Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to an external drainage device after laparoscopic surgery. Background Art

[0002] After laparoscopic liver surgery, pus, body fluids, blood, bile, etc. will accumulate between human tissues or in the body cavity. Therefore, it is necessary to place a drainage tube in the patient to drain these fluids out of the patient's body to prevent postoperative infection. Some patients need to leave the abdominal drainage tube in place and follow up at home for observation and recovery. It is extremely important for such patients to regularly disinfect and care for the drainage tube and record and handle the discharge in the drainage bag.

[0003] At present, most patients deal with indwelling drainage tubes at home by wrapping gauze around the connection between the drainage tube and the human body and fixing it with tape, and then directly connecting a drainage bag to the outside of the drainage tube. Patients need to observe and record the amount and color of the discharge in the drainage bag every day, and the drainage bag needs to be replaced every day.

[0004] Currently, the drainage tube left in place at home after surgery is merely wrapped in gauze and taped, and the patient may easily sweat or accidentally pull on the tape, causing the tape to loosen and causing the drainage tube to fall off the body. In addition, when the patient is asleep, the drainage tube may be easily pulled out and injured due to turning over. Moreover, the fluid discharged from the body needs to be observed and recorded every day in the drainage bag, and the drainage bag needs to be taken down and dumped, which is extremely troublesome and not conducive to the patient's independent operation at home.
