Solution Overview

Problem

Current insufflators require two hands to operate, necessitating a second physician to hold the angioplasty catheter in place during procedures, leading to potential vessel damage or inadequate angioplasty due to divided attention between inflation control and catheter positioning.

Innovation Solution

A single-handed insufflation pump design featuring a syringe mechanism linked to an actuation mechanism via a toggle assembly, allowing one-handed operation with a pistol grip and oscillating lever to control pressure and fluid flow, enabling precise balloon inflation without compromising catheter positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a traditional insufflator is used, then accurate balloon inflation pressure control is achieved, but two hands are required for operation, forcing a second physician to hold the catheter

Engineering Contradiction:
Improveballoon inflation pressure controlVSAvoidnumber of hands required
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent combines the insufflator body and syringe mechanism into a single integrated device, allowing one hand to perform both inflation control and catheter positioning functions simultaneously, eliminating the need for a second physician

Inventive Principle:
Principle #5Merging (Combining)

2Measurement precision

If a second physician is assigned to hold the catheter, then proper catheter positioning is maintained, but the primary physician cannot fully control inflation rates and pressures

Engineering Contradiction:
Improveinflation pressure controlVSAvoidcatheter positioning stability
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The device enables the primary physician to independently control both catheter positioning and balloon inflation through a single-handed operation interface, making the system self-sufficient without requiring division of labor between multiple physicians

Inventive Principle:
Principle #25Self-service

3Measurement precision

If the primary physician focuses on operating the insufflator, then accurate inflation pressure is achieved, but catheter positioning may be compromised

Engineering Contradiction:
Improveinflation pressureVSAvoidvessel damage risk
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

By merging the insufflator and syringe into one integrated device operable with one hand, the patent allows the primary physician to maintain simultaneous control over both inflation pressure and catheter positioning, preventing vessel damage from improper placement

Inventive Principle:
Principle #5Merging (Combining)
