结核性胸腔积液是结核病的常见病，多发病。临床上常用胸腔穿刺术穿刺抽出胸水,由于反复穿刺增加了患者的痛苦及胸腔内感染、气胸等并发症的机会，胸膜反应亦较常见。目前，临床上应用的胸腔引流管多为单腔胸管，只起到引流的作用。单腔胸腔引流管不利于胸腔内注射药物或胸腔冲洗；在注药时需反复分离连接口，易导致逆行性污染；当持续引流胸腔积液时，引流袋高于穿刺点时易引起逆流感染。Tuberculous pleural effusion is a common and frequently-occurring disease of tuberculosis. Thoracentesis is commonly used clinically to extract pleural effusion. Repeated punctures increase the patient's pain and the chance of complications such as intrathoracic infection and pneumothorax. Pleural reactions are also more common. At present, most of the chest drainage tubes used clinically are single-lumen chest tubes, which only serve as drainage. Single-cavity chest drainage tubes are not conducive to intrapleural injection of drugs or chest flushing; the connection port needs to be repeatedly separated when injecting drugs, which can easily lead to retrograde contamination; when continuous drainage of pleural effusion, when the drainage bag is higher than the puncture point, it can easily cause reflux infection .
