Suction device

Abstract

There is provided a device comprising a funnel connected to a suction tube connectable to a suction device, the funnel comprising a reversibly inflatable portion. The device is preferably a nasopharangeal device suitable for insertion through a mouth of a patient, the funnel being formed so as to be sealably locatable in or around the nasopharangeal opening of the patient. There are further provided methods for protecting an airway of a patient from nasal-derived liquid and/or applying medicament and/or packing to a nasopharynx, oropharynx or nasal cavity of a patient using the inventive device. The device provides a system in which misting of endoscopic lenses is reduced or prevented. Embodiments of the device allow for the strength of applied suction to be controlled.
