Optically Transparent Viewing Window for Sterile Electronic Imaging Device Covering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sterile band bags used in medical facilities to cover electronic imaging devices, such as monitors and touch screens, lack optical clarity and tend to be thick and bulky, causing impaired vision and increased risk of mistakes due to inadvertent movement.
Innovation Solution
A covering comprising a flexible band bag sleeve with an optically transparent display screen viewing window, adhered to the device to create a sterile barrier while maintaining clear visibility and preventing displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sterile band bags are used to cover electronic imaging devices, then a sterile environment is achieved, but optical clarity is lost causing impaired vision
Solution Approach 1:
The covering is divided into two distinct parts: a sterile band bag sleeve for creating the sterile barrier, and a separate optically transparent viewing window for clear visualization. This segmentation allows each component to optimize its specific function without compromising the other.
Solution Approach 2:
Different regions of the covering have different optical properties. The viewing window area is made optically transparent with high clarity, while the rest of the band bag sleeve maintains standard sterile material properties. This local differentiation resolves the contradiction between sterility and visual clarity.
2Reliability
If traditional thick sterile band bags are used, then sterility is maintained, but the covering becomes bulky and prone to inadvertent movement
Solution Approach 1:
The viewing window is constructed as a thin, flexible optically transparent film that can conform to the display screen surface. This thin-film approach eliminates the bulkiness of traditional band bags while maintaining sterile barrier functionality, and the flexibility allows it to adhere smoothly without creating protrusions that could cause displacement.
Solution Approach 2:
The viewing window is designed to wrap around and conform to the curved surface of the display screen, transitioning from a flat two-dimensional material to a three-dimensional form that adheres to the screen's geometry. This dimensional adaptation improves stability by creating intimate contact across the entire surface.
3Reliability
If traditional sterile band bags are used, then equipment coverage is achieved, but visual perception is obscured leading to mistakes
Solution Approach 1:
The optically transparent viewing window acts as an intermediary element between the sterile band bag sleeve and the display screen. It transmits visual information from the screen to the operator with high clarity while the sterile sleeve maintains the sterile barrier, thus preserving both protection and information transmission.
Solution Approach 2:
The viewing window material is specifically selected to have high optical transparency and clarity, allowing full transmission of the display screen's visual output. This optical property enhancement ensures that no visual information is lost or distorted, resolving the contradiction between protection and information clarity.
4Reliability
If traditional bulky sterile bags are used, then sterility is ensured, but operation efficiency decreases due to displacement and confusion
Solution Approach 1:
The viewing window is pre-formed with the correct size and shape to match the display screen, and the sterile band bag sleeve is pre-assembled around it. This preliminary preparation allows for quick application to the equipment without requiring adjustment or repositioning during use, thereby maintaining operational efficiency while ensuring sterility.
Solution Approach 2:
Instead of making the entire band bag thin and flexible, the invention inverts the approach by keeping the main body of the band bag traditional and thick for sterility, while only the viewing window portion is made thin and optically clear. This selective inversion maintains sterility where needed while eliminating bulkiness only where it interferes with operation.

AI summary
A covering for an electronic imaging device with an optically transparent display screen viewing window centrally disposed in a band bag sleeve to define an inner volume with a mouth. An adherent, such as an optically transparent adhesive, is disposed on an inner surface of the viewing window for adhering to a display screen of the electronic imaging device. A cinching mechanism is operative to constrict the mouth of the band bag sleeve. A sterile barrier is thus created between the electronic imaging device and an exterior environment while permitting optically clear, stable viewing and operation of the display screen. A method for enveloping an electronic imaging device with a covering is founded on providing such a covering, causing the electronic imaging device to be received through the mouth and into the inner volume, and adhering the display screen viewing window to the display screen.
