Protective Cover for C-Arm Flat-Plate Detectors With Strap Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current C-arm detector covers are flimsy and prone to tearing, leading to breaches in the sterile field, causing delays and infection risks during medical procedures.
Innovation Solution
A cover with a panel and straps featuring a hook-and-loop closure mechanism is designed to securely fit over C-arm detectors, maintaining a sterile environment by snugly engaging the detector and using durable materials like nylon.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flimsy covering materials are used on C-arm detector plates, then the cover is easy to manufacture and install, but the sterile field is breached due to tearing and perforation during medical procedures
Solution Approach 1:
The cover is constructed from multiple layers of radiolucent material including a sterile drape layer, a reinforcement layer with cross-hatch pattern, and a adhesive layer. This composite structure provides both sterility maintenance and tear resistance, resolving the contradiction between sterile field integrity and material strength.
Solution Approach 2:
The cover uses flexible radiolucent material that can conform to the C-arm detector plate surface while maintaining structural integrity. The flexible nature allows the cover to remain intact during patient positioning and surgical manipulation, preventing breaches while maintaining sterility.
2Productivity
If flimsy covering materials are used on C-arm detector plates, then the manufacturing cost is reduced, but procedural delays occur due to breaches requiring cover replacement
Solution Approach 1:
The cover incorporates a reinforcement layer with cross-hatch pattern and strategic reinforcement zones at corners and edges before the procedure begins. This pre-reinforcement prevents tears and perforations during the procedure, eliminating the need for cover replacement and maintaining surgical continuity.
3Reliability
If a secure closure mechanism is added to the C-arm detector cover, then the sterile field protection is improved, but the device complexity increases
Solution Approach 1:
The cover is divided into functional layers (sterile drape layer, reinforcement layer, adhesive layer) that can be manufactured separately and assembled. This segmentation allows each layer to perform its specific function while maintaining overall simplicity. The closure mechanism uses discrete straps with hook-and-loop fasteners positioned at specific locations rather than a continuous complex system.
Solution Approach 2:
The hook-and-loop fastener system allows the cover to be self-securing without requiring additional tools or complex mechanisms. The straps can be easily fastened and adjusted by the user, providing secure closure while maintaining operational simplicity.
4Reliability
If durable radiolucent material is used for the C-arm detector cover, then the sterile field integrity is maintained, but the manufacturing cost increases
Solution Approach 1:
The cover uses a composite structure with a base layer of radiolucent material combined with a reinforcement layer. This allows the use of durable materials only where structurally necessary (reinforcement zones at corners and edges) while using simpler materials in other areas, balancing durability with manufacturing feasibility.
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 cover effectively maintains a sterile field, preventing contamination and reducing procedural delays by ensuring the integrity of the sterile environment.
Implementation Method 1
The cover includes a hook-and-loop closure mechanism which has a hooked portion and a looped portion. Each strap has a fixed end portion and a free, opposite end portion. The free end portion of one strap includes the hooked portion and the free end portion of the other strap includes the looped portion.

AI summary
A cover for a mini C-arm machine having a detector is designed to maintain a sterile field for a detector screen. The cover includes a panel having at least three integral sides, two being spaced-apart parallel to each other. The cover includes a pair of straps. One of the straps has an end portion fixed to one of the two parallel sides. The other strap has an end portion fixed to the other of the two parallel sides. The cover includes a hook-and-loop closure mechanism having a hooked portion and a looped portion. Each strap has a fixed end portion and a free, opposite end portion. The free end portion of one strap includes the hooked portion and the free end portion of the other strap includes the looped portion. Each closure portion is sized, when the closure portions are engaged, to retain the panel against the detector.
