Definitions

  • the present invention relates to an ostomy appliance and to a method of applying an ostomy appliance body side member around a stoma.
  • Ostomy appliances are well known. Such appliances may be two-piece or one- piece appliances. In both types of appliances, an adhesive barrier member (or base plate) is attached to the wearer's abdomen/back/chest. In case of a one- piece appliance, a receiving member or bag is attached to the base plate. In case of a two-piece appliance, the adhesive barrier member forms part of a body side member and a receiving member or bag is attached releasably to the body side ostomy member for receiving exudates from the stoma.
  • an adhesive barrier member or base plate
  • a receiving member or bag is attached to the base plate.
  • the adhesive barrier member forms part of a body side member and a receiving member or bag is attached releasably to the body side ostomy member for receiving exudates from the stoma.
  • the whole appliance including the adhesive skin barrier securing the appliance to the skin is normally removed and replaced by a fresh appliance.
  • the body side ostomy member is left in place up to several days, and only the receiving member or bag attached to the body side member is replaced.
  • the attachment means for attaching an ostomy receiving bag may e.g. be a system se comprising matching coupling rings or matching flanges and adhesive surfaces engaging with and sealing against a flange area of the body side member.
  • Frequent changing of the body side member of a two-piece appliance is undesirable due to the irritation of the skin and the quality of life of the user may be improved and the nuisance of the wearing of an ostomy appliance reduced if the intervals between exchanging of body side member can be increased.
  • the service time of the body side ostomy member depends inter alia of the amount and the aggressiveness of the exudates and of the sealing between the stoma and the body side ostomy member.
  • the sealing depends on the fit to the stoma.
  • the resulting hole may show an exposed edge which may injure the surface of the stoma e.g. when the user bends or turns due to the exposed edge of the carrier sheet which after cutting even may show a serrated edge.
  • ostomy appliances comprising a body side member comprising an adhesive wafer for securing the appliance to the user's skin, said wafer having a hole for receiving a stoma, and an optionally separately exchangeable receiving member or bag secured to the body side ostomy member for receiving secretions from the ostomy said ostomy appliance further comprising a sealing member disposed in the hole of the wafer surrounding the stoma and having a hole for accommodating the stoma.
  • the ostomy appliance disclosed in Published International Patent Application No. WO 98/53771 has a sealing member having balanced plastic and elastic properties allowing a better adaptation of the hole of the ostomy appliance to a stoma by a temporary enlarging of the hole by everting or rolling up the inner rim of the hole for accommodating the stoma.
  • WO 98/17212 and WO 98/53771 only teach the use of such a sealing member together with two-piece ostomy appliances and do neither disclose nor indicate how to use a sealing member together with one-piece ostomy devices.
  • a sealing member If used with a one-piece ostomy appliance, such a sealing member would be difficult to manipulate for several reasons. Firstly, it is very difficult to adapt the sealing member to the stoma after applying the ostomy appliance if the sealing member has a tacky surface on the side facing the bag as it will then adhere to the bag during attempts to adapt the sealing member to the stoma which must be performed by pressing the wall of the bag against the sealing member. Then, also a risk exists that the wall of the bag is torn when trying to disengage the contact.
  • the invention relates to an ostomy appliance comprising a front wall and a rear wall of flexible material forming a bag, said rear wall having an opening for receiving a stoma, and said rear wall also being provided with an adhesive wafer for securing the appliance to a user's skin, said wafer having a first hole being aligned with the opening for receiving the stoma, wherein the opening has an edge being secured to the surface of the adhesive wafer facing away from the user in an attachment zone surrounding the hole of the wafer, said ostomy appliance further comprising a sealing member having a second hole for receiving the stoma and a flange projecting from an outer rim thereof.
  • am ostomy sealing member comprising a mouldable adhesive material which member shows adhesiveness to adhere to the skin of an ostomate and to seal around a stoma and between the stoma and an ostomy appliance adapted to receive secretions from the stoma and a sufficient cohesion to be removed in one piece without leaving remaining adhesive material on the skin, said sealing member having a hole for receiving the stoma and a flange projecting from an outer rim thereof.
  • the invention relates to methods of applying to an ostomate an ostomy appliance comprising a front wall and a rear wall of flexible material forming a bag, said rear wall having an opening for receiving a stoma, and said rear wall also being provided with an adhesive wafer for securing the appliance to a user's skin, said wafer having a hole being aligned with the opening for receiving the stoma, said opening comprising a sealing member having a second hole for receiving the stoma and a flange projecting form an outer rim thereof, wherein the opening of the bag has an edge being secured to the surface of the adhesive wafer facing away from the user in an attachment zone surrounding the hole of the wafer.
  • FIG. 1 shows a sectional view of an embodiment of an ostomy appliance of the invention after application to the skin of an ostomate
  • Fig. 2 shows a sectional view of another embodiment of an ostomy appliance of the invention after application to the skin of an ostomate
  • Fig. 3 shows collection bag for use as a part of an ostomy appliance of the invention in its open state

  • a simple evaluation of the stoma area for cutting the wafer for adapting the same to the specific stoma and manipulation and location of an adhesive wafer in relation to the stoma is enabled. All such adaptation and application may be carried out having full view over the stoma area from the distal side. Then, edge of the bag is easily sealed to the wafer along the remaining part of the attachment zone, and thus along the full periphery of the bag, using an adhesive.
  • the adhesive is preferably protected by a release liner until the final sealing of the bag.

  • a suitable adhesive material is a pressure sensitive adhesive suitable for use with the parts to be united such as acrylic ad- hesives, elastomeric adhesives, polyurethane adhesives, or polyester adhesives.
  • the choice of adhesive may be made in accordance with the above requirements, as it is not critical for the invention in the respect that the adhesive is not in contact with the skin. It is also contemplated that the adhesive properties of the adhesive and the second part of the edge of the bag or the stiffening element and the second part of the attachment zone are balanced enabling an opening and reseating of the bag, if desired.
  • the stiffening element is a flat ring provided with two notches dividing the flat ring into two parts.

  • the notches may be present on the proximal surface of the stiffening element of on the distal surface of the stiffening element whichever deemed most appropriate.
  • care must be taken when securing the edge of the bag to the stiffening element that the edge of the bag is reliably sealed to the surface without canals in the notch-area.
  • the securing may e.g. be effected by welding or suitably applying an adhesive, preferably in an amount ensuring a reliable sealing in the notch-area. A combination of a welding seam and adhesive sealing may be used if deemed appropriate.
  • notches stretch essentially along a chord of the circular ring facilitating the bending of the stiffening element.
  • the notches stretch essentially along a diameter of the circular ring giving a large opening to the stoma site in the ostomy appliance.
  • the part of the stiffening element secured the second part of the bag is provided with an adhesive layer being covered by a pro- tecling layer.
  • care must be taken to ensure that the notch is sealed reliably when adhering the second of the edge of the bag to the second part of the at- tachment zone, e.g. by applying a sufficient amount of adhesive material to fill the notch.
