Peelable Adhesive Operating Drape for Tool-Free Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing impermeable operating drapes with windows pose challenges for removal without tools or tears, as they either require cutting or tearing, which complicates surgical procedures and risks tubes, wires, or lines, and existing solutions like tear lines or weakening do not ensure impermeability.
Innovation Solution
A drape composed of two impermeable sheets joined by adhesive, allowing separation by peeling, with a shared window and absorbent strips to facilitate removal without tools and maintain impermeability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drape is made impermeable to ensure infection prevention, then reliability is improved, but ease of operation deteriorates because cutting or tearing tools are required for removal
Solution Approach 1:
The drape is divided into two separate impermeable sheets (first sheet and second sheet) that are joined by adhesive. This segmentation allows the sheets to be separated by peeling without requiring cutting or tearing tools, while each sheet individually maintains impermeability when attached to the patient's body.
Solution Approach 2:
An adhesive layer is introduced as an intermediary between the two impermeable sheets. This adhesive allows the sheets to be easily separated by peeling during removal, while during use it maintains the integrity and impermeability of the drape structure.
2Ease of operation
If tear lines or weakening are added to facilitate drape removal, then ease of operation is improved, but reliability deteriorates because impermeability is compromised and accidental perforations occur
Solution Approach 1:
Instead of adding tear lines to a single sheet, the drape is segmented into two complete impermeable sheets. The separation interface is created through the adhesive layer rather than through perforations or weakenings in the impermeable material itself, thus maintaining integrity.
Solution Approach 2:
The adhesive acts as the intermediary that enables separation without compromising the impermeable nature of the drape material. The adhesive layer is designed to be separable by peeling while the impermeable sheets themselves remain intact and impermeable.
3Ease of operation
If cutting or tearing operations are performed during drape removal, then ease of operation is improved, but device complexity increases and risks to tubes and lines are created
Solution Approach 1:
The drape structure enables its own removal through the peeling action of separating the two sheets. This self-service mechanism eliminates the need for external cutting or tearing tools and operations, reducing complexity and eliminating risks to medical instruments.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy and reliable removal of the drape without tools, ensuring impermeability and reducing risks to tubes and lines during surgical procedures.
Implementation Method 1
the web is composed of two impermeable sheets (10, 20) arranged in extension of each other in a sealed manner by an adhesive that allows separation of the sheets by peeling them apart

AI summary
The invention relates to an operating drape formed by an impermeable web that has a window (3) for access to the operating site, characterized in that the web consists of two impermeable sheets (10,20) held together, one along the extension of the other, in a sealed manner by an adhesive that allows the sheets to be separated by peeling and in that the window (3) is shared between the two sheets. The invention applies in particular to operating drapes used in surgery.
