PULSATING IRRIGATOR Filed May 14, 1927 I5 Sheets-Sheet 3 Patented Feb. 23, 1932 HARRY HERTZBERG, OF BROOKLYN,'NEW YORK PULSATING IRRIGATOR Application filed May .14,

This invention relates to hydraulic irrigating apparatus for use in irrigating the intestinal canals.

An object of the invention is to provide such a device with a pulsating delivery which will have a massaging effect upon the walls of the intestines'and which, by intermittently expanding the intestines, will break loose anyconcretions that may be adhering thereto. This hydraulic vibratory massage has a stimulating and beneficial influence on the intestinal tissues and breaks up and washes away adhering toxic matter that could not otherwise be removed. v

A further object is the provision of means for varying the force and frequency of the pulsations to adapt the treatment to the condition and needs of the patient. a

The apparatus is particularly useful for administering high enemas, since the alternating stretching and relaxing of the bowel walls assist in inserting the head of the irrigator' into the upper intestine. V 4

While preferred forms of the invention have been disclosed for purposes of illustration, it should be understood that changes may be made in the structure without departing from the spirit and scope of the 1nvention as hereinafter set forth and claimed.

In the drawings: Fig. 1 is an elevation of one embodiment of the invention.

Fig. 2 is a section through the interrupter valve of Fig. 1.

Fig. 3 is an enlarged elevation of the nozzle used in Fig. 1.

Fig. 4 is an elevation partly in section of a modified form of the invention. 7

Fig. is a view similar to Fig. 4- showing a further modification.

Referring to the drawings more specifically, reference numeral 10 indicates a water reservoir of any suitable material, such as glass, and situated at about six or eight feet above the floor to produce a proper pressure at the nozzle. Numeral 11 refers to the double nozzle, which is shown on an enlarged scale in Fig. 3. This nozzle comprises an outer tube 12 having one end tapered and closed as at 13. while the opposite end is open.

as at 14. A delivery tube 15 passes through the side of the tube 12 above its open end,

extends along the axis of tube 12, and is oined: to the inner wall of'tapered end .13

att16. The end 13 is pierced with apertures ing thereacross, and connected to the drive motor 23..

When this irrigatoris in use the motor revolves the interrupter valve, thereby periodically interrupting flow through feed-line 19 and causing pulsating discharge from the dehvery nozzle. The speed ofthe motor canbe suitably controlled to govern the du ration of the pulsations.

In the species shown in Fig. 4 the force of the discharge-is derived from a power pump instea'diof from gravity feed. This species is illustrated ashaving a single nozzle 24, although obviously it may'have a double nozzle as in Fig. 1 if desired. The feed line ex-- tends fromthe-nozzl'e to the reservoir 26, and

the forcepump 27 is interposed in the feed line. The pump 27 is a single acting plunger pump with check valves 28 arranged so that the pump draws liquid from the reservoir and forces it toward the nozzle. The. crank arm 29of. the pump is operated'by a gear wheel 30 which carries a plurality of crank pin holes 31 distributed along: its radius to provide means for varying the length of the stroke of the pump. Wheel 30 is moved by. a motor 32 through worm. 3.3,. and the.- variable resistance 34 provides meansfor varying both the frequency and intensity of the pulsations delivered by the nozzle. 7

In the species of Fig. 5 the pump 35 is driven by a motor 36 through reduction ears 37 and 38. The valve arrangement is similar to that of Fig. 4 but a by-pass 39 leads from the delivery chamber 41. A screw valve 42 controls the amount of liquid delivered through the by-pass. This apparatus is provided with a double nozzle similar to that shown in Fig. 1. In this device the screw 42 may be adjusted While the pulsator is Working to regulate the pressure and volume of Water delivered by the nozzle.

I claim:

1. An intestinal irrigator comprising a nozzle adapted for insertion into the intestines, a source of liquid supply, a feed line connecting the nozzle to the source of supply, a reciprocating pump in said feed line to cause a pulsating delivery from the nozzle, and means for regulating the stroke of the pump to vary the amount of Water delivered at each pulsation.

2. An intestinal irrigator comprising a nozzle adapted for insertion into the intestines, a source of liquid supply, a feed line connecting the nozzle to the source of supply, a reciprocating pump in said feed line to cause a pulsating delivery from the nozzle, and means for regulating the speed of the pump to vary the rate of pulsation.

3. An intestinal irrigator comprising a nozzle adapted for insertion into the intestines, a source of liquid supply, a feed line connecting the nozzle to the source of supply, a reciprocating pump in said feed line to cause a pulsating delivery from the nozzle, said pump being provided with a bypass connecting its delivery chamber to its inlet, and adjustable means to regulate the amount of flow through the by-pass to thereby vary the volume of liquid and the force of each pulsation.

4. An intestinal irrigator comprising a nozzle adapted for insertion into the intestines, a source of liquid supply, a feed line connecting the nozzle to the source of supply, a reciprocating pump in said feed line to cause a pulsating delivery from the nozzle, means for driving the pump at a uniform speed, a by-pass forrelieving part of the pressure in the delivery chamber of the pump, and means operable While the pump is Working to regulate the flovv through the by-pass to thereby vary the volume of liquid and the force of each pulsation.

5. An intestinal irrigator comprising a nozzle, adapted for insertion into the intestines, a source of liquid supply, a feed line connect-- ing the nozzle to the source of supply, and a motor driven reciprocating pump in said feed line, said pump being adapted to cause a pulsating delivery from the discharge nozzle.

In testimony whereof I altix my signature.
