Abstract
The invention consists of the following basic elements: a propeller (helix) 1, an optional photoemitter 3 and a photoreceiver 4. The propeller, of the cylindrical type, is partitioned off transversely at each one of its blades (four in the figure, although their number may be different) by means of opaque sheets 2 (located in the centre of the blades in the figure, although they may be located at another place). Said partitions interrupt the beam of light from the photoemitter, preventing it arriving at the photoreceiver. These basic elements are inserted into a module 5 whose inside is a parallelepiped which is open in its front and rear part to allow the circulation of air. The photoemitter and the photoreceiver are also installed in said module. The module is fitted to a mask 6 which covers the subject's nostrils and mouth. It applies to medicine, psychology and biology.
