Development of a Breath Sampler and proof of concept

Abstract

In the last few decades, there has been a pervading interest in non invasive technologies for diagnosis, monitoring as well as for treatment in the medical field. As part of this trend, breath analysis has emerged, and although very promising, there is a main issue this field’s development faces, the lack of reproducibility and reliability of protocols since there’s no standardization in the sampling process. This project aims to develop a Breath Sampler focused on achieving a protocolized sampling methodology that allows the collection of the fraction of exhaled air that has been in contact with the alveoli and therefore is rich in metabolites. To do so, different improvements of hardware and software are implemented on a first Breath Sampler prototype and a proof of concept is carried out to verify that itoperates as intended.
