Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compression devices that apply pressure orthogonal to the biological surface, such as those described in Japanese Patent Application Publication No. 2005-521464, struggle to effectively narrow or obstruct perforations at puncture sites, hindering efficient hemostasis.
Innovation Solution
A compression device with a rotatable compression portion supported by a hinge mechanism, allowing it to compress the biological surface in a direction intersecting the perforation, facilitated by an inflatable pressing portion and a main body with adhesion capabilities, enabling targeted hemostasis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compression is applied in a direction substantially orthogonal to the biological surface, then the compression device can be结构简单 (simple structure), but it is difficult to narrow or obstruct the perforation at the puncture site, reducing hemostasis effectiveness
Solution Approach 1:
The compression portion is designed to be rotatable around a rotational axis relative to the main body portion, transitioning from a static orthogonal compression structure to a dynamic structure that can adjust compression direction. This rotational capability allows the compression force to be applied in a direction intersecting the perforation, thereby improving hemostasis effectiveness without significantly increasing overall device complexity
Solution Approach 2:
The invention introduces a rotational dimension to the compression mechanism, allowing the compression portion to move from a single orthogonal direction to multiple directions that can intersect the perforation. This dimensional change enables the compression force to be oriented along the perforation path, significantly improving hemostasis while maintaining relatively simple device structure through the use of a hinge portion
2Reliability
If a rotatable compression portion with hinge mechanism is used to compress in a direction intersecting the perforation, then hemostasis effectiveness is improved, but the device structure becomes more complex
Solution Approach 1:
The compression device is segmented into distinct functional portions: a main body portion for fixation, a hinge portion for rotational support, and a compression portion for applying compressive force. This segmentation allows each component to perform its specific function efficiently, with the hinge portion enabling rotational movement and the compression portion delivering targeted compression along the perforation path, thereby improving perforation obstruction capability while keeping each individual component relatively simple
Solution Approach 2:
The hinge portion acts as an intermediary mechanism between the main body portion and the compression portion, enabling rotational movement without requiring a completely complex mechanical system. This intermediary hinge structure facilitates the transmission of compressive force in an intersecting direction while maintaining device simplicity through a straightforward rotational joint design
