Abstract
A pouch includes a front wall (22), a rear wall (24) having an entrance aperture (32), and a central partition (36). The partition divides the pouch into an entrance chamber (38) and a collection chamber (40) located one in front of the other. A pad (42) of superabsorbent material is located in the collection chamber (40) and extends above the lower level of the entrance aperture (32). In use, urine entering the pouch is directed downwardly and through a lower permeable region (36) of the partition, whereafter it is absorbed and gelled by the superabsorbent material pad. The urine is also wicked upwardly by the pad (42) so that the full height of the pouch can be used as a liquid-collection region.
Claims21
A pouch for collecting liquid excreted by a body, the pouch comprising:
- first and second walls defining a pouch envelope;
- a third wall for defining first and second chambers within the envelope and arranged with a portion of one chamber generally horizontally in front of the other when the pouch is in an upright orientation in which it is worn, the third wall including at least a portion thereof of a material porous to liquid;
- an entrance aperture communicating directly or indirectly with the first chamber;
- and
- a material in the second chamber for gelling liquid contents therein, for storing liquid in the second chamber as a gel;
- wherein the gelling material extends above the lower level of the entrance aperture when the pouch is in said upright orientation in which it is worn normally, whereby the gelling material is able to store liquid as a gel in an upper region of the second chamber above said lower level of the entrance aperture;
- the third wall being configured to admit liquid from the first chamber to the second chamber, and to obstruct the escape of gel from the second chamber, said third wall including a liquid impermeable portion and a liquid permeable portion.
