Solution Overview

Problem

Existing compression devices struggle with efficient alignment of the bladder to a predetermined compression position on a biological surface, necessitating improved positioning and adherence to medical insertion members.

Innovation Solution

A compression device with an adhesive sheet and a compression member featuring a pressing body and holding body, including a receiving portion for medical insertion members and identification markers for precise alignment, allowing easy positioning and adherence to biological surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a flexible web with adhesive layer is used to hold the bladder against the skin, then the bladder can be adhered to the biological surface, but the alignment efficiency of the bladder to the predetermined compression position is insufficient

Engineering Contradiction:
Improveadhesion reliabilityVSAvoidalignment efficiency
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies visual markers (colored regions or patterns) on the adhesive sheet and corresponding alignment markers on the biological surface to guide proper positioning. These visual indicators enable quick and accurate alignment of the bladder with the compression position, resolving the contradiction between reliable adhesion and easy alignment by adding a visual guidance system without compromising the adhesive function.

Inventive Principle:
Principle #32Color changes

2Reliability

If the adhesive sheet covers the entire area including the receiving portion, then the device adheres firmly to the skin, but the medical insertion member cannot be properly received and aligned

Engineering Contradiction:
Improveadhesion strengthVSAvoidreceiving portion functionality
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The adhesive sheet is designed with a local quality variation: it covers most of the holding body area to ensure firm adhesion, but deliberately leaves the receiving portion area uncovered or with reduced adhesion. This localized difference in adhesive coverage allows the medical insertion member to be properly inserted and aligned in the receiving portion while maintaining strong overall adhesion of the device to the skin through the surrounding adhesive areas.

Inventive Principle:
Principle #3Local quality

3Measurement precision

If visual identification features are added to improve positioning accuracy, then the alignment precision improves, but the device complexity increases

Engineering Contradiction:
Improvepositioning accuracyVSAvoidstructure complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent incorporates visual identification features in the form of colored markers or patterns printed or applied on the adhesive sheet and corresponding markers on the holding body. These visual features provide clear guidance for alignment without requiring complex mechanical or electronic positioning systems. The markers are simple graphical elements that can be easily manufactured and integrated into the existing device structure, thus improving positioning accuracy while minimizing the increase in device complexity.

AI summary

A compression device includes: an adhesive sheet having an adhesion surface; and a compression member configured to compress a biological surface. The compression member includes: a pressing body configured to press the biological surface by extending in a thickness direction of the adhesive sheet; and a holding body fixed to the adhesive sheet and configured to hold the pressing body. In a plan view seen in the thickness direction, a receiving portion, which is a region in which the adhesive sheet is not disposed or a region defined by a concave portion in an outer edge of the adhesive sheet and which is configured to receive a medical insertion member, is provided outside an outer edge of the holding body. The holding body includes, at a position adjacent the receiving portion, an identification portion configured to be visually identified in the plan view seen in the thickness direction.
