Blood Purification Unit Calibration Data Sharing for Faster Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The setup time for separable-type blood purification devices is prolonged due to the need for recalibration of sensors and actuators when units are replaced.
Innovation Solution
A blood purification device comprising separate units with a storage unit to store calibration data, allowing data sharing and synchronization between units upon connection, thereby eliminating the need for recalibration during setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the blood purification device is composed of separate replaceable units, then ease of maintenance is improved, but setup time increases due to recalibration requirements
Solution Approach 1:
The patent uses data copying to transfer calibration data from a storage unit to a control unit when units are connected. This allows the control unit to acquire previously calibrated data without performing recalibration, thereby maintaining ease of maintenance through unit replacement while eliminating setup time loss.
Solution Approach 2:
The patent performs calibration in advance and stores the calibration data in a storage unit before unit replacement. When units are connected, this pre-stored data is automatically transferred to the control unit, eliminating the need for recalibration and reducing setup time while maintaining the ability to replace units for maintenance.
2Loss of time
If calibration data is stored and shared between units, then setup time is reduced, but device complexity increases
Solution Approach 1:
The patent segments the data management function by separating the storage unit (for calibration data) from the control unit (for data processing and unit coordination). This segmentation reduces device complexity by distributing functions across separate components while enabling calibration data sharing to reduce setup time.
Solution Approach 2:
The patent introduces a storage unit as an intermediary component that holds calibration data and enables transfer between units. This intermediary simplifies the data sharing mechanism compared to direct unit-to-unit communication, reducing overall system complexity while achieving rapid setup through data transfer.

AI summary
This blood purification device 1 is configured by being divided into a plurality of units 3 and 4. At least one unit 3 of the plurality of units 3 and 4 is configured so as to have a storage part 7 for storing calibration data 91 of the unit 3, and when the unit 3 is connected to the other unit 4, the calibration data 91 can be shared with the other unit 4.
