Surgical Drape Geometric Alignment Fluid Control Pouch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical drapes with pre-attached fluid control pouches can be ineffective when the drape is affixed in non-optimal rotational orientations, leading to compromised fluid collection and retention, while user-attachable pouches lack the strength and durability of pre-attached bonds, and may allow fluid leakage due to inadequate attachment to the top surface.
Innovation Solution
A fenestrated surgical drape with a base panel, intermediate panel, and mounting panel, where the panels are aligned and joined with a continuous fluid impervious seal surrounding the fenestration, providing a stronger adhesive bond and improved fluid flow into the attachable fluid control pouch, which has geometric features for intuitive positioning and orientation, ensuring effective fluid collection regardless of drape orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a user-attachable pouch is attached to the drape's absorbent top layer with adhesive, then flexibility and customization are improved, but bond strength and fluid leakage resistance deteriorate
Solution Approach 1:
The drape is divided into multiple functional layers: a fluid-repellent outer layer and an absorbent inner layer. The pouch is attached to the fluid-repellent outer layer rather than the absorbent inner layer, creating distinct functional zones that prevent fluid from penetrating between layers while maintaining strong adhesive bonding.
Solution Approach 2:
The fluid-repellent outer layer acts as an intermediary barrier between the adhesive and fluid exposure. This layer provides a stable attachment surface for the pouch while preventing fluid from reaching the adhesive interface, thereby maintaining both bond strength and fluid leakage resistance.
2Adaptability or versatility
If the drape is affixed in non-optimal rotational orientations, then adaptability to different surgical configurations is improved, but fluid collection effectiveness deteriorates
Solution Approach 1:
The pouch attachment system is designed to function effectively regardless of the drape's rotational orientation. By attaching the pouch to the fluid-repellent outer layer with proper geometric alignment features, the system maintains reliable fluid collection and containment in various orientations, making it universally applicable to different surgical configurations.
Solution Approach 2:
Geometric alignment features are incorporated into both the pouch and drape to provide intuitive positioning and ensure proper orientation. These asymmetric features guide correct placement while maintaining fluid collection effectiveness across different rotational configurations.
3Quantity of substance
If absorbent materials are attached to the drape surface to absorb runoff fluid, then fluid absorption is improved, but saturation and leakage risk increase
Solution Approach 1:
Instead of attaching absorbent material to the outer surface to catch fluid, the invention inverts the approach by attaching a fluid control pouch to the fluid-repellent outer layer. This allows the pouch to directly receive and contain fluid that would otherwise penetrate to the absorbent layer, preventing saturation and leakage while maintaining adaptability.
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
The solution enhances the attachment interface between the pouch and drape, providing a stronger, more durable bond and improved resistance to fluid leakage, ensuring reliable fluid collection and containment even when the drape is not optimally oriented, thus maintaining a sterile environment and preventing contamination.
Implementation Method 1
The base panel, the intermediate panel, and the mounting panel are collectively joined together by a continuous fluid impervious seal surrounding the fenestration
Implementation Method 2
The mounting panel top surface is capable of achieving a higher quality adhesive bond with the fluid control pouch at the attachment interface

AI summary
A surgical drape having an attachable fluid control pouch and geometric alignment feature are described. The surgical drape may be fenestrated and include a base drape panel, an absorbent intermediate panel, and a mounting panel. The mounting panel may have a fluid impervious top surface that forms a higher quality adhesive seal with the adhesive attachment areas of the fluid control pouch. The surgical drape panels may be joined together by a continuous fluid impervious seal surrounding the fenestration. The fluid control pouch attachment edge may include a geometric structure that aligns with a corresponding geometric structure of the fenestration such that the fluid control pouch can be effectively positioned regardless of its rotational orientation relative to the surgical drape.
