Abstract
Systems and methods are disclosed for delivering medication to a patient. One such system has an aerosol generator for aerosolizing medication. The generator is located outside the airway of a patient. A chamber is provided for receiving aerosolized medication from the generator. The system has a carrier gas supply tube for delivering carrier gas to the chamber, and an aerosol delivery tube for receiving the aerosolized medication and the carrier gas from the chamber. The aerosol delivery tube delivers the aerosolized medication to the patient. A distal end of the aerosol delivery tube is positioned inside the airway of the patient in order to discharge the aerosolized medication within the patient's airway.
Claims28
A system for delivering medication to a spontaneously breathing, non-intubated patient, comprising:
- an aerosol generator for aerosolizing medication, the aerosol generator being located outside the patient;
- a chamber for receiving aerosolized medication from the aerosol generator;
- a carrier gas supply tube for delivering carrier gas to the chamber;
- an aerosol delivery tube in communication with the chamber for receiving the aerosolized medication and the carrier gas from the chamber, the aerosol delivery tube having a distal end for delivering the aerosolized medication to the patient;
- and
- a patient interface through which the aerosol delivery tube passes, and the patient interface securing the aerosol delivery tube so that the distal end of the delivery tube is positioned at or slightly beyond a distal end of the patient interface so as to prevent contact with oral tissues of the patient, and when used with a patient the distal end of the aerosol delivery tube is positioned in an oropharyngeal cavity of the patient in order to discharge the aerosolized medication within the patient's oropharyngeal cavity.
A method of delivering medication to a spontaneously breathing, non-intubated patient, comprising:
- providing a patient interface through which an aerosol delivery tube passes, which secures a distal end of the delivery tube at or slightly beyond a distal end of the patient interface so as to prevent contact with oral tissues of the patient;
- positioning the patient interface so that the distal end of the aerosol delivery tube is positioned in the patient's oropharyngeal cavity;
- generating an aerosol from a medication to provide an aerosolized medication, wherein generating the aerosol occurs outside the patient;
- providing a flow of carrier gas;
- using the carrier gas, conveying the aerosolized medication via the aerosol delivery tube to the patient's oropharyngeal cavity;
- and
- discharging the aerosolized medication from the distal end of the aerosol delivery tube to the patient's oropharyngeal cavity.
