Problems solved by technology

Under normal circumstances, the amount of pleural and ascites is about several thousand milliliters, and clinically, 5-10ml of pleural and ascites is randomly extracted with a drainage tube for inspection; however, due to the small number of cancer cells in the early stages of cancer, missed diagnosis may occur , so as to delay the patient's condition

Abstract

The invention discloses a drainage tube for gathered tumor cast-off cells. The drainage tube comprises a drainage tube body. The end, located in the thoracic and abdominal cavity, of the drainage tube body is provided with a platform type bent portion. A step, opposite to the flowing direction of seroperitoneum, of the platform type bent portion is provided with a groove used for depositing the tumor cast-off cells. The portion, located in a human body, of the drainage tube is set to be of a bent structure, the groove is formed in the step corresponding to the flowing direction of seroperitoneum, the chance of staying and gathering of the tumor cast-off cells is increased, and it can be guaranteed that the tumor cast-off cells will be deposited and sucked into the drainage tube when passing through the drainage tube; the tumor cell detection rate is improved, missed diagnosis of tumorous pleural fluid and ascites is effectively avoided, and a reliable guarantee is provided for pretreatment of a patient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a drainage tube for draining pleural and ascites. Background technique [0002] Pleural and peritoneal effusions are frequently-occurring and common diseases of clinical respiratory system and digestive system. There are many common causes, such as cardiovascular disease, liver disease, peritoneal disease, kidney disease, nutritional disorder, malignant tumor peritoneal metastasis, ovarian tumor , connective tissue diseases, etc., if the disease forms too much pleural effusion, it will become pleural effusion. The examination of pleural and ascites is clinically used to determine the cause and etiology of the formation of pleural and ascites by examining the properties of pleural and ascites, and it plays a guiding role in the treatment of clinical diseases. [0003] Malignant pleural effusion refers to the abnormal increase of body cavity fluid caused by malignant tumor...
