This invention relates to devices for irrinozzle and then the valve. By reference to gating cavities of the body, particularly Fig.2 and its associated cross sectional views, 55 natural cavities, such as the colon, and has it will be seen thatthe nozzle consists of an for an object to provide a unitary nozzle elongated hollow body, 19, having an orifice,
structure adapted to pass fluid to the. upper 20, near its end. This may be termed the or inward portion of the cavity and to withcolon tube portion as it is intended to exdraw the fluid and matter washed from the tendlinto the inner or upward portion of the 60 cavity at a lower or less remote portion; a colon when the device. lsused in the treatfurther object is to so control'the supply and ment of that part. The orifice, 20, is pridischarge that these functions may proceed marily intended to supply the irrigatin or concurrently, or'the discharge may be remedicating fluid, but may also be use as versed and take lace through the upper supan exit for withdrawing fluid or permitting 65 ply orifice, or t e supply may be directed its escape. Two tubes, 21 and 22, are shown through the discharge and the exit orifice for merging intov the body portion, 23, of the breaking u or dislodging bodies of solid structure which is larger circumferentially matter ten ing to delay the discharge by than the nozzle and contains a partition, 24 clo ging the exit orifice. dividing it interiorly into-two ducts, and

It is shown comprisbe supplied by gravity from a fountain ing a casing, 30, which in many instances will; 1 syringe bag, 15, and discharge at, 16, to some be made of hard rubber, which casing is' convenient receptacle. The liquid is led shown as being substantially cylindrical andv 00 from the container, 15, by means ofa tube, having two tube connctors, 31 and 32, at one 17, and to the nozzle, 18, through a valve, side and two tube connectors, 33 and 34, at 30; For a better understanding of the. inthe other side. These connectors 'are'shown vention I shall first describe in detail the disposed in the sameplane horizontailyflof the valve body,
the valve or in a plane substantially at right angles to the axis of the valve seat and the rotation of thevalve body, 35. This valve body is shown formed with three transverse openings, see Fig. 10 and designated b the reference characters, 36, 37 and 38. en 35, is in position in its seat in the case, 30, these openings, 36, 37 and 38 are disposed in the same plane as are the tube connectors, 31, 32, 33 and 34. The inside of the casing is shown formed with a groove,
39, having a series of indentations, 40. This is for receiving a detent illustrated as a spring pressed ball, 41, for holding the valve body at its various positions of adjustment. The valve body is so held in the casing that it may be readily removed and replaced for the purpose of permitting cleansing as oocasion requires.
When the valve is set at the position shown in Figures, 6, 7 and 10, and the device is set up generally as illustrated in Figure 1, the liquid flows from the bag, 15, by the tube, 17 through the connection, 31, passage, 36, connection, 33, tubes, 21 and 25, into the bore, 29, and out of the orifice, 20, and into the cavity of the body being treated. It then returns with whatever matter it may have dislodged through the orifice, 27 conduit, 26, tube, 22, connection, 3i, conduit 37 connection, 32, to the discharge afforded by the tube, 16, i
When it is desired to use only the single end of the nozzle the valve is set up in position and the nozzle is only inserted far enough to execute the desired treatment and in such position that the discharge will not talre lace through the orifice, 27. \Vhen it 1s esired to drain from the upper end of the nozzle and through the orifice, 20, the
valve is set in the position illustrated in Fig. 12. In this position the fluid passes througn the orifice, 20, bore, 29, and tothe centermo'st conduit. 38, going from the tube con nection, 33, to thetube connection, 32, and out through the discharge 16.
Sometimes it may be desirable to flush the discharge tube for the purpose of cleaning it or to remove particles of matter which accumulated at the orifice, 27, in which case the valve is set in the position illustrated in Fig. 13. In this instance the flow of liquid goes through the tube connection, 31, the central conduit, 38, and out to tube connection, 34, passing through tubes 22-26, and out through the orifice, 27 After but a brief connection of this kind the matter will probably be dislodged or broken up and the operator will then set the device at the Figure 10 position, whereupon the normal irrigational flow will be continued.
The shut-oil position is illustrated in Figure 11 as will be obvious.
