Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing field-deployable methods for diagnosing large vessel occlusions (LVOs) are either expensive, under-utilized, or operator-dependent, leading to delays and inefficiencies in providing appropriate medical intervention.
Innovation Solution
A portable, head-mounted diagnostic tool using near-infrared energy and transducer arrays to perform an area scan of the brain, autonomously detecting and deciphering cranial blood vessel blockage patterns, providing a binary signal on the presence of LVOs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If MRI or CT imaging is used to identify LVOs, then diagnostic accuracy is improved, but device portability and field deployability deteriorate
Solution Approach 1:
The patent replaces heavy mechanical imaging systems (MRI, CT) with a portable transcranial Doppler ultrasound system that uses acoustic waves instead of mechanical scanners to detect LVOs, achieving field deployability while maintaining diagnostic capability
Solution Approach 2:
The invention extracts the essential diagnostic function from complex imaging systems by using only the necessary ultrasound transducers and signal processing components, removing unnecessary bulk while preserving LVO detection capability
2Weight of moving object
If field-deployable ultrasound tools are used, then device portability is improved, but operator dependence and diagnostic reliability worsen
Solution Approach 1:
The system performs self-diagnosis by automatically analyzing ultrasound signals and comparing them against stored LVO patterns, eliminating the need for operator interpretation and reducing diagnostic variability
Solution Approach 2:
The system incorporates real-time feedback mechanisms where detected signal patterns are immediately compared with reference LVO patterns, providing automated confirmation or rejection of LVO presence without operator intervention
3Measurement precision
If comprehensive imaging is performed, then diagnostic completeness is improved, but time to diagnosis and intervention deteriorates
Solution Approach 1:
The system extracts only the critical diagnostic information needed for LVO detection from the ultrasound signals, ignoring extraneous data and focusing solely on flow reversal patterns, thereby reducing scan time while maintaining diagnostic accuracy
Solution Approach 2:
The patent uses a focused, targeted ultrasound approach that scans only the necessary cerebral vessels for LVO detection rather than performing comprehensive whole-brain imaging, achieving rapid diagnosis with sufficient diagnostic coverage

AI summary
Apparatus and methods for diagnosing conditions consistent with the presence of cranial blood vessel blockage and large vessel occlusions (LVO's) using the framework of a small head-harness that is transportable, field-expedient, and durable, A single pulse set using ultrasonic or near- infrared energy is broadcast into a patient's brain allowing the apparatus to perform an area scan of the brain and detect and decipher cranial blood vessel blockage and LVO signal patterns. The interpretation of the pattern lies within the internal programming which produces a binary signal as to whether an LVO is suspected or not.
