The present disclosure generally relates to systems and methods for delivery of therapeutic gas to patients, using techniques to compensate for disruptions in breathing gas flow measurement, such as when breathing gas flow measurement is unavailable or unreliable. Such techniques include using historical breathing gas flow rate data, such as moving average flow rates, moving median flow rates and/or flow waveforms. At least some of these techniques can be used to ensure that interruption in therapeutic gas delivery is minimized or eliminated.

Described here are closed-circuit breathing devices and methods for their use. In general, the closed-circuit breathing device is configured to achieve a steady-state equilibrium, whereby therapeutic gas is introduced into the breathing circuit in small, controlled volumes until a steady state concentration of the therapeutic gas is reached. During this time, the closed-circuit breathing device is operated in a true closed circuit, such that the therapeutic gas is not lost to the atmosphere. Safety measures are built into the closed-circuit breathing device so that a hypoxic mixture is not delivered to the subject. The therapeutic gas may be xenon.

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.

A display device of an anesthesia machine which is communicable with at least one syringe pump that is an external apparatus displays an anesthesia information display screen. When a call switch is operated, a syringe pump information display screen indicating operation information of the syringe pump is displayed on the display device, in addition to the anesthesia information display screen.

A self-administered oxygenation apparatus for increasing pressure within a non-intubated patient's lungs and thereby increasing an amount of oxygen in the non-intubated patient's blood when operated by the patient includes a mouthpiece, a vent member, a resistance member, and a plurality of medical sensors. The medical sensors are configured to receive a portion of the exhalation and to transmit generated medical data to a remote location, such as to a software application via the internet. The mouthpiece includes an external portion through which the patient inhales and exhales. The resistance member is a PEEP valve configured to open upon inhalation so as to allow ambient air inhaled by the patient to pass thereby without resistance and to close upon exhalation, exhalation causing an end shield to pivot outwardly from the vent member under a bias of external elastic members.

The present disclosure relates to a filter apparatus for filtering liquid from a gas, the apparatus having a first housing having a gas inlet and a gas outlet; a first filter media disposed in the first housing; a second filter media disposed in the housing; and a second housing forming a first collection basin disposed in the flow path between the first filter media and the second filter media, so that a path is defined for the gas flowing from the inlet, through the first filter media, past the collection basin, through the second filter media, and to the outlet. The present disclosure also relates to a method of passing a gas through a coalescing filter media and through a hydrophobic filter media.

Provided is a smart inhaler and wearable smart mask configured to operate as an air ionizer and a controlled multi-liquid atomizer. The smart mask and smart inhaler use a mature technology to deliver various types of liquid solutions to different applications from health care, drug delivery, immunization to recreational and gaming uses. In addition, the smart mask contains multiple actuators to provide haptic feedback to the areas around the mask. The smart mask and inhaler have a direct communication path to a smart device or it can be a smart device by itself; its various environmental and gas sensors act as a feedback mechanism. The detection level of the organic and non-organic VOC gas emitted when exhaling can be communicated and stored for analysis purposes. The detected gas can be regenerated on the same smart mask or a different remote smart mask.
