Among the objects which `the present inventionhas in view are: to.' visibly indicate the flow'conditionv of liquid used'for internal treatment; to .provide Ian automaticcontrol vfor -the` flow vof liquid used ininvisible locations, or where the delivery end ofthe flow-,promotingmeans cannot be seen; and to--provideadetector adapted tofshow the condition of fluid intermediate the supply reservoir thereof and the point of application. i

Figure 1 is a vertical section of a regulator constructed and arranged in accordancewithv t-he present invention, and fragments yof other apparatus used in connection therewith shown and attached thereto.

Figure 2 is a similar view of a regulator showing the same as in the inactive condition thereof, the flow'having vbeen arrested by conditions in the delivery pipe. v

Figure 3 is a cross section of the regulator, the section being taken on the line y3--73 in Fig. 2.

W'hile the device herein disclosed is adapted for use in a great many installations, 'that principally relied upon by me is the use as a visible gage or detector to show the condition of the flow in the delivery tube 8 used in the practice of colonic therapy. When thus employed the tube 8 is introduced through the rectum to the intestines ofthe person being treated and isk of sufiicient length to extend into and through the descending colon and into the ascending colon and the intervening intestinal tract.

The tube 8 has orifices `9 adjacent the forward tapered end 10 thereof. The orifices 9 are preferably disposed in staggered relation for the purpose of delivering fluid to the intestinal tract to locally dilate the intestines so that the tube may be advanced therethrough or through Aany sphincter therein. Itis obvious that in this operation the tube may become bent Aor votherwise -strangulated,-or the pressure incident tothe dilation of the local portion of the intestines may exceed that which it is desired to employ, and in these events the flow of the liquid from the goose-neck 11 will be arrested, or the spray or spout of the fluid will visibly decline.

A fluid reservoir or container 12 is disposed at any suitable height above Vthe point of application for which the fluid is destined. A flexible hose 13 connects the reservoir with a clear glass receiver 14 within tively connected with the tube 8.

The lower end ofrthe '1f-receiver '.14 is connected byfa flexible pipe 16 with a valve casing 17 wherein is mounted a rotary valve 18 and operable by vmeans of a handle 19. The lower end of the valve casing 17 is opera- Wh'en in operation and after the tube 8 vhas been partially inserted, the attendant opens the valve 18 to let the fluid flow from the receiver 14 through the tube 8. The

receiver 14 is at all times in open communication `with the reservoir 12 through the goose-neck 11. Y vAny fluid in the reservoir 12 will flow fromthe goose-neck 11 in the forml of a fountain as indicated in Fig. 1, so long as the pressure in the receiver 14 is below the pressure on the fluid in the goose-neck. This indicates to the attendant a clear and unresisted passage in the tubey 8. When, however, the resistance toy the exit ofthe fluid from the tube 8 or through the tube 8, the fluid delivered `from the goose-neck 1 1 being in excess of that flowing v vfrom the receiver 14 increases the water content in the 'receiver 14 as indicatedjin Fig ,ure 2 of the drawings. Ast'he fluid content increases in the receiver 14, the air pressure v in the upper end'of the receiver increases until it overcomes the pressure on the fluid in the goose-neck 11. When and asv the pressure overcomes the flow from the gooseneck, the attendant is made aware of the stoppage condition in the tube 8 or intestinal ytract yunder treatment, beingy thus apprised of the condition he is supposed to take steps to relieve the condition.l This is' accomplished byk using an apparatus set forth in a Patent Reissue No. 16,251, which ,was granted to me on January 12, 1926.

By thus providing a visible means for determining the rate and extent of pressure of the fluid inits delivery, enables the attendant to prevent and relieve painful conditions which might otherwise arise in such treat-y ments.

Claims:

1; In combination with a liquid yreservoir and delivery tube therefor, a visible indi- -cator disposed between said reservoir and tube for disclosing the condition of the flow through said tube7 said indicator embodying a transparent receiver operatively connected with said reservoir and said tube in kopen communication therewith, and aninlet inember extending part-way into said receiver for delivery thereinto, said receiver being closed at the upper end of said inlet memA ber to '.torin an air pressure chamber, the

pressure wherein is increased or diminished in accordance with the accumulation in the endof said receiver opposite said inlet member, said pressure being employed to restrict and stop the. flow from said inlet member.

2. In combination with a liquid reservoir and delivery tube-therefor, a visible indicator disposed between said reservoir and tube for disclosing thecondition of the low through said tube, said indicator embodying a transparent receiver operatively connected with said reservoir and said tube in open communication therewith, the delivery end ot' said member being bent to deliver liquid therefrom in a vertical direction within. said receiver, the upper end ot said receiver being closed to iorin an air pressure chamber, the pressure wherein is adapted vto correspond with the accumulation of liquid inthe delivery end of said receiver, whereby the flow from said member is graduated and terf minated in accordance with said accumulation.' 1
