Dialysis Pump Setting Selection From Target Renal Dose
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Setting adjustable values for blood treatment apparatuses, such as dialysis machines, is a demanding and error-prone task due to the interdependence of various treatment parameters, which can lead to inaccuracies and increased complexity for users.
Innovation Solution
A computer system with input and output interfaces, a calculation device, and a display is used to assist users in setting adjustable values by calculating and displaying a selection range of combinations for blood pump and dialysis liquid pump settings based on target values, allowing users to select the appropriate settings directly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually input adjustable values via screen or other interfaces, then the blood treatment apparatus can be operated, but the setting process becomes demanding and error-prone due to interrelated treatment parameters
Solution Approach 1:
The system performs preliminary calculations to determine a selection range of adjustable values that satisfy the target value before the user makes settings. The calculation device calculates the selection range based on the target value and displays it to the user, so the user only needs to select from pre-calculated valid options rather than manually determining correct parameter combinations.
Solution Approach 2:
The calculation device acts as an intermediary between the target value and the adjustable values. It receives the target value, calculates the corresponding selection range of valid adjustable values, and presents these options to the user, thereby mediating the complex relationship between treatment goals and parameter settings.
2Manufacturing precision
If users determine a series of interrelated adjustable values to achieve predetermined treatment goals, then the treatment targets can be met, but the setting activity becomes demanding and complex
Solution Approach 1:
The system performs preliminary calculations to determine a selection range of adjustable values that satisfy the target value before the user makes settings. The calculation device calculates the selection range based on the target value and displays it to the user, so the user only needs to select from pre-calculated valid options rather than manually determining correct parameter combinations.
Solution Approach 2:
The system transforms the complex multi-parameter setting problem into a simpler selection problem by changing the parameter representation from individual adjustable values to a selection range derived from the target value. This parameter transformation reduces the complexity of the setting process while maintaining precision.
3Ease of operation
If the calculation device displays a selection range of combinations, then the user can easily select appropriate settings, but additional calculation and processing time is required
Solution Approach 1:
The system calculates and displays a selection range that may include more options than the user will ultimately choose. Rather than calculating exactly one optimal setting, it provides a range of valid options that satisfy the target value, allowing the user to select from pre-calculated choices without requiring real-time calculation during the selection process.

AI summary
A computer system for setting adjustment values of a blood treatment apparatus includes a first input interface, a second input interface, an output interface, a display device, and a calculation device. The calculation device is programmed, after reading a target value for the renal dose via a blood treatment apparatus, to display to the user in a graphic via the display device, a selection range from several combinations, each of one adjustable value for the flow of the blood pump and one adjustable value for the flow of the dialysis liquid pump. Based on the displayed selection range, the user can select one of the displayed combinations via the second input interface. The calculation device is further programmed so that the adjustable value for the blood pump and the adjustable value for the dialysis liquid pump of the selected combination can be given via the output interface.
