Solution Overview

Problem

Current hemostasis devices for vascular procedures lack a feedback mechanism to ensure consistent compression over the artery, leading to variability in compression force and increased risk of bleeding, hematomas, or radial artery occlusion.

Innovation Solution

A device with a circumferential band or wrap that applies pressure over the wound, incorporating an audible/tactile feedback mechanism to indicate the desired compression force, ensuring consistent securement and compression.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If direct pressure is applied manually by a clinician to stop bleeding after vascular procedures, then hemostasis can be achieved, but the pressure application is inconsistent and variable leading to bleeding, hematomas, or radial artery occlusion

Engineering Contradiction:

Improvehemostasis reliabilityVSAvoidcompression force consistency

Core Design Contradiction:

ReliabilityVSMeasurement precision

Solution Approach 1:

The device incorporates an audible/tactile feedback mechanism that provides real-time information to the clinician about the compression force level. The feedback loop allows the clinician to adjust the band tightness to achieve the desired compression force, ensuring consistent and reliable hemostasis while avoiding excessive compression that could cause radial artery occlusion.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent replaces manual mechanical pressure application with an inflatable balloon system that uses gas pressure to apply consistent compression. The balloon inflation mechanism provides more precise and controllable compression force compared to manual band tightening, while the audible/tactile feedback mechanism further enhances the precision of compression force application.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Force

If a circumferential band with inflatable balloon is used to create compression, then compression force can be applied, but there is significant variation in band securement tightness creating massive variation in compression force

Engineering Contradiction:

Improvecompression forceVSAvoidcompression force uniformity

Core Design Contradiction:

ForceVSMeasurement precision

Solution Approach 1:

The audible/tactile feedback mechanism provides real-time information about the compression force level to the clinician. This feedback loop allows the clinician to adjust the band securement tightness dynamically during inflation to achieve uniform compression force distribution, eliminating the variation caused by inconsistent initial band application.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The device allows dynamic adjustment of the band securement tightness during the compression process. The clinician can modify the band application based on real-time feedback from the audible/tactile mechanism, enabling the system to adapt to variations in patient anatomy and achieve uniform compression force despite initial variations in band securement.

Inventive Principle:

Principle #15Dynamics

3Force

If tighter band securement is applied prior to inflation, then more compression is created with the same volume of air, but this creates excessive compression force that may result in radial artery occlusion

Engineering Contradiction:

Improvecompression forceVSAvoidradial artery occlusion risk

Core Design Contradiction:

ForceVSObject-affected harmful factors

Solution Approach 1:

The audible/tactile feedback mechanism provides real-time information about the compression force level to the clinician. This feedback loop allows the clinician to monitor the compression force during balloon inflation and adjust the securement tightness accordingly, preventing excessive compression that could cause radial artery occlusion while still achieving sufficient compression for hemostasis.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The device allows the clinician to apply partial securement initially and then adjust based on feedback during inflation. Rather than applying maximum securement beforehand, the system enables progressive adjustment to achieve the optimal compression level, avoiding excessive compression while ensuring sufficient hemostasis.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

An audible and/or tactile feedback hemostasis compression device employs a mechanism that produces a sound or tactile response when sufficient force is applied atop a wound post vascular procedure and applies proper hemostasis compression. This device can be used with circumferential bands, manual pressure, or other mechanical compression devices to create more uniform band securement, resulting in more uniform wound compression.
