Distributed anti-clogging abdominal cavity hyperthermal perfusion drainage tube

Abstract

The invention discloses a distributed anti-clogging abdominal cavity hyperthermal perfusion drainage tube. The upper ends of four dual-cavity catheters are always integrally connected with the lower end of a total tube in a cross shape, the total tube is internally provided with four main flushing cavities and four main drainage cavities, the lower ends of the four main flushing cavities are communicated with flushing cavities of four dual-cavity catheters respectively, and the lower ends of the four main drainage cavities are communicated with the drainage cavities of the four dual-cavity catheters respectively; four drainage connectors communicated with the main drainage cavities and four washing connectors communicated with the main flushing cavities are arranged at the upper end of the total tube. Compared with the prior art, the number of pipes which penetrate through the abdominal wall is the smallest, and the risk can be effectively avoided that discomfort is induced since the catheters are left in the body and stimulate the peritoneum and organs.

Description

technical field [0001] The invention relates to a medical device, in particular to a decentralized anti-clogging abdominal cavity heat perfusion drainage tube. Background technique [0002] For patients who are going to undergo hyperthermic perfusion of the abdominal cavity, it is generally necessary to place infusion tubes symmetrically up and down, left and right, to the subdiaphragm and pelvic floor after abdominal and pelvic surgery, so that the perfusion fluid can fill the peritoneal cavity. Generally, 4 catheters are placed. Multiple drainage tubes can effectively lavage the entire abdominal cavity and drain thoroughly. However, placing multiple drainage tubes not only increases the pain, trauma and infection risk of patients, but also does not conform to the current minimally invasive concept. The second common risk is the blockage of the peritoneal hyperthermic perfusion tube: patients with hyperthermic perfusion are usually placed after surgery, but postoperative p...

However, placing multiple drainage tubes not only increases the pain, trauma and infection risk of patients, but also does not conform to the current minimally invasive concept

The second common risk is the blockage of the peritoneal hyperthermic perfusion tube: patients with hyperthermic perfusion are usually placed after surgery, but postoperative pelvic abdominal necrotic tissue blockage and adhesion formation may lead to drainage tube blockage, or form a wrap around the drainage tube Cyst, leading to poor thermal perfusion, usually 3 days after surgery may block the tube

[0004] At present, the drainage tube is fixed by sutures. Loose knots and infection around the drainage tube mouth may cause the drainage tube to fall off, resulting in treatment failure.
