A1 Acoustic Rhinometer Clinical | A1-C

Description

An Acoustic Rhinometer produces a high intensity, very short duration sound pulse in the sound tube and this is applied to one side of the nose. Whenever this pulse meets a change in cross sectional area, a reflection is produced, which returns to the sound tube and is picked up by a microphone. The outgoing and returning signals are processed by a PC to provide a plot of cross sectional area, as a function of distance, into the nose. Numerical information such as the area at certain distances into the nose, and volumes between certain points in the nose, are calculated and presented, which highlight and quantify the points of obstruction.

Applications include:

• Surgical pre/post comparisons
• Nasal symmetry assessment
• Allergen challenge recording
• Sleep studies
• Quantifying changes due to Surgery, Decongestants or Medication

The A1 Clinical version provides a patient database, software calibration, colour selection facility for screen and printout, patient record screen editing, adjustable scale setting, calculation of the first two minimum areas, the distance at which minimas were found, the volume between any three distances, and user defined printout headings. A starter pack of consumables is also supplied.

Five pairs of medium and large anatomically conformed nosepieces, and fifteen sets of 8mm conical nosepieces are also supplied. Software is supplied on a USB flash drive.
