Problems solved by technology

Such adhesives need to be moisture absorbing to keep the skin dry, but absorbed moisture reduces the adhesive bonding to the skin.
When designing a skin adhesive, one of the major issues is to keep the skin relatively dry underneath the adhesive so as to prevent maceration.
Maceration occurs when the skin is unable to get rid of moisture from transpiration and results in degradation of the skin's barrier function as well as bad adhesion of the device to the skin.
Adhesives for fastening a bodily waste collecting pouch or tube are usually covered by a moisture impermeable layer that does not allow moisture from the skin to permeate through the adhesive and out into the surroundings.
The major problem in using an absorbing adhesive is that the bonding properties change as the adhesive absorbs moisture.
This effect is particularly a problem for hydrocolloid-based adhesives.
As the adhesive absorbs moisture from the skin, the hydrocolloids

Embodiment Construction

[0017]The aim of the invention is to increase the wear time of moisture absorbing adhesive wafer by moving the moisture absorption away from the skin-adhesive interface and further into the adhesive.

[0018]In an embodiment of the invention, a body waste collecting device comprising[0019]a collecting pouch[0020]an adhesive wafer for attachment to the body, comprising[0021]a backing layer[0022]at least one layer of absorbing material[0023]a skin facing layer of a low-absorbent, liquid impermeable, moisture permeable adhesive composition

[0024]By body waste collecting device is meant a device being able to collect and hold the output in a collecting item for a predefined time. The holding in place of the device may be obtained by a skin adhesive and the collection may be obtained by a bag.

[0025]In one embodiment of the invention, an adhesive composite is disclosed comprising at least two layers. The first skin-facing layer (1) has low moisture absorption capacity but can permeate moistur...

Abstract

A body waste collecting device comprising an adhesive composite that fastens a collecting bag to the skin is disclosed. The adhesive composite is highly moisture resistant while still being water absorbing. The adhesive composite comprises at least three layers, a backing layer, a moisture absorbing layer and a thin layer of vapour permeable, low-absorbing adhesive layer.

Description

FIELD OF THE INVENTION[0001]The present invention relates to an adhesive that attaches a collecting device to the human skin e.g. an ostomy device. Such adhesives need to be moisture absorbing to keep the skin dry, but absorbed moisture reduces the adhesive bonding to the skin. This invention discloses a body waste collecting device comprising an adhesive composite that maintains its adhesive properties even after considerable moisture absorption.BACKGROUND[0002]When designing a skin adhesive, one of the major issues is to keep the skin relatively dry underneath the adhesive so as to prevent maceration. Maceration occurs when the skin is unable to get rid of moisture from transpiration and results in degradation of the skin's barrier function as well as bad adhesion of the device to the skin.[0003]Usually, skin adhesive keeps the skin dry by being moisture permeable. This allows moisture to transport through the adhesive from the skin side to the opposite side, where it is allowed t...
