Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Achieving effective hemostasis at vascular access puncture sites, particularly in areas like the wrist, hand, and foot, is challenging due to the need for precise alignment and application of pressure to prevent blood leakage and promote healing.
Innovation Solution
The development of an inflatable hemostasis device with a transparent compression member and alignment indicia, which facilitates accurate alignment over the puncture site, reduces the parallax effect, and applies controlled compression to ensure effective hemostasis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compression is applied at the puncture site to achieve hemostasis, then blood leakage is reduced, but precise alignment is difficult to achieve
Solution Approach 1:
Alignment indicia are introduced as intermediary visual markers on the compression device that mediate between the device structure and the puncture site, enabling precise alignment through visual reference without requiring direct measurement or complex positioning mechanisms
Solution Approach 2:
The alignment indicia utilize visual contrast (color or transparency differences) to create easily distinguishable markers that facilitate rapid and accurate alignment of the compression device with the puncture site, improving measurement precision through optical differentiation
2Ease of operation
If the compression member is made transparent to improve visualization, then alignment is facilitated, but the structural strength may be reduced
Solution Approach 1:
The compression member is constructed from composite materials that combine transparency with sufficient structural strength, allowing simultaneous achievement of visualization capability and mechanical integrity through material composition rather than sacrificing one property for the other
3Manufacturing precision
If the device is made complex with multiple components to improve compression control, then hemostasis precision is improved, but device complexity increases
Solution Approach 1:
The compression device is segmented into distinct functional components (compression member, alignment indicia, inflation mechanism) that can be independently manufactured and assembled, allowing precise control of compression through modular design while managing overall device complexity through standardized interfaces

AI summary
An inflatable compression device configured to apply a compressive force to a puncture site of a patient's vessel, such as an artery is disclosed. The hemostasis device may comprise a location indicium disposed on an inside surface of an inflatable bladder portion of the device so as to be disposed in close proximity to the skin of the patient to improve alignment of the compression device with the puncture site.
