There is disclosed a method and system for determining the partial pressure of at least one gas in a mixture of gasses contained in a pressure vessel, the mixture being pressurised to a level which is above local atmospheric pressure. The method comprises the steps of positioning a gas analysis sensor (14) within a pressure vessel (10); exposing the sensor to the mixture of gasses at the pressure level found in the pressure vessel; operating the sensor to measure the actual partial pressure of the at least one gas in the mixture contained in the vessel; and periodically calibrating the sensor by directing a calibrating gas mixture (20, 22) to the sensor in the chamber, the calibrating gas mixture being breathable by a human being.

The present invention provides a vented individual negative pressure enclosure system for extracting potentially contaminated air from an individual. The system includes an adjustable assemblable and disassemblable frame structure configured to surround a bed, chair, or toilet. A vapor-impermeable sheet extends over the frame structure. An air purification system communicates with a plurality of extraction vents positioned on or in the frame structure. The air purification system may be a water-filtration-based air purification system including a particle growth tube for increasing the size of aerosol droplets to facilitate capture. The air purification system includes a pump and HEPA filter and, optionally, a UV sterilizer.

An exhaust gas flow control system for an oxygenator of an extracorporeal ventilation system connected to an oxygenation gas supply line and to an exhaust line for removal of exhaust gas comprises a flow control path, a pressure control path, an exhaust flow regulator responsive to the controller, and an exhaust gas pressure regulator responsive to a controller configured to maintain a pre-determined pressure level in the exhaust line. This provides a better degree of control over the pressure across the oxygenator from oxygenation gas inlet to exhaust.

The present application provides a radiation damage protecting agent comprising hydrogen gas as an active ingredient at a concentration of 18.5% by volume or less, for treating or alleviating, in a hyperbaric capsule under a pressure higher than standard atmospheric pressure, radiation damage in a human patient who has been exposed to radiation or who has received or receives radiotherapy, and a hyperbaric capsule for administering a hydrogen gas-containing therapeutic agent such as the radiation damage protecting agent to a patient including a human.

A DAP unweighting system comprising an unweighting assembly and an exercise machine wherein the unweighting system is adaptable to the exercise machine and uses existing framing elements of the exercise machine to achieve an effective and user friendly DAP unweighting system assembly.

Embodiments provide an aeromedical bio-containment module for use in a cargo plane. The aeromedical bio-containment module includes a fully integrated pallet system allowing for the module to roll onto the cargo plane. An integrated set of lugs allows the module to be locked into the cargo plane floor without the use of chains or other pallets. The aeromedical bio-containment module features a ward area for safe treatment of patients, an anteroom, and an office area for personnel. The aeromedical bio-containment module operates under a negative pressure system, and includes a full air filtration system to remove pathogens, particulates, and other airborne contaminants.

The present disclosure relates to a field-type negative pressure isolation room system including main facilities necessary for constructing a negative pressure isolation room defined by the legal regulations, wherein the main facilities are manufactured in a plant in a modular way, so these modular facilities are usually stored in a warehouse, etc., and are installed in an outdoor site such as a parking lot, playground, vacant lot, and the like in case of emergency to utilize as a negative pressure isolation room, and these modular facilities are disinfected and dismantled during demolition and stored in the warehouse again, whereby these modular facilities can be used repeatedly regardless of the number of times of use, and can be quickly constructed and dismantled.

The disclosed infection control systems and devices can be easily and quickly deployed by clinicians and staff in emergent and routine medical environments to provide adequate protection from bio-aerosolized and droplet material while allowing appropriate access to and visibility of the patient during such procedures. The infection control devices may include a base member and a frame disposed on the base member. The frame may be configured to move between a collapsed state and an expanded state with respect to the base member. The frame may include a first support member and a second support member configured to extend vertically from the base member when in the expanded state. The devices may include an enclosure member that is disposed on the frame and the base member and configured to define an enclosure above the base member. The devices may also include access member(s) configured to provide access to the enclosure.

A personal respiratory isolation system (PRIS) provides a personal, negative pressure environment for a patient or user that reduces contamination and spread of pathogens exhaled by the patient into the environment. The PRIS includes an enclosure to receive the patient's head (such as a hood and a drape) and a negative pressure source which draws ambient air into the interior of the enclosure and draws air within the enclosure's interior (including the exhalations of the patient, including any contaminants and/or pathogens) out of the enclosure via a fluid port into a container for biohazard processing or disposal. The PRIS may allow positive air pressure therapeutic treatments to be delivered to the patient within the negative pressure environment, and the PRIS may maintain a constant pressure within the interior of the enclosure. The PRIS may include a transparent, hinged face shield for ease of patient observation and/or access.

Systems and methods for removing material from a blood vessel or cavity inside a body by suction, wherein the magnitude of suction is increased by applying extracorporeal positive pressure. Positive pressure outside the body is increased such that the potential negative pressure inside the body may be increased. Methods include inserting a catheter into a blood vessel or cavity and positioning a distal opening of the catheter proximate the material to be removed. Extracorporeal positive pressure is applied to at least a portion of the body containing the material to be removed, and suction is simultaneously applied to the catheter to more effectively remove the material.
