Embodiment approach
[0044] As an embodiment of the present invention, the anti-falling unit 2 further includes:
[0045] An air ring 24, the air ring 24 is located on the inner wall of the drainage tube main body 1, and the air ring 24 is connected with the position of the air channel one 22 close to the outer wall of the drainage tube main body 1, the air ring 24 are equidistantly distributed along the airway-22;
[0046] When working, after the air bag 21 is inflated, there is still gas support in the airway 22. Since the gas ring 24 is on the airway 22, when some actions of the patient distort the main body 1 of the drainage tube in the body, The airway-22 is deformed, and the gas in the airway-22 flows to the two ends of the airway-22 centering on the twist point where the main body of the drainage tube 1 twists, so that the total amount of gas at both ends of the airway-22 increases, thereby making the The air ring 24 on the airway one 22 is filled, and then the air ring 24 forms an annular...

The invention belongs to the field of medical instruments, and particularly relates to a drainage tube used after hepato-pancreato-biliary surgery. The drainage tube comprises a drainage tube main body, wherein the top end of the drainage tube main body is provided with a drainage hole, and the drainage tube main body comprises an anti-falling unit and an anti-blocking unit; the anti-falling unit comprises an air bag, air passages I and an an air ring, and the top of the drainage tube main body is fixedly connected with the air bag; the air passages I which are uniformly distributed are formed in the inner wall of the drainage tube main body; the air ring is positioned on the inner wall of the drainage tube main body and is connected with the part, which is close to the outer wall of the drainage tube main body, of the air passage; the anti-blocking unit comprises an air resistance sleeve, a partition plate, guide wires and a rotating device, and the air resistance sleeve is fixedly connected to the interior of the drainage tube main body; the partition plate is fixedly connected to the position of a vertical center line in the drainage tube main body; the bottom of the air resistance sleeve is fixedly connected with the guide wires which are uniformly distributed; and the outer wall of the drainage tube main body is rotationally connected with the rotating device. The drainage tube is simple in structure and can be fixed in the human body, and meanwhile, the possibility that the drainage tube is blocked is reduced.
Description
technical field [0001] The invention belongs to the field of medical devices, in particular to a drainage tube for hepatobiliary and pancreatic surgery. Background technique [0002] Drainage tube is a medical device used for clinical surgical drainage to guide pus, blood, and fluid accumulated between human tissues or body cavities to the outside of the body to prevent postoperative infection and promote wound healing; there are many types of surgical drainage tubes used clinically , some are used for catheterization, some are used for wounds, chest cavity, brain cavity, gastrointestinal tract, biliary tract, etc.; surgical drainage is to guide pus, blood, and fluid accumulated between human tissues or body cavities to In vitro, to prevent postoperative infection and affect wound healing. [0003] In hepatobiliary and pancreatic surgery, the placement of the drainage tube is of vital significance. It is especially important to ensure the surgical effect and prevent the occ...
