Patent Description:
An ostomy pouch typically includes opposing side walls defining an internal collection area. One of the side walls is provided with an opening to receive a stoma, and means to secure the pouch to the user, such as an adhesive barrier, so that bodily waste discharged through the stoma is received within the collection area without leakage from the stoma/barrier/pouch environment.

A drainable ostomy pouch may further include a drainage port at a lower end of the pouch. In a known drainable ostomy pouch, the drainage port is formed as a narrowed neck portion having an opening extending therethrough. The drainage port is operable between a closed condition and an open condition. In the closed condition, the drainage port is configured to substantially seal the lower end of the drainable ostomy pouch so that bodily waste may be securely collected and stored in the collection area. In the open condition, the bodily waste may flow from the collection area through the opening to be drained from the ostomy pouch.

Alternatively, the drainable ostomy pouch may be part of an ostomy drainage system, such as a night drainage system or other high volume drainage system. In an ostomy drainage system, the discharge port is coupled to a hose, and the hose is connected to a relatively larger volume drainage bag. Thus, the contents may flow from the ostomy pouch, through the opening of the discharge port and the hose, to be received in the drainage bag. Accordingly, the ostomy drainage system has increased storage capacity relative to the ostomy pouch alone and may require less frequent emptying.

In a known drainable ostomy pouch, the drainage port may be formed continuously with the side walls. To close the drainage port, the neck portion may be folded or rolled and held in place with a fastener. In the closed condition, the opening in the discharge port is substantially closed to seal against egress of the pouch contents (i.e., the bodily waste) through the discharge port. The discharge port may be moved to the open condition by releasing the fastener and unrolling or unfolding the neck portion. However, an ostomy pouch with this type of discharge port is difficult to connect to a hose in a drainage system because the discharge port lacks rigidity. In addition, folding or rolling the discharge port, and subsequent fastening, as described above, may be time consuming and difficult for some users with limited dexterity. Further, it may be difficult to determine when the discharge port is adequately closed to seal against unwanted egress of pouch contents.

In another drainable ostomy pouch, the discharge port may include an outlet body. The outlet body is formed of a thicker, more rigid material than the side walls of the ostomy pouch and is connected to the side walls, for example, by heat sealing. The opening in the discharge port extends into the outlet body. The opening may extend through an end of the outlet body to allow for egress of the pouch contents through the outlet body in the open condition. In a closed condition, a cap or plug may be friction fit over or fitted into the opening in the outlet body. When the drainable ostomy pouch is used in an ostomy drainage system, an adapter may be friction fit to the outlet body and a hose may be connected to the adapter. Accordingly, the pouch contents may drain through the adapter and hose.

Alternatively, the opening may terminate at a normally closed slit at the end of the outlet body. The slit may form a squeeze valve, whereby in response to application of opposing, inwardly directed forces, the slit opens to allow for egress of the pouch contents. In the closed condition, a cap may be friction fit over the end of the outlet body to further seal against unwanted egress. When the drainable ostomy pouch having the outlet body described above is used in an ostomy drainage system, the discharge port may be moved to the open condition by squeezing the outlet body, and an adapter connected to a hose inserted into the opening, through the open slit, to be friction fit to the outlet body.

However, in the discharge ports above, it may be difficult for a user to confirm an adequate coupling between the outlet body and the cap, plug or adapter. In addition, the friction fit coupling between the outlet body and the cap, plug or adapter described above may be overcome by application of a force in a direction which moves the cap, plug or adapter away from the outlet body, or vice versa. It has been found that in some instances, inadvertent or accidental contact with a component of the ostomy drainage system may be sufficient to overcome the friction fit coupling, thereby causing the outlet body and the cap, plug or adapter to inadvertently separate from one another, leading to unintended drainage or emptying of the ostomy pouch.

Further, a wearer may find the outlet body to be uncomfortable. For example, because of the relatively more rigid construction of the outlet body, a corner or edge of the outlet pressed against the wearer's skin may cause discomfort. Further still, a relatively soft or flexible discharge port of the type that may be rolled or folded, or a discharge port including a valve structure, such as a squeeze valve, may be susceptible to clogging.

<CIT> is considered to represent the closest prior art and J <NUM>. discloses a valve for an ostomy pouch that is sealable to an associated container having an interior fluid storage region is adapted to permit and stop flow of fluid from the fluid storage region. The valve includes a body sealable to the container and a stem mounted to the body having a portion in flow communication with the storage region. The stem is movable relative to the body between an open position to permit flow from the storage region through the valve, and a closed position to stop flow through the valve. The stem has a grasping region spaced from the body that is adapted rotate the stem to move the valve between the open and closed positions. The grasping region has first and second sides. One of the sides has a tactile indicator to provide indication of the position of the valve, the other side is devoid of the tactile indicator.

<CIT> discloses a stoma drainage appliance having a fluid collecting pouch constructed of sheets of flexible material with two internal sheets sealed together at spaced intervals to provide a valve across the center of the pouch precluding upward flow of fluid between the two internal sheets. There is at least one unsealed space between the seals located so as to provide a direct, straight path from an inlet opening of the upper section of the pouch to the lower section of the pouch. The stoma drainage appliance further includes an outlet spout connected at the lower section of the pouch. The spout has a tapered opening with an inlet neck section of oval cross-section and an outlet end section of circular cross-section. The spout is made of flexible material for clamping along the neck section to close the spout and includes a cap for attachment to the end section thereof. A tubular coupling member is provided for connecting to the spout and it has an opening of tapered construction to accommodate external conduits of varying size.

Accordingly, it is desirable to provide an ostomy collection and drainage system in which feedback may be provided to the user to confirm coupling between an outlet body and a closure or adapter.

The scope of the invention, however, is solely defined by the appended claims.

Referring to <FIG>, an ostomy collection and drainage system <NUM> includes an ostomy pouch <NUM> having an outer wall <NUM> defining an internal volume to form an internal collection area (not shown). The outer wall <NUM> may have an inlet opening <NUM> formed therein. The inlet opening <NUM> is disposed in fluid communication with the internal collection area and is configured to receive a stoma so that a discharge from the stoma may be received in the internal collection area and stored in the internal collection area as contents of the ostomy pouch <NUM>. The inlet opening <NUM> may be positioned at an upper portion of the ostomy pouch <NUM>.

An outlet body <NUM> is secured to the outer wall <NUM>. In one embodiment, the outlet body <NUM> is positioned at a lower portion of the ostomy pouch <NUM> and is configured to selectively allow drainage of the contents from the internal collection area, to seal against drainage of the contents from the internal collection area, and to connect to a high volume drainage system, such as a night drainage system, described further below. In one embodiment, the outlet body <NUM> may be secured to the outer wall <NUM> for example, by heat sealing, with an adhesive, or by being formed together with the outer wall <NUM>, for example in a molding process, such as a two-shot molding process. Preferably, the outlet body <NUM> is secured to the outer wall <NUM> in such a way that a seal is formed between the outlet body <NUM> and the outer wall <NUM>, to prevent or limit undesired leakage of the contents between the outer wall <NUM> and the outlet body <NUM>.

The ostomy collection and drainage system <NUM> further includes a closure <NUM> and an adapter <NUM>, each configured for removable and interchangeable coupling to the outlet body <NUM>. In one embodiment, the closure <NUM> and the adapter <NUM> are interchangeably coupled to the outlet body <NUM> such that in a first condition the adapter <NUM> is coupled to the outlet body <NUM> and in a second condition the closure <NUM> is coupled to the outlet body <NUM>. In one embodiment, the closure <NUM> and the adapter <NUM> may be interchangeably coupled to the outlet body <NUM> by way of a latch engaging a catch in friction or interference fit, including a snap fit, and optionally, a mechanical interlock to restrict movement of the closure <NUM> or adapter <NUM> relative to the outlet body <NUM>, for example, in an axial or substantially axial direction D1. A tube <NUM> may be connected to the adapter <NUM> to fluidically connect the ostomy pouch <NUM> to, for example, a night drainage bag (not shown).

<FIG> is a bottom perspective view of an outlet body <NUM> configured for connection to an ostomy pouch <NUM> in an ostomy collection and drainage system, according to an embodiment described herein. <FIG> is a front view of the outlet body <NUM> of <FIG>. Referring to <FIG>, the outlet body <NUM> generally includes an outlet opening <NUM> through which contents of the ostomy pouch <NUM> may be drained. The outlet opening <NUM>, in one embodiment, extends along a first axis A1. In one embodiment, the outlet opening <NUM> may have a width or diameter W of about <NUM> to about <NUM>. For example, in one embodiment, the outlet opening <NUM> may have a width or diameter W of about <NUM> to about <NUM>.

<FIG> is another side view of the outlet body <NUM> of <FIG>. With reference to <FIG>, the outlet body <NUM> includes one of a latch and a catch, which are configured for releasable engagement with one another as described further below. In one embodiment, the catch <NUM> is formed on the outlet body <NUM>. The catch <NUM> may be formed as a projection which extends radially outward and in a peripheral direction along at least a portion of a periphery on the outlet body <NUM>. In one embodiment, the outlet body <NUM> includes two catches <NUM> similarly formed and spaced apart from one another by a gap <NUM> in the peripheral direction.

In one embodiment, the catch <NUM> includes a first surface <NUM> which may be an upper surface of the catch <NUM>. It is understood however, that the directional term "upper" does not limit the outlet body <NUM> and the catch <NUM> to a particular orientation, but rather, is used only as example consistent with the orientation of the outlet body <NUM> and catch <NUM> as shown in the drawings. In one embodiment, the catch <NUM> includes at least one peak <NUM> formed as a section of increased height extending upwardly on the first surface <NUM>. In one embodiment, the catch <NUM> includes two peaks <NUM> spaced apart in the peripheral direction on the outlet body <NUM>.

As more clearly shown in <FIG>, a closure <NUM> is configured for removable coupling to the outlet body <NUM>. For example, the closure <NUM> may be removably coupled to the outlet body <NUM> by way of a frictional engagement with the outlet body <NUM> in the outlet opening <NUM>. In one embodiment, the closure <NUM> includes a plug <NUM> having an outer surface configured to frictionally engage an inner surface <NUM> around the outlet opening <NUM>. Preferably, the frictional engagement between the plug <NUM> and the inner surface <NUM> is a sealed engagement to substantially prevent or limit unintended egress of the contents through the outlet opening <NUM>. In one embodiment, the plug <NUM> may include one or more ribs <NUM>. The one or more ribs <NUM> may extend either partially or entirely about an outer periphery on the plug <NUM>.

Referring still to <FIG>, the closure <NUM> may also include a cap <NUM> configured, in one embodiment, to engage an axial end <NUM> of the outlet body <NUM> when the plug <NUM> is engaged in the outlet opening <NUM>, i.e., in the second condition. The cap <NUM> may be formed having a width greater than a width of the plug <NUM>. In one embodiment, the cap <NUM> and the plug <NUM> are formed as a single, continuous unit. Further still, in one embodiment, the closure <NUM> may be connected to the outlet body <NUM> with a flexible member <NUM>, such as a strap or living hinge.

Accordingly, in the embodiments shown in <FIG>, the closure <NUM> may be coupled to the outlet body <NUM> by positioning the plug <NUM> in the outlet opening <NUM> in frictional engagement with the inner surface <NUM>. With the closure <NUM> so positioned, the ostomy pouch <NUM> is configured to collect and store discharge from a stoma. With the closure <NUM> removed from the outlet opening <NUM>, the contents (i.e., the stoma discharge) may be drained from the ostomy pouch <NUM> through the outlet opening <NUM>.

<FIG> is a front perspective view of an adapter <NUM> according to an embodiment described herein. The adapter <NUM> includes an adapter opening <NUM> extending therethrough. In one embodiment, the adapter opening <NUM> extends on a second axis A2.

The adapter <NUM> includes the other of the latch and the catch that is formed on the outlet body <NUM>. For example, in one embodiment, the adapter <NUM> includes a latch <NUM> configured to releasably engage the catch <NUM>. In one embodiment, the adapter <NUM> may include two or more latches <NUM>. In one embodiment, the number of latches <NUM> is equal to the number of catches <NUM>, but the present disclosure is not limited to such an embodiment. In addition, it is understood that in another embodiment the outlet body <NUM> may be formed with the latch <NUM> and the adapter <NUM> may be formed with the catch <NUM>.

The latch <NUM> and the catch <NUM> are configured for releasable engagement with one another by way of a friction or interference fit, including a snap fit, to couple the adapter <NUM> and outlet body <NUM> together. In addition, the latch <NUM> and the catch <NUM> may form a mechanical interlock to resist movement in, or substantially in, the axial direction D1 of the adapter <NUM> relative to the outlet body <NUM>. In one embodiment, the latch <NUM> and the catch <NUM> may be brought into engagement by way of rotational movement relative to one another. In one embodiment, the relative rotational movement brings the latch <NUM> and catch <NUM> into a position where the mechanical interlock is formed, and the adapter <NUM> is coupled to the outlet body <NUM>.

In one embodiment, the latch <NUM> includes a first portion <NUM> extending generally in the axial direction D1. The latch <NUM> may also include a second portion <NUM>, formed as an inward projection, such as a hook, at a free end of the first portion <NUM>.

Referring still to <FIG>, the adapter <NUM> includes a first collar <NUM> and a second collar <NUM>. In one embodiment, the first collar <NUM> is configured to frictionally engage the outlet body <NUM>, for example, within the outlet opening <NUM>. Preferably, the frictional engagement of the first collar <NUM> within the outlet opening <NUM> is a sealed engagement. The first collar <NUM> may include a peripherally extending bead <NUM> configured for engagement with the inner surface <NUM> to form a localized section of increased pressure against the inner surface <NUM>.

<FIG> is a perspective view of the adapter <NUM> coupled to the outlet body <NUM>, according to an embodiment. Referring to <FIG>, the adapter <NUM> may be coupled to the outlet body <NUM> by way of releasable engagement between the latch <NUM> and the catch <NUM>, with the closure <NUM> removed from the outlet opening <NUM>. In one embodiment, the adapter opening <NUM> and the outlet opening <NUM> may be axially aligned and extend on a common axis A3 through the coupled assembly adapter <NUM> and the outlet body <NUM>.

The adapter <NUM> may be coupled to the outlet body <NUM> by moving the adapter <NUM> toward the outlet body <NUM>, for example in the axial direction D1, to bring the first collar <NUM> into frictional engagement with the outlet body <NUM> within the outlet opening <NUM>. The latch <NUM> may be moved, for example, in the axial direction D1 in the gap <NUM>. The adapter <NUM> may be rotated to bring the latch <NUM> into interfering contact with one of the peaks <NUM> of the catch <NUM>, thereby increasing resistance to the rotational movement. Continued rotational movement causes the latch <NUM> to deflect as it interferingly moves past the peak <NUM>, and return to its relatively un-deflected condition upon clearing the peak <NUM>. That is, rotation of the latch <NUM> past the peak <NUM> of the catch <NUM> brings the latch <NUM> and the catch <NUM> into an interference or snap fit engagement. The second portion <NUM> of the latch <NUM>, formed as an inward projection, engages the first surface <NUM> of the catch <NUM> to form a mechanical interlock to resist movement in the axial direction D1 of the adapter <NUM> away from the outlet body <NUM>.

In one embodiment, movement of the latch <NUM> into engagement with the catch <NUM>, or vice versa, may provide an audible and/or tactile feedback to the user, in the form of a "click," "pop" or the like, which may be heard and/or felt by the user. Visual feedback may be provided to the user by way of visually inspecting the position of the latch <NUM> relative to the catch <NUM>, for example, by determining that the latch <NUM> is positioned between the peaks <NUM>. Accordingly, a user can confirm that the adapter <NUM> is coupled to the outlet body <NUM> by one or more of an audible, tactile, or visual confirmation.

To remove the adapter <NUM> from the outlet body <NUM>, the adapter <NUM> may be rotated relative to the outlet body <NUM> to disengage the latch <NUM> from the catch <NUM>. During disengagement, the latch <NUM> interfering moves past one of the peaks <NUM> in a manner similar to that described above. With the latch <NUM> positioned in the gap <NUM>, the adapter <NUM> may be moved away from the outlet body <NUM>, the first collar <NUM> may be removed from frictional engagement in the outlet opening <NUM>, and the adapter <NUM> may be removed from the outlet body <NUM>. Audible, tactile and or visual feedback may be provided to the user when removing the adapter in response to the interfering movement of the latch <NUM> out of the catch <NUM>.

<FIG> is a top view of the outlet body <NUM> coupled to the adapter <NUM>, which corresponds to the first condition. Referring to <FIG>, in one embodiment, the adapter opening <NUM> and the outlet opening <NUM> may co-extend on a common axis A3 (shown in <FIG>).

<FIG> shows a drainage tube <NUM> connected to the adapter <NUM>. In one embodiment, the second collar <NUM> (see <FIG>) may be positioned in the drainage tube <NUM> and frictionally engage the tube <NUM>. Preferably, the frictional engagement is a sealed engagement. Alternatively, the adapter <NUM> and drainage tube <NUM> may be connected using other suitable techniques, such as heat sealing, adhesive fastening or mechanical fastening.

Referring to <FIG>, for example, the adapter <NUM> may further include a gripping collar <NUM> positioned axially between the first collar <NUM> and the second collar <NUM>. The gripping collar <NUM> is configured to be gripped by a user to manipulate the adapter <NUM> for example, for rotational and/or axial movement. In one embodiment, the latch <NUM> may extend from the gripping collar <NUM>. The gripping collar <NUM> may have an outer width that is greater than an outer width of the first collar <NUM> and the second collar <NUM>.

<FIG> illustrate an outlet body <NUM> having a closure <NUM> according to another embodiment described herein. The outlet body <NUM> may be formed substantially the same as the outlet body <NUM> described above. Accordingly, further description of like parts of the outlet body <NUM> and the outlet body <NUM> may be omitted below.

<FIG> is a perspective view showing the closure <NUM> frictionally engaged in the outlet opening <NUM> of the outlet body <NUM>, <FIG> is a front view showing the closure <NUM> frictionally engaged in the outlet opening <NUM> of the outlet body <NUM>, and <FIG> is a front transparent view showing the closure <NUM> frictionally engaged in the outlet opening <NUM> of the outlet body <NUM>, according to embodiments described herein.

Referring <FIG>, the closure <NUM> may be a two-part closure. For example, the closure <NUM> may include a first plug portion <NUM> (see <FIG>) configured to be removably positioned and frictionally engaged in the outlet opening <NUM>. In one embodiment, the first plug portion <NUM> may include one or more ribs <NUM> formed on an outer surface, configured to frictionally engage the inner surface <NUM> of the outlet body <NUM>. The two-part closure <NUM> may also include a first cap <NUM> configured to engage an axial end <NUM> of the outlet body <NUM> when the first plug portion <NUM> is disposed in the outlet opening <NUM>. The first cap <NUM> has a width that is greater than a width of the first plug portion <NUM>. In one embodiment, the first plug portion <NUM> and the first cap <NUM> are formed as a single, continuous piece.

Still referring to the <FIG>, the two-part closure <NUM> may also include a second plug portion <NUM>, optionally formed with one or more ribs <NUM> on an outer surface, and a second cap <NUM>. The second cap <NUM> may have a width that is greater than a width of the second plug portion <NUM>. As more clearly shown in <FIG>, the first plug portion <NUM> and the first cap <NUM> include a closure opening <NUM> extending therethrough. With the first plug portion <NUM> positioned in the outlet opening <NUM>, the closure opening <NUM> is disposed in communication with the outlet opening <NUM> and may receive the contents ostomy pouch <NUM> to drain the contents through the closure opening <NUM>.

The second plug portion <NUM> is configured for removable positioning and frictional engagement in the closure opening <NUM>. In addition, the second cap <NUM> is configured to engage an axial end <NUM> of the first cap <NUM>. In one embodiment, the first cap <NUM> is formed with a recess or seat configured to receive at least a portion of the second cap <NUM>. Preferably the frictional engagement between the first plug portion <NUM> and the inner surface <NUM> of the outlet body <NUM>, and the frictional engagement between the second plug portion <NUM> and the inner surface <NUM> of the first plug portion <NUM> are sealed engagements.

In the embodiments shown in <FIG>, with the first and second plug portions <NUM>, <NUM> positioned in the outlet opening <NUM> and the closure opening <NUM>, respectively, the outlet body <NUM> may be substantially closed and sealed against egress of the contents from the ostomy pouch <NUM>. Accordingly, the ostomy pouch <NUM> may collect and store the discharge from the stoma. One or both of the first and second plug portions <NUM>, <NUM> may be removed from the outlet opening <NUM>, or closure opening <NUM>, respectively, to drain the contents from the ostomy pouch <NUM>.

In one embodiment, the first plug portion <NUM> and the first cap <NUM> may be connected to the outlet body <NUM> by a first flexible member <NUM>, such as a strap or a living hinge. The second plug portion <NUM> and the second cap <NUM> may be connected to the first plug portion <NUM> and the first cap <NUM> with a second flexible member <NUM>, such as a second strap or second living hinge. In one embodiment, the closure member <NUM> may be formed as a single, continuous unit, for example, in a molding process.

<FIG> show the outlet body <NUM> and closure <NUM> together with an adapter <NUM> and drainage tube <NUM>, according to an embodiment described herein. In one embodiment, the adapter <NUM> is formed the same as the adapter <NUM> described above. Accordingly, further description of like parts in the adapter <NUM> and the adapter <NUM> may be omitted below.

<FIG> is a top perspective view of an assembly formed by the outlet body <NUM>, closure <NUM>, adapter <NUM> and drainage tube <NUM>, according to an embodiment, and used in an ostomy collection and drainage system. <FIG> is a front view of the assembly shown in <FIG>, and <FIG> is a transparent view of the assembly shown in <FIG>, according to an embodiment. Referring to <FIG>, the closure <NUM> may be removed from frictional engagement with the outlet body <NUM> so that the contents of the ostomy pouch <NUM> may be drained through the outlet opening <NUM>. The adapter <NUM> may be removably coupled to the outlet body <NUM> in the manner described above with respect to the adapter <NUM> and outlet body <NUM>. That is, in one embodiment, the adapter <NUM> may be coupled to the outlet body <NUM> by way of engagement between the latch <NUM> and the catch <NUM>. The resulting mechanical interlock between the latch <NUM> and the catch <NUM> resists relative axial movement. Frictional engagement of the first collar <NUM> in the outlet opening <NUM> also resists relative axial movement and preferably forms a sealed connection. Further, the second collar <NUM> may be frictionally engaged with the drainage tube <NUM>.

Accordingly, in the embodiments shown in <FIG>, the contents of the ostomy pouch <NUM> may be drained through the outlet opening <NUM> of the outlet body <NUM>, the adapter opening <NUM> of the adapter <NUM> and into the tube <NUM>. The tube <NUM>, at an end opposite to the adapter <NUM>, may be coupled to a high volume bag, such as a night drainage bag (not shown).

<FIG> show the outlet body <NUM> and closure <NUM> together with an adapter <NUM> and a tube <NUM>, according to another embodiment described herein. <FIG> is a top perspective view of an assembly formed by the outlet body <NUM>, closure <NUM>, adapter <NUM> and tube <NUM>, according to an embodiment. <FIG> is a front view of the assembly shown in <FIG> is a transparent view of the assembly shown in <FIG>, according to an embodiment.

Referring to <FIG>, the closure <NUM> may be removed from frictional engagement with the outlet body <NUM> so that the contents of the ostomy pouch <NUM> may be drained through the outlet opening <NUM>. The adapter <NUM> may be removably coupled to the outlet body <NUM> in the manner described above with respect to the adapter <NUM> and outlet body <NUM>. That is, in one embodiment, the adapter <NUM> may be coupled to the outlet body <NUM> by way of engagement between the latch <NUM> and the catch <NUM>, and frictional engagement of the first collar <NUM> in the outlet opening <NUM>. Further, the second collar <NUM> may be connected with the tube <NUM> for example, in frictional engagement, by way of heat sealing, using an adhesive or mechanical fastener, or combinations thereof.

However, in the embodiments shown in <FIG>, the second collar <NUM> and tube <NUM> are sized and shaped for use in conjunction with a Foley catheter. For example, each of the second collar <NUM> and the tube <NUM> have a width, or diameter, that is less than a width, or diameter, of the second collar <NUM> and tube <NUM> in the embodiments above and shown in <FIG>. In addition, with reference to <FIG>, for example, the second collar <NUM> may be formed having one or more sections of variable outer widths, or diameters. For example, each section may have a decreasing width from a first end to a second end.

<FIG> show front, side and bottom perspective views, respectively, of an outlet body <NUM> and closure <NUM> according to another embodiment described herein. Referring to <FIG>, the outlet body <NUM> is configured for connection to the ostomy pouch <NUM> in the manner described above with respect to the outlet body <NUM>. The outlet body <NUM> includes an outlet opening <NUM> configured to receive and allow draining of the contents from the ostomy pouch <NUM>. The outlet opening <NUM> is defined at least in part by the inner surface <NUM> of the outlet body <NUM>. In one embodiment, the outlet body <NUM> is formed with a catch <NUM> configured for removable engagement with a latch, as described further below. In one embodiment, the outlet body <NUM> includes two catches <NUM>. In one embodiment, the outlet opening <NUM> may have a width or diameter W of <NUM> to <NUM>. For example, in one embodiment, the outlet opening <NUM> may have a width or diameter W of <NUM> to <NUM>.

<FIG> are enlarged views showing different perspectives of the catch <NUM>, according to an embodiment. Referring to <FIG>, the catch <NUM> is generally formed as a recess at or near an axial end <NUM> of the outlet body <NUM>, and includes a first portion <NUM> open to the axial end <NUM> and a second portion <NUM> spaced from the axial end <NUM>. In one embodiment, the second portion <NUM> may be spaced from the axial end <NUM> by an arm <NUM>. A guide surface <NUM> may be formed along a portion of catch <NUM>. The catch <NUM> may also include a protrusion <NUM>. In one embodiment, the protrusion <NUM> is disposed in the second portion <NUM>.

In one embodiment, the outlet body <NUM> may include an alignment edge <NUM> on an outer surface. The alignment edge <NUM> may define, for example, a line or curve, and may be formed as an angled or rounded corner, a channel or other external structural feature and/or visible marking. In one embodiment, the alignment edge <NUM> may extend substantially in the axial direction D1. The alignment edge <NUM> may include a first section extending on the outlet body, and a second section extending on the arm <NUM>, aligned with the first section. In one embodiment, the protrusion <NUM> may be aligned with the alignment edge <NUM> as well.

<FIG> are perspective views of an adapter <NUM> configured for removable coupling with the outlet body <NUM> and connection to a drainage tube <NUM>, according to an embodiment. Referring to <FIG>, the adapter <NUM> includes an adapter opening <NUM> extending therethrough, a first inner collar <NUM> around a portion of the adapter opening <NUM>, and a first latch <NUM> having a first base <NUM> and a first lug <NUM>. A first notch <NUM> may be formed on the first latch <NUM>, for example on the first lug <NUM>. The adapter <NUM> also includes a first axial face <NUM> and a first groove <NUM> formed between the first axial face <NUM> and the first lug <NUM>. The adapter <NUM> may also include an adapter guide surface <NUM> and an adapter alignment edge <NUM>. Further, a first radial gap <NUM> may be formed between an outer surface of the first inner collar <NUM> and an inner surface of the first latch <NUM>. In one embodiment, the adapter <NUM> includes two first latches <NUM> which may be similarly formed.

<FIG> is an enlarged bottom view of the closure <NUM> and <FIG> is a bottom perspective view of the closure <NUM>, according to an embodiment described herein. In one embodiment, the closure <NUM> may be substantially identical to the adapter <NUM>, except that the closure <NUM> does not include an opening through which the contents of the ostomy pouch <NUM> may flow. That is, the closure <NUM> does not have a part which corresponds to the adapter opening <NUM>.

Accordingly, in one embodiment, and with reference to <FIG>, <FIG>, the closure <NUM> includes a second inner collar <NUM> and a second latch <NUM> having a second base <NUM> and a second lug <NUM>. A second notch <NUM> may be formed on an inner surface of the second latch <NUM>, for example on the second lug <NUM>. The second lug <NUM> is spaced from a second axial face <NUM> by a second groove <NUM>. The second latch <NUM> may also include a closure guide surface <NUM>. The closure <NUM> may also include a closure alignment edge <NUM> on an exterior surface of the closure <NUM>. The closure alignment edge <NUM> may be formed substantially the same as the alignment edge <NUM> of the outlet body <NUM>. The second inner collar <NUM> and the second latch <NUM> are spaced apart by a second radial gap <NUM>. In one embodiment, a portion of the outlet body <NUM> may be received in the second radial gap <NUM> when the closure <NUM> is coupled to the outlet body.

In one embodiment, the second inner collar <NUM>, the second latch <NUM>, the second base <NUM>, the second lug <NUM>, the second notch <NUM>, the second axial face <NUM>, the second groove <NUM>, the closure guide surface <NUM>, the closure alignment edge <NUM> and the second radial gap <NUM> of the closure <NUM> correspond, respectively, to the first inner collar <NUM>, the first latch <NUM>, the first base <NUM>, the first lug <NUM>, the first notch <NUM>, the first axial face <NUM>, the first groove <NUM>, the adapter guide surface <NUM>, the adapter alignment edge <NUM> and the first radial gap <NUM> of the adapter <NUM>. That is, the parts of the closure <NUM> described above may be formed having substantially the same size, shape and relative positioning, for example, as the corresponding parts on the adapter <NUM>. Accordingly, the adapter <NUM> and the closure <NUM> may be interchangeably coupled to the outlet body by engagement of the first latch <NUM> or second latch <NUM> to the catch <NUM>.

<FIG> show different views of the adapter <NUM> coupled to the outlet body <NUM> according to an embodiment. Referring generally to <FIG>, the adapter <NUM> may be coupled to the outlet body <NUM> by moving the first latch <NUM> into engagement with the catch <NUM>. For example, the latch <NUM> may be moved into a friction or interference fit engagement with the catch <NUM>, and also form a mechanical interlock to restrict axial movement of the adapter <NUM> relative to the outlet body <NUM>.

In one embodiment, the adapter <NUM> may be moved toward the outlet body <NUM>, in the axial direction D1 for example, to position the first base <NUM> in the first portion <NUM> of the catch <NUM>. The respective guide surfaces <NUM>, <NUM> may be moved into contact with another, and such contact may cause rotation of the adapter <NUM> relative to the outlet body <NUM>. Alternatively, the user may manually rotate the adapter <NUM> relative to the out body <NUM>.

Movement of the adapter <NUM> toward the outlet body <NUM> positions the first inner collar <NUM> is in the outlet opening <NUM>. In addition, the first lug <NUM> is clear of the arm <NUM> and moved past the arm <NUM>. Rotation of the adapter <NUM>, referred to above, causes first lug <NUM> to move into the second portion <NUM> of the catch <NUM>. The first notch <NUM> is configured to engage the protrusion <NUM> in a friction or interference fit. In addition, the arm <NUM> is received in the first groove <NUM> to form the mechanical interlock. The adapter <NUM> may be coupled to the outlet body <NUM> in the first condition.

The adapter <NUM> may be removed from the outlet body <NUM> by rotating the adapter <NUM> relative to the outlet body <NUM>, or vice versa, to disengage the first notch <NUM> from the protrusion <NUM>. Accordingly, the first lug <NUM> may be moved out of the second portion <NUM> and out of the mechanical interlock with the arm <NUM>. The adapter <NUM> may then be moved away from the outlet body <NUM>, for example in the axial direction D1, and the first collar <NUM> may be removed from the outlet opening <NUM>.

In the embodiments above, an audible, tactile and/or visual feedback may be provided to the user to confirm coupling of the adapter <NUM> to the outlet body <NUM> by way of engagement of the first latch <NUM> and the catch <NUM>. For example, in one embodiment, the first notch <NUM> and the protrusion <NUM> may be brought into a friction or interference fit to provide an audible or tactile "click," "pop," or the like which may be heard or felt by the user. Visual feedback and confirmation may be provided by aligning of the alignment edge <NUM> and the adapter alignment edge <NUM>. Conversely, similar feedback may be provided to the user when removing the adapter <NUM> from the outlet body <NUM>, in response to disengagement of the first notch <NUM> from the protrusion <NUM>, and respective alignment edges <NUM>, <NUM> being moved out of alignment with one another.

In one embodiment, the closure <NUM> may be coupled, interchangeably with the adapter <NUM>, to the outlet body <NUM>, by way of engagement between the second latch <NUM> and the catch <NUM>. As detailed above, the closure <NUM> is formed similarly to the adapter <NUM>, except that the closure is closed (i.e., does not have an opening extending therethrough) to prevent or limit egress of the contents from the pouch through the outlet opening <NUM>. Accordingly, the closure <NUM> may be coupled to the outlet body <NUM> in substantially the same manner as the adapter <NUM> described above.

For example, in one embodiment, the closure <NUM> is moved toward the outlet body <NUM> to position the second inner collar <NUM> in the outlet opening <NUM> and the second base <NUM> in the first portion <NUM> of the catch <NUM>. The closure <NUM> may be rotated, for example, by way of continued movement toward the outlet body <NUM> and contact between the respective guide surfaces <NUM>, <NUM>, or by manual rotation. Rotation of the closure <NUM> moves the second lug <NUM> into the second portion <NUM> of the catch <NUM>. The second notch <NUM> may engage the protrusion <NUM> in a friction or interference fit and provide audible and/or tactile feedback in response to such engagement. The second lug <NUM> also forms a mechanical interlock with the arm <NUM> received in the second groove <NUM> to restrict movement of the closure <NUM> away from the outlet body <NUM> when coupled to the outlet body <NUM>. Visual confirmation of coupling between the closure <NUM> and the outlet body <NUM> may be provided by alignment of the respective alignment edges <NUM>, <NUM> on the outlet body <NUM> and the closure <NUM>, respectively.

Referring to the transparent views shown in <FIG>, the drainage tube <NUM> may be coupled to the adapter <NUM> to connect the ostomy pouch <NUM>, outlet body <NUM> and adapter <NUM> to a high-volume collection pouch, such as a night drainage bag (not shown). The tube <NUM> may be connected to the adapter <NUM>, for example, by friction fit, heat sealing, adhesive, a mechanical fastener, combinations thereof or other suitable techniques.

<FIG> is a top perspective view of the outlet body <NUM> coupled to drainage tube <NUM> via the adapter <NUM>. As shown in <FIG>, the outlet opening <NUM> is disposed in communication with the adapter opening <NUM> and the drainage tube <NUM> to allow for flow of the contents from the ostomy pouch <NUM> through the outlet body <NUM>, adapter <NUM> and drainage tube <NUM>, for example, to a high-volume collection pouch.

Referring again to <FIG>, the closure <NUM> is removably coupled to the outlet body <NUM> to selectively open and close the outlet body <NUM>, and in turn, the ostomy pouch <NUM>. With the closure <NUM> coupled to the outlet body <NUM> (i.e., the second condition) the outlet body <NUM> and ostomy pouch <NUM> are in a closed condition such that the ostomy pouch <NUM> may collect and store stoma discharge as contents within the internal collection area, and unintended egress of the contents is substantially prevented or limited by way of the closure <NUM>. The closure <NUM> may be removed from the outlet body <NUM> to allow for emptying or drainage of the ostomy pouch <NUM> through an outlet body <NUM>.

The closure <NUM> and adapter <NUM> may be interchangeably coupled to outlet body <NUM>. Thus, adapter <NUM> may be removably coupled to the outlet body <NUM> when the closure <NUM> is not coupled to the outlet body <NUM>. The adapter <NUM> may be connected to the drainage tube <NUM> to allow for drainage of the contents of the ostomy pouch <NUM> through the outlet body <NUM>, adapter <NUM> and drainage tube <NUM> to, for example, a high-volume collection pouch, such as a night drainage bag.

<FIG> further illustrate the outlet body <NUM>, closure <NUM>, adapter <NUM> and drainage tube <NUM> shown in <FIG>. <FIG> is a perspective view of the adapter <NUM>. The adapter <NUM> may include an adapter opening <NUM> and a first latch <NUM>. In one embodiment, the first latch <NUM> is generally formed as a recess having a first shoulder <NUM> therein. The recess may be open at a top surface of the adapter <NUM> and a second surface, adjacent to the top surface and extending at an angle relative to the top surface so as to intersect a direction of rotation of the adapter <NUM> when coupling the adapter <NUM> to the outlet body <NUM>. The adapter <NUM> also includes an adapter alignment edge <NUM>.

<FIG> is a perspective view of the outlet body <NUM>, according to an embodiment. The outlet body <NUM> includes, for example, an outlet opening <NUM>, through which the contents of the ostomy pouch <NUM> may be drained. The outlet body <NUM> also includes a catch <NUM>. In one embodiment, the outlet body <NUM> may include two catches <NUM>. The catch <NUM> may have a foot <NUM> at a free end thereof. The outlet body <NUM> also includes an alignment edge <NUM>.

<FIG> is a top view of the closure <NUM>, according to an embodiment. The closure <NUM> may be formed substantially the same as the adapter <NUM>, except that the closure <NUM> is formed with a plug <NUM> and cap <NUM> instead of an adapter opening <NUM> extending therethrough. Accordingly, the closure <NUM> may be coupled to the outlet body <NUM> to substantially prevent or limit egress of the contents from the ostomy pouch <NUM> through the outlet body <NUM>. In one embodiment, the closure <NUM> includes a second latch <NUM> formed as a recess having a second shoulder <NUM>. The closure <NUM> may also include a closure alignment edge <NUM>. In one embodiment, the closure <NUM> includes two second latches <NUM>. In one embodiment, the second latch <NUM> and shoulder <NUM> may be configured substantially the same as the first latch <NUM> and first shoulder <NUM>, respectively. In one embodiment, the plug <NUM> is configured to frictionally engage the outlet body <NUM> within the outlet opening <NUM>. Preferably, the frictional engagement between the plug <NUM> and the outlet body <NUM> is a sealing engagement.

In one embodiment, the second latch <NUM> and the second shoulder <NUM> may be formed having substantially the same, or the same size, shape and relative position on the closure <NUM> as the first latch <NUM> and the first shoulder <NUM> on the adapter <NUM>. Accordingly, the closure <NUM> is configured for removable coupling to the outlet body <NUM> in substantially the same manner as the adapter <NUM>, as described further below.

<FIG> is an exploded view of the closure <NUM> and the outlet body <NUM> of <FIG>, and <FIG> shows the closure <NUM> coupled to the outlet body <NUM>. Referring to <FIG> and <FIG>, to couple the closure <NUM> to the outlet body <NUM>, the second latch <NUM> is held at a position rotationally offset from the catch <NUM> with the plug <NUM> generally aligned with the outlet opening <NUM>. The closure <NUM> may then be moved toward to the outlet body <NUM>, or vice versa, for example in the axial direction D1, such that the plug <NUM> is received in the outlet opening <NUM>. The closure <NUM> may be rotated relative to the outlet body <NUM> to move the second latch <NUM> into engagement with the catch <NUM>. In one embodiment, the second latch <NUM> and the catch <NUM> engage one another. For example, the second shoulder <NUM> may engage the foot <NUM> in a friction or interference fit. The foot <NUM> and shoulder <NUM> may be sized and shaped such that an audible and/or tactile "click," "pop" or the like may be provided when the closure <NUM> is coupled to the outlet body <NUM> in response to the engagement of the second latch <NUM> and the catch <NUM>.

Further, in one embodiment, visual confirmation of coupling may be provided by alignment of the alignment edge <NUM> of the outlet body <NUM> and the closure alignment edge <NUM> of the closure <NUM>.

To remove the closure <NUM> from the outlet body <NUM>, the closure <NUM> may be rotated in an opposite direction to that above, such that the second latch <NUM> is moved outward from the catch <NUM>. Disengagement of the second latch <NUM> from the catch <NUM>, for example, disengagement of the second shoulder <NUM> and foot <NUM>, may provide an audible and/or tactile "click," "pop" or the like. In addition, the rotation may move the alignment edge <NUM> out of alignment with the closure alignment edge <NUM>, thereby providing visual confirmation that the closure <NUM> is no longer coupled to the outlet body <NUM>. The closure <NUM> may then be moved away from the outlet body <NUM>, for example in the axial direction D1, to remove the plug <NUM> from the outlet opening <NUM>.

<FIG> is a perspective view showing the adapter <NUM> and drainage tube <NUM> positioned relative to the outlet body <NUM>, with the closure <NUM> coupled to the outlet body. The closure <NUM> may be removed from the outlet body <NUM> in the manner discussed above. The adapter <NUM> may then be coupled to the outlet body <NUM>.

Accordingly, in the embodiments above, a frictional engagement or interference fit between the latch or the second latch and the catch allows for additional security and retention when the adapter or closure is coupled to the outlet body. For example, the adapter or the closure may have increased resistance to rotation out of a coupled condition due to the engagement of that latch or the second latch and the catch. In addition, the engagement of the latch or the second latch and the catch may form a mechanical interlock which resists movement of the adapter or the closure away from the outlet body, for example, in a substantially axial direction. Thus, the closure and adapter may be less susceptible to inadvertent removal from outlet body.

In addition, engagement of the latch or the second latch and the tab may provide audible and/or tactile feedback to the user to confirm that the adapter or closure is properly coupled to the outlet body, such that the adapter or closure is less susceptible to inadvertent removal from the outlet body. Conversely, audible and/or tactile feedback may be provided to the user when the latch or the second latch and the tab become disengaged. Further, the outlet body, the adapter and/or the closure may include external structural features which are moved into alignment with one another when the adapter or closure are properly coupled to the outlet body, thereby providing visual feedback of proper coupling. Conversely, the structural features may be moved out of align member when the adapter or closure is moved from the proper coupling position.

Although only referred to and discussed with reference to the embodiments shown in <FIG> and <FIG>, it is understood that the outlet opening of the various embodiments above may have a width or diameter W of <NUM> - <NUM>. For example, in one embodiment, the outlet opening may have a width or diameter W of <NUM> - <NUM>.

Referring to FIGS. <NUM>-<NUM>, an outlet body <NUM> with a closure <NUM> tethered thereto according to an embodiment is shown. <FIG> is a perspective view showing the outlet body <NUM> attached to an ostomy pouch <NUM> and an adapter <NUM> coupled to the outlet body <NUM>. The ostomy pouch <NUM> is connected to a night drainage bag <NUM> via a drainage tube <NUM>, which is attached to the adapter <NUM> at one end and to the night drainage bag <NUM> at the other end. The outlet body <NUM> and the adapter <NUM> may be formed substantially the same as the outlet body <NUM> and the adapter <NUM> described above. Accordingly, further description of like parts of the outlet body <NUM> and the outlet body <NUM> and like parts of the adapter <NUM> and the adapter <NUM> may be omitted below.

In this embodiment, the outlet body <NUM> may include a docking system configured to hold the closure <NUM> in place when the closure <NUM> is not engaged in an outlet opening <NUM> of the outlet body <NUM>. The docking system may be configured to dock the closure <NUM> at a fixed place away from the outlet opening <NUM>, such that the closure <NUM> does not interfere with draining of body waste collected in the ostomy pouch <NUM> through the outlet opening <NUM>.

<FIG> are various views of the outlet body <NUM> comprising the docking system including a first docking part <NUM> and a second docking part <NUM> according to an embodiment. In this embodiment, the first docking part <NUM> may be provided on the outlet body <NUM>. The first docking part <NUM> may be formed as a handle like projection, which extends generally radially outward from the outlet body <NUM> to provide an opening <NUM> for receiving the second docking part <NUM>. The second docking part <NUM> may be provided on a flexible member <NUM>, which connects the closure <NUM> to the outlet body <NUM>. The second docking part <NUM> may be configured as a tab like projection extending from a side surface of the flexible member <NUM>. To dock the closure <NUM>, a user may grab the closure <NUM> and manipulate the flexible member <NUM> to insert the second docking part <NUM> into the opening <NUM> defined in the first docking part <NUM>. The first and second docking parts <NUM>, <NUM> may be configured to fixedly hold the closure <NUM> away from the outlet opening <NUM>.

In other embodiments, the first and second parts of the docking system may be provided in various different forms, wherein the first and second docking parts are configured to engage with each other to dock the closure <NUM> proximate the outlet body <NUM> away from the outlet opening <NUM>. For example, the first and second docking parts may be provided as hook and loop fasteners, latch and catch, or other known mechanical or adhesive coupling systems.

Various features of the embodiments above may be used together with or replace other features of different embodiments above.
