Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to the field of sculptural products, and more particularly, to a coupling for detachably attaching a sculpting bag to a pad or disk-shaped member (wafer) attached to the body. The term fistula is here intended to be broadly interpreted and includes colostomy, urine fistula formation, and ileostomy.
[0002]
The present invention, in one form thereof, relates to a so-called two-piece coupling that is constituted by substantially two coupling members, a bag side coupling member and a body side coupling member.
[0003]
DISCLOSURE OF THE INVENTION
Flat mating coupling
There are many different configurations (designs) for two-piece coupling. Typically, the body side coupling member and the bag side coupling member that are engaged with each other form a dead space between the bag and the body pad or the disk-shaped member (wafer). In other words, the bag will be held away from the pad by a distance corresponding to the height of the coupling. In general, it is desirable for the coupling member to have a low profile (contour, shape, longitudinal section), so that dead space is kept to a minimum.
[0004]
In US Pat. No. 4,872,869, one coupling is proposed. In this coupling, the bag is flat-fitted or almost flat-fitted with the body side pad. Such a configuration will be referred to herein as a planar mating coupling.
[0005]
In a broad concept, according to a first aspect of the present invention, a planar mating coupling is provided comprising a body side coupling member and a bag side coupling member that can be secured together.
[0006]
This coupling preferably comprises one or more features as described below.
[0007]
1. The body side coupling member includes an inner first wall and an outer second wall, and a connection channel is formed between the first wall and the second wall. Then, one of the first wall and the second wall is provided with or supports a locking projection facing the inside of the channel. The other surfaces of the first wall and the second wall form a substantially smooth sealing surface (sealing surface).
[0008]
Such a configuration provides significant technical advantages over the prior art.
[0009]
In particular, in the coupling described in the above-mentioned U.S. Pat. No. 4,872,869, the feature is the locking profile of both cylindrical walls forming the body-side coupling member channel. . This locking profile acts in combination with the central rib so that the connecting part of the body side member is captured in the channel. The overlapping region (combination region) has two functions, a sealing function and a fixing function.
[0010]
However, in creating the present invention, it has been understood that a user may have a major problem when trying to separate the bag from the body part by releasing the coupling according to the prior art. This problem arises because the connecting part of the body side member is overlapped with both walls forming the channel and is expanded by the ribs in the channel. This can make it practically difficult to pull the connecting part back from the channel without twisting or deforming the channel to some extent. The above problem becomes a big problem because the coupling is retracted in the bag. Even if the front flange of the bag side coupling member is bent, it is not easy to release both channel walls. This is because the configuration of the recess of the coupling member means that its front flange is not directly connected to the base (base) of the channel.
[0011]
Thus, such couplings require considerable sophistication to release and often present a variety of problems for a large number of people who are elderly and have artificial heels that do not force fingers. It will be.
[0012]
However, according to the present invention, a sealing function (inner first wall or outer second wall) and a locking function (locking function) are realized by forming different wall portions. A number of problems can be avoided. This coupling can be released very easily without weakening its seal (sealing) and without compromising the security of the coupling.
[0013]
Preferably, the wall that supports the locking protrusion supports a plurality of locking protrusions. For example, the plurality of locking projections may be spaced apart from above the angle.
[0014]
In a particular aspect closely related to the present invention, a planar mating coupling is provided as follows.
[0015]
That is, this coupling has a bag side coupling member and a body side coupling member. The bag side coupling member includes an inner first wall and an outer second wall, and a channel is formed between the first wall and the second wall. The bag side coupling member includes a mounting flange that extends outwardly from the second wall at the mouth of the channel. Then, one of the first wall and the second wall includes at least one locking protrusion that faces the first wall.
[0016]
On the other hand, the body side coupling member includes a protrusion that is received during use in a channel of the bag side coupling member. The protrusion includes a forming portion for overlapping and engaging with one locking protrusion of the wall of the bag side coupling member. Further, the bag side coupling member includes a deflectable (flexible) seal for engaging with the other wall of the bag side coupling member without overlapping.
[0017]
2. The bag side coupling member is fixed to the bag making bag. The said bag making bag is provided with the 1st and 2nd bag wall, and is provided with an entrance opening in the 1st bag wall. The bag side coupling member is supported by the first bag wall at the opening. And at least one part of a bag side coupling member is extended in a bag. Non-sealing means is provided, so that a part of the bag-side coupling member and the inner surface of the second bag wall are not sealed during use.
[0018]
This feature of the present invention has the potential, for example, that when the bag is used for the first time, the front wall of the bag located on the opposite side of the coupling member will stick to the coupling member. Make it possible to avoid problems. This effect is similar to the problem of pancaking, where the front and rear walls of the bag sometimes stick together, preventing the body's waste from entering the bag. The use of a coupling member that extends at least partially within the bag, in effect (by holding the wall some distance away), effectively between the front wall and the rear wall at the opening. It is possible to reduce the effect of pancakes. However, there is a potential problem that the bag wall seals the coupling member and easily sticks to the coupling member. This will again prevent the entry of bodily waste into the bag. However, by using the non-sealing means according to this aspect of the invention, this potential problem can be avoided or at least reduced.
[0019]
The non-sealing means may comprise a non-planar surface of the coupling member, such as one or more protrusions or recesses, or a relief surface, whereby the surface of the coupling member and the bag wall A channel or space is more reliably formed between the opposite surface. Optionally, the non-sealing means can comprise a non-stick coat (non-stick coat) supported by a coupling member or bag wall.
[0020]
The present invention, in a closely related aspect, provides a bag side coupling member for a planar mating coupling. The bag-side coupling member has a connection groove (channel) and non-sealing means provided on the back surface of the connection groove (channel).
[0021]
3. The bag side coupling member is supported by the bag making bag. The iron making bag includes first and second bag walls. The first bag wall is provided with an entrance opening, and the bag side coupling member is supported by the first bag wall of the opening. At least a portion of the bag side coupling member extends into the bag, and the surface of the bag side coupling member faces a second wall that is substantially non-planar.
[0022]
In addition to the non-sealing effect, this feature can improve the area where the user can feel the coupling member profile through the bag wall material by hand, which allows the user to When fitting (adapting) or removing the bag from the body, one's hand can be positioned in a better position.
[0023]
In the creation of the present invention, it has been understood that the coupling is considerably hidden from the user's view due to the nature of the recess of the bag-side coupling member that is plane-fitted. This invisibility can make it more difficult to fit and remove the coupling. Therefore, the invisibility of the coupling member can be compensated by improving the tactile properties of the coupling through the second bag wall.
[0024]
In one preferred embodiment, the surface may have a plurality of protrusions spaced apart from each other, for example, a small crest (small dome shape). In other embodiments, the surface can comprise an annular protrusion.
[0025]
The present invention, in a closely related aspect, provides a bag side coupling member for a planar mating coupling. This bag side coupling member has a connection channel (coupling channel). The surface of the coupling member is formed in a direction away from the opening of the channel and is substantially non-planar. This allows the surface to be touched by hand through the bag wall.
[0026]
4). The bag side coupling member includes a channel formed by the first and second wall portions, and a base portion (base portion) positioned between the first and second wall portions. In this configuration, at least one of the portions includes a region having a reduced thickness.
[0027]
According to this aspect of the present invention, the reduced thickness region provides a natural hinge action, so that when the bag side coupling member is assembled to the body side coupling, Alternatively, when the bag side coupling member is separated from the body side coupling, the region in which the channel extends (expands) becomes large.
[0028]
In creating this aspect of the invention, it has been understood that the channel-fitting channel-side coupling member channel is conceptually more problematic than the outer coupling member. This is because, as described above, in a concave structure, the channel is supported around the mouth rather than around the base. This means that the channel is stiffer and does not open as well as the channel supported by its base. Furthermore, in a recessed structure, the channel cannot be accessed. When the bag side coupling member and the body side coupling member have to be released, it is generally more difficult to bend the recessed channel.
[0029]
However, by using the above aspect of the present invention, the region where the channel can be widened can be enlarged, and the above problems can be substantially alleviated.
[0030]
Preferably, the first wall and / or the second wall of the channel comprises a region with reduced thickness. In a preferred embodiment, the first wall portion and / or the second wall portion is formed in a tapered shape so as to become thinner toward the base portion. In addition or alternatively, the base may comprise one or more recesses. With this configuration, the flexibility of the base of the channel can be increased.
[0031]
5). The bag side coupling member is fixed to the bag making bag. The said bag making bag is provided with the 1st wall and the 2nd wall, and the entrance opening is provided in the 1st wall. The bag side coupling member is supported by the first wall in the opening. The bag side coupling member includes a channel, and at least a portion of the channel extends into the bag. The channel is formed by a substantially concentric outer wall and an inner wall. In this configuration, the inner wall protrudes from the inside of the bag through the opening to the outside. The inner wall is swollen (than the outer wall) with respect to the outer wall.
[0032]
With this feature, there is a step (step) in the relative height between the inner wall and the outer wall. Preferably, the outer wall supports or includes at least one locking protrusion. Preferably, the inner wall is formed with a flat sealing surface (sealing surface).
[0033]
This feature of the present invention provides a concave coupling with a relatively large wall for sealing with the body side coupling member without substantially increasing the depth of the coupling member in the bag. Can do. It will be appreciated that it would not be desirable to have too large a coupling depth in the bag. This is because the bag is inflated in the region of the coupling.
[0034]
In a closely related specific aspect, the present invention provides a bag-side coupling member for plane-fitting coupling. The bag-side coupling member includes a mounting flange, a first wall portion depending from the flange, a second wall concentric with the first wall portion and forming a connection channel with the first wall portion. A part. The second wall portion swells (than the first wall portion) with respect to the first wall portion.
[0035]
Coupling seal
Another aspect of the present invention relates to a sealing means for forming a seal between the bag side coupling member and the body side coupling member. The aspect of the present invention can be applied to the plane fitting coupling as well as the non-plane fitting coupling. This viewpoint can be applied to a two-piece coupling, and can also be applied to a multi-piece coupling. It can also be applied to couplings that are mechanically secured together as well as adhesive couplings.
[0036]
There are many different designs of seals. A particularly successful design in mechanical interlock coupling is illustrated in GB 1 571 657. This design includes a cylindrical rib that is received in an annular concave channel. The outer edge of the rib has a contour that interlocks with the inner edge of the wall of the outer concave channel and holds the coupling part in use together. The rib also has an inwardly inclined frusto-cone wiper that forms a seal against the inner wall of the concave channel.
[0037]
The above design has proven to be very reliable in practice. The wiper can be sufficiently deformed to accommodate the tolerance variation and relative motion of the coupling member. However, the minimum coupling “height” achieved is limited by the presence of the wiper and needs to have at least some minimum length. Since this affects the perfect sealing and sealing ability to adapt to size variations, the wiper cannot be made too short.
[0038]
This reduces the dead gap between the ostomy bag and the human body (for non-planar mating coupling) and reduces the bag's (for planar mating and non-planar mating coupling). In general, a low shape is desirable because it reduces protrusions.
[0039]
With reference to GB-A-2567157, an adhesive coupling is disclosed in which the lip extending inside the bag making material is stretched and tightly fitted around the chute of the body side member. This design has a difficult manufacturing problem because it relies on the formation of precisely sized openings in the bag wall. Furthermore, it depends on the exact positioning of the opening and the bag-side coupling member around the opening. Such tolerances require very expensive manufacturing machines for large scale production. A further problem is that the tightness depends on the bag material properties and is not ideal for forming a resilient seal.
[0040]
This aspect of the invention has been devised in view of the above.
[0041]
Compared to the prior art, the current aspect of the present invention is a closed-loop shaped seal fin that normally projects laterally (in at least one operating state, eg, undeformed state) from the wall or chute portion of the coupling member Is to provide. The seal fin is made of an elastic and bendable material and is different from the bag wall.
[0042]
When the wall or chute that supports the fin is on the bag side coupling member, preferably the fin is at least partially offset from an axially offset position relative to the joint between the coupling member and the bag wall material. Extend.
[0043]
This aspect of the invention can provide significant advantages over the following prior art arrangements.
[0044]
(a) Sealability is not limited by the positional accuracy of the coupling member relative to the small hole opening in the bag wall, nor is it limited by the exact size of the small hole opening in the bag wall. Thus, a conventional assembly device with moderate tolerances is used to attach the coupling member to the bag and to make a small hole opening in the bag wall material.
[0045]
(b) Sealability is not limited by the specific nature of the bag wall material.
[0046]
(c) The seal fin is made from a relatively flexible and resilient material. As a result, excellent sealing performance can be obtained with only a small assembly (insertion) force.
[0047]
(d) Coupling members having a very low profile can be made. For example, a smaller insertion depth may be achieved while obtaining a more reliable seal when compared to an integrated frusto-cone bendable wiper.
[0048]
(e) Due to the flexibility of the fins, wide dimensional tolerances can be accommodated compared to the case of some prior art designs without reducing sealing. Preferably, the body side and bag side coupling members are such that the fins projecting from the chutes on the members are engaged with the other coupling members relative to the surface of the second chute wall (ie, the cylindrical wall). Configured to match. Preferably, when the coupling members are assembled together, the chute fits into one inside the other.
[0049]
The fins can be provided on the bag side coupling member or on the body side coupling member.
[0050]
If desired, the coupling member may include one such fin, two fins, or more fins.
[0051]
Coupling members including fins may be created by various techniques. The embodiment includes the following steps.
[0052]
(a) Multi-shot (for example, two-shot) molding.
[0053]
(b) Injection molding (similar to multi-shot molding, but with this technique the plastic material can be set before the next plastic material is molded).
[0054]
(c) Manufacturing using a plurality of preformed components that are sequentially assembled to form the finish member was held in its assembled state by mechanical interlocking, gluing, or welding.
[0055]
(d) Integrated molding of a member made of a flexible polymer using, for example, injection molding.
[0056]
Another related aspect of the present invention is the use of one or more sealing elements supported on the first wall of the coupling and extending or projecting generally radially from the first wall of the coupling. The one or more sealing elements are formed from a plastic material that is more flexible than the material of the first wall.
[0057]
In preferred shapes, the one or more sealing elements typically extend or protrude radially, at least in a non-curved state (eg, when the coupling member is separated).
[0058]
Typically, a combination of a radially extending or protruding seal and a sealing material that is usually more flexible than the structural part of the coupling allows a low coupling profile to be achieved without compromising hermeticity. .
[0059]
Such a design is particularly suitable for two-piece mechanical interlock couplings, but is used in many other coupling types, for example, those with a locking ring or those that are secured together by gluing Suitable for that.
[0060]
Preferably, the one or more sealing elements are integrally formed with the first wall. For example, an injection molding process or a multi-shot molding process can be used. Reference is made to the technology described in GB-A-2 323 285.
[0061]
Preferably, in any of the above aspects, the at least one sealing element or fin is axially beyond the cylindrical band or region, rather than forming a so-called “dot seal” at only one axis point. Form a spreading seal. By spreading the seal in the axial direction, the seal can withstand relative movement or distortion of the coupling member without compromising complete sealing. Preferably, the at least one sealing element or fin is in the form of a wiper that can be bent to some degree in contact with the opposing coupling member. Such curvature allows the sealing element to be securely mounted on the opposing surface with a moderate but sufficient force to achieve a seal. Preferably, a wider range (cylindrical band) seal as described above can be achieved.
[0062]
Preferably, at least one sealing element or fin tapers towards its free edge.
[0063]
Preferably, the at least one sealing element or fin is different from the material of the bag making bag. Preferably, the sealing element is on a surface offset from the surface of the bag making material.
[0064]
If desired, the one or more sealing elements can project radially inward from the first wall of the coupling member. However, within a particularly preferred shape of the invention, one or more sealing elements protrude radially outward from the cylindrical ribs of the coupling member. Such designs can be more easily shaped when multiple sealing elements are used.
[0065]
In a closely related aspect, the present invention is a first used in a two-piece sculptural coupling of the type including first and second coupling members removably secured together by a mechanical interlock. A coupling member is provided. The first coupling member comprises a first portion made of a first relatively stiff plastic material integrally formed with a second portion made of a second relatively soft plastic material. A locking contour is provided to form a mechanical interlock with the second coupling member, and the second portion is provided with a sealing element.
[0066]
In a closely related aspect, the present invention provides a first coupling member for use in a type of coupling that includes first and second coupling members that are mechanically secured together. The first coupling member includes at least one normally annular seal fin that protrudes generally radially from the cylindrical wall. The fin tapers towards its free edge.

DETAILED DESCRIPTION OF THE INVENTION
As shown in FIGS. 1 to 4, the two-piece ostomy coupling 10 is generally composed of a body side coupling member 12 and a bag side coupling member 14.
[0069]
The bag side member 14 includes a flange 16. In this embodiment, the flange 16 is attached to the outer surface of the bag wall 18 by adhesion, welding, or other suitable fixing method. However, as will be described further below, the flange 16 can be attached to the inner surface of the wall 18 if desired. The flange 16 has a small hole aligned with a corresponding opening 20 in the bag wall 18. Independent of the inner edge of the flange 16, a cylindrical outer wall 22 extends rearward in the bag, and a cylindrical inner wall 24 is disposed concentrically with the outer wall 22. The inner wall 24 and the outer wall 22 form a connecting concave channel and are joined together by a floor 26 of the concave channel. The positioning rib 28 protrudes from the floor portion 26 so as to be smaller than the inner wall and the outer wall. In this embodiment, the positioning ribs 28 have a generally tapered shape, but it will be understood from the following description that other shapes of the ribs 28 may be used as desired.
[0070]
Similar to the extension of the front flange 16, it can be provided with a number of radially projecting belt tabs and / or pull tabs 32 that can be securely clamped to the flange 16 as described below.
[0071]
The concave channel floor 26 includes a radially outer portion 26 a between the rib 28 and the outer wall 22, and a second radially inner portion 26 b between the rib 28 and the inner wall 24. The radially inner portion 26b is described in WO-A-93 / 23229 and, as will be described below, in this embodiment, a plurality of regularly spaced indentations to facilitate molding of the coupling member. 30 is included.
[0072]
On its inner surface, the outer wall 22 supports a plurality of spaced apart protrusions 34. These serve to form the corresponding structure and interlock structure of the body side member. Each projection 34 includes a substantially flat or undercut rear surface 36 and an upper ramp surface 38.
[0073]
As disclosed in WO-A-93 / 23229, during production of the bag-side coupling member, the spacing between the protrusions 34 is such that the portion of the mold tool (not shown) under the protrusions 34 is its space. By allowing the tool to be removed from the inside of the concave channel by rotating the tool relative to the coupling member (or vice versa) until the part of the mold tool can be withdrawn. The indent is keyed with the molded member and allows controlled rotation.
[0074]
The body side member 12 includes an annular flange 40. An annular flange 40 is attached to an adhesive “wafer” or pad 42 for attachment to human skin. The pad 42 may be made from stomadhesive or other known skin adhesives. Such adhesives are well known to those skilled in the art and will not be described further here.
[0075]
The flange 40 includes a small hole 44. The small hole 44 is bounded by a substantially annular structure 46 formed to fit within the concave channel of the bag side member. The structure 46 includes a radially outer locking rib 48 for mating between the outer wall 22 and the positioning rib 28 of the bag side member 14. The locking rib 48 includes a generally rounded or tapered tip 50 and a stepped or undercut locking structure 52 for cooperating with the protrusion 34. This structure also includes a seal wiper 54 directed radially inward to form a seal against the outer surface in the radial direction of the inner wall 24. The wiper 54 can be deformed or deflected at least partially and bends toward its tip beyond its upper end and taper. A generally annular locating groove 56 between the wiper 54 and the lock rib 48 is configured to cooperate with the locating rib 28 as further described below.
[0076]
To assemble the coupling member, the bag side member 14 is positioned relative to the body side member 12 and biased against the body side member. Under very mild pressure, the locking rib 48 can pass over the ramp surface 38 of the protrusion 34 until the protruding snap fits against the locking structure 52 of the locking rib. During such a combination, the fitting usually does not occur simultaneously all around the coupling. Rather, the mating begins in one annular region and proceeds around the coupling, tending to achieve a full circle. By such fitting, the bag side member may be inclined with respect to the axis of the body side member. In this embodiment, the positioning ribs 28 and the positioning grooves 56 act to prevent such tilting and ensure that the bag side member is accurately centered on the body side member 12. To. Since there is no interlock between the wiper 54 and the inner wall 24, the seal wiper 54 can be accurately fitted against the smooth surface of the inner wall 24 to form a reliable seal all around the wall. It will be appreciated that accurate alignment is important.
[0077]
The relative shapes of the positioning ribs 28 and the positioning grooves 56 can be varied as desired. However, the smoothly tapered shape shown is generally preferred for ease of molding and optimal guidance during assembly of the coupling member.
[0078]
In the assembled state (as shown in FIG. 3), the bag is substantially flush with the body pad 42 and there is little wasted dead space between the bag and the body pad 42. . In the preferred embodiment shown, the ribs 28 are sized as required relative to the positioning grooves 56 so that the ribs 28 do not attempt to separate the locking ribs 48 and the wipers 54. Nevertheless, the fit between the locking protrusion 34 and the undercut 52 of the locking rib 48 provides a reliable fixation to prevent accidental release of the bag.
[0079]
To separate the engaged coupling member, the bag side member 14 is peeled from the body side member 12, for example by grasping and pulling one of the tabs 32. The plastic material of the outer wall 22 of the bag side member 14 can be sufficiently deformed so that it can be released with an appropriate separating force. In particular, the deformation of the inner wall 24 of the bag side member 14 is not required. This is because the inner wall does not interlock with the body side member, and the body side structure 46 is not obstructed by the wall.
[0080]
In the illustrated embodiment, the flange 16 of the bag side coupling member 14 is fixed to the outer surface of the bag wall 18. However, if desired, the flange can be secured to the inner surface of the bag wall (ie, relative to the virtual bag wall 18 ').
[0081]
The coupling member is preferably integrally molded. Suitable plastic materials include, for example, low density and high density polyethylene, thermoplastic elastomer (TPE), polyvinyl chloride (PVC), acetyl plastic, ABS, polyamide, and any combination thereof. For example, different plastics may be used in the two coupling members to provide one with generally hard or rigid properties and the other with more bendable properties. The material may also be used depending on, for example, the weldability of the material to the bag wall for the bag side coupling member and the adhesive wafer laminate for the body side coupling member.
[0082]
5-8 illustrates a modification of the bag side coupling member 70. FIG. Except for the following features, this is the same as the bag-side coupling member 14 of the first embodiment.
[0083]
(a) The positioning rib 28 of the first embodiment is omitted. This means that the complementary structure (46) of the body side coupling member has been simplified by removing the annular positioning groove (56). It will be appreciated that positioning ribs 28 and positioning grooves 56 may be included if desired.
[0084]
(b) The inner wall 24 is longer in the axial direction than the outer wall 22 and protrudes beyond the flange 16. Depending on the thickness of the material, such as the bag wall material, and according to the manner in which the flange 16 is secured to the bag wall, the inner wall 24 may protrude beyond the bag wall.
[0085]
The increased length of the inner wall 24 can improve the ease with which the bag side and body side coupling members are aligned for assembly. It can also provide a large sealing area for the sealing element 54 of the body side coupling member.
[0086]
It will be appreciated that the increased length of the wall 24 does not increase the overall profile height of the coupling, as it matches the length within the bag-side coupling member height.
[0087]
(C) The coupling member 70 supports many collision protrusions 74 on the rear surface 72. As can be seen in FIG. 8, the protrusion 74 serves two functions.
[0088]
First, the protrusion 74 serves as an anti-seal means that reduces the tendency of the plastic coupling member to stick to the back wall 76 of the bag. Such sticking is similar to the well-known problem of pouch pancaking, otherwise it may prevent movement of fecal matter from the bag-side coupling member 70 into the bag. The protrusion 74 (the clearance between adjacent protrusions 74) appears to significantly reduce the sticking problem.
[0089]
Secondly, the protrusion gives an indication of the stereoscopic effect that the user can feel with his / her finger through the bag wall material. Thereby, the range in which the user can feel the shape of the coupling member with the finger through the bag wall material can be expanded, and the user can better arrange the finger when the bag is aligned with the body. It is understood that the concave nature of the bag side-matching coupling member results in a coupling that hides much of the user's field of view, and this loss of field makes it more difficult to align and remove the coupling. I will. Thus, the improved tactile sensation of the coupling through the second bag wall compensates for the loss of visibility of the coupling member.
[0090]
It will be appreciated that the rear non-planar configuration may be used to improve the tactile feel of the coupling through the bag wall. It will also be appreciated that, in addition or alternatively, a non-stick coating may be applied to the rear surface 72 of the coupling 70 or the facing bag wall 76 to provide or enhance a non-stick effect.
[0091]
9 and 10 illustrate a further variation of the bag side coupling member 80. This is very similar to the bag side coupling member 70 shown in FIGS. However, in this example, the inner wall 24 tapers in thickness toward the connection with the floor 26 of the concave channel. This reduced thickness provides a natural hinge effect that improves when the channel is easily opened when bent. This solves the problem that the concave channel does not move smoothly as a result of being supported by the flange 60 extending from the outer wall 22 around the mouth of the concave channel. As a result of not moving smoothly, a large insertion force is required to assemble the bag-side coupling member into the body-side coupling member, and a large peeling force is required to separate the coupling member. There will be things. By providing a natural hinge effect, the inner wall 24 can be bent during assembly or when the bag-side coupling member is peeled off, so that it can be used without compromising the sealing and securing characteristics of the coupling.
[0092]
As shown in FIGS. 11 to 14, the two-piece ostomy coupling 110 is generally composed of a body side coupling member 112 and a bag side coupling member 114.
[0093]
The bag side member 114 includes a flange 116. In this embodiment, the flange 116 is attached to the outer surface of the bag wall 118 by gluing, welding, or other suitable fastening method. However, similar to the first embodiment, the flange 116 can be attached to the inner surface of the wall 118 as desired, as further described below. The flange 116 has a small hole that is aligned with a corresponding opening 120 in the bag wall 118.
[0094]
A cylindrical outer wall 122 extending backwards into the bag from the inner edge of the flange 116 hangs down, and a cylindrical inner wall 124 is disposed concentrically inside the outer wall 122. The inner wall 124 and the outer wall 122 are connected to each other by a floor portion 128 of a concave channel when a concave channel 126 is formed.
[0095]
As will be described below, a plurality of radially projecting belt tabs and / or pull tabs 130 are provided to allow the flange 116 to be securely clamped. To assist in molding the coupling member as well as the indentation 30 of the first embodiment, the floor 128 of the concave channel 126 includes a plurality of regularly spaced indentations 132 in this example. .
[0096]
The inner wall 124 supports a plurality of spaced apart protrusions 134 on its outer surface. These serve to form an interlock with the corresponding configuration of the body side coupling member 112. Each protrusion 134 includes a rear surface 136 that is flat or undercut in a generally planar shape and an upward ramp surface 138.
[0097]
The body side member 112 includes an annular flange 140. The annular flange 140 is attached to an adhesive “wafer” or pad 142 for attachment to human skin. The pad 142 may be made from stomadhesive or other known skin adhesives. Such adhesives are well known to those skilled in the art and will not be described further here.
[0098]
The flange 140 includes a small hole 144. The stoma 144 is bounded by a generally annular structure 146 configured to mate within the recessed channel 126, and a first portion of relatively stiff plastic material and a relatively soft plastic first. 2 parts. The first portion includes a generally cylindrical rib 148 on its inner surface with a locking structure 150 that is stepped or undercut to cooperate with the protrusion 134.
[0099]
The second portion comprises at least one (two in this example) substantially radial sealing fins 152 projecting radially outward from the rib 148. Each fin 152 extends from the base support region 154, extends outwardly from its rib 148, and tapers toward the tip.
[0100]
The fins 152 are dimensioned to be slightly “oversized” to fit within the recessed channel 126. Thus, as can be seen in FIG. 14, when the coupling members 112 and 114 are assembled, the tips of the fins 152 are bent to fit into the inner surface of the wall 122 of the outer concave channel. The bent tip of each fin 152 is thus compared to other types of prior art low side seals that only provide point sealing characteristics by spreading each seal over the cylindrical band in this way. It is possible to achieve very good sealing properties. In particular, this seal achieves the following advantages:
[0101]
(A) It is possible to withstand the movement and bending of the coupling members 112 and 114 that cannot be avoided when worn on the body without losing the integrity.
[0102]
(B) Since the seal portion bends relatively easily, a large insertion force is not required when the two coupling members are combined.
[0103]
(C) Since the seal fin protrudes substantially in the radial direction, the length of each fin does not increase the height of the coupling member. Therefore, a very low coupling member cross section can be achieved. In the illustrated embodiment, a cross-sectional height of less than 5 mm is achieved. It is preferably 4.4 to 4.5 mm or thinner.
[0104]
(D) The seal portion can absorb the variation in the size tolerance of both coupling members. This means that excessively precise tolerances are not required in the production of the coupling member. Therefore, it is possible to reduce manufacturing costs and reduce the occurrence of defective products.
[0105]
(E) As a material to be used for the seal fin 152, a material that maximizes seal characteristics can be selected. And the structural strength of the other part of a coupling member and the connection safety | security of both coupling members are not influenced by the material to select.
[0106]
Since each fin 152 is tapered, any deflection of the fin 152 will occur at the tip portion. As a result, a desirable cylindrical seal can be achieved instead of a point seal. The dimension of the fin 152 is slightly larger than the maximum dimension of the concave groove portion in consideration of the manufacturing tolerance of the coupling member.
[0107]
In the illustrated example, two seal fins are depicted, but the number of fins may be one or three or more as required. When more fins are provided in the illustrated embodiment, it is preferable that the fins protrude outward in the radial direction in consideration of ease of molding.
[0108]
In this embodiment, the seal fin 152 is made of a soft material different from the cylindrical rib 148. Convenient manufacturing techniques for manufacturing a body side coupling member 112 composed of two materials are two-shot molding and insert injection molding. In this embodiment, the base support region 154 provides additional contact area between the hard and soft materials to achieve a strong integral connection during the two-shot molding process. Of course, any suitable manufacturing technique can be used, including assembling individual component parts by hand.
[0109]
A suitable material for rib 148 and flange 140 is STD PVA copolymer. A suitable material for the seal fin 152 is synthetic rubber. Such materials can be selected that are chemically bonded when two-shot molding is performed. When non-adhesive materials are used, mechanical connection means are required.
[0110]
It is preferable to use different materials for the seal fins 152 and the ribs 148, but if necessary, the seal fins 152 and the ribs 148 can be manufactured integrally from the same material (for example, a flexible polymer). Also good.
[0111]
As indicated by a broken line in FIG. 14, the flange 140 of the bag side coupling member 114 may include a mount 160 that is integrally configured to dispose the gas filter 162. The mount 160 may be of a carrier type that can be opened and closed. In this case, the filter 162 can be replaced. The mount 160 may be of a sealed closed type. In the example shown in the figure, the mount 160 has a form in which the flange 140 is extended sideways. However, the mount 160 may take any form. For example, it may be of the satellite type connected to the flange 140 by a web, or may be part of the flange 140. Providing such an integral filter assembly provides another advantage of simplifying manufacturing because the filter can be automatically aligned. Furthermore, the filter and the coupling member can be attached to the bag in one fusing process (not the filter and the coupling member are attached separately).
[0112]
In use, to assemble the coupling members 112 and 114, the structural portion 146 of the body side coupling member 112 is pressed into the recessed groove 126 of the bag side coupling member 114. This pressing can be performed with only a small insertion force. The lock portion 150 forms a snap fit together with the protruding portion 134 of the concave groove inner wall 124. As already described, the seal fin 152 forms a seal against the inner surface of the outer wall of the concave groove by bending.
[0113]
To separate the two coupling members, the user grasps one of the belt tabs / pull tabs 30 and pulls the bag side coupling member 114 away from the body side coupling member 112. Since the bag side coupling member 114 is sufficiently soft, both the coupling members can be peeled off with a slight separation force. However, in normal use while being mounted, the coupling members are firmly connected to each other by the mutual lock of the lock portion 150 and the protruding portion 134.
[0114]
As in the first embodiment, the concave groove outer wall 122 and the concave groove inner wall 124 extend rearward from the front flange 116 of the bag side coupling member. Therefore, the concave groove 126 is recessed toward the inside of the bag. This gives the impression that the bag fits very closely to the adhesive pad 142 and that the coupling is very low because most of the cross-sectional height of the coupling is hidden within the bag. The modified features described in FIGS. 5-10 can be incorporated into specific examples as needed.
[0115]
In another embodiment, the concave groove inner wall 124 and the outer wall 122 may protrude forward from the front flange 116, if desired. In this case, the flange 116 is positioned substantially in the same plane as the bottom 128 of the concave groove 126.
[0116]
In the illustrated embodiment, the flange 140 of the bag side coupling member 114 fits the outer surface of the bag wall. However, in another embodiment, the bag side coupling member is fixed to the inner surface of the bag wall (dashed line in FIG. 12). In such an alternative configuration, an integral filter mount 160 can be used.
[0117]
In the illustrated embodiment, the female coupling member 114 (including the concave groove 126) is positioned on the bag side, and the male coupling member 112 (including the protruding structure portion 146) is positioned on the body side. This is because a male member formed by two-shot molding has a slightly higher manufacturing cost than a female member formed by single-shot molding. In general, since the bag side member is replaced more frequently than the body side member, it is advantageous to use a cheaper coupling member on the side that can be replaced frequently. However, if necessary, the male member and the female member may be interchanged so that the female member is used on the body side and the male member is used on the bag side.
[0118]
FIG. 15 shows a modified embodiment of the coupling 110 ′. Since this modified embodiment is the same as the first embodiment described above, the same reference numerals are used where appropriate. The main difference between the second embodiment is that the seal fin 152 ′ protrudes radially inward, and the lock portion 150 ′ is located at the radially outer end of the structure portion 146 ′. This coupling functions in the same way as in the first embodiment to achieve a reliable seal. Moreover, the cross-sectional height is also low like the case of 1st Embodiment. However, the first embodiment is currently preferred in that it can be easily molded.
[0119]
FIG. 16 shows a three-piece type ostomy coupling 200, which is still another embodiment. This coupling includes a bag-side coupling member 202 and a body-side coupling member 206 that holds an elastic split lock ring 206. The function of the split lock ring is described in British Patent Application Publication (GB-A-2299761), so please refer to it. In brief, the lock ring 206 includes a number of locking tabs 208. The lock tab 208 projects through an opening 210 formed in the body side coupling member 204 and engages with the bag side coupling member 202 to connect the two. The upper end of the tab 208 is tapered so that the bag side coupling member 202 can be snap-fitted. To separate both coupling members, the ring 206 is operated. For example, the ring 206 is rotated and the tab is retracted by a cam action on the end surface (not shown) of the opening 210. When the tab 208 is retracted radially, the bag side coupling member 202 can be separated from the body side coupling member 204.
[0120]
In this embodiment, the body-side coupling member 204 includes annular fins 212 that are substantially radially similar to the above-described fins 152. The fin 212 is made of elastic plastic, and is supported by a base 214 that is integrally molded in the concave portion of the body side coupling member 204. The fin 212 is tapered toward the tip, and forms an elastic seal against the surface 216 of the bag side coupling member 202 when both coupling members are combined. This seal fin provides the same sealing characteristics and advantages as the fin 152 described above. Although only one seal fin 212 is depicted, multiple fins can be used if desired.
[0121]
FIG. 17 shows a three-piece type coupling 220 which is still another embodiment. The coupling 220 in FIG. 17 is the same as the coupling 200 in FIG. 16, but the seal fins 222 are held by the bag side coupling member 224. The body side coupling member 226 includes an inner cylindrical wall 228 that defines a concave groove that receives the bag side coupling member 224. The seal fin 222 is pressed against the cylindrical wall 228 to form an elastic cylindrical band seal. In the illustrated example, one fin 222 is formed to simplify molding, but more seal fins may be formed.
[0122]
Referring to FIG. 18 and FIG. 19, the ostomy bag 310 includes a front wall 312 and a rear wall 314. Both walls are made of a plastic film and are welded to each other at a peripheral seam 316. The rear wall 314 includes a substantially circular hole 318. A bag side coupling member is located at the periphery of the stoma hole 318. The bag side coupling member can be detachably attached to the body side coupling member attached to the body.
[0123]
The bag-side coupling member 320 includes a first annular member 324 fixed to the bag rear wall 314, a second annular member 326, and an annular seal diaphragm 328 sandwiched between the first and second annular members 324 and 326. With. The first and second annular members 324, 326 can be made of plastic or cardboard, for example, and the seal diaphragm 328 can be made of a soft and flexible material. For example, rubber, soft rubber, or soft and flexible thermoplastic elastomer.
[0124]
Each member 324, 326, 328 can be secured to each other by any suitable means. For example, gluing, welding if possible, or mechanical fixation or interlocking.
[0125]
The second annular member 326 includes a layer of adhesive 330, which allows the bag side coupling member 320 to be detachably attached to the body side coupling member 322. The adhesive is preferably one that can be positioned again (also called an adhesive that can be peeled off and resealed). Such adhesives are known to those skilled in the art.
[0126]
The body-side coupling member 322 includes a cylindrical chute 332, and a flange 334 projects from the chute 332 in a generally radial direction. The flange 334 is attached to a pad 336 made of a wafer made of an adhesive that fits the skin. This adhesive is, for example, stomadhesive manufactured by Bristol-Myers-Squibb.
[0127]
Flange 334 provides a mounting surface 338. The adhesive 330 of the bag side coupling member 320 can be attached to the attachment surface 338 of the body side coupling member 322 to fix both coupling members.
[0128]
The outer diameter of the chute 332 is smaller than the inner diameter of the first and second annular members 324 and 326. Thereby, the chute 332 is received inside the two annular members. However, the outer diameter of the chute 332 is larger than the inner diameter of the flexible diaphragm 328. Thereby, the diaphragm 328 is engaged with the periphery of the chute 332 to form a seal.
[0129]
This sealing effect is shown in more detail in FIG. When the bag side coupling member approaches the body side coupling member, the chute 332 forcibly increases the diameter of the opening formed in the diaphragm 328. In addition, the flexible diaphragm material bends toward the stoma 318 in the bag. The diaphragm material easily deforms to accept such expansion and deflection and fits in tension around the chute 332. In this manner, a highly reliable airtight seal can be formed around the chute 332 with only a very small insertion force required to penetrate the chute 332 through the diaphragm 328.
[0130]
When the bag side coupling member 320 is removed from the body side coupling member 322, the chute 332 is easily removed from within the opening of the seal diaphragm 328. The diaphragm 328 returns to a normal flat shape by its own elasticity.
[0131]
FIG. 20 shows a modification of the bag side coupling member 320. In this modification, the annular members 324 and 326 are formed as an integral annular member 324 ′. A flexible diaphragm 328 made of an elastic material is molded integrally with the annular member 324 ′. This molding can be performed using, for example, two-shot molding or insert injection molding. This makes it possible to form a coupling that is integrally formed from two plastic materials.
[0132]
As shown in the figure, the coupling member 324 ′ includes an adhesive layer 330 as in the case of FIG.
[0133]
In yet another form, the coupling member can be integrally molded from a single flexible plastic material. For example, a thermoplastic elastomer is used.
[0134]
FIG. 21 shows yet another embodiment of ostomy coupling. This ostomy coupling is the same as that shown in FIG. 20, except that the seal fin 366 is formed not on the female coupling member but on the male coupling member.
[0135]
The seal fin 366 projects substantially radially from a support 372 made of the same material. The support part 372 is molded integrally with the other part of the male coupling member by a two-shot molding process (or an insert injection molding process). Support 372 provides sufficient contact area between the two materials to achieve a secure bond during the molding process.
[0136]
The outer diameter of the flexible fin 366 is larger than the inner diameter of the female coupling member 380. Thereby, when both coupling members are combined, an elastic seal is formed there.
[0137]
The coupling member in the preferred embodiment is generally circular, although other closed loop shapes can be employed if desired.
[0138]
The foregoing description is merely illustrative of preferred forms of the invention, and it is believed that any modification can be made within the scope or principle of the invention. Features that are believed to be particularly important are set forth in the following claims, whether or not explicitly set forth therein, the novel features or ideas described in this specification and the drawings are protected. I hope that.
