Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional infusion planning methods are used, then the infusion process is simple and quick to plan, but the precision in determining the amount of medical liquid delivered to target versus non-target regions is insufficient
Solution Approach 1:
The system performs preliminary simulation of medical liquid distribution before the actual infusion procedure. Planning scan data is acquired and processed in advance to create a virtual model that predicts liquid distribution patterns, allowing optimization of infusion parameters before clinical application.
Solution Approach 2:
The system creates a virtual copy or simulation model of the patient's anatomy using planning scan data. This digital twin allows for testing and optimization of infusion parameters without affecting the actual patient, enabling precise prediction of medical liquid distribution patterns.
2Reliability
If infusion parameters are optimized for maximum target tissue delivery, then treatment efficacy is improved, but the amount of medical liquid introduced into non-target regions may increase
Solution Approach 1:
The system determines different infusion parameters for different spatial regions. By analyzing the virtual model, it identifies optimal flow rates, pressures, and durations that maximize delivery to target tissue while minimizing infiltration into non-target regions, applying localized quality control to different anatomical areas.
Solution Approach 2:
The simulation provides feedback on predicted medical liquid distribution patterns before actual infusion. This allows adjustment of infusion parameters based on predicted outcomes, optimizing the balance between target tissue delivery and non-target tissue protection.

AI summary
A method for planning an infusion of a medical liquid by an infusion apparatus comprising an infusion device, wherein the method comprises the steps of: acquiring planning scan data which represent a medical image of at least a body region (3) of a patient and are obtained by a planning scan before the infusion device is positioned; determining a planned device position from the planning scan data; acquiring verification scan data which represent a medical image of the region of the patient after the infusion device has been positioned; determining a source volume of the liquid from the verification scan data; and determining infusion parameters from the verification scan data and the source volume.
