Abstract: The method and the device are used for evaluating recorded measurement data. In particular, the use of the method and of the device makes it possible to detect the individual risk of a living being in respect of certain disease states and, if appropriate, to automatically evaluate correspondingly recognized risks in a device control. Measurement data in respect of heart-specific and/or circulation-specific parameters or respiration-specific parameters of a patient are preferably recorded and evaluated. The measurement data are determined over a defined period of time and the measurement data are evaluated taking into account the time information. A particularly effective implementation of the method can be based on pattern recognition in which individual patterns and/or sequence patterns are evaluated.

Abstract: The method and the device are used for updating a medical apparatus that has a memory for an operating program. The memory is at least partially designed as a variable memory and is connected with an input device for a current operating program. The memory and the input device are connected to control devices, which have testing means for evaluating at least one code. At least one function of the apparatus is released only when the code agrees with a reference value.

Abstract: The device serves to optically determine physiological variables in perfused tissue. The device comprises a first and a second light source which each emit light radiation of a first or a second predetermined wavelength. The light sources are arranged in such a manner that the light radiation exiting them can penetrate into the perfused tissue. At least one photodetector is used, which is arranged so that it detects the light emitted by the light sources and passing through or backscattered by the perfused tissue. The device also comprises a control unit, which furnishes control signals to the light sources so that the light sources continuously emit light alternately, one or more dark phases can be inserted into this sequence, during which at least one light source does not emit any light.

Abstract: The invention relates to a method and a device for operating or controlling respiratory equipment. According to the invention, a respiratory gas source, which can be connected to a patient interface, is coupled to a control unit. The control unit is configured to specify at least two different respiratory modes. The various respiratory modes are determined, selected and used for at least some respiratory disorders according to a current patient-specific requirement. The control unit is configured to automatically execute the control operations.

Abstract: The procedure and the apparatus serve for the control of a respirator device which is used for the supply of breathable gas to a patient. At least one sensor for the capture of the time-wise evolution of at least one respirator-treatment parameter is provided. The sensor can be arranged in the area of an air delivery which encompasses a respirator device as well as a connecting installation. The sensor is connected to an analyzer which carries out a pattern recognition and which is connected to a control for the modification of at least one respirator-treatment parameter. In order to implement the pattern recognition, one captures—at least at intervals—the time-wise evolution of at least one of the respirator-treatment parameters.

Abstract: A method and a device for the identification of at least two substances of content of a body fluid, wherein adjacent to a body tissue containing the body fluid, are arranged at least one radiation source and a photo receiver. The radiation source generates radiation of two different wavelengths. The radiation is directed onto the body tissue and the photo receiver receives radiation reflected by the body tissue and/or reduced through the body tissue. At least at times the radiation of a third wavelength is directed onto the body tissue for the identification of a hemoglobin derivate.

The radiation source generates radiation of at least two different wavelengths and the radiation is directed onto the body tissue.

At least at one point radiation from two radiation sources with an essentially same wavelength is directed essentially simultaneously onto the body tissue for penetration and/or reflection.

The control system is provided with an analyzer for determining at least one event related to the flow of respiratory gas.

Abstract: A display is connected to at least one sensor for detecting and transmitting physiological measurement values. In addition, one or more displays are used to present the measurement values and/or other associated data visually, acoustically, mechanically, or in some other way perceptible to the senses. A sequence control approach is implemented, according to which the measurement value, before reaching the display, passes through a testing stage, which, on the basis of at least one measured or stored additional value, verifies, checks, or changes the physiological measurement value detected at the sensor or supplements it with additional information. In a process for the noninvasive determination of the oxygen content CaO2 of human and/or animal tissue, the blood oxygen saturation and data on the blood hemoglobin concentration are obtained after the measurements have been acquired by the use of radiation with wavelengths in the range of 400-1,800 nanometers.

Abstract: For detecting and processing a physiological variable, a signal transmitter has devices for processing, using, and/or providing signals, which are generated from measurement values of the physiological variable. In accordance with a sequence control approach, the measurement values are acquired from the detection of electromagnetic waves of different wavelengths. Before the signals are detected, the electromagnetic waves pass through the medium to be examined or are reflected by this medium. For at least a certain percentage of the overall signal quantity, at least two measurement values detected close together in time are used for each generated signal. The signal transmitter is suitable for use in a control circuit, which is designed with an actuator to influence the physiological variable detected instrumentally by the signal transmitter.

Abstract: The method and device serve to measure a proportion of constituents in blood. To this end, electromagnetic radiation of different radiation wavelengths is directed through a tissue (9) containing blood vessels (1). At least a portion of the radiation exiting the vessel is detected using sensors, and a corresponding measured value derived therefrom is fed to an evaluating device. The evaluating device (10) is connected to at least two sensors (2, 3, 4) and has an analyzer (11) for determining a dispersion of radiation by evaluating the intensity of the radiation received by the individual sensors. An individual calibration determination is carried out by evaluating the angle-dependent dispersion and can be drawn upon for conducting a pulse spectroscopic determination of concentrations of substances.
