Abstract: An apparatus for negative pressure treatment and instillation of wounds. The apparatus includes a dressing for covering a wound in a fluid-tight manner, a drain line for extracting fluid from the wound, a negative pressure unit for generating negative pressure in the drain line, an instillation line for providing an instillation fluid, an optional rinse line for providing a rinse fluid, and a main line connected to the dressing. The main line (60) has a single lumen and is connectable via a connection element (64) to two of the following lines, drain line (20), instillation line (40), and rinse line (50). Also, a method for operating this apparatus.

Abstract: The present invention relates to a device for the extraction of body fluid by suction, comprising a pump (2) with a pump housing (4) that comprises a suction opening (31), a container (6) with a container housing (8) that surrounds a reservoir (10) for storing the extracted body fluid and comprises an interface (84) in a container housing wall (82) for the communication between the suction opening (31) and the reservoir (10), a suction line port (74) that is connectable to a suction line (6) for the extraction of body fluid by suction, which is provided with a cover element covering the coupling device to improve the cleanliness and/or for the formation of functional surfaces for securing the suction line and/or releasing the coupling device.

Abstract: A device for supplying and/or aspirating a fluid substance to or from a human or animal body is provided, which device has a drive unit with a drive, an attachment part, and coupling element. The attachment part has a peristaltic pump unit with a pump head having roller elements which are movable freely and independently of one another and serve for rolling on a hose. The coupling element serves to transmit a movement from the drive to the pump head. The pump head has a decoupled state in which the roller elements apply no or a comparatively low mechanical pressure to the hose, and a coupled state in which the roller elements are pressed by the coupling element against the hose with a comparatively high mechanical pressure.

Abstract: A porous wound dressing for use in negative-pressure therapy is proposed. The wound dressing has an outer edge which defines a substantially oval or rectangular outer shape of the wound dressing with a major axis and a minor axis. The wound dressing has one or more incisions or perforations which together form one or more arc-shaped lines and serve for cutting the wound dressing to size in order to adapt the wound dressing to the shape and/or size of a wound. The one or more arc-shaped lines each extend asymmetrically with respect to the major axis and/or to the minor axis and each enclose, together with a portion of the outer edge, a segment of the wound dressing that is designed for separation from the wound dressing.

Abstract: Provided is a container for connection to a device for suctioning bodily fluids and for supplying a fluid substance to a human or animal body said container comprising an interior which is divided into a first region for collecting the suctioned bodily fluids and into a second region for providing the fluid substance The first region of the interior is separated from the second region by means of a flexibly realized partition wall

Abstract: A diaphragm vacuum pump has a pump chamber, a vacuum diaphragm for generating an underpressure in the pump chamber, an electric motor (1) with a motor shaft, a gear and a connecting element. The gear converts a rotational movement of the motor shaft into a cyclical, approximately linear forward and rearward movement of the connecting element, as a result of which the connecting element effects a cyclical movement of the vacuum diaphragm. The rearward movement of the connecting element per cycle is effected by a first rotation angle of the motor shaft which, on account of the gear, is not of the same magnitude as a second rotation angle of the motor shaft, wherein the second rotation angle effects the forward movement of the connecting element per cycle. The diaphragm vacuum pump according to the invention can be designed such that it is small and quiet and yet provides optimal power.

Abstract: Provided is a device for suctioning bodily fluids and for supplying a fluid substance to a human or animal body, in which the device includes a drive unit (1, 1?, 1?; 2) having a drive (20), a pump head (30, 30?, 30?) which is drivable by the drive (20) and a connecting part (5, 7?, 4?) which is releasably connectable to the drive unit (1, 1?, 1?; 2) and has a tube guide (555, 710?, 43?). The tube guide (555, 710?, 43?) is realized in such a manner for receiving a tube (I) that the tube, in combination with the pump head (30, 30?, 30?), forms a peristaltic pump (3) by way of which the fluid substance is conveyable through the tube (I) to the human or animal body. The pump head (30, 30?, 30?) is incorporated in the connecting part (5, 7?, 4?), and the drive unit (1, 1?, 1?; 2) includes a coupling element (24, 24?) which is connected to the drive (20) in order to couple the pump head (30, 30?. 30?) to the drive (20).

Abstract: A device for supplying and/or aspirating a fluid substance to or from a human or animal body is provided, which device has a drive unit with a drive, an attachment part which is attachable to the drive unit, and also a coupling element. The attachment part has a peristaltic pump unit with a pump head having one or more roller elements which are movable freely and independently of one another and serve for rolling on a hose. The coupling element serves to transmit a movement from the drive to the pump head. The pump head has a state in which it is decoupled from the coupling element, and in which the one or more roller elements apply no mechanical pressure or a comparatively low mechanical pressure to the hose, and also a state in which it is coupled to the coupling element, and in which the one or more roller elements are pressed by the coupling element against the hose with a comparatively high mechanical pressure.

Abstract: A gelling product for solidifying a body fluid aspirated in a fluid collection container has an interior, a gelling agent arranged in the interior, and a water-soluble cover. The water-soluble cover is made of a textile material. The gelling product, in particular a gelling bag, is in this way prevented from bursting too early.
