Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current liquid injectors for imaging diagnostic apparatuses require complex operator input for determining the rate and amount of contrast medium to be injected, which can lead to errors due to the need for numerical data entry and consideration of various conditions, including body region and contrast medium type.
Innovation Solution
A liquid injector with a condition storage means, image storage means, section display means, region displaying means, operation reading means, and injection control means, allowing operators to select schematic images of body sections and regions, thereby automatically controlling the injection of contrast medium under optimal conditions without requiring complex numerical data entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator manually determines and enters numerical data for injection rate and total amount, then the injection can be performed with flexibility, but the operation becomes complex and error-prone
Solution Approach 1:
The system pre-stores optimal injection conditions (injection rate, total amount) for each body region and contrast medium type in a storage unit. When the operator selects a body region and contrast medium type, the corresponding injection conditions are automatically retrieved and set, eliminating the need for manual calculation and entry of numerical data, thus simplifying operation while ensuring reliable, error-free parameter setting
Solution Approach 2:
The liquid injector automatically retrieves and sets injection conditions based on the selected body region and contrast medium type without requiring manual input. The system serves itself by automatically configuring the optimal injection parameters, reducing operator burden and preventing erroneous manual entry while maintaining operational flexibility
2Productivity
If the operator enters numerical data for injection rate and total amount, then the injection can be customized, but the data entry process becomes complex and time-consuming
Solution Approach 1:
Optimal injection conditions are pre-calculated and stored for each body region and contrast medium type combination. The system automatically retrieves these pre-prepared conditions when the operator makes selections, eliminating the time-consuming manual data entry process while maintaining customized injection capabilities for different clinical scenarios
Solution Approach 2:
The system uses pre-stored templates of optimal injection conditions for each body region and contrast medium type. Instead of requiring the operator to create parameters from scratch, the system copies and applies the appropriate pre-established parameter set, dramatically reducing the time required for setup while ensuring optimal injection parameters are used
3Adaptability or versatility
If multiple types of contrast mediums with different concentrations are available, then the injection can be optimized for different regions, but the complexity of determining and entering appropriate parameters increases
Solution Approach 1:
The system pre-stores optimal injection conditions specifically tailored for each combination of body region and contrast medium type (including different concentrations). When the operator selects a body region and contrast medium type, the system automatically retrieves the corresponding pre-configured parameters, enabling adaptable optimization for different clinical scenarios without increasing operational complexity
Solution Approach 2:
The liquid injector is designed to handle multiple types of contrast mediums with different concentrations by providing a unified selection interface. The system universally manages different contrast medium types through a single operational workflow where the operator simply selects the contrast medium type and body region, and the system automatically applies the appropriate parameters, thus providing adaptability without increasing device complexity
Data Source
AI summary
A liquid injector stores data of operating conditions of a liquid injection mechanism for regions to be imaged, and also stores data of schematic images of a plurality of body sections and schematic images of regions to be imaged in association with each other. The liquid injector displays the schematic images in the shape of a human body. When one of the schematic images of the corresponding regions is selected, the liquid injector reads the data of corresponding operating conditions, and controls operation of the liquid injection mechanism according to the read operating conditions. When the operator manually selects one of the schematic images of the body sections and then manually selects one of the schematic images of the corresponding regions, the liquid injector automatically injects a contrast medium into the subject under operating conditions corresponding to the selected region to be imaged.
