Medical Dressing Carrier System for Wrinkle-Free Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dressings face challenges with wrinkling, crumpling, and reduced adhesive properties when applied to skin, especially when pharmaceutical substances are applied to the skin surface before dressing, leading to early separation of the dressing from the application site.
Innovation Solution
A carrier system with a gripping section and a protective sheet that allows for precise application of dressings without wrinkling, featuring a supporting section and a protective sheet with openings for controlled substance application, ensuring the dressing adheres effectively to the skin by separating the dressing from the carrier system at a lower force than required for skin adhesion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a thin film adhesive coated dressing is applied directly to the skin, then the dressing can be easily applied, but it wrinkles and crumples during application and loses adhesive properties
Solution Approach 1:
The invention divides the dressing into two separate components: a thin film adhesive coated dressing sheet and a separate carrier system. This segmentation allows the dressing sheet to remain thin and flexible while the carrier system provides structural support during application, preventing wrinkling and crumpling. The dressing sheet can be easily applied as it adheres directly to the skin, while the carrier system maintains reliability by providing a rigid base that prevents deformation during the application process.
2Adaptability or versatility
If pharmaceutical substances are applied to the skin surface before dressing, then the substance can be delivered to the application site, but the adhesive properties of the dressing are reduced and it separates early
Solution Approach 1:
The invention segments the delivery system into a dressing sheet with adhesive properties and a separate carrier system that can accommodate pharmaceutical substances. The carrier system includes a cavity or compartment where pharmaceutical substances can be placed without interfering with the adhesive coating on the dressing sheet. This allows the substance to be delivered to the application site while the adhesive properties remain intact, preventing early separation.
Solution Approach 2:
The carrier system acts as an intermediary between the pharmaceutical substance and the adhesive dressing sheet. The carrier system provides a platform for substance application while protecting the adhesive properties of the dressing sheet. The substance can be applied to the carrier system or in the cavity, and the dressing sheet is then applied to the skin, maintaining its adhesive integrity.
3Reliability
If the carrier system provides strong support for the dressing sheet, then wrinkling is prevented, but the carrier system becomes difficult to handle and separate from the dressing
Solution Approach 1:
The carrier system is designed with dynamic characteristics that allow it to be rigid during application to prevent wrinkling, but flexible enough to be easily handled and separated. The carrier system may include features such as a hinge connection or a breakable bond that allows it to transition from a supportive rigid structure during application to a separable component after application. This dynamic design maintains support stability while improving ease of handling.
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 prevents wrinkling and crumpling of dressings during application, maintains adhesive properties, and allows for controlled and accurate application of pharmaceutical substances, ensuring the dressing remains adhered to the skin for a longer duration.
Implementation Method 1
a dressing sheet, one first surface of which is provided with an adhesive, whereby said first surface defines an adhering surface for attaching the dressing sheet to an anatomical surface of a living being

AI summary
A dressing product comprises a dressing sheet (102), such as a thin film, one first surface of which is coated with an adhesive (106), such as a pressure sensitive hydrocolloid adhesive, which is applicable to an anatomical surface of a living being, such as a skin portion of a human. A carrier system, which provides a support for the dressing sheet, defines a gripping section for handling of the carrier system by human fingers. The carrier system may include one or more foil members (216;218;220;222) and supporting sheets (212) for facilitating application and for providing a non-touch application system, i.e. a system which may be handled by an operator without the operator touching the dressing sheet (102) or at least the adhesive surface (106) thereof. A protective sheet having an opening for application of a pharmaceutical product to the adhesive prior to application of the dressing sheet is disclosed.
