This invention provides a multi-channel oropharyngeal ventilation device, relating to the field of ventilation device technology, including an installation mechanism. The installation mechanism includes an inner groove and a fixing rod. Two sets of inner grooves are symmetrically arranged at both ends of the rear side of the main body of the installation mechanism, and the inner grooves are connected to the fixing groove at the rear end of the main body. In use, a gastroscopy tube or gastrointestinal delivery tube can be inserted into the patient's
throat through the
insertion hole and the connecting hole for examination. After use, by rotating the rotating component, the
insertion hole can be connected to the unused connecting hole. This design reduces the
risk of infection of the connecting hole due to repeated use, solving the problem of imperfect
insertion channel structure in oropharyngeal ventilation devices. During use, because gastroscopy or gastric tube delivery is frequently required, the
ventilation tube is frequently exposed to air, and its interior is frequently rubbed against
medical equipment, increasing the risk of
contamination of the ventilation device.
