Latest Patents

Stedman holds a patent for an "Inhalation Toxicology Chamber." This invention is a multi-level, animal inhalation toxicology research chamber system. It features an enclosed airtight chamber that defines a central enclosure with vertically extending inlet and outlet plenums at opposite ends. The design includes a plurality of vertically spaced, horizontally extending perforated shelves with underlying collection pans. These shelves support laboratory animal cages that are vertically spaced on multiple levels. Air is distributed from the inlet plenum to the outlet plenum through the animal cages in a horizontal direction. The collection pans prevent vertical fluid communication, allowing for the passage of animal waste into the collection pan. This design prevents animals from contacting their own waste and stops waste from falling on animals located beneath an upper cage.
