Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current injection systems face challenges in efficiently delivering contrast agents with high viscosity, requiring high pressure and leading to patient discomfort, and are not compatible with soft bags, which offer cost and storage benefits.
Innovation Solution
The injection system incorporates a bag holder that can mount on a bottle holder, allowing for the use of both rigid bottles and soft bags, with a heating device to maintain the contrast agent at body temperature, reducing viscosity and improving delivery efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high pressure is applied to inject contrast agent, then injection efficiency is improved, but patient comfort deteriorates
Solution Approach 1:
The patent applies thermal energy to heat the contrast agent, changing its temperature parameter from room temperature to body temperature (37°C). This parameter change reduces the viscosity of the contrast agent, allowing it to be injected at lower pressures while maintaining efficient flow rates, thereby improving patient comfort without sacrificing injection efficiency
2Productivity
If contrast agent is pre-warmed, then viscosity is reduced and injection efficiency is improved, but device complexity increases
Solution Approach 1:
The patent merges the heating function with the existing injection system by integrating a heating device into the supply station. The heating device is positioned within the chamber formed by the bottle holder and protective cover, combining thermal conditioning with the fluid delivery system. This integration allows pre-warming of the contrast agent without requiring separate dedicated equipment, thus improving injection efficiency while minimizing increases in device complexity
Solution Approach 2:
The heating device is designed to warm the contrast agent before injection occurs. By performing the heating action in advance during the supply phase, the system ensures that the contrast agent reaches optimal temperature and reduced viscosity before the actual injection process begins, thereby improving injection efficiency without adding complexity to the injection mechanism itself
3Ease of manufacture
If soft bags are used instead of rigid bottles, then cost and storage efficiency are improved, but compatibility with traditional injection systems deteriorates
Solution Approach 1:
The patent designs the supply station with a universal holder structure that can accommodate both rigid bottles and soft bags. The holder is configured to securely position various container types within the chamber, and the protective cover can be adjusted or removed to accommodate the different shapes and flexibility of bags versus bottles. This universal design enables the injection system to use cost-effective soft bags while maintaining compatibility with traditional injection mechanisms
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
This solution enables efficient and comfortable injection of contrast agents by reducing viscosity and allowing the use of cost-effective soft bags, while maintaining compatibility with traditional systems.
Implementation Method 1
the viscosity of most contrast agents may be reduced by increasing their temperature. Therefore, the contrast agent is generally pre-warmed before being injected
Implementation Method 2
the viscosity of the contrast agent may adversely affect its correct injection in the patient... the viscosity of most contrast agents may be reduced by increasing their temperature
Implementation Method 3
The bottle holder and the protective cover define a (closed) chamber, which may also provide for a thermal insulation of the bottle
