Device for vacuum-sealing an injury

Device for vacuum sealing a wound, comprising:

• a film adapted for covering and forming an airtight seal over a wound,
• a drainage tube having a proximal end and a distal end, of which the distal end is adapted to being introduced below the film in the wound for forming a vacuum between said film and said wound, and
• a container for collection of wound secretion connected to the proximal end of the drainage tube, and wherein said container (20) is constructed to have a variable internal volume,
• wherein the internal volume of the container (20) is defined by a floor (64), an upper lid (68) and a deformable wall (70, 86), wherein the container (20) comprises a floor (64) movable with respect to said lid, wherein the wall (70, 86) sealingly connects the floor (64) with the lid (68),
• wherein a bellows (72) is provided between the lid (68) and the floor (64) which bellows (72) is capable of being placed under pneumatic pressure to thereby increase the internal volume of, and create a vacuum in, said container (20), and wherein at least one of said lid (68) and said floor (64) is adapted for receiving a gas cartridge (76) such that said gas cartridge (76) is in communication with the inside of said bellows (72).
