Primary Examiner Charles F. Rosenbaum Attorney- Albert M. Zalkind ABSTRACT: The invention is particularly suited to comatose or incontinent patients who, having no control of bowel functions, are literally helpless in that regard and accordingly present a serious problem from the standpoint of cleanliness and nursing care. The structure contemplates a disposable article which comprises a plastic bag, the open top of which is secured to a ring of flexible material such as paper, plastic or textile, treated with a pressure sensitive adhesive so as to adhere between the buttocks ofa patient with the bag in position to receive fecal matter. A principal feature of the invention is the construction of the flexible ring whereby it presents an initially small aperture adjacent or surrounding the anus of the patient. However, during the process of defecation, as the sphincter expands, the ring likewise expands to increase the diameter of the aperture so as to ensure proper accommodation of fecal matter flowing therethrough into the bag and to ensure adherence of the ring to the patient. The expandability of the adhering ring is effected by providing plurality of pleats therein which are normally in folded condition, but which open during defecation. Further, the existence of the pleats effects venting passages so that gas released by the patient is vented and not trapped in the bag to cause ballooning or possible bursting.

FIG. 10
INVENTOR BLUMA MILLENBACH ATTORNEY U.S. PATENT 3,522,807 FECAL RECEPTACLE Briefly, the construction contemplates a ring of tough but flexible paper or other thin flexible material which has secured thereto, on one side, a plastic film bag in register with an aperture through the ring. The other side of the ring is coated with a pressure sensitive adhesive suitable for adherence to a patients skin and having a peelable layer of protective plastic film which can be removed prior to applying the device to a patient. The ring is provided with a plurality of radial folds or pleats clear of adhesive. The initial size of the ring is small when the adhesive area is applied to a patients buttocks with the aperture margin encompassing the anus.
The device can remain on the patient many hours in readiness to receive fecal matter. Owing to the proximity of the ring aperture to the anus, in substantial contiguity therewith, when the act of defecation causes radial enlargement of the patients sphincter, the ring is caused to enlarge radially. This is permitted by an expansion or unfolding of the pleats. As a result the aperture increases to a substantial extent, about twice the initial area, sufficient to accommodate passage of fecal matter.
Upon completion of defecation, the contraction of the sphincter effects general contraction of the ring and of the aperture to a relatively smaller size, thus minimizing back flow or escape of fecal matter. The pleated construction not only affords gas escape at all times but by allowing the ring to expand with the sphincter and the ensuing separation of the buttocks, radial pulling force on the ring is avoided which would cause or tend to cause separation from the buttocks.
A detailed description of the invention now follows in conjunction with theappended drawing in which:

FIG. I0 is a fragmentary elevation of a modified pleat formation in section; and
FIG. 1 l is a fragmentary view ofa modification wherein the pleat walls can be adhesively coated but prevented from adhering to each other, so as to ensure venting and expansion of the device.
Referring to the drawing, the construction is illustrated in FIG. I as asupport member 10 andreceptacle 12.Member 10 is comprised preferably ofa thin, tough flexible paper ring (FIGS. 2 and 3), which need not be more than two to ten thousandths of an inch thick, although greater thickness is usable. Thereceptacle 12 may be a conventional flat plastic film bag, of the ordinary side welded seam construction and having an open top expanded to be thermally welded to one face ofmember 10 in a conventional manner. Such combinations of paper and plastic bags have heretofore been known for ileastomy bags, etc., and accordingly there is no need to dwell on details of the methods for such welding.
Referring to FIGS. 2 and. 3,ring 15 is of planar sheet, or the like, material with integralradial tabs 18, a pressure sensitiveadhesive coating 22 on one face, with a peelable protectiveplastic film sheet 25 whic? registers with the ring and tabs to protect the adhesive surface in a well known manner. Thering 15 is provided wthv pleat means, e.g., pleated portions comprisingpleat walis 35a, 35b intermediateradial fold lines 28, 30, 32 provided as a set to effect a generally "V" or U" shaped fold orplea 35, affecting a crevice 36. Foursuch pleats 35 spaced apart are shown, but any suitable number can be used. The initial condition wherein the support member is contracted around a generallycentral aperture 38 is shown in FIGS. 1, 2 (solid lines) and 3; it should be particularly noted that the adhesive coating does not extend into the pleats. Thus, thering 15 can be expanded in its own plane whether that plane be flat, or, as would be the general case, curvilinear when applied to the buttocks of a patient as shown FIGS. 6 and 7.
The distortion of theaperture 38 as seen in FIG. 2 is, of course, due to the initially contracted condition, shown in solid lines. When, however, the ring is expanded, the aperture effects its die cut circular configuration as shown in phantom. Such initial distortion of the aperture is of no moment, and for that matter the four arcs of the ring periphery would likewise not lie on a true circle when the ring is contracted.
Theprotective sheet 25 may loop into the pleats as a manufacturing convenience, or may extend over the crevices 36; this is of no moment since the protective sheet is removed prior to applying the device and could not affect enlargement of the ring.
It is important to note that theadhesive coating 22 does not cover the area between the fold lines of the pleat walls as heretofore mentioned and as illustrated by the broken away portion A (FIG. 2), shown expanded. Thus, the ring can expand multidirectionally, i.e., radially and peripherally without being impeded, such enlargement ofaperture 38 being of the order of from approximately 1" when contracted to 1 1/2" expanded.
The pleat crevices 36 remain sufficiently open to permit gas escape therethrough in the initial contracted condition, thus serving as vents for the device after thering 15 is applied otherwise sealingly to the buttocks. This is of some importance. to prevent ballooning of the plasticfilm bag receptacle 12 which is secured as by thermal welding to the opposite and non-adhesive surface of the ring. Even when the ring is expanded venting can take place at the pleat areas since they are not adherent to the patient's skin.
The open top 40 (FIG. 2) ofthe bag is spread and folded inwardly being sealed to thering 15 at the interface 42 (FIG. 3) but looped around the pleats without covering the ends of the pleats so as not to block the venting effect. As indicated in the cut away area B of FIG. 2 the bag margin is suitably flattened and extends from edge of theaperture 35 to the periphery ofring 15. The natural furling of the bag and the looping a ound the pleats ensure the bag expanding at its open top asring 15 expands. The edges of the bag opening are suitably trimmed to conform to the circularity of the ring aperture.
An expanded view of an identical support member construction is shown in FIGS. 4 and 5, FIG. 4 being taken reversely of the viewing direction of FIG. 2but thebag 12 is secured with its open top flanged radially outward in FIGS. 4 and 5 as compared with FIGS. 2 and 3 wherein the upper margin of thebag 12 extends radially inwardly.
Whether the bag is of conventional flat construction or specially formed with a flange is, of course, a matter of design. lfa flat bag is used, theseams 45 may be oriented in any position, preferably intermediate the pleat areas. In any case. the upper margin of the bag loops around thepleats 35 and does not block vent passage.
Other modes of bag attachment are possible. For example, FIGS. 8 and 9 shows the open top of a circular bag folded to a generally square formation and the top folded inwardly to be secured to thering 15 at theinterface 48. Also, by suitable dies at crimping effect as illustrated by rabbet 51' andgroove 54 is achieved for augmented securement by heat and pressure in a well known manner.
In FIG. 10, a modified pleat is illustrated, the loop in ring being upwardly as compared with FIG. 3, forming thevent crevice 60 by virtue offolds 62, 64 and 66 which fold lines will be understood to be radial and extending from the aperture to the ring edge as in FIG. 4. In fact, thepleats 35 of FIG. 3 could be readily folded upwardly and flattened against the ring as shown in FIG. 10. However, in FIG. 1 ltheprotective sheet 25 goes over the pleats, although it could tuck into the .additional vent crevice 69. Thebag 12 can either be provided with the downwardly extendingexpansion pleat 72, or' such pleat can be insidecrevice 60 without materially affecting the venting function. In any event, theadhesive coating 22 does not extend intocrevice 60 or 69.
In order to adapt production to a method or machine where it is expensive or impractical to maintain adhesive free areas when the pressure sensitive adhesive is being applied, the entire ring surface can be coated and a protective covering applied to the pleat walls so that when the pleats are folded they cannot adhere wall to wall. Thus ring enlargement and venting would be preserved. This could be effected by using a protective sheet having weakened tear lines at the pleat wall portions so that the sheet can be stripped away leaving portions still adhering to protect the pleats against wall to wall adhesion. Thus, FIG. ll illustratesring 15 with totaladhesive coating 22 covered byprotective sheet 75 which folds into a pleat 35' such as thepleat 35 of FIG. 2 and has weakened slitlines 78 so that the sheet can be peeled away leaving the protective segments betweenlines 78 still covering the pleat walls to prevent adhesion there between. Thus, if each pleat is pinched between the fingers, to grip the protective sheet segments firmly against each other to prevent being pulled away, the main arcuate portions of the protective sheet can be removed.
Referring back to FIGS. 6 and 7, the application to a patients buttocks will be evident, thering 15 is pushed between the buttocks and will flexibly conform to the curvature, the aperture of the ring encompassing the anus and being marginally contiguous therearound, or substantially contiguous. Thetabs 18 adhere diagonally to further ensure retention of the device.
After use, the device is readily removed and discarded; preferably a type of pressure sensitive adhesive is used which minimizes pulling when being removed and, of course, of a non-irritating type suitable for use on human skin. Upon removal,ring 15 can be folded diametrically so that the adhesive surfaces can adhere to each other to contain the contents ofthe bag, thus minimizing messiness.
It will thus be apparent from the above description of the invention that the sphincter muscle of the patient can control expansion and contraction of the ring which will hold the receptacle in proper position toachieve its purpose.Actual tests with prototype models have demonstrated the utility and practicality of the invention and it will be apparent that changes in structure may be made without departing from the spirit thereof. For example,ring 15 need not be circular but can, in fact, assume other shapes.Tabs 18, although desirable, are not essential; and other changes of choice and design may be made.
