Drainage tube and flushing guide pipe

Abstract

The invention discloses a drainage tube and a flushing guide pipe. The drainage tube comprises a drainage section for guiding accumulated fluid to outflow, a middle section for controlling a stretch-in position and positioning the stretch-in position and an exporting section for exporting and collecting fluid, wherein the drainage section, the middle section and exporting section are sequentially and seamlessly connected with one another; the tube body inner surface of the drainage section is provided with a first radial supporting structure for supporting the drainage section tube body and maintaining the drainage section in the radial direction, and a drainage opening which is used for guiding the accumulated fluid into a drainage cavity is formed in the outer surface of the drainage section; the tube body inner surface of the middle section is provided with a second radial supporting structure for supporting the tube body of the middle section and maintaining the middle cavity of the middle section smooth. The drainage section stretches into the fluid accumulated part, the drainage opening is formed in the drainage section, the accumulated fluid successfully enters the inner cavity of the drainage section by virtue of the drainage opening, and the accumulated fluid is led out.

Description

technical field [0001] The invention relates to the field of medical drainage devices, in particular to a medical drainage tube. In addition, the present invention also relates to an irrigation drainage tube comprising the above drainage tube. 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, abdominal cavity, and biliary tract. The purpose of surgical drainage is to guide fluids such as pus, blood, and liquid accumulated between human tissues or body cavities to the outside of the body, so as to prevent postoperative infection and affect wound healing. Therefore, the diverter is required to keep the pipeline unblocked at all times. [0003] However, the existing drainage tube is very likely to be blocked due to extrusion or bending during movement or use, causing fluid flow to be blocked, drainage failure, and secondary damage to the pa...
