In accordance with the present invention, there is provided an adaptor or attachment which is suitable for integration into the patient circuit of a ventilation system, such as a non-invasive open ventilation system, is configured for attachment to any standard ventilation mask, and is outfitted with a jet pump which creates pressure and flow by facilitating the entrainment of ambient air. The adaptor comprises a base element and a nozzle element which are operatively coupled to each other. The base element further defines a throat and at least one entrainment port facilitating a path of fluid communication between the throat and ambient air. The nozzle element includes a jet nozzle, and a connector which is adapted to facilitate the fluid coupling of the nozzle element to a bi-lumen tube of the patient circuit. The connector includes both a delivery port and a sensing port. The jet nozzle and the delivery port collectively define a delivery line or lumen which fluidly communicates with the throat of the base element, and is placeable into fluid communication with the delivery lumen of the bi-lumen tube.

A ventilator system configured to switch between one or more invasive ventilation modes and one or more non-invasive ventilation modes is provided, the ventilator system comprising: an externally pressurized source of pre-mixed gas comprising air and oxygen; one or more inspiratory valves configured to deliver incoming pre-mixed gas to a patients breathing circuit; and one or more expiratory valves configured to remove outgoing gas from the patients breathing circuit; wherein in the one or more invasive ventilation modes, the inspiratory valves and the expiratory valves are configured to open and close to allow or prevent the passage of gas as needed in order to enforce a respiration cycle within the patient; and wherein in the one or more non-invasive ventilation modes, the inspiratory valves and the expiratory valves are kept open in order to allow the gas to pass freely through the system.

The present disclosure provides for a control system for a flow therapy apparatus. The control system can control delivery of a fraction of delivered oxygen (FdO2) to a patient. The control system can maintain the FdO2 at a target level during a therapy session. The control system can automatically control an oxygen inlet valve in order to control the flow of oxygen to the patient.

A humidification device that includes a case containing a humidification space in which water vapor is introduced to a feed gas to be fed to a user. heating unit configured to acquire electric energy using an electromagnetic induction phenomenon to generate heat is disposed in the humidification space. The humidification device further includes a coil configured to transfer energy to the heating unit by the electromagnetic induction phenomenon, an insulating unit configured to spatially separate the heating unit and the coil to prevent electrical contact therebetween and a liquid supply unit configured to supply, to the heating unit, a liquid to be vaporized into the water vapor. This provides a humidification device that can be made smaller in size and lighter in weight, and that can quickly and sufficiently humidify a gas without heating an entire body of water to be stored, as well as a respiratory assistance device.

Therapy gas delivery systems that provide run-time-to-empty information to a user of the system and methods for administering therapeutic gas to a patient. The therapeutic gas delivery system may include a gas pressure sensor attachable to a therapeutic gas source that communicates therapeutic gas pressure data to a therapeutic gas delivery system controller, a gas temperature sensor positioned to measure gas temperature in the therapeutic gas source that communicates therapeutic gas temperature data to the therapeutic gas delivery system controller, at least one flow controller that communicates therapeutic gas flow rate data to the therapeutic gas delivery system controller, at least one flow sensor that communicates flow rate data to the therapeutic gas delivery system controller, and at least one display that communicates run-time-to-empty to a user of the therapeutic gas delivery system. The therapeutic gas delivery system controller of the system includes a processor that executes an algorithm to calculate the run-time-to-empty from the data received from the gas pressure sensor, temperature sensor, flow controller and flow sensor, and directs the result to the display.

The Intelligent Automatic Oxygen Therapy System provides a device that allows the automatic and intelligent dosage of the percentage of an oxygen/air gas mixture and the flow delivered to each patient through non-invasive oxygen therapy procedures, based on the analysis of several measured variables that confirm the SpO2 value before taking any action. This device allows to measure biomedical signs with the main object of monitoring the oxygen saturation (SpO2), confirming its value with the analysis of the mentioned signs according to their concordance and interrelationship with each other. The equipment through artificial intelligence detects events that can occur due to the movement or for misplaced sensors. It also keeps and analyzes the records of the patient, evaluates the alarms in an intelligent way by correlating all acquired data; with this analysis the equipment can automatically and reliably provide the oxygen/air mixture adequate for each patient, with five operation modes. It activates the processed and valid alarms in an intelligent way and informs in a timely manner to the personal staff about possible found pathologies.
