Hemostasis Band with Inflatable Compartments for Irregular Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hemostasis bands often migrate on irregular or tapered body surfaces, reducing their effectiveness and causing discomfort due to uneven force distribution and poor fit, leading to potential bleeding and complications.
Innovation Solution
A hemostasis band with inflatable compartments along its edges or perimeter to enhance fit and comfort, directing pressure effectively to the vascular access site by distributing force over a larger area and maintaining proper orientation of the compression element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional hemostasis band is used on irregular or tapered body surfaces, then the device structure remains simple, but the band migrates and loses effectiveness
Solution Approach 1:
The band is divided into multiple segments including a compression element section and a distal section with inflatable compartments. This segmentation allows the distal section to adapt to irregular body surfaces while the compression element maintains hemostatic pressure, preventing migration and improving reliability without excessive complexity.
Solution Approach 2:
The band incorporates inflatable compartments that can be dynamically adjusted by injecting or removing fluid. This dynamic adjustment allows the band to adapt to different body surface geometries and maintain optimal positioning, preventing migration and ensuring continuous hemostatic effectiveness.
2Object-affected harmful factors
If a traditional hemostasis band is used to apply pressure to the access site, then hemostasis can be achieved, but the band digs into the patient's skin causing discomfort
Solution Approach 1:
The band features differentiated local qualities with inflatable compartments in the distal section that distribute pressure over a larger surface area, reducing skin discomfort. The compression element section maintains localized high pressure for effective hemostasis, thus resolving the contradiction between comfort and effectiveness.
Solution Approach 2:
The inflatable compartments act as an intermediary between the band and the patient's body surface. They distribute the mechanical load over a larger area, reducing pressure concentration and skin discomfort, while still allowing the compression element to deliver effective hemostatic pressure at the access site.
3Adaptability or versatility
If the band is made to fit various body shapes, then comfort and fit are improved, but the device complexity increases
Solution Approach 1:
The band is designed with multi-functionality, where the inflatable compartments serve dual purposes: improving anatomical fit across various body shapes and preventing band migration. This universal design approach enhances adaptability without proportionally increasing complexity, as the same structural elements address multiple problems.
