Solution Overview

Problem

Current IV fluid bags lack a mechanism to notify medical personnel of prior injections, risking the infusion of contaminated or improperly medicated fluids due to the self-sealing material's inability to indicate punctures.

Innovation Solution

Incorporating an object or sealed chamber within the injection port that alters appearance upon needle penetration, providing visual notification of prior use through inflation/deflation, color change, or fluid interaction, ensuring medical personnel are aware of previous injections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a self-sealing material is used in the injection port to prevent leakage, then the sealing reliability is improved, but the ability to indicate prior puncture is lost

Engineering Contradiction:
Improvesealing reliabilityVSAvoidpuncture indication
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

A balloon is nested inside the injection port housing, surrounding the self-sealing material. The balloon serves as an inner indicator system that is activated when the outer self-sealing membrane is punctured, allowing the balloon to expand and provide visual indication while the self-sealing material maintains its sealing function

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The balloon acts as an intermediary element between the puncture event and the visual indication. When the needle punctures the self-sealing membrane, it simultaneously punctures the balloon, causing the balloon to expand and provide visual feedback without compromising the self-sealing function of the original membrane

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If no indicator mechanism is added to the injection port, then the device complexity is reduced, but the ability to notify medical personnel of prior use is lost

Engineering Contradiction:
Improveinjection port structureVSAvoidprior use notification
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The balloon provides a visual color change indication when activated. The expansion of the balloon creates a visible color change or opacity change that can be easily observed by medical personnel, providing clear notification of prior use without requiring complex electronic or mechanical systems

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The indicator mechanism utilizes the spatial dimension within the injection port housing by placing the balloon in a collapsed state initially and allowing it to expand into the available space when activated. This three-dimensional transformation provides clear visual indication without adding significant external complexity to the injection port structure

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

The present invention monitors an IV bag injection port and informs the user of prior injections. The present invention employs an object and/or a sealed chamber within a transparent IV fluid bag injection port. In the case of the object, notification of prior use is achieved when the object's or IV fluid's appearance is altered. With respect to the sealed chamber, the chamber's seal is breached to allow fluid to pass between the chamber and the IV bag to change the appearance of the contents of the chamber. Since the injection port and bag walls are at least partially transparent, medical personnel are able to observe the altered appearance of either the object, IV fluid or the sealed chamber.
