摘要： A system utilizes an oxygenation device to generate a gas-enriched physiologic fluid and to combine it with a bodily fluid to create a gas-enriched bodily fluid. The oxygenation device may take the form of a disposable cartridge, which is placed within an enclosure. An electronic controller manages various aspects of the system, such as the production of gas-enriched fluids, flow rates, bubble detection, and automatic operation and shut down.

摘要： A bubble detector utilizes an ultrasonic transducer to sample bubbles as they pass the transducer. The envelope of the return signal is analyzed to determine the volume of each sampled bubble. If the total volume of bubbles sampled within a certain period of time exceeds a desired maximum volume, the bubble detector may initiate a system shut down. A bubble detector can be evaluated or calibrated by introducing bubbles into a conduit, detecting the bubbles introduced into the conduit using visual inspection or a bubble detector of known resolution and comparing the results with the examination of a bubble detector under evaluation.
