Background technique

The purpose of surgical drainage is to guide fluids such as pus and blood accumulated between human tissues or in body cavities to the outside of the body, so as to prevent postoperative infection and affect wound healing. When using the drainage tube clinically, the following points must be paid attention to: ① Keep the drainage tube unobstructed, and observe it at all times. ② When using the drainage tube, pay attention that the position of the outlet of the drainage tube should not be higher than the plane of the intubation port of the patient. When moving the patient, the drainage tube should be clamped first to prevent backflow; Clean the mucous membrane contact area to prevent infection.

In abdominal surgery, it is often necessary to use a drainage device to remove the fluid remaining in the abdominal cavity after the operation. Most of the drainage tubes of the existing drainage devices are round tubes made of silica gel. When used, they have the following disadvantages: ① Drainage effect Poor, unable to completely remove the residual fluid in the abdominal cavity after surgery, which may easily cause infection of the patient's wound; ②The drainage tube is prone to twisting, bending and compression during use, causing the drainage channel to be blocked, resulting in poor drainage and affecting Drainage effect; ③The range of the drainage tube and the intraperitoneal cavity is limited, and it cannot adapt to the situation where multiple places need to be drained at the same time, and the practicability is poor.

Beneficial effects of the utility model: the abdominal cavity drainage device of the utility model includes a drainage tube and a suction assembly; the drainage tube includes a flexible dipping tube and a flexible catheter, and the liquid outlet of the flexible dipping tube is connected to the flexible fluid guiding tube. The liquid inlet of the pipe is connected, and the pipe wall of the flexible dipping tube is distributed with liquid drawing holes; the suction assembly includes a sealed liquid storage bottle and a suction air bag connected with the liquid storage bottle, and the liquid storage bottle is connected to the flexible guide tube. The liquid outlet of the liquid pipe is connected, and the suction air bag and the liquid storage bottle are connected through an intake check valve. An exhaust port with an air outlet check valve is arranged on the suction air bag. When in use, the flexible dip tube Placed at the effusion in the peritoneal cavity, so that the nozzle of the flexible catheter is lower than the position of the flexible dipping tube. Under the action of the suction balloon, the liquid enters the flexible dipping tube through the nozzle and the dipping hole of the flexible dipping tube. The tube is transported to the liquid storage bottle through the flexible catheter to achieve a good drainage effect. In addition, because the drainage tube is provided with reinforcing ribs, it can effectively prevent the flexible suction tube from being squeezed and deformed and then blocked, which is beneficial to The drainage channel is unobstructed, and at the same time, setting multiple dipping tubes can also enhance its practicability.
