Definitions
- the present invention relates to an ostomy appliance comprising a receiving member and a disposable bag liner, a method for producing a compacted inner bag liner, and a method for applying such an ostomy appliance. Furthermore, the present invention relates to a bag being compacted lengthwise while twisting a bottom part in relation to a rim and a method of compacting the same.
- ostomy appliances may be seen in EP 0 768 848, EP 0 703 762, EP 0 768 848, GB 2 306 889, EP 0 821 925 and US 5,423,782.
- an ostomy appliance comprising a base plate, said base plate having a first hole for receiving a stoma, ureter, or catheter and an adhesive wafer having a first surface to be attached to the wearer's abdomen, back, or chest; a receiving member releasabiy attached to the base plate, said member having a second hole for receiving wastes exiting the stoma, ureter or catheter; and a disposable inner bag liner forming a second bag inside the receiving member and being releasabiy attachable to the base plate in a first coupling area by first coupling means, said disposable inner bag liner having a third hole for receiving wastes exiting the stoma, ureter or catheter and the receiving member being releasabiy attachable to the base plate in a second coupling area by second coupling means, the first coupling means being in the form of an adhesive flange projecting from a rim of the third hole and having a
- the receiving member may be a bag allowing the disposable inner bag liner to form a second bag inside the receiving member.
- the second coupling means is in the form of an adhesive flange projecting from the rim of the second hole of the receiving member and having a surface for adhesive sealing against the second surface of the base plate.
- the flange of the receiving member has a skin facing surface and an opposite outer surface.
- the skin facing surface may be adapted to adhere to the base plate or a flange of the same.
- the skin facing surface may be adapted to adhere to the flange of the inner bag liner.
- the outer diameter of the first coupling means may be greater than the inner di- ameter of the second coupling means which allows the use together with coupling means in the form of matching adhesive flanges and also in the form of matching coupling rings.
- the outer diameter of the flange of the inner bag liner may be larger than the inner diameter of the receiving member and thus an overlap is possible. Furthermore, it makes it possible to apply a new inner bag liner to the receiving member prior to attachment of said receiving member to the base plate or a surface thereof.
- the peel strength of the adhesive sealing of the first coupling means could be greater than the peel strength of the second couplings means. This renders it easy selectively to detach the receiving member leaving the inner bag liner attached to a base plate. This may be effected by providing the flange with release properties on the surface facing the receiving member.
- the second coupling means of the receiving member in a third coupling area is releasable attachable to the flange of the disposable inner bag liner, and the peel strength of the adhesive sealing in the first coupling area is greater than the peel strength in the third coupling area.
- the flange of the inner bag liner is provided with a siliconized surface on the side facing the flange of the receiving member in the third coupling area so as to provide smaller adhesive forces between the flange of the receiving member and the flange of the inner bag liner than between the flange of the inner bag liner and the flange of the base plate.
- the second coupling means is in the form of one or more coupling rings, and the outer diameter of the first coupling means is smaller than the inner diameter of the second coupling means.
- the inner bag liner When the inner bag liner stays attached to the base plate, it acts as a drip- catcher and while the user attaches a fresh inner bag liner to the receiving mem- ber which may be reused several times.
- the inner bag liner will thus reduce the risk of escaping odour or soiling of the clothing by dripping output from the stoma.
- the user may easily flush the contents of the receiving member in the WC and is not left with a soiled receiving member but rather with a receiving member, which may be used again or be disposed in a waste bin without obnoxious smells.
- the inner bag liner with a membrane allowing intestinal gas to escape from the inner bag but being impermeable to liquids in order to avoid ballooning.
- the use of an inner bag liner will in itself prolong the active service time of a filter of a receiving member as the contents of the receiving member is separated physically from the filter reducing the risk of blocking.
- the inner bag liner may be used with all types of stomas but the advantages are most pronounced in connection with colostomies and in particular ileo-ostomies where the users typically exchange receiving members two to three times a day.
- the invention relates to an ostomy appliance comprising an adhesive wafer, said adhesive wafer having a first hole for receiving a stoma, ureter, or catheter, said adhesive wafer having a first surface to be attached to the wearer's abdomen, back, or chest and a receiving member attached to the adhesive wafer, said member having a second hole for receiving wastes exiting the stoma, ureter or catheter; and a disposable inner bag liner forming a second bag inside the receiving member and being releasabiy attachable to the adhesive wafer by first coupling means, said disposable inner bag liner having a third hole for receiving wastes exiting the stoma, ureter or catheter, the first coupling means being in the form of an adhesive
- the inner bag liner is compacted lengthwise to form a disc-like structure having an outer diameter less than the inner diameter of the first coupling means.
- the folding of the inner bag liner minimises the risk of "pancaking” and blocking of the bag as the inner bag liner is automatically gradually unfolded or stretched by the output from the stoma first contacting the bottom of the inner bag liner and pressing the same down into the receiving bag.
- the inner bag liner is provided with folding lines for compacting the bag length- wise.
- the folding lines may suitably form spiral lines, which ensures that output from the stoma is disposed directly to the bottom of the inner bag liner causing an unfolding only exposing the sides thereof after filling the lower parts which reduces the risk of adherence to the sides of the inner bag liner.
- the folding lines of the inner bag liner form bellows as well as spiral lines when compacting the bag lengthwise.
- the folding lines of the inner bag liner form telescopic bellows as well as spiral lines when compacting the bag lengthwise.
- the folding lines form spiral lines as the bag is compacted in a lengthwise rotational movement.
- the folding lines are three-dimensional in the twisted state (i.e. the spiral lines), while they are two-dimensional (i.e. defined in one plane) in the unfolded state.
- the inner bag liner is compacted by twist- ing a bottom part in relation to a rim of the bag it is possible to compact the bag in a way which avoids pancaking.
- the twisting is performed while a mandrel is inserted into the bag. When the bag unfolds the bag will 'de- twist'.
- the present invention relates to a method for the preparation of an inner bag liner having folding lines which form spiral lines when the bag is compacted in a lengthwise rotational movement, said method comprising providing an inner bag liner, providing a mandrel placed movably on a base plate and being equipped with openings connected to a vacuum source, locating the inner bag liner sealingly against the base plate with the mandrel projecting into the inner bag liner, evacuating the air from the space between the inner bag liner and the mandrel, and retracting the mandrel in a lengthwise rotational movement such that the bag is compacted and the folding lines define spiral lines.
- the mandrel may be movable with two degrees of freedom; a first degree allow- ing lengthwise movement in and out of a hole in the base plate and a second degree allowing rotation around the length axis of the mandrel.
- the bottom part of the inner bag liner may be retained at the tip of the mandrel by means of a mechanical engagement e.g. by pressing another object against the tip of the mandrel or by means of providing a vacuum at the tip. If vacuum is also provided along the sides of the mandrel it is advantageous to provide a bigger vacuum at the tip of the mandrel in order to retain the bottom part of the bag while the mandrel is rotated.
- the invention in a FOURTH ASPECT, relates to a disposable inner bag liner for receiving effluents or waste products of the body and for use together with an ostomy appliance comprising an adhesive wafer to be attached to the wearer's abdomen, back, or chest, and a receiving member having a hole for receiving wastes exiting the stoma, ureter or catheter; said disposable inner bag liner having a hole for receiving wastes exiting the stoma, ureter or catheter and being capable of forming a bag inside the receiving member and being releasabiy attachable to the adhesive wafer in a first coupling area by first coupling means, the first coupling means being in the form of an adhesive flange projecting from a rim of the hole and having a surface for releasable sealing against a surface of the adhesive wafer, wherein the inner bag liner is provided with folding lines for com- pacting the bag lengthwise, and wherein said folding lines form spiral lines when the bag is compacted
- the disposable inner bag liner of the invention may be used together with exist- ing ostomy devices one-piece ostomy appliances and also together with existing two-piece ostomy appliances, such as appliances comprising a base plate and a receiving member releasabiy attached via matching adhesive flanges or via matching coupling rings.
- a preferred such use is together with one-piece appliances or together with two-piece appliances wherein a base plate and a receiving member are attached via matching adhesive flanges.

- the bag liner is suitably in the form of a co-extruded or laminated sheet having a layer of water-soluble material such as PVA, PVAL or EVAL at the outer surface.
- the inner surface may suitably be made from a mate- rial, which may be processed into a thin layer without pinholes such as PE, EVA, PVC, PP, or a polyester which layer is impermeable for water vapour.
- the outer material may e.g. be in the form of a sheet or a non-woven material.
- An inner bag liner of the invention may be made from a material being permeable for gas and thus permitting intestinal gasses entering the bag to diffuse through the inner bag liner without giving rise to ballooning for management by a conventional gas venting and filtering system placed on the outer bag.
- the inner bag liner is preferably impermeable to water and water vapour in order to avoid leaking of liquid or passing of water vapour which would start a deterioration of the outer layer of the bag liner.
- the disposable inner bag liner of the invention may be provided so that the bottom part of the bag is rotated less than one revolution in relation to the rim part of the inner bag liner.

- the bag is made from front and rear walls welded in a manner known per se along the rim forming a bag. When cutting or punching the walls, an opening for receiving a stoma is suitably also punched in the wall to form the rear wall.
- a protective cover or release liner may for instance be siliconized paper.
- the protective cover is not present during the use of the ostomy appliance of the invention and is therefore not an essential part of the invention.
- the invention in a SIXTH ASPECT, relates to a bag comprising a bottom part and a sidewall extending form the bottom part to a rim of the bag, the bag being compacted lengthwise while twisting the bottom part in relation to the rim such that folding lines defined by at least a part of the sidewall, define spiral lines when the bag is in the compacted state.
- spiral lines (which are defined by the folding lines when the bag is twisted) are three dimensional, whereas folding lines are two- dimensional when the bag is in the unfolded state.

- FIG. 1 and 2 showing an ostomy appliance comprising an base plate, said base plate 1 having a first hole for receiving a stoma 2, ureter, or catheter and an adhesive wafer 3 having a first surface 4 attached to the wearer's abdomen (not shown), back, or chest; a receiving member or bag 5 releasabiy attached to the base plate, said bag having a second hole 6 for receiving wastes exiting the stoma, ureter or catheter; and a disposable inner bag liner 7 forming a second bag inside the receiving member and being releasabiy attached to the base plate, said disposable inner bag liner having a third hole 8 for receiving wastes exiting the stoma, ureter or catheter and being attached releasabiy to the base plate in a first coupling area 9 by first coupling means and the receiving member being attached releasabiy to the base plate by second coupling means in the form of an adhesive flange 10 wherein the first coupling means
- Fig. 2 the inner bag liner and the receiving member are assembled and applied to a base plate placed on the user's skin (not shown) with the stoma projecting into the inner bag liner and the receiving member. As appears, the top of the stoma presses the inner bag liner into the receiving member.
- the flange 10 of the receiving member is adhesively secured and sealed to a flange 18 on the base plate.
- Fig. 3a is shown the embodiment shown in Fig. 2 at the end of the service period during detachment of the receiving member and with the inner bag liner in a stretched state with the its contents 14 received from the stoma.
- the cover 13 is detached and situated in the bottom of the receiving member 5, which is detached from the base plate.
- the inner bag liner is still attached to the base plate and is in the course of being pulled out from the receiving member.
- a flange 18 of the base plate In fig. 3b is shown a flange 18 of the base plate, a flange 10 of the receiving member (second coupling means) and a flange 11 of the inner bag liner (first coupling means).
- the flange 11 is releasabiy attached to the flange 18 of the base plate in a first coupling area 24.
- the flange 10 of the receiving member is releasabiy attached to the flange 18 of the base plate in a second coupling area 22 and to the flange 11 of the inner bag liner in a third coupling area 20.
- the adhesive forces between the flange 11 of the inner bag liner and the flange 18 of the base plate are stronger than the adhesive forces between the flange 10 of the receiving member and the flange 11 of the inner bag liner.
- the flange 11 of the inner bag liner is not removed at the same time. Accordingly it is possible to remove the receiving member and leave the inner bag liner be attached whereby it serves as a drip catcher.
- the adhesive forces between the flange 10 of the receiving member and the flange 11 of the inner bag liner is reduced so as to be smaller than the adhe- sive forces between the flange 11 of the inner bag liner and the flange 18 of the base plate by providing the flange 11 with a siliconized surface on the side facing the flange 10 in the third coupling area 20.
- FIGS 4-6 are shown alternative embodiments of a disposable inner bag liner of the invention in the form of various compacted disposable disc-shaped members for receiving effluents or waste products of the body.
- the compacted disposable inner bag liner members comprise an inner bag liner 7 having a hole 8 for receiving wastes exiting the stoma, ureter or catheter and a first coupling area by first coupling means wherein the first coupling means is in the form of an adhesive flange 11 projecting from the rim of the hole 8 and having a surface 9 for adhesive sealing against a surface of a base plate, said adhesive surface being covered by a release liner R.
- the flange 11 has an adhesive sur- face 12 for releasable sealing against a flange of a receiving member and is covered by a cover 13.
- the inner bag liner 7 and the flange 11 are secured to a ring- shaped element 16 stabilising the rim of the hole 8.
- a further ring-shaped element 17 located between the cover 13 and the flange 11 is shown in Fig.4.
- the inner bag liner comprises a folded part 15 folded in different manners.
- Figs. 4 and 6 is shown an inner bag liner folded forming spiral lines for lengthwise expansion
- Fig. 5 is shown an inner bag liner folded forming a telescopic bellows in combination with spiral lines.
- different embodiments of the ring-shaped element 16 are shown in Figs. 4-6.
- the ring-shaped element may be made from a single or more materials as found suitable for the purpose, typically a foam material showing the desired flexibility and is suitably made from a biodegradable foam material.
- the flange shown in Fig. 4 is relatively narrow and is suitable for use together with two-piece appliances, especially two-piece appliances comprising matching coupling rings for attachment of a receiving member to the base plate, for which purpose, it is suit- able that the flange is not interfering with the coupling area of the coupling rings.
- the embodiments shown in Figs. 5 and 6 have broader flanges and are suitable for use together with two-piece appliances comprising matching adhesive flanges for attachment of a receiving member to the base plate or together with one-piece appliances.
- the disc-shaped member of the invention may in one embodiment comprise the elements a) - f) starting from the side of the cover:
- a relatively large transparent release liner rendering it possible to see through the release liner during assembling the disc-shaped member and a receiving member to ascertain whether the disc-shaped member is located correctly (centrally) before the disc-shaped member is brought into sealing contact with flange of the receiving member.
- the release liner may advantageously have an external diameter corresponding to the external diameter of the flange of the receiving member.
- a flexible and biodegradable or water-soluble adhesive located on the surface of the ring-shaped member (16) and or the flange (11 ) facing a base plate for securing the inner bag liner to the base plate during removal of the receiving member
- a flange (11 ) made from a biodegradable or water-soluble material such as a foam material.
- This flange suitably shows releasing properties at the surface (12) enabling a releasable sealing against the adhesive of the flange (10) of the receiving member.
- the disc-shaped member may be repositioned on the flange (10) if necessary, and is secured to the flange of the receiving member so that the user does not risk losing the disc-shaped member during application of the receiving member to the base plate,
- the risk of damaging the adhesive at the flange of the receiving member is reduced to a very high degree as the surface (12) of the flange (11 ) shows release-properties rather than adhesive properties.
- This flange suitably shows releasing properties at the surface (12) as stated above,
- Step 1 Applying and sealing the disc-shaped member to the flange of the receiving member.
- the diameter of the release liner suitably corresponds to the diame- ter of the coupling flange of the receiving member for facilitating the location using the rims of the flange and of the release liner for centerering the disc-shaped member.
- the flange of the disc-shaped member is transparent and has a diameter greater than the hole of the receiving member, and in this case the transparency of the release liner is utilised for ascertaining that the flange has suffi- cient contact to the coupling flange of the receiving member.
- Step 2 After securing the disc-shaped member to the receiving member, the release liner is removed and the cover is suitably detached from the flange of the disc-shaped member by pressure from e.g. a finger for unfolding the inner bag liner sufficiently to accommodate the stoma in question, and the receiving member is attached to the base plate in the conventional manner according to the type of coupling means.
- Step 3 The inner bag liner is automatically unfolded gradually according to the output from the stoma.
- the first output from the stoma will contact the inner bag liner at the bottom, which again will reduce the risk of "pancaking".
- the inner bag liners of the state of the art are applied in an unfolded state and this will increase the risk of "pancaking", especially when used for colostomies as the output comprises very little water and will adhere to the top of the bag and not fall into the bag.
- Step 4 During substitution the receiving member is detached in the usual manner and the inner bag liner is designed so as to ensure that it is easily withdrawn from inside the receiving member through the centre hole of the coupling flange.
- Step 5 The adhesive at the flange of the disc-shaped member ensures that the inner bag liner stays adhered to the base plate.
- the inner bag liner acts as a drip- catcher and a fresh inner bag liner may be attached to the receiving member as in step 1 at leisure without risking escaping odour or soiling of the clothing by dripping output from the stoma.
- Step 6 When the fresh inner bag liner and the receiving member are assembled, the used inner bag liner is detached and may be flushed in the WC using a single flush.
- the base plate and the stoma may be cleaned in the usual manner and the receiving member provided with a fresh inner bag liner is applied.
- Figs. 7 and 8 show two different embodiments of the disposable inner bag liner 7, in both figures the inner bag liner 7 is unfolded and releasabiy attached via the flange 28 to a disc 30 which in the use situation is removed such that the inner bag liner 7 may be releasabiy attached to a base plate (not shown).
- the disc 30 protects the inner bag liner when it is in the folded or twisted stage and serves as a release liner to which the flange 28 is adhered.
- the disposable inner bag liner 7 in fig. 7 is shaped such that it comprises an upper part 32 which (when the inner bag liner is unfolded) extends upwards in relation to the flange 28 and a lower part 34 which extends downwards in relation to the flange 28, when the inner bag liner is unfolded.
- the mandrel 36 is provided with a plurality of vacuum holes 38 which in the use situation are in connection with a vacuum source (not shown).
- a vacuum source not shown
- On the surface 40 of the mandrel 36 is provided a plurality of vacuum distributing cavities 42 which are used to make sure that the vacuum is distributed to areas of the surface 40 which are not close to the vacuum holes 38. Thereby it is avoided that a vacuum hole is blocked by the inner bag liner whereby the vacuum cannot be distributed to other parts of the surface 40.
- the surface of the mandrel 36 is as smooth as possible so as to ensure that the mandrel 36 does not by accident tear a hole in the inner bag liner 7.
- the tip 44 of the mandrel 36 is round but in some embodiments the tip is substantially flat so as to allow another object to be pressed against the substantially flat surface whereby it is possible to retain the bottom part 46 of the inner bag liner 7.
- the transition zone between the substantially flat tip and the side surface may be rounded.
- the mandrel 36 is inserted into the upper part 34 of the inner bag liner 7.
- the disc 30 is retained in the tool 48 e.g. me- chanically or by means of vacuum.
- the inner bag liner is twisted either by twisting/rotating the mandrel 36 and/or by twisting/rotating the tool 48.
- an interception means 50 is provided, as shown in fig. 11a.
- the interception means 50 could be a brush, a scraper or a mob or an air stream or any other similar ele- ment or means.
- the interception means 50 pushes the upper part 32 towards the mandrel.
- the mandrel 36 is pulled out of the inner bag liner whereby the inner bag liner is pulled down into the compartment 52 of the disc 30, as shown in fig. 11b.
- Means for guiding the twisted inner bag liner into the compartment may be provided (not shown).
- a cover 54 is provided so as to retain the twisted inner bag liner in the compartment 52.
- the mandrel 36 is in a first stage not pulled com letely out of the inner bag liner but rather to a position wherein the tip of the mandrel is aligned the flange 28.
- the means for guiding the twisted inner bag liner pushes the twisted part of the inner bag liner into the compartment 52.
- Another purpose of the cover 54 is to ensure that the adhesive of the outer receiving member does not adhere to the inner bag liner when the inner bag liner is being attached to the outer receiving member.
- Fig. 12 shows the steps of folding the compacted inner bag liner into a compartment and provide it with a cover 54.
- the inner bag liner 7 is twisted by means of an outer rotation tool 56 which is rotated prior to pulling the mandrel 36 out of the inner bag liner 7.
- the tool 56 is also rotated while pulling out the mandrel and in yet other cases the tool 56 is not rotated at all but merely serves as a means making sure that the inner bag liner follows the mandrel closely.
- a tip retaining element 58 may be provided, which is used to retain the bot- tom part 46 of the inner bag liner in relation the mandrel.
