The mounting wafer (14) has a landing zone film formed of releasable plastic, and the pouch (12) has a face plate (50) with a resealable adhesive that secures to the landing zone of the mounting wafer (14). The landing zone of the mounting wafer (14) includes one portion that is immovable with respect to the body surface that the mouting wafer (14) is secured to, and another portion that is deflectable away from the body surface. The deflectable portion of the landing zone, also referred to as the floating landing zone, is sized for gripping between the fingers during pouch separation from the mounting wafer (14). Gripping of the floating landing zone during pouch separation helps isolate the pouch separation force from the abdominal area underlying the mounting wafer (14).

Description

REPOSITIONING BAG WITH FLOATING SETTING AREA Field of the Invention The present invention is directed to ostomy systems wherein a bag and a wafer or mounting plate are adhesively coupled, and more particularly to an ostomy system wherein the forces of pulling or detachment of the bag exerted on a wafer or plate Assembly during the separation of the wafer pouch or mounting plate, can be substantially isolated from the underlying abdominal area of the wafer or mounting plate.

Background of the Invention An adhesively coupled ostomy system such as that shown in U.S. patent application. Serial No. 08 / 609,318 includes a bag with a fastening plate that is adhesively secured to a wafer or side mounting plate of the body. The ostomy system, because of the removable and resealable adhesive coupling arrangement, allows the repositioning of the bag in relation to the disc REF .: 120063 side assembly of the body. Accordingly, once a bag has been adhesively secured to a wafer or mounting plate, the bag can be removed and re-insured when desired to obtain optimum positioning of the bag on the wafer or mounting plate. To facilitate the repositioning or removal of the bag after it has been adhesively secured to a wafer or side mounting plate of the body, a finger-clamped tab is provided on the bag holding plate for clamping between the body. thumb and index finger for example. During the removal of the bag, when the bag is held in the lug of the holding plate, the pulling or detaching force is directed through the lug and the bag holding plate whereby any stretching of the bag is minimized. the envelope of the bag. Accordingly, the bag can be disengaged and can be repositioned on the wafer or mounting plate for optimal fit. However, the pulling force of the bag is generally resisted on the wafer or mounting plate and felt by the user in the underlying abdominal area. Since the underlying abdominal area is often sensitive to stress or strain, the pulling or pulling force of the bag from the mounting plate can be annoying to the user. Accordingly, it is desirable to provide an adhesively coupled ostomy system that enables the pulling force of the bag from the wafer or mounting plate to be isolated on the wafer or mounting plate to minimize stress or strain on the underlying abdominal area of the wafer. the wafer or mounting plate.

DETAILED DESCRIPTION OF THE INVENTION An ostomy system incorporating an embodiment of the invention is generally indicated by reference numeral 10. Referring to Figure 1, the ostomy system 10 includes a pouch 12 and a wafer or mounting plate 14 lateral to the body, shown in FIG. separate position. The wafer or side mounting plate 14 of the body includes an opening 16 for a stoma 120 and is adhesively secured to an abdominal surface 100 in alignment with the stoma 120. The ostomy bag 12, which is expandable, is formed of a wrapping known 18 of flexible thermoplastic material made in accordance with the techniques known in the art of construction of the ostomy pouch. The material of the bag is impermeable to gas and water. The envelope 18 of the bag includes a front wall 20 (Figure 2) facing the abdominal surface 100 and a back wall 22 (Figure 1) facing the abdominal surface 100. Referring to Figure 6, the back wall 22 of the bag 12 includes an inner layer 24 of the same material as the front wall 2'0, and an outer layer 26 of perforated polyethylene fluff. The outer layer 26 provides a comfortable surface contact between the bag 12 and the abdominal surface 100. As seen in Figure 6, both of the layers 24 and 26 respectively include an inlet opening 30 for debris, aligned. The front and rear walls 20 and 22 of the bag 12 are joined together by a peripheral thermowelding 34 (Figures 1 and 6).

The envelope 18 of the bag further includes an upper portion 36 (Figure 1) with rounded corners, the opposite side portions 38 and 40 that are substantially parallel, and a curved lower portion 42 that fuses or joins in opposite side portions 38. and 40. The envelope 18 of the bag thus defines a chamber 46 for collection of waste (Figure 6) accessible through the inlet opening 30 for waste from the rear wall 22. The inlet opening 30 for waste it has a diameter of approximately 4.44 cm (1 3/4 inches) and is located closer to the upper portion 36 of the envelope of the bag than the lower portion 42. The bag 12 further includes a generally annular adhesive holding plate 50 which limits or borders the entry opening 30 for waste. The internal diameter of the facing or facing plate 50 is aligned with the inlet opening 30 for the debris of the bag 12 and is substantially of the same length. For purposes of simplicity, the internal diameter of the facing or clamping plate 50 is also referred to by the reference number 30. The facing or clamping plate 50 is fixed to the rear wall 22 of the bag 12 by an annular or adhesion thermoshrinking. The facing or clamping plate 50 includes a manipulatable ear 54 approximately 2.54 cm (1 inch) wide (Figure 1) and extending approximately 1.27 cm (1/2 inch) beyond an outer diametral periphery 56 of the plate facing or clamping 50 at an angle of approximately 50 ° to 60 ° from the vertical. The surface portion of the facing or clamping plate 50 between the internal and external diameters 30 and 56 is referred to as the adhesion area of. the opposing or holding plate. The facing or clamping plate 50 is preferably formed of a resealable foam tape 60, such as of the type manufactured by the 3M Company of Minneapolis, Minnesota and designated as Medical Foam Tape for Coating No. 9776. The resealable foam tape 60 includes a foam backing of alveolar polyethylene or closed cells approximately 0.08 mm thick with a hypoallergenic pressure-sensitive acrylate adhesive 62 (Figure 6) that is in the adhesion area of the facing or fastening plate and a paper releasable silicone (not shown) that normally covers the adhesive 62. The opposing or holding plate 50 has an internal diameter of approximately 4.44 cm (1 3/4 inches), and an outer diameter of approximately 8.57 cm (3 3/8) inches).

The portion 54 of the lug of the facing plate 50 includes a layer 66 of the film (Figure 1) laminated to the acrylic adhesive 62 of the lug 54. Preferably the layer 66 of the film is of a flexible polyvinyl chloride sheet material , plasticized, from about 0.0254 to 0.20 cm (0.010 to 0.080 inches) in thickness, with an outer surface that is non-adhesive to facilitate manipulation of the portion 54 of the lug and to reinforce the lug 54 when it is manually held between the fingers as shown in Figure 7. As clearly shown in Figure 6, a rear surface 68 of the portion 54 of the lug facing the back wall 22 of the bag 16 is non-adhesive and is not attached to the wall 22 of the bag to further ensure that the portion 54 of the lug is accessible for manual attachment and handling. The manipulation or clamping of the lug 54 makes it possible for the user to detach the facing or clamping plate 50 from the wafer bag or mounting plate 14 during the removal of the bag or separation from the bag as shown in Figure 7 During the removal of the facing or securing plate 50 from the bag from the wafer or side mounting plate 14 of the body, the detachment force is directed through the lug 54 and the area of the facing or holding plate, instead of the walls 20 and 22 of the bag 12. Referring to Figures 3-6 the wafer or side mounting plate 14 of the body is a laminate of generally circular and rectangular layers. The wafer or mounting plate 14 has a central opening 16 with a diameter of about 1.90 to 3.17 cm (3/4 to 1 inch). Referring to Figures 4 and 5, the wafer or side mounting plate 14 of the body includes an annular adhesive disk 70 for abdominal contact. The disc 70 is covered on one side with a removable layer 72 of silicone release paper and on the other side with a non-removable layer 74 of plastic film also referred to as the first layer of the film of the landing zone or settlement , preferably formed of a polyethylene film. The layers 72 and 74 are substantially identical in the internal and external diameter of the abdominal adhesive disk 70. The abdominal adhesive disk 70 is preferably formed of a hydrocolloid adhesive, from about 0.076 to 0.20 cm (0.030 to 0.080 inches) in thickness, such as of the type sold under the trademark Stomahesive® or Durahesive® by Bristol-Myers Squibb Company of New York, New York.

The wafer or side mounting plate 14 of the body further includes a generally rectangular woven collar 76 having an internal diameter 77. The woven collar 76 is preferably formed of a Fasson material having an adhesive coating 78 (FIG. 5) facing the first layer 74 of the film of the landing zone or settlement and a non-adhesive, perforated, smooth back surface 80. A silicone release collar 82 for the adhesive side 78 of the collar 76 has preformed cut lines 84 and 86 (Figure 5) defining opposed handling segments 88 and 90 and an intermediate section 92. For simplicity reference numbers 88, 90 and 92 are also used to define the corresponding underlying segments and adhesive sections on the surface 78 of the woven collar 76. Under this arrangement, an annular portion "t" (Figure 4) of the adhesive side 78 of the woven collar 76 is joins the layer 74 of the polyethylene film. Referring to Figures 4 and 5, a generally rectangular layer 102 of plastic film, also referred to as the second layer of the film of the landing or settling area, is attached to the first layer 74 of the film layer of the landing or settling area and the woven collar 76. The layer 102 is preferably formed of polyethylene and may be of the type manufactured by the 3M Company of Minneapolis, Minnesota under the designation Clear PE Release Film 3M MSX-1198. The second layer 102 of the landing zone film is approximately 0.030 cm (12 mils) thick, has an internal diameter 106 of approximately 3.81 cm (1? _ Inches) and a width across the faces approximately 9.52 cm (3% inches). An exposed landing or landing surface 104 is defined between the internal diameter 106 and the outer periphery of the layer 102. An easily visible, obscured edge 114 is provided on the layer 102 close to the internal diameter 106 and another edge or indication limit 116 easy to see, obscured, is provided on layer 102 proximate its outer periphery. The indication edges or boundaries 114 and 116 are preferably provided on the back side of the layer 102 but are shown in the drawings on the landing or seating surface 104 for clarity purposes. The second layer 102 of the landing zone film is attached at or near its internal diameter 106 to the film layer 74 by an annular ultrasonic weld 107 having an internal diameter of approximately 3.81 cm (1 inch) and an outer diameter of approximately 4.44 cm (1 H inches). The second layer 102 of the film of the landing zone is attached to the woven collar 76 at or near the internal diameter 77 of the woven collar 76 by an annular ultrasonic weld 108 having an inner diameter of approximately 5.39 cm (2 1 / 8 inches) and an outer diameter of approximately 6.03 cm (2 3/8 inches). Under this arrangement the second layer 102 of the film of the landing zone forms a radial extension of the landing or seating surface provided by the first layer 74 of the film of the landing zone. A portion of the second layer 102 of the landing zone film extending radially beyond the ultrasonic weld 108 is free of the securing to the woven collar 76 and is therefore referred to as the floating landing or landing zone. As shown more clearly in Figure 4, the wafer or mounting plate 14, as assembled for securing to the abdominal surface 100, includes the adhesive layer 70 sandwiched between the silicone release paper 72 and the first layer 74. of the film of the landing zone or settlement. The wafer or side mounting plate 14 of the body, assembled, also includes the woven collar 76 secured to a peripheral section of the first layer 74 of the film of the landing or settling zone. The woven collar 76 extends radially beyond the periphery of the first layer 74 of the film of the landing zone. The adhesive surface 92 of the woven collar 76 extending radially beyond the first layer 74 of the film of the landing zone is covered by the silicone release paper 82. The wafer or assembly plate 14 assembled includes in addition the second layer 102 of the film of the landing zone, secured to the first layer 74 of the film of the landing zone and the woven collar 76 as previously described. In the use of the ostomy system 10, the wafer or side mounting plate 14 of the body is first attached to the abdominal surface 100 before being coupled with the bag 12. Accordingly, the silicone release paper 72 is removed from the disc Abdominal adhesive 70 and intermediate section 92 of release paper 82 is removed from fabric collar 76. Release paper 82 temporarily remains at portions 88 and 90 of the opposite manipulation edge of fabric collar 76. Wafer or mounting plate 14 can then be handled by manipulating portions 88 and 90, to locate the opening 16 of the wafer or side mounting plate of the body in alignment with the stoma 120. The wafer or side mounting plate 14 of the body is secured to the abdominal surface 100 by the adhesive disc 70 and the exposed intermediate section 92 of the woven collar 76. The remaining release paper 82 in the handling sections 88 and 90 is then removed to expose the underlying adhesive and complete the securing of the tissue collar 76 to the abdominal surface 100. The portion of the woven collar 76 projecting beyond the periphery of the components 70 and 84 of the wafer or mounting plate are thus fixed to the abdominal surface 100 and thereby cover the peripheral edges of the abdominal adhesive disk 70 and the first layer 74 of the film of the landing zone or settlement. With the wafer or side mounting plate 14 secured to the abdominal surface 100, the bag 12 can then be secured to the wafer or side mounting plate 14 of the body. The silicone release panel (not shown) protecting the plate of the annular face 50 of the bag 12 is removed to expose the adhesive surface 62. The facing or holding plate 50 can be held in the portion 54 of the lug for facilitating the manipulation of the facing or clamping plate 50 against the first and second layers 74 and 102 of the film of the landing zone or seating of the wafer or side mounting plate 14 of the body. The portion 54 of the lug facilitates alignment of the entry opening 30 for debris from the bag, with the wafer or mounting plate 14 and stoma 120. In addition, the edges or limits of indication 114 and 116 are easy to see ( Figures 1, 3 and 5) on the inner and outer edges of the second film 102 of the landing or settlement zone facilitate such alignment. Once the bag 12 is secured by means of the holding plate 50 to the wafer or mounting plate 14, it may be desirable to adjust or reposition the bag 12 against the wafer or mounting plate 14. The portion 54 of the lug 58 the clamping plate 50 is accessible for manual clamping, as shown in Figure 8, to detach the annular clamping plate 50 from the first and second layers 74 and 102 of the film of the landing zone or settlement of the wafer or side mounting plate 14 of the body. The releasing qualities of the layers 74 and 102 of the film facilitate the removal of the holding plate 50 from the bag from the wafer or mounting plate 14. The pulling or detaching force of the bag on the holding plate 50 of the bag is exerted on the wafer or mounting plate 14 and the underlying abdominal area. Because the underlying abdominal area may be sensitive to the stress and effort of removal of the pocket, it is desirable to minimize such stress and tension in the abdominal area. The detachment force of the bag can be substantially isolated from the underlying abdominal area of the wafer or mounting plate 14 by holding the portion 110 of the floating or unattached landing zone or the second layer 102 of the landing or settlement zone. during the detachment process. Securing the wafer or mounting plate 14 in the floating landing zone 110 by the fingers 124 and 126 helps to provide a force on the wafer or mounting plate 14 that is the same and opposite to the peel force of the bag provided by the fingers 128 and 130 that hold the lug 54 of the holding plate. Accordingly, if the user begins to detect any tension or strain in the abdominal area during the detachment of the bag, the user may either increase or reduce the restraining force applied to the wafer or mounting plate 14. The user also it can manipulate the portion 110 of the landing zone or floating settlement to vary the direction of the restraining force, when necessary to counteract the detachment force of the bag. In this way, the underlying abdominal area is substantially isolated from the detachment force of the pocket. Consequently the tension and strain on the underlying abdominal area during the detachment of the bag can be substantially minimized. The re-securing of the annular clamping plate 50 to the first and second areas 74 and 102 of the landing area of the wafer or side mounting plate 14 of the body is then carried out in a manner similar to that previously described. The resealing qualities of the adhesive surface 62 facilitates the securing of the holding plate 50 to the wafer or mounting plate 14. Another mode of the ostomy system is generally indicated by the reference number 140 in Figures 10 and 11 The ostomy system 140 includes a bag 142 identical to the bag 12 and a wafer or mounting plate 144. The wafer or mounting plate 144 (Figures 8 and 9) includes the adhesive disc 70 sandwiched between the silicone release paper 72 and the first layer 74 of the film of the landing zone or settlement, the woven collar 76 adhered to the first layer 74 of the landing zone film, the silicone release collar 82 with a second layer 150 of the film of the landing or settling area attached to the woven collar 76, and a security film 152 attached to the first and second layers 74 and 150 of the film of the landing zone. The second layer 150 of the film of the landing zone or settlement is formed of the same material as the second layer 102 of the film of the landing or settling zone of the wafer or mounting plate 14 and is also of a generally rectangular shape with a width across the faces of approximately 9.52 cm by 9.52 cm (3 by 3 H inches). The second layer 150 of the landing zone film differs from the corresponding layer 102 of the wafer or mounting plate 14 because it has a thickness of approximately 0.045 cm (18 mils) and an internal diameter 156 that is aligned with, and is of the same magnitude as the internal diameter 77 of the woven collar 76.

The easy-to-see edges or indication limits 158 and 159 are provided respectively close to the internal diameter 156 and the outer periphery of the second layer 150 of the landing zone film for the same purpose as the edges or boundaries of the landing zone. indication 114 and 116 on the wafer or mounting plate 14. The second layer 150 of the film of the landing zone is attached at or near its internal diameter 156 to the layer 74 of the film by an annular ultrasonic weld 160 (Figure 9) having an internal diameter of approximately 5.39 cm (2 1/8 inches) and an outer diameter of approximately 6.03 cm (2 3/8 inches). Under this arrangement the second layer 150 of the film of the landing zone forms a radial extension of the landing surface provided by the first layer 74 of the film of the landing zone. A portion 162 of the second layer 150 of the landing zone film extending radially beyond the ultrasonic weld 160 is free of the securing to the woven collar 76 and therefore referred to as the floating landing or landing zone 162. .

The security film 152 is a ring of plastic material, preferably formed of the same material as the first layer 74 of the film of the landing zone. The security film 152 has a thickness of approximately 0.005 cm (2 mils) with an internal diameter of approximately 4.44 cm (1 H inches) and an outer diameter of approximately 6.03 cm (2 3/8 inches). Ultrasonic welds (not shown) provided at or near the internal and external diameters of the security film 152 are bonded to the security film 152 in the first and second layers 74 and 150 of the film of the landing or settlement zone. in such a way that the security film 152 covers the internal diametral edges 77 and 156 of the woven collar 76 and the second layer 150 of the film of the landing zone. The security film 152 thus provides a temporary landing or settling surface between the first and second layers 74 and 150 of the film of the landing zone. During the use of the ostomy system 140, the wafer or side mounting plate 144 of the body is attached to the abdominal surface 100 and the bag 12 is attached to the wafer or mounting plate 144 in a manner similar to that previously described for the ostomy system 110. Referring to Figure 10, the adhesive surface 62 of the holding plate 50 of the bag makes contact with the first and second layers 74 and 150 of the film of the landing or settling area and the safety film 152, which provides a releasable surface for the resealable adhesive 62 of the holding plate 50 of the bag. Detachment or removal of the holding plate 50 from the bag from the wafer or mounting plate 144 is effected in a manner similar to that described for the ostomy system 10. Accordingly the holding plate 50 is held in the portion 54 of the lug and the wafer or mounting plate 144 is held in the landing area or float 162 as shown in Figure 11. In this way, and as described with respect to the ostomy system 10, the fixture of the wafer or mounting plate 144 in the landing area or float 162 by the fingers 124 and 126 helps to provide a restraining force on the wafer or mounting plate 144 that is equal and opposite to the peel force of the bag provided by the fingers 128 and 130 on the lug 54 of the holding plate.

Some advantages of the present invention evident from the foregoing description include a resilient ostomy system, of reduced profile, with a wafer or mounting plate having an area of floating settlement. An additional advantage is a manipulable lug portion of the bag holding plate and a manipulable portion of the wafer or side mounting plate of the body are manually clamped during the removal of the bag to help isolate the release force of the bag. pouch of the underlying abdominal area of the wafer or mounting plate. An additional advantage is the provision of boundaries or indication edges on the wafer or mounting plate to facilitate alignment of the bag holding plate on the wafer or mounting plate. In view of the above, it will be noted that various objects of the invention are achieved and other advantageous results achieved. Although several changes can be made to the above constructions and methods without departing from the scope of the invention, it is intended that all of the material contained in the above description or shown in the appended drawings will be construed as illustrative and not in a limiting sense .
