Description

Critical care drainage device

Technical field

The utility model relates to the technical field of medical devices, specifically a critical care drainage device.

Background technique

Severely ill patients will have effusion inside the pleural cavity after surgery, and the effusion will seriously endanger the patient's recovery. Therefore, the effusion inside the pleural cavity needs to be drained out in time. Currently, the draining out of the pleural effusion relies on the nurse inserting a needle into the patient. The pleural cavity is then used to drain the effusion with a syringe. Since the syringe is used to extract the effusion, the pulling force for extracting the effusion is difficult to control. In this way, since the drainage device repeatedly contacts the outside air and the inside of the thoracic cavity, it is easy for air containing bacteria from the outside to enter the thoracic cavity. , causing cross-infection and increasing the chance of postoperative complications.

The patent document with the prior art publication number CN 216725358 U provides a critical care drainage device, which automatically cleans the box through a water spray nozzle and a cleaning brush, thereby avoiding the need for manual cleaning of the drainage device, which would increase the number of medical personnel.
