• the drain valve is adapted to receive an end of a flexible tube which can be connected to a larger remote collection container permitting the appliance to be used during the inactive nighttime period.
• the invention relates to drainage appliances and in particular to a drainage bag worn by a patient for receiving and collecting urine discharged through an arti ficial opening surgically formed in the abdominal wall. More particularly, the invention relates to a flexible urine drainage bag suitable for both daytime and nighttime use having means preventing sealing of the abdominal opening and of the appliance discharge drain by the flexible walls of the bag, and which provides a sufficiently flexible appliance for the comfort and convenience of the patient during use.
• the appliance worn during the clay usually consists of a bag constructed of flexible material such as rubber or thin plastic so as to bend and flex with the body movements of the patient, to reduce bulges and projections beneath the patients clothes, and to provide comfort to the patient.
• sealing also may occur at the lower drain opening due to twisting of the bag at this location caused by the tossing and turning of the patient before and during sleep.
• a more rigid bag for nighttime use in an attempt to eliminate such sealing adds to the discomfort of the patient making it more difficult for him to sleep.
• a drainage appliance having a collection bag sufficiently flexible to be worn conveniently and comfortably during the active daytime period, which may be adapted readily for nighttime use by eliminating sealing of the stoma-receiving opening even when the wearer sleeps on his stomach, and which also eliminates sealing of the lower drain opening caused by the twisting and turning of the patient while sleeping.
• an enteros tomy drainage appliance having a flexible bag formed of moisture-proof material such as rubber, plastic or the like, which bag has internal rib means which extends generally throughout the length thereof preventing sealing of the stoma-receiving opening and of a lower drain opening, and in which the internal rib means of the drainage bag are formed with a plurality of transverse slits spaced longitudinally therealong to enable the 'rib means to bend and flex with the body movements of the patient; providing an enterostomy drainage appliance adapted to be worn by a patient during active daytime periods, and which is adaptable further for nighttime use by connection of a drainage tube between the bag drain opening and a remotely located collection container; providing an enterostomy drainage appliance permitting known sealing and attachment means to be used for supporting the bag on the body of the patient, and for providing a moistureproof, nonirritating seal between the bag opening and the patients body, thus enabling usual readily available sealing materials, supporting belts, etc.,

• FIG. 1 l is a fragmentary diagrammatic view showing a flexible tube attached to the bag drain valve and extending to a remote receptacle.
• the improved enterostomy appliance indicated generally at 1, FIG. 1, is shown being worn by a patient 2.
• Appliance 1 has a stoma-receiving opening 3 which is located over the stoma 4 of patient 2 through which the fluid discharged from stoma 4 is received into appliance 1 (FIG. 2).
• Appliance 1 has a flexible bag 5 formed of moistureproof material, such as rubber, plastic or the like, which is not affected or attacked by the fluid discharged from stoma 4.
• Appliance l is intended pn'marintegral with respect to each other or joined at a seam 7a by a heat sealing process, an adhesive or the like. Walls 6 and 7 form a fluid collection chamber 8 therebetween for receiving and storing the discharged fluid when appliance 1 is being worn by patient 2 during active daytime use.
• a usual sealing and attachment device 9 may be used to secure bag 5 to the body of patient 2, and to provide an effective moisture-proof seal around stomareceiving opening 3.
• Device 9 may include a discshaped face plate 10 formed with a central opening 11 and a pair of spaced slots 12.
• a belt or strap 13 extends through slots 12 and encircles the patients waist to secure bag 5 to the patient.
• a shallow cup-shaped disc 15 may be formed as an integral part of rear wall 7 and has stoma-receiving opening 3 formed therein which aligns with face plate opening 11 when mounted on patient 2.
• a disc of vegetable gum material or absorbent padding 16 is placed within rear wall disc 15 and may be coated with an adhesive for sealing bag 5 against the patients body.
• valve assembly 19 is mounted within drain opening 18 and may be secured in neck 17 by an O-ring 14.
• Valve assembly 19 has a generally rigid stem portion 20 having a generally flattened oblong cross-sectional shape, thereby reducing the bulkiness of the stem and enabling stem 20 to lie along the patients leg or body without bulging.
• a usual push-pull closure cap 21 is mounted on the its replacement when bag 5 is replaced.
• Bag 5 preferably is of a sufficiently lowcost enabling it to be replaced periodically.
• Closure cap 21 will be in the closed position of FIGS. 3-5 during the active daytime period when worn by a patient to trap the drained fluid within collection chamber 8.
• Valve 19 also provides an easy and sanitary means for emptying bag 5 while worn by the patient during the daytime upon becoming filled with discharged fluid.
• Rib assembly 25 preferably is formed of a non-absorbent rubber-type material which is unaffected by the discharged fluid. Rib 25 includes a pair of generally straight leg portions 26 and 27 which extend in a generally longitudinal direction throughout the length of bag 5.
• Legs 26 and 27 terminate at the bottom of bag 5 with slightly flared ends 28 and 29, respectively. Ends 28 and 29 flare slightly outwardly and away from each other as shown in FIGS. 3 and 4.
• the upper end portions 30 and 31 of legs 26 and 27 preferably are curved outwardly in generally semicircular configuration and join integrally adjacent the top of bag 5. Curved rib portions 30 and 31 form a generally circular rib config uration 24 about and concentric with bag opening 3 except for the open space 32 between the tops of legs 26 and 27 (FIGS. 3 and 4).
• Portions 26-31 of rib assembly preferably are rectangularly shaped as shown in FIGS. 8, 9 and 10, each having a top surface 33, opposite side surfaces 34 and 35, and a bottom surface 36.
• Bottom surface 36 is attached to the inside surface of front bag wall 6 by an adhesive, bonding, etc., or may be formed as an integral part thereof.
• a plurality of transversely extending slits 37 are formed in top surfaces 33 throughout most of the length of straight leg portions 26 and 27 (FIGS. 4-7). Slits 37 preferably extend throughout nearly the entire depth of legs 26 and 27 except for a small uncut area 38 at the bottom of each slit. Slits 37 are similar to a cut made in the rubber rib assembly by a narrow blade, such as a razor or the like.
• the inner radius of the curved generally circular rib portion 24 formed by inner surface 34, indicated by arrow R (FIG. 4), is slightly larger than the radius of stoma-receiving opening 3 in rear wall 7 and is located oppositely and concentric with opening 3 as shown in FIGS. 3 and 4.
• Upper curved leg portions and 31 preferably are flared outwardly as shown in FIGS. 3 and 4 to form a wider top surface 33 than that of straight leg portions 26 and 27 to provide a broader area which presses against the patients body, adding to the wearers comfort.
• Outer side surfaces of curved rib portions 30 and 31 form a nearly circular configuration 24, approximately three quarters, before merging with the outer side surfaces of leg portions 26 and 27.
• Circular portion 24 is concentric to the semicircular configuration formed by inner surface 34.
• Rib assembly 25 has sufficient thickness, preferably in the range of 1/4 inch to 3/4 inch, to prevent sealing of stoma-receiving opening 3 and fluid chamber 8 by the collapse of walls 6 and 7 as later described.
• Appliance 1 while being worn during the active daytime period by patient 2, will lie in a generally flat vertical condition against the body of the patient (FIG. 2) beneath his outer garments forming the fluid collection chamber 8 therein for receiving any discharged fluid from stoma 4.
• Chamber 8 can retain a considerable amount of discharged fluid before requiring emptying of the contents by drain valve 19 as do heretofore usual enterostomy appliances.
• Slits 37 in leg portions 26 and 27 enable rib assembly 25 and bag 5 to flex easily and conform to the contour of the patients body upon sitting, standing, bending and various other movements of the patient. This flexibility prevents bulges or projections from protruding against the patients garments and adds considerably to the comfort of the patient.
• FIGS. 6 and 7 The flexibility of rib assembly 25 due to slits 37 in leg portions 26 and 27 is illustrated in FIGS. 6 and 7.
• Legs 26 and 27 assure the generally vertical position of FIGS. 5 and 6 while the patient is in standing position.
• the solid rubber forming rib 25 provides sufficient stifiness to resist forces exerted in the direction of arrow A, yet flexes extremely easily in the longitudinal direction due to slits 37 when leg portions 26 and 27 are bent outwardly away from the patients body as during bending and sitting.
• rib assembly 25 prevents the sealing of stoma-receiving opening 3 and collection chamber 8 by the complete collapse of bag walls 6 and 7 during day and nighttime use.
• Rear wall 7 will press against top surfaces 33 of rib assembly 25, and even if tightly pressed and sealed against the portions of front wall 6 located outwardly of rib assembly 25, a sufficiently large channel opening 40 will be maintained between rib legs 26 and 27 (FIGS. 2, 8 and 9).
• curved rib portion 24 prevents sealing of stoma-receiving opening 3 in rear wall 7 as shown in FIG. 2.
• the anti-sealing result produced by rib assembly 25 is important during both day and nighttime use, thereby enabling appliance 1 to be used satisfactorily for both day and nighttime use heretofore not practical with most known flexible bag-type drainage appliances.
• stoma-receiving opening 3 will remain open as shown in FIG. 2, as well as a portion of chamber 8 between and adjacent rib legs 26 and 27 as shown in FIG. 8, to continue to receive drainage liquid.
• appliance 1 An important advantage of appliance 1 is its ability to be worn by a patient while sleeping as well as during active daytime periods. I-Ieretofore the required special nighttime appliance accessories have leaked due to the wide variations in lightweight and heavyweight construction materials and/or the various valve assemblies used in conjunction with the nighttime hook-up accessory. This resulted in patient discomfort due to urine saturation of bedding.
• a usual flexible rubber tube 41 is telescopically mounted on closure cap 21 (FIG. 11) and is frictionally held thereon by engagement with embossed ring 22.
• a separate O-ring or the like also can be used to clamp tube 41 more securely on cap 21 should the patient so desire.
• the other end of tube 41 is connected to a larger fluid receptacle 42 usually mounted on the side of the bed or adjacent thereto. Closure cap 21 is moved to open position after attachment of tube 41.
• Rib assembly 25 provides a continuous drainage channel 40 between legs 26 and 27 from stomareceiving opening 3, through lower drain opening 18, and through tube 41 to the remote drain receptacle 42, even when the patient sleeps on his stomach.
• Flared ends 28 and 29 of leg portions 26 and 27 prevent twisting of the lower bag end as shown in FIG. 9, which heretofore usually resulted in sealing of drain opening 18 of most flexible bag constructions during nighttime use. Even if the valve stem 20 is twisted with Improved enterostomy appliance 1, thus provides an appliance which retains the usual desirable body attachment and sealing means, and the general shape and flexibility of known appliances while achieving the above described desirable results and advantages. Appliance l is equally suitable for both day and nighttime use and enables the patient to lay on his stomach while sleeping-without the opposite wall of the bag pressing against and closing off the stoma opening.
• the rib assembly located within the bag maintains a constant open fluid flow channel between the upper stoma-receiving opening 3 and the lower drain opening 18, yet enables the bag to flex and bend with the body movement of the patient, preventing bulging or undesirable projections beneath the patients garments.
• Appliance l is adapted rapidly and conveniently for nighttime use by attachment of a flexible drainage hose to the drain valve stem at the lower bag end, to connect the appliance to a larger nighttime remotely located fluid collection receptacle.
• the lower flared ends of the rib assembly also prevent twisting of the flexible bag 5 from sealing off the flow of fluid through the drain opening during nighttime use.
• Bag 5 preferably is formed of a rubber or plastic type moisture-proof material which can be produced relatively inexpensively enabling a patient to dispose of the same after several days use, yet which can be cleaned and sanitized for use over a longer period of time should the patient so desire.
• the improved appliance l is very simple in construction, can be mass produced economically and efficiently, is sanitary during use, prevents sealing of the stoma-receiving opening and provides a continuous drainage passage through the bag; and provides a construction which eliminates difficulties encountered with prior devices, achieves the objectives indicated, and solves existing problems in the art.
