Patent number: 9744299Abstract: A data processing device is provided for an anesthesia device for feeding an intravenously administered hypnotic, a volatile hypnotic, and an opioid such that the volume flow can be adjusted. The device determines and standardizes the effective concentrations of the anesthetics. A pharmacokinetic model adds up the standardized concentrations of the hypnotics to a total hypnotic concentration. An isobole is calculated based on a coordinate plane with a total hypnotic concentration axis and an opioid concentration axis, as a function of the currently determined concentrations. The system displays a two-dimensional action diagram with the y-axis as an indicator of the total hypnotic concentration and the x-axis as an indicator of the standardized opioid concentration. The calculated standardized total hypnotic concentration and opioid concentration and the isoboles determined are displayed. The display is adapted to changes occurring in the isoboles determined in the course of time.Type: GrantFiled: May 15, 2013Date of Patent: August 29, 2017Assignee: DRÄGERWERK AG & CO.

Patent number: 9737265Abstract: A patient monitoring device and method that determines and monitors at least one patient parameter is provided. A configuration processor generates configuration information in response to a first input signal and an adaptive notch filter receives a second input signal. The second input signal includes a signal of interest and an interference signal in a predetermined frequency range. The adaptive notch filter automatically estimates the interference signal within the second input signal based on a filter parameter and removes the estimated interference signal from the second input signal to generate a target signal. A step processor is electrically coupled between the configuration processor and the adaptive notch filter and sets a value of the filter parameter based on the configuration information, wherein the adaptive notch filter uses the filter parameter to reduce a ringing artifact on the target signal below a threshold level.Type: GrantFiled: April 20, 2012Date of Patent: August 22, 2017Assignee: Drägerwerk AG & Co.
