A reusable, elastomeric respirator and ventilator, with filter inserts, including a mask body having a pliant facial interface on the interior of the mask body, and two apertures centrally positioned on the front face of the mask body. Two interchangeable plugs or ports are provided to be received within and seal the apertures, deliver oxygen into the mask, or deliver liquids to a wearer of the mask. On opposing sides of the mask body are air filter housings which support an air filter, each air filter housing including a base support structure affixed to the mask body and a top securing structure removably secured to the base support structure. One or more straps are affixed to the mask body to secure the mask body about a wearer's head.

A medical fluid treatment system includes a source of purified water; at least one concentrate for mixing with the water from the source to form a treatment fluid; a disposable set including a pumping portion, a concentrate line in fluid communication with the concentrate source and the pumping portion, and a patient line in fluid communication with the pumping portion, the patient line including a filter having a membrane configured to filter the treatment fluid, the filter configured such that (i) fresh treatment fluid flowing from the pumping portion towards a patient flows through the membrane and (ii) used treatment fluid flowing through the filter from the patient to the pumping portion bypasses the membrane; and a medical fluid delivery machine including a pump actuator operable with the pumping portion of the disposable set.

A ventilator includes a bidirectional breath detection airline and a flow outlet airline. The flow outlet airline includes an airline outlet. The flow outlet airline is configured to be connected to an invasive ventilator circuit or a noninvasive ventilator circuit. The breath detection airline includes airline inlet. The airline inlet is separated from the airline outlet of the flow outlet airline. The ventilator further includes a pressure sensor in direct fluid communication with the breath detection airline. The pressure sensor is configured to measure breathing pressure from the user and generate sensor data indicative of breathing by the user. The ventilator further includes a controller in electronic communication with the pressure sensor. The controller is programmed to detect the breathing by the user based on the sensor data received from the pressure sensor.

An airborne pathogen extraction system that provides for continuous airborne pathogen particle extraction from a specifically targeted area in a room or a specifically targeted area proximate to a user. The pathogenic particles are filtered and/or disinfected before the air is returned proximate to the originating location, or are directed an area away from the user(s). The airborne pathogen extraction systems and methods lower the chances of contagion or infection from airborne pathogens, such as viruses.

A nasal device includes a tip member having a first end and a second end, the second end of the tip member being oppositely disposed relative to the first end, the tip member including a first wall disposed at the first end thereof, the first wall defining a first aperture configured to be in fluid communication with a nostril of a person; a cover member disposed over a portion of the tip member, the cover member including a second wall overlapping at least a portion of the first wall of the tip member, the second wall defining a second aperture configured to be in fluid communication with the nostril of the person and the first aperture of the tip member, the cover member configured to provide a seal with the nostril of the person; and a vacuum source or a fluid container coupled to the tip member.

Environmental characteristics of habitable environments (e.g., hotel or motel rooms, spas, resorts, cruise boat cabins, offices, hospitals and/or homes, apartments or residences) are controlled to eliminate, reduce or ameliorate adverse or harmful aspects and introduce, increase or enhance beneficial aspects in order to improve a “wellness” or sense of “wellbeing” provided via the environments. Control of intensity and wavelength distribution of passive and active Illumination addresses various issues, symptoms or syndromes, for instance to maintain a circadian rhythm or cycle, adjust for “jet lag” or season affective disorder, etc. Air quality and attributes are controlled. Scent(s) may be dispersed. Hypoallergenic items (e.g., bedding, linens) may be used. Water quality is controlled. Noise is reduced and sounds (e.g., masking, music, natural) may be provided. Passive and active pathogen controls are employed. Controls are provided for the occupant and/or facility personnel, as is instruction, and surveys, including assessing wellness.

Devices and methods for managing chest or wound drainage are disclosed where in one embodiment, the system generally comprises a chest tube configured for insertion at least partially within a body of a subject, a drainage tube fluidly coupled with the chest tube, a reservoir fluidly coupled with the drainage tube, a pump in communication with the reservoir, and a controller in fluid communication with the drainage tube. The controller may be configured to determine a readiness for removal of the chest tube from the body based upon one or more removal parameters which are obtained over a period of time via the controller.

A sedation device (1) has a housing (2) having a ventilator chamber (3) and an associated patient chamber (4) in communication with the ventilator chamber (3). A filter (5) is mounted between the ventilator chamber (3) and the patient chamber (4) and forms a common gas-permeable dividing wall between the ventilator chamber (3) and the patient chamber (4). An inlet port (6) is provided on the ventilator chamber (3) for connection via a Y-piece to a ventilator. An outlet port (9) of the patient chamber (4) connects via a patient breathing tube (10) with a patient. An associated pair of inserts are provided, namely a first insert (14) fixedly mounted in the ventilator chamber (3) and a second insert (15) fixedly mounted in the patient chamber (4). One or both of these inserts (14, 15) are mounted within the housing (2) to vary the internal volume of the housing (2) as required to suit different patients. The inserts (14, 15) are nestably engageable with an inner wall of the housing (2).

A method and system for separating a flow of matter is shown and described. The system includes one or more flow separation devices, one or more surgical instruments, and one or more suction sources. In some embodiments, the flow of matter comprises biological material. In some embodiments, the flow of matter comprises surgical waste.

A head encapsulation unit is disclosed which filters virus contaminated air. The head encapsulation unit does not require a fitting process since the primary interface between the head encapsulation unit and the user is the user's neck. The head encapsulation unit has an expandable seal that a user can insert his or her head. The seal is then wrapped around and places light pressure against the person's neck so that virus contaminated air that does not enter the inner volume of the head encapsulation unit and infect the user. A cap at the upper portion of the unit and the seal aligns the head encapsulation unit on the user's head. This head encapsulation unit allows for both medical personnel and infected individuals to better and more easily communicate than mouth covered filters, goggles and face shield while offering substantially more mitigation from spreading an infection or being infected.
