Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydration measurement devices struggle to accurately determine the hydration status of patients, particularly in medical settings, due to variations in body composition and measurement inaccuracies, and lack the ability to provide comprehensive hydration assessments across different body regions.
Innovation Solution
A method and system that utilizes a hydration measurement device, optionally wearable, to measure hydration parameters on a first body part, collects patient-specific data, and generates a personalized data set by combining measured and reference hydration values, allowing for accurate determination of hydration status across the entire body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a hydration measurement device measures hydration parameters on a single body part, then the device complexity is reduced, but the measurement precision and reliability for determining overall patient hydration status deteriorates
Solution Approach 1:
The system divides the body into multiple measurement regions (first body part and second body part) and performs separate hydration measurements on each. The results are then combined through algorithms to determine overall hydration status, thereby achieving comprehensive assessment without requiring a single complex device to measure the entire body at once.
Solution Approach 2:
A data set generating device acts as an intermediary between the simple hydration measurement device and the final hydration assessment. This intermediary processes measurements from multiple body parts, incorporates patient-specific data, and generates personalized hydration profiles that accurately reflect overall hydration status.
2Reliability
If reference hydration values are collected from multiple body parts, then the reliability of hydration assessment improves, but the loss of time and data collection complexity increases
Solution Approach 1:
Reference hydration values are pre-collected and stored in a data set before the actual measurement process. This preliminary data collection allows the system to quickly compare against established references without requiring time-consuming measurements during the assessment process, thereby maintaining high reliability while minimizing measurement time.
Solution Approach 2:
Instead of repeatedly measuring the same body part multiple times, the system creates a virtual copy of the hydration profile by measuring different body parts and combining their data. This approach provides comprehensive hydration assessment without requiring repeated measurements of the same region, reducing time loss.
3Measurement precision
If invasive procedures are used to determine hydration status, then the measurement precision improves, but the object-affected harmful factors and patient comfort deteriorates
Solution Approach 1:
The system replaces invasive mechanical measurement procedures with optical measurement methods. Optical sensors non-invasively measure hydration parameters through light transmission or reflection through body tissues, achieving comparable or superior measurement precision without causing harm, discomfort, or interference with ongoing medical treatments.
Solution Approach 2:
Optical measurement serves as an intermediary between the external environment and the body's hydration state. This non-invasive intermediary method provides accurate hydration data without requiring direct physical intrusion into the body, thereby eliminating harmful factors associated with invasive procedures.

AI summary
The present disclosure relates to a method for generating at least one data set to be used for a hydration measurement device when measuring a hydration state of the patient. The method encompasses the step of providing a data set generating device, comprising at least one algorithm, or data, for generating a data set based on a measured hydration value of the patient on a first body part and a determined reference hydration value from a reference hydration data source selected with regard to collected further patient-specific data, the data set being usable for determining a reliable hydration value of a second body part of the patient or the overall hydration value when measuring with the hydration measurement device on the first body part of the patient. Storing the data set in a data set storage is also encompassed by the method.
