Description

A bronchial occluder capable of monitoring intrapulmonary pressure

technical field

The invention relates to the technical field of medical devices, in particular to a bronchial occluder capable of monitoring intrapulmonary pressure.

Background technique

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.

According to the main mechanism of lung atrophy, that is, the principle of absorptive atelectasis, when high-concentration oxygen therapy is used, the nitrogen in the alveolar gas is gradually replaced by oxygen, and the oxygen in the alveoli diffuses into the pulmonary circulation, resulting in alveolar atrophy. Therefore, after the bronchus is blocked by pure oxygen ventilation, a closed pure oxygen space is formed in the blocked side lung. With the rapid absorption of oxygen in the alveoli, the alveoli shrink rapidly. If this process is carried out before the pleura is opened, it is a A "lung atrophy before thoracotomy" mode, which is different from the conventional mode, can complete lung atrophy during the period of disinfection and draping before thoracotomy, and can perform surgery after thoracotomy without waiting for the surgeon, which solves the above The long-term problem of lung atrophy with bronchial occluder. 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?

In the principle of absorption atelectasis mentioned above, alveolar atrophy leads to a decrease in alveolar pressure. The process of lung atrophy is accompanied by a decrease in intrapulmonary pressure. The faster the alveolar gas is absorbed into the blood, the faster the lung shrinks. The pressure in the alveoli decreases faster. Therefore, the degree of lung shrinkage before thoracotomy can be accurately assessed by monitoring intrapulmonary pressure. Therefore, a pressure monitoring system was integrated into the bronchial occluder, and this bronchial occluder with intrapulmonary pressure monitoring was designed. With this product, after bronchial occlusion, when the designated intrapulmonary pressure is detected, it means that the lung shrinkage has been completed, and the pleura can be safely opened for surgery.

The blocking air bag 3 is a spherical structure after inflation.

One end of the pressure measuring connecting tube 11 is a convex Luer lock device, and one end of the suction tube 2 is a concave Luer lock device.

The end of the suction tube of the bronchial occluder of the present invention is connected with a set of pressure sensors, and the head end of the suction tube is at the front section of the blocking airbag. When the airbag is inflated to block one side of the lung, the suction tube opening at the front section of the airbag is located at the blocking side. The bronchi of the lungs are used to sense the pressure in the lungs, and a pressure sensor connected to the end of the suction tube can monitor the pressure in the lungs. In addition to the role of conventional bronchial occluders in performing bronchial occlusion, the key is to dynamically assess the degree of atrophy of the lungs in the chest cavity before thoracotomy by monitoring intrapulmonary pressure. Lung atrophy, that is, the lung atrophy can be completed during the period of disinfection and draping before opening the chest, and it can be completed within 10 minutes, which solves the problem of long time for bronchial occluder lung atrophy; the second is to accurately evaluate lung atrophy by monitoring the intrapulmonary pressure When the intrapulmonary pressure reaches -5 ~ -15mmHg, the lung atrophy score can reach more than 9 points, that is, the state of complete atrophy. Entering the chest at this time can prevent the electric knife or trocar from damaging the lung tissue.
