  • Patent number: 11621082
    Abstract: Data streams are received from each of the plurality of sensors. These data streams comprise varying values generated by in the sensors and characterize an associated physiological parameter. A parameter score is repeatedly determined for each physiological sensor that is based on whether the varying values for the associated physiological parameter deviate from at least one pre-defined threshold. A patient health index is repeatedly generated by combining each of the determined parameter scores to characterize an overall health of the patient. Data characterizing the patient health index is repeatedly provided. Related apparatus, systems, techniques and articles are also described.

  • Publication number: 20230039476
    Abstract: An automatic power on apparatus, system, method, and circuit automatically control the on/off state of a first electronic device or a second electronic device. When the second electronic device is positioned on, in, or proximate to the mounting area of the first electronic device, the automatic power on circuit establishes a coupling signal between a first portion of the automatic power on circuit and a second portion of the automatic power on circuit, activates the automatic power on circuit based on the coupling signal, and automatically controls an on/off state of the first electronic device or the second electronic device based on the activation of the automatic power on circuit.

  • Patent number: 11559642
    Abstract: An operating unit (2) sets ventilation parameters of a control unit (11) of a ventilator (1) that includes a gas dispensing device (10) for ventilation gases. The operating unit includes a display unit and an ventilation parameters input element (23, 24). Two or more of the parameters are linked via a relation condition stored in a relation storage module (40). A relation monitor (3) includes a deviation detector (31) detecting a transgression of the relation condition during parameter setting, and outputs warning information via a warning unit (32). This avoids a need for an operator to note the sometimes complicated connections and dependencies expressed in the relations during the parameter setting. The warning may be sent before the new setting value is sent from the operating unit to the control unit. Operating safety is increased and a risk of setting errors is minimized.

  • Patent number: 11555780
    Abstract: A photoacoustic sensor (100) is capable of detecting a predefined target gas in an area (Um). A process is capable of detecting the target gas with the use of such a sensor (100). A sample chamber (3) holds a gas sample (Gp) to be tested. Electromagnetic waves (eW) from a radiation source (1) pass through the sample chamber (3) and the detection chamber (4). The waves elicit in the detection chamber (4) an acoustic effect, which is measured by an acoustic sensor (7). The acoustic effect is correlated with the concentration of the target gas in the sample chamber (3). The detection chamber (4) is fluid-tightly sealed, is free from target gas and is filled with a replacement gas (Eg). The transmission of the replacement gas (Eg) has a spectral response similar to that of the transmission of the target gas in a predefined target gas wavelength range.

  • Patent number: 11530965
    Abstract: A monitoring device (1) for a system for generating medical compressed air includes a measured air line (3) removing compressed air from a compressed air supply line downstream of a compressed air conditioning unit. A sensor (2) generates a measured signal as a function of a property of the compressed air fed through the measured air line. A humidifier (8) humidifies the compressed air upstream of the sensor. An output unit (12) outputs information about the property of the compressed air to a user on the basis of the measured signal. A tap (4) removes compressed air and an actuator (5) changes a volume flow and/or mass flow of the compressed air, which volume flow and/or mass flow prevails in the measured air line. The actuator is inserted into the tap in a measuring mode and is removed from the tap in a compressed air removal mode.

  • Patent number: 11529052
    Abstract: A device, such as a data network device for a medical data network, controls an operating state of a second medical device in such a way that by sending a request message, the second medical device is prompted to change over into the operating state of the combined therapy and hence into an operating state in which its actuator is controlled as a function of an information signal of the first medical device. The information signal is based on physiological measured values. As a result, a clinician does not have to configure the second medical device himself/herself directly on site at the medical device by inputting an input signal, but this can be carried out by the device.

  • Patent number: 11481301
    Abstract: A medical device arrangement (100) tests processing of data sets to be processed during operation of the medical device arrangement. The arrangement includes a data interface (110), analysis modules (120) and a test module (130). The analysis modules process a received medical data set (105). Each analysis module (122, 123, 124) forms a processing instance (390) for the medical data set or for the medical data set (125, 125?) already preprocessed by at least one other analysis module. The test module outputs a test data set (132) to one of the analysis modules during operation such that this analysis module processes the test data set in the same manner as the medical data set. The test module compares a correspondingly outputted, processed test data set (134) with a reference result (136) associated with the test data set and determines a test result (137) based on this comparison.
