  • Publication number: 20240226402
    Abstract: A medical device, such as a hemodialysis machine or a peritoneal dialysis machine, is provided with control commands in a secure manner based on the commands being detected on a separate control component. The control commands are detected and thereupon a message is generated which contains a request to activate an operating element. Only if the indicated operating element has been activated is the control command forwarded to a dialysis machine for execution.

  • Publication number: 20230145918
    Abstract: A control device for a blood treatment apparatus, such as a hemodialysis machine, is programmed to be in signal communication with a data storage for transfer of first data. In addition, the control device is programmed to control or regulate the blood treatment apparatus based on a plurality of sequences included in the first data, after the first data has been transmitted from the data storage to the control device. Further, the control device is programmed to be in signal communication with a central unit. The signal communication serves for receiving second data from the central unit. The control device is further programmed to associate the received second data, according to a predetermined rule, with the first data and to load it from the data storage and to control or regulate the operation of the blood treatment apparatus based on this data.

  • Patent number: 10954575
    Abstract: A device and method for tempering sections of hot-formed and/or press-hardened metal components is disclosed having a support structure and a work head, the work head having at least one contact element consisting of an electrically-conductive material, for heating sections of a metal component using a flow of heat. Electrodes for resistively heating the contact element are connected thereto, and to a current source. A hot-formed and/or press-hardened metal component is first provided, and at least one contact element mounted on a work head is heated to a temperature greater than a target temperature to which a section of the metal component is to be heated. A contact surface of said contact element then comes into full-surface contact with the metal component section to be heated, with a predetermined pressing force, such that the metal component is heated to a target temperature in at least some sections by a flow of heat. The contact element is thus heated using resistive heating.

  • Publication number: 20170066030
    Abstract: A hot forming line for producing hot formed and press hardened sheet metal products made from metal plates includes a heating station and a forming station. The heating station has a bottom tool and an top tool between which a metal plate is received. The metal plate is heated in the heating station by indirect resistance heating. The heat is generated outside the metal plate and is transmitted by heat conduction into the metal plate itself. For this the bottom tool and/or the top tool has an electric resistance heating with at least one surface heating element. The surface heating element is a heating plate with a plate body made of an electrically conductive material, wherein the plate body is configured as heat conductor. For this the plate body is slotted and is for example provided with a slot, which extends over the thickness of the plate body.
