i Application filed June 25, 1898. Serial No. 684,510. (No model.)
To all whom t may concern:
Be it known that I, HENRIoUs WALLACE WESTLAKE, residing at Los Angeles, in the county of Los Angeles and State of California,
have invented a new and useful Vaginal Irrigator, of which the following is a specification.
This invention relates to syringes or other forms of irrigators by means of which to cleanse the vaginal cavity to remove impurities therefrom and to apply -medicinalprepa'- rations to the parts aifected.
An object of my invention is to provide means for applying the liquids directly to the affected parts with an elfective force, butin such a manner that there will be no deleterious results, but the cleansing will be perfect.
It is an object of my invention to avoid any regurgitation and to immediately 'remove from the cavity all of the vitiated liuids.
My invention relates to the nozzle-head by which the application of the liquid is made, and also relates to the construction of the appliance With relation to the immediate removal of-the liquid from the cavity Without any regurgitation.
I have discovered that the difficulty heretofore experienced in cleansing all'of the parts of the cavity by means of a syringe or other form of i'rrigator arises largely from the fact that the irrigators heretofore used have been sol constructed that the action of the liquid on those parts which are most subject to disease and which are most usually affected is mainly reflex and is not direct. So far as I am aware no vaginal syringe has heretofore been provided that could make a continued application of the liquid directly tothe external os, the neck, and lower portion of the womb to remove .the impurities therefrom. On the contrary, the expediency of the use of such a syringe has heretofore been considered doubtful. These parts are peculiarly sensitive, but they are also peculiarly exposed to and subject to affection, and an object of my invention is to provide a vaginal syringe. by means of which these delicate parts can be thoroughly cleansed. In some syringes of which I am aware it has been proposed .to perforate the ends of the nozzle, so that a stream is thrown directly forward, the
body ofthe syringe rearward of the nozzle being enlarged, and thereby forming an obstruction to the immediate discharge of the liquid, thus causing a damming up of the liquid within the cavity suicient to obstruct thedirect action of the forwardly-directed streams, whereby the retained liquid affords a measurable protection to the delicate parts, but at the same time prevents their absolute cleansing. In order to provide for a perfect cleansing of the cavity any damming up of t-he liquid vmust be avoided, and I provide against any deleterious action of the cleansing-streams by so constructing my nozzlehead as to produce extremely fine and delicate though forcible streams or jets of liquid from the end of the nozzle. This I produce by so constructing the nozzle as to combine hydrostatic action with great frictional resistance-that is to say, my newly-invented nozzle-head is provided with comparatively very thick walls with very fine dischargeoutlets therefrom, the same being minute tubular ducts, the length of which is over three times the diameter, and these issue from an enlarged chamber Within the head, which is supplied through an inlet of less diameter than the chamber and of greater cross-sectional area than the combined cross-sectional area of the outlets. By this means the liquid is supplied vto the outlets under hydrostatic pressure-that is to say, the liquid in the chamber is practically undisturbed and there are no cross-currents within the chamber to interfere with the even and constant supply of the liquid to any and every outlet. Then the liquid in passing through each of the outlets is subjected to great friction, so that the issuing stream is much finer than can be produced by any means other than my device, sof
far as I am aware; but such streams may be made to issue with great velocity and a consequent considerable force which is ample to edectively remove the impurities from any diseased surface within the cavity; but the streams do not have such momentum Vas to prove deleterious. It is insufficient for the purpose of my invention that the fine perforations be used without a hydrostatic supply, for it is important for the purpose of my invention that the streams while fine, so as to have but little momentum, shall have com- IOO effect. My syringe is also provided with a thin case surrounding the supply-tube rearward of the nozzle-head, a chamber being provided between the supply-tube and the case and inlets being provided into said chamber, which inlets are large and spirally arranged all around the tube, so that the liquid finds immediate exit therethrough from all sides and without being dammed up within the cavity. The case is of the saine diameter as the nozzle-head to form a straight cylinder therewith, and the use of all tampons are dispensed with, so that there is no obstruction to the outflowing liquid, and I avoid all regurgitation and all retention of any impurities.
My invention is a notable departure from all vaginal irrigators heretofore known, in that by means of it it is possible to safely and without shock, discomfort, or inconvenience to the patient apply the liquids (with a force eil'ective to remove all impurities) direct in front of the nozzle to cleanse the external os, the neck, and the lower portion of the womb, at the same time removing all impurities from the entire vaginal cavity. The nozzle-head is so constructed and the discharge perforations or outlets are such that the cleansing and medicinal liquids are thrown direct forwardly and also laterally in individual and very line forcible jets which project themselves against the parts named, so that all such parts are acted on by the freshly-injected jets of the liquid before such liquid has come into contact with other diseased parts or impurities therefrom, and the force of each jet can be sufficient under a convenient pressure by bulb or fountain to cleanse where it strikes, and yet be so gentle as to cause no inconvenience to the patient. The perforations are mere pin-holes in diameter and are arranged very close together. The head which I have used is circular and is five-eighths of an inch in diameter. The perforations are one thirty-second of an inch in diameter and pass through walls five thirtyseconds of an inch thick from a chamber fivesixteenths of an inch in diameter, which is supplied through a circular inlet which is three-sixteentbs of an inchin diameter. With these dimensions I have used thirty-three'and thirty-four perforations successfully. Care must be taken that the aggregate capacity of the outlets is less than the capacity of the inlet which supplies the expanded chamber.
My irrigator differs from all previous forms in that the head of the irrgatorhas numerous very fine and closely-arranged discharge-passages, the aggregate capacity of which is less than the capacity of the supply-opening into the head, and said passages are promiscuously arran ged-that is to say, in spiral or staggered rows and not in longitudinal series-and they open from a chamber in the head, which chamber is of larger cross-sectional area than the inlet, and the length of the bore of said passages is much longer than the diameter, so as to give direction to the issuing streams and to project such streams as individual jets to a considerable distance under a gentle pressure. The length of each outlet is preferably equal to from four to five times the diameter thereof, so that the friction of the walls upon the issuing stream modifies such stream and causes it to be very fine and gentle, though eective in its cleansing action, so that direct application can be made to thoroughly cleanse tender parts which heretofore could be cleansed only by local treatment. The promiscuous spiral or staggered arrangement of the outlet-openings of the head causes the issuing jets to operate more effectively in cleansing the cavity than if theoutlets were arranged in series-tl e., in straight rows-longitudinally along the head. It' arranged in straight rows extending lengthwise of the head, the space between the rows of jets will not be so effectively cleansed, the action of the rows of jets being much as though the liquid were discharged through parallel slots, thus failing to cut up and wash away the impurities lying between the lines where the discharge is effective.
By means of the direct method of application which is made possible by my invention iniiarnmation of the uterus, vaginal walls, including the anterior wall of the rectum, the external os, neck, and, in cases of prolapsus, the lower part of the womb can be reduced and the parts perfectly cleansed by the direct application of hot water or solution. This is not possible with any of theirrigators heretofore known. The endwise perforations of the head are virtually and actually forward extensions of the bore of the injectingtube, and the cavity of the head is expanded beyond the inlet and is in the expanded portion so large, compared with the inlet, as to give the effect of hydrostatic pressure to force the liquid through the fine perforations and to avoid forming any currents across the inner mouths of the perforations--that is to say, my nozzle-head is so proportioned and constructed that the streams are thrown with equal and even force from all the perforations lalike under any given pressure.
My irrigator comprises the combination, with an inner injecting-tube and an outer discharge tube or case, a discharge-chamber being provided between such tubes and said tubes terminating in about the same plane, of a nozzle-head of the same circumference as the tube and having an expanded chamber with comparatively thick walls, with fine perforations, a short neck externally and :internally screw-threaded, the injecting-tube being screwed into the neck and the neck screwed into the case. These members are easily taken apart and cleansed. The inter- IOO IIO

The chamber in the head being of greater diameter than the interior of the inlet-tube avoids the production of currents across the inner mouths of the perforations and gives greater force to the issuing streams, in accordance with the laws of hydrostatics, thus forcibly applying the liquid to the aected parts and washing and cleansing the parts withgreat efficiency. The liquid introduced is free from any contaminations until it has reached the parts desired, vand the outlowing liquid passing along the case enters the inlet-openings and lioWs out from the outlet c. Arrows in Fig. 3 indicate the course of the liquid. The outlet-tube c also serves the purpose of a handle.
The instrument may be made of metal, hard rubber, or any other suitable material.
