Solution Overview

Problem

Obtaining vascular access is challenging in approximately 5-10% of patients, particularly in emergency situations where traditional IV access is difficult or impossible, leading to delays and complications in treatment.

Innovation Solution

The use of intraosseous (IO) devices and techniques that allow for the stabilization and secure attachment of IO devices in bones, enabling direct access to the vascular system for fluid communication and medication administration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional IV access is used, then vascular access can be obtained, but in 5-10% of patients vascular access cannot be obtained or is difficult to obtain

Engineering Contradiction:

Improvevascular access reliabilityVSAvoidadaptability to different patient conditions

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent introduces bone marrow as an intermediary access point between the external environment and the vascular system. The intraosseous device penetrates the bone to reach the medullary cavity, providing a alternative vascular access route when traditional IV access fails. This intermediary approach allows fluid and medication delivery to the vascular system through a different anatomical pathway.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If central line access is used, then vascular access can be obtained, but it takes longer, costs more, and requires skilled personnel

Engineering Contradiction:

Improvevascular access reliabilityVSAvoidtime for access establishment

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent employs a preliminary action approach by pre-assembling the intraosseous device with all necessary components (needle, hub, connector) in a ready-to-use configuration. The device can be inserted directly into the bone without requiring complex surgical preparation or specialized facilities, enabling rapid access establishment in emergency situations.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent extracts the essential function of vascular access from the complex central line procedure and creates a simplified intraosseous access system. By removing unnecessary complexity and focusing on the core function of establishing vascular access, the procedure can be performed quickly by various healthcare providers without requiring specialized skills or expensive equipment.

Inventive Principle:

Principle #2Taking out (Extraction)

3Productivity

If intraosseous access is used, then rapid vascular access can be obtained, but the device requires stabilization and secure attachment

Engineering Contradiction:

Improvespeed of vascular accessVSAvoiddevice stabilization requirements

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent merges the stabilization function directly into the intraosseous device structure. The hub component integrates both the fluid connection interface and the stabilization mechanism, combining multiple functions into a single unified structure. This integration eliminates the need for separate stabilization devices and simplifies the overall system while maintaining rapid access capability.

Inventive Principle:

Principle #5Merging (Combining)
