Bedsore Prevention Pad With Observation Lid and Exudate Barrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bedsores prevention technologies fail to effectively prevent the development of bedsores due to exudate or excrement permeation, and lack ease of observation and replacement, leading to increased risk and treatment frequency.
Innovation Solution
A modified member with a lid cover having a larger area than the lid, featuring a stacked structure of a pressure-sensitive adhesive layer, release material layer, and protective layer, allowing easy attachment and detachment, and a central opening for observation and replacement, along with a pad layer to absorb exudate and reduce pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a diaper cover is used to absorb urine and collect excrement, then excrement can be contained within the diaper, but the lid cannot be easily opened or closed for observation and replacement
Solution Approach 1:
The lid assembly is segmented into distinct functional layers: the lid cover (with adhesive layer for attachment), the lid body (with opening for observation), and the release material layer (for easy detachment). This segmentation allows each component to perform its specific function independently, enabling easy opening and closing without complex mechanisms.
Solution Approach 2:
The adhesive layer is pre-applied to the lid cover, and the release material layer is pre-positioned on the adhesive layer. This preliminary preparation allows the lid to be easily attached to and detached from the diaper cover by simply peeling the release material, without requiring complex fastening mechanisms or tools.
2Area of stationary object
If the lid area is increased to allow better observation of affected skin, then visual inspection is improved, but the lid becomes harder to handle and replace
Solution Approach 1:
The lid system is divided into a larger lid cover that provides extensive observation area, and a separate adhesive layer with release material that enables easy handling. The adhesive layer is positioned at the periphery of the lid cover, allowing the user to grip and manipulate the lid without interfering with the large observation area.
Solution Approach 2:
The adhesive layer acts as an intermediary between the lid cover and the diaper cover, providing a simple attachment mechanism. The release material on the adhesive layer serves as a mediator that facilitates easy detachment, allowing the large lid to be replaced without requiring complex fastening or manual dexterity.
3Reliability
If excrement collection capability is enhanced to prevent bedsores, then bedsore prevention is improved, but excrement may still permeate and contact the sacral region
Solution Approach 1:
The lid cover, lid body, and adhesive layer are merged into a single integrated assembly that combines observation, containment, and attachment functions. This unified structure ensures that excrement is contained within the diaper while the lid provides continuous protection over the sacral region, preventing permeation and contact with harmful substances.

AI summary
The present invention relates to a modified member for preventing bedsores, which comprises a stacked body composed of: a pad layer (10) of a synthetic resin film formed from synthetic resin foam and hydrocolloid or hydrogel, so as to come into direct contact with a patient's skin; a cover layer (20) of a synthetic resin film, which is integrally stacked on the outer surface of the pad layer (10); and a pressure-sensitive adhesive layer (30) formed on the inner surface of the cover layer (20) and having a pressure-sensitive adhesive applied thereon, characterized in that the modified member comprises: an opening (50) penetratingly formed at a central portion thereof to allow an affected part of the patient's skin to be observed with naked eyes therethrough: a lid (40) disposed at the opening to correspond to the shape of the opening (50) so that the lid can be opened/closed relative to the opening (50) by press-fit engagement; and a lid cover (90) disposed on the upper outer surface of the lid (40) and having an area larger than that of the lid.
