Definitions

  • the current invention relates to an ostomy appliance comprising means for keeping the walls of the collecting bag separated, thereby reducing the risk of pancaking.
  • the current invention relates to means for reducing the risk of pancaking which also reduces the pull exerted on the collecting bag.
  • Ballooning and pancaking are two common issues relating to the use of ostomy appliances.
  • Ballooning occurs when there is a high pressure inside the collecting bag. This results in an inflated collecting bag which is uncomfortable, visibly disturbing and ultimately this may result in the ostomy appliance detaching from the user's skin because of the high pressure causing leakage.
  • pancaking occurs when there is a low pressure inside the collecting bag.
  • the low pressure causes the walls of the collecting bag to be sucked together preventing output from the stoma from falling correctly into the collecting bag. Instead, the output will build up at the inlet opening of the collecting bag providing a build up that prevents further output from exiting the stoma.
  • pancaking may cause the ostomy appliance to detach or even damage the stoma.
  • the following invention seeks to alleviate the issues caused by low pressure inside the collecting bag thereby avoiding pancaking.
  • the present invention relates to an ostomy appliance comprising a base plate having a proximal adhesive surface and a through-going hole extending in an axial direction through the base plate, the ostomy appliance further comprising a collecting bag arranged on the distal side of the base plate, the collecting bag comprising a proximal wall and a distal wall, where an opening is provided in the proximal wall for communication with the through-going hole, wherein the ostomy appliance further comprises a support member, wherein a first part of the support member is arranged and supported between the base plate and the collecting bag and a second part of the support member which has a distance from the first part of the support member along the axial direction of the ostomy appliance and engagement means are provided for engaging the second part of the support member to the distal wall of the collecting bag.
  • a support member which is able to keep the collecting bag open by keeping the walls of the collecting bag separated and thus reducing the risk of pancaking.
  • the support member is arranged and supported in an area between the base plate and the collecting bag. This prevents drag and pull from being formed in the collecting bag which may cause discomfort to the user or cause the upper part of the collecting bag to be pulled forward. This may cause closing of the bag or stop of the flow through the filter since, in many bag constructions, the filter is provided at the top part.
  • the walls of the collecting bag are not necessarily only formed of one material. They may be laminates of different material types or the walls may comprise different sheet materials placed next to each other but only attached to each other at the edges or at points by welds, adhesives or similar means.
  • the distal wall can for example be formed by a laminated sheet which is liquid and odour tight for preventing output and odour therefrom from penetrating the wall, while a second sheet of a non woven material is placed next to the laminated sheet.
  • the non woven sheet provides a comfortable feel against the skin and provides a moisture and vapour transporting material which keeps the skin dry.
  • the second part of the support member can be engaged to any of the parts of the distal wall.
  • the first part of the support member comprises coupling means and the support member further comprises a bridging element comprising at least a first and a second coupling area and wherein the coupling areas are separated by an intermediate section forming the second part of the support member.
  • the intermediate section extends along the distal surface of the distal wall of the collecting bag.
  • the engagement means can be provided as a sleeve on the distal wall forming a channel which is sized to receive at least part of the intermediate section of the bridging element.
  • the engagement means are provided as cooperating velcro elements provided on the distal wall and the intermediate section.
  • the engagement means can be provided as an adhesive provided on either the distal wall, the intermediate section or both.
  • ostomy appliances On many ostomy appliances known in the art, belt ears are provided for allowing the user to attach a belt to the base plate in order to provide added security from detachment. However, in many cases, these belt ears, which are often in the shape of looped rings, are not used.
  • at least a first and a second coupling ear are provided on the distal side of the base plate and the first and the second coupling area of the bridging element are adapted for coupling with the first and second coupling ear, respectively.
  • the looped rings may of course also be provided on the ostomy appliance for the purpose of supporting a support member according to the invention. This provides an easy coupling between the support member and the rest of the ostomy appliance by using features already provided on many common well-known ostomy base plates
  • first and the second coupling ear may be in the shape of first and second looped rings, whereby the first and the second coupling areas may advantageously be in the form of first and second hooks having a size allowing them to couple with the looped rings.
  • the support member further comprises at least one interposed element arranged between the base plate and the collecting bag, and the bridging element is adapted to be coupled to the interposed element at the respective first and second coupling areas.
  • the interposed element can in many regards be viewed as an adapter to allow the bridging element to be coupled to the ostomy appliance.
  • the interposed element has means for coupling to the area between the base plate and the collecting bag and also has means for coupling to the bridging element.
  • the at least one interposed element is in the form of a flange element having an annular mounting opening with a diameter which is larger than the diameter of the through-going hole and the opening.
  • the flange element can be mounted around the coupling between the base plate and the collecting bag.
  • the at least one interposed element is provided as two adapter elements each having a bridging coupling area for coupling with the respective first and second coupling area of the bridging element and a plate coupling area for coupling with the base plate.
  • the support member can be formed as one piece.
  • the first part of the support member comprises a flange element comprising an annular mounting opening with a diameter larger than the diameter of the through-going hole and the opening in the proximal wall and wherein the support member further comprises a bridging element extending from a first attachment area towards a coupling area, wherein the attachment area and the coupling area is separated by an intermediate section forming the second part of the support member.
  • the at least one interposed element comprises one or more removable elements making the diameter annular mounting opening therein size- adaptable. These elements may be in the form of one or more annular rings in the interposed element that may each be individually removable so as to provide the possibility of adapting the annular mounting opening in the interposed element according to the size of the through-going hole and the opening of the ostomy appliance of an individual user.
  • the annular rings may be essentially punched out in advance and/or may only be withheld in the interposed element by a small amount of material in one or more retention areas.
  • the annular rings may have weakened annular lines between them so that they will be easily pressed out by the finger force of a user.
  • the removable elements make the diameter of the annular mounting opening in the interposed element size-adaptable according to individual needs.

  • the respective ribs are placed apart from each other along the edge, thereby creating a fork-like configuration at each end.
  • the flange element 20 is in the form of an annular ring 21 having a first through- going hole 22.
  • a first and a second radially protruding gripping part 23, 24 are provided on diametrically opposed side of the annular ring.
  • the first and second gripping parts are formed of a first and second gripping flange 25, 26 that protrudes radially from the annular ring and is in the same plane as the annular ring.
  • a respective first and second angled gripping flange 27, 28 extends from the first and the second gripping flange at an angle a1 , a2 between the surfaces of the respective gripping flanges and angled gripping flanges.
  • the angles are preferably below 90° so that the angled gripping flanges extend backwards towards the annular ring.
  • the angle between the respective gripping flanges and angled gripping flanges provides respective first and second receiving grooves 29, 30.
  • the respective ribs of the edges of the bridging element are spaced apart with a distance that is greater than the length of the receiving grooves, corresponding to the width of the respective gripping flanges. Moreover, the length of the bridging element, from edge to edge, is longer than the distance between the first and the second receiving grooves 29, 30.
  • the support member is assembled by placing the edges of the bridge element in respective first and second receiving grooves, thereby forming respective coupling means.
  • the bridging element is flexible and/or resilient, it will bend due to the longer length and arch away from the plane of the annular ring of the flange element, wherein the coupling means are also arranged.
