Improvements in or connected with Vaccine-lymph Tubes.
I, JOIN HENRY MONTAGUE, of 101, New Bond Street, in the County of London,
Surgical Instrument Maker, do hereby declare the nature of this invention to be
as follows: —
My invention has for its object to provide means for expelling vaccine-lymph
from tubes without the necessity for blowing it out with the mouth as has hereto-
fore been usual.
According to my invention I provide a compression device consisting of a block
of india-rubber, preferably of conical or funnel shape externally and provided
with a longitudinal hole made slightly tapering the smaller end being in the
small end of the compression device. The larger end of the compression device
is preferably grooved upon the outer surface so as to render the rubber more
compressible than it would otherwise be.
In using my device the tube containing the vaccine-lymph is introduced into
the longitudinal hole and caused to project through the small end of the com-
pression device, the upper end of the said tube is then broken off whereupon the
tube is drawn so far through the hole that the broken end of the tube is some
distance below the surface of the large end of the compression device. The other
end of the lymph tube is now broken off and then the compression device, whilst
held between the first and second fingers with the thumb placed over the central
hole, is compressed and so compresses the air contained in the said central hole and
causes the lymph to be forced out of the lower end of the tube.

I, JOHN HENRY MONTAGUE, of 101, New Bond Street, in the County of London,
Surgical Instrument Maker, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
―
My invention has for its object to provide means for expelling vaccine-lymph
from tubes without the necessity for blowing it out with the mouth as has hereto-
fore been usual.

page_text: According to my invention I provide a compression device consisting of a block
of india-rubber, preferably of conical or funnel shape externally and provided
with a longitudinal hole made slightly tapering the smaller end being in the
small end of the compression device. The larger end of the compression device
is preferably grooved upon the outer surface so as to render the rubber more
compressible than it would otherwise be.
My invention will be clearly understood by reference to the accompanying
drawing, in which:
Figure 1 is an elevation:
Figure 2 is a plan; and,
Figure 3 a longitudinal section of my improved device.
1
a indicates my compression device having the tapering central hole b and the
external groove c. d indicates a tube for containing the vaccine-lymph.
In using my device the tube d, which is sealed at both ends, is introduced into
the longitudinal hole band caused to project through the small end of the com-
pression device, for instance as shewn in Figure 1. The upper end of the said
tube is now broken off and then the said tube is drawn so far through the hole b
that the broken end of the tube is at some distance below the surface of the large
end of the compression device, for instance as shewn in Figure 3. The other end
of the lymph tube is now broken off and then the compression device, whilst held
between say the first and second fingers with the thumb placed over the hole b,
is compressed whereby the air contained in the said central hole b is also com-
pressed and forces the lymph out of the lower end of the tube d.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
-
The improved device hereinbefore described and illustrated in the accompanying
drawing for expelling vaccine-lymph from tubes containing the same without the
necessity for blowing out the lymph with the mouth as has heretofore been usual,
substantially as described.
