Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lack of control over the timing of consecutive biological samples for medical tests can lead to misdiagnosis and inappropriate treatment due to unreliable test results, particularly in cases like non-ST-segment elevation myocardial infarction (NSTEMI), where timely sampling is critical.
Innovation Solution
A system comprising a registration device and a processing system that determines patient identity and sample timing based on predetermined protocol rules for medical tests, ensuring that subsequent biological samples are taken in compliance with established timing requirements, thereby providing reliable medical test results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual timing control of biological samples is used, then operational flexibility is maintained, but measurement precision and reliability deteriorate due to lack of exact timing control
Solution Approach 1:
The patent introduces a processing system as an intermediary between the manual sample collection process and the timing requirements. This processing system receives timing parameters, stores protocol rules, and provides timing guidance to healthcare professionals, thereby achieving precise timing control without requiring complex automated sampling equipment at the point of care.
Solution Approach 2:
The system performs preliminary actions by pre-defining protocol rules with exact timing requirements for different medical tests. These timing parameters are stored in the processing system before sample collection occurs, allowing healthcare professionals to receive advance guidance on when to collect samples based on the specific medical test and patient condition.
2Reliability
If automated timing control is implemented, then sample timing precision improves, but device complexity increases
Solution Approach 1:
The processing system serves as an intermediary that manages the complexity of timing control. It stores protocol rules with precise timing requirements and provides guidance to healthcare professionals, thereby ensuring reliable test results without requiring complex automated control mechanisms at the sample collection point.
Solution Approach 2:
The system provides feedback to healthcare professionals regarding the timing of sample collection. By comparing the current time against stored protocol rules and providing real-time guidance, the system ensures that samples are collected at the correct times while keeping the interface simple and easy to use.
3Measurement precision
If exact sample timing is enforced, then diagnostic accuracy improves, but ease of operation deteriorates due to stricter protocol adherence requirements
Solution Approach 1:
The processing system performs self-service by automatically retrieving protocol rules, determining appropriate timing parameters, and providing guidance without requiring healthcare professionals to manually calculate or remember complex timing requirements. The system manages the complexity internally while presenting a simple interface to the user.
Solution Approach 2:
The processing system acts as an intermediary that translates complex protocol requirements into simple, actionable timing guidance for healthcare professionals. This intermediary function maintains diagnostic accuracy by enforcing exact timing while preserving ease of operation through user-friendly interfaces.
