Dual-Compartment Drainage Bag Assembly for Flexible Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bodily fluid drainage systems lack flexibility in orientation and visibility management, making them cumbersome and inefficient for clinical use.
Innovation Solution
A dual-compartment drainage bag assembly with a transformable hanger that allows for suspension in various orientations and includes transparent/translucent panels with obscuring covers for fluid visibility control, along with volume indicators and air vents for efficient fluid handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional single-compartment drainage bag is used, then the device structure is simple, but the flexibility in orientation and visibility management is limited
Solution Approach 1:
The drainage bag is divided into two separate compartments (first fluid compartment and second fluid compartment), each capable of independent drainage. This segmentation allows each compartment to be oriented and managed separately, providing flexibility in orientation and visibility management while maintaining a relatively simple overall structure.
Solution Approach 2:
The drainage bag assembly incorporates multiple functions including dual-compartment fluid collection, adjustable orientation capabilities, and selective visibility control through transparent/translucent panels. This multi-functionality enables the device to adapt to various clinical scenarios without requiring multiple separate devices.
2Loss of information
If transparent panels are used for fluid observation, then visibility of fluid is improved, but patient privacy and discretion are compromised
Solution Approach 1:
The drainage bag incorporates both transparent and translucent panels at different locations. Transparent panels allow full visibility of fluid characteristics when needed, while translucent panels provide obscured viewing for privacy protection. This local differentiation of material properties enables selective visibility management based on clinical needs and patient comfort.
3Stability of the object's composition
If a rigid hanger structure is used, then the support stability is improved, but the ability to transform orientations is reduced
Solution Approach 1:
The hanger assembly incorporates movable and adjustable components that allow the drainage bag to be positioned in multiple orientations (vertical, horizontal, angled) while maintaining stable support in each position. The dynamic adjustment capability enables clinicians to optimize the orientation based on patient needs and clinical environment.
4Productivity
If multiple drainage compartments are integrated, then drainage management efficiency is improved, but device complexity increases
Solution Approach 1:
Two separate drainage compartments are integrated into a single unified bag structure with shared support and hanger mechanisms. This merging approach allows simultaneous management of multiple fluid collections (e.g., urine and wound drainage) in one device, improving drainage management efficiency without proportionally increasing overall device complexity.

AI summary
Devices used to collect bodily fluids are disclosed. The devices may include a fluid bag and a transformable hanger for mounting the fluid bag to a support structure such as a hospital bed rail. The fluid bag can include a first fluid compartment and a second fluid compartment. The devices may further include a displaceable front cover and a back cover to obscure the bodily fluids from observation.
