Abstract: A device is provided for acoustically reproducing the respiratory function for a respirator, with a patient respiration circuit. The device has a noise generator, a volume flow sensor device, which determines the volume flow in the patient respiration circuit and generates an electric signal representing the volume flow, and a volume flow evaluating unit, which is set up to pick up the volume flow signal and to generate a control signal for the noise generator as a function of this in such a way that an acoustic signal with a loudness rising (falling) with rising (falling) volume flow is generated.

Abstract: An electrode array is provided for a system for recording electrocardiogram signals. The array includes a sheet-like holding element, with a first electrode, a second electrode and a third electrode for connection to the skin of a patient. The electrodes are arranged at the holding element. A transmitting device is arranged at the holding element. A system is also provided for detecting electrocardiogram signals that includes the electrode array. The electrode array as well as the system for detecting electrocardiogram signals fastens a plurality of electrodes on the body of a patient without these having to be connected to one another based on the provision of a reference potential terminal (6). The reference potential terminal (6) is connected to the first electrode (3) and to the second electrode (4) and makes available a reference potential. The reference potential terminal (6) and the third electrode (5) are connected to the transmitting device.

Abstract: A respirator with active dehumidification of the breathing gas has a breathing gas cooler in the form of a Peltier element (16), whose warm side is arranged in the inspiration branch (4, 7) and whose cold side (18) is arranged in the expiration branch (5, 12).

Abstract: A method, system and device are provided for the determination of leaks in a respirator. An inspiration pressure pinsp is recorded during an inspiration time Tinsp with a measuring device. The inspiration pressure pinsp is varied during consecutive breaths I. Leaks are determined as to leak volumes VLi from the product of pinspi and Tinspi in accordance with the equation VLi=A×pinspiB×Tinspi while the parameters A and B are determined in an analyzing unit by a regression model with pinsp as the regressor.

Abstract: A method is provided for the contactless determination of the body core temperature of a person (7), wherein the surface temperature of the person (7) is detected at a measuring site (6) on the body by means of a temperature sensor unit (2) arranged at a spaced location therefrom. The sensor signal generated by the temperature sensor unit (2) is sent to an evaluating unit (3) for evaluating the sensor signal and for calculating the body core temperature, and the temperature signal generated in the evaluating unit (3) is sent to a display unit (4) for the optical display of the body core temperature determined. The temperature sensor unit (2) locally identifies a measuring area (8) on the body in a first step and the measuring area (8) on the body is resolved by the temperature sensor unit (2) in a second step such that the measuring site (6) on the body is detected and the detection is carried out by the temperature sensor unit (2) at this measuring site (6) on the body.
