Solution Overview
Problem
Current methods for detecting parasitic infections in dogs are slow, cumbersome, and often fail to detect asymptomatic or subtly symptomatic infections, necessitating a rapid and efficient diagnostic solution.
Innovation Solution
The use of Raman spectroscopy for point-of-care detection of parasitic infections in canine samples, employing multi-omic, multiplex analysis with portable, automated Raman spectrometers that require minimal sample preparation and can identify parasites in small sample sizes, utilizing machine learning algorithms for accurate genus, species, and strain identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional parasitic detection methods are used, then detection accuracy may be adequate, but the detection process is slow and cumbersome
Solution Approach 1:
The patent replaces traditional mechanical and chemical detection methods (microscopy, centrifugation, chemical reagents) with Raman spectroscopy, an optical-based detection system. This substitution enables rapid, automated detection without the cumbersome sample preparation and manual analysis required by conventional methods, directly resolving the contradiction between detection speed and method complexity.
Solution Approach 2:
The Raman spectroscopy system performs self-diagnosis by automatically analyzing the spectral signatures of parasites in fecal samples. The system requires minimal human intervention, as the spectral data is automatically processed and interpreted to identify parasitic infections, eliminating the need for skilled technicians to perform manual microscopy or complex sample preparation procedures.
2Productivity
If traditional detection methods are used, then comprehensive analysis is possible, but the process requires time-consuming reagents and complicated sample preparation
Solution Approach 1:
The patent extracts only the essential diagnostic information from the fecal sample through Raman spectroscopy, bypassing the need for time-consuming sample preparation steps such as centrifugation, staining, and mounting required by traditional methods. The spectral analysis directly identifies parasitic components without requiring physical separation or chemical treatment of the sample.
Solution Approach 2:
The Raman spectroscopy system serves multiple diagnostic functions simultaneously - it can detect various types of parasites, analyze sample composition, and provide identification all through a single measurement process. This multi-functionality eliminates the need for multiple separate tests and complex sample preparation protocols required by traditional detection methods.
3Ease of operation
If traditional detection methods are used, then detailed parasite identification is possible, but the methods are not suitable for point of care testing
Solution Approach 1:
The patent replaces laboratory-based mechanical detection systems with a portable Raman spectroscopy device that can be operated at the point of care. The optical-based system requires minimal sample preparation and provides rapid results without needing specialized laboratory infrastructure, making it suitable for veterinary clinics and field settings while maintaining detailed parasite identification capability.
Solution Approach 2:
The system performs preliminary spectral analysis directly at the point of care, capturing the diagnostic information in real-time without requiring subsequent laboratory processing. The Raman spectrum is immediately acquired and analyzed, providing rapid detection results that eliminate the time delay between sample collection and diagnosis inherent in traditional methods.
