Medical Sensor Supporting Member With Foldable Sheet for Body Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical sensors face challenges in improving convenience during attachment to a subject's body, particularly in exposing and handling the adhesive face for secure and efficient attachment of light emitters and detectors.
Innovation Solution
A medical sensor design featuring a supporting member with adhesive face, a peelable sheet, and a foldable portion that enhances foldability, allowing easy exposure and handling of the adhesive face, facilitating smooth attachment and discarding without multiple peeling operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sheet is completely peeled from the supporting member, then the adhesive face is fully exposed for attachment, but the adhesive face may be excessively exposed and obstruct the attachment operation
Solution Approach 1:
The sheet is pre-formed with a foldable portion that creates a natural stopping point during peeling. This preliminary structural design guides the user to peel only to the appropriate extent, exposing the adhesive face sufficiently for attachment without excessive exposure that would obstruct the operation.
2Ease of operation
If the sheet is peeled multiple times from different edges, then the adhesive face can be fully exposed, but the operation becomes complex and time-consuming
Solution Approach 1:
The foldable portion is pre-configured to create a tab that enables single-edge peeling. This preliminary action design eliminates the need for multiple peeling operations from different edges, allowing the adhesive face to be fully exposed through one continuous peeling motion, thereby reducing operation time and complexity.
Solution Approach 2:
The sheet is segmented into a peeled portion and a remaining portion by the foldable portion. This segmentation allows the peeled portion to serve as a tab for pulling, enabling complete adhesive exposure through a single peeling action rather than multiple incremental peels.
3Stability of the object's composition
If the sheet is made rigid for structural support, then the supporting member maintains its shape, but the sheet cannot be easily peeled and folded
Solution Approach 1:
The sheet has different mechanical properties in different regions: the foldable portion is designed with reduced rigidity to enable peeling and folding operations, while the remaining portions maintain sufficient rigidity to provide structural support and maintain the shape of the supporting member during attachment.

AI summary
At least one light emitter is configured to emit light. At least one light detector is configured to output a signal corresponding to an amount of incident light. A supporting member has an adhesive face adapted to be attached to a body of a subject. A sheet is peelably attached to the adhesive face. The supporting member includes a first supporting portion, a second supporting portion and a third supporting portion. The first supporting portion supports and covers the light emitter. The second supporting portion supports and covers the light detector. The third supporting portion is located between the first supporting portion and the second supporting portion. The sheet is formed with a foldable portion extending across a portion facing the third supporting portion and including a portion whose cross-sectional shape is changed so as to increase foldability of the sheet.
