Stimulation Garment for Pressure Ulcer Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for preventing pressure ulcers in individuals with compromised mobility and lack of sensation are ineffective due to the need for direct electrode-skin contact, which causes skin irritation and mechanical pressure points, and require frequent repositioning or expensive specialized equipment.
Innovation Solution
A composite garment with a form-fitting, stretchy main body and non-stretchy openings for electrode placement, secured by a loose-fitting back panel, allowing for intermittent electrical stimulation without direct skin contact, minimizing mechanical stress and enabling long-term use without caregiver assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrodes are directly applied to the skin for electrical stimulation, then effective muscle stimulation is achieved, but skin irritation and mechanical pressure points occur
Solution Approach 1:
A non-conductive mesh garment serves as an intermediary between the electrodes and the skin. The mesh structure allows electrodes to be positioned and secured without direct skin contact, eliminating skin irritation while maintaining electrical stimulation effectiveness through the mesh material.
2Ease of operation
If fixed-placement electrodes are used in garments, then electrode positioning is simplified, but adaptability to different patients is reduced
Solution Approach 1:
The garment incorporates stretchable material and flexible mesh structures that allow the garment and electrodes to adapt dynamically to different body shapes and sizes. This enables easy electrode positioning while maintaining adaptability to various patients without requiring fixed, non-adjustable placements.
3Object-affected harmful factors
If specialized mattresses and cushions are used for pressure relief, then tissue pressure is reduced, but cost and weight increase
Solution Approach 1:
The invention replaces passive mechanical pressure-relief systems (specialized mattresses and cushions) with active electrical muscle stimulation through a lightweight garment. The electrical stimulation actively engages muscles to dynamically redistribute body weight and reduce pressure on vulnerable tissues, achieving pressure relief without the weight and cost of specialized equipment.
4Duration of action of stationary object
If electrodes are secured with adhesives for long-term use, then electrode stability is improved, but skin damage occurs from repeated application and removal
Solution Approach 1:
The non-conductive mesh garment acts as a mediator that secures electrodes without requiring adhesive contact with the skin. Electrodes are attached to the mesh material itself, allowing for repeated use and removal without skin damage while maintaining electrode stability and positioning throughout treatment sessions.
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 garment provides consistent and reliable electrical stimulation, redistributes pressure, increases oxygenation, and prevents skin irritation, allowing for long-term use without mechanical stress points or skin damage, effectively addressing the limitations of existing methods.
Implementation Method 1
Electrical stimulation of muscle tissue, commonly known as electrical muscle stimulation (EMS), has been examined as a means for preventing or mitigating pressure ulcer formation. EMS applied to loaded muscles produces active contraction thereof
Implementation Method 2
Reshaping of the mechanically compressed and ischemic muscle reduces tissue injury by redistributing pressure
