' NOZZLE Filed July 27, 1935 Patented Feb. 21, 1939 UNITED STATES PATENT OFFICE NOZZLE Rodney S. Kennison, Los Angeles, Calif. Application July 27, 1935, Serial No. 33,448

My invention relates to improvements in colonic apparatus, the primary object being to provide means by which the colon or vagina can be most effectively and safely irrigated. More particularly this invention provides improved features over the disclosure set forth in my companion application'Serial Number 721,117, filed April 18, 1934, for Irrigating tables. The present application is directed more particularly to the construction of the applicator used with my improved apparatus. invention is to. provide a double flow applicator for-insertion in the rectum, vagina or other orifice, whereby the inflow of irrigating liquid under positive pressure and the outflow of liquid and waste under negative pressure can be simultaneously or independently controlled in a most efficient and effective manner. A further object is to provide an applicator in which the outer wall can be regulated and maintained at a most effective temperature by the liquid flowing from the source of supply, whereby the rectal sphincter muscles are caused to relax if the liquid used is hot or to contract if the liquid is cold, when the applicator is used for administering colonic treatments, or to treat muscle fibers or tissue in a similar manner when the applicator is used in connection with other orifices. Another object is to provide means for automatically holding the applicator inserted in the orifice at the desiredv depth, and among still further objects is to provide means for preventing the stoppage of the outflow duct or ducts in the applicator by feces.

To these ends my invention comprises the features of construction and combination of parts hereinafter described and claimed.

In the accompanying drawing forming part of this specification, Fig. 1 is a diagrammatic view of a portion of my improved colonic apparatus showing my improved applicator by which irrigation is applied to a patient; Fig. 2 is a longitudinal section of my improved applicator, and Fig. 3 is a longitudinal section of an alternative construction of my improved applicator.

My improved applicator D for insertion in the anus and rectum, or in the vagina, or other orifice. resembles a barrel having inner and outer thin cylindrical shells 56 and 5|, spaced apart and connected together near one end of the structure and shaped with a reduced blunt forward end 52. The forward end of the inner wall is closed while the corresponding end of the outer wall is perforated at 53 for the egress of liquid from within the space or channel between the The primary object of my" 4 Claims. (Cl. 128-240) walls. The rearward end of the barrel is corrugated at 54 and forms a nipple leading from the main longitudinal outflow duct 65 through the barrel to receive and hold the flexible tube leading to the sewer connection 55 or other duct. 6' A radiating annular hollow guard 56 is connected with the channel between walls 50 and 5| at the rearward end of the structure and serves to limit the insertion of the barrel in the rectum or other orifice, also by nipples 51 and 58 connected there- 10 to flexible ducts such as 33 can be attached for conducting different kinds of irrigating liquid, varying in quality and temperature when desired,

to the colon or other orifice. When desired only one nipple with corresponding connection is used, 16'

while in Fig. 1, two separate supply tanks 59 and 6|] are illustrated to which valved ducts 6| and 62, leading to the applicator are coupled by the nipples 51 and 58, thus enabling the operator to employ irrigating liquid from either or both 20 tanks and at suitable temperatures to control the temperature of the liquid in the jacket of the applicator. The annular groove 63 in the outer shell 5| of the barrel near the guard 56 is adap ed to receive the anus or sphincter muscles which 5 automatically assist in holding the barrel inserted in the rectum at the desired depth. Orifices 64 entering the main or egress duct 65 within the inner shell 56 of the barrel admit fecal matter and irrigating liquid from the colon or other orifice into the main longitudinal duct 65 within the inner shell of the barrel from whence the same is conducted to the sewer or waste receiving receptacle, not shown. Perforations or ducts of any desired type and number around each orifice 64 allow flushing liquid under pressure to prevent fecal matter from clogging the orifice.

When desired, the barrel of the applicator (see Fig. 3), can be constructed with a single cylindrical wall or shell 66 having a solid annular guard 61 and outlet orifice such as 68. In such event the irrigating liquid can be conducted through the closed reduced outlet end 69 by the small tubular duct ll. Thus the dimensions of 45 the applicator can be minimized so that the applicator is better suited for use with infants.

In use my improved applicator is inserted tip first into the orifice to be treated to a depth limited by guard 56 or when the applicator is used for colonic irrigation so that the anus or rectal sphincter muscles engage in the annular groove 63 and automatically hold the applicator inserted. Flushing liquid of the desired kind, pressure, temperature and amount enters the orifice through 55 opening 53 in the tip of the outer shell from the valved supply ducts BI and 62 or any suitable source of liquid supply such as tanks 59 and 60. While thus applied the temperature of the outer shell of the jacket produced by the flushing liquid received from the source of supply causes the rectal sphincter muscles and any tissue in proximity to the outer surface of the outer shell to relax and stimulate circulation if the supply of flushing liquid is hot or to contract and reduce fever if the supply of flushing liquid is cold. In this manner the applicator is adapted to treat the rectal sphincter muscles and tissue effectively and at the same time through valved control to conduct inflow and outflow simultaneously or in dependently which is an advantage. After or during irrigation, according to whether or not the outflow is opened or closed the outlets 64 permit the contents of the colon, vagina or other orifice to evacuate through the longitudinal passage 65 in the applicator. During this operation the force of the flushing streamlets through perforations 10 in each outlet 64 prevents fecal or other waste matter clogging the outlets.

In accordance with the patent statutes, I have described the principles of operation of my invention together with the construction thereof which I now consider to represent the best embodiment thereof, but I desire to have it understood that the structure shown is only illustrative and that the invention can be carried out by other means and applied to uses other than those above set forth within the scope of the following claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A colonic irrigating applicator, comprising, a barrel having an outer cylindrical shell and an inner cylindrical shell spaced from the outer shell and forming an irrigating liquid transmitting channel therethrough, said liquid transmitting channel having an irrigating liquid receiving opening at the rearward end of said barrel and an outlet at the forward end of the barrel, said inner shell forming a main inner duct terminat-- ing in a coupling nipple at its rearward end and being closed at its forward end, and said barrel having an orifice through its side entering said main duct for conducting irrigating liquid and fecal matter from the colon, and an annular guard radiating from the rearward end of said barrel.
