Engineering Contradiction:

Improveuser convenienceVSAvoidapplication flexibility

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent designs the catheter and syringe assembly to be universally compatible with various CO2 sources and delivery configurations, allowing the same basic apparatus to be used for different medical applications and patient scenarios without requiring specialized components

Inventive Principle:

Principle #6Universality (Multi-functionality)

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 apparatus provides a safer, more convenient, and cost-effective means to produce and deliver enriched medical suspensions of carbon dioxide, reducing the risk of malfunctions and improving medical procedures by alleviating patient discomfort and simplifying practitioner use.

Implementation Method 1

The present invention utilizes the Venturi effect to produce an enriched medical suspension of carbon dioxide (CO2)

Methodology Applied

Scientific EffectVenturi effect: Venturi Effect

Implementation Method 2

The fluid velocity must increase through the constriction to satisfy the equation of continuity, while its pressure must decrease due to conservation of energy; the gain in kinetic energy is supplied by a drop in pressure or a pressure gradient force

AI summary

A medical fluid suspension generating apparatus for performing medical procedures includes a Venturi-agitating tip assembly composed of a multi-channel arrangement at a proximal first end thereof and a tip at a distal second end thereof. The apparatus also includes a compressed medical fluid unit fluidly connected to the multi-channel arrangement at a proximal first end of the Venturi-agitating tip assembly and a medical solution fluidly connected to the multi-channel arrangement at a proximal first end of the Venturi-agitating tip assembly. Pressurized gas, from the compressed medical fluid unit, and the medical solution are combined within the Venturi-agitating tip assembly in a manner generating an enriched medical suspension that is ultimately dispensed from the suspension delivery apparatus.
