Embodiment Construction

[0099] In the drawings, the actual scale of different constituent elements is generally not emphasized for the sake of drawing clarity. Also, some elements may be shown with gaps although they are actually in contact.

[0100] Although based on Figure 1 to Figure 4 The article 10 of the present invention shown in is a bandage for application to a wound, but the entire description below is valid for articles other than bandages, especially for feminine hygiene products or disposable diapers.

[0101] For the sake of simplicity, the bandage is not shown with an outer protective layer in all the figures.

[0102] The article 10 comprises a proximal structure 20 intended to be in contact with the skin and a wound while being preferably centered on the wound; a distal structure 30 and an insertion structure 40 .

[0103] Each of the proximal, distal, and insertion structures may include one or more constituent layers that are permanently or non-permanently fitted together with a...

Abstract

The present invention relates to an item (10) having liquid (L) storage and / or discharge properties, in particular a bandage, comprising:—a liquid-permeable proximal structure (20), consisting of a material capable of inflating in the presence of liquid (L),—a distal structure (30) capable of draining a liquid (L),—a hydrophobic and non-absorbent spacer structure (40) extending between the distal (30) and proximal (20) structures, and being capable of locally limiting, when said material is not inflated, the exchange of liquid between the distal and proximal structures by maintaining a gap between said structures, and of authorising a local expansion of the proximal structure in at least one zone (P) where said material is inflated in response to coming into contact with a liquid, said expansion causing the proximal and distal structure to move together locally and the transfer of said liquid from the zone of the proximal structure (20) having undergone expansion to the distal structure (30).

Description

technical field [0001] The present invention relates to articles intended to come into contact with liquids via their proximal sides, especially liquids secreted by skin, wounds and / or mucous membranes, in order to control the spread and storage of these liquids, and more particularly, but not exclusively, to A dressing to be applied to a wound. Background technique [0002] The control of the spread of liquids and moreover their storage is a complex problem to be solved, for which the objects proposed in the field of bandages and hygiene products currently do not offer a fully satisfactory solution. [0003] These objects must actually meet specific requirements including opposing properties. The first requirement is to remove the liquids as far and as fast as possible in order to prevent any maceration or irritation at the skin, wound or mucosal level due to their accumulation. Liquids must not accumulate, but it is also preferable to avoid their lateral migration from t...
