Solution Overview
Problem
In less developed countries, there is a lack of access to efficient and effective diagnostic services for conditions like sickle cell disease and malaria, leading to inconclusive or delayed diagnoses, which can impact morbidity and mortality.
Innovation Solution
A point-of-care diagnostic system comprising a reader and a cartridge that includes a control module for optimizing test parameters and a sonication module for sample preparation, capable of detecting hemozoin using magneto-optical detection (MOD) to accurately diagnose conditions like malaria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If large laboratories with advanced diagnostic services are established, then diagnostic accuracy and capability are improved, but cost and infrastructure requirements increase significantly
Solution Approach 1:
The patent extracts the essential diagnostic function from complex laboratory infrastructure by developing a portable point-of-care device that performs malaria species detection without requiring large laboratory facilities, advanced power grids, or highly trained clinicians
Solution Approach 2:
The patent employs disposable cartridges containing pre-loaded reagents and magnetic beads for sample processing, eliminating the need for expensive, maintainable laboratory equipment while ensuring consistent diagnostic accuracy through single-use, pre-calibrated components
2Measurement precision
If trained diagnostic personnel are deployed, then diagnostic quality is improved, but operational cost and staffing complexity increase
Solution Approach 1:
The patent implements self-service through automated sample processing where the cartridge automatically performs lysis, separation, and detection functions without requiring trained operators to perform complex manual procedures or interpret results
Solution Approach 2:
The patent replaces manual diagnostic procedures requiring trained personnel with an automated magneto-optical detection system that uses magnetic fields and optical sensors to automatically identify and quantify malaria parasites
3Device complexity
If traditional diagnostic methods are used in remote areas, then device simplicity is maintained, but diagnostic time and treatment delay increase
Solution Approach 1:
The patent applies preliminary action by pre-loading the disposable cartridges with lytic reagents and magnetic beads before deployment to remote areas, enabling immediate sample processing without requiring on-site preparation or complex setup procedures
Solution Approach 2:
The patent uses periodic action through rapid magneto-optical detection cycles that quickly alternate magnetic field application and optical measurement, achieving fast diagnostic results in minutes while maintaining device simplicity suitable for remote deployment

Data Source
AI summary
A diagnostic system that includes a cartridge and a reader. The cartridge can contain a patient sample, such as a blood sample. The cartridge is inserted into the reader and the patient sample is analyzed. The sample can be processed for data collection and analysis to provide interpretative results indicative of a disorder, condition, disease or infection of the patient. For example, the data collection and analysis can determine one or more hemozoin characteristics.
