Aspirators for surgical treatment of injuries nose and pharynx

摘要

Aspirator for surgical treatment of nasal injury and hypopharynx. It can be used for short operations in the nasal cavity and the pharynx under intravenous anesthesia without tracheal intubation. This technical solution is aimed at reducing post-operative complications in short operations in the nasal cavity and pharynx under intravenous anesthesia without tracheal intubation.; The novelty of the claimed aspirator is the presence of three catheters, which suction channels are connected to a three-channel connector for connecting to a vacuum device. Wherein each of the catheters is equipped with a perforation in the form of different-sized openings, decreasing in the proximal direction. To reduce mucosa traumatization best catheters are made of thermoplastic material, the density of which decreases at body temperature.; New technical result which may be achieved by the invention consists in the simultaneous emptying of both halves of the nasal cavity and the hypopharynx.
