  • Patent number: 10010664
    Abstract: A life support system such as a heart-lung machine may include a plurality of medical devices a control panel and an excellent control position. The control panel may have separate control elements for operating the medical devices. The control panel may be constructed protruding essentially flat over a floor area of the majority of the medical devices. The control panel may be constructed to protrude in such a manner, that a control element, aligned only with a particular device and with the control position, is assigned to each device.

  • Patent number: 9927416
    Abstract: The present application relates to a method for controlling a disinfection status of a heater and/or cooler for human body temperature control during extracorporeal circulation. The temperature control is conducted by use of a heat exchanger and a temperature control liquid circulating through the heat exchanger and the heater and/or cooler. The inventive method comprises using a long term disinfectant in the temperature control liquid, measuring and preferably recording the concentration of the disinfectant in the temperature control liquid and deducing a disinfectant status of the temperature control liquid from the measured concentration of the disinfectant in the temperature control liquid.
