Disposable Fluidproof Covers for PEMFT Medical Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical devices for pulsed electromagnetic field therapy (PEMFT) face challenges in maintaining cleanliness and hygiene due to the spread of infection and bodily fluids, with existing solutions being either ineffective or impractical for frequent use, particularly for strap-based and disc-based devices.
Innovation Solution
Disposable covers made from fluidproof material, such as spun-bound polyethylene and poly-backed wood-pulp fiber, designed to fit customly over PEMFT medical devices, providing a sealed protection and easy disposal, with detachable fasteners and elastic components for secure fit and handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If disposable covers are used, then hygiene and infection prevention are improved, but device complexity and preparation time increase
Solution Approach 1:
The cover is divided into distinct functional segments: a main body portion that covers the device, tabs for securing, and detachable fasteners for attachment. This segmentation allows each part to perform its specific function efficiently while maintaining overall simplicity in the covering system.
Solution Approach 2:
The covers are pre-formed with the correct shape, size, and attached fasteners before use. Users simply need to attach the pre-prepared cover to the device, eliminating the need for on-site preparation or complex assembly procedures.
2Loss of substance
If reusable covers are used, then cost is reduced, but cleaning time and infection risk increase
Solution Approach 1:
The patent employs disposable covers made from cost-effective materials that can be discarded after single use. This eliminates the need for repeated cleaning cycles, reduces water and chemical consumption, and ensures that each patient receives a completely fresh, uncontaminated cover, thereby maximizing infection prevention.
3Object-affected harmful factors
If tight-fitting covers are used, then fluidproof protection is improved, but comfort and ease of application worsen
Solution Approach 1:
The cover extends beyond the minimum required coverage area, with tabs that reach toward the ends of the device and fasteners positioned to secure the cover firmly. This excessive coverage ensures complete fluidproof protection while the tab-and-fastener system maintains ease of application through simple attachment points.
Solution Approach 2:
The tabs serve as intermediary elements between the main cover body and the device ends. They provide a mechanical means to secure the cover firmly in place, ensuring fluidproof protection through the fastener attachment while maintaining ease of application through the simple tab-and-fastener interface.
4Reliability
If custom-fitted covers are used, then protection effectiveness is improved, but manufacturing complexity increases
Solution Approach 1:
The cover design incorporates universal features: a standardized body shape that fits various device sizes, multiple attachment points for different device configurations, and fasteners that can be positioned at different locations. This universality allows a single cover design to effectively protect multiple device types while maintaining simple, consistent manufacturing processes.
