Compression Block for Cardiac Device Pocket Bleeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Post-operative pocket bleeding and hematoma formation are significant complications in cardiac device implantations, particularly in patients on anticoagulation therapy, leading to increased hospital stays, infections, and healthcare costs.
Innovation Solution
A medical device comprising a pliable wrap with a solid, non-inflatable compression block applied to the affected area to provide adjustable pressure that hinders blood flow enough to promote clotting while allowing sufficient blood flow for healing, reducing the incidence and severity of hematomas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If compression pressure is increased to stop bleeding, then clotting is promoted, but blood flow for healing is completely prevented
Solution Approach 1:
The device changes the parameter of compression pressure from complete occlusion to controlled reduction, maintaining it within a specific range that hinders blood flow sufficiently to promote clotting while allowing enough flow to support the healing process
Solution Approach 2:
Instead of applying excessive compression that would completely stop blood flow, the device applies partial compression that is sufficient to hinder blood flow and promote clotting while preserving the necessary flow for tissue healing
2Object-affected harmful factors
If compression is applied to reduce hematoma formation, then bleeding is controlled, but patient mobility is restricted
Solution Approach 1:
The device transitions from static compression to dynamic compression that adapts to patient movement, allowing the compression level to vary with activity while maintaining effectiveness in preventing hematoma formation
Solution Approach 2:
The device uses flexible compression garments that can move with the patient's body, providing continuous compression without restricting mobility, unlike rigid compression devices
3Object-affected harmful factors
If compression devices are used to prevent bleeding, then clotting is promoted, but device complexity increases
Solution Approach 1:
The device employs simple, disposable compression components that eliminate the need for complex adjustable mechanisms, reducing overall device complexity while maintaining effective compression for promoting clotting
Solution Approach 2:
The compression device is divided into separate modular components including compression blocks and wrap elements, allowing for simplified assembly and reducing the complexity of any single component
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
The device effectively reduces the incidence and severity of hematomas, shortens hospital stays, decreases the need for repeat interventions, and lowers healthcare costs by allowing patients to manage bleeding and healing without complete blood flow cessation.
Implementation Method 1
a block of solid, non-inflatable material positioned between the wrap and the localized area of the patient... The wrap is secured to cause the wrap to apply a force, to the block, that produces a corresponding pressure on the localized area
Implementation Method 2
The wrap includes an elastic material, such as neoprene for example, and may also include straps to adjust the pressure applied to a localized area on the patient by the block

AI summary
A method mitigates pocket bleeding and hematoma formation in a patient by providing a pliable wrap having a solid block coupled with the wrap, and then securing the pliable wrap around the torso of the patient to align the solid block with the located localized torso area. The solid block at least in part covers the localized torso area. The wrap is secured to cause the wrap to apply a force, to the solid block, that produces a corresponding pressure on the localized torso area. The force applied to the solid block is high enough to cause the pressure to hinder blood flow to the localized torso area to promote clotting at the localized torso area. At the same time, the force applied to the solid block is low enough to cause the pressure to permit blood flow to the localized torso area to promote healing.
