Device description

There are two NO2 filters in the LungFit PH; the main 12 hr NO2 filter (p/n 90008) that the user can change and the internal bagging 48 hr NO2 filter p/n 90009).The purpose of the NO2 filters is to remove NO2 from the NO gas flow and to collect any particulates that may be in the gas flow path. When the main 12 hr filter is inserted, this NO2 filter communicates with the LungFit device through an RFID wireless chip that is mounted on the filter. The RFID chip on the filter tracks and updates with the filter’s remaining usage time to prevent the filter from being accidently re-used after it has been consumed. The RFID also communicates wirelessly with the Gas Monitoring CPU, as described below. The NO2 filter includes two 1µm filters and two 5µm filters, with the NO2 filter material Sofnolime (soda lime) sandwiched between the particulate filters. Soda lime is a material that is commonly used in anesthesia CO2 absorbers. The duration of use for each main filter is pre-established as 12 hours. The RFID tag tracks filter usage so that the remaining time is updated continually every minute and displayed on the device user interface (i.e., as Time Remaining). The Gas Monitoring CPU detects whether a filter is installed and displays the Change Filter alarm to alert the user to change/insert a new user when no NO2 filter is present. The device also displays the Change Filter alarm when the NO2 filter has been consumed (no more minutes remaining).
