Bronchial occlusive device capable of monitoring intrapulmonic pressure

Abstract

The invention discloses a bronchial occlusive device capable of monitoring intrapulmonic pressure. The bronchial occlusive device is characterized by comprising a connector and a suction tube, whereinan occluding air bag is arranged at one end of the suction tube; the other end of the suction tube is connected with a pressure sensor; a Y-shaped joint is arranged on the suction tube in a sleevingmanner; an inflating air bag matched with the occluding air bag is arranged on the Y-shaped joint; a check valve is arranged at one end of the inflating air bag; one end of the pressure sensor is provided with a venous transfusion connection port and a monitor connection port; the other end of the pressure sensor is provided with a three-way valve exhaust valve; the pressure sensor is connected with the suction tube through a pressure measurement connection tube; the pressure measurement connection tube is connected with the suction tube through a Luer taper. The bronchial occlusive device disclosed by the invention has the advantages that the collapse degree of the intrathoracic lung before thoracotomy is dynamically estimated by monitoring the intrapulmonic pressure, and the problem of long lung collapse time of the bronchial occlusive device is solved; the lung collapse degree is precisely estimated by monitoring the intrapulmonic pressure, and a thoracoscope is accurately guided into the chest.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bronchial occluder capable of monitoring intrapulmonary pressure. Background technique [0002] The bronchial occluder is used for lung isolation during one-lung ventilation in thoracic surgery. The conventional lung atrophy mode of the bronchial occluder is "lung atrophy after thoracotomy", that is, after the pleura is opened, the blocked side lung begins to shrink gradually. Surgery can only be performed after the atrophy is complete, wasting a lot of waiting time. Therefore, its main disadvantage is that the lung atrophy on the occluded side takes a long time, which delays the start of the operation and increases the risk of the operation. Therefore, there is an urgent need to change the lung shrinkage technique to accelerate the lung shrinkage rate of the bronchial occluder. [0003] According to the main mechanism of lung atrophy, that is, the principle of absorp...

AI Technical Summary

Problems solved by technology

However, "lung atrophy before thoracotomy" cannot visually assess the degree of lung atrophy. When blindly entering the chest, the electric knife or trocar will damage the lung tissue. How to solve it?
