Abstract

A method and apparatus is provided for aspiration of all patients, providing both a rigid suction hollow tube and a flexible suction hollow tube. The apparatus also include a ventilation adapter and a detachable tube for suctioning of liquid and particulate matter, such as meconium, and for intubation. Accordingly, oropharyngeal and nasopharyngeal suctioning of fluids and particulate matter is possible, as well as instillation of fluids and suctioning of the lower passageways, esophagus and stomach. The apparatus also includes a projecting appendage forming an oblique angle with the device, as an inlet port for delivery of oxygen or negative pressure and which can also function as a hook for conveniently hanging the device on a nearby edge.
