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 enriching exfoliated tumor cells, comprising a main body of the drainage tube, one end of the main body of the drainage tube located in the thoracic and abdominal cavity is provided with a platform-shaped bending part, and the platform-shaped bending part is connected with the peritoneal effusion Grooves for depositing exfoliated tumor cells are provided at the steps opposite to the flow direction. In the present invention, the position of the drainage tube in the body is set as a bent structure, and a groove is set at the step corresponding to the flow direction of the peritoneal fluid, which increases the chance of tumor cells staying and enriching, and can ensure that the tumor cells will be settled and adsorbed when they pass through In the tube, it improves the detection rate of tumor cells, effectively avoids the missed diagnosis of tumorous pleural effusion, and provides a reliable guarantee for early treatment of patients.

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...
