Disclosed is an ostomy device with an adhesive wafer for attachment to a skin surface of a user and a collecting bag for collecting output from a stoma. The collecting bag is connected to the adhesive wafer, and the adhesive wafer has a through-going hole for accommodating the stoma of the user. The adhesive wafer includes a backing layer, a first switchable adhesive composition (11), a second absorbent adhesive composition (12), and a release liner.

A parent artery occlusion (PAO) device which provides for immediate occlusion of a cerebral artery to isolate a defect. The PAO device includes a self-expanding wire-frame prolate structure which is partially covered with an ePTFE membrane.

A body side member of an ostomy appliance comprising a nonwoven element comprising a releasable material. Contact of the nonwoven element with liquid allow release of the releasable material from the nonwoven element. The releasable material may act to neutralise enzyme activity or pH of stomal exudate.

An ostomy device includes a nonwoven element having a water-soluble component and a releasable material. When the ostomy device is applied to a user and stomal output contacts the distal surface of the nonwoven element, the water-soluble component dissolves and releases the releasable material from the nonwoven element to neutralize at least one of enzyme activity and pH of the stomal output.

Disclosed is a moisture switchable adhesive composition including a polymer and a switch initiator. The composition can be switched from a first liquid state to a second adhesive state by activation of the switch initiator. The composition has in the first liquid state a complex viscosity |η*| below 0.4 MPa s; and the composition has in the second adhesive state a second repeated peel force above 1 N/25 mm.

A corrosion-resistant and leak-proof stoma paste with self-regulation of strength is provided in this disclosure, with a formula comprising 4-40 parts of liquid rubber with a molecular weight ranging from 2000 to 5000, 8-18 parts of mineral oil, 14-34 parts of iota-carrageenan, 10-20 parts of plant polysaccharide and 15-20 parts of sericite, by weight. A product of the present disclosure can self-regulate hardness of the paste according to amount of stoma excreta through cooperation of the iota-carrageenan and the sericite to improve corrosion resistance of the paste; and synergistic effect provided by the iota-carrageenan and the sericite powder can improve strength and corrosion resistance of the paste.

A pressure sensitive adhesive composition includes 4-15 w/w % styrene-isoprene-styrene copolymer, 20-35 w/w % styrene-isoprene diblock copolymer, 4-15 w/w % tackifier, 6-18 w/w % paraffin oil, and 30-45 w/w % hydrocolloid. The size of the hydrocolloid is below 40 μm.

Disclosed is a composition including a polymer and a switch initiator. The composition can be switched from a first liquid state to a second adhesive state by activation of the switch initiator. The composition has in the first liquid state a complex viscosity |η*| below 0.4 MPa s; and the composition has in the second adhesive state a second repeated peel force above 1 N/25 mm.

Provided is a conformable composition for skin application having good formability into a predetermined shape, good conformability to skin, and shape retention after the contact with water such as excretion without loss of its shape. The conformable composition for skin application includes a reinforcing component, a rubber adhesive component, and a hydrophilic polymer compound, or the conformable composition for skin application at least includes 1 to 20 wt % a reinforcing component, 40 to 90 wt % a rubber adhesive component, and 2 to 40 wt % a hydrophilic polymer compound.

Disclosed is abase plate 1 for an ostomy collection device, comprising a cover layer 2 whereon an adhesive layer 3 is at least partly disposed. Immediately surrounding a through-going hole 6, the base plate has an inner area wherein the cover layer extends beyond the adhesive layer in a radial direction toward the through-going hole, thereby providing an overlap 7 protecting the adhesive material from contact with stomal output.
