Solution Overview

Problem

Existing blood purification treatment systems lack the ability to accurately assess whether treatment conditions should be changed based on patient data collected on non-treatment days, leading to potentially inappropriate judgments.

Innovation Solution

A blood-purification-treatment support system that includes a storage device for patient-specific data on multiple days, including no-treatment days, an estimating device to compare and estimate pre-treatment patient states, and a judging device to determine if treatment conditions should be altered, specifically considering lifestyle data and vital parameters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If patient data are only acquired and stored on treatment days, then the storage system is simple, but the accuracy of treatment condition judgment deteriorates due to lack of daily patient state information

Engineering Contradiction:
Improveaccuracy of treatment condition judgmentVSAvoiddata collection system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system collects patient data on no-treatment days in advance before the actual treatment day. By gathering lifestyle data, vital parameters, and exercise information beforehand and storing them in the storage device, the system prepares comprehensive data for future treatment judgment, ensuring accurate assessment of treatment condition changes without requiring complex real-time monitoring during treatment days

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The storage device acts as an intermediary between data collection on no-treatment days and treatment judgment on treatment days. It stores patient-specific data including lifestyle information and vital parameters, bridging the gap between daily patient state monitoring and periodic treatment decision-making, thereby enabling accurate judgment without continuous system complexity

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If treatment conditions are judged based on data from several days ago, then the judgment process is simple, but the reliability of treatment decisions deteriorates due to significant patient data changes

Engineering Contradiction:
Improvereliability of treatment decisionsVSAvoiddata freshness delay
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system continuously collects patient data on no-treatment days without interruption, maintaining an ongoing record of patient state through lifestyle data, vital parameters, and exercise information. This continuous data accumulation ensures that when treatment judgment is made, the most current and relevant patient information is available, eliminating gaps and ensuring reliable treatment decisions

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

Patient data is collected and stored in advance on no-treatment days before treatment days occur. This preliminary data gathering ensures that when treatment decisions need to be made, current and accurate patient information is already available in the storage device, eliminating delays and ensuring reliable treatment judgments

Inventive Principle:
Principle #10Preliminary action

AI summary

To provide a blood-purification-treatment support system capable of making an accurate judgement of whether or not any treatment conditions for blood purification treatment should be changed. The blood-purification-treatment support system is capable of supporting blood purification treatment. The system includes a storage device 1 that stores patient-specific patient data that are acquired on a plurality of days including at least no-treatment days on which blood purification treatment is not conducted, an estimating device 2 that compares the patient data for the plurality of days stored in the storage device 1 with one another and estimates a pre-treatment patient state regarding blood purification treatment, and a judging device 3 that judges from the pre-treatment patient state estimated by the estimating device 2 whether or not any treatment conditions for blood purification treatment should be changed.
