A method and system for separating a flow of matter is shown and described. The system includes one or more flow separation devices, one or more surgical instruments, and one or more suction sources. In some embodiments, the flow of matter comprises biological material. In some embodiments, the flow of matter comprises surgical waste.

An apparatus is provided to change the absolute humidity of a flow of air for delivery to an entrance of the airways of a patient, the change being compared to the absolute humidity of ambient air. The apparatus has a reservoir configured to hold a volume of liquid. A heating element creates vapour from the liquid. A chamber is provided to mix the flow of air with the vapour. The apparatus has a body having a first wall structure with a chamber inlet port. A closure element having an air inlet port for pneumatically connecting to a source of the flow of air is secured to the body to provide a sealed gas flow path between the air inlet port and the chamber inlet port, and a liquid trap in the gas flow path.

An inhalation-synchronized fluid product dispenser device having a body (10) provided with a mouthpiece (400), a product reservoir (100) containing fluid product, and a dispenser mechanism (200). The device has a blocking mechanism (500; 600) for the dispenser mechanism and an inhalation-controlled trigger system having an inhalation-sensitive member (60) deformable and/or movable by inhalation, the inhalation-sensitive member co-operating with the blocking mechanism so that when deformed and/or moved, it enables the dispenser mechanism to be actuated. The device has a protective element (1) the trigger system, the protective element disposed between the mouthpiece and the inhalation-sensitive member and made of a porous material that allows air to pass through it but blocks the passage of water, dust and foreign bodies.

The invention relates to a device for the dynamically adapting sealing of an organ or a body cavity, e.g. the windpipe (trachea) of an intubated and ventilated patient, wherein the sealing balloon element is produced via particularly rapid shifting of filling medium from an extracorporeal reservoir or an extracorporeal source to the sealing balloon, and wherein, in the dynamic sealing of the trachea according to the example case, a balloon-type foil body preferably formed with residual material in the diameter, i.e. exceeding the tracheal diameter, is in contact with the inner wall of the trachea in a sealing manner and with a pressure that is as constant as possible, wherein fluctuations in the balloon volume, caused by fluctuations in the intrathoracic pressure relating to the mechanics of breathing, are compensated as quickly as possible by supplying volume from an extracorporeal reservoir or an extracorporeal source, and the tracheal secretion sealing of the balloon is thereby kept continuous. This is both made possible by a sufficiently high-volume supply of the balloon filling medium to the cuff, and also prevents steps, gaps or ridges in the supply system, whereby volume flow directed towards the balloon can be minimised, which is crucial for a rapid-as-possible stabilising of the filling volume in the balloon, in particular with small pressure differences between 15 and 30 mbar that are driving the volume flow.

Technologies for sanitizing medical devices are described. In particular, sanitizing systems, components of sanitizing systems, and methods for sanitizing medical devices such as continuous positive airway pressure (CPAP) equipment are described. In embodiments, the sanitizing systems include a sanitizing gas generator and a base including at least one exhaust port and a filter.

A patient interface is configured to deliver a pressurized flow of respiratory gas to a patient's airways. The patient interface includes a cradle base configured to cradle the patients nose in use. Two protrusions extend from the cradle base and are configured to be inserted into the patients nares in use. Each of the protrusions have formed therein an opening configured to allow a continuous flow of air therethrough. In addition, a plenum base forms a plenum chamber together with the cradle base. The cradle base is configured so that movement of the cradle base is decoupled from the plenum base.

An airborne pathogen extraction system that provides for continuous airborne pathogen particle extraction from a specifically targeted area in a room or a specifically targeted area proximate to a user. The pathogenic particles are filtered and/or disinfected before the air is returned proximate to the originating location, or are directed an area away from the user(s). The airborne pathogen extraction systems and methods lower the chances of contagion or infection from airborne pathogens, such as viruses.

An oxygen concentrator may have a compressor to feed a feed gas for sieve bed(s) via a first manifold, an accumulator to receive enriched air from the bed(s) via a second manifold. It may include an outer housing for the manifolds, the compressor, and the accumulator. The housing may include an access portal to a compartment therein, for removably receiving the bed(s) as a canister assembly. The first manifold may be adjacent to the compartment and have inlet coupling(s) for removably coupling respectively with inlet(s) of the canister assembly. The inlet coupling(s) may each have a first central axis. The second manifold may be adjacent to the compartment and have outlet coupling(s) for removably coupling respectively with outlet(s) of the canister assembly. The outlet coupling(s) may each having a second central axis. The first and second central axes may form any one of an obtuse, acute, or right angle.

A patient interface comprising a cushion having a nasal plenum chamber, an oral plenum chamber, and a passage formed between the nasal and oral plenum chambers. The passage is configured to allow airflow to pass between the nasal and oral plenum chambers. The cushion also includes a valve including valve body and an adjustment structure that is positioned between the nasal chamber and the oral chamber and is movable relative to the valve body. The adjustment structure is movable between an open position that is configured to allow airflow between the nasal plenum chamber and the oral plenum chamber, and a closed position configured to limit airflow between the nasal plenum chamber and the oral plenum chamber. The adjustment structure is configured to allow airflow through a nasal vent in the closed position and is configured to limit airflow through the nasal vent in the open position.

A system for delivering a therapeutic amount of nitric oxide can include a reservoir containing a nitrogen dioxide source. A heating element can be configured to heat the reservoir, causing nitrogen dioxide vapor to exit the reservoir through a restrictor into a conduit. The nitrogen dioxide vapor can mix with gas from a gas supply, which can then flow to a cartridge that includes a surface-activated material saturated with an aqueous solution of a reducing agent. The cartridge can convert the nitrogen dioxide into nitric oxide.
