Solution Overview

Problem

Existing condition determination devices, such as those using NEWS or qSOFA, face accuracy issues when incomplete physiological information is available, as they cannot easily indicate if the calculated score is based on missing data, leading to lower accuracy.

Innovation Solution

A condition information generation device that acquires patient physiological information, determines if any information is missing, and generates missing information indicators, allowing for the generation of condition information and complementary data to address missing values, thereby improving accuracy and user understanding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If a score is calculated based on acquired physiological information even when some information is insufficient, then the device can provide condition information quickly, but the accuracy of the condition information decreases

Engineering Contradiction:

Improvetime to generate condition informationVSAvoidaccuracy of condition information

Core Design Contradiction:

Loss of timeVSMeasurement precision

Solution Approach 1:

The device segments the condition information into two parts: the calculated score based on available physiological information, and a separate indicator showing whether all necessary information was acquired. This segmentation allows the system to provide timely condition assessment while transparently indicating the completeness and reliability of the data used.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The device introduces an intermediary indicator (showing whether all necessary physiological information was acquired) that mediates between the calculated score and the user's understanding of its reliability. This intermediary element bridges the gap between partial data availability and accurate condition assessment by explicitly communicating data completeness status.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the device calculates a score using incomplete physiological information, then it can operate with available data, but the reliability of the condition determination decreases

Engineering Contradiction:

Improveability to operate with available dataVSAvoidreliability of condition determination

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The device implements feedback by providing an indicator that returns information about the completeness of acquired physiological information to the user. This feedback loop allows users to understand whether the condition determination is based on complete or partial data, enabling them to assess the reliability of the results and take appropriate follow-up actions.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The device performs preliminary assessment of data completeness before finalizing the condition information output. By checking whether all necessary physiological information has been acquired and displaying this status, the system prepares the user to interpret the condition score with appropriate confidence levels.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If the device does not indicate missing information, then the interface remains simple, but users cannot easily grasp the accuracy of the condition information

Engineering Contradiction:

Improvesimplicity of interfaceVSAvoidinformation about data completeness

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The device applies local quality by adding a specific indicator element that provides detailed information about data completeness at a particular location in the interface, while keeping the rest of the interface simple. This localized addition of information quality allows users to easily grasp accuracy details without complicating the overall interface design.

Inventive Principle:

Principle #3Local quality

AI summary

A condition information generation device includes an acquisition unit configured to acquire physiological information of a patient, a storage unit in which a determination method for determining a condition of the patient is stored, and a generation unit configured to generate condition information on the condition of the patient based on the acquired physiological information and the determination method. The generation unit determines whether there is missing physiological information in the acquired physiological information with respect to physiological information normally used when the determination method is executed, and generates missing information indicating that there is missing physiological information in a case where there is missing.
