Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing injection systems for contrast agents face challenges in maintaining the target temperature of high-viscosity contrast agents during medical imaging procedures, leading to inefficient injection and discomfort for patients due to heat loss and inadequate heating solutions.
Innovation Solution
The use of two thermal conditioning elements, a first heating element arranged around the connection port and a second heating element extending transversally, within the closed chamber of the supply station, to maintain the contrast agent at a consistent body temperature, improving heat retention and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a single heating device is used to warm the contrast agent, then the contrast agent temperature increases, but the heating efficiency is insufficient and power consumption is high
Solution Approach 1:
The heating device is divided into two separate heating elements: a first heating element arranged around the connection port and a second heating element extending transversally. This segmentation allows each element to heat different regions of the contrast agent independently, improving overall heating efficiency and reducing the total power required compared to a single heating device.
Solution Approach 2:
Each heating element is positioned to target specific local regions where heat loss occurs most significantly - one at the connection port and one extending transversally. This localized heating approach ensures that energy is applied precisely where needed, improving heating efficiency while minimizing overall power consumption.
2Stability of the object's composition
If heating elements are added to maintain contrast agent temperature, then temperature uniformity improves, but device complexity increases
Solution Approach 1:
The first and second heating elements are integrated into a unified heating device structure that works together to maintain temperature uniformity. By combining these elements in a coordinated arrangement, the system achieves improved temperature distribution without proportionally increasing overall device complexity.

AI summary
A solution for injecting one or more fluids into a patient is proposed. A corresponding injection system (200) comprises one or more supply stations (105a;105b) each one for supplying one of the fluids to be injected from a container (110a;110b); at least one of the supply stations (105a;105b) comprises housing means (115a, 120a;115b, 120b) defining a chamber for housing the container (110a;110b), the chamber having a connection port (132a;132b) for connecting the container (110a; 110b) to a delivery arrangement (135,145) for delivering the fluid to the patient, and a conditioning device (205a;205b) for thermally conditioning the fluid in the chamber, wherein the conditioning device (205a;205b) comprises a first conditioning element (210a;210b) arranged around the connection port (132a;132b) and a second conditioning element (215;215a;215b) extending transversally to the first conditioning element (210;210a;210b).
