eSpiro

A mobile spirometer that provides clinical level readings of lung health and function

 

Aim

Vigilant Health creates superior health outcomes by marrying smart device technology with data capture, data analysis, and Artificial Intelligence, to optimize chronic disease management. We've partnered with Virgilant to manage and oversee production of their full range of digital health products. Their first product to be released onto the market is a mobile spirometer device. 

It has been developed to be smaller than average spirometers and sends data to the Virgilant app and the cloud. The idea being that with more regular lung function readings and Ai learning, Virgilant can achieve better patient outcomes and better patient monitoring for clinicians.

Approach

Reducing size and costs:

Not necessarily two outcomes that come hand in hand! The eSpiro product is designed for use at home and therefore was designed to achieve the required functional outputs whilst keeping costs low for the end user. We were able to cost down for our client by choosing and applying the most economic production assembly techniques, for example we achieved this by using ultrasonic welding for the housing adhesive, and we have been very pleased with the results. 

To keep the end product as user friendly as possible, Virgilant involved our engineering team from the very beginning - at the Industrial Design stage. Our team was able to advise on a variety of factors at this point, such as charging port placement and button position, and avoided obstacles and re-designs when we reached out to manufacturing facilities. 

Keeping the product dimensions to a minimum for user pocketability was a vital outcome for this product, and therefore PCB size became a key challenge for our engineering team. Our engineers handled the PCB layout and verification, meeting regulatory requirements, carrying out testing and adhering to size limitations.
