Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and more specifically, particularly relates to a drainage tube arrangement and fixing device. Background Art

[0002] During hepatobiliary surgery, the bile or gallbladder needs to be drained with the help of a drainage tube. When draining the bile or gallbladder, in order to ensure that the drainage tube is in the correct position and to avoid displacement or twisting of the drainage tube that affects the drainage effect, it is usually necessary to use a fixing device to position the drainage tube.

[0003] For example, the existing application number CN202122294048.6 discloses a drainage tube fixture, which includes: a main body and a fixing part, wherein the main body can be selectively arranged on the skin of a human body; the fixing part is multiple, which is arranged on the main body and arranged in the longitudinal direction of the main body, and the fixing part is used to fix the drainage tube. Therefore, by arranging multiple fixing parts on the main body, it is possible to meet the needs of fixing multiple drainage tubes at the same time, improve the convenience of fixing the drainage tubes, reduce the probability of multiple drainage tubes being entangled with each other, avoid damage to the drainage tubes, and facilitate the patient's recovery. In addition, the structure is simpler and easier to operate, which improves the safety of use and work efficiency, and can reduce medical costs.

[0004] Based on the above, when fixing the drainage tube, most of them use a fixer to stick one end of the drainage tube on the patient's skin, and the other end of the drainage tube is fixedly connected to the drainage bag.
