Hospital Wristbands with Perforated Backing Sheet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hospital identification wristbands are cumbersome to use, prone to water damage, and difficult to store and apply, especially when multiple bands are needed for patients and their family members, due to their design as long, thin strips that are not easily manageable or stackable.
Innovation Solution
A group of size-adjustable wristbands with a backing sheet and interconnected strips and liners, featuring perforations for easy separation and adhesive layers for secure attachment, allowing for easy application and storage, and the option to include patient indicia on a clear top sheet for visibility and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If wristbands are provided as long, thin, single strips, then they can be simple in structure, but they are difficult to store and manipulate due to awkward size
Solution Approach 1:
The wristband is divided into multiple individual bands arranged side-by-side on a single backing sheet, with perforations allowing easy separation. This segmentation allows multiple wristbands to be stored compactly in a stackable format while maintaining simplicity of each individual band structure.
2Adaptability or versatility
If multiple wristbands are needed for patients and family members, then identification coverage is improved, but storage and management become more difficult
Solution Approach 1:
Multiple individual wristbands are merged into a single unit by attaching them side-by-side to a common backing sheet. This allows multiple wristbands to be stored together in a compact, stackable format while still providing the versatility to create identification for multiple patients and family members.
3Reliability
If wristbands use traditional film sleeves or adhesive backed films, then water resistance is achieved, but ease of use by hospital personnel deteriorates
Solution Approach 1:
A clear film layer is used to encapsulate the paper strip and provide water resistance. The film is applied in a manner that maintains ease of use by hospital personnel, avoiding the difficulties associated with traditional film sleeves or adhesive backed films while preserving the waterproof protective function.
4Measurement precision
If wristbands require high resolution printing for barcodes and photographs, then identification accuracy is improved, but manufacturing complexity increases
Solution Approach 1:
The wristband uses a composite structure with a paper strip encapsulated in a clear film layer. This composite material approach allows for high resolution printing of barcodes and photographs while maintaining ease of manufacture, as the paper substrate provides good printability and the film layer protects the printed information.

AI summary
A group of size-adjustable wristbands is disclosed. The group of wristbands includes a backing sheet that is connected to a stub area disposed at an end of the backing sheet. A plurality of elongated strips is connected to the stub area in a side-by-side fashion. Each strip includes a first end attached to an additional stub area and a second end attached to the stub area. Each strip further includes a top surface. The group of wristbands further includes a plurality of top sheets, each top sheet having a first end and a second end. The first end of each top sheet is attached to one of the strips along a top surface thereof. Each top sheet is clear and includes a bottom side coated with a top adhesive layer. Finally, the group of wristbands includes a plurality of top liners with each top liner being sandwiched between one of the top adhesive layers and one of the strips.
