I ARON JOSEPH MEYER of 117 Rue d'Aboukir, Paris, France, India Rubber
Surgical Instrument Maker, do hereby declare the nature of this invention to be as
follows:-
My invention relates to the pipes or nozzles of vaginal and other syringes or enemas.
Such pipes or nozzles are usually made of rigid material and are pierced with one or
more holes through which the liquid is ejected, and they are open to objection on
account of the hardness of the material, the roughness of its surface, and especially on
account of the size of the holes and the impossibility of excluding air from the
apparatus and its consequent ejection along with the liquid, and of the painful
cutting sensation produced by the force and volume of the jets.
The object of this invention is to remedy these imperfections by providing a pipe or
nozzle which is soft, smooth and polished, and which, in lieu of being pierced with.
open holes, is pierced with one or more slits opening only under the pressure of the
liquid, and acting as valves to prevent any return of air or liquid, whereby a more
complete douche or irrigation is obtained free from any mingling of air with the
liquid, or projection of air against the part to be treated. As the slits act as valves
to prevent the admission of air during the expansion of the compressible bulb of the
syringe, the use of the discharge valve may be dispensed with if desired.
The pipe is made of soft vulcanised indiarubber enamelled externally to give it a
smooth surface and terminating in a slight enlargement or bulb which is pierced with
one or more slits about three-sixteenths of an inch long, the slits being made by means
of a cutting tool which does not punch out any portion of the material, so that the lips
of the slits tend to close together and so act as valves giving passage to fluids only
from within outwards. The slits vary in number and occupy such positions as to give
the desired direction to the jets, according to the purpose for which the syringe or
enema is used. For a rectel enema there would usually be one end slit-only.

An Improvement in Syringe or Enema Pipes.
I ARON JOSEPH MEYER of 117 Rue d'Aboukir, Paris, France, India Rubber
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 ascertained
in and by the following statement :-
My invention relates to the pipes or nozzles of vaginal and other syringes or enemas.
Such pipes or nozzles are usually made of rigid material and are pierced with one or
more holes through which the liquid is ejected, and they are open to objection on
account of the hardness of the material, the roughness of its surface, and especially on
account of the size of the holes and the impossibility of excluding air from the
apparatus and its consequent ejection along with the liquid, and of the painful cutting
sensation produced by the force and volume of the jets.
The object of this invention is to remedy these imperfections by providing a pipe or
nozzle which is soft, smooth and polished, and which, in lieu of being pierced with
open holes, is pierced with one or more slits opening only under the pressure of the
liquid, and acting as valves to prevent any return of air or liquid, whereby a more
complete douche or irrigation is obtained free from any mingling of air with the
liquid, or projection of air against the part to be treated. As the slits act as valves to
prevent the admission of air during the expansion of the compressible bulb of the
syringe, the use of the discharge valve may be dispensed with if desired.
Reference is to be had to the accompanying drawing forming part of this
specification, which represents the pipe of a vaginal syringe with the slits distended as
by the emission of the jets of liquid. The pipe a is made of soft vulcanised india-
rubber enamelled externally to give it a smooth surface and terminating in a slight
enlargement or bulb which is pierced with one or more slits c about three-sixteenths
of an inch long, the slits being made by means of a cutting tool which does not punch
out any portion of the material, so that the lips of the slits tend to close together and
so act as valves giving passage to fluids only from within outwards. The slits vary
in number and occupy such positions as to give the desired direction to the jets,
according to the purpose for which the syringe or enema is used. For a rectal enema
there would usually be one end slit only.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, I declare that what I claim is..
A vaginal syringe or enema pipe or nozzle having its bulbous end pierced with slits
acting as valves, substantially as and for the purpose specified.
