Sutureless Drain Securement Structure for Stable Skin Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing medical devices like drains and catheters to the skin, such as sutures and adhesive fixation, often lead to complications including pain, dislodgment, and infection, while failing to provide stable and comfortable attachment during patient movement and dressing changes.
Innovation Solution
A sutureless securement device comprising a housing with a vertical channel and hanger, coupled to a mounting plate with adhesive, allowing secure attachment of medical devices to the skin without sutures, enabling stable fixation and ease of dressing changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If suture is used to tie drains to skin, then securement stability is improved, but patient comfort deteriorates due to pain and risk of infection
Solution Approach 1:
The patent replaces the mechanical suture system with an adhesive-based securement system. The adhesive element is applied to the skin surface and bonds the drain to the skin without penetrating the skin, thereby eliminating the need for needles and sutures while maintaining securement stability.
Solution Approach 2:
The patent introduces an adhesive element as an intermediary between the drain and the skin. This adhesive layer provides the bonding function previously achieved by sutures, but does so without causing tissue penetration or requiring knot tying, thus reducing pain and infection risk.
2Reliability
If tight knots are used to secure drains, then securement stability is improved, but patient comfort deteriorates due to pain and infection risk
Solution Approach 1:
The patent replaces the knot-tying mechanical system with an adhesive bonding system. The adhesive element provides continuous bonding pressure without requiring tight knots, eliminating the localized pressure points and tissue deformation that cause pain and create infection pathways.
3Object-affected harmful factors
If adhesive drain fixation devices are used, then patient comfort is improved, but securement stability deteriorates over time
Solution Approach 1:
The patent divides the securement system into distinct functional components: a mounting plate for skin attachment, a vertical channel for drain positioning, and a hanger mechanism for additional security. This segmentation allows each component to perform its specific function optimally, with the adhesive providing comfort and the mechanical structures providing long-term stability.
Solution Approach 2:
The patent combines adhesive material with rigid structural elements (mounting plate, vertical channel, hanger) to create a composite securement system. The adhesive provides initial bonding and patient comfort, while the rigid structures maintain geometric stability and prevent drain displacement over time.
4Reliability
If traditional securement methods are used, then securement stability is improved, but ease of operation deteriorates during dressing changes
Solution Approach 1:
The patent segments the securement device into a removable drain portion and a fixed mounting plate portion. During dressing changes, the drain can be detached from the vertical channel and removed, while the mounting plate remains adhered to the skin, simplifying the dressing change process while maintaining securement stability.
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 provides stable, comfortable, and infection-free securement of medical devices, reducing the risk of dislodgment and pain, while allowing patient movement and facilitating easy dressing changes.
Implementation Method 1
an adhesive element on the rear face of the mounting plate, wherein the adhesive element is configured to securely couple the mounting plate to the skin of a subject
