| description | Nikhil Gadiraju,* Nikhil Peterson,* Jessica Shah,* Annabelle Chu, Michael A Larbie II, Amy Bu, Ann Saterbak Pratt School of Engineering, Duke University, Durham, NC, USA*These authors contributed equally to this workCorrespondence: Ann Saterbak, Department of Biomedical Engineering, Duke University, 101 Science Drive, Campus Box 90281, Durham, NC, 27708-0281, USA, Tel +1 919 660 5899, Fax +1 919 684 4488, Email ann.saterbak@duke.eduPurpose: Long-term oxygen therapy involves utilizing stationary oxygen concentrators to allow patients with respiratory illnesses to attain sufficient blood oxygenation via supplemental oxygen. Disadvantages of these devices include their lack of remote adjustability and domiciliary accessibility. To adjust oxygen flow, patients typically walk across their homes – a physically taxing activity – to manually rotate the knob of the concentrator flowmeter. The purpose of this investigation was to develop a control system device that allows patients to remotely adjust the oxygen flow rates on their stationary oxygen concentrator.Methods: The engineering design process was used to develop the novel FLO2 device. The two-part system is composed of 1) a smartphone application and 2) an adjustable concentrator attachment unit that mechanically interfaces with the stationary oxygen concentrator flowmeter.Results: Product testing indicates that users successfully communicated to the concentrator attachment from a maximum distance of 41m in an open field, suggesting usability from anywhere inside a standard home. The calibration algorithm adjusted oxygen flow rates with an accuracy of ± 0.019 LPM and a precision of ± 0.042 LPM.Conclusion: Initial design testing suggests the device as a reliable and accurate method of wirelessly adjusting oxygen flow on a stationary oxygen concentrator, but further testing should be performed on different stationary oxygen concentrator models.Keywords: oxygen therapy, respiratory disease, flow meter, wireless adjustment, medical device |
