Title:
APPARATUSES AND METHODS FOR GENERATING AND MEASURING ENVIRONMENTAL LEVELS OF ALLERGENS
Document Type and Number:
WIPO Patent Application WO/2016/083948
Kind Code:
A3
Abstract:
The present disclosure provides an apparatus comprising an air circulating device, an allergen source comprising an allergen, and a housing. The housing can be collapsible, portable, disposable and configurable. The present disclosure also provides a method comprising positioning an allergen source comprising an allergen in a chamber, distributing at least a portion of the allergen from the allergen source within the chamber, and collecting at least a portion of the distributed allergen. In an embodiment, the level of the shed allergen can be used to measure the effectiveness of various measures implemented to reduce airborne Fel d1 that is emitted from soiled cat litter. In another embodiment, the allergen can be introduced at a desired level in the chamber, and the resultant symptoms of a subject (e.g. a human) within the chamber can be identified and correlated with the amount of allergen.
