An oxygen concentrator comprises a product tank that is fluidly coupled to at least one sieve bed, and a product gas accumulator tank that is fluidly coupled to the product tank via a first conduit and to an outlet port via a second conduit, wherein the first conduit and the second conduit are disposed to allow at least a portion of product gas to flow from the product tank to the outlet port.

A sedation device has a housing divided internally into a ventilator chamber and an associated evaporator chamber which overlap and are separated by a filter mounted between the chambers and forming a common gas-permeable dividing wall between the chambers. An inlet port is provided at one end of the ventilator chamber at a top of the housing for connection to a patient ventilator in use. An outlet port on the evaporator chamber can be connected via a breathing tube to a patient. An evaporator is mounted within the evaporator chamber for delivery of a volatile sedative into the evaporator chamber during use.

A respiratory therapy apparatus is operable to deliver multiple types of therapy to a patient. The apparatus includes a main housing and a nebulizer tray that selectively attaches to a bottom of the main housing. The apparatus also includes a filter housing unit having an antenna surrounding a pneumatic passage and a transponder chip coupled to the antenna. The main housing has also has an antenna that surrounds a respective pneumatic passage of a main outlet port of the apparatus. The main housing includes a reader that controls communication between the antennae. The main housing of the apparatus also has a pivotable hose support plate, a firmware upgrade port underneath part of the top wall of the housing, and a graphical user interface (GUI) that displays various user inputs for control of the apparatus and that displays various alert conditions that are detected.

A gas conduit for respiratory apparatus includes a lumen for passage of a breathable gas to a patient and a flexible conduit wall surrounding the lumen. The flexible conduit wall has a humidification apparatus for delivering water vapour into the gas passing through the lumen.

Provided is a ventilator that includes a breathing system, a mechanical system coupled to breathing system, and a control system coupled to breathing system and mechanical system. The control system includes pressure sensors, processing circuitry, and memory configured to store a look-up table. The processing circuitry receives a set of values for plurality of parameters, identifies a compression value from a plurality of compression values in the look-up table based on the received set of values. The processing circuitry causes the mechanical system to compress a bag valve of the breathing system in accordance with the identified compression value. The compression of the bag valve causes a gaseous inhalant to flow through the breathing system within a time-interval. The processing circuitry determines an actual volume of the gaseous inhalant and iteratively modifies the compression value of the bag valve to match a desired volume of the gaseous inhalant.

An apparatus having an adjustable ambient air-oxygen blender that adjustably mixes ambient air with an oxygen supply, especially where a size, diameter or flow rate of an orifice is mechanically adjustable so as to control a quantitative mixing function of the blender.

The present invention relates to an exhaust apparatus for releasable or permanent connection to a personal protection respiratory device that defines a filtered air volume adjacent to the face of a wearer and comprises at least one exhalation valve. The exhaust apparatus comprising a powered blower in fluid connection with the at least one exhalation valve, the blower being operable to draw a portion of the wearer's exhaled breath through the at least one exhalation valve. Using such an exhaust apparatus for releasable connection to a personal protection respiratory device improves the comfort and overall experience for respirator wearers who use the respirator for intensive work, and/or for long periods of time, and/or in hot and humid environmental conditions by removing the heat and moisture build-up inside the respirator.

The present disclosure is directed to a plurality of air quality devices configured to be held in a user's mouth and configured to increase at least one of humidity and temperature and constitution of air inhaled. There are passive and active systems that allow for improved physical and lung performance.

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.
