COMPLETE SPECIFICATION.
An Improved Protecting and Disinfecting Case for Thermometers.
We GUSTAV OLLENDORFF Dr. Med. and OSKAR ROBERT FISCHER of
Barmen in the German Empire Rödigerstrasse 8 and Cleferstrasse 53 do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
The cases or etuis for medical thermometers hitherto used have only the purpose
to guard the thermometers and prevent them from being broken or otherwise
damaged.
Our invention has for its object an etui or case for medical thermometers serving
likewise for the named purpose but being generally destined to disinfect the
thermometer after use.
The manner in which we carry our invention into

effect is shown on the
Figure 2 a view of the
The new etui consists of two cylindrical or otherwise shaped parts a b, which
preferably may be screwed together.
The bottom part a is provided with a sockle d for placing the case upon a table,
at its top it is closed by a lid e through which is drilled a hole.
Now the lid is fitted with a layer of felt or any other material having the
quality of absorbing liquid readily, which is secured in its place by a hollow nut c.
The upper part 6 forins a tubular piece, it is closed at its top by a lid / and
connected with the lower part by being screwed over the nut c.
As will be seen from Figure 1 the part a is filled with any antiseptic liquid
which is best done when the nut c is unscrewed.
Into the liquid plunges the thermometer resting with its point upon a layer of
felt and being suitably guided by the layer so that it is easy to understand how
the thermometer will be perfectly disinfected and cleaned from any contagious
matter by the liquid. Therefore a cleaning by hand of the thermometer is
unnecessary and a danger of contagion which easily may happen with an uncleaned
thermometer perfectly avoided by our invention.
When the thermometer is drawn out of the etui by means of a little button
shown in dotted lines in Figure 1 it may be perfectly dried by the layer of felt so
that it is directly ready for use. The button may however be omitted and then
the upper part of the thermometer may be also inserted into the liquid and
disinfected.
For preventing any shifting of the thermometer in its case there are arranged
layers of felt g, fitted to the inner bottoms of the parts a and b respectively.
When screwing the part a and the nut c more or less together, the layer f works
like a stuffing box and does not allow the escape of liquid to the upper part and
the etui may then be put in a convenient position into a coat or waistcoat pocket.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
An etui for guarding and disinfecting purposes for medical thermometers

together, the lower part being filled with antiseptic liquid for disinfecting the
thermometer inserted into it and dried by a layer of felt or other liquid-absorbing
material, when drawn out of the case; the layer forming at the same time a
stuffing box, that prevents the escape of liquid to the upper part of the etui.
The whole as and for the purpose set forth.
