| 20080210234 | VARIABLE PRESSURE CHAMBER HAVING A SCREW COMPRESSOR - A variable pressure chamber is provided for operation at hypobaric or hyperbaric pressure. The variable pressure chamber comprises a substantially air-tight enclosure having a sufficient volume to enclose a patient, a sealable opening adapted to provide access to the enclosure, a closure mechanism adapted to seal the sealable opening, a reversible compressor fluidly connected to the enclosure and an outlet flow modulator. A method of treatment of a subject in need thereof using the variable pressure chamber is also provided. | 09-04-2008 |
| 20090120433 | Controller for an extremity hyperbaric device - 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. | 05-14-2009 |

| 20100018525 | Apparatus and method for increasing, monitoring, measuring, and controlling perspiratory water and solid loss at a reduced ambient pressure - A device for increasing, monitoring, and measuring perspiration water and solid loss at reduced ambient pressure, comprising a sealed chamber capable of maintaining less than atmospheric pressure for an extended period of time and a gasket-sealed door accessing the chamber. The chamber provides a controlled hypobaric environment for treatment of various medical conditions. Internal controls of ambient pressure inside, temperature, humidity, oxygen, CO2 and other environmental conditions within the chamber are included, as well as a mechanism for recovering perspiration water loss from an occupant of the chamber. Methods for determining the perspiration volume of water and solid loss experienced by an occupant in the chamber are also disclosed including a computer program for determining quantity of sweat produced by the occupant of the chamber on a continuous basis. An algorithm allowing for continuous calculations of sweat loss and fluid replacement requirements of the occupant of the chamber is disclosed. | 01-28-2010 |
| 20100037892 | INTERLOCK VESSEL FOR HYPERBARIC TRANSFER SYSTEM - An interlock vessel having an air-tight body with opposing ends. A portion of the body is designed to fit into a decompression (hyperbaric) chamber, wherein a diver or a patient undergoing a decompression treatment is positioned. The opposing ends are closed by pivotally moveable doors and locking assemblies that retain the doors in a closed position until the pressure inside the decompression chamber and the exterior of the chamber can be equalized. The outer door has two locking systems: (a) an interlock system and (b) a safety/delay locking system. Both locking assemblies are manually operated. | 02-18-2010 |
| 20110000484 | VASCULAR THERAPY USING NEGATIVE PRESSURE - System and methods for applying vascular therapy to a body vessel using a chamber capable of negative and/or positive pressure relative to ambient are provided. The chamber includes one or more pressure-isolated chambers. A pressure and/or vacuum source is connected to the pressure chamber, and is configured to provide distinct pressures within each pressure-isolated chamber. A controller is coupled to the pressure source, and is configured to control the pressure source such that pressure within each of the pressure-isolated chambers is controlled cyclically to simulate a pulsating pump or peristaltic-like pump action within the body vessel. The use of negative pressure is sequenced such that the resistance to pressure toward the heart is reduced. This effectively “pulls” blood flow toward the heart and creates more space for incoming blood flow. During simulation, medical devices may be introduced to and/or diagnostics may be performed on the targeted vessel. | 01-06-2011 |
| 20120266874 | HUMAN HEALING ABILITY ENHANCING APPARATUS AND METHOD FOR ACTUATING HUMAN HEALING ABILITY ENHANCING APPARATUS - A human healing ability enhancing apparatus includes an airtight part that is capable of being airtight; a decompression pump that decompresses air pressure in the airtight part and communicates with an exhaust port of the airtight part; and an over-decompression prevention device for preventing over-decompression in which the air pressure in the airtight part is lower than a predetermined threshold air pressure. The apparatus that can favorably provide a stimulus for enhancing healing capacity of a living body by a decompression control means sequentially and repeatedly controls a decompressing process in which air pressure in the airtight part that is capable of being airtight is changed to a decompression state that is equal to or higher than the threshold air pressure during 1 to 60 minute(s), and a pressurizing process in which the decompression state is changed to a wide-range normal pressure state that is a normal pressure or a pressure higher than the decompression state and lower than the normal pressure during 1 to 60 minute(s) can be obtained. | 10-25-2012 |
| 20140014100 | METHOD AND APPARATUS FOR CYCLIC VARIATIONS IN ALTITUDE CONDITIONING - A method and apparatus for cyclic variations in altitude condition that allows a user to rest in a pressure vessel while undergoing rapid variations or transitions between simulated altitudes. The pressure vessel comprises a blower to generate negative pressure, and a proportional valve to allow air back into the pressure vessel in order to relieve the negative pressure. An on-board interface, kiosk controller and master controller are all in electrical communication with each other in order to enable a user to implement a program of cyclic variations in altitude conditioning that is suitable to the specific user, and enables an operator to bill the user for such services, as well as to allow the user to use a different pressure vessel without re-entering data, so long as such data was originally entered and stored, and the different pressure vessel is in electrical communication with the master controller. A user sensor monitors the user during a session, such that the program may be modified or replaced with another program in real time, according to the user's needs. | 01-16-2014 |
