With the SpiroNose from Breathomix, VOCs (volatile organic components) are measured in the exhaled air to diagnose lung diseases such as asthma, COPD, lung cancer, and other respiratory conditions. The breath sensor values are analyzed and corrected for the ambient air to create a breath profile for each patient. These breath profiles are compared with the breath profiles in the Breathbase. Evalan was asked to develop the sensor system and a secure data gateway and improve the design of the SpiroNose.
Breath analysis

The problem

Breathomix needed an IoT expert who could improve the SpiroNose and prepare it for large-scale rollout. In collaboration with Breathomix, Evalan developed a production version of the system. Evalan was responsible for all physical parts of the SpiroNose: the sensor system and a secure data gateway.

Goal: Standard medical measurement

The first series of SpiroNoses have been produced and delivered to various hospitals that will conduct research with the devices. Ultimately, the goal is for SpiroNose to become a standard medical measurement. Not in the hospital but at the doctor’s practice.
