Abdominal cavity drainage device for medical oncology

Abstract

The invention provides an abdominal cavity drainage device for medical oncology, and belongs to the technical field of abdominal cavity drainage instruments. The abdominal cavity drainage device for medical oncology comprises a drainage collecting assembly, a negative pressure adjusting assembly and a cleaning assembly. The drainage collecting assembly comprises a liquid collecting barrel, a drainage pipe, a first flow regulator, a pressure gauge and a connecting pipe, the first flow regulator is installed outside the drainage pipe, one end of the drainage pipe is communicated with the top ofthe liquid collecting barrel, and one end of the connecting pipe is communicated with the port of the pressure gauge, the other end of the connecting pipe is communicated with the top of the liquid collecting barrel, and the negative pressure adjusting assembly comprises an elastic breathing bag, an exhaust pipe, an air outlet pipe, a first one-way valve and a second one-way valve. According to the invention, while abdominal effusion is drained, normal saline in the normal saline bag flows into the abdominal cavity through an infusion tube to clean the interior of the abdominal cavity, waste liquid obtained after cleaning flows into the liquid collecting barrel along the drainage pipe, cleaning and drainage are conducted at the same time.

Description

technical field [0001] The invention relates to the field of abdominal drainage devices, in particular to an abdominal drainage device used in oncology. Background technique [0002] Drainage tube is a medical device used for clinical surgical drainage to guide pus, blood, and liquid accumulated between human tissues or body cavities to the outside of the body to prevent postoperative infection and promote wound healing. There are many types of surgical drainage tubes used clinically, some are used for catheterization, some are used for wounds, and they are used in the chest cavity, brain cavity, gastrointestinal tract, and biliary tract. [0003] The existing peritoneal effusion drainage method adopts a simple drainage tube to drain the effusion to the inside of the liquid collection barrel. The drainage method is single, and the drainage of the peritoneal effusion cannot be cleaned at the same time. Contents of the invention [0004] In order to make up for the above de...
