Article for absorbing a physiological liquid, such as a dressing
An article having properties allowing same to absorb a body fluid. The article includes at least three paths for the propagation of fluid from a fluid capture zone to at least one storage and/or evaporation area, each fluid propagation path being delimited by a fluid barrier preventing the passage of liquid from one path to another.
1. An article having bodily-fluid absorption properties, comprising at least three fluidic-propagation paths leading from a zone in which said fluid is collected to at least one retention and/or evaporation zone, each fluidic-propagation path being delimited by a fluidic barrier, the fluidic barrier opposing the passage of liquid from one fluidic-propagation path to another and extending between two adjacent fluidic-propagation paths, the fluidic-propagation paths being defined by a material containing absorbent fibers, and the retention and/or evaporation zone being defined by a material having a liquid absorption capacity greater than that of the fluidic-propagation paths.
2. The article as claimed in claim 1 , the fluidic barrier comprising an empty space or a hydrophobic material.
3. The article as claimed in claim 1 , said fluidic-propagation paths being defined by distinct elements of a transfer structure.
4. The article as claimed in claim 1 , the fluidic-propagation paths being defined by elements arranged with an angular offset about a center of the article.
5. The article as claimed in claim 4 , the fluidic-propagation paths being evenly angularly distributed.
6. The article as claimed in claim 1 , the fluidic-propagation paths being defined by elements that are separated by a layer of a material impermeable to water.
7. The article claimed in claim 1 , the fluidic-propagation paths being substantially parallel to one another.
8. The article as claimed in claim 7 , comprising two sets of fluidic-propagation paths leading between a common fluid collection zone and two respective retention or evaporation zones, each retention or evaporation zone being specific to one of the two sets.
9. The article as claimed in claim 1 , the retention or evaporation zone completely surrounding the collection zone.
10. The article as claimed in claim 9 , the retention or evaporation zone being concentric with the collection zone.
11. The article as claimed in claim 1 , the fluidic-propagation paths each opening at two opposite ends onto respective absorbent parts forming retention or evaporation zones.
12. The article as claimed in claim 1 , the fluidic-propagation paths being defined by elements that are at least partially superposed.
13. The article as claimed in claim 1 , constituting a dressing.
