This invention concerns a syringe, spray or douche, as used for washing cavities of the human body. Its principal eld of application is in female hygiene.

One of the objects of the invention is to iacilitate the introduction of the applicator of a syringe, and to distend mucous membranes thereby, so that they are exposed for a thorough ablution.

According to another object of this invention the tract to be rinsed or washed is distended spacedly relatively to an irrigating spray stem or nozzle, so as to permit free play of a cleansing solution upon the surfaces or membranes to be cleansed.

This invention further provides for dispensing means, which cause-a regulated flow of cleansing uid, along a preferred, e. g. helical path.

Another object of this invention vprovides for a construction and arrangements of the channels delivering a cleansing fluid to spray nozzles in such fashion, that a high velocity of flow of the fluid is obtained, yielding a high cleansing efficiency by Way of dynamic action.

This invention also has the object to incorporate parts in a syringe particularly adapted for vaginal douches which'allow a ready conversion for other syringing, such as enemas, if emergency should so require.

These and other objects of this invention will be better understood from the following description and the accompanying drawing, which shows a specic embodiment of the instant invention, but is to be interpreted as illustrative and not in limitation of the improvements.

lustrating a preferred inclined arrangement of the perforations.

Similar numerals refer to throughout the various views:

The device essentially comprises in a douche similar parts a shield and a contractile applicator extending therefrom. The applicator comprises an exterior tensile spreading member, into which a spray is spacedly placed.

The frame work of the shield I0 comprises an outer flared cup II having a beaded edge I2. .It 5

.may accommodate a reinforcing disc I3 at the bottom. The cup II, together with disc I3 contained therein, is assembled end to end with a at saucer I4 by a central guide bushing I5, which slidably accommodates the perforated hollow stem I6 of applicator I'I, and by the drain nipple I8, which is laterally offset relatively to bushing I5.

The central guide bushing I5 rests with a shoulder I9 on the flat saucer I4 and extends with its shank through central openings in said saucer I4, the cup II and reinforcing Adisc I3 and then through -a spacing sleeve 2@ and is pressed, spun or peened over the latter, so that parts I I, I3 and I4 are pressed together and held in rm abutment.

Nipple I'S may be flanged at one end by a collar 22, and is engaged at that end by a hollow screw 23. Screw 23 serves as an outlet and extends through openings in parts II, I3 and I4 and draws said parts into abutment with each other.

Over the other, thickened end 24 of nipple I8 is slipped a short hose 25, which connects with a cock or valve serving to control the draining of a liquid used in the device by way of manipulation. The drawing showsfor such purpose a cock 26, which is controlled by a push-button 21. From the other end cock 26 extends a hose 28, which may lead, for instance, to a waste bowl (not shown). The irrigating stem I6 has a stop collar 29 upon its outside, said collar seating against the lower end of the central guide bushing I5, when the irrigating stem is in the top position shown in the drawing.

Opposite ends of irrigating stem I6 are tapped.

In the lower threaded end of stem I6 is permanently mounted a double threaded bushing 3l), on which a bulbous connector 3| is removably mounted. Bushing 3b is threaded on its interior 40 to the extent to which it is engaged upon the double thread 3U. The bulbous connector 3| is of a larger diameter at its upper end 32, is kcontracted below said upper end 32, and then larger again at its lower end, in order to offer a grip for a liquid supply conduit. As a supply conduit the drawing shows a rubber hose 33, which is enlarged into a bulb 34 intermediate its ends, and carries at its end a poppet valve-35, which permits a uid to be taken in and to flow in one direction, after the bulb 34 has been squeezed and is released, the fluid taken in being ejected byv way of the irrigating stem I3.

A syringing liquid taken in `by way of poppet valve 35 will be readily ejected .from the upper end of .irrigating stem I6` by way yof `the small openings 36 provided on all sides of said stem I6 as perforations, and by Way of the central opening 31 in bulbous head 38, which is superimposed upon the irrigating stem I6 by way of the nozzle 39. Nozzle 39 is shown in full in Fig. 2, and comprises at the base threaded sections 40 and 4l, which are separated from each other by the shoulder 42, and which are engaged in the arrangement of Fig. 1 upon the bulbous head 38 and the stem I6, respectively, thus constructively connecting the two parts. From the threaded end of the nozzle 39 extends a shank 43, which-I has a taper bore 44. Upon the outside the shankV` 43 has an intermediate constriction 45, but has substantially the same diameter at opposite ends, which predeterminedly and spacedly clears the inner wall of the irrigating stem I6, when the shank 43 extends into the irrigating Ystem I6 in the manner shown in Fig. l. l

Shank 43 restricts passage in stem I6 for th syringing liquid and causes it to flow at a comparatively high speed, when it approaches the openings 35 and 31. Thus the liquid leaves the openings at a considerable force of movement, being at the same time, expelled with substantially the same force in a number of jets from all the openings.

Tensile means like a coiled spring clear the space around stem I6 for play of the jets, and an open coil will cause the liquid to whirl in a tract. Thus a helical spiral spring 46 is seated at its large end by way of at least one complete convolution in the saucer I4; whereas its narrow,

closely wound upper end 41 is iixedly engaged upon the tapered shank of bulbous head 38 and in groove 48 at the point of narrowest cross-section of said shank.

A suitable gasket facilitating closing around the orifice of a tract is placed around the parts Il, I4. The drawing shows for such purpose a sponge rubber annulus 49 having a solid top 59.

For use of the device assembled in accordance with Fig. 1, the valve end 35 is placed into a container holding the syringing liquid, Whereas the hose 28 is connected to waste. In reaction against spring 46 the applicator is Withdrawn and the device is placed in` position, annulus y49 closing around the vulva. The applicator is then slowly released, so that the head 38 and the spring 46 enter upon and spread the vagina. The syringing is then effected by manipulating bulb 34, thus pumping the syringing liquid for the douching. During and after syringing the syringing liquid is drained by manipulation of push-button 21.

When the device is to serve as enema for children, nozzle 39 is connected to the irrigating stem I6 to extend out therefrom, instead of into it, as shown in Fig. 2. Bulbous connector 3| serves as a protective sleeve, and the short hose 25 may be slipped over the stem I6, in order to close the openings 36.

For an enema for a grown-up person the stem I6 and the nozzle 39 are assembled with each other in the same manner as shown in Fig. 1 and the bulbous connector 3l is placed thereover as indicated in Fig. 3.
