Disposable device for transferring and / or circulating an active liquid into and / or inside an intracorporeal the cavity.

摘要

Device (1) disposable for transferring and / or circulating an active liquid into and / or inside an intracorporeal cavity (2), said device being elongate along a reference axis (15), said device having one intrinsic axial consistency which is sufficient to allow said device to be introduced into said cavity by being pushed axially, said device comprising: - an expandable tampon (6) comprises at least one absorbent material, having a proximal portion (6c) and distal portion (6d), designed to collect and absorb said active liquid dispensed in the intracorporeal cavity (2) and to expand and supported in a sealed manner against the membrane (20) of the intracorporeal cavity mucosa (2); - a source (21) of liquid phase comprising a capsule (3) of which at least the proximal portion (3b) is surrounded at least partially by said expandable tampon (6); characterized by a coating (7) for the temporary protection covering at least partially the distal portion (3a) of said capsule, and extending longitudinally to an intermediate level of the buffer (6) such that it is formed in said buffer a proximal plug (8) not covered by said coating, which is at least radially expandable independently from the remaining part of said tampon.
