Compression Patch Alignment Around Medical Insertion Sites
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compression devices struggle with efficiently aligning a bladder to a predetermined compression position on a biological surface, leading to inefficiencies in wound compression after medical procedures.
Innovation Solution
A compression device with an adhesive sheet and compression member featuring a receiving portion and identification markers that facilitate easy positioning on a biological surface, allowing for precise alignment of the device over wounds or insertion sites.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flexible web with adhesive layer is used to hold the bladder against the skin, then the bladder can be secured to the biological surface, but the efficiency of aligning the bladder to the predetermined compression position is insufficient
Solution Approach 1:
The patent applies visual markers or color-coded indicators on the flexible web and bladder assembly to guide proper positioning. These visual cues enable healthcare providers to quickly and accurately align the bladder with the compression position on the biological surface, eliminating the need for complex alignment procedures while maintaining secure attachment.
2Force
If the bladder is inflated to compress the wound, then hemostasis is achieved, but the positioning accuracy of the compression device is compromised without alignment markers
Solution Approach 1:
The patent introduces alignment markers as an intermediary element between the bladder and the biological surface. These markers serve as a reference system that guides the positioning of the compression device before inflation, ensuring that the compression force is applied at the correct location. The markers act as a mediator that translates the intended compression position into accurate physical placement of the bladder.
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
Enables easy and accurate placement of the device at the appropriate position, ensuring effective wound compression and hemostasis, even when medical insertion members extend outside the body.
Implementation Method 1
one surface of the flexible web is provided with an adhesive layer that adheres to the skin of the patient
Implementation Method 2
an inflatable bladder having a deflated state in which a membrane is adjacent to an end wall and an inflated state in which the membrane is spaced from the end wall

AI summary
A compression device according to this disclosure 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 to be extendable in the thickness direction. 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 to the receiving portion, an identification portion configured to be visually identified in the plan view seen in the thickness direction.
