Open Spirometry Network

After a variety of tests, the Fleisch-type spirometer proved to be the best for our spirometer design. The rough prototype that we tested has been refined, and a new and improved Fleisch spirometer was built. See the new pictures below, and click here to see the design dimensions.

Design Updates

We revised our design from the Venturi design, and we now need to decide whether to build a Lilly or Fleisch type spirometer. Both are currently used in commercial models. We are examining the pros and cons of each design and hope to have a basic prototype of each built by the end of [...]

Last week we met with David Van Sickle and David Hubanks of ZMD America, Inc. – which has a Madison office – to discuss the possibility of utilizing one of ZMD’s signal conditioners in the spirometer circuitry. David H drew our attention to one in particular (the 31014), which costs only around $2.
There are numerous [...]

The BME students have been working hard for a little more than one month now and are making good progress. Last week, they began testing various differential pressure sensors in simple systems like the one you see here.
They’ve started preparing for their upcoming mid-semester presentation on the project which will take place Friday afternoon. I hope [...]

 
One of the most fun and challenging parts of this project is trying to build creative solutions to problems that are inefficiently solved today by commercial markets – in other words, solutions rooted in a different ethic that presume an abundance of funds.
In the case of the spirometer, nowhere is this more apparent than with the [...]
