Abstract: A dressing, comprising an inner layer and an outer layer; wherein the inner layer and the outer layer are aligned with trimming at one side of edge. The inner layer comprises hydrogel and meltblown nonwoven, and the outer layer comprises polyurethane film and pressure sensitive adhesive film. The dressing increases watertight closure. It could be applied in circular wound covering.

Abstract: A hydrogel structure which has: (a) a one way penetrating polyurethane film layer; (b) a hydrophobic pressure sensitive adhesive layer; (c) a multi-directional elastic meltblown nonwoven; (d) an interpenetrating polymer network; and (e) a hydrogel; wherein the meltblown nonwoven and the hydrogel are laminated by UV curing to form the interpenetrating polymer network, part of fibers of the meltblown nonwoven are exposed and fit stably with the pressure sensitive adhesive film. The hydrogel structure can make dressings multi-directional elastic for multiple traumas. The hydrogel structure can provide an environment suitable for wound healing, shorten the healing time, antiseptic and reduce the chances of being infected for the wound dressing.

Abstract: The invention relates to a moulding tool for producing a composite material part by coating, by means of a matrix, a flexible preform including a skin, and profiled elements delimiting a plurality of three-dimensional meshes of polyhedral shapes. This moulding tool comprises a mould and a countermould made of a material having the same expansion coefficient as the preform. Furthermore, includes, for each three-dimensional mesh, a part for filling the latter, formed from a plurality of wedges (12-27) suitable for being interlocked and delimiting a free central volume (28, 29), and from a blocking part (40) suitable for ensuring a relative blocking of said blocking part and of the wedges (12-27), the wedges and blocking parts being produced from a material having an expansion coefficient suitable for obtaining a predetermined compaction of is the preform for the polymerization temperature of the matrix.
