Systems and methods are provided for detecting and sequestering waste anesthetic gases released by an anesthetic vaporizer. In one embodiment, a method for an anesthetic vaporizer installed in an anesthesia machine includes detecting an emission of waste anesthetic gases (WAGs) from the anesthetic vaporizer, and responsive to detecting the emission of WAGs, performing at least one of scavenging the WAGs and outputting an alert.

A smart mask includes a face covering, an attachment member, one or more sensors, and a controller. The face covering is configured to cover a face area of a wearer. The attachment member is configured to attach the face covering onto the face area of the wearer. The one or more sensors comprises an air quality sensor configured to obtain first data associated with nearby air quality or a breathing pattern sensor configured to obtain second data associated with the wearer's breathing pattern. The controller is configured to process the first data associated with nearby air quality to identify a current air quality, or process the second data obtained by the breathing pattern. In response to determining that the current air quality is worse than a predetermined threshold, or identifying a particular breathing pattern, the controller is configured to generate a notification, notifying the wearer.

A device includes a body defining a respiration passage in fluidic communication with a filter fitting disposed on a first end of the body and a mask fitting disposed on a second end of the body, and a treatment passage in fluidic communication with the mask fitting. A treatment fitting is disposed on the body and is coupleable to a treatment source such that a seal in the treatment fitting transitions from a closed state to an open state to allow fluidic communication between the treatment source and the treatment passage. The device configured to permit (i) inhalation air and/or exhaled breath to be drawn and/or expelled through the filter fitting, the respiration passage, and the mask fitting and (ii) a respiratory therapeutic to be drawn from the treatment source coupled to the treatment fitting, through the treatment passage, and through the mask fitting.

A nebulizer assembly for a respiratory device is provided having a housing defining a chamber. The housing also has a nebulizer port configured to receive a nebulizer to discharge atomized medication into the chamber. An outlet of a handle is coupled to the inlet of the housing. A hose is coupled to an inlet of the handle. A patient interface is coupled to the outlet of the housing. Air flows from the hose to the patient interface via the handle and the housing. The air mixes with the atomized medication within the chamber.

The present disclosure provides methods and systems for treating a biological fluid of a subject suffering from a microbial infection (e.g., a drug-resistant microbial infection). In some embodiments, these methods and systems involve a complement receptor immobilized on, or otherwise associated with a polymer substrate, for example, high surface area particles, membranes, hollow fibers, and/or other porous or non-porous media. In other embodiments, the methods and systems involve a complement receptor present in a dialysate used in a dialyzer for extracting pathogens out of a biological fluid, for example, the blood of a patient.

A filter assembly for filtering a flow of incoming air entering a pressurized breathing gas system includes a filter housing and a filter media. The filter media includes a filtering section and a non-filtering section. The filter housing is structured to be inserted within a pressure generating device used in the pressurized breathing gas system. The filtering section is disposed within the filter housing and is structured to filter contaminant matter from the flow of incoming air. The non-filtering section is disposed outside of the housing and is structured to be separated from the filtering section so as to not make contact with the flow of incoming air. The filtering section and the non-filtering section are structured to be visually compared to one another such that a contaminant matter saturation level of the filter media can be determined.

The present disclosure provides, among other things, methods and systems for treating or removing blood clots in a biological fluid. In some embodiments, the present disclosure provides dialysis-like systems for capturing blood clots. The present disclosure encompasses the recognition that such methods and systems are useful for patients at risk for pulmonary embolism (e.g., patients with deep vein thrombosis and/or COVID-19 patients).

A noise reduction device (100) for a respiratory apparatus (162) including a body (104) with a gas outlet (106) arranged to be mounted on the gas inlet (164) of the respiratory apparatus (162), and a cover (102) configured to be detachably engaged with the body (104) for forming a gas inlet (156) and a gas passage (138). The cover (102) includes a guiding member (136) to define at least a part of the gas passage (138) and the guiding member (136) is configured to be coupled with the body (104) to form the gas passage (138) between the body (104) and the cover (102). The noise reduction device (100) in the present invention provides a longer and smooth passage (138) for the gas to flow from the gas inlet (156) to the gas outlet (106) for reduction of turbulence and resistance of gas flow and hence reducing the noise caused by the friction between the fluctuated gas flow and the gas inlet (164) of the respiratory apparatus (162).

A method for operating a humidifier coupled to a gas flow generator. The humidifier has a pump providing a supply of water to a heater plate. The method includes: providing power to the gas flow generator; raising the temperature of the heater plate from an ambient temperature to about a first predetermined temperature; powering the pump at about a predetermined first duty cycle; monitoring the temperature of the heater plate until one of: a drop in temperature is detected, or a predetermined period of time has elapsed; and one of: increasing the duty cycle of the pump if the drop in temperature is detected, or turning off the pump if the predetermined period of time has elapsed.

A respiratory apparatus (100), comprising: a first gas inlet (202) for supplying a first gas to the respiratory apparatus (100); a second gas inlet (206) connectable to a pressurized gas source to supply a pressurized gas; a mixing chamber (204) for mixing the first gas and the pressurized gas; and a noise-damping member (216) disposed downstream of the mixing chamber (204).
