Modular ventilatory support systems and methods are disclosed in which a user may transition the system between a stationary configuration, an extended range configuration, and a stand-alone configuration. The modular components of the system include a compressor unit, a ventilator which may dock with the compressor unit, and a patient interface which may be connected to either the compressor unit or the ventilator unit. By rearranging these modular components into different configurations, mobility and duration of use may be optimized to fit the present needs. In the stationary configuration, mobility is most restricted, but duration of use is maximized. In the extended range configuration, mobility is enhanced, with duration of use limited by the battery power of the ventilator. In the stand-alone configuration, mobility is maximized, with duration of use limited by battery power of the ventilator and the quantity of an external gas supply.

Modular ventilation system

A patient circuit of a ventilation system, such as a non-invasive open ventilation system, wherein the patient circuit comprises a nasal pillows style patient interface that incorporates at least one 'Venturi effect' jet pump proximal to the patient. The patient circuit further comprises a pair of uniquely configured 3-way connectors which, in cooperation with several uniquely configured tri-lumen tubing segments, facilitate the cooperative engagement of the patient interface to a ventilator of the ventilation system.

Patient interface with integrated jet pump

The present technology is directed to ventilator systems that can provide both ventilation therapy and oxygen therapy. The systems described herein may include a ventilation assembly that can provide inspiratory gas to a patient circuit and an oxygen assembly that can provide pulses of oxygen to an oxygen delivery circuit. In some embodiments, the oxygen delivery circuit is distinct from the patient circuit. For example, the patient circuit can include a corrugated conduit coupled a ventilation mask, and the oxygen delivery circuit can include a nasal cannula. The ventilation mask can be positioned over the nasal cannula so that the patient can receive both the inspiratory gases and the pulses of oxygen.

Ventilator systems with integrated oxygen delivery, and associated devices and methods

A portable medical ventilator using pulse flow from an oxygen concentrator to gain higher oxygen concentration includes a positive pressure source to deliver pressurized air to the patient and a negative pressure source to trigger the oxygen concentrator. A patient circuit attached to a patient interface mask connects the ventilator to the patient. The ventilator includes a controller module that is configured to generate a signal to the negative pressure device to trigger the concentrator to initiate one or more pulses of oxygen from the oxygen concentrator. The oxygen pulses are delivered to the patient interface directly through multi-tube or a multi lumen patient circuit. The oxygen does not mix with air in the ventilator or in the patient circuit and bypasses the leaks in the patient circuit and/or patient interface.

Portable medical ventilator system using portable oxygen concentrators

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.

Jet pump adaptor for ventilation system

A continuous positive airway pressure (CPAP) apparatus for respiratory assistance of a patient is disclosed. There is a blower having an output connectible to a ventilation mask wearable by the patient. A first pressure sensor measures blower pressure at the output of the blower, and a second pressure sensor that is connectible to the ventilation mask measures mask pressure therein. A pressure controller is connected to the first pressure sensor and the second pressure sensor, and a patient inspiratory phase and a patient expiratory phase is be detectable by the pressure controller to regulate therapeutic airflow delivered to the patient based upon pressure differentials between the mask pressure and the blower pressure.

Dual pressure sensor continuous positive airway pressure (CPAP) therapy

A method for controlling a ventilator includes the steps of providing an inhalation pressure limit, determining when a pressure in a connection to a patient circuit is greater than the inhalation pressure limit, and opening the valve when the pressure is greater than the inhalation pressure limit. An associated computer readable medium for controlling the method is also described.

Active valve for ventilators

A respiratory assistance device includes a patient interface for coupling to a patient respiratory passageway, and a selectively regulated therapeutic gas flow source in pneumatic communication with the patient over the patient interface. A ramping controller is connected to the therapeutic gas flow source and is receptive to inputs of a prescription pressure level, an initial pressure level, a total ramp duration, and a numeric value corresponding to a ramping duration. Therapeutic gas flow at an initial pressure level is regulated for a ramp delay duration reciprocal to the ramping duration relative to the total ramp duration. The ramping controller incrementally increases therapeutic gas flow to the prescription pressure level from a ramp start time to a ramp end time at a delivery pressure increase rate derived from the numeric value of the ramping duration and the total ramp duration.
