Abstract

A system for detecting a disease agent in a sample derived from a patient biofluid may comprise a receiver coupled to a communication network and a controller coupled to the receiver. The controller may comprise a processor and a memory. The controller may be configured to generate an infrared spectrum of the sample. The sample spectrum may comprise one or more sample spectral components, the sample spectral components comprising a sample wavenumber and a sample absorbance value. A set of reference spectral models may comprise one or more reference spectral components. The reference spectral components may comprise a reference wavenumber and a reference absorbance value. The reference spectral components may comprise one or more pathogen characteristics associated with sepsis. The one or more sample spectral components may be classified as pathogenic using the reference spectral models. Pathogen data may be generated using the classified sample spectral components.

[0002] This application claims priority to Australian Provisional Patent Application No. 2016903287, entitled Spectroscopic Method and Device for Diagnosis of Pathogens causing Sepsis, filed 19 August 2016 rights, the contents of said Australian Provisional Patent Application are hereby incorporated by reference in their entirety. Background technique

[0003] sepsis

[0004] Sepsis is caused by a patient's immune response triggered by infection with a pathogen. The infection is most often bacterial, but can also be of fungal, viral or parasitic origin. Sepsis can be life-threatening when a patient's response to infection damages his own tissues and organs. Common signs and symptoms include fever, increased heart rate, increased respiratory rate, and confusion. But in the very young, the elderly, and people with weakened immune systems, there may be no specific symptoms of infection and the temperature may be low or normal ...
