Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If electrical signal is unilaterally transmitted from dialysate supplying device to dialysis monitoring devices, then operation control is simplified, but accurate determination of actual condition of blood purification mechanisms becomes difficult
Solution Approach 1:
The patent implements bidirectional communication where dialysis monitoring devices transmit operation information back to the dialysate supplying device. This feedback mechanism enables the supplying device to accurately determine the actual condition of blood purification mechanisms while maintaining simplified control operations through automatic signal processing.
2Measurement precision
If multiple individual sensors are installed in each dialysis monitoring device to monitor temperature, pressure, concentration, and flow rate, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent consolidates multiple sensing functions (temperature, pressure, concentration, flow rate monitoring) into the central dialysate supplying device. By merging these monitoring capabilities at one location and using bidirectional communication to receive operation information from multiple dialysis monitoring devices, the system achieves comprehensive parameter monitoring without installing individual sensors in each monitoring device, thereby reducing overall system complexity.
3Productivity
If dialysate is distributed from a central supplying device to multiple dialysis monitoring devices, then productivity is improved, but accurate determination of individual mechanism conditions becomes difficult
Solution Approach 1:
The patent establishes bidirectional communication channels between the central dialysate supplying device and each dialysis monitoring device. Each monitoring device transmits its specific operation information (temperature, pressure, concentration, flow rate) back to the supplying device, enabling the central system to maintain efficient dialysate distribution while accurately tracking the individual condition of each blood purification mechanism.

AI summary
A blood purification system includes a plurality of monitoring devices (1) each attached to a dialyzer (5) to perform a blood purification treatment on a patient. A dialysate supplying device (2) supplies a dialysate to each of the monitoring devices (1). The plurality of monitoring devices (1) and the dialysate supplying device (2) are connected to each other by a LAN cable α. Thus, predetermined individual information relating to the plurality of monitoring devices (1) is transmitted from each of the monitoring devices (1) to the dialysate supplying device (2).
