A pressure safety device is used with a bag valve mask (BVM) for preventing over-pressurization. The BVM includes a bag assembly having a bag connector for detachably mating to a mask connector on a patient mask. The pressure safety device has a housing with a bag port, a mask fitting, and a flow path from the bag port to the mask fitting. The bag port detachably connects to the bag connector on the BVM, and the mask fitting detachably connects to the mask connector on the BVM. The pressure safety device includes an automatic flow reduction valve located on the flow path in the housing and impedes flow when pressure on a bag connector side of the valve exceeds a maximum threshold value.

A therapeutic gas source and cart and methods thereof for use with a therapeutic gas delivery system is disclosed. The therapeutic gas source may include a cylinder operable to contain a therapeutic gas that includes a body and a gas source valve body. In some examples, the gas source valve body has a valve and a coupling member.

A ventilation device for providing a gas mixture for a user including a compressor to output compressed air; a valve to receive the compressed air and medical gas and selectively output a gas flow of at least one of the medical gas and the compressed air; a patient interface configured to provide the output gas flow of the valve; and a controller to control the valve to deliver substantially only the medical gas to the patient interface during a first portion of the inspiratory period and deliver substantially only the compressed air to the patient interface during a second portion of the inspiratory period.

A ventilator that moves breathable air into and out of the lungs of a patient. The ventilator includes an inspiratory circuit with an inlet, a bellows, and an outlet port for moving air into the lungs of the patient. An expiratory circuit includes an inlet port and a discharge port for moving the air out of the lungs. The inspiratory circuit is adjustable to control a number of breathes per time period and a volume of the breaths.

An apparatus for pressurizing one or more airways of a user, including: a dental arch mold configured to receive a plurality of teeth, a port which may be at a front face of the dental arch mold, a first nasal pillow, a second nasal pillow, a multi-output air regulator, and a plurality of sensors. The multi-output air regulator and sensors allow the airway pressurization device to sense the pressures in as well as be in independent fluid communication with the port of the dental arch, the first nasal pillow, and the second nasal pillow, such that an equalization of pressures, or a determined pressure differential between each may be obtained.

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 breathing device, comprising a mouthpiece forming a breathing channel, to form a connection between a first end and a second end of the mouthpiece; the first end being configured for a user breathing into the mouthpiece through a breathing opening; an at least partly flexible rebreathing air chamber attached to the second end of the mouthpiece, thereby being in fluid connection with the breathing channel; the rebreathing air chamber being formed by at least partly flexible wall section(s), the at least partly flexible rebreathing chamber having at a first wall section, being permeable to gas by a plurality of pores provided in said wall section and/or the mouth piece comprising one or more though going openings.

A manually operable valve for restricting airflow to and/or from a patient. The valve includes a body having one or more walls that extend between a first end and a second end. The one or more walls form a passage between the first end and the second end of the body. Two moveable members are positioned on opposing sides of the passage and axially fixed between the first end and the second end of the body. The two moveable members are configured such that depressing the two moveable members inwardly deforms the one or more walls to thereby restrict the passage. When the two moveable members are subsequently released, the one or more walls return to unrestrict the passage.

A system and method for performing a bronchoscopy. The system may include a bronchoscope, a multi-fluid conduit apparatus, and a switching apparatus. The bronchoscope may include an insertion tube having a distal end, a control section, and a working channel. The multi-fluid conduit apparatus may include a first conduit section operably coupled to a vacuum source, a second conduit section operably coupled to an oxygen source, and a third conduit section operably coupled to the working channel, each of the first and second conduit sections being fluidly coupled to the third conduit section. The switching apparatus may include a valve apparatus operably coupled to each of the first and second conduit sections and an actuator apparatus operably coupled to the valve apparatus. The actuator apparatus may alter the valve apparatus between: (1) a suction supply state; and (2) an oxygen supply state.

A lung isolation tube assembly comprising a control valve that is adapted to be moved between a left lumen position, a right lumen position, and a both lumens position, a connector that is in fluid communication with the control valve and having a port, and a tube that is in fluid communication with the connector. The tube comprises a left lumen that is in fluid communication with the connector and a right lumen that is in fluid communication with the connector. The assembly also comprises a first cuff that is disposed around a portion of the right lumen and the left lumen and a second cuff that is disposed around the left lumen. The assembly is adapted to convey airflow or oxygen to a human lung via at least one of the left lumen and the right lumen. A method for isolating a human lung.
