Background:

Closed suction drainage systems are crucial in post-operative care to manage fluid accumulation.
Maintaining system patency and sterility during drainage is essential for preventing complications.
Current methods for sampling drainage fluid can compromise system integrity and sterility.

Purpose of the Study:

To introduce a simple, patent-pending modification to existing closed suction drainage systems.
To enhance the maintenance of patency within the drainage system.
To facilitate sterile sampling of drainage fluid for laboratory analysis.

Main Methods:

A modification to standard closed suction drainage systems was developed (patent pending).
The modified system was designed to maintain a closed and sterile environment.
The system incorporates features for easy and safe sampling of drainage fluid.

Main Results:

The modification successfully maintains system patency.
The system operates in a closed and sterile manner, reducing contamination risk.
Drainage fluid can be readily sampled for laboratory analysis without compromising the system.

Conclusions:

The described modification offers a simple yet effective improvement to closed suction drainage.
This innovation enhances patient safety by maintaining sterility and system function.
The facilitated sampling capability supports accurate laboratory diagnostics.
