Description

  The present invention relates to ostomy appliances, such as ostomy pouches. In particular, the invention relates to a so-called integrated ostomy appliance in which a formable adhesive body fitting is permanently attached to a pouch.

  Modern ostomy appliances are typically attached to the body using an adhesive wafer. The most commonly used bonded wafers are designed to have a defined fixed shape. The wearer uses a scissors to be cut along the guide line that is pre-printed on a standard size adhesive release sheet to match the size and shape of the wearer's fistula. Cut the center opening.

  In so-called integrated instruments, the adhesive wafer is permanently attached to the instrument to the extent that the adhesive wafer cannot be easily separated without the risk of damaging the instrument. The unitary instrument is intended to be used as an integrated unit. Often, complaints about monolithic devices can always fit the size of the central opening in the adhesive wafer for the elderly, visually impaired, or clumsy people because the device prevents access from one side. It is not easy.

  In so-called two-piece instruments, the adhesive wafer forms part of a separate body equipment component that is attached by a releasable connection. The two-body device allows the body equipment to be separated from the device without damage so that at least one of the components remains functionally usable. For example, the body equipment may remain in place on the body and the replacement pouch may remain seated in the used pouch. Two-piece instruments allow better access to fit wafers, but common complaints about two-piece instruments are always a component for the elderly, visually impaired, or clumsy people It is not easy to match.

  U.S. Pat. No. 6,057,049 describes an improved one-piece or two-piece, including at least a portion of the adhesive that can be manually molded by the wearer to provide a custom fit around the fistula. Describe body ostomy appliances. This alternative method of customizing the wafer offers the possibility of a better fit around the fistula than by a fit that can be obtained by cutting along standard size guidelines. Achieving a good fit is desirable in order to reduce the exposure of the peristomal skin to excreta exiting the fistula. The peristomal skin may be quite sensitive and vulnerable to irritation or infection when contacted by excrement. Excreta exiting the fistula may include digestive fluid from the body, such fluid can also attack the peristomal skin and cause exfoliation. Contact with excrement also gradually reduces the effectiveness of the adhesive. However, the fistula has many different dimensions and shapes. An advantage of the moldable adhesive taught in US Pat. No. 6,099,059 is that the user can mold the adhesive to closely match the exact dimensions and shape of the fistula.

  In the form in which the device of Patent Document 1 is implemented as a two-piece ostomy device, the wearer can mold from both sides, including the non-body contact side, when the pouch is separated from the body equipment. Access to the agent is possible. This can allow the wearer to easily mold the adhesive, for example by folding or rolling from the non-body contact side. However, as illustrated by pouch 20 in FIG. 1 of the accompanying drawings, access is more limited when implemented as a conventional type of integrated instrument. The wearer can only access the moldable adhesive 21 to form the fistula opening from the body contact side 22 rather than the opposite non-body contact side 23 which is covered by the immobile pouch 20. . This makes the molding of the adhesive more difficult and means that the shape and dimensions of the opening may not be as accurate as when the adhesive is accessible from both sides.

  U.S. Patent Nos. 5,099,086 and 5,037,096 use two different types of fixtures extending in complementary first and second angular zones or arcs that extend completely around the fistula opening. An alternative integrated ostomy pouch is described in which a bonded wafer is attached to the pouch. In the first angular zone around the fistula opening, the wafer is permanently attached permanently. In the second angular zone around the opening, the wafer is initially unattached or releasably attachable. The second angular zone allows the pouch to be partially folded by opening the wafer slightly within the restricted area of the second zone and through the gap formed between the wafer and the pouch. Said to be accessible. This access is said to facilitate cutting the adhesive or fitting a separate sealing member or removing and fitting a separate disposable internal pouch. However, such a solution illustrates the unique discrepancy associated with the step of trying to combine the two-part nature with the stationary body fixture of an integrated instrument. With such a solution, the first area, where the body equipment is stationary, hinders access to the body equipment because the pouch cannot fold apart within this area. Unless the second area is made exceptionally large, access to the overall adhesive may still remain limited, making it difficult for elderly or clumsy people to use the instrument. Let me. In addition, considering discontinuities that are inevitable at all of these points, (i) at the point where the first and second areas meet around the periphery of the fistula opening and / or (ii) use There may be a sealing vulnerability between the faceplate and the pouch at the fold notch or crease of the stiffening ring.

  Further manufacturing limitations of the conventional monolithic form of FIG. 1, and the alternative arrangement described in US Pat. In order to extend, it needs to be dimensioned. This shape is believed to exist in all mass-produced monolithic pouches currently available and is a result of the manufacturing technique used. The technique typically uses a pouch to form the peripheral weld 26 and stamp the material after the adhesive 21 has already been installed in its operable position around the inlet opening 27. A clearance is required for intimate contact with the material for the walls 24,25. The pouch 20 typically extends significantly below the inlet opening 27 to provide the main collection volume of the pouch 20, so this shape does not interfere with the lower portion of the pouch. However, the need for the pouch 20 to also extend above and / or on either side of the adhesive 22 results in unused headspace 28. Such a headspace 28 is undesirable because it cannot be readily used as part of the pouch collection volume, and it simply undesirably increases the size of the pouch 20.

  The present invention provides a surprising solution to these problems.

One aspect of the present invention is an ostomy appliance,

  In the operable position, the adhesive wafer is superimposed around the entrance opening of the instrument and the conformable area of the adhesive wafer is covered by the instrument on the non-body facing side. The access location provides access to the adaptable area from the non-body facing side.

  Such an arrangement can guide the alignment of the wafer and instrument relative to the operable position, making it easier for the elderly, clumsy, or visually impaired. At the same time, the range-of-motion coupling allows for relative displacement of the entire bonded wafer relative to the inlet opening and allows access to fit the bonded wafer to the size and / or shape of the user's fistula. To do. The range-of-motion connection may include articulating links that define a trajectory of range of motion limitation.

  This aspect of the present invention may be used with an integrated instrument to enhance access to an adhesive wafer while avoiding the problem of an adhesive wafer that is totally or partially stationary as in the prior art. . The ability to displace the entire bonded wafer relative to the entrance opening of the pouch may allow easier fitting of the wafer (by forming, cutting or shaping the fistula opening, or fisturing) By fitting and / or shaping a separate sealing member in the opening).

  Similarly, this aspect of the invention also significantly reduces the convenience of access to fit the wafer to the size and / or shape of the fistula or the instrument can be placed in an operable position relative to the body equipment. It may be used with a two-piece instrument to facilitate easier alignment of the components without compromising the ability to position the body fitting on the body prior to securing to the body. The range-of-motion restricting connector and the fixed connector may include a releasable connecting portion.

The second aspect of the present invention is:
(A) providing an ostomy appliance, the ostomy appliance comprising:
An instrument device having a pouch with an inlet opening for communicating with the fistula;
An adhesive wafer for placing on the body around the fistula, which fits around the fistula, a body-facing side to contact the user's skin, a non-body-facing side opposite the body-facing side An adhesive wafer including a conformable region that is conformable to

(C) moving the adhesive wafer to the operable position relative to the inlet opening;
(D) further comprising fixing the adhesive wafer in the operable position using the fixed connector.
Another aspect of the present invention provides:
A mooring connection for permanently attaching the bonded wafer to the instrument in a manner that permits relative displacement between the inlet opening of the pouch and substantially the entire bonded wafer;
An integrated instrument is provided that includes a fixed coupling for securing the adhesive wafer to the inlet opening when in the operable position.
The mooring connector is made of a flexible plastic film, and the fixed connector is an adhesive.

The tether connector defines a tether range of motion between the instrument and the adhesive wafer. The mooring range is

(Ii) an access location that provides access to the adaptable portion of the adhesive wafer from the non-body facing side.

  The mooring connection may be a range-of-motion connection as described above to provide alignment guidance, or the mooring connection may be a tether that does not define a specific guidance trajectory. In any case, the use of mooring fittings facilitates easier access to the adhesive wafer of the integral instrument while avoiding the problem of a totally or partially stationary adhesive wafer as in the prior art. To do. The ability to displace the entire bonded wafer relative to the pouch inlet opening may allow easier fitting of the adaptable part (by forming, cutting or shaping the fistula opening). Or by fitting and / or shaping a separate sealing member at the fistula opening). The mooring connection also makes it possible to avoid the above-mentioned potential sealing problems in the discontinuity where both the stationary and movable areas directly contact the inlet opening.

  The mooring connection can also allow an adhesive wafer to be used that extends across or beyond the periphery of the pouch when in an operable position around the fistula opening. Such a shape allows the mooring connector to be positioned in an alternate position within the pouch profile, such that the peripheral welding and stamping operations can be performed around the pouch profile, or Since it can be displaced there, it can be easily realized.

  In any aspect of the invention, the ostomy appliance may be an ostomy pouch, or some other ostomy device, such as a fistula port or controlled drain device.

  As used herein, the term “permanently attached” (or similar phrase) separates parts without breakage or damage that prevents reattachment without additional equipment. It means that it can be installed very strongly so that it cannot.

  2-8, a first embodiment illustrates an integrated ostomy appliance 30 that includes an ostomy pouch 32 as an appliance device and an adhesive wafer 34 that is permanently attached to the ostomy pouch 32. The ostomy pouch 32 may be any of a colon ostomy pouch, a bladder ostomy pouch, and an ileal ostomy pouch.

  The ostomy pouch 32 generally includes a rear wall 36 and a front wall 38. The front and rear walls 36, 38 are generally made of a flexible plastic membrane that is impermeable to liquids and gases. Suitable membranes include, for example, one or more layers of ethylene vinyl acetate (EVA) and one or more layers of a gas barrier material such as poly (vinylidene chloride) (PVDC) or poly (vinylidene fluoride) (PVDF). Nolaminate. The walls 36 and 38 are welded together around the shared peripheral seam 40. The rear wall 36 includes a fistula or inlet opening 42 through which fistula effluent enters the pouch 32 in use. The pouch 32 further optionally includes a deodorizing filter and vents (not shown) for deodorizing and ventilating the intestinal gas. Additionally or alternatively, the pouch 32 optionally further includes a comfort panel (not shown) on the outer surface of one or both of the walls 36,38.

  The adhesive wafer 34 includes a skin compatible adhesive for use in attaching the device to the peristomal skin. The adhesive wafer 34 generally has a body-facing side 46 that faces and contacts the skin in use and a non-body-facing side 48 that faces away from it in use. The body facing side 46 may initially be protected by a release sheet 50, eg, a silicone sheet or a silicone coated sheet. The bonded wafer 34 allows the fistula opening 52 to be customized to match the size and shape of the fistula 60 (FIG. 6) of a person who has been formed and / or has undergone ostomy. It can be adapted. Various techniques are envisioned for performing such adaptations. In one form, the adhesive wafer 34 is of a moldable or moldable type in which at least a portion 34a of the adhesive is moldable or moldable by manual operation. The bonded wafer 34 may have a pre-formed starter fistula opening 52 that is moldable or shapeable at least around the inner peripheral region of the bonded wafer portion 34a. Alternatively, if the starter fist opening 52 is not provided, the adhesive may be of the type that allows the user to manually create and form a suitable opening 52 therein. Formability and / or shapeability allows a tight or close fit to be achieved around the stoma 60. The close fit (i) protects the peristomal skin 62 of a person who has undergone ostomy from contact with excretion exiting the fistula 60, and (ii) otherwise increases the wear life of the device 30. It is highly desirable to form a seal that prevents fistula discharges from contaminating the adhesive surface on the body facing side 46, which may reduce. For example, the adhesive wafer 34 may be of the type described in the aforementioned US Pat. No. 6,840,924. Such an adhesive wafer 34 enables modeling while maintaining a sheet-like shape. Adhesive wafer 34 comprises a laminate structure comprising (i) multiple layers of adhesive and / or (ii) at least one layer of adhesive reinforced by at least one layer of plastic film. The fistula opening 52 in the adhesive wafer 34 expands to a customized shape and / or size by bending and rolling the adhesive wafer 34 over itself around the fistula opening 52, as illustrated in FIG. be able to. Typically, the adhesive wafer 34 is rolled onto the non-body facing side 48 of the adhesive wafer 34 and this operation is most easily and accurately performed from the non-body facing side 48. Alternatively, the adhesive may be of a flowable or extrudable mass type (not shown). Again, such adaptation is most easily and accurately performed with access to at least the non-body facing side 48 (preferably both sides 46, 48).

  In an alternative form, the fistula opening 52 may be adapted or customized by fitting a separate sealing member (not shown) that seals the fistula opening 52 interior. Such a sealing member is also best fitted to the non-body facing side 48 of the adhesive wafer 34 so as not to interfere with the adhesive interface between the body on the body facing side 46 and the adhesive wafer 34.

This embodiment initially facilitates access to the non-body facing side 48 of the adhesive wafer 34 because the adhesive wafer 34 is not permanently attached around the entrance opening 42. Instead, the instrument 30 further
The adhesive wafer 34 is moored in a pouch 32 in a manner that allows relative displacement between (a) (i) substantially the entire inlet opening 42 of the pouch 32 and (ii) substantially the entire adhesive wafer 34. Mooring connection 54, permanently attached to
(B) Optionally includes one or both of fixed couplings 56 for securing the adhesive wafer 34 to the pouch 32 in an operable position around the inlet opening 42.

Prior to initial use, the mooring connector 54 allows relative displacement between the adhesive wafer 34 and the pouch 32 over the mooring range of motion. The mooring range is
(I) a superimposed operable position where the adhesive wafer 34 is superimposed around the entrance opening 42 and the conformable portion 34a of the adhesive wafer 34 is covered by the pouch 32 on the non-body facing side 48;
(Ii) includes an access location that provides access from the non-body facing side 48 to the adaptable portion 34a of the adhesive wafer 34;

  Such an arrangement provides one pouch 32 and one against the other to provide convenient access to the adhesive wafer 34 from the non-body contact side 48 without substantial interference by the pouch 32. Allows easy handling of the bonded wafer 34. Preferably, the user has access from both sides 46, 48. Thus, the user can easily form and / or shape and / or dimension the fistula opening 52 without requiring significant dexterity to operate the instrument 30.

  In the illustrated form, the mooring connection 54 is preferably implemented in the form of a range-of-motion connection that induces relative displacement along a defined movement path or path. Such a range-of-motion connection can guide the range of motion between the adhesive wafer 34 and / or the pouch 32 to an operable position in at least one sizing or degree of freedom. This may, for example, allow easier alignment of the adhesive wafer 34 with the pouch 32 than a conventional two-piece instrument where the adhesive wafer 34 is generally free to move relative to the instrument prior to fixation. it can.

  The user can determine how to best fit the instrument 30 to the body. In one technique, the user fits the adhesive wafer 34 substantially completely before fitting the instrument 30 to the body. Having the adapted adhesive wafer 34 in the non-overlapping position allows the user to move the adhesive wafer 34 to its operable position (FIGS. 4 and 5) prior to fitting the instrument 30 to the body. The bonded wafer 34 is fixed in place by a fixed connector 56 after the instrument 30 is fitted to the body in the form of a conventional integrated instrument.

  In another technique (illustrated in FIG. 6), which may be preferred by many users, the adhesive wafer 34 is removed from the body before the adhesive wafer 34 is secured in its operable position relative to the pouch 32. 58. This technique allows the user to adapt or further adapt the fistula opening 52 in situ around the fistula 60 while accessing the adhesive wafer 34 from the non-body facing side 48. The flexibility of the pouch 32 may allow the pouch 32 to be easily folded from the entire adhesive wafer 34 to expose the non-body contact side of the adhesive wafer 34 for the user. When the user is satisfied with the custom fit of the fistula opening 52 to the user's fistula 60, the user then moves the pouch 32 to move the inlet opening 42 relative to the adhesive wafer 34 to an operable position. Or expand (indicated by arrow 64). If a range of motion connector is implemented, the connector guides the range of motion to the operable position and greatly assists the user. When in the operable position, the pouch 32 is then fixed relative to the adhesive wafer 34 by a fixed connector 56.

  Various methods are envisioned for implementing (i) the mooring connection 54 and (ii) the fixed coupling 56.

  The mooring connector 54 may be at least one of flexible, bendable, rotatable, pivotable, twistable, and / or telescopic to allow relative displacement. In an alternative form, the mooring connection 54 may be substantially rigid and the relative displacement is provided by the flexibility of the pouch 32 itself.

  In the form illustrated in FIGS. 1-7, the mooring connector 54 includes a bendable and / or hinged connector. The mooring connector 54 includes a first attachment portion 66, a second attachment portion 68, and a bendable or hinged joint 70 between the two portions 66, 68. The mooring connector 54 may be made of a single piece of material and the bendable joint 70 may be an integral hinge, such as a fold or bendable portion, or a living hinge, or weakened, thinned, perforated, and It may also be implemented as an area that is one of the divided areas. For example, the mooring connector 54 may be made of a single piece of plastic membrane. The membrane is flexible and may optionally be weakened so as to define a connector 70 in which the membrane is facilitated to bend.

  Alternatively, referring to FIG. 7, the two portions 66, 68 may be different members joined by a hinge piece 70a or 70b. The hinge part 70a may be made of a flexible material such as a cloth or a flexible film, for example. Alternatively, the hinge part 70b may be a hinge mechanism, possibly including a rotational pivot.

  In the form illustrated in FIGS. 1-7, the connector 70 generally extends parallel to the major plane of the adhesive wafer 34 and / or pouch 32 (when straight) and allows relative displacement about the axis. . One advantage of this arrangement is that when the adhesive wafer 34 is displaced relative to the entrance opening 42, the non-body facing side 48 of the adhesive wafer 34 is automatically exposed and presented for the user. That is. For example, for a relative displacement of about 180 degrees (FIGS. 2, 3, 6 and 7), the non-body contact side 48 is presented on the posterior pouch wall 36 opposite the user. Such a shape provides very convenient access to the non-body contact side 48 of the adhesive wafer 34 even though the adhesive wafer 34 is permanently attached to the pouch 32 as an integral device. Thus, the user can easily access the adhesive wafer 34 from at least the non-body contact side 48 to allow the most accurate and universal fit of the fistula opening 52.

  The first attachment portion 66 is configured to be permanently attached to the pouch 32, for example, by welding or by a strong adhesive. The first attachment portion 66 may be attached to any of the pouch walls 36, 38 and / or at the seam 40. In the illustrated form, the first attachment portion 66 is attached to the rear wall 36 adjacent to the inlet opening 42. The first attachment portion 66 includes a generally hollow configuration (preferably in the form of a closed loop) that extends at least partially (and preferably completely) around the inlet opening 42. The first attachment portion 66 may function to reinforce the pouch wall material around the inlet opening 42 and provide a good surface for the fixed connector 56 to prevent wrinkling or stretching. .

  The second attachment portion 68 is permanently attached to the adhesive wafer 34, for example, by welding or by a strong adhesive action (eg, between the adhesive of the adhesive wafer 34 and the second attachment portion 68). Configured as follows. In the illustrated form, the second attachment portion 68 is attached to the adhesive wafer 34 on the non-body contact side 48 in the peripheral region 34b that surrounds the inner peripheral region 34a. The second attachment portion 68 may have any desired form. As illustrated, the second attachment portion 68 has a generally hollow form (preferably, preferably) extending at least partially (and preferably entirely) around the fistula opening 52 and / or the adaptable region 34a. Closed loop form).

  The mooring connector 54 may be similar to an 8-shaped configuration, including two closed loop configurations that are arranged side by side (directly adjacent or slightly separated) and connected by a connector 70.

  The first and second attachment portions 66, 68 are typically approximately the same size, ie, the same size inner diameter and so as to fit substantially back to back in the operable position. / Or having an outer diameter. Each attachment portion may have a respective tab 66a, 66b that is positioned such that the tabs 66a, 66b generally coincide with the operable position and are fully overlapped together. Tabs 66a, 66b allow easy manipulation of mooring connection 54.

  With reference to FIGS. 8 and 9, an alternative connector 70 may be configured such that the pouch 32 and the adhesive wafer are in a plane that is generally parallel to the plane of the pouch 32 (when straight) and / or substantially parallel to the major plane of the adhesive wafer 34. A pivot axis 72 is included that allows pivotable relative motion between the pivot axis 34 and. The pivot 72 may include a pin, lug, or rivet that is received within an opening in the overlapping tabs 66b, 68b of the first and second attachment portions 66,68. In the illustrated form, the first and second attachment portions 66, 68 are each in a closed loop shape. The pivot 72 enables the first and second mounting portions 66, 68 to move from a generally concentric superimposed relationship (corresponding to the operable position) to a generally non-concentric non-superimposed relationship, and Apart from 42, it allows access to the bonded wafer 34. As can be seen in FIG. 9, there is no reversal of the positions of the body facing side 46 and the non-body facing side 48 when the anchoring coupler is rotated. Nevertheless, the flexibility of the plastic membrane forming the first and second attachment portions 66, 68 is such that when the wafer 34 is rotated away from the operable position, the non-body facing side 48 is Allows easy access.

  FIG. 10 shows a modification of the second embodiment that provides an additional indentation when the bonded wafer 34 is rotated to its operable position. The adhesive wafer 34 has an outer diameter that is slightly smaller than the inner diameter of the fixed connector adhesive 84 loaded on the first mounting portion 66, and the adhesive wafer 34 is open to the fixed connector adhesive 84. Within, it is sized to allow at least partial nesting. This nesting provides the user with additional tactile information that the bonded wafer 34 is accurately aligned with the operable position. The same technique of nested mating may also be used with other embodiments described herein.

  Referring to FIGS. 11-14, an alternative mooring connector 54 is shown in FIGS. 1-7 except that the first attachment portion 66 for attachment to the pouch 32 has the form of a tab instead of a closed loop shape. It has the same folding action as that of. Two different structures of the tab are estimated. 11 and 12, the connector 70 is disposed on the portion of the tab 76 that faces away from the inlet opening. In the same manner as in FIGS. 1-7, the connector 70 is deployed in the access position and folds over itself when the inlet opening 42 and the adhesive wafer 34 are in an operable overlapping position. The bonder 70 deploys when the adhesive wafer 34 is placed away from the inlet opening 42.

  In the alternative arrangement of FIGS. 13 and 14, the connector 70 is generally disposed between the tab 76 and the inlet opening 42. In the access position, the connector 70 is folded. In the operable overlapping position of the inlet opening 42 and the adhesive wafer 34, the connector 70 is generally deployed.

  When the tab 76 is used, an alternative reinforcing member 80 may be provided surrounding the inlet opening 42. The reinforcing member 80 may have a tab 80a to assist the operation of the pouch 32. The reinforcing member 80 is a material having a greater flexural modulus than the material of the pouch walls 36, 38 so as to protect the pouch walls 36, 38 from wrinkles and promote a good seal around the inlet opening 42. is made of.

  Fixed connector 56 may be an adhesive or a mechanical connector. The fixed coupler 56 may be of a permanent type that is not intended to be separated (or refastened) after it is first fastened together. Alternatively, the fixed coupler 56 may be of a separable and refastenable type. This allows the pouch 32 away from the adhesive wafer 34 to allow a caregiver or nurse to inspect, clean, or apply the medicine to the fistula 60 while the adhesive wafer 34 is in situ on the body. Allows opening.

  An adhesive connector is currently preferred for mounting the fixed connector 56. Adhesive connectors typically provide a lower profile height than mechanical connectors. The adhesive connector may use a skin-friendly adhesive on the adhesive wafer 34 or may use a different adhesive. The adhesive connector may include self-adhesive films that stick together without sticking.

  In one form (as illustrated in all embodiments), the fixed coupling 56 is different from the wafer 34 by at least one of the first and second attachment portions 66, 68 of the mooring connection 54. It includes an adhesive layer 84 to be loaded. Both attachment portions 66, 68 may carry such adhesive, or one of the attachment portions 66, 68 may be a non-adhesive landing area. In the form illustrated in FIGS. 2-14, the first attachment portion 66 is loaded with adhesive 84 and the landing surface is provided by the second attachment portion 68. However, the position of the adhesive may be reversed if necessary. The adhesive layer 84 may initially be protected by silicone or a silicone-coated sheet 86. Release sheet 86 may have a release tab 88 that is typically angularly spaced away from tabs 66a, 80a to avoid confusion. The adhesive 84 may be of the same type and / or thickness suitable for use in adhesively joining two-part ostomy appliances, thus reducing the thickness or profile height of the appliance 30. Does not increase significantly.

FIGS. 15 and 16 illustrate a further example of a mooring connector 54 loaded by both first and second attachment portions 66, 68 on their respective surfaces that face each other when in an operable position.

These drawings also include an adhesive wafer comprising adhesive layers 34c, 34e separated by a flexible sheet 34d that provides similar moldable properties as described in the aforementioned US Pat. No. 6,840,924. 34 exemplary structures are illustrated.
In another form, the fixed coupler 56 includes a portion of the adhesive surface of the adhesive wafer 34 on the non-body facing side 48.

  In the above embodiment, the adhesive wafer 34 is sized and positioned so that it is generally located within the welded periphery 40 of the pouch 32. However, a further feature of the present invention is that when the adhesive wafer 34 is in an operable position, for example, as illustrated in FIG. 17, the adhesive wafer 34 extends over all of the peripheral welds 40 of the pouch 32 or that It is possible to provide an integrated device 30 that extends even further. The mooring connector 54 allows such an adhesive wafer 34 to be placed during manufacture in a position where the adhesive wafer 34 does not have a place where the peripheral weld 40 is made therein. ,there is a possibility. This allows conventional welding equipment to approach the position of the peripheral weld 40 without being obstructed by the wafer 34. This modification may be used in combination with any of the mooring and / or fixed couplings described herein.

  The same principles described above may also be applied to two-piece devices and / or to one-piece devices provided in separate or “kit” form. In the case of a two-piece device, the fixed connector 56 may be a conventional two-piece connector, either of the adhesive or mechanical interface / interlock type. The first attachment portion 66 of the mooring connector 54 is preferably securable, eg, releasable, to the pouch prior to aligning and securing the two-piece instrument components.

  The above principles will now be illustrated by further detailed examples.
