摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for forming a portable liquid oxygen using an oxygen concentrator for patients having respiratory diseases. SOLUTION: The excess capacity gas flow from a gas concentrator (11) is split off and then stored in a storage dewar (14) via liquefaction. The stored gas can be used as a portable supply. A portion of the oxygen gas flow generated by the oxygen concentrator is channeled to a condenser (13). The condenser receives and liquefies the oxygen gas using cryocooler (12). The storage dewar (14) is used for storing the oxygen liquefied by the condenser. A liquid is then selectively transferred to a smaller portable dewar (23). A controller can be used for monitoring the parameters of liquefaction (including oxygen concentration, the amount of liquid oxygen in the dewar), and for controlling the parameters of liquid oxygen generation and transfer.

摘要： A rotary valve (21) at the inlets of a plurality of columns (18) cyclically selects first columns on a cyclic basis to receive compressed air, adsorb nitrogen and other components in the compressed air and pass oxygen and argon to a user (e.g. patient), second columns to desorb the adsorbed components in such columns and third columns to equalize pressures where the first columns change progressively to the second columns and vice-versa. A compressor (13) having adjustable characteristics and regulated in an open or closed loop introduces the compressed air through the valve to the first columns to provide an adjustable air flow for obtaining a prescribed oxygen flow to the user. An indication (88) may be provided when the compressor characteristics regulated for obtaining the prescribed oxygen flow rate are outside particular limits. The valve may have a variable speed related to the compressor flow variations to regulate the air pressure in the columns in accordance with the air flow rate into the columns. A variable orifice (27) in a valve in each column outlet becomes constricted with decrease in the oxygen flow rate in each column, thereby further regulating the oxygen pressure in such column. A porous plug in a closed chamber receiving the desorbed pressurized components releases such components slowly, without pulsatile noise, to the atmosphere. The equipment accordingly produces the desired oxygen flow rate with minimal power consumption, minimal noise and optimal efficiency, reliability and life span. The equipment may be designed to pass other components than oxygen.

摘要： The present invention is directed to a much safer and less expensive way of providing portable oxygen from a gas concentrator for patients who do not want to be tied to a stationary machine or restricted by present oxygen technology. The present invention involves a home liquid oxygen ambulatory system for supplying a portable supply of oxygen, where a portion of the gaseous oxygen output obtained from an oxygen concentrator is condensed into liquid oxygen. The system includes an oxygen concentrator which separates oxygen gas from the ambient air, a condenser in communication with the oxygen concentrator for receiving and liquefying the oxygen gas flow, a cryocooler associated with the condenser, and a first storage dewar in fluid communication with the condenser and adapted to store the oxygen liquefied by the condenser, the first storage dewar including means for transferring liquid oxygen from the first dewar to a second dewar for storing a quantity of oxygen suitable for moveable oxygen treatment.

摘要： PROBLEM TO BE SOLVED: To provide an improved apparatus to refine a fluid product by removing a specific component or a pollutant in a fluid mixture from a unified fluid source. SOLUTION: The apparatus to divide the fluid mixture like air by pressure swing molecular adsorption is equipped with the rotating divider valve 10 and the array of the adsorber column 22. The column 22 is held in the product holding tank 9 for one example, or attached to the product tank 130 for another example. As an adsorption/desorption cycle is optimized by the valve 10 which supplies a quasi-steady flow in the order, plenty of valves, switches and pipings usually required are omitted.
