Background

The existing stoma adhesive disc is generally of a three-layer structure, namely a release layer, a back lining layer and a hydrocolloid layer, wherein the release layer is removed when the stoma adhesive disc is used, and the hydrocolloid layer is directly contacted with skin around a stoma, so that the stoma adhesive disc plays a role in sticking and plays a certain role in supporting and fixing; on the other hand, the hydrocolloid layer contains a certain amount of high molecular water-absorbing resin which can absorb the exudates from the stoma. Generally, in order to better adhere the skin, reduce the corrosion of exudate to an adhesive layer and reduce leakage, the viscosity of a hydrocolloid layer is high, tension damage may occur during adhesion, skin or residual viscose may be damaged during removal, and allergic inflammatory reaction around a stoma is easily caused during adhesion.

The existing stoma rubber disc has the main defects that: (1) The main components of the hydrogel layer are viscous rubber and a high-molecular water-absorbing material, so that allergic and inflammatory reactions around the stoma are easily caused; (2) When the hydrogel layer is too viscous, tension damage is easy to occur during use, and skin can be injured or residual viscose can be left when the hydrogel layer is removed, so that secondary damage is caused.

The utility model discloses further set up as the thickness of silica gel layer is 0.01-0.3mm.

The utility model discloses further set up as the thickness of hydrocolloid layer is 0.2-1.6mm.

The utility model discloses further set up to the material from the type layer is that white glassine leaves type paper, PE from type membrane or PET from type membrane.

The utility model discloses further set up to the material of back sheet is PE membrane, PE foamed plastic, EVA membrane, TPE membrane, PU membrane or EMA membrane.

Adopt the technical scheme provided by the utility model, compare with prior art, have following beneficial effect:

the use mode of the stoma rubber plate of the technical scheme is as follows: take off from the type layer after, the peripheral skin of mouthful is made in the direct contact of silica gel layer, hydrocolloid layer is not direct and make the peripheral skin contact of mouthful, when making mouthful sepage outflow, the sepage can flow to hydrocolloid layer through the hole, absorb the sepage by hydrocolloid layer, silica gel layer is good to skin adhesion performance, hydrophobic corrosion resistance is strong, close skin is soft, can keep making mouthful skin dry and comfortable around, can not arouse the tension damage when pasting simultaneously, can not cause skin damage and cull when taking off.

The ostomy adhesive disc can better reduce the allergic and inflammatory reaction possibly caused by the fact that the hydrocolloid layer directly contacts the skin around the ostomy, and reduce the complications of the ostomy patients; meanwhile, the tension damage caused by the overlarge viscosity of the hydrocolloid layer and the phenomena of skin pulling and adhesive residue when the hydrocolloid layer is removed can be well improved, the use defect of the existing pure water colloid stoma adhesive disc is overcome, and the life quality of a stoma wearer is greatly improved.
