RICHARD H. EDDY AND JOSEPH B. JOHNSTON, OF PROVIDENCE, RHODE ISLAND.

VAG'INAL SYRINGE.

SFEGIFIGATION forming part of Letters Patent No. 691,698, dated January 21, 1902.

Application filed May 31, 1901.

To all whom it may concern:

Be it known that we, RICHARD H. EDDY and JOSEPH B. JOHNSTON, citizens of the United States of America, and residents of Provideuce, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Vaginal Syringes, of which the following is a specification.

Our invention relates to certain novel improvements in vaginal syringes, so called; and it consists, essentially, of a tube member open at each end, having its walls provided with a comparatively coarse longitudinallyextending helically-arranged groove, the latter having a concave form cross-sectionally and being integral with an intermediate connecting-rib or slightly-raised portion having a convex shape, all as will be more fully hereinafter set forth and claimed.

In syringes of the class referred to it has been usual heretofore to provide them with straight cylindrical glass tubes. As thus constructed the device when in. use is liable to become accidentally displaced unless considerablecare be exercised in maintaining it in position. We are aware, too, that it has been proposed to provide the tubes of syringes or douches with annular corrugations or ridges; but such tubes do not wholly fulfil the requirements desired-that is to say, in the former case, wherein a smooth tube is employed, the fluid or liquid used for flushing or irrigating is forced out of the tube by means of the attached bulb in a comparatively straight and solid stream, so that considerable time is required to thoroughly reach and cleanse all the parts. In the case of the syringe having a tube provided with annular ridges the device may to some extent be retained in position better than one unprovided with such ridges; but its action in forcing the fluid therefrom is substantially the same as though the tube were smooth or non-corrugated.

The object We seek to attain is to overcome the objections or disadvantages inherent in syringes of the class forming the subject of the present invention, and to that end We provide the walls of the open tube with a coarse helical groove throughout, as before stated, thereby also forming a correspondingly-shaped groove in the inner surface of Serial No. 62,477. (No model.)

the tube. As thus constructed the tube can .be readily inserted, the adjacent membrane or parts when in use snugly fitting the surface of the tube and forming a water-tight joint or packing. By simply turning the device in the proper direction it can be inserted to the desired extent and maintain itself in position, the same being water-tight, as just stated. It can be readily withdrawn by turning it in a contrary direction and is not liable to drop out. By means of the inner helical groove the charge of flushing fluid is when inserted as in use discharged and distributed in a much more efficient and expeditious manner, since the charge enters in a more broken and spiral form, while at the same or less time the noveli nterior construction of the tube causes the charge to be deflected or diffused laterally, thus reaching and acting upon all the parts and thoroughly cleansing or treating them.

The accompanying drawing shows a side elevation, in partial section, of a vaginal syringe embodying our improvement. It is composed of'a flexible rubber bulb member 19, substantially as usual, and the tube member a, the whole being indicated by A. The said tube a may be made of glass, hard rubber, or other suitable material. The inlet end a is reduced in diameter to form a should ered head, over which is stretched the neck b of the said bulb, also as common. The other or discharge endm of the tube is open and out at an angle to the longitudinal axis. As drawn, the diameter of the tube is substantially cylindrical and straight, the same having a continuous shallow helical groove 0 formed in its wall and extending from the outer end to the head 0.. Intermediate of and parallel with the groove c'the tubes surface is provided with the slightly-raised or rib portion a. We prefer to make the form of said parts 0 c concave and convex, respectively, as clearly shown. As thus constructed, it will be seen that the interior surface of the tube has a helical form corresponding with that of the exterior, the walls or shell being substantially uniform in thickness throughout.

As before stated, certain forms of construction of the tube'member are old. There inbefore described, the same being open at each end and having its Wall provided with alongitudinally-extending helical groove and acorrespondingly-shaped rib alternating with said groove, and having one end of the tube adapted to be attached to a flexible tube or bulb, substantially as described and for the purpose set forth.
