Anti-blocking abdominal cavity perfusion chemotherapy drainage tube

Abstract

The invention relates to a medical drainage tube, and especially relates to an anti-blocking abdominal cavity perfusion chemotherapy drainage tube; the drainage tube comprises an inner tube used for washing and an outer tube sleeved outside the inner tube and used for draining; a plurality of fixing sheets are arranged between the outer wall of the inner tube and the inner wall of the outer tube; the end wall of one end, extending into human body abdominal cavity, of the outer tube is arranged in an arc surface extruding outwards, and the center of the arc surface is provided with a front drainage hole; the side wall of the outer tube extending into the human body abdominal cavity is provided with a plurality of side drainage holes arranged in a spiral shape on the outer tube in the axial direction; the opening of one end of the inner tube is close to the front drainage hole, and can correspondingly wash the front drainage hole; the side wall of the inner tube is provided with a plurality of washing holes corresponding to the side drainage holes. The anti-blocking abdominal cavity perfusion chemotherapy drainage tube is reasonable in structure, big in washing scope, good in drainage effect, smooth and anti-blocking, convenient in usage, so patients can be comfortable in treatment, thus better carrying out abdominal cavity heat perfusion chemotherapy.

Description

technical field [0001] The invention relates to a medical drainage tube, in particular to an anti-blocking drainage tube for peritoneal perfusion chemotherapy. Background technique [0002] Peritoneal hyperthermic perfusion chemotherapy is to mix and heat chemotherapy drugs and large-volume perfusion fluid, and then continuously circulate and infuse them into the patient's abdominal cavity at a constant temperature, and maintain them for a certain period of time. It can prevent and treat the residual cancer cells and micrometastases in the peritoneal cavity after tumor surgery, and prevent and treat peritoneal metastases. This technique needs to establish fluid circulation between the hyperthermic perfusion chemotherapy device and the abdominal cavity through the abdominal drainage tube, so the drainage tube is required to be kept unobstructed. And many patients after surgical placement of drainage tubes, especially after the placement of drainage tubes for a long time (mor...

AI Technical Summary

Problems solved by technology

However, many patients often experience tube blockage after surgical placement of drainage tubes, especially in patients with long-term placement of drainage tubes (more than 5 days) or patients with abdominal pseudomyxoma.

This makes it difficult to perform hyperthermic intraperitoneal chemotherapy after surgery

The main reasons for the blockage of the drainage tube are as follows: (1) the drainage hole of the drainage tube used in clinical use for peritoneal perfusion therapy is small, and it is easy to be blocked by the drainage; (2) when flushing, most of the liquid can only rush forward. There is no obvious effect on dredging the side holes; (3) The side holes are mostly distributed in a straight line on both sides. Once one side of the drainage tube is close to a large tissue (such as the omentum), multiple drainage holes are blocked; (4) The drainage tube The front end is mostly flat, and when the patient turns over and moves, its edges will touch the patient's abdominal organs, causing discomfort
