AI Technical Summary

Technical Problem

Existing pleural effusion drainage bags require cutting them open when removing sediment, which can easily cause pleural effusion to spill out and pollute the environment, and is also inconvenient to operate.

Method used

Design a drainage bag that can collect pleural effusion and sediment separately, comprising a drainage bag body, a fluid discharge component, a sediment collection component, and a pleural effusion collection component. Separate sediment and pleural effusion through a filter screen, collect them separately, and seal them to avoid cutting the bag.

Benefits of technology

It achieves efficient separation and collection of sediment and pleural fluid, reduces environmental pollution, is simple to operate, avoids pleural fluid leakage, and improves operational efficiency.

Abstract

The utility model discloses a drainage bag capable of collecting pleural effusion and sediment respectively. The lower portion of a drainage bag body is in a hopper shape. The liquid outlet assembly is arranged at the bottom end of the drainage bag body and comprises a liquid outlet channel arranged at the bottom end of the drainage bag body; a manual valve is arranged on the liquid outlet channel and is used for controlling the liquid outlet channel to be opened or closed; the sediment collecting assembly comprises a cylindrical first box body, the top end of the first box body is provided with a liquid inlet, and the liquid inlet is provided with a protective cap; a filter screen is fixedly arranged in the first box body and is used for filtering precipitates; the pleural effusion collecting assembly is arranged below the sediment collecting assembly, and when the second box body is installed at the bottom end of the first box body, the pleural effusion collecting assembly is used for collecting pleural effusion. According to the drainage bag capable of respectively collecting pleural effusion and sediment, the whole operation process is simple, convenient and environment-friendly; the operation of cutting off the drainage bag in a traditional mode is avoided, and meanwhile the problem that pleural effusion leaks to pollute the environment when the drainage bag is cut off is avoided.
