Surgical Table Drape with Adhesive Barrier Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tiered surgical instrument tables are difficult to drape properly due to open gaps between tiers in existing drapes, making installation and removal challenging.
Innovation Solution
A two-tiered surgical table with a sterile fitted drape featuring a drape assembly and a removable sterile barrier with adhesive strips and 'TEAR HERE' decals for easy installation and quick removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fitted surgical drape with multiple sheets is used to cover tiered surgical tables, then coverage of the table tiers is achieved, but open gaps remain on the sides between tiers and proper installation is difficult
Solution Approach 1:
The drape is divided into multiple functional segments: a fitted sheet portion that covers the table tiers, a barrier portion that provides sterile coverage, and adhesive strips that enable secure attachment. This segmentation allows each part to perform its specific function effectively while simplifying the overall installation process.
Solution Approach 2:
Adhesive strips are pre-positioned on the drape at locations optimized for attachment to the surgical table. This preliminary positioning eliminates the need for complex alignment during installation, allowing medical personnel to quickly secure the drape in the correct position without gaps or misalignment.
2Reliability
If traditional draping methods are used, then sterile coverage is provided, but drape removal is time-consuming and complex
Solution Approach 1:
The barrier portion is designed as a removable element that can be easily separated from the fitted sheet portion. This extraction design allows the sterile barrier to be quickly removed after surgery without requiring removal of the entire drape system, significantly reducing the time needed for drape removal while maintaining sterile coverage during the procedure.
Solution Approach 2:
The drape incorporates dynamic elements including removable adhesive strips and a separable barrier portion that can be easily detached. This dynamic design enables quick adjustment and removal of the sterile barrier after use, contrasting with static traditional drapes that require complete removal and complex manipulation.
3Reliability
If adhesive strips are added to the drape, then secure attachment to the table is achieved, but the drape structure becomes more complex
Solution Approach 1:
The adhesive strips are integrated directly into the drape construction, merging the attachment function with the drape structure itself. This combination eliminates the need for separate attachment mechanisms or additional components, securing the drape to the table while maintaining a relatively simple overall structure that is easy to manufacture and use.
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
Simplifies the draping process by providing a seamless coverage of the table tiers with the drape assembly and allows for quick and easy removal of the sterile barrier, enhancing surgical hygiene and efficiency.
Implementation Method 1
A surgical instrument table and drape therefor. The drape includes a drape assembly and a barrier portion with a front surface, a back surface, a first long edge, a second long edge, a first short edge, and a second short edge. The barrier portion has a first adhesive strip attached to the back surface near the first long edge and a second adhesive strip attached to the back surface near the second long edge.

AI summary
A multi-tiered surgical table and a fitted drape for the table are disclosed. The table has a pair of table tops: a rearward, inclined top at a first elevation and a forward top at a lower second elevation. The drape has top panels corresponding in shape to the table tops, with a step panel therebetween to accommodate the change in elevation. The drape is provided, front, top and rear with receptacles for fluids and waste materials and pockets for surgical supplies such as sponges.
