Abstract: The ozone spray wand is a portable aqueous ozone generator that is adaptable to fit onto garden hoses, backpack sprayers or any other water supply source. The wand uses electrolytic cells to make ozone on-demand. An operator simply pulls the trigger and a solenoid valve starts delivering ozonated water. Embodiments use a rechargeable battery that allows it to operate for 1 hour between recharge cycles. The wand is rated for 500 hours of use which delivers 15,000 gallons of ozonated water.

Abstract: Illustrative embodiments employ catholyte scrubbers to provide higher concentrations of ozone in ozonated water than was possible in prior art systems and methods. Moreover, some embodiments employ scrubbers to increase the efficiency of production of ozonated water by producing such higher concentrations of ozone in ozonated water using the same amount, or less, power than prior art systems and methods. Some embodiments employ scrubbers to enable production of water with higher concentrations of ozone, and/or ozonated water in which the concentration of ozone decays more slowly, as compared to prior art methods.

Abstract: A solenoid operated drive system or actuating unit for driving blood pumps such as intra-arterial "balloon" pumps, implantable pulsatile pumps, external pumps and the like, wherein a shaft attached to the movable end of a bellows is caused to move back and forth by a pair of oppositely disposed solenoids. The extent of the excursion of the shaft and hence the movable end of the bellows is variably controlled by a first stopper fixedly attached to the frame and a second stopper fixedly attached to a carriage which is adjustably carried within the frame. The solenoids are alternately actuated and/or controlled by suitable control signals which are keyed to the heartbeat or R wave. At the beginning of each cycle for each solenoid and for a short time thereafter, depending on the cycle, a voltage is applied to provide maximum drive.

Abstract: A cardiac output monitor. The monitor receives signals representing radial arterial pressure, balloon pressure, balloon drive and balloon volume from an intra-aortic balloon pumping system. These signals are processed to define balloon depletion pressure (P.sub.1), ventricle ejection pressure (P.sub.2), balloon volume (BV) and heart rate (HR). The monitor displays the cardiac output according toCardiac output = (P.sub.2 /P.sub.1) (BV) (HR)the monitor also indicates certain improper pumping system operations and can provide a continuous display.
