A respiratory system, primarily to provide a mechanical insufflation/exsufflation therapy, may include a first pressure generating source, a second pressure generating source and a primary valve to switch between insufflation/positive pressure flow and exsufflation/negative pressure flow, and to generate oscillations alongside either of these cycles. The respiratory system can optionally employ a secondary valve either on a fluidic path of the first pressure generating source or on a fluidic path of the second pressure generating source. An interfacing assembly acts as a fluidic conduit between the pressure generating sources and the patient. A control unit is configured to generate required pressurized flow and oscillations as per the user settings. The aforesaid valves can be manipulated into multiple orientations/positions, which are aligned and/or adjusted with respect to the respective pressure generating sources as per the therapy requirements.

An apparatus for delivering a flow of gas has a housing, a cover, and a magnetic coupling system arranged to magnetically couple the cover—to the housing. Each of the housing and cover having complementary locating features, the locating features being adapted to locate and align the cover and the apparatus relative to each other to allow for the magnetic coupling. The apparatus also has a handle movably connected to the housing and is movable from a first position to a second position. The housing and the handle comprise complementary interlock features arranged to engage with each other when upward force is applied to the handle in the second position, and the interlock features are disengaged from each other when the handle is in the second position but upward force is not applied to the handle.

This disclosure enables displaying of an intuitive and engaging enquiry on a touchscreen of a medical device (e.g., breathing apparatus, breathing assistance apparatus) that a patient is already using (e.g., in-home medical device). Since the patient is already accustomed to using the medical device for medical treatment control, the patient, who may be unwell, is more likely to access the enquiry and complete the enquiry. Further, making the enquiry intuitive and engaging encourages the patient to regularly interact with the enquiry, while ensuring that the enquiry is not overly tedious to complete. Responding to the enquiry can be made mandatory by refraining from activating or preventing activation of a component of the apparatus until a predetermined set of responses has been received.

Resuscitation/ventilation systems that include a pressure chamber or cylinder may use a piston articulated within the pressure chamber or shaft to push air and/or a mixture of gas and air into and out of an airway circuit for the purpose of providing mechanical ventilation and/or artificial respiration to a patient. In some cases, the pressure chamber or cylinder may be resident within a canister that fits with a body. The canister may include a motor that moves a shaft connected to the piston up and down, or in and out, within the pressure chamber or cylinder and this movement of the piston may cause a vacuum within the airway circuit and/or the pushing of air or gas out of the airway circuit into a patient’s lung(s).

The present invention relates to a method for operating a data processing unit of a ventilation device, and also to a ventilation device. Therapy data are registered and stored in a memory unit and at least a part of the therapy data is transmitted with a transmission unit to a network. At least one available radio network is determined with the transmission unit and at least one parameter for a network quality of the network is defined. At least one processing of the therapy data prior to their transmission into the radio network is carried out dynamically with the data processing unit depending on the parameter.

Described are methods for providing a pulsed dose of a gaseous drug over a portion of total inspiratory time, where the dose of the gaseous drug is delivered at a concentration of nL of gaseous drug per mL tidal volume.

Methods and apparatus may implement controlled generation of oxygen enriched air in an oxygen concentrator while implementing control that reduces pneumatic imbalance between the concentrator's canisters, such as dynamic pressure imbalance or other pneumatic characteristic. One or more controllers may regulate operation of a compressor that feeds a pressurised air stream to the concentrator's canisters. This may regulate speed of the compressor to a speed set point for generating the pressurised stream. The regulating may involve generating a compressor control signal having a characteristic parameter such as a power parameter. The controller(s) may operate valve(s) in a cyclic pattern so as to produce oxygen enriched air in an accumulator. A cycle of the cyclic pattern may include a plurality of phases, where each of the plurality of phases has a duration. The controller(s) may then generate a dynamic adjustment to the duration(s) based on an evaluation of the characteristic parameter.

Various control methods can indirectly determine incorrect connections between components in a respiratory therapy system. For example, errors in the connections can occur between a patient interface, a humidifier and/or a gases source. The methods can indirectly detect if a reverse flow condition exists or other error conditions. A reverse flow condition can occur when gases flows in a direction different from an intended direction of flow. The detection of the reverse flow condition can be indicative of likely errors in connections between the humidifier, patient interface and/or gases source.

The present disclosure provides a ventilator that includes a first gas path, comprising a first pressurized gas source adaptor and a first flow adjustment device connected in sequence; a second gas path, comprising a second pressurized gas source adaptor and a second flow adjustment device connected in sequence; a third gas path, comprising a third pressurized gas source adaptor; a first inhalation branch for delivering inhalation gas to a patient; a second inhalation branch for delivering inhalation gas to the patient, including a gas compression device; a switching device, including a first mixing mode connecting the first gas path and the second gas path to the first inhalation branch, and a second mixing mode connecting the first gas path and the third gas path to the second inhalation branch; and an exhalation branch for managing exhaled air of the patient.

Devices for delivering a controlled concentration of an agent are provided. The device includes a reservoir for the agent and a flow control portion operably connected to the reservoir. The device also includes a valve for releasing the agent from the flow control portion and a pump for flowing air to mix with the agent released by the valve and for flowing the agent and air mixture out of the device. Methods of delivering a vaporized agent to a subject are also provided. The methods include storing a liquid agent in a reservoir of a device and flowing the agent into a flow control chamber to change the agent to a gas. The methods also include mixing the agent in gas form with air and flowing the agent and air mixture out of the device to be delivered to a subject.
