Tracheostomy Seepage Pad with Transverse Groove and Suction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tracheostomy patients experience skin irritation and increased nursing workload due to seepage from tracheal incisions, as existing methods fail to efficiently collect and manage secretions, leading to skin redness, swelling, and contamination.
Innovation Solution
A pad with a transverse groove that couples to a suction catheter, allowing for constant suction to remove seepage before it accumulates on the skin, featuring adhesive elements for secure placement and a waterproof foam surface to prevent leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional dressings are used to manage tracheostomy seepage, then the structure is simple, but the seepage accumulates on the skin causing redness, swelling, and erosion
Solution Approach 1:
The pad is segmented into functional zones: a hydrophobic outer surface that repels seepage, a hydrophilic inner surface that absorbs seepage, and a groove structure that channels seepage toward collection points. This segmentation allows each zone to perform its specific function in managing seepage effectively.
Solution Approach 2:
The pad acts as an intermediary device between the tracheostomy site and the patient's skin/bedding. It intercepts seepage before it contacts the skin, using its layered structure and groove system to collect and remove fluid, thereby protecting the skin from irritation.
2Object-affected harmful factors
If frequent monitoring and manual cleaning of tracheostomy sites is performed, then skin irritation is reduced, but nursing workload increases
Solution Approach 1:
The pad is designed to automatically manage seepage without requiring frequent nursing intervention. The hydrophobic/hydrophilic surface combination and groove structure enable the pad to self-absorb and self-drain seepage, maintaining skin protection continuously while reducing nursing workload.
Solution Approach 2:
The pad provides continuous seepage management through its passive absorption and active suction capabilities. The groove system maintains continuous fluid removal, ensuring uninterrupted skin protection without requiring repeated manual cleaning sessions.
3Reliability
If the pad uses a fully waterproof surface, then seepage containment is improved, but seepage removal capability is reduced
Solution Approach 1:
The pad employs different surface properties in different locations: the outer surface is hydrophobic for containment and repulsion, while the inner surface接触ing the skin is hydrophilic for absorption. The groove areas have enhanced wickability to channel and remove seepage, creating local quality variations that simultaneously achieve containment and removal.
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 device enhances patient comfort by reducing skin irritation and decreases nursing workload by efficiently collecting and removing seepage, minimizing skin erosion and bed sheet contamination.
Implementation Method 1
a suction catheter tube which can apply a constant suction to the area of the groove, removing the seepage
Implementation Method 2
a waterproof foam element covers the inner surface except for the portion of the inner surface with the groove
Data Source
AI summary
The present disclosure provides a device for collecting seepage from below a tracheostomy incision on a patient by providing a pad with a groove running transversely to the flow of the seepage. The groove couples to a suction catheter tube which can apply a constant suction to the area of the groove, removing the seepage before it collects on the skin for too long or contaminates a patient's bed. This both increases patient comfort and reduces workload for nursing staff.
