Abstract:
1. A medical device for combination lung ventilation and mucus clearance of a patient, comprising: a pressure generation source that provides both positive pressure gas flow for lung ventilation and negative pressure suction for mucus clearance, wherein the pressure generation source comprises at least one outlet for the positive pressure gas flow and at least one inlet for the negative pressure suction; a ventilation portion for providing positive pressure gas flow to the patient via the nose comprising a nasal interface and a flow channel having a first end and a second end, wherein the first end of the flow channel is in fluid communication with the outlet of the pressure generation source and the second end of the flow channel is in fluid communication with the nasal interface, wherein the ventilation portion includes a pair of ventilation valves, one near the first end of the flow channel adjacent the outlet and the other near the second end of the flow channel adjacent the nasal interface; and a mucus clearance portion for providing negative pressure suction to the patient via the mouth comprising a mouth interface and a suction channel having a first end and a second end, wherein the first end of the suction channel is in fluid communication with the inlet of the pressure generation source and the second end of the suction channel is in fluid communication with the mouth interface, wherein the mucus clearance portion includes a pair of suction valves, one near the first end of the suction channel adjacent the inlet and the other near the second end of the suction channel adjacent the mouth interface; a control unit for operating the pair of ventilation valves and the pair of suction valves; wherein the mucus clearance portion is completely separated from the ventilation portion such that the medical device is capable of maintaining positive pressure lung ventilation via the nasal interface while the mouth interface of the mucus clearance portion of the device is removed from the patient; wherein the pair of ventilation valves are closed by the control unit during use of the mucus clearance portion to provide negative pressure suction to the patient; and wherein the pair of suction valves are closed by the control unit during use of the ventilation portion to provide positive pressure gas flow to the patient, wherein the mucus clearance portion includes a mucus collection receptacle in communication with the suction channel.
