STACK ENEMA APPARATUS Jan. 16, 1951 2 Sheets-Sheet 2 Filed March 4, 1947 INVENTOR. 1 J'Tac/r Patented Jan. 16, 1951 UNITED STATES PATENT OFFICE v 2,538,215 ENEMA APPARATUS Mary E. Stack, Seattle, Wash. Application March 4, 1947 Serial No. 732,302

This invention relates to apparatus for use in connection with administration of enemas or othor internal baths or irrigations.

While administration of an enema is a necessary treatment in probably a majority of cases of sick people, yet enema apparatus now in practical use has not been improved for years.

Prior art apparatus employed in this particular field generally comprised a water bag, tube, and a hose connection between the water bag and the tube. A difliculty in such prior art apparatus was that pressures were built up within the patient and need of relief therefrom necessitated the interruption of the enema and then it was necessary to start the enema all over again after discharge of gas, liquid, and fecal matter.

Also prior art enema apparatus was not of a design so that adequate and painless enemas could be given. It is an object of my invention to provide an improved appliance for use in giving an adequate and efiicient enema which will at the same time make the application of medi cated solutions in the colon less painful and more effective because of less pressure on delicate tissues. Properly trained personnel with the use of this apparatus can readily give an effective enema without causing pain, distension or overloading of the colon.

It is a further object of my invention to provide apparatus which will readily permit the giving of an adequate enema even in cases where a colonhas static ataxia, poor muscular action and is lazy.

Other objections found in the prior art included the use of a single tube and the absence of inlet and discharge opening in a tube which tube could be left in the colon of a patient at all times during the enema or other internal irrigation treatment. 1

It is anobject of my invention to provide a tubular member which can be inserted in the colon of a patient and which can be maintained there at all times during the enema or other internal irrigation treatment.

It is a further object of my a receptacle 'for clean or fresh treating solution (hereafter called clean can) a receptacle for slightly soiled treating solution (hereafter called invention to. provide soil can) and a third receptacle for containing liquid and other matter which isnot again tobe used (hereafter called discharge can).

It is a further object of my invention to provide valve means disposed between the various mentioned cans and the tube which is to be inserted into the colon of a patient so that anyone 6 Claims. (Cl. 128-227) of a plurality of positions can be selected during the treatment of the patient. As the selected medicants which are added to provide the original treating solution from no part of the present invention, they will not be discussed. However any treating solution desired by the physician or nurse can be readily administered by th apparatus of my invention.

The various predetermined positions which may be selected will be discussed hereafter in detail; however, a normal operating position of structure embodying my invention, is to provide for free passage from the clean can to the patient and free passageway from the patient to the soil can.

Another object of my invention is to provide a position so that immediate gas relief can be provided for the patient at all times without requiring removal of the tube from the patient.

Another object of the invention is to provide auxiliary pressure providing means so that, when necessary, auxiliary pressure can be providedto stimulate the organs involved so that free flow of liquid-is possible.

Another object of my invention is to provide apparatus having suitable indicia so that the operative positions of the several parts'are readily apparent.

Another object of my invention is to provide apparatus which may be readily sterilized.

The above mentioned general objects of my invention together with others inherent in the same are attained by the device illustrated in the accompanying drawings throughout which like reference numerals indicate like parts: I

Figure 1 is a somewhat diagrammatic view in elevation and with parts broken away illustrating the apparatus of this invention; 7

Fig. 2 is a detached elevational view of the valve looking in the direction of broken line 2-2 of Fig. 1; 1

Fig. 3 is a sectional view with parts in elevation, taken substantially on broken line 3--3 of r represents one valve setting and wherein the view to the left in each figure is taken substantially on broken line y-y of Fig. 3 and the view to the substantially on the clean can It can always be maintained above any liquid level in the soil can i l. On the average, the maximum capacity of a patient for liquids during an enema is about 3 pints and thus the volume capacity of the soil can i l, below the floor of the clean can 53, may be slightly over 3 pints and thus at all times the liquid level in the soil can M cannot reach the liquid level inthe'clean can [3. Clean enema treating solution is first inserted in the clean can 13 and passes via conduits I6 and 2! to the colon of a patient. Soiled enema treating solution passes from the colon of the patient via conduits 22. and It to the container [4 for soiled enema treat-ing solutions. Due to the capacity of the soiled can M- below the floor level of the clean can solutions can flow from the clean can it through the passageways mentioned and to the soiled can it. We always have, because of the construction mentioned, a tendency of the liquids to flow in the direction mentioned. However, as the levels of liquids in the cans l3 and Hi approach each other, the difference in headbetween the liquids in cans i3 and M diminishes and a tendency to flow ceases. However, because of the volume capacity of the soiled can it belov. the clean can it there is a tendency of liquids to flow from can [3 to can 14 until the liquids approach a common elevation and the differential in head is eliminated. Obviously, there is no tendency, in View of the construction mentioned, for liquids to flow from the soiled can i i toward and into the clean can IS.

The valve-member, indicated generally by M5, is connected by flexible hose members it and i? with the clean and soil cans i3 and It. The valve member [5 comprises an outer casing [8 having a hanger l9 so. that. the valve member #5 may be suitably supported in suspension at any desired elevation. The hanger i9 is connected toany fixed support such as support as. Also the clean and soil cans l3 and M are provided with any suitable means (not shown) so that they can be adjustably supported by a fixed supporting means at any desired elevation above the valve member [5.

The valve member i5 is provided with suitable nipples so that flexible hose. members it, H, 2!, 22 and 23 are connected respectively with ports 24,. 25, 26, 2'5 and 28 respectively in casing. l8. Disposed between port and flexible hose 2| is a rubber bulb 29 and disposed between port 2? and flexible hose 22 is another rubber bulb 3@. These rubber bulbs are of the usual type which upon squeezing the same provide additional air pressure in the flexible hoses 2i and 22 depending of course upon the particular bulb which is squeezed. As these bulbs 29 and 3t are of the common type which are used in connection with syringes; they are not illustrated in detail nor are they further described as such is believed sufficient for those skilled in this art. The hoses ill and 22 connect with a tube 3| which is to be inserted into the colon of the patient and which is shown somewhat diagrammatically in Fig. l and is shown on a larger scale in Fig. 5. The flexible hose 23 is connected to the discharge can 32.

Referring now in more detail to the valve member I5 (see also Figs. 6 to 12 inclusive), the ports 2 and are in casing it and are diametrically opposite and likewise ports 25 and 2"! are in casing it and are similarly alined. The sleeve member 33 has ports 3 3 and 3% which are diametrically opposite and which can be moved into and out of alinement with the ports 2 and 2%.

Also said sleeve has ports 35 and 37 which are diametrically opposite and can be moved into and out of alinement with the ports 25 and 2?. Also the sleeve 33 has ports 38 and 39 (see Fig. 4 and also the view to the right of each of Figs 6 to 12 inclusive) and these ports 38 and 39 can be moved into and out of alinement with the ports 25 and 2 5. The port '10 in the end. wall of sleeve member 33 is movable into and out of alinement with the port 28 in the casing [8 (see Figs. 3, i and views to the right in Figs. 11 and 12).

A barrel ll has a plurality of passageways which are adapted to be moved into and out of alinement with the various ports in sleeve member 33. At the level of the ports 34 and 36 in the sleeve 33, inter-connected passageways 42, and l i are provided in the barrel 4|. The passageway M is of much less diameter than the passageways iii! and 43' and is designed for a controlled trickle of liquids therethrough and for purposes hereinafter more specifically mentioned. At the level of the ports 35 and 31 in the sleeve 33, through passageways iil and 416 are provided and also is provided a passageway 47 inter-connecting with said passageways 45 and Mi. Passageway 571A connects to passageway 45 and need not be of as large a diameter as the other passageways. Passageways 35, 56, MA and i are connected with passageways 4S and 4e. Passageways 43 and 4 9 may be moved into and out of registration with port fill in sleeve member which in turn may be moved into and out of registration with port 28 in casing IS.

The sleeve member 33 is rotatablymounted' in the casing 48 and in turn the barrel 4| is rotatably mounted in the sleeve member 33. The said sleeve member 33 has independent means to rotate it and likewise the barrel 3! has independent means to rotate it. As illustrative of a means to rotate the sleeve member 33, pins or projections 56 (Fig. i) are carried by the sleeve member These pins or projections 53 inter-fit in openings 5! in plate 52. The plate 52 has a hub integral therewith and the hub 53 is mounted for rotary movement on a shaft 54, which said shaft is integral with the barrel 41. Thus the sleeve plate 52 and hub 53 are mounted for relative rotary motion as respects the barrel ii. Means to permit ready rotation of the hub 53 and in turn the sleeve member 33 are provided by a thumb lever 55 which may be threadedly inter-connected with a bore 56 in hub 53.

an illustration of means to provide ready rotary adjustment of the barrel 4!, the shaft 58- is provided with a squared portion 5? and a mating squared opening 58 in lever 58. Nut means is of a size to be detachably secured to the threaded portion Si or" the shaft es.

In order to assemble the parts from that shown in exploded relation in Fig. 4, the sleeve member 33 is inserted into the bore of the casing l8. Then the barrel 4| is slidably inserted into the sleeve member 33. Then the plate 52 is inserted in place with the openings 5| thereof registering with the pins or projections 50 carried by the sleeve member 33. Then the cap 62 is threadedly engaged with the threaded portion 63 of casing l8. Next the lever 55 is threaded in the bore 56 of the hub 53. Then the lever 53 is inserted in place with the squared opening 58 thereof registering with the squared portion 51 of the shaft 54. Then the nut means 60 is tightened and all parts are held in the position shown in Fig. 3 of the drawings.

As will appear in Fig. 2 of the drawing, the portion 54, of the lever 59, can be caused to register with the numerals or other appropriate indicia means, as 1 to 5 inclusive, which indicia are on the radially outer portion of the cap 62. The notch 65 registers with suitable indicia means radially inwardly on the cap 62, as indicia means 1 to 3 inclusive: open, emit gas, and shut. Thus the radially inward indicia means indicate the position of the sleeve 33 and the radially outward indicia means indicate the position of the barrel The tube 3 I, indicated generally in Fig. 1 of the drawing and shown more in detail Fig. 5, is provided with an inlet opening 66 and a plurality of discharge openings 61. I Preferably the inlet opening 66 is at the end portion as indicated and preferably the discharge openings 61 are on the sides as indicated. Thus the muscles and tissue of the colon will not tend to interfere with the inlet of liquids via inlet opening 66, and upon distension of the colon then the openings 61 will be available for discharge of liquid, gases or fecal matter.

The tube 3| may be first inserted in the colon of a patient and then the clean can I3 and soiled can M as well as the valve are moved to suitable elevations above the patient with the valve members in the position shown in Fig. 6 of the drawings. There is no flow of liquid past valve 'as all ports are closed. Thus the desired treating solution may be placed in clean can [3 either before or after the tube 3| is inserted in the colon of the patient. Due to the fact that I have provided for a discharge via openings 6'1 very little head is required to cause liquid to flow from the clean can l3 into the colon of a patient. In other words by being able to provide for the entrance of liquid and discharge of gases and prevention of building up pressures Within a patient, then the liquid may be caused to enter a patient and with very little head. As soon as there is a muscle relaxation, the liquids tend to flow with little or no head as apparently atmospheric pressure is greater than the internal pressure within a patient. Also movement of the diaphragm of the patient apparently changes the internal pressure and the liquid in either clean can he or soiled can l4 tends to rise and fall with the diaphragm movement of the patient.

By providing a device where I can cause the liquids at a minimum head to flow to the patient, then I can wait until there is sufficient relaxation of muscles or sufii-cient diaphragm movement so that the liquids tend to move inwardly into the patient.

Also if the muscles are tense and do not tend liquid from inlet opening 66. Similarly if fecal matter tends to block the discharge openings 61, then to stimulate flow, the bulb 30 may be squeezed. Of course when either bulb 29 or 30 is squeezed the valve should be closed so that all of the air pressure provided by squeezing of the bulb is in the tube 2| or 22 and does not pass out through the valve l5 to the atmosphere or to any of the particular cans involved. The various foregoing matters have been considered at this point as they are useful in determining the relative elevations of the cans I3 and I4, the valve I5, and the patient.

The position of the valving parts as indicated in Fig. 6 of the drawing is such that solution will not flow either to or from the patient and may thus be considered an initial position, and thus the apparatus is ready for manipulation to provide the desired treatment. When the parts are in the relative positions shown in Fig. 6 of the drawings, then the portion 64 of the lever 59 registers with the numeral 1 and the notch 65 on the hub 53 registers with the numeral 1 or op n The normal positions of the parts during through registering port 26 in casing l8, through hose 2 l, and out via inlet opening 36 in tube 3| to the colon of the patient. At the same time discharge from the patient to the soil can I4 is possible via discharge openings 6'! in tube 3 I, through hose 22, through port 2'1, through registering port 31, through registering passageway 45, through registering port 35, through registerin port 25, and thence via hose IT to soil can l4. There is no connection to the discharge can 32 as passageways 48 and 49 are--not in registration with either port 28 or port 48. In Fig. 7 of the drawings, ports 28 and 43 are in registration and thus only the upper port as viewed in the drawings, namely port 43, is numbered.

During the normal position of the apparatus as indicated in Fig. '7 of the drawing, liquids tend to flow from the clean can I3 into the colon of the patient and in due course the liquids then tend to leave the colon and rise in the soil can l4. If during treatment it becomes desirable to discharge any material which may enter the soil can l4 and deliver the same to the discharge can 32, the valving parts can be changed to the relative positions shown in Fig. 8 of the drawings. In this position the portion 54 of the lever 59 registers with the numeral 3 and the notch 35 on the hub 53 registers with the numeral or the indicia open. In such position, there is no flow between the clean can I3 and the patient as the barrel 4| blocks any flow between ports 34 and 35. At the same time discharge from the soil can M to discharge can 32 is permitted, as a liquid may flow from soil can l4 via tube I1, through port 25, through registering port 35, through registering passageway 41, through port 49, through registering port 40, through registering port 28, and thence via hose 23 to discharge can 32. At the same time liquids from clean can |3 are blocked from entering hose 2| as the bars rel 4| blocks the ports 35 and 31, Y

It it becomes desirable during treatment to lower the back pressure caused by the elevation .of soil can It, or if it should be desired to use the treating solution only once, then the valving part can be moved to assume the relative positions shown in Fig-9 of the drawings. In this position the portion 54 of the lever 5% will register with'numeral 4 and the notch 85 will register with the numeral 1 or open. In this position liquids from the clean can I3 flow via tube it, through port 2:1 in casing it, through registering port 34 in the sleeve 33, through registering passageway 43 in the barrel 4|, through registering port .38 in the sleeve 33, through registering port 2B,through hose 2| and out via inlet opening 2% in the tube 3! to the colon of the patient. At the same time discharge from the patient to the discharge can 32 is possible via discharge openings 61 in tube 3|, through hose 22, through port 27, through registering port 31, through registering passageway 56, through passageway 18, through registering port 0, through registering port 23, andthence via hose 23 to discharge can 32. At the same time liquids may flow from the soil can I l to the discharge can 32 via tube ll, through port 25, through registering port through registering passageway .16, through passageway 33, through registering port iii, through registering port 28, and thence via hose 23 to di charge can 32.

During treatment it is often desirable to provide a dribble or trickle flow of liquid from the 7 clean can it to the patientand to provide for a gas escape from the patient to the discharge can 32. Atmany times the dribble or trickle stream will be such. that it will be absorbed by the tissues of the patient and merely gas will ilow from the patient to the discharge can 32. Also at times there may be a slight discharge of liquid as well as gases from the patient to the discharge can 32. In such position the valving parts will be in the position shown in Fig. .10 of the drawings. There will be a connection from the clean can E3 to the patient and a connection between the patient and the discharge can The soil can 54 will not be connected to any other can or to the patient. In such position the portion of the lever 55 will register with the numeral 5 and the notch 65 will register with the numeral 1. or open. In such position liquids from the clean can 53 flow via tube it, through. port through registering port 3 1 in sleeve 33, through registering passageway l in the barrel d i, through regis tering port 556 in the sleeve 33, through registering port 26 in the casing i3, through hose 2 i, and out via inlet opening 66in the tube l, to the colon of the patient. At the same time discharge from the patient to the discharge can 32 possible via discharge openings fi'i in tube 35 through hose 22, through port 23', through port ill, through regiotering passageway l'lA, through 1" ageway 515, through registering passageway through par tially registering port it, through registering port 28, and thence via hose 23 to discharge can if during treatment it becomes desirable to have an emergency relief of gas and this without any connection betweer the clean can. and the patient, this be obt ed by the relative positions of the valving par to as shown in In such position the portion of the lever 59, registers with thenuineral 2 and the notch l registers with the. numerals or with emit gas. In this position gas mayflow from the patient through openings 6'? in tube 8!, through hose 2?, through port 21, through registering port 3i,

through passagewaytdthrough registering port 3'5, through registering port 25, and thence via hose ii to soil can I l. In this position there is no connection between the patient and clean can iii. There is a small discharge possible from the patient to discharge can 32 as gas in passageway enters passageway 49, thence port 40, thence port 28 (ports All and 2'8 are overlapped) and thence through hose 23 to can 32.

If during treatment it is desired to remove the barrel H and yet at the same time to maintain all ports closed, this can be accomplished by turning the Various valving parts to the positions shown in Fig. 12 of the drawing. This position accomplishes all of the purposes of the position shown in Fig. 6 but the additional purpose of permitting removal of the barrel 4|. In this position the sleeve 33 blocks passageway between ports Z l and 26 and also between ports 25 and 21. The ports .28 and 48 may or may not be in registration and hence there may or may not be communication between the valve and the hose 2%. As the discharge can 32 is below the valve I5, ports 28 and ill need not be out of registration to prevent now from discharge can 32 to valve IS. The parts assume the relative positions of Fig. 12 with portion at of lever 5E3 registering with any numeral (in Fig, 12 it registers between numerals 2 and 3) and notch registers with numeral 3 or shut. In other words, sleeve 33 has been angularly moved to block passage between hoses I6 and Bi and between. hoses l1 and 22 regardless of the position of barrel. M. Thus during operation of the apparatus the barrel ll can be moved for cleaning processes and then re-inserted after being cleaned and the process can be again resumed without the necessity of draining liquids from the apparatus.

From the foregoing it is obvious that .I have provided apparatus so that desired medicated solutions can be used in enemas and the same can be placed in. the apparatus before or after a tube is inserted into the colon of a patient. The tube of my invention is provided with both inlet and outlet means so that the incoming solutions can displace gas and obviate the building up of air or gas pressures or permit the release of any such if they are built lip without interruption of the treatment. This is of substantial value as the liquids may gradually enter the patient and with very little head so that the muscles of the patient can gradually relax and there will be a gentle inward flow of treating solution to the patient and a gradual discharge of solution and material from the patient. This flow, in many instances, follows the diaphragm action or the patient and has not occurred. in prior art apparatus where we merely have an inflow of liquids and inherent compression of air or gas in the patient to permit such inflow of liquids. Inflow of liquids, without gas or air relief means to keep pressures down, results in stimulation of organs and muscles and counteracts any tendency oi." the diaphragm action to cause liquids to have a modulated and gentle inflow and outflow.

Next the apparatus permits disposal of any used solutions and their replacement without removal of the tube from the patient or the reuse of treating solutions.

Next the apparatus permits treating liquids to be used only once, when desired, and with aminimum back pressure to their discharge.

Next the apparatus permits a regulated minimum inflow of liquids which will either gradually add to the supply of treatingliquids or merely supply enough liquids to replace liquids absorbed by the body. At the same time the apparatus permits gas discharge and at a minimum back pressure.

Next the apparatus provides for an emergency gas relief which may be needed and again with-- V nection of the same;

Next the apparatus is provided with air pressure providing means to stimulate inflow and/or outflow from the patient.

Obviously changes may be made in the forms, dimensions, arrangements and manipulations of the parts of my invention without departing from the principles thereof as defined in the claims of this application.
