Specification of Letters Patent.
Application filed April 21, 1914. Serial No. 833,409.
To all 'whom 'it may concern:
Be it known that I, CHARLES O. Rien, a citizen of the United States, residing at Denver, in the county of Deliver and State of Colorado, have invented certain new and useful Improvements in Vaginal Syringes, of which the following is a specification.
My invention relates to `certain new` and useful improvements in vaginal syringes and more particularly in syringes of thetype shown and described in Letters-Patent of the United States, No. 930,312, and No. 973,456, issued to FranlrA. Neveu, respectively on August 3, 1909, and October `18, 1910, of which Letters-Patent I have become the owner by assignments duly recorded in the United States Patent Oflice.
The syringe as shown and described in the patents above mentioned, comprises a piston chamber which at its opposite ends, connects with two separate passages which at the mouth of the nozzle of the instrument, are in communication.
By moving a piston to and fro in the chamber, a part of fluid with which the latter has been supplied, is discharged through the nozzle from the portion of the cylinder` at one side of the piston, While the part previously ejected, is at the same time compelled to renter the chamber at the opposite side of the piston.
By the use of the instrument, the liquid is thus alternately ejected and returned through the two passages which connect the chamber with the mouthof the nozzle, and the liquid With which the instrument had been supplied previous to the operation, is
thus used over and over and compelled to continuously circulate through the vaginal cavity to thoroughly cleanse and medicate every portion and fold thereof.
In the use of an instrument constructed in accordance with what is shown and described in the patents, it was found that While the principle on which it operates is undoubtedly productive of highly beneficial results, certain heretoforeunnoticed defects in its construction rendered it incapable of performing its functions as completely and effectively as is required in a device of this character, and it is the object of the present inj vention to provide certain improvements in the construction of the instrument which Will eliminate the objectionable features and thereby render the device capable of performing its functions so as to thoroughly and adequately fulfil the purpose for which it is designed.
One of these improvements consists in providing the divisional Wall of the two duets` which connect the opposite ends of the piston chamber with the nozzle of the instrument, with one or more passages for the flow of air from oneof the said ducts to the other. 4
In the use of the instrument as originally coutructed, it was foundto be difficult to fill the piston chamber with the medicinal preparation, prior toits being inserted into the vaginal cavity, and in its operation, it Was observed that but a part of the fluid returned into the chamber during the movements of the piston, While the greater part, being prevented from entering the chamber by the presence of air, remained in the cavity.
The provision of passages which connect the duets adjacent the outer end of the pis-` ton-chau'lber and the orifice of the nozzle, completely eliminate the above defect in the operation of the instrument by permitting the escape of air from the chamber at either side of the piston, duringthe inflow of liquid.
Other improvements consist in tapering the nozzle of the instrument interiorly as well as exteriorly, in eliminating all external protuberanees on the nozzle, such as the ridges shown in the patents, and in providving abutments for securing the shield which in the use of the instrument closes the mouth of the vagina.
In using the instrument constructed in ac-` cordance with the above mentionedpatents, it was found that the stream of fluid Was ejected from the mouth of the nozzle in a more or less flat condition, engagedbut a portion of the vaginal cavity and was by forcible contact With the Wall of the cavity,
dissipated so as to have but little effect on other parts of the same. This defective result was caused principally by the shape of .the nozzle which interiorly is of uniform diaineter and offers no resistance to the flow of 1fluid from the semi-circular ducts, and in the present construction it has been remedied b tapering the `nozzle interiorly for the pin-,4x pose of offering a resistance to the flow` of liquid from the ductsand giving it an opportunity of collecting! in the outer end of the Patented Oct. 27, 191e.`
nozzle before being ejected through the mouth of the same.
As a result of the improved construction, the liquid is ejected from the nozzle in a compact, substantially cylindrical stream which will engage every part of the cavity and retain its form until after the direction its flow is reversed for its return to the instrument.
lWith the same end in view, 1 have provided the two ducts which connect the ends of the piston chamber with the nozzle of the instrument and which in the original device were made by partitioning a circular conduit of two independent circular conduits which deliver the liquid in cylindrical instead of flat streams.
rlhe exterior taper of the nozzle facilitates its linsertion into the vagina and prevents possible injury to the mouth and wall of the same, and with the same object in view, its exterior surface is made continuous with that of the shield and free from ridges or other protuberances.
The abutments provided to engage the shield required to prevent the escape of liquid from the vagina, firmly hold the same in a determinate position and prevent its displacement.
1n the construction of the patents the shield is adjustable to different distances from the end of the nozzle, and it was found inusing the instrument, that the rearward pressure on the shield, often caused it to slip back on the nozzle, thereby causing the latter to move further into the vaginal cavity than' is required, with considerable danger of forcibly engaging and possibly injuring the wall of the same.
ln addition to the improvements mentioned, it was found thatthe length of the nozzle of the instrument as shown in the drawings, caused part of the fluid to collect around the same at the mouth of the cavity which was detrimental to effecting a circulatory movement of the entire body of liquid with which' the instrument is filled, as is desirable to elfect a thorough cleansing and medication of every part of the cavity.1
1n the accompanying drawings in the various views of which like parts are similarily designated, Figure 1 represents a longitudinal, axial section of a syringe of the character described in which my said improvements are embodied, Fig. 2, a fragmentary section taken along the line 2-2, Fig. 1, kdrawn to an enlarged scale, and Fig. 3, a transverse section along the line 3 3, Fig. 1.
The reference numeral 2 designates the interiorly cylindrical body portion of the instrument which at one of its ends 1s closed by a head 3.
A piston l slidably fitted in the cylinder is secured at the end of a rod 5 which passes ber, by tvo passages the nozzle.
through a stufng box 6 on the head and is provided at its opposite extremity with a ring 7 to facilitate its manipulation.
A nozzle 8 projecting forwardly from the forward end of the cylinder at one side thereof, is divided into two cylindrical conduits 9 and 10, one of which connects with the interior of the cylinder at the forward end thereof, by means of an inwardly flaring opening 13, while the other extends e'x- `teriorly of the piston-chamber and is connected with the opposite end of the same by means of an opening 14. lThe forward portion of the nozzle is tapered to provide the contracted chamber 15 in which the flow of the liquid discharged from either of the conduits into which the nozzle is divided, 1s
restrained before it is ejected through the mouth of the nozzle, for the purposes hereinbefore explained.
rlhe two conduits are connected for the escape of air from one to the other for the purpose mentioned hereinabove, at points adjacent their outer extremities and adjacent the forward end of the piston cham- 12 which are formed in the divisional wall of the conduits within rlhe tapering end portion of the nozzle is exterior-ly smooth and free from irregularities, to facilitate its introduction into the vaginal cavity, and its rearward portion adjacent the cylinder hasl two shoulders formed by circumferential ridges 16 and 17 between which is rigidly secured the exteriorly concave shield 18 which in the use r4of the instrument'closes the mouth of the Jcavity into which the tapered end of the nozzle is inserted.
The shield is made of flexible rubber and the shoulders between which it is held are made of sufficient width to positively prevent displacement of the same in either di-` rection.
rilhe peripheral ridge of the nozzle which provides the outer one of said shouders,
'flares exteriorly to evenly connect the exterior surface. of the tapered end of the nozzle with that of the shield.
By this construction the parts of the instrument which come in contact with the mouth and the wall of the vaginal cavity, present from the extreme end of the nozzle 5to the outer rearward edge of the shield, one continuous smooth surface which eliminates every possibility of injury to the parts 1engaged by the instrument while it is in operation.
Having thus described my invention what 1 claim and desire to secure by Letters-Fatent is 1. A vaginal ysyringe of the character described comprising a piston-chamber, a piston therein, and a nozzle projecting 'from the forward end of the chamber and inscribed comprising a piston-chamber, a piston therein, and a nozzle projecting from the forward end of the chamber and including two cylindrical conduits which communicate respectively with openings at opposite ends of the chamber and which are connected by passages at a point adjacent their forward extremities, andat a point adjacent the fori ward end of the chamber.
In testimony whereof I have affixed my signature in presence of two witnesses.
