MORE THAN YOU EVER WANTED TO KNOW ABOUT SPUTUM!
I almost hesitate to write about this subject,
but I feel it must be included because it was such an integral part of the daily TB san experience as well as being one
of the most important indicators of our medical progress.
First, let's get the technical term defined. We all know what spit is, but the san patients
never used that term. We always referred to it as "sputum" because that's the medical term which was used
by all the doctors and nurses. The medical dictionary definition is:
Sputum:
Matter coughed up and usually ejected from the mouth, including saliva,
foreign material, and substances such as mucus or phlegm, from the respiratory tract.
Did you get that last part, from the respiratory
tract? This includes the lungs! And men with TB (and probably the women too) had plenty of
matter in their lungs to eject through their mouths. In fact, this activity was going on 24 hours a day. And no
matter where you were, the ward, locker room, solarium watching TV or sitting by your bed eating a meal, you never got away
from it.
But of course, this sputum contained active TB bacillus and was
infectious, so what do you do with it? The answer is the sputum had to be collected and destroyed. There
were two methods used to accomplish this. Each person had a sputum cup sitting on their nightstand at all times which
they used when they were in the vicinity of their bed. The elements of it are shown in the photos below.
It consisted of a metal cup, Photo 1, about 4 inches square, with a hinged lid and a finger tab to pop the
lid open. Inside the metal cup was a folded up disposable cardboard insert, which can be seen at the corners of the
cup, usually with cotton in the bottom to absorb the sputum.
The cardboard inserts with the sputum were collected everyday and destroyed. Photo 2 shows the flat
pattern for the cardboard insert with all its fold lines and the finished folded product.

But what if you were away from your bed? The metal sputum cup
was too big and awkward to carry around. Well then you used your handy smaller travel sputum box. It was made
from one piece of red cardboard material and it folded up into a slim container about the size of a pack of
cards which easily fit into your pajama top or bathrobe pocket. You carried it with you whenever you were
away from your bed. These were also collected everyday and destroyed.

Important Tests
But even thought it was pretty disgusting stuff, sputum had a redeeming quality. It,
along with x-rays, gave the patients one of the clearest indicators of their progress back to health. Once a month a
sputum sample was collected from each patient in a travel sputum box. They were sent to the lab and analyzed
to determine if the sputum was positive for the presence of TB bacillus. I forget the actual criteria, but I think
you had to have at least three consecutive non-positive sputum tests before you would even be considered for release
from the ward and put on meals. So your first negative sputum test was an important milestone. It meant you
might be making meals in just a matter of 2 or 3 months. At the san, 2 or 3 months seemed like a piece of cake!

On the right side of the Photo 5 are two rows of cardboard
travel sputum boxes each attached to a culture dish. The woman technician has an unfolded sputum box by her left
hand and is putting the contents into a culture dish. As far as I'm concerned, the only thing worse than listening to
all the coughing and spitting would be to work with the stuff in the sputum lab. My hat's off to the technicians for
all their work on our behalf
One final word before I close out this subject. Some of the men in my ward not only had
TB but also suffered from silicosis or "black lung" from their many years in the mines breathing in coal dust. Their
sputum was absolutely black and pretty much grossed out all the patients.
