Novel medical peritoneal drainage tube and use method thereof

Abstract

The invention provides a novel medical peritoneal drainage tube and a use method thereof. The novel medical peritoneal drainage tube comprises a drainage tube, a negative pressure tube, a first side tube, a second side tube and a fixing loop, wherein multiple first through holes are formed in the side wall of the drainage tube; the negative pressure tube is fixed in the drainage tube through the fixing loop; a vent hole is formed in the fixing loop; the first side tube and the second side tube are both arranged on tube walls of the drainage tube; one end of the second side tube extends out of one end of the drainage tube. The novel medical peritoneal drainage tube can clean polluted tissue in the body cavity and drain polluted tissue fluids in the body cavity outside of the human body cavity through suction of the negative pressure tube. With the adoption of the novel medical peritoneal drainage tube, the polluted tissue fluids in the body cavity can be drained clean, the internal environment of the body cavity can be clean, inflammations are localized, tissue repair is facilitated, and postoperative infection diffusion and effects on wound healing can be prevented.

Description

Technical field [0001] The present invention relates to the field of medical devices, in particular to a new type of medical abdominal drainage tube and a method of use thereof. Background technique [0002] There are many types of surgical drainage tubes used clinically, some are used for catheterization, and some are used for wounds, chest cavity, brain cavity, gastrointestinal tract, biliary tract, etc. Surgical drainage is to guide the pus, blood, and fluid accumulated between human tissues or body cavities to the body to prevent the spread of postoperative infection and affect wound healing. [0003] At present, most of the various drainage tubes commonly used in clinical practice have a single function. They can only drain but cannot be flushed. There are only a small number of drainage tubes that can be flushed. However, their design is unreasonable. For example, the current clinical application of Kangli drainage tubes has advanced The water pipe is sheathed in the suction...

Problems solved by technology

[0003] At present, most of the various drainage tubes commonly used in clinical practice have single functions, can only drain, and cannot be washed, and there are only a few drainage tubes that can be washed, but their design is unreasonable. The water pipe is set in the suction pipe, and the water flow cannot be released into the human organs and tissues outside the pipe, resulting in a dead cycle in which the water is sucked out in the pipe after entering the water, which cannot play the role of washing the human organs and tissues

Chinese patent (application number: 201520472866.2, publication date: January 13, 2016) discloses a medical flushing and drainage tube. The flushing and drainage tube provided by the patent is provided with an outer sleeve, an inner sleeve and two side tubes. Embedded inside the outer cannula, the two side tubes are set outside the inner cannula. When in use, the space between the second side tube and the first side tube may be blocked by human tissue, and at the same time, there is no way to connect the tissues in the wound or the body cavity. The pus, blood, and fluid accumulated in the wound are diluted and completely drained to the outside of the human body, which can easily cause wound infection
