Placental Tissue Assembly with Translucent Backing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Placental tissue layers used in wound treatments are difficult to distinguish and handle due to their thin, translucent nature, leading to issues like wrinkling and reduced surface contact when rehydrated, as they tend to cling to themselves like plastic film.
Innovation Solution
A placental tissue assembly with a backing material adhered to one side, allowing the backing to be released while the tissue adheres to the wound, featuring a permeable or open mesh design to facilitate easy handling and application without wrinkles, and optionally including a releasable peel-off cover for enhanced ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If placental tissue is made into a single thin layer for wound treatment, then the tissue can be applied to wounds, but it becomes difficult to distinguish sides and handle during application
Solution Approach 1:
A translucent backing material is introduced as an intermediary carrier that supports the thin placental tissue layer during handling and application. The backing material provides mechanical strength and ease of manipulation while allowing visualization of the tissue through its translucent property. After application, the backing material is peeled away, leaving the thin tissue layer adhered to the wound surface.
2Reliability
If placental tissue is rehydrated before application, then it can adhere to the wound surface, but it clings to itself like plastic film causing wrinkles and reducing surface contact
Solution Approach 1:
The translucent backing material serves as a separator that prevents the rehydrated placental tissue from clinging to itself during application. By maintaining the tissue on the backing material until the moment of application, the backing prevents self-adhesion and wrinkling. The tissue is then transferred to the wound surface where it adheres properly without the wrinkling problem.
3Loss of information
If embossing or labels are added to distinguish tissue sides, then side identification is possible, but the tissue becomes more complex and harder to handle
Solution Approach 1:
The translucent backing material provides inherent visual differentiation between sides through its optical properties. The backing material's translucency allows light to pass through, creating natural visual cues that help distinguish the tissue side from the backing side without requiring additional embossing or labels. This local optical property solves the identification problem while maintaining simplicity.
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 ensures the placental tissue adheres firmly to the wound while the backing material is easily removed, maintaining unwrinkled application and improved surface contact, enhancing the handling and application process of thin placental tissue layers.
Implementation Method 1
The backing material is adhered to and covers one of either the first or second sides of the one or more layers of placental tissue
Implementation Method 2
the backing material is permeable to liquids and wherein moistening of the backing material reduces the adherence to the first or second side of the one or more layers allowing the backing material to release from the one or more layers

AI summary
A placental tissue assembly for treating wounds or surfaces of a patient has one or more layers of placental tissue and a backing material. The one or more layers of placental tissue have a first side and a second side. The backing material is adhered to and covers one of either the first or second sides of the one or more layers of placental tissue to create the assembly. The assembly when applied onto a surface to be treated on the side of the tissue opposite the backing material adheres to the surface with an attachment force greater than an attachment force of the backing material adhered to the first or second side. This allows the backing material to be released leaving the placental tissue affixed to the surface to be treated.
