocked catheter during bronchofiberoscopy.
