Improvements in Pads for Medical or Surgical Bandages, and in
Means for Holding the same in Position.
A communication to me from Dr. GEORG HERRMANN, of Elsässerstrasse 71, Berlin,
in the Empire of Germany, Surgeon.
I, EDMUND EDWARDS, of the Firm of Edwards and Co., Chartered Patent
Agents and Engineers, of 65 and 66, Chancery Lane, in the County of Middlesex,
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, and accompanying drawings, that is to say:-
This invention has for its object more especially an improved method of con-
struction of the pads upon medical or surgical bandages, and it has great advan-
tage over such devices as heretofore ordinarily used, inasmuch as the position of
the pad can be easily and exactly adjusted in the desired position, in which it is
firmly and securely held.
In the accompanying drawings, which are in illustration of the invention,
applied by way of example to a menstrual pad or bandage.
Figure 1 is a longitudinal section.
Figure 2 a front view, and
Figure 3 a transverse section.
The invention consists essentially in making the pad a so that it can be fitted
upon an elastic tube b of air-tight material, such for instance as indiarubber,
in such manner that when the pad has been adjusted in the desired position,
the tube b can be inflated or blown out so that it can expand outside each end
of the pad, forming a swelling (as shown in Figure 1) by which the pad is firmly
held. These swellings absolutely prevent the shifting of the pad upon the tube.
The air forced into the tube is retained and prevented from escaping, by a
valve e in the air supply pipe d, or by a clamp or other equivalent means.
The
devices described are hollow or tubular, as clearly shown in the drawing.
The sides of the tubular pad thus formed may-as shown in section in Figures 3
and 5-be made in one part of a material absorbing fluid, and in the other part of
waterproof or non-absorbent material.
Figure 4 shows a pad, the sides of which are entirely of absorbent material,
and of equal thickness all round.
The absorbent material may be saturated more or less with antiseptic, aseptic,
deodorizing, astringent, or other suitable medical substances, and such sub-
stances may also be used upon the tube b.
in Figures 6 and 7 pouches e are shown, consisting of elastic material. These
pouches e are made of elastic material provided with slits through them as shown,
which when the tube b is inflated open or bulge by the expansion of the pouches,
as shown in Figure 7, and so allow the medicated or other substance to pass out.
Having now particularly described and ascertained the nature of the said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
1. The arrangement for holding pads firmly upon bandages, consisting of a

page_text: hollow or tubular pad fitting upon an elastic expansible tube, and prevented from
moving upon the tube by the swellings formed upon the latter when it is
inflated, substantially as described and illustrated.
2.In the pad described and claimed in Claim 1, the method of making the
sues of the latter partly or entirely of absorbent material, substantially as and for
the purpose described.
3. In apparatus of the kind described in Claim 1, pouches e of elastic material
arranged upon the elastic tube b, and provided with slits or openings, substan-
tially as and for the purpose described, and illustrated in Figures 6 and 7.
