Abstract

The present invention relates to a spirometer which is aimed at personal use for pulmonary function tests, i.e. aimed at usage by users who do not have medical training and experience. By means of the invention, a compact and ergonomic spirometer comprising two ultrasonic transceivers which are directed towards a volume within a tube forming an air way and which enable reading of the signals produced by each other to make measurements regarding the air flow within the tube has been developed. Signal losses are avoided by positioning the transceivers in a way that the transmission lines (iii) of the transceivers deviate from a measurement line (ii) towards the air entry corresponding to the mouth of the user. The spirometer may be able to make measurements for air flows in both inhalation and exhalation.
