A controller is operable to selectively supply gas to, and evacuate gas from, regions of a hyperbaric wound treatment chamber. The controller operates to inflate a passage or rib of the device to provide that the device is made sufficiently rigid for inserting a limb therethrough, and inflate an inflatable cuff to create a seal against the limb. The controller also operates to evacuate ambient air trapped within the chamber, and optionally partially evacuate the passage or rib, after the seal is created by the inflatable cuff, and then introduce oxygen into the chamber, and optionally inflate the passage or rib. The cuff, when inflated and creating a seal against a limb, optionally is at least partially within the chamber, and the treatment gas is supplied to the chamber to maintain the seal of the cuff against the limb.

An air conditioning assembly for an environmental chamber includes an air handling unit for supplying air to the environmental chamber. A plurality of ducts in fluid communication with the air handing unit and in fluid communication with the environmental chamber are configured to draw air from one side of the environmental chamber through at least one outlet vent, and to blow air into an opposite side of the environmental chamber through at least one equal but opposite inlet vent. At least one air conditioning means in fluid communication with the at least one air handling unit is configured to condition the air flow passing through the air handling unit. The at least one air conditioning means includes an altitude simulator for changing the oxygen content of the air flow. In use, the air conditioning assembly is configured to create substantially laminar air flow throughout the environmental chamber.

A collapsible air isolation apparatus is disclosed. The apparatus may include a collapsible frame including a base and a set of rigid panel elements at least partially enclosing a volume of space, where the set of rigid panel elements is foldably hinged to at least one of the base or another of the rigid panel elements, and where at least one panel of the set of rigid panel elements comprises an open space for mounting a motor for moving air. The apparatus may include the motor for moving air configured to create a negative pressure within the volume of space of the collapsible frame.

A sterile environment system can include an enclosure and a support system. The enclosure can include a barrier separating a sterile environment inside of the enclosure from a non-sterile environment outside of the enclosure. The barrier can include an expandable portion configured to expand from an unexpanded state to an expanded state for working within the sterile environment, and a patient-interfacing portion including a fenestration configured for placement directly over an area of interest of a patient, the fenestration having a sealed state and an unsealed state for access to the area of interest from within the sterile environment. The support system can be coupled to the patient-interfacing portion of the barrier such that it is positioned on at least opposite sides of the fenestration.

An eyesight improvement method operable to reduce or eliminate the effects of eye disease such as but not limited to presbyopia wherein the present invention deploys utilization of a hyperbaric chamber. The present invention includes utilization of a hyperbaric chamber wherein the participant in the method of the present invention will engage in a consecutive quantity of treatment sessions to be executed during a prescribed treatment term. The treatment sessions can range from fifteen to one hundred and fifty minutes with a preferred embodiment time of ninety minutes. The pressure within the hyperbaric chamber is set at a range of one and a half to two and a half atmospheric pressure with a preferred pressure at two atmospheric pressure. The preferred embodiment includes a treatment term of three months with a range being between one and five months.

Disclosed are enclosures for establishing a sterile environment over a patient for a medical procedure, as well as systems and methods thereof. An enclosure can include an expandable portion of a barrier separating a sterile environment inside of the enclosure from a non-sterile environment outside of the enclosure and a patient-interfacing portion of the barrier. The enclosure can also include a support system coupled to the patient-interfacing portion of the barrier in some embodiments. The patient-interfacing portion of the barrier can include one or more fenestrations for placement directly over one or more areas of interest of the patient, as well as for access to the areas of interest from within the sterile environment. When present, the support system can flank the fenestration. The support system is configured to support the enclosure on a surface when placed over an appendage of the patient or a main body of the patient.

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.

A controller is operable to selectively supply gas to, and evacuate gas from, regions of a hyperbaric wound treatment chamber. The controller operates to inflate a passage or rib of the device to provide that the device is made sufficiently rigid for inserting a limb therethrough, and inflate an inflatable cuff to create a seal against the limb. The controller also operates to evacuate ambient air trapped within the chamber, and optionally partially evacuate the passage or rib, after the seal is created by the inflatable cuff, and then introduce oxygen into the chamber, and optionally inflate the passage or rib. The cuff, when inflated and creating a seal against a limb, optionally is at least partially within the chamber, and the treatment gas is supplied to the chamber to maintain the seal of the cuff against the limb.

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.

Methods and devices are presented for the long-term treatment of a patient infectious with deadly microbes without a risk for spread of germs to caregivers comprising a hermetically sealed human sized containment box with means for delivering medical care, for sustaining life, and for dealing with waste products, as well as providing rehabilitative care.
