Bronchus plugging device and plugging method thereof

Abstract

The invention relates to medical instruments, in particular to a bronchus plugging device and a plugging method thereof. The bronchus plugging device comprises a bronchus catheter, wherein a cuff is arranged at the air outlet end of the bronchus catheter; an inflation piston is arranged close to the air inlet end; the inflation piston is connected with the cuff through an inflation pipe; a composite joint is arranged at the air inlet end of the bronchus catheter; the composite joint is of a three-way structure; an upper port of the composite joint is provided with a plugging head, a lower portof the composite joint is connected with the bronchus catheter, a side port of the composite joint is externally connected with a sputum aspirator; and the middle part of the bronchus is provided with a buckle. The bronchus plugging device has the advantages of simple structure, more accurate positioning and more stable positioning, and has better effects of suffocation and deflation in the operation process.

Description

Technical field [0001] The invention relates to medical equipment, in particular to a bronchial occluder and a blocking method thereof. Background technique [0002] In clinical intrathoracic surgery, single-lung ventilation is usually required for surgical anesthesia. This ventilation method can effectively prevent the affected side pulmonary bloody spills or other secretions from entering the contralateral lung, and can separate the contralateral lung from the affected side lung, so that the contralateral lung is not contaminated and kept The clarity of the surgical field during the operation ensures that the operation can proceed smoothly. The traditional one-lung ventilation anesthesia method is a one-lung ventilation method with a double-lumen bronchial catheter inserted. This technology can achieve simultaneous ventilation of both lungs, which can effectively prevent various secretions from overflowing from the affected lung to the contralateral lung. It is more suitable ...

[0003] The existing patent CN 205460314 U discloses a one-time blocking bronchial intubation tube. The syringe connector with a plugging head provided at the upper end of the bronchial tube cannot be sealed. When connecting a sputum suction device during the operation, the operation process is complicated and inconvenient. Sputum suction device connection; the buckle in this application is a single buckle, and the buckle is made of plastic material. During the operation, the buckle and the endotracheal tube are not fixed firmly, and it is easy to shift, which affects the effect of the operation
