摘要
Drainage device (100; 200; 300) for the treatment of wounds with the use of negative pressure, which has: - a gas-impermeable wound covering element (3), composed of sheet-like material, which in the state which is applied to the patient's body is adhesively fixed around the wound area to the skin surface and forms a waterproof wound space (5), which is between the respective wound and the covering element (3) of wounds, - at least one flexible drain tube (4) that can be connected to a medium that generates the negative pressure, such as a vacuum pump (14), which can be inserted approximately parallel to the element (3) of covering of wounds in the wound space (5), through which substances in the wound space (5) can be evacuated, - and at least one absorption body (2) that aspirates the wound secretions , arranged within wound space (5), characterized in that - the absorption body (2) is at least one layer (7) enclosed in a shell (6), of a textile portion (33) interspersed with superabsorbent particles, the shell (6) being ) permeable to liquids and presenting pores, whose size does not essentially exceed that of the superabsorbent particles, - the absorption body (2) to be placed in the wound space (5) has an initial volume (V1), which increases in the course of the absorption process and adopts a final volume (V2), so that the secretions of the wound absorbed (depending on the pore size of the shell (11)) remain within the body (2) of absorption and therefore below the wound covering element (3) until the absorption body is removed from the wound space.
