Condition Information Generation Device Using Preliminary Action
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing condition information generation methods, such as NEWS and qSOFA, often result in discrepancies when calculating a subject's condition due to differences in timing between initial and secondary assessments by medical workers, leading to potential delays in accurate condition discrimination.
Innovation Solution
A condition information generation device and method that acquires physiological information and generates condition information based on a target time set arbitrarily earlier than the generation time, allowing for accurate condition assessment even when discontinuous measurement parameters are not available at the initial time, by using continuous and discontinuous measurement parameters from nearby times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If condition information is generated based on physiological information acquired at the current time, then the information is available immediately, but it does not accurately reflect the subject's condition at an earlier time when deterioration was first suspected
Solution Approach 1:
The system performs preliminary acquisition and storage of physiological information at earlier time points, enabling retrospective analysis. When a target time is specified, the system can retrieve pre-acquired data from that time point without waiting for current measurements, thus providing timely and accurate condition assessment at the historically relevant moment.
2Measurement precision
If physiological information is acquired continuously at all times, then accurate condition information can be generated at any target time, but the system complexity and data storage requirements increase
Solution Approach 1:
The system preliminarily acquires and stores essential physiological information (such as discontinuous measurement parameters) at predetermined time intervals. This preliminary data collection enables the system to generate condition information at arbitrary target times without requiring continuous real-time acquisition, thus balancing data availability with system simplicity.
3Ease of operation
If condition information is generated only when currently available, then the process is simple, but it cannot provide condition assessment at historical time points when medical workers first noticed deterioration
Solution Approach 1:
The system preliminarily stores physiological information at various time points, enabling users to request condition information at any historical target time. This maintains operational simplicity while preventing loss of historical condition data, as the system retrieves pre-stored information rather than requiring complex real-time reconstruction.
Solution Approach 2:
The system introduces a time specification mechanism as an intermediary between the user and the condition information generation process. By allowing users to specify a target time, the system mediates between the simplicity of current-time assessment and the need for historical condition data, enabling precise temporal control over information retrieval.

AI summary
A condition information generation device includes: an acquisition unit configured to acquire physiological information of a subject; and a generator configured to generate condition information of the subject based on the physiological information. The generator is configured to generate the condition information based on the physiological information acquired at a target time that is set arbitrarily, the target time being a time that is earlier than a time when the condition information generation device generates the condition information.
