ments in two minutes, thus greatly
lessening the time and labor cost.
Also he noted, when the same set of
surgical instruments is needed for
two consecutive operations, the
stepped-up cleaning process reduces
the time lapse between operations.
This makes possible more efficient use
of operating room facilities.
The machine at Duke not only
saves time and money, but gets in
struments cleaner than was formerly
possible with the best of conventional
methods, Dr. Hart stated.
He explained that the machine’s
action depends on high frequency
sound waves of 18,000 cycles per sec
ond striking the submicroscopic nu
clei or particles found in all liquids.
When one of these nuclei is struck by
a sound wave, it collapses inwardly
for a fraction of an instant. This
creates a vacuum in the pin point of
space formerly occupied by the nu
cleus.
The terrific pulling power of these
vacuums attacks caked blood and
other “protein soil” like countless
vacuum cleaners, working in joints
and crevices impossible to reach by
any other practical method.
After immersion in the ultrasonic
bath, the instruments are sprayed
with hot water to remove loosened
protein soil and then are dried by
warm air. Steam sterilization com
pletes the process of preparing the
instruments for operating room use
again.
Developed cooperatively by the
American Sterilizer Company and
Bendix Aviation Corporation, the
new machine represents the first ap
