A device designed for partial insertion into a patient's mouth (in between the lips) to facilitate access to the respiratory system. It is typically a small rigid or semi-rigid hollow device with a shape and structure that enables an appropriate gastight seal and prevents collapse. The device accepts or attaches to, either directly or through other tubes/adapters, diagnostic/therapeutic respiratory devices (e.g., ventilator, inhaler, incentive spirometer, aerosol equipment, breath analyser). Some types generate a whistling sound to guide effective inhalation [e.g., during use of a metered dose inhaler (MDI)]. This is a reusable device which may be intended for single- or multi-patient use.
