A medical cover is comprised of a stretchable ply which is effectively adhered, at least in part, to the patient during use of the cover. The cover comprises a cover body defining top and bottom edges and first and second side edges, an inflatable zone defined by said body and which is defined by a border, at least one inflation port in the inflatable zone, and at least one instrument access port through which surgical instruments can be passed. The inflation port is connectable to a source of a sterile pressurized lifting fluid or gas, such as air or nitrogen. In use, the medical cover forms a dome which defines an enclosed aseptic zone in which the atmosphere can be controlled.

A negative-pressure dome includes a transparent domed shield, a flexible skirt attached to the perimeter of the domed shield, a hose attachment port formed on the domed shield; and access openings in at least one of the domed shield and the flexible skirt. The transparent domed shield consists of a clear rigid plastic. The access openings may be at least partially occluded by flexible flaps that are deflectable to increase an open cross-section of the access openings. In a first configuration, the access openings are disposed in the domed shield sized to cover a face and are sized to have a cross-section between 3 cm.sup.2 and 200 cm.sup.2. In a second configuration, the access openings are disposed in the flexible skirt and are sized to have a cross-section between 30 cm.sup.2 and 200 cm.sup.2, while the domed shield is sized to cover head and chest of a subject.

A method for treating cancer is described using combination therapies comprising the use of hyperbaric oxygen with histone deacetylase inhibitors, with and without glycolytic therapies. The patient is subjected to a hyperbaric environment of substantially pure oxygen. A predetermined dose of one or more HDACI substances is administered to the patient. In addition, glycolitic inhibitors may also be administered. Dosages, pressures, and durations are selected as described herein to have a therapeutic effect on the patient.

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 protective equipment includes a rotatable window and an extended member secured to a peripheral edge of the rotatable window. The rotatable window may be configured as a shield to be disposed between a patient and a healthcare worker to minimize exposure of the healthcare worker to at least one of the patient's bodily fluids, bacteria, and viruses. A port provides entrance by one or more instruments through the rotatable window or the extended member, thereby providing access to the patient while protecting the healthcare worker from the patient's bodily fluids, bacteria and/or viruses. The protective equipment may include an air flow system configured to receive and filter air expelled by the patient, to pull the expelled air away from the patient's face and to filter/clean the expelled air.

A medical chair protective barrier and gas distribution system provides a frame that forms a sealed environment for a medical gas delivered to head of a dental chair. The frame fastens to the medical chair, or rolls to head of medical chair. A laminar flow subassembly secures to frame. The laminar flow subassembly includes a vacuum pump, tubing, positive and negative pressure ports, and a vent for delivering medical gas to the head of medical chair. The frame carries a hood that covers the head of medical chair. The hood retains medical gases in a sealed environment, while protecting dentist from contact with medical gases. The hood includes a window and a pair of arm passages that regulates access to inside of hood. Medical armamentarium hangs on frame for access. System has inlet and outlet vacuum ports that utilize HEPA filters and hidden UV lights for disinfecting under the hood.

A medial isolette is provided. A flexible enclosure and a collapsible wire-frame structure are provided which supply an economical and easily assembled isolation chamber. A flexible drape is provided to further isolate the patient and effectively control a negative pressure environment within the isolette. Access ports with integrated or removable gloves are provided to access the patient when the isolette is in use. A component access panel is provided for ducted connection of patient gas circuits and leads and source of negative pressure.

The present invention discloses an isolation system, comprising a flexible, portable, disposable membrane with no rigid structures. The membrane inflates from a contracted state having a small form-factor for storage to an inflated state for use. The membrane has an opening on one side defining a chamber within, with the opening having a sealing member that when closed, seals off the chamber. The membrane includes a first port for ingress of gas into the chamber a second port for egress of exhaust gas via an associated exhaust filter assembly, with the second port intrinsically functioning as a passive pressure regulator.
