Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an ostomy appliance.
nce), a pad for the instrument, a mounting means for the instrument, and a parts assembly set for assembling the instrument.

PRIOR ART AND PROBLEMS TO BE SOLVED In a successful known system, described and illustrated in British Patent No. 1,571,657, an ostomy bag is attached to a skin-compatible loose medicated adhesive pad by a peelable coupling. However, patients with colostomy (OS)
tomaLe), it is desirable to provide a lightweight and simple adhesive attachment system.

Structure and Effects of the Invention In accordance with the present invention, there is provided a body-mountable pad of skin-compatible adhesive material having a stoma opening, and the ability to apply a new area of adhesive each time a clean colostomy bag installation is desired. The exposure provides an ostomy device comprising means by which a plurality of ostomy bags can be attached to the pad in sequence.

Further, according to an example of the present invention, there is provided a bag for receiving excrement to be discharged, a stoma opening in one wall of the layer, and a bag surrounding the stoma opening to protect the wearer's body when wearing the device. a flange with a flat side adapted to face toward the patient, a medicinal grade adhesive pad, and a plurality of double-sided adhesives carried on the pad and each having a peripheral protrusion separated by a peelable cover ring. A colostomy device consisting of a sex ring is provided.

The double-sided adhesive ring is intended for continuous use in attaching the bag via its flange to several pads of medicated edge adhesive material;
The above-mentioned pad is attached to the skin of the wearer (both male and female) in areas surrounding the ostium.

The reason for having multiple adhesive layers separated by peelable cover rings is so that one layer of the outer cover can be torn to expose a new double-sided adhesive ring. Thus, each time the bag is emptied or replaced, the bag can be securely reattached to the medicinal grade adhesive pad without the need for frequent removal of the pad. This is of considerable advantage in that the operation of removing and replacing such pads can be somewhat difficult and sometimes painful.

Such a device can be used with a 4- or 5-day bag by providing a corresponding number of double-sided adhesive rings. Each of the cover layers may have a radially projecting finger tab, which serves two purposes, firstly being able to convey a number or an indication (e.g. ``Monday''). Second, the cover layer can be easily peeled off to expose the underlying double-sided adhesive layer, so that the flat side of the bag flange can be brought into mutually facing contact with the exposed adhesive side. .

According to a preferred embodiment of the invention, the ostomy bag is attached to the body-attachable pad by a series of continuous peelable adhesive members each having a gripping tab. A soft microporous layer (film) or tape may be used to assist in attaching the pad to the wearer's skin. - In the example, these tabs are such that peeling of the first tab exposes the second tab and
The arrangement is such that the second tab is inaccessible to the user until the tab is peeled off. In other examples, the tabs extend radially and are angularly spaced from the tabs of adjacent adhesive members.

Alternatively, the double-sided adhesive layer may be replaced with a peelable cover layer (and the cover layers may be shaped and arranged so that they can be peeled off sequentially, i.e. each cover layer has a gripping tab). The pouches are arranged so that peeling off one tab exposes the lower tab.The pouches are then arranged so that peeling off one tab exposes the lower tab.To attach the clean pouch to a pad of skin-compatible material that is adhered to the peristomal area. Peel off each cover layer if desired to expose new areas of adhesive.

According to another preferred embodiment of the invention, there is provided a system attachable pad carrying a flange, the flange having a stack of continuous peelable adhesive members adhesively secured thereto for attaching a colostomy bag; A system-mountable pad is provided in which the flange and the pad are connected by a flexible web that allows limited relative movement in a substantially vertical direction to the pad therebetween. By using such an assembly, colostomy patients can have a post-flange (
that is, between the flange and the body) and can absorb the pressure applied to secure the bag to the exposed portion of the plaster stack.

According to yet another example of the invention, an assembled set of parts for making an ostomy device includes a side-applyable opening pad of skin-compatible material and a plurality of ostomy bags, the layers of which Each is fitted with a single layer of peelable cover, the removal of which exposes an annular area of adhesive surrounding the stoma opening in the bag wall, which area is padded with each layer in turn during use. Arranged so that they can be fixed with adhesive.

Still further in accordance with a preferred embodiment of the invention, the body-mountable skin-compatible pad is attached to a disc of plastic material (e.g. vacuum-formable material) having a raised rim, with a narrow closed loop line within said rim; This allows the user to manually remove the central area of the disc. The opening thus formed serves as a stoma opening.

During use, the user cuts or punches holes in the pad of skin-compatible material for the stoma, removes the core of the plastic material, and applies the member to the body, allowing the internal edges of the pad to approximate the stoma. Defines the surrounding position and forms both a protective pad and a seal. The skin-compatible material covers the exposed inner edge of the disc and prevents pain or irritation caused to the stoma by the inner edge of the disc.

Also in accordance with the present invention, an adhesive bandage for use in attaching a colostomy bag to a body-attached member has a layer of adhesive protective cover, the layer of cover being capable of tearing its continuous separation area in sequence. It is configured to allow new adhesive to be exposed for attachment of a new colostomy bag.

Partially enlarged views, Figures 22 and 23 show an example of the present invention, which wraps around the stoma opening (acts as a wiper on the bag wall and attaches to the peripheral rib of the body-mountable flange). 24 and 25, respectively, show the attachment washer or flange of the layer, which is very suitable for use as a peel-off bag for the colostomy bag, and FIG. An enlarged view of a portion of FIG. 25 and FIGS. 27 and 28 are front views and vertical axial cross-sectional views, respectively, of the colostomy device and bag, showing a stack of releasable adhesives. Figure 3 shows the tapered rim of the member and the peripheral rib of the body flange, in which like parts are designated with the same reference numerals in such figures.

Referring first to FIGS. 1 and 2, the illustrated ostomy device includes a medicated grade adhesive pad 10 and an ostomy bag 12. As shown in FIGS. The colostomy bag 12 has a stoma opening 14 surrounded by a flange of, for example, synthetic plastic material, said flange being adapted to face towards the wearer's body during use of the device. It has an annular flat surface 16. The medicinal grade adhesive pad 10 also has a fixed flange 2.0, which may optionally have an internal peripheral rib 22. The flange 20 has an outwardly facing flat annular surface 24 adapted to receive a stacked double-sided adhesive ring 32 with an annular cover layer 34 inserted therebetween. Pharmaceutical grade adhesive pad 10 may be bonded to plastic film layer 26 in a conventional manner. In use, pad 10 and film 26 are cut to provide holes, indicated by dotted lines 28, through which the user's stoma can be passed.

Suitable medicinal grade adhesives include pressure sensitive adhesive formulations, such as one of the water-soluble or water-swellable hydrocolloids disclosed in Cheno, U.S. Pat. No. 3,339,506.
Consists of a homogeneous blend of seeds or more dispersed in a viscous elastomeric material (such as polyisobutylene). Such adhesive compositions may also optionally contain one or more of the cohesive reinforcing agents described in Cheno et al., U.S. Pat.
93080 can be included. Other commercially available pharmaceutical grade adhesives designed for colostomy patients are also suitable.

Double-sided adhesive rings are indicated at 32 and are illustrated here as five rings, for example. This is adequate for 5 days of colostomy equipment. For use, the fifth ring is directly adhesively attached, with one adhesive direction to face 24 and the other to peelable annular cover layer 34.

Identical covers N34 are located between adjacent double-sided adhesive rings, each of these cover layers having a radially projecting finger tab 36, as seen in FIG. Second, it is useful for supporting numbers or other visual indicia to assist the user in using the device.

The bag 12 is a bag having a waste discharge outlet 38 as shown in FIG.
or a closed bag that can be disposed of when full, as shown in FIG.

Note that although the term "ring" is used in this specification, it refers to one or more rings and does not have a strict geometrical meaning.In other words, there are several examples of double-sided rings used in the present invention. The double-sided adhesive layer does not have to be technically circular; any shape of the double-sided adhesive layer is suitable as long as it surrounds the stoma opening and can be peeled off from the adjacent layer to expose the adhesive area.

Referring now to FIG. 3, the aforementioned colostomy bag 12 and medicinal grade adhesive pad 1o are illustrated.

However, double-sided adhesive rings 32A, '32B, etc., with removable cover rings 34A to 34c inserted between them, are used from the one used first (closest to the bag) to the one used last (
The outer diameter gradually decreases toward the area closest to the pad. The reason for this is that when one of the peelable cover layers (eg, 34A) is removed, an area of new adhesive on the double-sided adhesive ring 32A is exposed, and when the next cover layer is removed, 34B.

This is to ensure that a new layer of adhesive on ring 32B is exposed. This minimizes damage (deterioration) to the outer edges of the adhesive ring.

Other features that differ compared to the specific examples in FIGS. 1 and 2 are:
The outer diameter of the adhesive layer is smaller than that of a single layer of cover (however,
The peeling tabs 36A to 36C, etc. are removed. Thus, the narrow outer rims of adjacent adhesive rings tend to poke each other and prevent any peeling from occurring except at the surface where the outermost peelable cover ring is removed.

4 and 5, a body-mountable member or pad 40 consists of a pad 42 of medicinal grade skin-compatible adhesive affixed to a disc 44 of plastic material.

The disc 44 has a raised rim 46 and a weakening closed loop line 48 (which may be circular) that defines an area within the rim 46 that can be easily removed by the user without the use of tools. Form.

A peelable protective layer 50 is applied to the back side of the pad 42. When the body-mountable pad 4o is applied to a patient's body, this layer 50 is peeled back to expose the adhesive side of the pad 42.

FIG. 5 shows the body-mountable pad member 40 in place on the body, with the patient's skin indicated at 52 and the ostium at 54. As can be seen, the inner helical edge 56 of the adhesive pad 42 is slightly skewed so that it contacts the periphery of the patient's stoma 54 and closely surrounds the stoma.

This provides a cushioning effect and the disc 44
The relatively sharp internal rim 58 of the pad 42 prevents the stoma from puncturing the patient's stoma, causing pain, and the good adhesive contact between the pad 42 and the stoma 54 provides a sealing effect, allowing liquid waste to be trapped in the stoma. Useful when applying adhesive in any of a variety of ways around the mouth.

In a preferred form of the invention, rim 46 is manufactured by vacuum forming. Many side-mountable parts also eliminate the need to separately mold a plastic disc with a rim component (
, can be easily manufactured.

Other embodiments of the invention are shown in FIGS. 6 and 7.

As seen in FIGS. 6 and 7, a pad 70 of skin-compatible medicated edge adhesive material carries a peelable rear cover layer 72 and supports a front cover sheet 74, as described above. The features of the pad 70 may be exposed in other ways.
A peelable annular paper or similar layer 78 covering the edge 76 of the pad 70 and extending beyond the pad 70 protects the adhesive on the rear surface (left hand side as shown in FIG. 6) of the protective layer 74. exist. As shown, pad 70 is flat disk-shaped and protective layer 74 is substantially prismatic. Pad 70 includes several plastic disks 82 carrying a central circular rim 84 forming a stoma opening 86 . Disc 82 supports a stacked pile annular adhesive attachment member (herein referred to as T) stacked on layer 74 .

Each bandage is constructed of tough paper or soft plastic film and has adhesive 85 and gripping tabs 92. The tab arrangement shown in FIG. 6 is such that the last bandage has the largest tab and the first RiJ bandage has a relatively small tab indicated at 94. The assembly is protected with a front cover annular layer 98 of release paper or other suitable material.

The colostomy bag can be applied to it by first peeling off one layer 98 of the cover to expose the adhesive in the annular area, and then applying the first adhesive tab 94 after the bag is full. It will be appreciated that the new adhesive on the exposed side of the next underlying plaster will be used to attach the next colostomy bag to the appliance.

8 and 9 show other variations of the invention,
The difference is that the tabs of the adhesive bandage 100 in this variant all have the same dimensions. As can be seen from Figures 8 and 9, adhesive 108 is provided between the bandage and the bandage except in the annular area, thus making it easy to separate one tab from the next. It is possible,
Additionally, the cover note 102 can be removed when the instrument is first used.

Yet another variation of the invention is shown in FIGS. 10 and 11. According to this advantageous variant, cover=Il 10
6 and bandage adhesive 108 each have an annular shape with an upwardly projecting tab, which tab 110 in the case of a single layer cover.
．． The case of each bandage is shown at 112. Each bandage has a tab that gradually increases in height from the bandage closest to the disk 82 to the bandage furthest from the disk 82. In addition, each tab has an elongated slot cut near its top 5 which allows the user's fingernail to be inserted into the slot, making it easier to separate one tab from the next. can. The slot in the cover layer is indicated at 114 and the opening in the front tab 112 is indicated at 116. 1st
1, other openings in tab 112 are not shown for simplicity.

With reference to the variations of the invention shown in Figures 6-11, it will be appreciated that any convenient number of separate bandages may be used. The five bandages are shown in Figure 6.

Although four bandages are shown in Figures 8 and 10, any number of bandages may be included in the device, such as one for each day of the week. Additionally, in certain cases, it may be preferable for the colostomy bag to be used in the illustrated device to have a relatively stiff plastic flange surrounding one stoma opening in the bag wall;
In other cases such rigid flanges may not be necessary (the bag wall could be adhesively secured directly to the exposed adhesive surface).

An embodiment of the pond of the present invention is also shown in FIG. 12, which shows, in schematic cross-section, a wearer's skin 120 featuring a body-mountable pad 122 of medicated loose adhesive material as described above. There is. The patient's stoma is indicated at 124 and projects through the appropriate hole in pad 122. A disk 126 carrying a circular rim 128 is attached to a pad 1 with a soft annular sort 130.
22. Sheet 130 may be fabric or a thin flexible plastic film.

The disk 126 carries a stack of circular bandages 132;
Each bandage has a tab 134.

A peelable protective front cover layer 136 protects the outermost bandage adhesive 138. A colostomy bag 140 having a stoma opening 142 surrounded by an annular shaped flat thin plate 144 cooperates with a body attachable device having a pad 122. In use, the protective cover layer 136 is peeled away to expose the adhesive layer 138 and the bags are lifted so that they are facing each other against the adhesive, and then the rim 128 is positioned just within the confines of the stoma opening 142. .

This holds the bag 140 securely in place on the disc 126 so that during its assembly, the user can place his or her fingers behind the disc 126 as desired and resist the pressure necessary to press the plate 144 against the adhesive 138. disc 1
It is necessary to support 26. A new bag can then be applied in a similar manner.

The illustrated adhesive cotton ML elbow 21o (FIGS. 13 and 14) consists of a base material 212 having a central hole 214 constituting an opening for a small hole.
(This includes, for example, the usual cloth base material found in common adhesive plasters).

An adhesive 216 is carried on the rear surface of the base material (body side), by which the bandage can be fixed to the body side attachable member 218 (not shown in FIG. 14).

The front side (bag side layer) carries an adhesive 220 covered with a peelable protective layer 222. The layer 222 has a circular section cut 2
24 into five annular regions 222a to 222e, and the length of the cut reaches approximately 3/4 of the thickness of the protective layer 222, for example.

These cuts can be made by punching or stamping. Alternatively, the cuts can be made completely through layer 222, or in several rows. A line with weak strength may be formed by providing a feed hole.

Other means will be envisaged by those skilled in the art.

Although circular holes 214 and circular cuts 224 are described, it will be appreciated that non-circular examples may employ oval shapes. However, a circular shape is preferred.

When using the assembly tool, use the medicated loose adhesive on the body side J4y,
An intervening member is attached to the pad 218.
230 (referred to as a chute member) is fixed to the cylindrical wall 230a of the
through hole 214. This hole is of sufficient size to accommodate the chute. Depending on its function, the chute
Guides the excrement flowing out from the small hole into the colostomy bag,
The chance that any waste material comes into contact with adhesive 216 or adhesive 220 is minimized.

If such contact were to occur, the security of attachment provided by the adhesive would be diminished. However, in cases where a very simple and inexpensive colostomy system is desired, chute 230 may be used. This can be omitted, and the bandage 21o is directly attached to the pad 218 with the adhesive 216.

In use, the inner ring 222a is peeled away to expose the annular adhesive 220 such that the bag wall with the stoma opening of the colostomy bag is in face-to-face contact with the exposed adhesive 220, and the bag wall /'' - The hole opening is substantially aligned with the hole 214.

To facilitate peeling off the rings 222a-222e, each ring may be provided with tabs or protrusions 232 that can be pinched between the fingers and thumb. These tabs may be numbered as shown in FIG. 13, if desired.

The colostomy bag used (not shown) may have a flat annular flange on its rear wall surrounding the stoma opening, or such flange may be omitted.
The back wall of the bag may be applied directly to the adhesive 220.

The intermediate member (chute) 230 may advantageously be made by vacuum forming a synthetic plastic film, and its flange 230b is preferably ultrasonically welded to the plastic film to form the outer boundary of the body-mountable pad 218. .

In an advantageous embodiment of the invention, adhesive 216 has a greater peel force than adhesive 220.
This may help maintain the attachment of the line side 210 to the pad 218 when force is applied to peel off one of the rings 222a-222e. Make it certain.

Figure 15 shows a medicated edge skin adhesive pad 24 that can be attached to the body side.
0 is shown, which is disk-shaped with a central hole 241;
That is, its shape is annular. A vacuum formed plastic rim 242 is attached to the pad 240. An adhesive bandage 244 according to the present invention is affixed directly to the front surface 246 of the pad 240 by any suitable method, such as an adhesive. Bandage 24
4 is a center hole 2 whose diameter is slightly larger than the outer diameter of the rim 242;
It has 48. Protective layer 250 can be removed from bandage 244 by hand. Layer 250 is separated into coaxial rings 250a-250d by cuts 252 (FIG. 16).

Each of these rings can be peeled separately from bandage 244. Although bandage 244 and body-attached pad 240 are shown as circular in shape, they can have other shapes.

Pad 218 (FIG. 13) or pad 240 (FIG. 15)
Figure) may be made from the medicated edge adhesive described above.

Advantageously shaped body-mountable pads are comprised of three layers: a skin-compatible medicated edge adhesive, a plastic film thereon, and a Fassone® adhesive covering the film.
on) consists of a wired plaster layer, the edge of which extends slightly beyond the outer edge of the adhesive and film. The adhesive and film usually have the same length. The purpose of the fasson fabric layer is to protect the edges of the adhesive so that these edges do not slide onto the wearer's clothing.

Referring now to FIG. 17, another embodiment of the inventive colostomy device of FIGS. 1 and 2 is shown in an exploded view. Such an ostomy device includes a soft microporous tape 1750 having a through opening 1751 that accommodates the rib 22. The diameter of the opening 1751 is larger than the diameter of the rib 22 (and smaller than the diameter of the flange 20).
includes. The outer surface 1754 of the microporous tape is a porous backing layer.

In FIG. 17, tape 1750 has a larger area than body-mountable pad 10' and is square or rectangular in shape. During use, the adhesive layer 1752 is pressed against the skin away from the stoma and the adhesive pad 10' assists in maintaining the ostomy device in position. Medicinal adhesive pad 10' and plastic film layer 26' are similar to pad 10 and ribs 26 of FIG. 1, except that they are circular in shape and generally have a smaller area.

The term "microporous" is used with respect to adhesive layer 1752, which means that layer 1752 appears to be continuous, but when observed under a microscope, channels and pores are randomly scattered. Due to its spongy nature. Layer 1752 is described in Copeland U.S. Patent No. 312,102.
The pad 10 may be made of acrylic as described in No. 1, or may have microporous properties obtained by different processing methods.
(see European patent application A110081/907). This microporous tape can also be used as the adhesive protective layer 74 in the embodiments shown in FIGS. 6-11.

The porous backing layer 1754 may be a woven or non-woven fabric (e.g., the rayon fabric described in Copeland, U.S. Pat. (polyurethane foam, polyethylene foam, etc.) or nonwoven materials made from commercially available polyester fibers, polypropylene fibers, nylon fibers, composite olefin fibers, or cellulose fibers.

Tape 1750 assists in attaching the colostomy bag to the user while being flexible and allowing the skin to breathe, providing a more comfortable attachment.

Tape F 50 may be secured to flange surface 24 of pad 10' not only by its own adhesive layer 1752 but also by an overlapping member 1758, such as a plastic film having an adhesive layer on each side. Division 175
8 has a through hole 1759, which is slightly larger than the diameter of the rib 22.

The outer diameter of member 1758 is larger than opening 1751 in tape 1750. Member 1758 overlaps both a portion of flange 20 adjacent rib 22 and a portion of side 1754 of tape 1750.

In FIG. 17, for example, five peelable adhesive members 1760 are shown, 1760A to 1760E. Each such member consists of a layer 1763 of tough paper or soft plastic film, with an adhesive layer 1762 and a gripping tab 1764. The arrangement of tabs is such that they are each angularly offset from the tab of an adjacent member 1760 about the coax of that member. The fifth peelable adhesive member 1760E, last in the order of use (ie, the one closest to member 1758), is applied directly to the outwardly facing adhesive side of member 1758. Member 1758 has one on each side thereof.
It will be recalled that there are two double-sided adhesive layers.

The non-adhesive side of each remaining member (those facing pad 10') is attached to the adhesive 11762 of the previous member facing surface 16 of bag 12.

The outermost peelable member 1760A used first is fitted with a suitable protective cover layer 1770 that protects the outer adhesive layer 1762 of the first member 1760A until use.

FIG. 18 is a front view of a member 1800 suitable for use as member 1760 of FIG.
Another example of G.764 is shown in detail. Member 1800 is preferably made from a transparent flexible plastic film and has an adhesive applied to one side (eg, outwardly facing member 1802). Furthermore, the member 1800 has the through hole 18
06 includes a circular gripping tab portion 1804. Tab 1
804 is thick enough to be easily pinched by the user's fingers, and opening 1806 facilitates the pinching.

19-21, the medicated loose adhesive pad 10 of FIG.
In particular, other designs of flange members are shown. This flange member 1920 has an internal peripheral rib 1922, similar to flange member 20 of FIG. To provide one lead-in when the user attaches the bag to one exposed adhesive side of the peelable adhesive member, the inner end, i.e. the end of the rib, is The ends are sloped inwardly, as seen at 1923 in FIG. 21, so that they extend toward the bag when the bag is applied and penetrate into the bag once secured. Accordingly, a tapered annular outer surface 1925 is provided which allows the wearer to direct the bag's stoma opening to the flange portion 1925.
920.

In another embodiment of the invention, seven peelable adhesive members are provided, which may be numbered, for example, from 1 to 7, and may be arranged in the manner shown in FIG. 22nd
and 23, the medicated adhesive pad is shown at 2310 and the flange thereon is shown at 2320, with an adhesive fabric layer 2321 disposed on the flange 2320 below the substrate of the stacked peelable adhesive members 2323. .

A flat annular plastic washer 2325 is secured to the colostomy bag wall 2327 (the other wall is shown as 2329). The flat annular washer 2325 may be a plastic material, and its structure has a central circular opening, the diameter of which is slightly larger than the outer diameter of the substantially cylindrical rib wall 2322. There is.

Thus, the bulge of the bag wall 2327 extends inwardly from the inner edge of the washer 2325 and acts against and adheres to the outer wall of the rib 2322 during use, thus keeping the outer wall clear of excrement. There is a tendency to

It will be appreciated that because the diameter of the stoma opening of washer 2325 is larger than the outside diameter of rib wall 2322, there is no need for careful and elaborate adjustment of relative position when applying the bag to the flange.

Instead of using a plain, flat annular washer 2325 as shown in FIG. 23, a colostomy bag washer of the shape shown in FIGS. 24 and 25 may be used. This washer may be made of, for example, ethylene-vinyl acetate polymer (
According to FIGS. 24-26, the layer surrounds the stoma opening of the colostomy bag 2510. Washer 251
2 has one annular flat curve 2514 adapted to accommodate one exposed adhesive (not shown) of the peelable adhesive member. The outer rim of the washer 2512 has a bead 25.

20 and forms part of washer 2512. This sealing strip 2520 performs a similar function on the inner surface 2331 (FIG. 23) of the bag wall 2327, and collects excrement from the cylindrical rib of the flange (e.g., flange 2320'). and help clean it up.

The same effect also applies to the cylindrical outer surface of the rib 1922 in FIG.

A flange 2720 is shown in FIGS. 27 and 28, which substantially corresponds to the design shown in FIGS.
Assembled with 724.

Bag 2722 is not shown in FIG. 27, and the arrangement of peelable adhesive members is similar in broad concept to that shown in FIG. 6.

Various proposals have been made in the past, for example, in British Patent Specification No. 1256866, it is known that a colostomy bag can be attached to a ring on the side of the body with adhesive, or a series of colostomy bags can be attached to a ring on the body side with adhesive. 11.
