Olfactory-action meter for precise quantification of olfactory dysfunctions and neurocognitive deficits

An apparatus (100) for quantitative assessment of olfactory dysfunctions and cognitive deficits, the apparatus comprising:

• one or more first filters (104-1) configured in the apparatus, the one or more first filters adapted to sterilize air received from an air pump (102);
• a second filter (106) coupled to the one or more first filters, the second filter adapted to filter odor molecules from the air;
• a manifold (108) coupled to the second filter (106) and adapted to split the sterilized air into a plurality of channels, wherein at least one channel of the plurality of channels carries the sterilized air to a first mass flow controller (MFC) (110) and adjacent channels carry sterilized air to one or more second mass flow controllers (MFCs) (112);
• a reservoir (114) comprising a plurality of containers (126), each container of the plurality of containers filled with an odorant different from adjacent containers, the sterilized air from each of the one or more second MFCs (112) is received by corresponding containers (126), wherein predetermined volume of odor vapour discharged from the reservoir (114) mixes with predetermined volume of sterilized air controlled by the first MFC (110), the sterilized air from the first MFC (110) is bifurcated into a plurality of channels corresponding to containers using solenoid valves (116);
• and
• a nozzle (118) coupled to the reservoir (114) and adapted to receive the odorized air from the reservoir (114) that is inhaled by a subject through an odor delivery unit (124), the odor delivery unit coupled to the nozzle, wherein based on degree of variation in volumetric concentration of the odorants, quantitative assessment of olfactory dysfunction in the subject is determined.
