A drainage device and working method for conveniently extracting pleural fluid samples

Abstract

The invention discloses a drainage device facilitating extraction of a pleural fluid sample and a working method of the drainage device. According to the drainage device and the working method, an effusion cavity part is formed in a drainage bottle, a drainage tube is connected with the effusion cavity part of the drainage bottle, a baffle is arranged on the inside wall of the effusion cavity part, and a pleural fluid extract opening is further formed in the inside wall of the effusion cavity part and sealed by a rubber plug. As the pleural fluid extract opening is formed in the inside wall of the effusion cavity part of the drainage bottle, and the baffle is added into the effusion cavity part, pleural fluid flows into the hydrops area, and then flows into the bottom of the effusion cavity part after overflow; when the pleural fluid sample needs to be extracted, an injection syringe is inserted from the rubber plug to extract part of the hydrops, and the part of pleural fluid cannot be diluted by normal saline probably existing at the bottom of the pleural fluid drainage bottle and therefore conforms to the submission requirement; after completion of sample extraction, the rubber plug is still kept sealed and does not influence the negative-pressure state in the pleural fluid drainage bottle; the extracted pleural fluid is directly submitted to a laboratory for related tests, so that clinical diagnosis tracking and next-step treatment are facilitated.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a drainage device and a working method thereof for conveniently extracting pleural effusion samples. Background technique [0002] Pleural effusion is a common clinical lung disease. Pleural effusion can be caused by various lung diseases such as inflammation, malignant tumors, tuberculosis, fungi, etc., and extrapulmonary diseases such as heart failure, liver cirrhosis, pericardial effusion, Abdominal malignant tumors, pancreatitis, nephrotic syndrome, malnutrition, and chest trauma are all common causes of pleural effusion. Once a patient develops pleural effusion, when the pleural effusion is large, it will oppress the lungs and heart, and the patient will feel shortness of breath, chest tightness, hypoxemia and even respiratory failure. Therefore, in clinical treatment, the pleural effusion must be fully drained first; The pleural effusion should be submitted for ...
