Abstract

A fluid sample dispenser comprises a microdosing device for outputting, during an activation state, a fluid sample at a fluid sample outlet to the environment, wherein the microdosing device is placeable adjacent to a person's nose so that a distance between the outlet of the microdosing device and a nostril of the person's nose is within a predefined range, and a microdosing driver unit for adjusting a dosing rate of the scent sample output at the scent sample outlet by selectively activating the microdosing device.

Description

technical field [0001] The present invention relates to a controllable fluid sample dispenser and use thereof to provide a fluid sample to a human nose at a predetermined and precise dosage rate. In particular, the present invention relates to a fluid sample dispenser for controllably dispensing or applying a scent, fragrance, aroma sample or medicine or medicament to a person using the controllable fluid sample dispenser of the present invention. Accordingly, the present invention generally relates to the field of precisely dispensing or applying any fluid sample, specimen or assay reagent to the respiratory system of a human / user. Furthermore, the present invention relates to a method for determining the minimum concentration of a fluid sample that can be detected by a person, and further to a method for determining the detection limit of a fluid sample of a fluid detection device. Background technique [0002] Known odor delivery systems are configured to provide a speci...
