:
1, JOSEPH SEBASTIAN NEUMEYER, Doctor of Medicine, Pensioned Military
Physician in the Bavarian Army, of 36 Marsstrasse, Munich in the Kingdom of
Bavaria, Empire of Germany, do hereby declare the nature of this invention to:
be as follows:
:
The object of this invention is a regulation truss serving to check and repress
any abdominal injury, bubonocele or rupture in the thigh in its various positions'
and at the same time to completely prevent any recurring perilous moments, for
instance strangulation and symptoms of incarceration.
The improved device is made in the main as follows:
The metal plate of the cushion has an elliptic hand shape and is provided on one'
side with an extension adapted to bend itself down finger-fashion under the
horizontal pubic bone limb, which is by nature too narrow. Said extension is also
adapted, in a somewhat widened shape to keep back the crural or thigh hernia
and it is immediately adjoined by a more stuffed and somewhat widened end of
the thigh strap. The metal plate has provided therein a screw projecting with its head
outside the cushion and connected with a lever or bolt which has the said screw as
fulcrum. On'said lever or bolt a cubiform slide can be shifted forward and backward
to the end, where it is prevented from falling out by a thickening or projection of
the lever. By more or less tightening or loosening the screw a more or less strong
pressure can be produced on the cushion and thereby on the rupture opening after
previous reposition of the intestines, while the slide prevents the lever from
spontaneous descent and can also be utilised for increasing and concentrating the
pressure.
As may be seen from the above, the pressing action can in each 'particular case
be securely and easily regulated and transferred to the respective point by the
wearer of the truss. After regulating the pressure, the closing end of the body,
strap is guided over the lever or over the slide itself and fastened to one of the
most convenient buttons of the cushion as with other bandages.
The body strap is provided with a longitudinal pad displaceable on the whole
length thereof by means of two or more outside cross straps or eyes, through which
the body, strap is passed. Also two or more of these pads may be provided, which
must be thinly stuffed with soft material and serve to protect any irritated or sore
portions of the skin or to equalize natural unevennesses of the body.
'
:
In lieu of the single metal spring hitherto used, the improved regulation bandage
has three superposed metal springs, the middle one of which is not made from
steel but from another softer metal, for instance a zinc alloy. This arrangement
has for its purpose to compensate the changes of temperature and obviate a
breaking of the spring by rust or long use.

An Improved Truss or Bandage for Abdominal Injuries.
1, JOSEPH SEBASTIAN NEUMEYER, Doctor of Medicine, Pensioned Military
Physician in the Bavarian Army, of Fürstenstrasse 22 Munich, in the Kingdom
of Bavaria, 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 object of this invention is a regulation truss serving to check and repress
any abdominal injury, bubonocele or rupture in the thigh, in its various positions
and at the same time to completely prevent for the future the perilous moments
frequently occurring with such injuries, for instance strangulation and symptoms
of incarceration.
Referring to the accompanying drawing,
Fig. 1 shows the truss placed upon the front side of the body with the screw
bolt on the cushion, over which bolt the body strap of the truss extends at its
closing end as illustrated in Fig. 2.
Fig. 2 shows the front view of the cushion and a view of the whole truss with
the other particulars.
Fig. 3 is a view of the metal plate of the same cushion of more oblong elliptic
hand shape, with its extension in, which bends itself down finger fashion under the
horizontal pubic bone limb too narrow by nature and is adapted in somewhat
widened shape to also keep back the crural or thigh hernia.
To the same
extension m Fig. 2 is directly joined the end of the so-called thigh strap n, the
latter being made slightly wider and with more stuffing at this end.
Fig. 4 is a longitudinal section of the cushion. In the metal plate of the latter.
is provided a screw c which is connected with a lever or bolt having said screw as
fulcrum. On this bolt a cubiform slide s can be shifted forward and backward
to the end, where it is prevented from falling out by a slight thickening or
projection.
P
By tightening or loosening the screw to the extent of about 1 to 2 centi-
metres, a slight or increased pressure can be produced on the cushion and thereby
on the rupture opening after previous precise reposition of the protruding intestines.
The pressing effect and its application to the proper place is therefore in the hand
of the afflicted person. Moreover the metal slide s, the lower half of which is
somewhat thickened, prevents any spontaneous descent of the lever and can be
utilized for increasing and concentrating the pressure.
By the lever bolt therefore any pressure on all points or every point of the
cushion surface is rendered transferable to its periphery and to each of its radial
extensions, as is approximately indicated by the dotted circles and radii in Fig. 2,
so that according to the various situations of the respective rupture openings and
to the various ages (moments to which of course also the shape of the cushion and
the size and strength of the other parts can be conformed) any protrusion of intestines
can be lastingly obviated, as especially the pressing action, which is of the highest
importance, can be in each particular case securely and easily regulated and
transferred to the respective point by the wearer of the truss by the above new
mechanical means of connecting the screw with the lever.
*.
These are advantages which certainly cannot be attained by merely providing
a number of intermediate buttons on the cushion plate, or by spring devices or such
like on the latter. The afflicted person, after reposition, need only turn the screw
head on the sinking or ascent of the same and subsequently guide the bolt (lever b)
to the rupture opening.
These pressing actions are identical with what the sufferer sometimes attempts
to effect with short finger pressure at the respective place for the retention of his
injury. To make surer of the pressure, he also shifts the metal slides to that

page_text: place and subsequently guides, along the latter over the lever or over the slide
itself, the closing end a Fig. 2, which he ultimately fastens to one of the most
convenient buttons of the cushion as with other bandages.
"",
The body strap is likewise provided with a longitudinal pad displaceable on the
whole length thereof. The outside of such a pad (about 12 centimetres in length
and 4 centimetres in width) is fitted with the two strips or bands i within which
the body strap can be moved. The inside of this side pad which is destined to
protect the attacked irritated and frequently sore skin of the sufferer, is made
smooth for this reason. The whole slide pad, several of which may also be
employed, must however not be worked in stiff material; it must be thinly stuffed
with wadding or similar soft material, not with horsehair or the like. Such a
displaceable pad also serves for equalising many a natural flattening and hollowing
in the circumference of the body over which the body strap extends.
As mentioned above, Fig. 3 shows the shape of the metal plate of an average
cushion of the bandage. Corresponding to the habit of a person having suffered
for some time from abdominal rupture, to instinctively and momentaneously place
his hand, in case of any protrusion, with his fingers kept together and with the
respective hand surface in a certain position on the injured part in order to effect &
retention, also the shape of the improved metal cushion plate differs from those
hitherto used and has accordingly (and with it the whole stuffed cushion) a more
elliptically oblong hand-shaped form, it appears more bent down and is moreover
provided below with a finger-elongation m, which shifts itself under the pubic bone
limb too narrow by nature and is particularly serviceable for crural hernia. A
continuation of this metal elongation m is formed as last closing means by the
soft no more metallic-wider continuation n of the thigh strap Fig. 2.
Every rupture aperture continues in a passage of more or less inclined shape up
to the cavity of the abdomen, as in the thigh ring which is frequently drawn out
long and inclined and likewise the thigh passage is in most cases longitudinally
and crosswise distorted. The purpose of a cushion for the respective injury should
naturally be to have a closing effect in the said directions; said cushion must
therefore develop, in becoming gradually broader, from the narrower body ring
(body bandage) acting as belt cover.
.
The improved regulation bandage has furthermore, as indicated by a Fig. 2, in
lieu of the single metal spring hitherto used, a compensation spring consisting of
three superposed springs, the outer two of which are of steel and secured to the
one end of the plate. The middle spring is made from zinc-or aluminium alloy
or the like and lies loose, between the two steel springs. This soft spring is
connected with the outer spring by two short pins provided at its ends and having
flat heads, said pins moving in small slots of the outer steel spring. With the
inner steel spring next to the body, the soft spring has no connection whatever,
but it lies loose thereon. The two steel springs are equal in length and width,
while the middle or soft spring is slightly narrower and shorter. The fastening of
the springs to the belt is effected as hitherto by leather lining.
The above arrangement has for its purpose to compensate the changes of
temperature in a similar manner as with the chronometer pendulum, as for
instance, when merely going out of the house, the body and bandage undergoes a
change of temperature. On the other hand also a breaking of the spring, which
might occur by rust or long use, is obviated by the improved arrangement.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
A. bandage or truss for abdominal injuries, in which :*
1) A revoluble lever b vertically adjustable by means of a screw and provided with
a slide s is arranged for the regulation of pressure and transmission thereof to any

page_text: :
2) The cushion is made in the shape of the human hand and the cushion plater
receives an elongation m, which is adjoined by a smaller softer extension'n forming
the slightly broadened end of the shank strap;
3) The metal spring of the body strap is made from metal layers or springs for
the purpose of compensating the changes of temperature, the whole substantially.
as illustrated and described.
