The improvements relate to irrigators for body cavities, especially the stomach and intestines.

The therapeutic value of a proper irrigami tion of the intestines, for example, is exchief object of the present invention is to provide an apparatus or device whereby the same character and quality of results may be obtained by the individual in his own home, and without an operator or attendant.

Such cleansing of the intestines is far more than that accomplished by the simple enema. The present improvements are designed to effectuate a regulable inflow of liquid, say water or water charged with a medicament, and then Aan outflow or discharge, the applicator tube remaining inV place within the body cavity, however, and the alternate operations of inflow and outflow being often repeated, the catheter or tubular flexible applicator being gradually inserted more and more deeply within the body cavity. This method of treatment is not new.

Other general advantages and certain speciflc objects in connection with details or parts of the construction or organization will appear hereinafter.

In. the drawings Figure 1 is an elevation of my improved device complete, in a simple form; Fig. 2 is an enlarged vertical section through what I sha-ll call the connection member of Fig. 1; Fig. 3 is an enlarged'vertical section, as on the line v3 3 of Fig. 4, of a form of the connection member modified by the addition of aV valve; Fig. 4 is a vertical section at right angles to the view of Fig. 3, as

on the line 4 4 thereof; Fig. 5 is an edge view of the device ofFigs. 3 and 4; and Fig. 6 is a sectional view as on the line 6-6 of Fig. 4. i

Referring to Fig. 1, the device illustrated showsV a source of liquid supply 10 yin the form of a rubber bag which maybe supported as by hanging it upon a nail in an elevated position. The rubber tube 11 -extends downward from the bag 10 and carries means 12 for regulating the amount of liquid being used. yThe element 12 may be a valve proper or a constricting device adapted to compress the tube and limit its cross area at that place. This feature for regulating the flow is highly important since certain users lare able to work with only a limited amount of liquid, and in any event it is at times i" desirable to reduce the flow temporarily to enable the liquidto penetrate more gradually among the folds, bends, etc., in the tissues as well as into the material which it is desired to loosen and remove.

The tube 11 then extends beyond the regulator 12 to the connection member 13V which is shown on a largerscale in Fig. 2. Means for controlling the liow through tube 12, as to open and close the tube, are shown in Fig. 1 as an ordinary spring clip 9 of the kind universally found on the ordinary enema outfit. ,y

Turning to Fig. 2, the connection member 13 has an intake port 14l defined by a nipple 15 integral with the body ,13, the nipple being frictionally inserted into the lower end of the tube 11. From'the port 14 a passageway 16 extends first downward at the part 16a, ythence across at part 1Gb and thence upward at the part 160 to a discharge port 17 the side and place of which is indicated bythe arrow 17 in Fig. 1.

The body 13 has a nipple18 surrounding the port 17, and on the nippl-e 18 is one end of '85 the flexible hollow bulb'19. A short transparent tube 20, as glass, enters the other end of the bulb 19, whilethe vcatheter or applicator 21 is stretched upon the outer end of the glass tube 20. The applicator has an opening 21a for discharge and intake.

Since the connection members in all of the figures of the drawings arethe same except for the valve shown in Figs. 3 to 6, the corresponding parts may be numbered the same,

Reverting to the device of Fig. 2, there is a port 22 (Fig. 3) directly opposite the port 17 and defined by the nipple 23. The port-s or passageways 17 and 22 of the device of Fig. 2 are in a straight line and directly in communication with each other, and the passageway 160 of Fig. 2 opens directly into both of the ports or assageways 17 and 22.

Reverting to ig. l there is a discharge tube 24 on the nipple 23 and carries a clip 25 for opening and closing the discharge conduit.

Vith this understanding it will be clear from Fig. 1 that should the clip 25 be operated to close the tube 24 and the clip 9 on the tube 11 be released, liquid will flow downward through the passageway 16 to the port 17 and thence through the bulb 19 and glass tube 20 to and y through the applicator 21.

I have found that when a quantity of water has thus been injected notably advantageous results are hand if the water in the body cavity be agitated. To this end the operator squeezes upon and releases the bulb 19 causing a back-and-forth surge in the applicator and consequently a disturbance of the water in the body cavity. I believe this feature of agitation is new, and it is peculiarly valuable and important in a device for individual use. A very valuable feature of it is that it serves also to maintain the catheter and its opening as 21 free of clogging.

I/Vhen it is desired to discharge water, solid matter and the gases therewith the clip 14 is operated to close the tube 11 and the clip 25 is operated to open the discharge pipe. Thereupon the flow passes from port 17, (Fig. 3) to port 22 and thence through the discharge pipe.

In this connection note that the liquid trap consisting of the passageways 16a, 166 and 160 is between the intake port 14 (Fig. 2) and the discharge ports 17 and 22.V Substances coming from the body cavity may not, therefore, pass upward into the passageway leading to the source of liquid supply to contaminate it. Especially important, however, this provision makes against the passage of gases into the pipe 11. Wvere the liquid sup- `ply led directly to the passageways 17y and `22 as by a simple inverted T pipe connection, such gases would replace liquid in the supply conduit at least to the extent between the elevation of the passageway 17, 22 and that the clip 14. Then on the ensuing inflow through the catheter that gas would be carried back into the body cavity. In some cases this would be very painful, and in any event it would militate against the results. This feature of preventing the reintalre of gases is believed to be new. y

Referring now to Figs. 3 to 6 theonly essential modification from the connection member thus far describedr is in the provision of a valve therein for controlling the discharge into and from the body cavity.

This valve comprises a plug 30 fitting into the body 13a in the direction shown by Fig. 4. There is packing at 31, a screw cap 32 holding the parts in place, and a handle 33 by which the plug 30 is turned.

Fig. 6 shows that the plug 30 has a gateway 35 through it which, in the position there shown, opens into the trap passageway 160, thereV being another opening or port 36 at right angles to the port 35 which opens into the port 17 of the body 13a. The position shown in Fig. 6 provides for a discharge of liquid from the source into and through the catheter. Now when the handle 33 is swung to the other side, as viewed in Fig. 5, the port 36 (Fig. 6) moves upward and becomes closed while the vertically shown port 35 is moved into the horizontal position and puts the ports or passageways 17 and 22 into communication with each other. This last-mentioned position provides for the outflow of sons mentioned in describing the connection device of Figs. 1 and 2. This arises from the fact that while'such valves stop water they do not ordinarily stop gas.

Turning to Fig. 5 note the ear- like projections 36 and 37 integra-l with the body 13a. The handle 33 swings between these projecting elements and for one thing they serve as stops for the handle in its lateral movements. They are functional also in serving as finger supports in operating the valve. This body as 13a; with its associated parts shown in Fig. 1 is hanging' freely at the end of a fleX- ible tube. IVith the ordinary type of 'valve two hands would be required. tooperate it, one for holding the body andthe other for moving the valve.` ports 36 and 27 the handle 30 maybe moved from either position to the other by a pinching action between the'thumb and finger of one hand. This feature is peculiarly important in an individually-operated flushing device since one handof'the'operator is advantageously used at the time in connection with the catheter.y The user of this type merely moves the handle 33'back and forth to Vcontrol the inflow and outflow, while according to the device of Fig. 1 the clips 9 and 25 must each be operatedwhenever the direction of the flow is changed.

It is to be understood that the body 13a of Figs. 3 to 6 may be applied to the other parts shown in Fig. 1 in place of the body 13, omitting the clips 9 and 25, and for the purposes of the claims the body marked 13 in Fig. l may be considered Veither 13 or 13a. The

Vith the finger supapparatus equipped with the connection device of Figs. 3 to 6 is the preferred construction.

Note from Fig. 3 how the passageways marked 17 and 22 incline downward in the direction of flow into the body cavity. I have discovered the peculiar fact that if the inflow be in a horizontal or upwardlyinclined direction past a valve a very considerable quantity of air becomes entrained by the liquid and passes into the body cavity, interfering with the results, while, on the contrary if the intake be downward past such valve, the entraining of air is substantially avoided. Such valves do not ordinarily exclude air, especially after wear. I believe the entrainng of air to be overcome in the arrangement shown because of the greater density of the liquid over that of the air, the air being mechanically excluded rather than enveloped by the stream at the valve. This inclination of the passageways 17 and 22 is also advantageous in the return or outflow or discharge since the body gases passing through the device tend to rise, and in passing through the connection device exert a motive force upon the stream and aid the flow of heavy matter therethrough. There is also a siphonic action aiding the discharge, due to the low level of the end of the discharge tube 24.

An important feature of the present device is that it occupies but little space when in use or when put away. It avoids the use of a framework or stand for supporting it. It unites the convenience in use of the simple enema outfit with vastly superior therapeutic results.

In my practice the connection device body is a metal casting. The rubber tubing, catheter, etc. are stock or standard devices or elements well known.

I contemplate as being included in the present invention all such changes, variations and departures from what is thus specifically illustrated and described as fall within the scope of the appended claims.

I claim:
