Problems solved by technology

When designing a skin adhesive one of the major issues is to keep the skin relatively dry underneath the adhesive to prevent maceration.
This may result in degradation of the skin's barrier function as well as bad adhesion of the device to the skin.
Additionally, they will both swell when getting in contact with the output.
Thus, the failure mechanism is the same for both adhesives and the added protection is limited.
Acrylic adhesives are known to cause allergic reactions on skin and are therefore problematic.
Furthermore, known secondary adhesives strip or otherwise damage the skin upon removal, which can be painful and discomforting to the user.

Embodiment Construction

[0010]The aim of the invention is to provide a body waste collecting device that includes a first adhesive and an additional second adhesive, wherein said additional second adhesive comprises a polyalkyleneoxide polymer and an organosiloxane based cross-linked adhesive system.

[0011]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.

[0012]In an embodiment of the invention a body waste collecting device comprises a collecting pouch and an adhesive wafer for attachment to the body, said adhesive wafer comprises a backing layer, a first adhesive and an additional second adhesive, wherein said additional second adhesive comprises a polyalkyleneoxide polymer and an organosiloxane based cross-linked adhesive system.

[0013]The polyalkyleneoxide polymer and the organosiloxane based cross-linked ad...

Abstract

A body waste collecting device comprising a collecting pouch and an adhesive wafer for attachment to the body, said adhesive wafer comprises a backing layer, a first adhesive and an additional second adhesive, wherein said additional second adhesive comprises a polyalkyleneoxide polymer and an organosiloxane based cross-linked adhesive system.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a collecting device for attachment to human skin and for collecting bodily waste e.g. an ostomy device.BACKGROUND[0002]Collecting devices for collecting bodily waste, ostomy appliances, wound or fistulae drainage bandages or devices for collecting urine are usually in the form of a receptacle, e.g. a bag, pouch or tube for receiving the waste, connected to an adhesive wafer that can be attached to the skin of the patient. The wafer is typically in the form of a backing layer coated on the skin-facing surface with an adhesive layer and the wafer may further be provided with an aperture for accommodating the body opening. The size and shape of said aperture can often be adapted individually to fit the anatomy of the patient.[0003]One of the crucial part of such devices is the adhesive wafer. The wafer should be able to fit leak proof around the body opening, have good adherence to the skin without unintended detachment from ...
