Solution Overview

Problem

The preparation of infusion sets is laborious, time-consuming, and physically demanding for medical staff, particularly in high-demand hospital settings, posing risks such as air bubbles and contamination, and exacerbating staff shortages and time pressures.

Innovation Solution

An infusion system with a pre-filled infusion set packaged in a sterile package, minimizing manual filling and venting, requiring only connection to an infusion container and a final check, reducing preparation time and human error.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual filling and venting of infusion sets is performed, then the infusion set can be prepared for use, but preparation time and physical effort increase significantly

Engineering Contradiction:
Improveease of infusion set preparationVSAvoidpreparation time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The infusion set is pre-filled with infusion fluid and pre-vented during the packaging process before sterile sealing. This preliminary action eliminates the need for manual filling and venting operations by medical staff, directly resolving the contradiction by maintaining ease of operation while dramatically reducing preparation time.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If manual filling and venting operations are performed frequently, then infusion sets can be prepared, but physical strain on medical staff increases

Engineering Contradiction:
Improvenumber of infusions preparedVSAvoidphysical effort required
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The manufacturing process performs filling and venting operations in advance during packaging, transferring the physical effort from medical staff to automated manufacturing equipment. This enables high productivity without imposing physical strain on operators who must repeatedly handle heavy infusion containers.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If rapid preparation of multiple infusion sets is required, then time pressure increases, but the risk of air bubbles and contamination increases

Engineering Contradiction:
Improvepreparation speedVSAvoidpatient safety
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The infusion sets are pre-filled and pre-vented under controlled manufacturing conditions, ensuring proper air removal and sterile sealing before delivery to the clinical setting. This allows rapid deployment of multiple infusion sets without compromising patient safety, as the critical safety-critical steps have already been performed correctly during manufacturing.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The pre-filled, pre-vented infusion sets are designed to be ready-for-use with minimal manual intervention required. The system essentially prepares itself during manufacturing, eliminating the need for time-consuming manual preparation steps that could introduce errors or contamination risks.

Inventive Principle:
Principle #25Self-service

4Productivity

If more infusion sets are prepared in advance, then availability improves, but the risk of human error increases

Engineering Contradiction:
Improveinfusion preparation throughputVSAvoiderror rate
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

Critical preparation steps including filling, venting, and sterile sealing are performed during automated manufacturing rather than manual preparation. This transfers the preparation process from human operators prone to error to automated systems with consistent, repeatable processes, enabling high-volume preparation without increasing error rates.

Inventive Principle:
Principle #10Preliminary action
