Abstract: A gas venturi connector includes a venturi body having an open first end and an opposing second end that includes a gas port for connection to a supplemental gas source. The venturi body includes a first air entrainment window and a second air entrainment window spaced from the first air entrainment window. Each of the first entrainment window and the second air entrainment window has an L-shape. The connector also has a movable shutter that rotates about the venturi body and includes a third air entrainment window and a fourth air entrainment window spaced from the third air entrainment window, wherein registration between the first and third air entrainment windows and the second and fourth air entrainment windows define a degree of air entrainment and the concentration of the supplemental gas delivered to the patient.

Abstract: An apparatus and method for automatically controlling the flow of oxygen from a gas source is provided and includes the step of installing a gas concentrator device on an outlet port associated with the gas source. The gas concentrator device is configured to sealingly mate with a conduit connector for delivering a gas from the gas source to a conduit that is associated with the conduit connector. The method also includes the step of automatically providing gas flow from the gas source to the conduit by sealingly coupling the conduit connector to the gas concentrator device and whereupon removal of the conduit connector from the gas concentrator device causes the gas flow to automatically cease.

Abstract: A modular pulmonary treatment system is provided and includes a patient interface device defined by a body which defines a hollow interior. The system also includes a first inhalation valve associated with the body and located along an inhalation flow path for providing selective fluid communication with the hollow interior of the body; and at least one exhalation valve assembly detachable coupled to the body for discharging exhaled gas from the hollow interior to atmosphere. The at least one exhalation valve assembly comprises: (a) an exhalation valve cartridge including a housing having a perforated bottom wall with a post extending outwardly therefrom; (b) a valve member configured to seat against the perforated bottom wall and including an opening through which the post extends; and (c) a valve retainer for placement over the post, whereby the valve member is securely held in place against the perforated bottom wall.

Abstract: A patient interface system for delivering a gas to a patient includes a patient interface device that includes at least one inhalation valve and at least one exhalation valve. The system also includes a venturi device that has at least one port for connection to a gas source. The venturi device has at least one primary air entrainment window and at least one secondary air entrainment window which is downstream of the at least one primary air entrainment window. The inhalation valve is disposed between: (1) the main body and (2) the primary and secondary air entrainment windows of the venturi device. At least one of the primary air entrainment window and secondary air entrainment window includes a means for closing the respective window, thereby changing a degree at which the respective window is open and changing a flow rate of the air flowing through the respective window.

Abstract: A venturi connector includes a housing having a mixing chamber defined therein and at least one window that is in fluid communication with the mixing chamber and is open to atmosphere to allow air to be entrained into the mixing chamber. The connector includes a nozzle actuator member includes a body having a plurality of discrete nozzles formed therein. The nozzles are defined by different sized venturi orifices through which gas flows, thereby allowing the concentration of the gas delivered to the patient to be varied. The nozzle actuator member is disposed within one window formed in the housing between the gas port and the mixing chamber such that the position of the nozzle actuator member within the housing can be adjusted so as to position one of the discrete nozzles into the gas flow path, thereby controlling the flow rate of the gas into the mixing chamber and ultimately the concentration of gas delivered to the patient.
