Abstract: A barrier of a vacuum pump prevents contamination from entering a vacuum pump air line. The barrier separates parts of the pump and is moveable between an initial state and a distended state. The barrier is assembled within the pump with a pre-load. When the vacuum source is applied to the barrier, the barrier achieves a distended state and when the vacuum source is released, the barrier incrementally self returns to an initial state. The geometry and material construction of the barrier, along with the pre-load, assists in returning the barrier on its own to the initial state from the distended state.

The breast shield additionally comprises a flexible collar (2) which is arranged on the funnel (11) at an end of the funnel (11) remote from the connection piece (10) and which is realized to be placed onto the mother's breast. The named end of the funnel (11) forms a first contact surface (12) and an end of the collar (2) which faces the funnel (11) forms a second contact surface (22) and they both adjoin one another in an obtuse manner in a circumferential connecting joint (4), wherein the connecting joint is a butt joint.

Abstract: A device for aspirating body fluids and for supplying a substance to a human or animal body is defined. The device comprises a first pump (8) for the aspiration of the body fluids, and a second pump (3), or a coupling element (76?) for connecting a second pump (3?) in order to convey the substance to the body by means of the second pump (3, 3?). Moreover, the device comprises a drive (70, 70?) for driving the first pump (8). The same drive (70, 70?) which serves to drive the first pump (8) also serves to drive the second pump (3, 3?).

Abstract: The invention concerns a vehicle guided on a railway track comprising a chassis and at least one wheel assembly interconnected to the chassis and a method for steering said vehicle. The wheel assembly comprises a cross-member having a first end to which a first hub is interconnected by a first steering joint and a second end to which a second hub is interconnected by a second steering joint. A first wheel is attached to the first hub rotatable around a first rotation axis and a second wheel is attached to the second hub rotatable around a second rotation axis. A first sensor determines the lateral position of the first sensor with respect to the rail. The first sensor is attached to the first hub and is, with respect to a direction of travel arranged in front of the supporting area of the first wheel in a horizontal direction spaced a distance A1 apart.

Abstract: A method for operating a breastpump unit for expression of human breastmilk and various breast shields for use in this method allow a maximum pumping performance and a minimum pumping duration per pumping session. The breast shield has an inner chamber for receiving a nipple of the breast and also at least one outer chamber which at least partially surrounds the nipple. The inner chamber is subjected to a constant pressure and the at least one outer chamber is subjected to a pulsating pressure.

Abstract: An appliance is provided for negative-pressure therapy of wounds on the human or animal body in which, on the one hand, a substance is delivered to a wound bed (W) and, on the other hand, fluids, in particular an exudate and the delivered substance, are aspirated from the wound bed by negative pressure. The appliance has a suction pump housing, with a suction pump arranged therein for aspirating the fluids from the wound bed (W), and a fluid collection container for collecting the aspirated fluids. Moreover, the appliance has a first measuring device and a second measuring device. The first measuring device serves to determine the quantity of the aspirated fluids, and the second measuring device serves to determine the quantity of the substance delivered to the body.

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 mechanical fluid pressure modification valve, or “MFLP-valve”, is set forth. The MFLP-valve can be actuated upon movement of a movable pressure system member of a medical pressure system reaching a selected position. Additionally, the MFLP-valve can be actuated based on a pressure condition of the system. When the MFLP-valve unseals, a pressure differential between a pressure chamber and a volume outside of the chamber can be relieved. Disengagement of the movable pressure system member from the MFLP-valve can enable the MFLP-valve to re-seal. The MFLP-valve may include a flag that indicates the position of the movable pressure system member. The MFLP-valve may be provided in a diaphragm-type pressure source.

Further, the system includes at least one breast pump system communicably coupled to the data processing unit. Real-time changes to the breastpumping session are implemented to the breast pump system based on the analysis of the pumping data.

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.
