Definitions

  • the invention relates to incontinence devices and more particularly to disposable incontinence devices for male, female, and unisex application.
  • incontinence is an embarrassing plague upon a significant percentage of the adult population including both men and women among its victims. Although incontinence is not unknown in children it often becomes an increasingly severe problem during the aging process.
  • Capacity is another problem. Even with a leg bag connected to an accumulation device, as in Moss U.S. patent 3,601,125 the wearer must still periodically transport herself to the restroom whereby the bag can be emptied. This becomes a difficult problem for a non-ambulatory person in a wheelchair at public events, in large crowds of people, as at a ballgame. Whether ambulatory or non-ambulatory, all individuals suffering from incontinence are highly sensitive and secretive about the problem and consequently do not wish to be obliged to wear special garments or devices which cause an unusual appearance when worn under their usual clothing.
  • the present invention provides a compact catheter assembly for transferring fluid waste collecting in a user's bladder, whether of an intermittent or sudden discharge type, to a disposable waste fluid holding unit proximately mountable adjacent the natural bladder discharge orifice.
  • it includes a means for collecting fluid waste from a user and delivering the collected fluid to an outlet having a releasable interconnecting means in sealed liquid communication with a disposable sealed containment means for holding a quantity of fluid waste.
  • the sealed containment means includes an absorbent means carried within the containment means for distributing and absorbing fluid waste delivered through the interconnecting means and preferably includes superabsorbent polymer in combination with fibrous absorbent fluff absorbent material.
  • the sealed containment means is a generally rectangular-shaped pad having a liquid impervious envelope with spaced apart upper and lower surface panels to accommodate the absorbent means and having sufficient volumetric capacity to accept delivery of a full bladder urination.
  • the absorbent material is preferably substantially coextensive with the impervious envelope and preferably con ⁇ tains superabsorbent polymer powder or granules in com ⁇ bination with fibrous fluff with absorbing characteristics.
  • the containment means may be supported by a specially modified panty or a brief.
  • a second embodiment is a compact catheter assembly for extended use in a sitting position to transfer fluid waste collecting in a user's bladder to a disposable waste fluid holding unit positionable on a surface in at least partial support.
  • a means for collecting fluid and a interconnect means it includes a disposable sealed containment means of sufficient volumetric capacity for holding the fluid content of more than one full bladder urination.
  • the absorbent means is carried within the containment means for distributing and absorbing fluid waste delivered through the interconnecting means.
  • the containment means is a pad having a liquid impervious envelope which is adapted to fit on the seat of a chair or a wheelchair and contains a generally centrally located fluid inlet capable of releaseable sealed engagement with the interconnecting means and preferably containing a substantially coextensive layer of fibrous absorbent fluff material coextensive with the impervious envelope in combination with superabsorbent polymer powder or granules which form a gel upon contact with waste fluid.
  • the containment means is large enough to absorb the contents of more than one full bladder urination passing through the inlet. The user is raised above the containment unit at least in partial support by means of a separate donut-shaped cushion which acts as a spacer resting on the envelope of the containment means.
  • the compact catheter assembly for transferring fluid waste collecting within a user's bladder is a wearable waste fluid holding unit shaped like a panty or brief having a means for collecting fluid waste from the urethra.
  • the disposable sealed containment means shaped in the form of a panty-like brief is wearable by a user, provides support for the collecting means, and has sufficient volumetric capacity for holding the fluid content of more than one full bladder urination.
  • the containment means has a liquid impervious envelope having an inner surface for contact with the user's body and a spaced apart outer surface, the surfaces meeting at a peripheral edge, defining two leg holes separated by a crotch area.
  • the fluid inlet is capable of releasable sealed engagement and fluid communication with an interconnecting means, being located in the defined crotch area.
  • an interconnecting means located in the defined crotch area.
  • Between the spaced apart inner and outer panel surfaces is preferably a coex ⁇ tensive layer of fibrous absorbent fluff material in combination with superabsorbent polymer powder or granules substantially coextensive with the impervious envelope and positioned between the inner and outer surfaces thereof.
  • the superabsorbent polymer powder forms a gel upon contact with waste fluid. It is always located adjacent the surface panel of the envelope farthest away from the inlet.
  • the collecting means for any of the above disclosed embodiments are male, female, and unisex.
  • the male collecting means is a thin flexible condom-like sheath tube removably fittable on a male member to form a seal therewith and tapering to form the outlet.
  • the female collecting means is an elongated resiliently deformable body having a cover panel with centralized elongate opening for the female urethra, said body having a resilient non-absorbent insert spaced apart from the cover panel, and being resiliently deformable along with said catheter body, said body tapering to form said outlet space below said cover panel.
  • the unisex collecting means may be described as a Foley catheter. It is an elongated narrow tube with distal openings for fluid which internally reaches the bladder through the urethral opening.
  • a means for venting air is preferably included in one of the interconnecting means releaseably joining the collecting means and the inlet.
  • a means for venting air from the sealed containment means spaced apart from the inlet may be used when the absorbent means includes in com- bination, superabsorbent polymer.
  • the interconnecting means or the inlet itself may carry a one-way flow valve to allow fluid to enter the inlet but restrict the fluid from exiting the inlet. Such valve may be a reed valve, double cylinder valve, or ball valve.

  • the compact catheter assembly unit or catheter unit in operable combination is designated generally by the reference numeral 10. It is equipped with a means for collecting fluid waste from a male shown in position for use in Figure 2.
  • a containment means designated generally by the reference numeral 12 which has a generally rectangular shape. It has an upper surface panel 14 and a lower surface panel 16 spaced apart and opened up to show absorbent material 18. It has a side surface 20 and another oppositely located side surface 22 which together with the upper and lower surfaces taper into end edge 24 on the left side of Figure 1.
  • a similar end edge 26 is seen in Figure 4 opposite end edge 24, which is opened up in Figure 1.
  • Figure 4 also shows that upper and lower surfaces 14, 16 and side surfaces 20, 22 together form a neck portion 28 which is designed to allow some relief in the crotch area between the legs.
  • Containment means 12 is sealed on all surfaces and edges to comprise a liquid impervious envelope.
  • Upper surface 14 may have and fixed thereto a soft fabric layer 30 which serves to improve hand and reduce chaffing. Because the envelope is impervious to liquid the fabric remains dry.
  • fabric 30 is seen adhered to upper surface 14 by a layer of adhesive 32.
  • Upper layer 14 and fabric 30 are seen having an upturned portion 34 to form an opening 36 which is sealed around an inlet 38 which extends below the surface 14 through which waste fluid enters the envelope of the containment means.
  • connector means 40 is carried in sealed fluid communication with inlet 38.
  • the bottom surface of the containment means may have a pair of spaced apart Velcro strips 42 which may cooperate with a corresponding set of Velcro strips on the inside surface of a panty-like brief to removably hold the containment means in correct position for use.
  • connector means 40 has opposed barbed ends one of which is inserted into inlet 38 and the other of which, hidden in Figure 1, is used for releaseably connecting a means for collecting waste fluid, which in Figure 1 is a male collecting means designated generally by the numeral 44.
  • Interconnecting means 40 is a barrel-shaped body supporting the opposed barbed ends with an opening therethrough large enough to pass a full flow urination. It is preferably equipped with an air vent 46 on the side of the barrel shaped body, of the type having a disk which will pass air therethrough but will not allow water droplets to pass through to the outside of interconnect 40.
  • Male collecting means 44 has a thin elastic flexible condom-like sheath tube 48 having an open rolled end portion 50 removably fittable on a male member to form a seal therewith and tapering to form an outlet 52 which removably fits over a barbed end of interconnecting means 40. It may also include an accordian section 54 in the tapered portion leading to outlet 52.
  • the male collecting means is installed on a male member, connected to interconnecting means 40 and contain ⁇ ment means 12. It is supported and held in place by brief 56 on a human wearer. Brief 56 may have Velcro strips corresponding to Velcro strips 42 to help hold it in place.
  • the body itself is of silicone rubber construction with a shape retaining memory. It is soft and easily compressible but returns to its original shape. It is shown distorted to reveal the insert in Figure 5.
  • Each elongate end of the body 60 has a tapered supporting portion 66 terminating in a T-shaped connector 68.
  • the sides of the body taper to form the outlet 70 which is releaseably and sealingly connected in fluid communication with interconnecting means 40.
  • FIG 7 is a cross-section of female collector 58 which shows the insert 64 in supporting contact with the body and curved in the cross direction and in the longitudi- nal direction spaced apart below cover panel 62.
  • Elongate opening 63 in cover panel 62 is indicated along with a narrow slit-like extension 74 of said opening which facili ⁇ tates installing and removing the insert 64.
  • Elongate lip 65 on cover panel 62 forms the opening 63.
  • Insert 64 is conveniently made from scrim rolled into an elongate tube and flattened with stitches 72 to help hold its shape.
  • the unit shown in Figure 5 is shown placed in position in Figure 6 by means of a panty-like brief 76 having a front flap 78 and a rear flap 80 closest to the wearer's skin and hidden by the outer surface of brief 76.
  • T-shaped connectors 68 pass through slits in flaps 78 and 80 to hold the catheter unit 10 equipped with the female collector 58 in proper position for use.
  • Body 60 should be located approximately horizontal with the wearer in a standing position so that waste fluid emanating from the urethra below the edges of the cover panel may pass through the insert and by gravity, flow through the outlet, inter- connecting means and the inlet of containment unit 12 which is supported by the lower portion of the panty-like brief.
  • the containment means preferably has a layer of superabsorbent polymer powder or granules 82 which form a gel upon contact with waste fluid.
  • waste fluid is distributed within the envelope of containment means 12 and fixed instantly as a gel upon contact with the superabsorbent polymer powder. Because the absorbent material is coextensive with the envelope, waste fluid tra- vels to all parts of the containment means and does not accumulate in the lowermost portion of the curved arc in which the containment means must reside to conform with the general shape of the genital area in supporting contact with the panty-like brief.
  • Figure 8 shows a containment means 12 having sealed inlet 38 connected to a portion of interconnect means 40 with arrows showing the direction of flow of waste fluid.
  • the structure is the same as Figure 3 except that underlying fibrous absorbent fluff 18 is a coextensive layer of superabsorbent polymer powder 82 which may also be a series of polymer powder making up layer 82 in combination with sheets of fibrous nonwoven material.
  • the envelope of the containment means must be large enough to accommodate absorbent fill material throughout sufficient to absorb and distribute waste fluid by wicking and absorption. In Figure 8 a more compact envelope than that of Figure 3 is seen.
  • the envelope has a thinner cross-section with shorter side panels than the envelope of Figure 3 because the superabsor ⁇ bent powder will absorb many times its weight of water and instantaneously converts the water into a gel upon contact with the waste fluid.
  • the absorbent material 18 serves to distribute the waste fluid throughout the envelope in contact with the polymer powder which converts it to a gel starting at the centralized opening area and spreading throughout the envelope.
  • superabsorbent polymer When superabsorbent polymer is used it is concentrated under fibrous absorbent material 18 spaced away from the inlet so that the absorbent material 18 can distribute fluid and to avoid having the inlet blocked by gel formation which occurs very rapidly when waste fluid contacts the polymer. Both the absorbent material and the superabsorbent polymer are hydrophillic.
  • Figure 9 shows the containment unit 12 with a unisex collector 84 having an outlet 88 connected to inter ⁇ connecting means 40 and at the opposite end thereof having openings 86 for entrance of bladder contents.
  • the unit works much as before except that the Foley is an elongated hollow tube which is inserted into the urethral opening and reaches into the bladder whereby continuous drainage of fluid from the bladder enters openings 86, travels through the elongated tube to outlet 88 where the fluid enters interconnecting means 40, passes through inlet 38 to enter containment means 12.
  • Containment means 12 has absorbent layers 18, 82 as in Figure 8 and in other respects is like the units previously described. It is likewise held in place by a brief or panty-like brief as indicated by Figure 2 with the catheter inserted as described to collect the waste fluid.
  • Figures 10, 11 and 12 show one-way flow valves mounted at the inlet which pass full flow discharge of waste fluid in one direction but block flow in the opposite direc- tion.
  • Figure 11 shows a reed valve 90 carried by the inlet having an upper stub receiving portion and a lower flattened outlet portion 92 which allows fluid to pass through in the direction of the arrow, the reed valve being of flexible material which closes if subject to outflow pressure caused by fluid moving opposite to the arrow.
  • the rounded upper portion is seen surrounding a portion of interconnect 40 sealed in fluid communication therewith.
  • Figure 10 Another type of one-way valve is disclosed in Figure 10 which itself can serve as an interconnecting means. It is referred to generally as double cylinder valve 94 having a central body portion 96 having opposed barbed stubs 98 and 100. Barbed stub 100 sealingly and removedly engages inlet 38 of containment means 12 and stub 98 removably engages the outlet of any of the male, female or unisex collector means. Fluid flows in a direction of the arrow from the collector means through the combined inter ⁇ connecting means and one-way flow valve to enter the envelope.
  • the lower portion of stub 98 has an O-ring 102 in contact with an outer cylinder 104 holding a reciprocating inner piston 106.
  • the top of inner piston 106 is beveled to engage the O-ring with the piston in the uppermost flow resisting position.
  • Outer cylinder 104 is urged slightly against the O-ring by weak spring 108.
  • Spring 108 is enough to just barely hold the cylinder 104 in place against the O-ring.
  • Outer cylinder 104 reciprocates guided by 90° spaced apart support bars 114 which extend from the wall of central body 96 leaving significant space around cylinder 104.
  • This space is connected to openings 112 and allows full flow through the one-way valve when the piston 106 bottoms in cylinder 104 to move both of them downward against the spring which exposes the openings to the passage of fluid therethrough. Fluid passing in the opposite direction exerts pressure on the bottom of piston 106 which forces it against the O-ring to prevent flow moving in the direction opposite to the arrow.
  • Figure 12 is another one-way flow valve 97 having central body 116 with O-ring 102 and ball 118 urged against the O-ring by another weak spring 120 to prevent flow in one direction opposite the arrow but permit flow in the opposite direction.
  • Ball 118 and spring 120 ride on longitudinal spacer bars located 90° from each other on the inside wall of body 116.
  • Body 116 has opposite barbed stubs 122, 124 for use as before described with a full flow passageway 99 therethrough.
  • FIG. 15 shows as a second embodiment a catheter assembly unit designated generally as 126.
  • Catheter 126 is shown resting supported on chair seat 128. It has a sealed liquid impervious envelope 130 all around which forms an outer perimeter edge 136 which is a generally rectangular or square shape.
  • the envelope has upper surface 132 and lower surface 134. Between the surfaces coextensive with the envelope 130 is absorbent means 18. It may also preferably have superabsorbent polymer layer (82) under a reduced thickness layer of absorbent material 18 as in previous embodiments. As a result the envelope may have a reduced spacing also between the upper and lower surface panels 132, 134.
  • the envelope 130 has sufficient volumetric capacity for holding the fluid content of more than one full bladder urination and may be able to contain two or more depending on how large it is made and how much separation there is between the upper surface 132 and the lower surface 134.
  • Envelope 130 has a generally centrally located fluid inlet 138 in releaseable sealed liquid communication with interconnecting means 40 which may also have air vent 46 to vent air without venting liquid as before described.
  • the unit is shown with a female collector 58 connected in fluid communication without outlet 70 connected to intercon- nect 40.
  • Absorbent material 18 is substantially coexten ⁇ sive with the impervious envelope and has absorbency sufficient to absorb contents of more than one full bladder urination passing through the inlet.
  • the absorbent material could be only absorbent material 18 but also a combination of absorbent tissue or other fibrous absorbent fluff and a layer of gel forming polymer powder 82 which forms a gel upon contact with waste fluid.
  • This one-way flow valve would not be necessary if a sufficient layer of superabsorbent polymer is present to gel the fluid content expected for normal use. Once gelled, the fluid waste is fixed and won't emerge from the envelope even when the envelope is subjected to pressure caused by its supporting the cushion on which the user sits.
  • this unit is different not only in size but in function because it is adapted to fit the seat of a chair having a donut-shaped preferably waterproof cushion 140 removably placed on the upper surface and the unit at least partially supports the user in a sitting posi ⁇ tion on the donut-shaped cushion. Extended use in a sitting position is therefore provided for a patient in a wheelchair or otherwise transported for extended viewing at an outdoor sporting event. Because of the larger size of the unit as compared to the ambulatory units shown in the previous Figures, this disposable unit 126 will meet an incontinent person's needs for an entire afternoon or more. Any of the male, female or unisex collecting means may be used with unit 126 simply by plugging into the barbed stub of interconnect 40. Regardless of which collector is used, the brief or panty-like garment must be provided with an opening commensurate with one of outlets 52, 70 or 88.
  • a third embodiment is seen in Figure 13 and 14.
  • Catheter in the form of a panty-like brief being wearable by a user to provide support for a collecting means and having sufficient volumetric capacity for holding the fluid content of more than one full bladder urination. It is a liquid impervious envelope having an inner surface 144 and a spaced apart outer surface 146 meeting at peripheral edges 148 and 150 defining two leg holes separated by a crotch area 152. The inner surface 154 of crotch 152 has a fluid inlet 156 which is connectable to interconnect means 40 for connecting a male, female or unisex collecting means in fluid communication.
  • Figure 13 shows a female collecting device supported in the wearable catheter unit by the crotch area.
  • the envelope indicated generally as 158 also has waist opening 160 defined by perimeter edge 162.
  • the perimeter edge 162 includes slits (not shown) to form air vents to allow air displaced by fluid entering the envelope to escape to the outside.
  • the envelope 158 is cut away in Figure 13 to show the coextensive layers of absorbent material 18 and superab ⁇ sorbent polymer 82.
  • the absorbent material 18 should be adjacent the inside surface 144 especially at crotch area 152, so that it can perform its distributing function to distribute fluid to the superabsorbent polymer layer.
  • the superabsorbent polymer may also include fibrous material in combination therewith. The absorbent material transports liquid by capillary action and the superabsorbent polymer fixes it as a gel in place upon contact.
  • This unit is ideally suited to utilize absorbent material with superabsorbent polymer, to utilize the large volume between the inner and outer surfaces 144, 146 of envelope 158.
  • the larger volume as compared to the other ambulatory units of Figures 1, 5 and 9 allows sufficient absorbent filler to absorb more than one full bladder urination. As much as two or three such urinations may be held to permit extended wear.
  • the unit may be covered with an outer layer of fabric 164 and an inner layer of fabric 166 which may be joined together at the waist 168. Fabric layers 164, 166 may be of the nonwoven type. Inner fabric layer 166 may have slits to accommodate the T-shaped ends of unit 58 to help hold it.
  • Figure 14 has a liquid impervious envelope covered with a layer of fabric generally designated by the reference numeral 170. It has an outer surface panel 172 and an inner surface panel 174 which has a peripheral edge panel 176 which will form one leg opening and a peripheral edge panel 178 which will form the other leg opening. Peripheral edge 176 is overlapped at side overlap 180 and peripheral edge 178 is overlapped at side overlap 182. The overlap portions are held in place by Velcro tabs 182, 184 on one side and 186, 188 on the other side in a releaseable manner. When overlapped, upper surface panel 190 forms a waist opening 191.
  • the envelope 170 has coextensive absorbent material 18 and superabsorbent polymer layer 82 arranged as in Figure 13 with the superabsorbent polymer contained within the envelope adjacent outer surface panel 172 and the absorbent material in the envelope adjacent inner surface panel 174.
  • waste fluid collected in female collector 58 passing through interconnect 40 and inlet 156 centered in the lowermost portion of the crotch area 192 first contacts the absorbent material upon entry to the envelope, which distributes the fluid to the underlying superabsorbent polymer which fixes it in a gel.
  • the catheter unit 142A of Figure 14 comprises a liquid impervious envelope 170 covered all over with the layer of fabric for comfort. It has the advantage of being adaptable to a range of waist sizes to provide a better fit and is more easily put on and taken off.
  • FIG 16 illustrates the use of a vent in the impervious envelope.
  • the catheter unit is generally designated by the reference numeral 194.
  • Containment means 196 is almost identical to the unit shown in Figure 1. It has an upper surface panel 14, a lower surface panel 16 with side panel 20 and opposite side panel 22 together with necked end portion 28.
  • the upper surface panel 14 may be covered by a fabric 30 bonded thereto.
  • the opposite end (26) is opened up to see the absorbent layer 18 and superabsorbent polymer layer 82. Together they form a liquid impervious envelope.
  • Inlet 198 is a right angle connector having a centralized opening in sealed liquid communication with the interior of the envelope located and centered in the upper surface 14 to which a male collector 44 is attached having outlet 52 releaseably connected to the right angled open end of inlet 198.
  • Inlet 198 has a flange 200 sealed to the under surface of upper panel 14. Any of the male, female or unisex collectors can be releaseably connected to inlet 198.
  • the right angled terminal portion of 198 has a barbed con ⁇ nector portion. The flanged portion can be thought of as an inlet and the right angled extension as an interconnecting means combined in a single structure.
  • Spaced apart from the inlet 198 is a vent 202 located in peripheral edge 24 which ma also be enhanced by stitching 204.
  • This vent may be placed in a similar position spaced apart from the inlet on the catheter units of any of the other Figures when the superabsorbent polymer powder is employed as an underlayer 82 coextensive or partially coextensive with the envelope.
  • Fibrous absorbent fluff 18 lying above the superabsorbent polymer transmits the fluid laterally and downwardly where it instantly forms a gel which fixes it in place.
  • Vent 202 or stitching 204 serve to permit displaced air from the interior of the impervious envelope to be exited outside the unit. Because the waste fluid is fixed in a gel and the vent is spaced apart from the inlet, there is no danger of liquid waste fluid exiting the vent opening.
  • the spaced apart panels of the impervious liquid holding envelope of the containment means are made of a flexible heat sealable plastic and the fabric covering may be woven or non-woven.
  • the female collector is preferably made of a silicone rubber which is soft and flexible but which holds its shape by resilient memory. Naturally, all of the materials in contact with fluid waste are resistant to urine.
  • the interconnect and one-way valves are made of any suitable plastic molding compound. Everything except the containment means is reusable. The containment means is discarded after disconnecting the interconnecting element from the inlet.
  • the one-way valve is not really necessary when the containment envelope contains a layer of the superabsorbent polymer because the liquid which enters the envelope of a given unit is instantly converted to a non- flowable gel which cannot be forced back out of the inlet even under reasonable pressure.
  • the one-way valve element is useful when the containment means has only absorbent fluff material because the fluid is held in the interstices of the fibers and when capacity is readied may be squeezed back out of the envelope if pressure is applied.
  • Superabsorbent polymer by itself is not effective without the layer of absorbent fluff to disperse fluid to it. When the superabsorbent polymer powder is used the amount of absorbent material 18 may be reduced by as much as 25 to 50 percent.
  • the superabsorbent polymer absorbs on a weight basis of about 40 to 1 or more (liquid to absorbing material).
  • An example is that 28 grams of fluff might be used with 2 grams of superabsorbent polymer.
  • the relative amounts of absorbent fiber and polymer may have to be adjusted to achieve optimum liquid holding capacity.
  • the layer of superabsorbent polymer may be only about one fifteenth of the thickness of the absorbent pulp material.
  • the superab ⁇ sorbent polymer is preferably impregnated on thin fibrous tissue or between layers of such tissue to hold it and to help in transmission of the fluid throughout the polymer layer itself.

Abstract

Le système de cathéter compact comprend un élément destiné à recueillir l'urine, s'adapte à l'anatomie des hommes, des femmes et est unisexe, il est interconnecté de manière à être détachable à un ensemble de réservoir jetable possédant une enveloppe imperméable au liquide remplie d'un matériau absorbant et d'un polymère superabsorbant destiné à recevoir et à absorber le liquide provenant de l'urètre. Le liquide provenant de la vessie entre dans l'ensemble de réservoir par un canal d'arrivée. L'ensemble de réservoir peut avoir un trou dans l'élément d'interconnexion et, s'il y a une couche de matériau d'absorption en polymère superabsorbant, l'enveloppe peut être purgée. Les déchets liquides forment rapidement un gel non-liquide avec le polymère superabsorbant. Dans une version, l'élément de réservoir est une serviette maintenue par une culotte. Dans une autre version, l'élément de réservoir est une serviette plus large soutenue par l'assise d'une chaise. Une autre version présente l'enveloppe de réservoir sous forme d'un sous-vêtement. Une valve à sens unique pour le liquide, située sur le canal d'arrivée permet de recevoir le liquide.
