A filter for an apparatus for delivering a flow of gas, the filter comprising: a filter body, wherein the filter body has a main compartment and a sub-compartment at least partly within the main compartment, wherein the main compartment is in fluid communication with a main compartment gases inlet and the sub-compartment is in fluid communication with a sub-compartment gases inlet; and a filter medium associated with both the main compartment and the sub-compartment, and that is arranged to filter gases in, or exiting, the main compartment and the sub-compartment.

A respiratory device may include an inlet port and an outlet port. A fluid pathway may extend between the inlet port and the outlet port. A filter housing may be positioned between the inlet port and the outlet port. A filter may be positioned within the filter housing. A first pressure port may be positioned on an inlet side of the filter housing. A second pressure port may be positioned on an outlet side of the filter housing. The first pressure port and the second pressure port may extend parallel to the fluid pathway. A pressure transducer may be coupled to the first pressure port and the second pressure port and configured to measure a pressure drop between the first pressure port and the second pressure port.

A cartridge system comprising a container and at least four cartridges for generating oxygen, a compressor for compressing the generated oxygen, at least one storage tank configured to store the compressed oxygen received from the compressor, an oxygen pressure regulator enabling a uniform flow of oxygen at pre-defined oxygen pressure, an oxygen flow control knob regulating flow ratio of the oxygen being supplied to the patient in an instant, a humidifier means imparting humidity to the oxygen being supplied to a patient, and a display unit displaying a set of information associated with the system and communicatively coupled to the portable oxygen generator system 10 via wireless network. The cartridges may be triggered in a plurality of ways to maintain a continuous outflow of generated oxygen for a longer duration. Further, the operation of the system may be monitored or controlled wirelessly from a distant location.

A humidifier is for an airway pressure support system for delivering a humidified flow of breathing gas to an airway of a patient. The humidifier includes a water chamber, a filter, a filtration meter, a conduit, a nozzle, and a heater plate. The filter has a housing structured to house a filtration medium therein and having an inlet fluidly connected with the water chamber and an outlet. The filtration meter includes an inlet fluidly connected to the outlet of the filter, an outlet, a body portion extending between the inlet and the outlet which is structured to convey water from the inlet of the filtration meter to the outlet of the filtration meter, and a mechanism located in the body portion which is structured to measure filtration data of the water conveyed through the body portion.

An absorption system (100) and a process for absorption of gas from a medical apparatus (1) are provided. The absorption system includes a feed line (6), a discharge line (8), a filter unit (4) with a filter and at least one buffer storage device. The feed line establishes a fluid connection between the medical apparatus and the filter unit. The discharge line establishes a fluid connection between the filter unit and a fluid absorption unit (7). The gas is discharged from the medical apparatus and is passed through the feed line to the filter unit and from there through the discharge line to the fluid absorption unit. The filter filters at least one gas component out of the gas that is passed through the filter unit. The one or more buffer storage device absorbs and again discharges gas from time to time.

A method for controlling a ventilator to provide variable volume (VV) with average volume assured pressure support (AVAPS), including: producing a VV target volume using a VV distribution function; producing a volume error Verror that is the difference between the VV target volume and a measured volume of the previous breath; scaling the volume error Verror; producing a VV target difference as the difference between VV target volume and the VV target volume of the previous breath; producing a modified volume error by adding the VV target difference to the scaled volume error Verror; producing a delta pressure support ΔPS based upon the modified volume error and a dynamic compliance; and producing a current pressure support value based upon the delta pressure support ΔPS and the pressure support value of the previous breath.

Disclosed herein is a molecular imprinted protective face mask comprising a supportive structure, a surface material that receives and retains a molecular imprint and that is positioned to contact airborne molecules during use, a molecular imprint of a bioactive molecule wherein an imprinted cavity is at least one of a bioactive molecule with a molecular configuration that captures a specific airborne and/or microdroplet-borne molecule and a protein with a binding site that captures a specific molecule.
