Abstract: The present disclosure includes methods, apparatuses, and systems for aspirating the airway of a patient. The apparatus includes a main body having a pump and a storage cannister housing coupled to the main body and containing a storage container that is at least partially collapsible. In some configurations, the main body can include a pressure sensor, a controller in communication with the pressure sensor, and having a processor, a memory, and a power source in communication with the controller. The storage cannister housing can include a first end coupled to the main body, and a second end having a weighted portion and configured to be coupled to the first end to permit free rotation, such that the second end gravitationally rotates.

Abstract: High molecular weight solid epoxy or phenoxy resins are dissolved in a blend of an alcohol solvent and an aprotic solvent. The resulting solution is spray-dried in a closed-cycle spray drier to form a powdered epoxy or phenoxy resin.
