A system directed to providing a self-contained negative pressure environment (SCONE) to remove airborne particulates emitted from a patient. The system prevents exposure to pathogenic biological airborne particulates during triage, transportation, and treatment, including aerosol generating procedures (AGPs) and end of life care. This system is directed to a collapsible device having a flexible cover covering two support members, with openings in the flexible cover such that medical professionals can reach in and operate within. The present invention is further adaptable to patients and operating environments of various sizes.

The present disclosure relates to a vehicle-type mobile infectious disease clinic, and more particularly, to a mobile infectious disease clinic, which is a vehicle-type mobile infectious disease clinic, that allows a test subject to be tested by a healthcare provider using an infectious disease test kit while exposure of the body parts is minimized and the healthcare provider and the test subject are isolated in the vehicle-type mobile infectious disease clinic, that performs sterilization of an infectious disease using an ultraviolet C (UV-C) lamp to reduce the time taken for disinfecting the clinic, and that allows the light radiation intensity of the UV-C lamp to be adaptively adjusted according to the body temperature of the test subject.

A collapsible air isolation apparatus is disclosed. The apparatus may include a collapsible frame including a base and a set of rigid panel or soft elements at least partially enclosing a volume of space, where each of the set of rigid or soft panel elements is foldably hinged to at least one of the base or another of the rigid or soft panel elements, and where at least one panel element of the set of rigid or soft panel elements includes an open space for mounting a motor for moving air. The apparatus may include mounting system attached to the base.

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.

A controlled access aerosolized particle enclosure for isolation of airborne contaminants includes a frame defining a patient isolation region over a patient bed. A linkage attaches the framed enclosure to a patient treatment vehicle, and a flexible elasticized barrier is suspended by the frame for enclosing the patient isolation region. The barrier is formed from deformable planer sheets of a flexible transparent material and extending adjacent to the patient treatment surface forming a draped edge around the bed or transport. A low pressure source is in fluidic engagement with the enclosure for reducing a pressure within the enclosure below that of ambient surroundings, such that the low pressure source provides a pressure for drawing the elasticized barrier against the patient treatment surface for restricting airborne particle passage from the enclosure to the ambient surroundings, but limits the negative pressure to avoid substantial deformation or collapse of the enclosure.

Many pneumonia diseases and lung malfunctions can be quickly repaired using an improved lung lavage technique where the patient is rotated in specific 3D orientations to increase the efficiency of the lavage procedure. The process involves filling and emptying the lungs with fluid and rotating the patient makes this process natural and effective. Supplementary, a hydro-pneumatic system facilitates the operations with the patient sustained in various positions such as being immersed in water and having various control mechanisms such as variable pressures, temperatures, and performing assisted breathing. Additionally, immersed devices are implanted that shake-up of alveolar wall and other devices perform ultrasound imaging with a 0.1 mm resolution, a resolution in competition with stereoscopic X-ray. The bio-medical data acquisition system allows physicians to completely assess patient status in real time and guide the treatment to ensure optimum patient care, under quality assurance procedures.

A lower body negative pressure device is provided. The lower body negative pressure device includes an internal frame that surrounds a patient's lower body when the patient is in the lower body negative pressure device. The lower body negative pressure device includes a flexible cover covering the internal frame to receive the patient and provide a sealable environment. The lower body negative pressure device includes a pressure device coupled to the sealable environment to generate and regulate a negative pressure in the sealable environment when the sealable environment is sealed.

An altitude simulation assembly for an environmental chamber includes: at least one ambient air inlet; an air compressor downstream of said ambient air inlet for compressing the ambient air; at least one gas separation means downstream of the air compressor for separating the compressed air into hypoxic gas and hyperoxic gas; and, at least one fluid flow control means in fluid communication with the at least one gas separation means, for controlling the flow of hypoxic gas and hyperoxic gas to the environmental chamber. The at least one fluid flow control means is in fluid communication with at least one outlet port for supplying hypoxic gas from the gas separation means to the at least one outlet port, and hyperoxic gas from the gas separation means to the at least one outlet port.
