Abstract
A patient's airway adapter is fitted into a patient's airway, which is a combined breathing air supply and exhaust gas fluid flow passageway. The housing of this patient's airway adapter connects directly to a standard tapered tracheostomy or endotracheal tube connection or standard tapered portions of other fittings, and in turn provides a standard tapered connection to a patient's airway. The main air and gas stream, respectively, going to and from a patient, continues to flow directly through the patient's airway adapter. Samples of the patient's gas are withdrawn through a smaller diameter sampling exhaust port in the housing. The sampled patient's gas, immediately upon leaving the main air and gas stream, passes from the interior of a hollow cylindrical hydrophobic liquid baffle, through the baffle, and then into the sampling cannula enroute to a monitor. This hydrophobic baffle is held in a sealed position within the surrounding housing. Any mucus, sputum, and/or condensed water is kept from entering the smaller diameter sampling exhaust port, and therefore from entering the sampling cannula, as it collects on the inside of a cylindrical hydrophobic liquid baffle. The hydrophobic baffle material is a hydrophobic, hollow cylindrical baffle, having an unobstructed internal diameter in all embodiments.
