A universal respiratory detector for detecting a respiratory gas. The universal respiratory detector may include a plurality of layers with a visual indicator to quickly and reversibly change color to detect a respiratory gas parameter such as carbon dioxide. The color change may be visible from both sides of the detector. In some examples, the respiratory detector may be a biocompatible and conformable sticker for mounting on a person's face or an oxygen delivery device.

A shield assembly for providing a barrier adjacent to a patient disposed on a patient support apparatus. The shield assembly comprises a support frame defining a closed periphery and including a resilient element extending along the closed periphery to resiliently urge the support frame toward a bias frame shape. A barrier panel is coupled to the support frame and spans the closed periphery. The shield assembly may further include a base operatively attached to the support frame to selectively place the support frame in a contour frame shape. Tension in the resilient element effected by the base holding the support frame in the contour frame shape places the barrier panel in a curved configuration to define a patient accommodation space shaped to receive the patient adjacent to the base and to the barrier panel.

Disclosed herein is a portable aerosol-protective apparatus and method for reducing the exposure of healthcare workers to contaminants and aerosols that may contain respiratory and other pathogens. The apparatus generally comprises a shield suitable for forming a partial enclosure around the head-space end of a hospital or surgery bed, through which a medical procedure can be performed on a patient. The method generally comprises performing the medical procedure on the patient through the shield of the disclosed apparatus.

A student enclosure assembly for protecting an individual from airborne pathogens includes an enclosure that is comprised of a fluid impermeable material to protect an occupant from pathogens. The enclosure has a plurality of air holes each extending through the enclosure to pass air into the enclosure. A plurality of filters is each integrated into the enclosure to filter pathogens from the air passing through the air holes. A pair of doors is each hingedly coupled to the enclosure for opening and closing the enclosure. A desk is positioned within the enclosure such that the desk is accessible to the user. A bench is positioned within the enclosure and the occupant can sit on the bench.

A personal exhaled air removal (PEAR) system for removing/evacuating exhaled air from a vicinity of a patient is designed to remove the exhaled air during an exhalation cycle of a patient. The system is synchronized with a patient's breathing cycle for activating suction of exhaled air via at least one suction inlet, and the suction inlet is adjacent to the patient, possibly attached to the patient via an interface.

The present invention provides devices and methods to capture airborne agents, microbes, including viruses, and microbial antigens, toxins and allergens and prevent the spread of infection from direct contact with contaminated surfaces (contact contamination), from large droplets of infectious material that fall out of the air, or from small droplets that can be carried by the air stream throughout the environment (airborne contamination).

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.

A testing system collects a specimen from a subject and measures the collected specimen to test the specimen, and includes a box to allow at least one of specimen collection for collecting and receiving the specimen, preprocessing for processing the collected specimen before measurement, or specimen measurement for measuring the preprocessed specimen to be performed therein.

An isolation chamber includes a plurality of walls and ceiling defining an internal chamber and a first and second door. The doors seal engagement with the walls. A fan filter unit is arranged to extract air from the internal chamber. The isolation chamber is arranged to couple to a doorway, and the coupling arranged to provide an airtight seal about the doorway.

An aerosol containment enclosure is used to isolate an air mass immediately surrounding a patient known or suspected to have a disease which may be transmitted through the air. The enclosure cooperates with a patient support apparatus (PSA). In embodiments, a flexible rod supports a substantially aerosol impermeable covering and is connected to the PSA. The enclosure may be semi-rigid and collapsible to a predetermined collapsed shape. The enclosure may be rapidly erected around a patient in an ambulance or other treatment setting. Embodiments of couplers provide compatibility with a wide diversity of sized and shaped PSAs. One coupler is connectable to the PSA with a coupler end exposed along a frame and upwardly extensible toward a PSA surface. A connector extends from the flexible rod and engages with the coupler end. The coupler may be longitudinally or laterally adjustable along the PSA.
