Modular Surgical Drape with Transparent Radial Attachment for PICC Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical drapes are inadequate for maintaining sterile fields during central catheter insertion procedures, as they require two people to apply and can be compromised by single-person use, leading to potential contamination and infection risks due to improper aseptic techniques and tourniquet application.
Innovation Solution
A modular medical drape system comprising a patient drape and radial drape attachment, which is easy to apply and remove by a single person, featuring a transparent radial attachment for visibility of the arm, integrated tourniquets, and a tool-less removal feature to prevent catheter line disturbance, ensuring aseptic technique and maintaining sterility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional medical drape is used during central catheter insertion, then a sterile field can be established, but two people are required to apply it and sterility can be compromised by single-person use
Solution Approach 1:
The drape is divided into separate components: a main drape body and a transparent radial attachment that can be applied independently to the patient's arm. This segmentation allows the radial attachment to be pre-positioned and secured before the main drape is applied, enabling single-person application while maintaining sterility.
Solution Approach 2:
The transparent radial attachment is designed to be applied to the patient's arm before the main drape is positioned. This preliminary action establishes the arm coverage and tourniquet access points in advance, allowing the operator to then apply the main drape without compromising the already-established sterile field on the arm.
2Reliability
If a conventional opaque drape is used, then sterility is maintained, but visibility of the arm and catheter insertion site is reduced
Solution Approach 1:
The drape system combines opaque material for the main body (maintaining sterility) with a transparent radial attachment covering the arm and insertion site (providing visibility). This local differentiation of material properties allows simultaneous achievement of sterility maintenance and visual access to the procedure site.
3Device complexity
If a conventional drape without integrated tourniquet is used, then drape simplicity is maintained, but tourniquet application and management becomes more complex and may compromise sterility
Solution Approach 1:
The tourniquet is integrated into the transparent radial attachment, combining two separate functions (arm coverage and tourniquet application) into a single component. This merging eliminates the need for separate tourniquet application steps that could compromise sterility, while the transparent material maintains visibility of the insertion site.
4Reliability
If a conventional drape requiring two people for application is used, then sterility can be maintained, but procedure time and resource requirements increase
Solution Approach 1:
The modular design with pre-positionable radial attachment enables a single operator to apply the entire drape system independently. The attachment's adhesive backing and self-contained structure allow one person to secure both the arm coverage and main drape without assistance, reducing procedure time and resource requirements while maintaining sterility.

AI summary
A medical drape includes a patient drape (100) and a radial drape attachment (200). The radial drape attachment can be coupled to the patient drape by way of an adhesive coupling (202). The radial drape attachment includes defines one or more fenestrations (205) or apertures through which a central line may be inserted. Some or all of the radial drape attachment (200) can be transparent or pellucid. Portions of the radial drape attachment can be opaque as well. A support layer can be configured to be absorptive, fluid impenetrable, or both. A tourniquet (1801) may be integrated with the radial drape attachment, as can one or more tool-less removal features (209). Pouches (901,902) can be added to catch fluids or hold medical implements during a procedure.
