Wound Drainage Mounting Device Reducing Torque
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wound drainage systems fail to adequately address patient comfort and safety, as they can cause discomfort due to poorly anchored drainage systems, increased muscle ache and fatigue from weight, and lack effective infection control and toxin indication.
Innovation Solution
A wound drainage system with a mounting device and container that allows rotation, incorporating an infection detector like a leukocyte esterase indicator visible through a transparent portion, and volume indicators, which can be securely attached to the patient's skin or clothing, reducing torque and enabling early infection detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drains are clipped or safety-pinned to the patient's gown, then the drainage system is secured, but the added weight pulls on the patient's neck, shoulders and back increasing muscle ache and fatigue
Solution Approach 1:
The drainage system is divided into separate functional components: a mounting device that attaches to the patient's body (shoulder or chest area) and a drainage container that connects to it. This segmentation allows the weight to be distributed to stronger body areas rather than concentrated on the neck, while maintaining secure attachment through the mounting device's anchoring mechanism
Solution Approach 2:
The mounting device acts as an intermediary between the patient's body and the drainage container. It provides a secure attachment point that distributes the weight load across the shoulder or chest area, preventing direct pulling on the neck and reducing muscle strain while maintaining reliable drainage system security
2Reliability
If the drainage system is firmly anchored to prevent patient movement, then patient safety is improved, but patient mobility and comfort are reduced
Solution Approach 1:
The mounting device incorporates dynamic attachment mechanisms that allow the drainage system to move with the patient's body movements. The adhesive mounting and flexible coupling allow the system to adapt to patient positioning changes while maintaining secure attachment, thus preserving both safety and mobility
Solution Approach 2:
The attachment strength and positioning of the drainage system can be adjusted based on patient needs. The adhesive mounting allows for repositioning and adjustment of the system's location on the patient's body, enabling optimization between security and comfort/mobility for different patient conditions
3Reliability
If infection detection capabilities are added to the drainage system, then infection control is improved, but device complexity increases
Solution Approach 1:
The drainage container incorporates self-monitoring capabilities through transparent or translucent walls that allow visual inspection of fluid characteristics. This self-service approach enables infection detection through direct observation of fluid color, clarity, and volume without requiring complex external monitoring equipment, thus improving infection control while minimizing added complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enhances patient comfort by reducing muscle strain and fatigue, while providing a safer environment by allowing for early detection of infections and minimizing exposure to toxins through improved fluid management and handling.
Implementation Method 1
the first side of the mounting device comprises an adhesive
Implementation Method 2
