Perforated Catheter Securement Device for Infection Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Catheter-related bloodstream infections and skin complications arise from the difficulty in removing and replacing stabilization dressings without disrupting the intravenous catheter insertion site, leading to risks of phlebitis and infection.
Innovation Solution
A catheter securement device with a base featuring a perforation that separates upon lateral shear force application, allowing for easy removal without disrupting the catheter or skin insertion site, and incorporating medical-grade adhesive and antiseptic or antimicrobial agents to reduce infection risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stabilization dressing is adhered to the skin or catheter to secure the catheter, then the catheter is securely fixed, but the dressing becomes difficult to remove without moving the catheter and disrupting the insertion site
Solution Approach 1:
The base is divided into multiple segments by incorporating a perforation that allows the base to separate into a first portion and a second portion. This segmentation enables the dressing to be removed from the skin while leaving the catheter secured, resolving the contradiction between secure fixation and easy removal.
Solution Approach 2:
The perforation allows extraction of the base from the skin surface without extracting the catheter. The base can be separated into portions and removed while the catheter remains anchored, eliminating the need to disrupt the insertion site during dressing changes.
2Strength
If the base is made with strong adhesive to ensure secure attachment, then the dressing remains firmly attached, but removal requires excessive force that may disrupt the catheter or skin
Solution Approach 1:
The base is segmented by the perforation into a first portion and a second portion, allowing the adhesive base to be separated from the skin surface. This enables strong adhesive attachment during use while allowing painless removal without disrupting the catheter or skin, as the segments can be peeled apart cleanly.
Solution Approach 2:
The perforation acts as an intermediary structure that mediates between the strong adhesive base and the skin/catheter system. It provides a controlled separation path that allows the adhesive to maintain strong attachment during use while enabling clean removal without harmful forces being applied to the catheter or skin.
3Reliability
If the dressing is replaced every 72-96 hours to reduce infection risk, then patient safety is improved, but frequent removal and replacement increases the risk of skin disruption and phlebitis
Solution Approach 1:
The base is segmented by the perforation into separable portions that allow the dressing to be removed from the skin without removing the catheter. This enables safe replacement every 72-96 hours according to CDC guidelines while minimizing skin disruption and phlebitis risk through painless, clean removal.
Solution Approach 2:
The perforation enables extraction of the base from the skin surface without extracting the catheter. This allows frequent dressing changes every 72-96 hours to prevent infection while avoiding the skin disruption and phlebitis that would result from traditional removal methods.
