Abstract
A drainage device (1) particularly for aspiration in case of therapies with aspiration, fistulas, dehiscences of surgical wounds, bedsores, traumas and similar lesions, comprising an aspiration pouch (2) which is supported by a sheet-like element (5) which can be associated with the lesion (10) and is connected to aspiration means (3) by way of a connecting element (4).
Claims15
A drainage device comprising an aspiration pouch supported by a sheet which comprises a hydrocolloid substance, the sheet being arranged on a bottom side of the aspiration pouch and overlapping at least partially the aspiration pouch, wherein
- the aspiration pouch comprises a gas- and fluid tight foil that encapsulates at least one draining layer, and
- the aspiration pouch is connectable to aspiration means by way of a connecting element which is provided outside the foil and on the top of the draining layer such that, in use, the draining layer is arranged between a cavitary lesion and the connecting element,
- the draining layer is formed of a porous material adapted to absorb fluid out of the cavitary lesion,
- the gas- and fluid tight foil includes a first opening that is reinforced by the sheet supporting the aspiration pouch,
- the sheet includes a second opening,
- the first opening and the second opening allow direct and uninterrupted communication between the draining layer and the lesion, and
- the foil partially encloses the draining layer on the bottom of the draining layer and extends radially inwardly so as to cover at least partially the bottom of the draining layer.
4 more elements
A drainage device comprising:
- an aspiration pouch;
- a sheet supporting the aspiration pouch, the sheet comprising a hydrocolloid substance and being arranged on a bottom side of the aspiration pouch and overlapping at least partially the aspiration pouch;
- a draining layer encapsulated by a gas- and fluid-tight foil defined by the aspiration pouch, the draining layer comprising a porous material for absorbing fluid and having a first surface facing the sheet and an opposing second surface facing away from the sheet;
- and
- a connecting element provided outside the foil and on the second surface;
- wherein the draining layer provides a cushion between the connecting element and the sheet;
- wherein the gas- and fluid-tight foil includes a first opening that is reinforced by the sheet supporting the aspiration pouch;
- wherein the sheet includes a second opening,
- wherein the first opening and the second opening allow direct and uninterrupted communication between the draining layer and the lesion,
- wherein the drainage device further comprises a further sheet with a third opening,
- wherein the third opening is aligned with the first and second openings,
- wherein the further sheet has a first outer contour;
- wherein the aspiration pouch has a second outer contour;
- wherein the first outer contour is larger than the second outer contour, and
- wherein the sheet is located between the further sheet and the aspiration pouch.

A drainage device comprising:
- an aspiration pouch;
- a sheet supporting the aspiration pouch, the sheet comprising a hydrocolloid substance and being arranged on a bottom side of the aspiration pouch and overlapping at least partially the aspiration pouch;
- a draining layer encapsulated by a gas- and fluid-tight foil defined by the aspiration pouch, the draining layer comprising a porous material for absorbing fluid and having a first surface facing the sheet, an opposing second surface facing away from the sheet, and a side surface extending between the first and second surfaces;
- and
- a connecting element provided outside the foil and on the second surface;
- wherein the gas- and fluid-tight foil includes a first opening that is reinforced by the sheet supporting the aspiration pouch;
- wherein the side surface of the draining layer defines a first outer contour;
- wherein an outer perimeter of the sheet defines a second outer contour;
- wherein the second outer contour is smaller than the first outer contour;
- wherein the sheet includes a second opening, and
- wherein the first opening and the second opening allow direct and uninterrupted communication between the draining layer and the lesion.
