Patient interface assemblies for use in ventilator systems to deliver medication to a patient
First Claim
1. A ventilator system comprising:
- a ventilator device having an inhalation port and exhalation port;
a patient conduit for delivering to and removing gas from the patient;
an exhalation conduit fluidly connected to the exhalation port and the patient conduit;
an inhalation conduit fluidly connected to the inhalation port and the patient conduit, the inhalation conduit at least in part defining a holding chamber; and
a device for generating aerosolized medication, the device being fluidly connected to the inhalation conduit so that the aerosolized medication is delivered to the patient as the patient inhales;
wherein at least a first inhalation conduit section of the inhalation conduit that is located between the device and the patient conduit has a variable length to position the device for generating aerosolized medication a predetermined distance from the patient conduit, the first inhalation section being defined by a body that is both extendable and contractable along a length of the body to permit a volume of the holding chamber to be varied and thereby provides a means for adjusting the strength of the dose of medication, wherein the first inhalation conduit section includes a plurality of markings each corresponding to a volume of the holding chamber based on the length of the first inhalation conduit section, the markings thus providing settings to assist in adjusting the strength of the medication that is generated and delivered to the patient from the device.

11. A ventilator system comprising:
-
a ventilator device having an inhalation port and exhalation port; a patient conduit for delivering to and removing gas from the patient; a heat moisture exchanger in fluid communication with the ventilator device; a first exhalation conduit fluidly connected to the exhalation port and the heat moisture exchanger; a first inhalation conduit fluidly connected to the inhalation port and the heat moisture exchanger; a second exhalation conduit fluidly connected to the patient conduit and the heat moisture exchanger; a second inhalation conduit fluidly connected to the patient conduit and the heat moisture exchanger; and a device for generating aerosolized medication, the device being fluidly connected between the second inhalation conduit and the heat moisture exchanger so that the aerosolized medication is delivered to the patient as the patient inhales; wherein at least the second inhalation conduit has a variable length due to the second inhalation conduit being having a body that is both extendable and contractable along the length thereof to permit positioning of the device for generating aerosolized medication a predetermined distance from the patient conduit and thereby permits a volume of the holding chamber to be varied and thereby provides a means for adjusting the strength of the dose of medication, wherein the second inhalation conduit section includes a plurality of markings each corresponding to a volume of the holding chamber based on the length of the second inhalation conduit section, the markings thus providing settings to assist in adjusting the strength of the medication that is generated and delivered to the patient from the device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A ventilator system comprising:
-
a ventilator device having an inhalation port and exhalation port; a patient conduit for delivering to and removing gas from the patient; an exhalation conduit fluidly connected to the exhalation port and the patient conduit; an inhalation conduit fluidly connected to the inhalation port and the patient conduit; a device for generating aerosolized medication, the device being fluidly connected to the inhalation conduit so that the aerosolized medication is delivered to the patient as the patient inhales;
wherein at least a first inhalation conduit section of the inhalation conduit that is located between the device and the patient conduit has a variable length due to the first inhalation conduit section being formed of a body that is both extendable and contractable along the length thereof to position the device for generating aerosolized medication a predetermined distance from the patient conduit, the variable length of the first inhalation conduit section permitting a volume of the holding chamber to be varied and thereby provides a means for adjusting the strength of the dose of medication, the inhalation conduit including a second inhalation conduit section located between the device and the ventilator device, wherein at least a first section of the exhalation conduit has a variable length;a humidifier unit in fluid communication with the inhalation conduit and the inhalation port for receiving compressed air from the ventilator device and then heating and adding moisture to the compressed air; a first heating wire that is incorporated into an inner wall of the second inhalation conduit section in a coiled manner such that a length of the second inhalation conduit section can be varied; and a second heating wire that is incorporated into an inner wall of the first section of the exhalation conduit in a coiled manner such that a length of the first section of the exhalation conduit can be varied.
