Patented Jan. 22, 1952 UNITED STATES RECTAL IRRIGATOR Maurice H. Kowan, Los Angeles, Calif.

Application August 5, 1947, Serial No. 766,151

1 Claim.

My invention relates to a self adjusting, self retaining rectal irrigating device adapted to be removably applied to a toilet bowl and maintained in position thereon by the toilet bowl seat, thus enabling the tube to yield readily in all directions so as to be used without undue discomfort to the user and, further, to provide a device of the character referred to, which will enable the user to sit conveniently on a toilet bowl while fluids are delivered to the rectal ampulla, to loosen and dissolve the intestinal contents and enable same to discharge without the necessity for` withdrawing the device from the rectum.

With the foregoing and other objects in view,

my invention consists in certain novel features' of construction and arrangement of parts which will be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:

Fig. 1 is a vertical section showing portions of a toilet bowl and cover with my improved irrigator in position thereon and with portions of the tube in vertical section.

Fig. 2 is a horizontal section taken on the line 2 2 of Fig. 1.

Fig. 3 is a cross section taken on the line 3-3 of Fig. 2.

Figs. 4 and 5 are cross sectional views taken respectively on the lines 4-4 and 5-5 of Fig. l.

Referring by numerals to the accompanying drawing, which illustrates a preferred embodiment of my invention, I designates a conventional toilet bowl, and II, the seat thereof.

My improved irrigator, which is in elfect, a one piece structure, includes a substantially rectangular block I2 of rubber which is adapted to be clamped between the bowl I and seat I I, with a ilexible tube I3 formed from closely coiled wire, or a narrow strip of metal, embedded in said block.

One end of exible tube I3 extends through a nipple on the rear end of block I2, thus enabling ready attachment of a ilexible tube I5, connected to a water bottle I6 or other source of liquid supply.

The opposite end of exible metal tube I3 projects a short distance from block I2 as designated by I3a and suitably connected thereto is one end of a substantially U-shaped metal tube Il.

The opposite end of this tube I'I is suitably connected to the lower end of a flexible metal tube I8, formed of closely coiled wire or a narrow strip of metal and which has a length of three or four inches, thus providing a flexible tip or nozzle.

Flexible tube I3, metal tube I'I and flexible tip I8, are wholly enclosed or sheathed with a coating I9 of rubber, flexible composition or the like, same extending a short distance beyond the free end of tip I8 and provided, preferably on its side, with a discharge aperture 20.

Thus the rubber sheath is integral with the outer end of block I2 and as all metal parts of Number Number PATENT OFFICE the irrigator are rubber or composition covered, same can be readily cleansed, sterilized and maintained in a sanitary condition.

To use the irrigator, block I2 is clamped between bowl I) and seat II as seen in Figs. l and 2, with flexible tip I9 projecting upward at 0r near the center of the seat opening.

When the tip is inserted in the rectal cavity, it automatically lends itself to the contour thereof, exes readily in all directions and rests comfortably without undue pressure or strain against the rectal wall.

Flexible extension I3a of tube I3 enables tube I'I and tip I8 to move vertically for automatic adjustment while the device is in use, as shown by dotted lines x, Fig. 1.

Water, plain or medicated, ows from bag I6 through tube I3 and tip I8, discharges from aperture 20 into the rectal ampulla to dissolve, loosen and bring about the discharge of the fecal matter, without necessitating removal of the tip.

Due to the iiexible extension I3a, the U-shaped portion of the device including tip I3 may swing laterally as well as vertically with the body during the irrigation function.

Thus it will be seen that I have provided a rectal irrigator, which is simple in structure, inexpensive of manufacture and very effective in performing the functions for which it is intended.

Minor changes in the size, form and construction of the various parts of my improved rectal irrigator may be made and substituted for those herein shown and described, without departing from the spirit of the invention, the scope of which is set forth in the appended claim.

I claim as my invention:

In a rectal irrigator, a block, a exible coiled wire tube passing lengthwise through said block the outer end of said coiled wire tube and said block being extended to form a nipple for the attachment of a source of water supply, a U-shaped tube connected to the other end of said coiled wire tube, a coiled wire tube connected to the opposite end of said U-shaped tube, a continuous sheath of soft flexible material integral with said block and enclosing both coiled wire tubes and said U- shaped tube, and the free end of which sheath is provided with a jet opening.
