Description

[0001] PORTABLE SYSTEM FOR IRRIGATING THE BOWELS OF A USER

[0002] The present disclosure relates to a portable system for irrigating the bowels of a user.

[0003] Background

[0004] Control of voluntary bowel functions is frequently limited or absent in patients suffering from certain disabilities, such as spinal injuries, multiple sclerosis, or spina bifida. Such lack of control of voluntary bowel functions typically results in faecal incontinence or intractable constipation, as patients have significantly reduced ability to sense the presence of faeces in the colon terminal part and the rectum and to sense the evacuation stimulus.

[0005] It is known to accomplish bowel emptying by irrigation (i.e. flushing) of the bowels via the rectum, by an irrigating fluid, such as tap water or saline, which is provided through an intermittent catheter with a tip which is configured and sized for insertion into the rectum (the rectum being the terminal section of the alimentary canal; from the sigmoid flexure to the anus), where it remains in a fixed position and held by an inflatable element, which may be inflatable by air or by water with a pump. Once the rectum or stoma has been flushed with the irrigating liquid, the inflatable element is removed, and the liquid and faeces can evacuate. Some known irrigation systems suffer from being bulky, complicated, and difficult to handle and to clean properly after use.

[0006] Other types of means for irrigation of bowels such as enema devices are also available. One example includes an enema container configured to be squeezed by the user to expel the irrigation fluid or enema from the container to induce bowel movement, where the container includes an anal probe or applicator to be inserted into the user's rectum. Such known enema devices are often adapted for single-use.

[0007] Some users of the various irrigation systems have limited hand and / or finger dexterity due to medical conditions and therefore may have difficulty in handling the components of irrigation devices, including in the process of cleaning the irrigation liquid container after use. Thus, users of irrigation systems and health care professionals alike would welcome improvements in bowel irrigation devices.

[0008] Summary

[0009] The present disclosure provides a portable system for irrigating the bowels of a user. The system is further defined by the appended claims.

[0022] Detailed Description

[0023] In the following Detailed Description, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. In this regard, directional terminology, such as "top," "bottom," "front," "back," "leading," "trailing," etc., is used with reference to the orientation of the Figure(s) being described. Because components of embodiments can be positioned in a number of different orientations, the directional terminology is used for purposes of illustration and is not necessarily limiting. It is to be understood that other embodiments may be utilized, and structural or logical changes may be made without departing from the scope of the present invention. The following detailed description, therefore, is not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.

[0024] It is to be understood that individual features of the various exemplary embodiments described herein may be combined with each other, unless specifically noted otherwise.

[0025] In this disclosure, solid and liquid waste from the bowels may be referred to as both "output," "waste(s)," and "fluids" interchangeably. A subject using the irrigation system may be referred to as "patient" or "user". However, in some cases, "user" can also relate or refer to a health care professional (HCP), such as a doctor / physician, nurse, or other person.

[0026] In this disclosure, the qualifier "portable" is intended to mean that the system for irrigating the bowels of a user can be carried along with the user without undue effort, i.e., it is neither heavy nor bulky or cumbersome for the user to bring along during activities. The qualifier is further intended to distinguish the system from stationary and / or large bowel irrigation systems, i.e., types of bowel irrigation systems that are mainly used with hospitalized and / or bedridden patients.

[0027] In this disclosure, the words "internal" or "inner" and "external" or "outer" may be used. These qualifiers should generally be perceived with reference to a radial direction, such that a reference to an "external" or "outer" element means that the element is farther away from a centre portion of an element than an element referenced as "internal" or "inner". In addition, "innermost" should be interpreted as the portion of a component forming a centre of the component and / or being adjacent to the centre of the component. In analogy, "outermost" should be interpreted as a portion of a component being the farthest from the centre of the component. In further analogy this is also the case about the use of the words "uppermost" and "lowermost".

[0028] The use of phrases such as (but not limited to) "substantially" and "approximately" as qualifiers of certain features or effects in this disclosure, is intended to simply mean that any deviations are within tolerances that would normally be expected by the skilled person in the relevant field.

[0029] The use of the word "generally" as a qualifier to certain features or effects in this disclosure is intended to mean - for a structural feature: that a majority or major portion of such feature exhibits the characteristic in question, and - for a functional feature or an effect: that a majority of outcomes involving the characteristic provide the effect, but that exceptionally some outcomes may not provide the effect.

[0030] The phrase "adjacent" should be interpreted as being "close to and / or in contact with, or temporarily brought into contact with, but not attached to [something]."

[0031] In a first aspect, the present disclosure relates to a portable system for irrigating the bowels of a user. The portable system includes a container configured to contain a volume of irrigation liquid. The container includes a flexible neck having a first internal surface portion and a first external surface portion. The first internal surface portion of the flexible neck defines a container opening provided around a vertical axis of the portable system. The vertical axis can be considered a central vertical axis of the portable system seen in a longitudinal cross-sectional view of the system components. The container and the elements thereof, such as the flexible neck, has an extent in a direction parallel to the vertical axis (i.e., which extent can generally be considered a "height"). The first internal surface portion of the flexible neck is provided around and may be facing towards the (imaginary) vertical axis of the system to thereby form an opening of the container along the "height" of, and inside of, the flexible neck of the container. The opening of the container allows for passage of irrigation liquid for filling the container before use, and for the passage of irrigation liquid from the container during the process of irrigating the bowels of the user. The irrigation liquid can for example be temperate tap water or a saline physiological solution. In embodiments, the irrigation liquid may exit the portable system via an anal probe attached or coupled to the portable system and in fluid communication with the container.

[0032] The container and elements thereof, particularly the flexible neck, can suitably be made from polymer materials including thermoplastic elastomers (TPE's), silicones, and polypropylene (PP). In embodiments, an entirety of the container including the flexible neck is made from one or more TPE's to make the entire container highly flexible. In embodiments, the pliability of the flexible container allows for the container to be completely invertible, i.e., capable of being turned entirely inside-out, which is a functionality that facilitates easy and thorough cleaning of the container. The easy cleaning helps provide a more sustainable irrigation system than is the case with other known single-use solutions in that at least the container element of the system is suited for re-use after the improved cleaning possibility facilitated by the invertible nature of the container. In embodiments, the container is configured to be invertible to thereby allow for cleaning of the inside walls of the container.

[0033] In alternative embodiments, only portions or elements of the container, such as particularly a portion of the container forming the flexible neck, is / are made from the one or more TPE's to thereby provide the relevant portion(s) or element(s), again particularly the flexible neck, with a higher degree of flexibility than the rest of the container. For example, providing the flexible neck of the container with a high degree of flexibility allows for an advantageous sealing effect to seal the opening of the container. In embodiments, the sealing effect is obtained by press-fitting between the flexible neck and one or more other components of the portable system, particularly a stem component of a lid part of the system (further described below).

[0034] The portable system for irrigating the bowels of a user includes a closure that is suitable for closing (the container of) the system. The closure is configured to be separable from the container, i.e., the container and the closure are separable from each other, and they form two individual elements of the portable system. The separability of the elements from each other further facilitates easy and thorough cleaning of the components of the system. This is particularly advantageous to avoid bacteria or algae growth on internal or inside surfaces or walls of the container, allowing for cleaning and re-use of the container for performing multiple irrigations. The closure of the portable system is adapted to seal and close the container during use of the system. The closure ensures that no spilling of irrigation liquid can take place during use of the system, i.e., when the container contains a volume of irrigation liquid and is handled by the user for irrigation of the bowels.

[0035] The closure includes a collar part and a lid part.

[0036] The collar part of the closure includes a second internal surface portion that is adapted to be attached to the first external surface portion of the flexible neck of the container. The second internal surface portion of the collar part is provided around and faces the first external surface portion of the flexible neck of the container along at least a portion of the "height" of the flexible neck. One or both of the second internal surface portion of the collar part and the first external surface portion of the flexible neck can include complementary engagement means, such as cooperating threading or releasable bayonet-lock type configurations for the attachment of the parts to each other. Alternative complementary engagement means are acceptable, for example including one or more protrusions on the first external surface portion of the flexible neck adapted to combine with one or more corresponding grooves in the second internal surface portion of the collar part. Further alternative ways of engagement can include press-fitting configurations of the collar part and the flexible neck and / or a combination of two or more different kinds of engagement means. In embodiments, the collar part includes one or more engagement flanges for receiving and engaging with corresponding engagement means on the lid part. This provides a possibility for increasing a level of closing friction between the collar part and the lid part of the closure, thereby requiring a greater force to open the closure. In embodiments, the collar part includes a generally level top surface including a generally vertical extending flange. In embodiments, the generally vertical extending flange includes at least one groove provided therein and adapted to receive an engagement means of the lid part. In embodiments, the engagement means on the lid part includes one or more protrusions adapted to engage with the one or more grooves provided in the generally vertical extending flange.

[0037] The lid part of the closure includes a head component and a stem component.

[0038] In embodiments, the head component of the lid part includes a body extending annularly around a central vertical axis of the portable system. In embodiments, the body is formed with a circular or near-to-circular contour when viewed in a top view. In embodiments, at least a portion of the contour of the body is oval or elliptical when viewed in one or more top views. Other shapes or layouts of the contour of the body of the head component are acceptable. In embodiments, the body of the head component has a radial extent configured such that an outer peripheral edge of the body is substantially coinciding with an outer periphery of the collar part of the closure of the system. In embodiments, the body of the head component can include an annular peripheral wall portion configured to surround an internal space defined by the body (i.e., in this case the body of the head component is not a solid body). In embodiments, an inner surface portion of the annular peripheral wall includes engagement means including one or more protrusions adapted to engage with one or more grooves provided in the generally vertical extending flange of the collar part.

[0039] In embodiments, the body of the head component includes a central opening or passage. In embodiments, the portable system includes an anal probe. In embodiments, the anal probe is configured for ejection of the irrigation fluid from the container. In embodiments, the lid part of the closure is adapted to engage with an anal probe configured for ejection of the irrigation liquid from the container. In embodiments, a proximal end portion of the anal probe can be engaged with and be in fluid communication with the central opening or passage of the body of the head component. In embodiments, a proximal end portion of the anal probe can be engaged with and be in fluid communication with the container to facilitate passage of irrigation fluid from the container through the central opening or passage of the body. In embodiments, the irrigation fluid is directed to an outlet at a distal end portion of the anal probe, where the irrigation fluid is ejected. In embodiments, the portable system includes a manipulable valve (automatic or manual) to control access of irrigation liquid between the body of the head component and the anal probe. In embodiments, the body of the head component can advantageously include a shape, form or contour adapted to cooperate with a complementary shape of the anal probe, such as with the proximal end portion of the anal probe. In embodiments, the body of the head component includes a tapering upper surface, tapering from an apex at the central top location of the body to the outer peripheral edge of the body. In embodiments, the anal probe includes a flange or skirt shaped and adapted to cooperatively engage with the tapering upper surface of the body of the head component in fitting relationship. Additionally, and / or alternatively, the body of the head component can include attachment means for releasably attaching the anal probe to the head component, such as, but not limited to, mechanical and / or adhesive attachment means. In embodiments, the anal probe includes a conduit portion extending from the proximal end portion of the anal probe. In embodiments, the central opening or passage of the body of the head component is configured to receive the conduit portion of the anal probe extending from the proximal end portion of the anal probe. In embodiments, the anal probe is configured and designed to be a single-use component of the portable system. Thus, whereas the two or three main components of the portable system may be designed and configured for multiple cleanings and repeated or re-uses, in embodiments the anal probe is a component that is applied for one irrigation event and then discarded. In other embodiments, an anal probe is provided which comprises a base portion and a catheter portion, the catheter portion being separable from the base portion to provide a single-use (exchangeable) catheter or cannula part. In embodiments, the base portion can be provided as an integral part of the head component of the lid part rather than as part of an anal probe.

[0040] In embodiments, the body of the head component is configured to be a generally solid body. It is to be understood that a generally solid body can also include a central opening or passage for fluid communication of irrigation fluid and / or for cooperation with an anal probe. In other embodiments, the body of the head component is configured to be a generally hollow (and thus with an air-containing volume) body. In such embodiments, the hollow body of the head component can include a central pipe or conduit element for guidance and / or cooperative attachment of an anal probe, and / or for being in fluid communication with irrigation fluid in the container.

[0041] In embodiments, the stem component of the lid part of the closure extends a distance from a bottom side (lowermost surface) of the head component. In embodiments, the stem component of the lid part of the closure extends a distance and substantially perpendicular from the bottom side of the head component. In embodiments, the lid part generally takes a form comparable to a mushroom, wherein the stem component forms the stem of the mushroom, and the head component forms the curved or rounded top of the mushroom. In embodiments, suitable materials for the head component and / or the stem component of the lid part include, but are not limited to, polyurethanes (PU's) and / or acrylonitrile butadiene styrene (ABS). In embodiments, the stem component can comprise a central pipe or conduit element for being in fluid communication with irrigation fluid in the container.

[0042] The stem component of the lid part can be understood to have a longitudinal extent in the direction of the vertical axis of the system. The longitudinal extent of the stem component, measured linearly along the vertical axis from the bottom side of the head component, can range approximately between l-50mm. In one embodiment, the stem component is configured to have such a longitudinal extent of about 5mm. In another embodiment, the stem component is configured to have such a longitudinal extent of about 10mm. In another embodiment, the stem component is configured to have such a longitudinal extent of about 15mm. In another embodiment, the stem component is configured to have such a longitudinal extent of about 20mm.

[0043] The stem component of the lid part includes a second external surface portion that is adapted to engage with the first internal surface portion of the flexible neck of the container. Thereby, in one or more embodiments according to the disclosure, the flexible neck of the container may act as part of a sealing and / or generate a major part of a sealing effect between the container and the lid part. In embodiments, an overlap at the point (or area) of contact between the flexible neck and the stem component of the lid part creates a sealing. In embodiments, the sealing engagement between the second external surface portion of the stem component and the first internal surface portion of the flexible neck is configured as a press-fit construction. In embodiments, an external diameter of the stem component is slightly larger than an internal diameter of the flexible neck. In embodiments, the difference in diameters provides a press-fit engagement. In embodiments, a material of the stem component is generally stiffer than a material of the flexible neck of the container. In one, nonlimiting example, the lid part, such as e.g., the stem component comprises one or more of PU, PP or ABS materials and the flexible neck comprises one or more of TPE, PP and / or silicone materials. In embodiments, the stem component is adapted to engage with the flexible neck in a press-fit engagement. In embodiments, the stem component is adapted to slide along at least a portion of a vertical extent ("height") of the flexible neck. In embodiments, the parts are configured in relation to each other such that the force required to engage the parts with each other increases with the extent or length of the sliding distance. In embodiments, a wall thickness of the flexible neck of the container is configured to increase radially inward along the vertical extent to differentiate flexibility of the flexible neck along the central vertical axis of the system. In embodiments, a sliding movement between the engaging stem component and the flexible neck is caused by the lid part being at least partway rotated in a first direction about or around the vertical axis of the system. In embodiments, rotational movement of the container closure in a first direction causes the closure to seal between the external surface of the stem component and the first internal surface portion of the flexible neck and close off the opening of the container, and rotational movement in a second, opposite direction causes the closure to release the seal and open the container. In embodiments, a sliding movement between the engaging stem component and the flexible neck is caused by the lid part being at least partway axially moved along the vertical axis of the system. In embodiments, axial movement of the container closure in a direction downward seen in relation to the vertical axis of the system causes the closure to seal between the external surface of the stem component and the first internal surface portion of the flexible neck and close off the opening of the container, and wherein axial movement in a second, opposite direction causes the closure to release the seal and open the container. In embodiments, the stem component defines an internal volume portion. In embodiments, the internal volume portion of the stem component is configured to transition into an opening, passage, or conduit provided in the head component of the lid part. Irrigation fluid may pass through the volume portion and passage from the container to an anal probe from which it can be ejected.

[0044] In embodiments, the system includes a separable skirt including a third internal surface portion adapted to be attached to the first external surface portion of the flexible neck of the container. In embodiments, the attachment is facilitated by a press- fit engagement between the surface portions. In embodiments, the surfaces are configured to be attached to each other only when the closure of the system is closed, and the system is in use mode. When the closure is not closed, and the system is not in the use mode, the skirt and the flexible neck can be held loosely in position in relation to each other, thus, there may be some space / air between the surfaces until the closure is closed and the system is in use mode. In other embodiments, the third internal surface portion of the separable skirt and the first external surface portion of the flexible neck can include complementary engagement means, such as, but not limited to threads, to facilitate engagement between the surfaces.

[0045] The separable skirt includes a third external surface portion adapted to be attached to the second internal surface portion of the collar part. In embodiments, the third external surface portion of the separable skirt and the second internal surface portion of the collar part include complementary engagement means to facilitate engagement between the surfaces. In embodiments, the second internal surface portion of the collar part of the closure includes a thread. In embodiments, each of the second internal surface portion of the collar part and the third external surface portion of the separable skirt includes threads.

[0046] In configurations of the portable system, it is to be understood that the system includes two or three separate main components, i.e., the container and the closure, and in some configurations also the separable skirt. Providing the portable irrigation system in configurations of two or three separate main components enables a user- friendly system that can be (dis-)assembled manually and is particularly easy to clean after irrigation use. Further, the portable system according to the disclosure decreases manufacturing complexity by eliminating the need for a risky and complex overmolding process step (for otherwise attaching and sealing the closure to the container), and thus advantageously removes or reduces production risks, in that in case of manufacturing complications (e.g., molding process defects or other shortcomings and / or irregularities) not all system components need to be scrapped. In embodiments, some, or all the individual components of the portable system for irrigating the bowels of a user are made from materials suitable for handling tap water with a temperature of between approximately 5° and 60° Celsius, such as between 30° and 45° Celsius. In embodiments, at least the container, the closure, and the separable skirt is made from one or more materials suitable for sustaining temperatures up to 110° Celsius for cleaning purposes.

[0047] In embodiments, the flexible neck of the container comprises a flange extending outward seen in relation to the vertical axis of the system that is adapted to engage with at least the collar part of the closure. In embodiments, the flange of the flexible neck extends radially outward. In embodiments, the flange extends substantially perpendicular to the first external surface of the flexible neck. In other embodiments, the flexible neck of the container comprises a flange extending outward from the first external surface of the flexible neck at an angle less than 90 degrees in relation to the vertical axis of the system. In embodiments, the flexible neck includes two or more radially outward extending flanges. In embodiments, the flange(s) and / or at least one or more portions thereof can have a rounded or bulged shape or contour.

[0048] In embodiments, the second internal surface portion of the collar part of the closure is configured to engage with the first external surface portion of the flexible neck. In embodiments, the first external surface portion of the flexible neck comprises a straight (linear) portion, i.e., a portion without deviations from a linear contour. In embodiments, the flexible neck of the container includes and / or is formed as a cylindrical portion. In embodiments, the second internal surface portion of the collar part is a straight (linear) portion, i.e., a portion without deviations from a linear contour. In embodiments, the second internal surface portion of the collar part is configured to engage with the straight (linear) (or cylindrical) portion of the first external surface portion of the flexible neck. In embodiments, the second internal surface portion of the collar part is configured to engage with the radially outward extending flange of the flexible neck. In embodiments, the second internal surface portion of the collar part includes a first segment with a linear contour and a second segment where the surface includes a first half of complementary engagement means, such as a threaded portion.

[0049] In embodiments, the collar part of the closure comprises a ledge adapted to engage with the outwardly extending flange of the flexible neck of the container. The ledge can for example be adapted to engage with a radially outwardly extending flange of the flexible neck by being able to engage and at least temporarily rest against an upper surface of the radially outwardly extending flange, or at least engage with a portion of the upper surface of the flange.

[0050] In embodiments, the second internal surface portion of the collar part of the closure includes at least one aperture configured to receive and engage with the outwardly extending flange of the flexible neck. In embodiments, the at least one aperture can generally take a U-shape in the second internal surface portion of the collar part. In embodiments, the at least one aperture can be configured as a pocket in the second internal surface portion of the collar part. In embodiments, the at least one radially extending flange of the flexible neck is configured to enter the aperture or pocket in the second internal surface portion of the collar part and to substantially fill up a volume defined by the aperture or pocket. In embodiments, the radially outward extending flange of the flexible neck and the aperture or pocket of the collar part are configured to engage and cooperate to create a strong attachment connection between the components.

[0051] In embodiments, wherein the portable system includes a third main component in the form of the separable skirt, the radially outward extending flange of the flexible neck of the container is adapted to engage with the separable skirt. In embodiments, a downward facing surface of the radially outward extending flange is adapted to engage with the separable skirt. In embodiments, the downward facing surface of the flange is configured to engage with a top portion and / or a top (upwardly facing) surface of the separable skirt. In embodiments, an upward facing surface of the radially outward extending flange of the flexible neck is adapted to engage with the collar part of the closure. In embodiments, the upward facing surface of the radially outward extending flange is adapted to engage with a radially inward projecting top portion of the collar part. In embodiments, the radially inward projecting top portion of the collar part is configured to support at least a portion of a bottom side of the head component of the lid part.

[0052] In embodiments, the lid part of the closure is connected to the collar part of the closure. A connection between the lid part and the collar part of the closure advantageously ensures that the user needs to keep track of fewer individual parts when the system components are separated and / or the portable system not in use, and further ensures that the correct manner of assembling the parts is intuitive to the user.

[0053] In embodiments, the lid part is connected to the collar part by a living hinge. A living hinge (integral hinge) can be a thin flexible hinge (flexure bearing). It can be made from the same material as the pieces it connects, i.e., the lid and the collar part. The minimal friction and very little wear in the living hinge makes it useful in the design of the portable irrigation system. Applying a living hinge for the connection between the lid part and the collar part thus provides a light, non-bulky, yet still sufficiently secure, connection between the parts further being cost efficient in terms of material spend and manufacturing.

[0054] In embodiments of the present disclosure , when the closure is subjected to a rotation action by the user, the second internal surface portion of the collar part engages with either the first external surface portion of the flexible neck (in the configuration including two main components, i.e., the container and the closure) and / or with the third external surface portion of the separable skirt (in the configuration including three main components, i.e., the container, the closure, and the separable skirt). In embodiments, the engaging surfaces include complementary engagement means, such as threads, that engage with each other. In embodiments, force incurred by a rotation action and the engagement between the engaging surfaces drives the closure in downward direction parallel to the vertical axis of the system and causes a closing and / or sealing of the main components to each other. A sealing effect is created by the second external surface portion of the stem component of the lid part being brought into engagement with the first internal surface portion of the flexible neck. In embodiments, the sealing effect of the engagement can be caused by a press-fit engagement between the surfaces. The sealing effect ensures a tight and fluid-proof connection between the container and the closure which prevents leaking of irrigation fluid during use. The portable system of the disclosure advantageously benefits from the pliable character of the material of (at least) the flexible neck of the container to provide a sufficient sealing effect for keeping the system liquid-tight when the container is closed by the closure. This avoids having to incorporate a complex sealing construction and provides a system that can be manufactured with less attention to tolerances, thereby making production both more cost-efficient and faster. In some embodiments a sealing effect can also and / or additionally be created where the collar part is brought into engagement with the flexible neck of the container.

[0055] In embodiments, rotational movement of the container closure in a first direction causes the closure to seal between the external surface of the stem component and the first internal surface portion of the flexible neck and close off the opening of the container, and rotational movement in a second, opposite direction causes the closure to release the seal and open the container.

[0056] In embodiments, axial movement of the container closure in a direction downward seen in relation to the vertical axis of the system causes the closure to seal between the external surface of the stem component and the first internal surface portion of the flexible neck and close off the opening of the container, and axial movement in a second, opposite direction causes the closure to release the seal and open the container.

[0057] In embodiments, the second external surface portion of the stem component of the lid part is adapted to engage with the first internal surface portion of the flexible neck of the container by a press-fit. In embodiments, one or both of the second external surface portion of the stem component of the lid part and the first internal surface portion of the flexible neck of the container including one or more protrusions adapted to further increase friction between the surface portions. In embodiments, the lid part includes engagement means including one or more protrusions adapted to engage with one or more grooves provided in the collar part. This can advantageously combine with the press-fit or protrusions connection between the lid part and the flexible neck of the container to increase friction between them (and thus increase the level of force required to open the closure).

[0058] In embodiments, wherein there are two main components in the form of the container and the closure, the engagement between the first external surface portion of the flexible neck of the container and the second internal surface portion of the collar part of the closure can be facilitated by a press-fit connection. In embodiments, the press-fit connection is provided by applying slightly different dimensions, such as diameters, to the surface portions of the components. In embodiments, the first external surface portion of the flexible neck can include one or more protrusions and / or bulges adapted to create additional grip or friction in the engagement with the second internal surface portion of the collar part. Additionally, and / or alternatively, the second internal surface portion of the collar part can include one or more protrusions and / or bulges.

[0059] In embodiments, wherein there are three main components in the form of the container, the closure, and the separable skirt, the separable skirt is adapted to have a dimensional extent in a direction parallel to the vertical axis of the container in a range of 5-50mm, preferably 10-40mm, more preferably 20-35mm, such as most preferably 25mm. Providing the vertical dimensional extent of the separable skirt in this range ensures that there is sufficient travel distance for the collar part of the closure to create a tight, fluid-proof seal between the container and the closure. This is particularly advantageous in implementations wherein the sealing is created by a rotation action of the closure onto the container. In embodiments, the separable skirt extends along at least a portion of the first external surface portion of the flexible neck of the container. In embodiments, the separable skirt extends parallel, and adjacent to, the first external surface portion of the flexible neck of the container.

[0060] In embodiments, the portable system is delivered in a fully assembled state to the user and may additionally be prefilled with irrigation fluid at delivery, thereby providing a ready-to-use portable system for irrigating the bowels of a user. In embodiments, the portable system can be delivered fully assembled to the user without pre-filled irrigation liquid in the container. In embodiments, the portable system may be subjected to a sterilisation process with or without irrigation liquid in the container before or after packaging of the system.

[0061] An advantageous effect of embodiments of the above-described structure of the portable system is that the flexible neck of the container allows for the main components of the system to be configured for engagement with each other without having to involve a complex and cumbersome over-molding process for manufacturing the system. Due to the pliable nature of (at least) the flexible neck of the container, the closure and / or the separable skirt (if applicable) of the system can be easily attached to (and released again from) the container. Further, per the structure and particularly the pliability of the flexible neck of the container, the system provides a tight, fluid-proof sealing of the components at the point or area of contact between the first internal surface portion of the flexible neck and the second external surface portion of the stem component of the lid part of the closure. Detailed description of the drawings

[0062] Figure 1 is a schematic perspective view of one embodiment of the portable irrigation system 20 according to the disclosure including three main components in the form of a container 22, a closure 34, and a separable skirt 58. Fig. 1 is further a partial view, not showing the bottom or lower (closed) portion of the container 22, i.e., not showing the whole container 22. The system 20 includes a closure 34 and a separable skirt 58. The closure 34 includes a collar part 36 and a lid part 38. The lid part 38 of the closure 34 includes a head component 42 and a stem component 44. The container 22 includes a flexible neck 26. The flexible neck 26 includes a radially outward extending flange 66. The system 20 is configured such that, when the separable skirt 58 is engaged with the container 22, the separable skirt 58 is moved in the downward direction of arrows "A", either by an axial movement or a rotational movement or by a combination of these. The pliability of the flexible neck 26 allows for the radially outwardly extending flange 66 to move through the passage of the separable skirt 58 and to locate a downward facing surface 70 (Fig. 2) on an upward facing surface 72 (Fig. 2) of the separable skirt 58. In embodiments, this engagement ensures that the separable skirt 58 and the container 22 with its flexible neck 26 are attached to each other. In embodiments, engagement, and stability of the combined container 22 and separable skirt 58, may additionally be facilitated by a collar 76 formed (for example provided in the manner illustrated in Fig. 1) as an integral portion of the separable skirt 58. The collar 76 can be adapted to fittingly engage with at least an upper portion of the container 22, as indicated in Fig. 1. Further, when the closure 34 is moved into engagement with the separable skirt 58 (axial / rotational / combined movement) in the downward direction of arrows "B", for example by letting complementary engagement means in the form of threads 64a, 64b engage with each other, the force incurred by the axial and / or rotational movement of the closure 34 relative to the container 22, causes the closure 34 to press down against an upper surface 69 (Fig. 2) of the radially outwardly extending flange 66 and fixes the parts in secure engagement with each other. Moreover, the lid part 38 of the closure 34 can be closed by turning or pivoting the lid part 38 in the direction of arrow "C" around an axis of the connection 74 formed e.g., as a living hinge 74 between the lid part 38 and the collar part 36 of the closure 34. In the embodiment of Fig. 1, the system 20 is adapted such that, when said closing action of the closure 34 is performed, a second external surface portion 56 of the stem component 44 of the lid part 38 (see also Fig. 2) engages with a first internal surface portion 28 of the flexible neck 26 of the container 22 (Fig. 2). At least partly due to the flexible nature and pliability of the material of the flexible neck 26 of the container 22, the engagement between the second external surface portion 56 of the stem component 44 and the first internal surface portion 28 of the flexible neck 26 establishes a secure sealing, which sealing ensures that the closure 34 is fitted to the container 22 in fluid-tight manner. In some embodiments, additional and / or alternative means for creating and / or improving a secure sealing between various components of the system 20 can be applied.

[0063] Figure 2 is a schematic cross-sectional view of one embodiment of the portable system according to the disclosure including three main components in the form of a container 22, a closure 34, and a separable skirt 58. In Fig. 2, the portable system 20 for irrigating the bowels of a user includes a container 22 configured to contain a volume of irrigation liquid 24. The container 22 includes a flexible neck 26. In embodiments illustrated in Fig. 2, the container 22 includes at least the flexible neck portion 26 and a primary fluid holding portion 27. In embodiments, the wall of the container 22 at the primary fluid holding portion 27 includes the same flexible material as the flexible neck 26 of the container. The flexible neck 26 includes a first internal surface portion 28 and a first external surface portion 30. The first internal surface portion 28 of the flexible neck 26 defines a container opening 32 provided around a vertical axis C-C of the portable system 20. The vertical axis can be considered a central vertical axis CL seen in the longitudinal cross-sectional view of the system's components in Fig. 2. The container 22 and the elements thereof, such as the flexible neck 26, has a dimensional extent in a direction parallel to the vertical axis (i.e., which dimensional extent can be considered a "height"). The first internal surface portion 28 of the flexible neck 26 is provided around, and is facing, the vertical axis CL of the system to thereby form the opening 32 of the container 22 along the "height" of, and inside, the flexible neck 26 of the container. The container opening 32 allows for passage of irrigation liquid 24 during filling of the container 22 before use, and for the passage of irrigation liquid 24 from the container 22 during a process of irrigating the bowels of a user. In embodiments, the pliability of the flexible material of the container 22 in its entirety, allows for the container to be turned "inside-out" or inverted to expose the internal surface of the wall of the container 22 for cleaning purposes.

[0064] Further illustrated in the embodiment of the portable system 20 shown in the view of Fig. 2 is a closure 34 suitable for closing (the container 22 of) the system 20. The closure 34 is configured to be separable from the container 22, whereby the closure and the container form two individual elements 22,34 of the portable system 20. One advantage of the separability of the elements from each other is that it facilitates easy and thorough cleaning of the system 20 as well as advantageous manufacturing benefits. The closure 34 is adapted to seal and close the container 22 during use of the system 20 in a manner further described below.

[0065] The closure 34 includes a collar part 36 and a lid part 38. The collar part 36 of the closure 34 includes a second internal surface portion 40 adapted to be attached to either the first external surface portion 30 of the flexible neck 26 (cf. Fig. 6), or, as illustrated in Fig. 2, to a third external surface portion 62 of a separable skirt 58 forming a third individual element in embodiments of the system 20. The second internal surface portion 40 of the collar part 36 is provided around and faces the first external surface portion 30 of the flexible neck 26 of the container 22, or alternatively faces the third external surface portion 62 of the separable skirt 58 (Fig. 2) along at least a portion of the "height" of the flexible neck 26, or skirt 58, respectively.

[0066] The lid part 38 of the closure 34 includes a head component 42 and a stem component 44. In the embodiment illustrated in Fig. 2, the head component 42 of the lid part 38 includes a body 46 extending annularly around the central vertical axis C-C of the portable system 20. In the cross-sectional view of Fig. 2, at least a portion of a contour 48 of the body 46 can be seen to be curved. The body 46 has a radial extent configured such that an outer peripheral edge 50 of the body 46 coincides with an outer periphery 52 of the collar part 36 of the closure 32. In Fig. 2, the body 46 of the head component 42 is generally hollow. The body 46 of the head component 42 can include (not shown in Fig. 2) a central pipe or conduit portion for guidance, cooperation, and attachment with an anal probe and for being in fluid communication with irrigation fluid in the container 22.

[0067] In the embodiment of Fig. 2, the stem component 44 of the lid part 38 of the closure 32 can be seen to extend a vertical distance and substantially perpendicular to a bottom side 54 of the head component 42. In the embodiment of Fig. 2, the lid part 38 may be understood to generally take a form comparable to a mushroom, wherein the stem component 44 is the stem of the mushroom, and the head component 42 with curved contour 48 forms the rounded top (or cap) of the mushroom.

[0068] The stem component 44 can be seen to have a longitudinal (vertical) extent in the direction of the central vertical axis C-C of the system 20. The longitudinal extent of the stem component 44, measured linearly along the central vertical axis CL from the bottom side 54 of the head component 42 can range approximately between 1- 50mm. The stem component 44 includes a second external surface portion 56 adapted to engage with the first internal surface portion 28 of the flexible neck 26 of the container 22. In the embodiment of Fig. 2, the engagement between the second external surface portion 56 of the stem component 44 and the first internal surface portion 28 of the flexible neck 26 is configured as a press-fit engagement.

[0069] In the embodiment of Fig. 2, the system 20 is further illustrated to include a separable skirt 58 including a third internal surface portion 60 adapted to be attached to the first external surface portion 28 of the flexible neck 26. The separable skirt forms a third individual and separable element of the system 20. In embodiments, attachment between the separable skirt 58 and the flexible neck 26 is established by a press-fit engagement between the surface portions 28, 60. Fig. 2 further illustrates embodiments, wherein the separable skirt 58 includes a third external surface portion 62 adapted to be attached to the second internal surface portion 40 of the collar part 36. The third external surface portion 62 of the separable skirt 58 and the second internal surface portion 40 of the collar part 36 can include complementary engagement threads 64a, 64b, to facilitate engagement between the surface portions 40, 62. In embodiments, the engagement threads 64a of the second internal surface portion 40 extends only partway along the second internal surface portion 40.

[0070] In the configurations of the portable system 20 as illustrated in Fig. 2, it is understood that the system includes three main components which are separable from each other, i.e., the container 22, the closure 34, and the separable skirt 58. Configuring the portable irrigation system 20 with two or more separable main components 22, 34, 58 provides, among other advantages, a portable system 20 that is easy for the user to clean after use.

[0071] In the embodiment of Fig. 2, the flexible neck 26 of the container 22 additionally includes a flange 66 extending radially outward seen in relation to the central vertical axis CL of the system 20. The flange 66 is configured to engage with the collar part 36 of the closure 34. In the embodiment of Fig. 2, the flange 66 extends substantially perpendicular to the external surface 30 of the flexible neck 26.

[0072] In Fig. 2, the second internal surface portion 40 of the collar part 26 is shown to (at least partially) engage with the radially outward extending flange 6 of the flexible neck 26. In embodiments as illustrated by Fig. 2, the second internal surface portion 40 of the collar part 26 includes a first segment with a linear contour and a second segment where the surface includes a first half of complementary engagement means, such as thread 64a configured to engage with thread 64b of the separable skirt 58.

[0073] In embodiments as illustrated in Fig. 2, the collar part 36 of the closure 34 comprises a ledge 65 adapted to engage with the radially outwardly extending flange 66 of the flexible neck 26. The ledge 65 is shown to engage with a portion of an upper (upwardly facing) surface 69 of the flange 66.

[0074] In embodiments as illustrated in Fig. 2, wherein the portable system 20 includes a separable skirt 58, the radially outward extending flange 66 of the flexible neck 26 is configured to engage with the separable skirt 58. In Fig. 2, a downward facing surface 70 of the radially outward extending flange 66 is adapted to engage with the separable skirt 58. In embodiments, the downward facing surface 70 of the flange 66 is configured to engage with a top portion or top surface (upwardly facing) 72 of the separable skirt 58. In embodiments, the upward facing surface 69 of the radially outward extending flange 66 of the flexible neck 26 is adapted to engage with the collar part 36 of the closure 34. In embodiments, the upper or upwardly facing surface 69 of the radially outward extending flange 66 is adapted to engage with the ledge 65 of the collar part 36. In the embodiment of Fig. 2, the ledge 69 is formed by a surface of a radially inward projecting top portion 73 of the collar part 36. In Fig. 2, the radially inward projecting top portion 73 of the collar part 36 supports at least a portion of the bottom side or surface 54 of the head component 42 of the lid part 38.

[0075] In Fig. 2, the lid part 38 of the container closure 34 is connected to the collar part 36 of the closure 34 by a connection 74. The connection 74 between the lid part 38 and the collar part 36 ensures that the collar part 36 and the lid part 38 of the closure 34 are kept together when the system's main components 22, 34, 58 are separate from each other during non-use of the system. Various types of connection constructions may be applied. In one solution as illustrated in Fig. 2, the lid part 38 is connected to the collar part 36 by a living hinge 74. The lid part 38 of the closure 34 can be closed by turning or pivoting the lid part 38 around an axis of the living hinge 74.

[0076] By turning or pivoting the closure 34, the second external surface portion 56 of the stem component 44 engages with a first internal surface portion 28 of the flexible neck 26 and establishes a secure fluid-tight sealing of the closure 34 to the container 22.

[0077] Figure 3 is a partial, cross-sectional view of one embodiment of the portable system 20. In the view of Fig. 3, the body 46 of the head component 42 includes a central opening or passage 78 with which a proximal end portion 80 of an anal probe 82 (see Fig. 4) can be engaged and be in fluid communication with the container 22 to facilitate passage of irrigation fluid 24 from the container 22 through the central opening or passage 78. In embodiments as illustrated in Fig. 3, the body 46 is configured to be a generally solid body 46 except for the passage 78 extending through the body. The body 46 of the head component 42 includes a curved upper surface 86 tapering from an (schematically illustrated) apex 88 located where the vertical central axis CL intersects the body 46 to an outer peripheral portion 90 of the body 46.

[0078] Figure 4 is a schematic, perspective view of one embodiment of the portable system 20 including the three main components container 22, closure 34, and separable skirt 58. In embodiments as illustrated in Fig. 4, the system 20 further includes an anal probe 82. The anal probe 82 includes a proximal end portion 80 adapted to engage with the central opening or passage 78 in the body 46 of the head component 42 (Fig. 3) of the closure 34. One embodiment of an anal probe 82 includes at least one outlet opening 83 at a distal end portion 84 of the anal probe 82.

[0079] In embodiments, the curved upper surface 86 of the body 46 of the head component 42 (Fig. 3) is advantageously configured to cooperate with a complementary shape of the anal probe 82, such as with the proximal end portion 80 and a surrounding lower base portion 81 of the anal probe 82 (Fig. 4). Additionally, the body 46 of the head component 42 can include attachment means (not shown) for attaching the anal probe 82 to the head component 42, such as to the lower base portion 81 of the anal probe 82. In embodiments, the central opening or passage of the body 46 of the head component 42 is configured to receive the proximal end portion 80 in the form of a conduit portion extending axially beyond the lower base portion 81 of the anal probe 82.

[0080] Fig. 5 is a partial perspective view of one embodiment of the portable system 20, wherein the system includes two individual main components in the form of container 22 and closure 34. In embodiments as illustrated in the view of Fig. 4, the collar part 36 of the closure 34 includes a second internal surface portion 40 adapted to be attached to the first external surface portion 30 of the flexible neck 26. Thus, in the embodiments illustrated by the view of Fig. 5, the closure 34 is attached directly to the flexible neck 26, different from the Figs. 1-4 illustrations, wherein the closure 34 is attached to the flexible neck 26 via a third main component in the separable skirt 58. In the embodiment illustrated in Fig. 5, the collar part 36 of the closure 34 includes a generally level top surface 96 including a generally vertical extending flange 98. The generally vertical extending flange 98 includes a groove 100 provided therein adapted to receive an engagement means in the shape of a protrusion 102 provided on an inner surface portion 104 of an annular peripheral wall 106 that surrounds an internal space 108 defined by a body of the head component of the lid part 38. Fig. 5 further shows a connection between the lid part 38 and the collar part 36 of the closure 34 in the form of a living hinge 74.

[0081] Fig. 6 is a partial, cross-sectional view of one embodiment of the portable system 20, wherein the system includes two individual main components in the form of container 22 and closure 34. In embodiments as illustrated in Fig. 6, the first external surface portion 30 of the flexible neck 26 includes one or more (two depicted in Fig. 6) protrusions 92 adapted to engage with the second internal surface portion 40 of the collar part 36 of the closure 34. In embodiments, the second internal surface portion 40 of the collar part 36 includes at least one aperture 94 configured to receive and engage with the one or more protrusions 92 of the first external surface portion 30 of the flexible neck 26. The at least one aperture 94 can generally take the form of a pocket in the second internal surface portion 40 of the collar part 36. In embodiments, a radially outward extending flange 66 of the flexible neck 26 and the aperture 94 of the collar part 36 are configured to cooperate to create a strong attachment connection between the container 22 and the closure 34 components of the system 20. Alternative means or constructions for engagement between the components can be acceptable, for example including one or more apertures in the first external surface portion 30 of the flexible neck 26 adapted to combine with one or more corresponding protrusions on the second internal surface portion 40 of the collar part 36.

[0082] Figures 7 and 8 are schematic cross-sectional views of other embodiments of the portable system 20 with alternative configurations of the main components, and particularly illustrating alternative configurations of the flexible neck 26 of the container 22 and of the collar part 36 of the closure 34 and their manner of engagement with each other, in accordance with the present disclosure.

[0083] Figures 9A-9C are schematic cross-sectional views intended to illustrate one of the advantageous effects of the portable system 20 according to the disclosure. According to embodiments of the disclosure, the pliability and flexibility of the container 22 allows for the container to be entirely (completely) invertible, i.e., capable of being turned entirely inside-out, which functionality facilitates easy and thorough cleaning of the container. Moreover, the separability of the individual main components of the system 20 further ensures and allows easy cleaning of the system components.

[0084] Although particular features have been shown and described, it will be understood that they are not intended to limit the claimed invention, and it will be made obvious to those skilled in the art that various changes and modifications may be made without departing from the scope of the claimed invention. The specification and drawings are, accordingly, to be regarded in an illustrative rather than restrictive sense.
