Abstract:

A pump augmentation uses a nozzle output which is controlled in pulses to produce vortex rings and is controlled such that where m=the total mass of fluid emitted during a single pulse of duration t, =the average density of the fluid emitted in the pulse. A=the cross-section area of the nozzle orifice (= /4Dfor a circular nozzle), D=the primary dimension of the nozzle orifice (=the exit diameter of the nozzle for circular nozzles), t=pulse duration, and U=average velocity of the fluid at the nozzle exit during one pulse (during t).

Abstract:

A pacifier comprising an endotracheal tube holding means for intubated infants. The pacifier further comprises a nipple member attached to a flange member, wherein a channel is disposed longitudinally along the nipple and flange to accommodate an endotracheal tube. A slot, smaller in circumference than the tube, is disposed along the channel and allows the tube to be inserted and removed from the pacifier. The channel is larger in circumference than the tube, so that once the tube is inserted into the pacifier, it is supported in the channel, but can move longitudinally through the channel relative to the pacifier.
