A supply arrangement (100) and a process supply a medical device (50, 90) with a supply gas mixture. The supply gas mixture includes a carrier gas and an anesthetic and is generated by an anesthetic dispenser (3). A carrier gas mixing unit (9) generates the carrier gas from at least two carrier gas components. A carrier gas switch having a regular outlet and a discharge outlet selectively directs carrier gas components to the carrier gas mixing unit or to a discharge line (35). A gas mixture switch (6), having a regular outlet (41) and a discharge outlet (42) selectively directs the supply gas mixture to the medical device or to the discharge line (35). An anesthetic concentration sensor (5.1, 5.2) measures a concentration of anesthetic in the generated gas mixture. A control unit (2) controls the gas mixture switch based on measured concentration within or outside a predefined range.

Systems, methods and apparatuses for aerosolizing all or substantially all plant matter, medications, flavors, smells, liquid and/or other material to be aerosolizing are disclosed. Embodiments of the invention comprise an aerosolization chamber sealed except for two or more conduits, a first conduit coupled to a source of fully or almost fully oxygenated gas, a heating element capable of heating the aerosolization chamber to a temperature above a combustion temperature, a second conduit configured to transport aerosolized gases and elements out of the chamber and, in one implementation, at least one valve positioned in the second conduit preventing the flow of atmospheric air into the vaporization chamber. In some instances, the first gas substantially clears the vaporization chamber of atmospheric air prior to reaching combustion temperature. A second gas containing oxygen may be intermixed with the vaporization gases and vaporized elements proximal to the combustion chamber.

The invention relates to the field of medicine, and more particularly to emergency medical assistance. A respiratory intervention is performed on a patient with an artificial gas-air mixture having an increased content of argon of at least 30 vol %, enabling this artificial gas-air mixture to be effective continuously throughout the procedure. Furthermore, the respiratory gaseous medium has an increased content of oxygen with xenon being added and has the following composition: 1-10 vol % of xenon; 30-35 vol % of argon; 60-65 vol % of oxygen. The intervention on the patient with the artificial gas-air mixture of the composition mentioned is performed for 20-40 minutes or more, until specialized medical assistance is given. The method makes it possible to increase the effectiveness, safety and rapidity of relieving acute cerebral and cardiac ischemia, and to reduce the risk of developing an acute cerebral stroke or myocardial infarction.

A device for delivering a predetermined amount of at least one substance to a body orifice of a subject includes a) a container for containing said at least one substance; b) a delivery end for placement in proximity to the orifice, the delivery end being in fluid communication with the container; c) a valve mechanically connectable to said container, characterized by at least two configurations: (i) an ACTIVE CONFIGURATION in which said valve enables delivery of predetermined amount of said substance from said container to said body orifice via said delivery end; and, (ii) an INACTIVE CONFIGURATION, in which said valve prevents delivery of said predetermined amount of said substance from said container to said body orifice; d) a trigger mechanism adapted to reconfigure said valve from said INACTIVE CONFIGURATION to said ACTIVE CONFIGURATION, and vice versa; and e) a fluid tight chamber.

A device that can be used to store blood product and/or cellular culture that may or may not be under pressure. The device includes a chamber that can be hermetically sealed and a flexible secondary bag which can be placed in the chamber. The chamber is designed to receive at least one secondary bag that contains a conventional storage bag containing blood product and/or cellular culture. The storage conditions are created in the chamber and may or may not include 1) creating a pressure higher than atmospheric pressure, 2) creating a refrigerated temperature, and/or 3) providing agitation to the secondary bag. The secondary bag is filled with a gas system that is used to facilitate in the storage of the blood product and/or cellular culture. The secondary bag can be made of a material and/or include a coating or film that is impermeable to the gas system and to the gas inside the chamber. The higher-than-atmospheric pressure inside the chamber can be created by pumping an inexpensive gas, for example, air, into the chamber. The gas used to pressurize the chamber can be different from the gas system in the secondary bag.

Devices and methods for delivering oxygen and other therapeutic gases to a target, such as a tissue, a tissue-engineered construct, and a wound, in a controlled and sustained manner are disclosed.

The present disclosure provides for a control system for a flow therapy apparatus. The control system can control delivery of a fraction of delivered oxygen (FdO2) to a patient. The control system can maintain the FdO2 at a target level during a therapy session. The control system can automatically control an oxygen inlet valve in order to control the flow of oxygen to the patient.

Disclosed are the unique and unexpected findings that xenon gas possesses the ability to directly inhibited amyloid beta associated toxicity, inhibit production of amyloid beta, and stimulate synthesis of soluble, free-form amyloid beta. The invention teaches the use of xenon gas, as well as various combinations of Noble Gases, for the prevention, amelioration, and treatment of Alzheimer's Disease and other pathologies associated with generation of insoluble aggregates containing amyloid beta.
