Embodiments relate to systems and methods for delivery of oxygen or other treatment gases to a patient without requiring physical contact or enclosure of the patient. Embodiments can include a delivery hood, sensing components, and a gas distribution system including one or more gas delivery ports. Gas delivery ports may be individually controlled based on input from the sensing components to alter the volume and orientation of treatment gas flow directed at a patient. Sensing components can include cameras or other sensors that detect the position of a patient's head, and gas delivery ports may then be controlled to direct treatment gas flow in the direction of the patient's head. Embodiments and methods described thereby allow for efficient oxygen or other gas delivery to a patient without requiring contact or enclosure of the patient.

An apparatus and method for blood oxygenation are provided. The apparatus includes a chamber having a first inlet to receive a gas-supersaturating fluid, e.g., physiologic saline; a second inlet to receive a gas, e.g., oxygen, from a gas supply; and an outlet coupled to a capillary assembly. An atomizer nozzle coupled to the first inlet creates within the chamber fine droplets of fluid into which the gas diffuses to create the gas-supersaturated fluid, which is removed via the outlet. The removed gas-supersaturated fluid mixes with blood within a liquid-to-liquid oxygenation assembly to form oxygenated blood for delivery to a patient. Alternately, the blood may be provided by the pump to a high pressure hollow fiber or other type membrane oxygenator within which oxygen diffuses across the membranes(s) and into the blood to form oxygenated blood, again for delivery to a patient or other site.

The invention provides an ultra high-speed preparation method and a device for tea making water. The method comprises the steps of: setting flow and each-stage electric power; dividing a water body heating curve of a pipeline heater into a quickly-heated linear region and a slowly-heated nonlinear region; leading the pipeline heater to work in the controllable nonlinear region and keep away from the linear region by a master control board; heating up the water which is fed into the pipeline heater; obtaining the water with a target water temperature from a water outlet; installing an outlet water temperature sensor at the water outlet; computing, tracking and compensating the water temperature decrease caused by the characteristic drift and the air injection since the pipeline heater works for a long time by the master control board; automatically adjusting the electric power by a heating body sensor according to the heating curve when the water is heated up; and precisely controllingthe water temperature at the water outlet at + / -2 DEG C. After the tea making water is prepared by the method and the device, and the phenomena that the temperature rise is too fast, the water is highly burnt, and the water cluster is broken caused by the hysteretic response speed of the heating body sensor are thoroughly eradicated, so that the water can be used for making the tea which is mellow, fragrant, sweet and good in aroma and taste, and therefore, the device is a substitute for upgrading and updating the existing water dispenser.

The copper-based powder prepared by using the method of the invention has the advantages of low oxygen content, low apparent density and good metallurgical properties.

A method is disclosed for determining analyte concentration that includes applying a first electrical potential excitation pulse to a body fluid sample in an analyte sensor, and a first current response of the body fluid sample to the first pulse is measured. A second excitation pulse is applied to the body fluid sample in the analyte sensor, and a second current response of the body fluid sample to the second pulse is measured. An analyte level in the body fluid sample is determined by compensating for sources of error based on the first current response to the first pulse.

A skin dressing comprises a first dressing component (16) carrying oxidoreductase enzyme in dried condition; and a second dressing component (18) carrying a source of water, such that when the first and second dressing components are placed in fluid communication with each other, water migrates from the second component towards the first comportent and acts to hydrate enzyme carried by the first component, at least at the surface of the first component. The dressing components are kept separate before use, e.g. being sealed in separate sterile, water-impervious packages such as laminated aluminum foil pouches. In use of the dressing, the second dressing component is located on the skin of a human or animal, e.g. over a wound to be treated or on a region of skin to be treated for cosmetic or therapeutic purposes such as for treatment of acne or other skin conditions. The first dressing component is placed on top of the second component in fluid communication therewith. In embodiments comprising only first and second dressing components, the first dressing component is placed in direct contact with the second dressing component. Water from the second component migrates towards the first comportent and acts to hydrate enzyme carried by the first component, at least at points of contact at the interface between the first and second components. Once hydrated, the oxidoreductase enzyme can immediately begin functioning in known manner with beneficial effects.
