?:definition
  • Equipment designed to clean hearing aids using vacuum. This equipment typically consists of a portable unit that provides partial vacuum pressure and includes a vacuum drying (i.e., desiccator) chamber where the hearing aid is housed, a vacuum hose with a probe that may be connected to several detachable tips at its distal end for external cleaning of the hearing aid components, controls to regulate the pressure inside the chamber, and filters. The units may also include a manometer to measure the pressure inside the vacuum chamber and/or a set of tools (e.g., brushes, picks) to facilitate the external cleaning procedure. Vacuum hearing aid cleaning units are used for periodic cleaning, preventive maintenance, and during repair of hearing aids and/or ear molds as an alternative to manual cleaning procedures.
