Multi-Ply Medical Drape with Release Liner and Carrier Lift Tab
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical/surgical drapes are not optimized for ease of handling and functionality, particularly in maintaining a sterile field during procedures, as they can be cumbersome and lack innovative features for secure application and removal.
Innovation Solution
A multi-ply medical drape design featuring a bottom ply as a release liner, a middle ply with adhesive for patient adherence, and a top ply for easy removal, incorporating specific cuts and tabs for secure application and removal, along with optional features like stretchability, access ports, and a non-adhesive wound covering sheet for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a multi-ply film structure with release liner, adhesive middle ply, and carrier ply is used, then the drape can be easily applied and removed while maintaining sterile field, but the device complexity increases due to multiple plies and cuts
Solution Approach 1:
The drape is divided into multiple functional plies (release liner, adhesive middle ply, carrier ply) that can be separately handled and applied. The release liner is peeled away first, then the carrier ply is removed after application, leaving only the adhesive middle ply on the patient. This segmentation allows for easy application and removal while maintaining sterility.
Solution Approach 2:
The carrier ply acts as an intermediary that facilitates application of the adhesive middle ply to the patient while protecting the adhesive properties during handling. The release liner serves as another intermediary that protects the adhesive middle ply before use. These intermediary layers are removed in sequence to achieve the desired result.
2Ease of operation
If tabs and cuts are added for removing plies, then the ease of operation improves, but the manufacturing precision requirements increase
Solution Approach 1:
The drape includes pre-cut tabs that extend through specific plies, allowing users to easily grasp and remove the release liner and carrier ply without touching the adhesive middle ply. These tabs are strategically positioned and sized to provide optimal handling while maintaining manufacturing feasibility.
3Adaptability or versatility
If the adhesive middle ply is stretchable, then the adaptability to patient anatomy improves, but the reliability of maintaining sterile field may be compromised
Solution Approach 1:
The adhesive middle ply is formulated with specific elastic properties that allow it to stretch and conform to various patient anatomies while maintaining its adhesive characteristics and sterile barrier function. The material parameters are carefully selected to balance stretchability with reliability.
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 design enhances ease of handling and application, maintains a sterile field effectively, allows for secure and efficient removal of the drape during procedures, and provides additional features like stretchability and wound management, improving overall procedural efficiency and patient care.
Implementation Method 1
The middle ply has an adhesive applied to its bottom surface to removably adhere the bottom ply to the middle ply

AI summary
A medical drape comprises at least a bottom ply in the form of a release liner, a middle ply which is adhered to the patient during use of the drape, and a top ply covering the middle ply. The middle ply having an adhesive applied to a bottom surface thereof to removably adhere the bottom ply to the middle ply. The drape comprises a drape body defining top and bottom edges and first and second side edges; a first liner release tab and a carrier lift tab, both tabs being at an edge of the body. The first liner release tab is operable to remove the bottom ply from the middle ply to expose the adhesive of the middle ply. The carrier lift tab is operable to remove the top ply from the middle ply after application of the middle ply to a patient.
