Advanced infection protection for patients & medical staff
NDD’s advanced lung function testing products were originally designed for effortless infection control. NDD products are small with easy-to-wipe surfaces. There are no fragile sensor parts to be cleaned, due to NDD’s advanced TrueFlow ultrasound technology. And testing elements in touch with patient breath are single-use and exchangeable.
Now, NDD’s new inline filter solutions add an extra level of safety. These solutions ensure dependable “double protection” from infection: the filter helps keep the ambient environment clean for technicians and other patients, and NDD’s unique Spirette and FlowTube design protects the flow sensor from cross-contamination.
NDD inline filter solution designs allow for lung function testing accuracy and infection control
NDD’s new inline filter solutions were designed (carefully and rigorously) to ensure test accuracy while still offering advanced protection from infection.
General guidelines state that if an “in-front” filter is used during lung tests, product tubing behind the filter still needs to be cleaned daily. This is not necessary with NDD lung function testing products, as all NDD test elements that come into contact with patient breath are exchanged – NDD Spirettes, adapters, and filters are all ‘single-patient use.’
Additionally, some filters show lower filtration efficiency at high flow rates (a common issue in spirometry tests). Lower efficiency leads to higher contamination for all tubing that sits behind or ‘downstream’ of the filter. This is not an issue with NDD lung function testing products, as the easy exchange of tubing avoids any risk of cross-contamination.
