Description

Drainage device Technical Field The utility model relates to the technical field of medical appliances for hepatobiliary surgery, in particular to a drainage device. Background The hepatobiliary surgical drainage is to drain blood, bile, secretion, etc. accumulated in a body cavity in an operation area from an original place, thereby discharging the blood, bile, secretion, etc. to prevent accumulation in the body cavity, and secondary compression symptoms, infection, or tissue damage, and thus a drainage tube is required. The drainage tube is mostly made of medical latex materials, and the texture of the drainage tube is soft. When the drainage tube is in practical application, the drainage tube has the following problems that (1) the drainage tube is excessively bent to cause the tube wall of the drainage tube to be attached, and the flow passage inside the drainage tube is blocked or narrowed, so that the drainage is influenced and the normal medical process is influenced. (2) When the fluid accumulation in the patient is too viscous, the viscous fluid accumulation in the patient causes a certain blockage to the flow guide pipe, thereby affecting drainage and affecting the normal medical process. In the published Chinese patent application, the publication number is CN221014146U, the patent name is a drainage tube, the prior art discloses a drainage tube body, an anti-bending component is arranged in the tube body and comprises three metal strips arranged in the tube body, the three metal strips are attached to the inner wall of the tube body, connecting lines of the sections of the three metal strips form an equilateral triangle, a plurality of metal wire rings are connected between the three metal strips, the metal wire rings are distributed at equal intervals, and the metal strips and the metal wire rings are made of ductile metal wires. According to the prior art, the pipe body is just supported by the three metal strips and the metal wire ring, so that the pipe body is supported to the greatest extent, and meanwhile, the pipe body cannot be blocked due to excessive bending and folding due to the toughness of the three metal strips. Although this prior art can achieve support of the pipe body and prevent blockage of the flow passage inside the pipe body, there are certain limitations in the implementation of this prior art. The metal supporting structure is arranged in the tube body, the metal is in direct contact with the effusion, and the sanitation condition of a patient is difficult to ensure because the effusion has the possibility of countercurrent flow, and meanwhile, the prior art cannot effectively solve the problem (2). In summary, the present disclosure is specifically proposed to solve the limitation problem existing in the prior art.
