Sutter Medizintechnik GmbH
Sutter has developed the 4-phase rhinomanometer (4PR, 4RHINO), which was declared a standard in functional diagnostics in Nov. 2016. Sutter carries out optical examinations in an in-vivo nasal model and in-vitro analyses using 4PR to validate the numerical methods. In addition, the influence and the physical properties of the nasal flap, which can produce an airway collapse during accelerated ow, are investigated by means of elastography methods.
