Sealed Surgical Drape with Adhesive Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical environments inadequately protect physicians from blood-borne infections, and conventional protective measures are insufficient for preventing both physician and bedside contamination during operations.
Innovation Solution
A flexible, bag-shaped drape with a transparent top and opaque bottom, featuring operation site-revealing openings, hand insertion parts, and a medical device supply port, designed to create a sealed operating space using adhesive sealing means and reinforced medical device supply ports to prevent contamination and infection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional operating gowns and masks are used, then physician protection against patient infection is improved, but physician protection against blood-borne infection is insufficient
Solution Approach 1:
The drape is divided into multiple functional segments: a main body portion covering the operation site, separate hand insertion parts for the physician and assistant, and distinct medical device supply ports. This segmentation allows each part to perform its specific function optimally while maintaining overall protection effectiveness.
Solution Approach 2:
The drape is designed as a disposable single-use device, eliminating the need for complex reusable protective gear that requires maintenance and sterilization. After use, the entire drape is discarded, ensuring complete protection without cross-contamination risks.
2Reliability
If a completely sealed operating space is created, then contamination prevention is improved, but physician access to the operation site is restricted
Solution Approach 1:
The hand insertion parts are extracted as separate functional elements from the main sealed body of the drape. These openings allow the physician's hands to enter the sterile field while the rest of the drape remains sealed, maintaining contamination barriers while enabling necessary access.
Solution Approach 2:
The hand insertion parts act as intermediary elements between the non-sterile external environment and the sterile operating space. They provide a controlled transition zone that allows hand insertion while maintaining the integrity of the sealed operating environment.
3Adaptability or versatility
If multiple openings are provided for hand insertion and device supply, then operational flexibility is improved, but sealed space integrity is compromised
Solution Approach 1:
Different regions of the drape are designed with different properties: the main body maintains complete sealing, while specific localized areas (hand insertion parts and device supply ports) are designed with controlled opening/closing mechanisms. This local differentiation allows flexibility where needed while preserving integrity where critical.
Solution Approach 2:
The hand insertion parts and medical device supply ports are designed to be dynamically openable and closable during the procedure. This dynamic capability allows the drape to transition between sealed and open states as needed, maintaining flexibility while preserving the ability to restore sealing integrity.

AI summary
A drape for clean operation is a flexible bag-shaped structure for maintaining a substantially closed operating space around an operation site. The bag-shaped structure comprises a bottom wall 1 and a transparent top wall 2 and has a closed proximal end 100a and a closed distal end 100b. The bottom wall 1 is provided with at least one operation site-revealing opening 3 close to the proximal end, and the top wall 2 is provided with at least one pair of hand insertion parts 4 at a position close to the operation site-revealing opening 3 to allow the physician to aseptically insert the hands into the operating space, and a closed, openable and closable medical device supply port 5 for supplying medical devices required for operations at a position away from the operation site-revealing opening 3.
