Description

Technical Field

[0001] The utility model relates to an extracorporeal drainage device for hepatobiliary surgery, belonging to the technical field of medical consumables. Background Art

[0002] Drainage devices are usually used to guide fluid accumulated in the surgical site after surgery and eventually discharge it from the body. During hepatobiliary surgery, medical staff can judge the patient's recovery status to a certain extent based on the color, composition and volume of the discharged fluid.

[0003] Traditional drainage devices are complicated to use, and it is difficult to continue drainage when there is too much fluid accumulation, because it is generally necessary to pause and drain the liquid in the drainage container before continuing the drainage operation. Even if a disposable drainage bag is used, the drainage bag and the drainage tube are integrated, so it is necessary to pause the drainage and replace the drainage device. Summary of the invention

[0004] The utility model aims to provide an extracorporeal drainage device for hepatobiliary surgery. Through the design of a disposable liquid storage bag, the drainage bag and the drainage tube are detachable structures, thereby avoiding the need to drain the liquid after the liquid storage bag is full during extracorporeal drainage, thereby reducing the difficulty of use. At the same time, the internal structure design of the liquid storage bag avoids liquid leakage, thereby facilitating use by medical staff. And through the design with a Moffitt dropper, the drainage speed is visualized, thereby avoiding secondary damage to the patient due to excessive flow rate.

[0005] The utility model adopts the following technical solutions:
