This external drainage process is usually achieved by cutting small holes in the skin and implanting a drainage tube or catheter. One end of the drainage tube is connected to the part of the patient's body where the fluid accumulates, and the other end is fixed outside the skin through a pipeline, so that the fluid in the body can flow out smoothly through the drainage tube.

[0003] Chinese Patent CN220558397U discloses a flow rate monitoring device for real-time monitoring of the fluid flow rate in a thoracic drainage tube, which includes a clamping body and a monitoring system.

On the upper side of one end of the lower clamping plate, there is a lower clamping arc groove for clamping the lower side wall of the thoracic drainage tube. The thoracic drainage tube is firmly clamped between the upper clamping arc groove and the lower clamping arc groove.

[0023] When the utility model is adjusted, the drainage tube is clamped between the upper arc groove and the lower arc groove matching the diameter of the drainage tube according to the diameter of the drainage tube. By pushing the limit block left and right to move, the flow velocity sensor is driven to move directly above the drainage tube, so that the flow velocity sensor can monitor the flow velocity of the liquid in the drainage tube in real time and convert it into an electrical signal to be transmitted to the controller; at the same time, the connecting block drives the spring buffer to move left and right, so that the roller moves into the groove of the wavy groove. At this time, resistance will be received when pushing the limit block, so that it can accurately judge whether the flow velocity sensor moves in place according to the resistance, and can play a limiting role on the flow velocity sensor after moving in place, and can monitor drainage tubes with different diameters, with high applicability.
