128205280 | Carbon dioxide | 13 |
20080196726 | APPARATUS FOR HYPOXIC TRAINING AND THERAPY - Breathing equipment to mimic the training of athletes at high altitude comprises a mouthpiece connected to a chamber containing a carbon dioxide absorber which is connected to the atmosphere by a tube. In use the air breathed out passes through the carbon dioxide absorber into the conduit where it mixes with atmospheric air and the mixture re-breathed. | 08-21-2008 |
20080276941 | APPARATUS FOR DELIVERING AND/OR SCAVENGING GAS IN THE NOSE/MOUTH AREA OF A PATIENT - Apparatus for delivering and scavenging anesthesia gas for a patient. A lower elongate piece forming a nose cannula for delivering gas, is removably secured generally parallel and immediately adjacent to an upper elongate piece for scavenging gas. The upper piece extends over a lower portion of the patient's nose, and has a plurality of openings disposed on a lower surface thereof, directed downward towards the patient's mouth. Both ends of the lower and upper pieces are provided with barbs for receiving corresponding supply and exhaust hoses at one end. Barbs at the other end are sealed by an end cap. A strap secures the apparatus on the patient's head. Thus the apparatus can be advantageously used with hoses on only one side of the face, thereby allowing the user to work with minimal obstruction on the opposite side of the face. | 11-13-2008 |
20080276942 | Re-Breather Apparatus With Vaned Filtering Canister - A breathing apparatus having a source of oxygen and a mouthpiece, which includes an inlet connected through a first one-way valve to receive inhaled gas, and an outlet having a second one-way valve to expel exhaled gas from a user. A scrubber canister is coupled to the mouthpiece and receives the output of the mouthpiece through the second one-way valve. The scrubber canister removes at least a portion of carbon dioxide from the exhaled gas from the user, and outputs carbon dioxide depleted gas. The scrubber canister has an inner canister and an outer canister and a plurality of vanes disposed between the inner canister and the outer canister. The vanes increase the dwell time of gas in the canister, thereby increasing the amount of carbon dioxide removed from the gas. Such construction can be implemented in rebreathers having radial, axial or cross-flow designs. | 11-13-2008 |
20080295844 | CARBON DIOXIDE ABSORBER FOR A REBREATHING SYSTEM - A carbon dioxide absorber for a rebreathing system can be connected to a connection head of the rebreathing system in a simple manner. A centering device ( | 12-04-2008 |
20090032023 | CLOSED REVERSIBLE BREATHING APPARATUS HAVING A METAL ORGANIC FRAMEWORK - The present invention relates to methods for removing carbon dioxide and, if appropriate, water from breathing air in closed or partially closed systems using a porous metal-organic framework material, such systems having at least one breathing apparatus and also their use and methods for regenerating the porous metal-organic framework material. | 02-05-2009 |
20090056720 | Apparatus for Installing or Uninstalling Carbon Dioxide Absorbent Canister - Disclosed is an apparatus for installing a carbon dioxide absorbent canister which comprises a body, a lifting member, and a lifting mechanism. The body comprises a breathing circuit and an adapter for connecting the carbon dioxide absorbent canister with the breathing circuit. The adapter is located at or near the bottom of the body. The lifting member comprises a base portion, a positioning portion beneath the adapter, and a connecting portion. The lifting mechanism has a force receiving portion and a force, applying portion and which actuates the lifting member. Actuating the handle in the first direction causes the canister to be connected to the breathing circuit and to close the breathing circuit bypass. Turning the handle in a second direction actuates the canister to enable replacement of the canister and to cause the breathing bypass to open. The process can be achieved simply with one hand. | 03-05-2009 |
20090107505 | DISPOSABLE ABSORBER WITH ADAPTER AND LIP SEAL - An adapter is provided for adapting an absorber container ( | 04-30-2009 |
20090120440 | RESPIRATORY CIRCUITS - A cartridge ( | 05-14-2009 |
20100199993 | DEVICE FOR SEPARATING MOISTURE FROM BREATHING GAS | 08-12-2010 |
20110277768 | Emergency Breathing Apparatus - Breathing apparatuses which utilize active scrubbing in a closed loop system providing for scrubbing of air on exhalation, but inhalation to be from a clean air source without the air from that source passing back through an active filter immediately prior to inhalation. The systems and methods may also use endothermic reactions from repressurization of make-up air to cool the clean air source providing further comfort. | 11-17-2011 |
20120325220 | HOUSING AND HOUSING ASSEMBLY FOR SUBSTANCE REMOVING AN UNDESIRED RESPIRATORY GAS COMPONENT OF A RESPIRATORY GAS FLOW AND AN ARRANGEMENT FOR VENTILATING LUNGS OF A SUBJECT - A housing for a substance removing an undesired component of a respiratory gas is disclosed herein. The housing includes a first space for the substance and a first wall surrounding part of the first space. The housing also includes a first end, surrounding part of the first space, comprising a first opening for the gas communication with the first space, and a second end, surrounding part of the first space, comprising a second opening for the gas communication with the first space. The housing further includes a first channel between the first and the second end for the gas flow, the first channel comprising a first orifice at the first end and a second orifice at the second end. The first orifice, the first opening, the second orifice and the second opening are in flow communication with outside the housing. | 12-27-2012 |
20130284179 | REMOVAL OF CARBON DIOXIDE FROM PATIENT EXPIRED GAS DURING ANESTHESIA - An assembly ( | 10-31-2013 |
20140283839 | ADVANCED SUPPORTED LIQUID MEMBRANES FOR CARBON DIOXIDE CONTROL IN EXTRAVEHICULAR ACTIVITY APPLICATIONS - There is disclosed a portable life support system with a component for removal of at least one selected gas. In an embodiment, the system includes a supported liquid membrane having a first side and a second side in opposition to one another, the first side configured for disposition toward an astronaut and the second side configured for disposition toward a vacuum atmosphere. The system further includes an ionic liquid disposed between the first side and the second side of the supported liquid membrane, the ionic liquid configured for removal of at least one selected gas from a region housing the astronaut adjacent the first side of the supported liquid membrane to the vacuum atmosphere adjacent the second side of the supported liquid membrane. Other embodiments are also disclosed. | 09-25-2014 |
