"ALL THE BLOOD IN THE BODY CAN BE PUMPED
OUT AND CLEANED OF DISEASE GERMS"
Baltimore, Feb. 5. That all of a
human being's blood can- be pumped
out of the , arteries, cleaned and
pumped backTntothe body is claim-
Sketch of the marvelous artificial
kidney below Dr. Welch's picture
shows the 32 tubes in which the blood
is purified. . .
ed in an artificial, kidney: by learned
doctors of John Hopkins University.
Yet it's an experience that may
soon come tor all of us, with the per
fection of the marvelous new appara
tus which lias just been put out from
the pharmacological laboratory of
John Hopkins University under the
supervision of Dean William H.
Welch, and which will probably solve
some of the most vexing medical
problems of the day. Kidney diseases
are increasing with alarming rapidity.
It is thought that the John Hopkins
artificial kidney in many cases will be
successfully used to perform the
hlood purifying function in which .the
diseased natural kidney fails.
The apparatus consists of 32 tubes
contained in a glass case. The tubes,
made of a substance called celloidin,
are connected at one end with a sin
gle tube which may be attached to
an artery, and at the other, with a
tube which leads to a vein. Before
the artificial kidney is attached to the
body, the tubes are filled with a solu
tion of salt and water.
- When it is put in position, the heart
pumps the blood out from the artery
into the tubes and forces the salt
solution back into the veins to take
While in the tubes the blood is puri
fied of its poisonous substances by
dialysis a process by Tvhich harm
ful substances contained in the blood
seep through the delicate celloidin
walls of the tubes into a fluid which
is held in the outer space between the
tubes and the glass case. By chang
ing the composition of this fluid the
physician Can determine what sub
stances shall, pass into it by dialysis
of the blood.
This astounding machine has been
used with complete success on dogs
and other animals. The three physi
cians who made it, Dr. John J. Abel,
Dr. Leonard C. Rowntree and Dr. D.
B. Turner, are now elaborating an
artificial kidney which they expect
will be used on humans with perfect
safety, and will be invaluable for
cleansing impure blood.
