AI Technical Summary

Technical Problem

The existing pleural effusion drainage tube is easily blocked by the cells and fibrous tissue that fall out of the patient's body, resulting in the inability to drain the effusion at one time. It needs to be frequently pulled out and reinserted into the drainage tube, which is cumbersome to operate and increases the patient's pain.

Method used

A dredging structure including a effusion pot, a first connecting pipe, a second connecting pipe and a third connecting pipe are designed, and a blocked first pipeline is connected to the syringe by rotating the valve, and a new passage is formed. Implement a drainage device that can be unblocked without removing the drainage tube.

Benefits of technology

It realizes that effusion can be drained in one go without removing the drainage tube, reducing drainage time and reducing patient pain and operation complexity.

Abstract

The utility model provides a dredging structure for a pleural effusion drainage tube and a drainage device. The dredging structure comprises an effusion pot; the liquid accumulation pot is provided with a first connecting pipe, a second connecting pipe and a third connecting pipe; a first air outlet pipe is integrally formed on the second connecting pipe, a first valve is installed in the first air outlet pipe, a second air outlet pipe is integrally formed on the third connecting pipe, a second valve is installed in the second air outlet pipe, and the third connecting pipe is provided with a connecting port. When the drainage device is used, the drainage tube of the existing drainage device for pleural effusion is cut off, and the drainage tube at the cut-off position is respectively connected with the first connecting tube and the second connecting tube of the effusion pot; when the first pipeline is blocked, the first valve is rotated to seal the second connecting pipe, the second valve is rotated to open the third connecting pipe, an injector is connected to the connecting opening, and the first pipeline is dredged by using the injector to extract air or inflate air. The dredging structure is used for the pleural effusion drainage device, and the drainage tube can be dredged without being pulled out.
