A drainage device for conveniently extracting pleural fluid samples

technical field

The utility model relates to the technical field of medical appliances, in particular to a drainage device for conveniently extracting pleural effusion samples.

Background technique

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 laboratory testing, which will provide an indispensable diagnostic basis for the next step to clarify the etiology of the pleural effusion.

At present, chest tubes with needles or surgical costal bed drainage tubes are used in clinical practice to connect closed drainage bottles. When the drainage is smooth, the gas and liquid in the chest cavity can be smoothly drained into the closed drainage bottles, so as to improve pleural effusion or gas compression. However, in clinical diagnosis and treatment, the drained pleural effusion is promptly sent to the laboratory for routine classification and biochemical detection of pleural effusion, so as to help the clinic to clarify the cause and treat it in time.
