Multi-Tier Back-Table Drape Single-Person Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-tier back-table drapes are confusing to deploy, often requiring two technicians and increasing the risk of contamination and overhead costs, as they complicate the process of maintaining sterility during medical procedures.
Innovation Solution
A single, contiguous fabric drape with instructional content and design features such as hand slots and lift fasteners allows for easy deployment by a single technician, minimizing contamination risk and reducing personnel requirements, while accommodating various table sizes and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a multi-tier back-table drape is used to cover multiple surfaces, then the sterility of the operating environment is maintained, but the complexity of deployment increases and requires at least two technicians
Solution Approach 1:
The drape is divided into multiple distinct fabric portions (first fabric portion for lower table surface, second fabric portion for upper table surface, third fabric portion as vertical panel) that are connected but can be deployed independently. This segmentation allows a single technician to manage each portion separately, reducing deployment complexity while maintaining sterility across all surfaces.
Solution Approach 2:
The vertical panel (third fabric portion) acts as an intermediary element that connects the lower and upper table surface covers. It serves as a mediator that allows the drape to transition from requiring two technicians to being deployable by one, as the vertical panel can be used to lift and position the upper portion after the lower portion is secured.
2Reliability
If a multi-tier back-table drape is designed to cover all surfaces, then comprehensive sterility protection is achieved, but the time required for deployment increases
Solution Approach 1:
The drape portions are pre-configured and connected in a specific arrangement before deployment. The vertical panel is pre-attached to both the lower and upper surface covers, allowing a single technician to deploy the entire drape in a sequential manner without needing to make connections during the deployment process, thus reducing deployment time while maintaining comprehensive sterility protection.
3Reliability
If multiple technicians are assigned to deploy the drape, then proper sterility maintenance is ensured, but personnel costs and overhead increase
Solution Approach 1:
The drape design enables a single technician to perform the entire deployment process independently. The connected fabric portions and vertical panel allow the technician to self-manage the deployment sequence, lifting and positioning each portion in turn without requiring assistance from additional personnel, thus reducing overhead costs while maintaining sterility standards.
4Device complexity
If a single contiguous fabric is used, then the drape structure is simplified, but it may not accommodate various table sizes and shapes
Solution Approach 1:
The contiguous fabric is segmented into multiple portions that can be independently sized and shaped. Each fabric portion can be tailored to fit specific table surfaces (lower table, upper table, vertical space) while remaining connected as a single drape unit. This allows the overall structure to remain simple while adapting to various table configurations and sizes.
Solution Approach 2:
The drape extends into multiple dimensional spaces - covering the lower horizontal surface, the upper horizontal surface, and the vertical space between them. This three-dimensional configuration allows a single contiguous fabric structure to adapt to tables of various sizes and shapes by utilizing vertical space and adjusting the dimensions of each fabric portion independently.

AI summary
A drape suitable for use with a multi-tier back table has a first fabric portion configured to substantially cover a lower table surface and a second fabric portion configured as a pocket that receives at least a substantial portion of an upper table surface. By one approach this pocket includes at least one hand slot configured to receive a user's hand such that the user can lift the second fabric portion and slide the pocket over the upper table surface. A third fabric portion having a vertical panel connects the first and second fabric portions.
