Abstract: Evaluation arrangement for a thermal gas sensor with at least one heater and at least one detector. The evaluation arrangement is configured to obtain information about an amplitude of a detector signal of a first detector, and information about a first phase difference between a heater signal and the detector signal of the first detector. In addition, the evaluation arrangement is configured to form as an intermediate quantity, dependent on the information about the amplitudes of the detector signal and dependent on the information about the first phase difference, a combination signal, and to determine information about a gas concentration or information about a thermal diffusivity of a fluid on the basis of the combination signal.

Abstract: A device for cardiopulmonary massage and/or resuscitation of a patient, which has a massage device arranged on a support board and includes a reversibly drivable massage stamp that can be positioned at a desired contact area on the thoracic cage of the patient for performing cardiopulmonary massage, and further includes a retention plate element which can be positioned on the thoracic cage of the patient at the desired contact area and which, by using at least three clamping elements engaging on its circumference, can be fixed, in particular can be connected to and braced by the support board. This has the effect that the mechanical cardiopulmonary massage can be maintained upright even during difficult transport maneuvers, since the relative position of the patient with respect to the massage device is not appreciably changed by its being clamped between the support board and the retention plate element.

Abstract: Gas sensor, including a membrane and a heating element arranged on the membrane between a first discontinuation area of the membrane and a second discontinuation area of the membrane. The first discontinuation area of the membrane includes at least one discontinuation of the membrane and the second discontinuation area of the membrane includes at least one discontinuation of the membrane. The gas sensor further includes a first temperature sensor structure arranged at least partially on the membrane on a side of the first discontinuation area of the membrane opposite to the heating element, and a second temperature sensor structure arranged at least partially on the membrane on a side of the second discontinuation area of the membrane opposite to the heating element.

Abstract: The invention relates to a stimulation device for electrotherapy, in particular a defibrillator device and/or external pacemaker device, comprising at least two contact electrodes, which can be applied to the body of a patient at suitable stimulation positions and by means of which current pulses can be applied to the body of the patient, the first of the at least two contact electrodes acting as a charging electrode having positive polarity, and the second of the at least two contact electrodes acting as a discharging electrode having negative polarity with respect to an emitted current pulse, and with a current pulse generator, which is or can be connected to the contact electrodes by means of line connections. The invention further relates to a method for determining the polarity of contact electrodes applied to the body of a patient.

Abstract: The invention relates to a stimulation device for electrotherapy, in particular a defibrillator device and/or external pacemaker device, comprising: at least two contact electrodes (11, 12), which can be applied to the body of a patient at suitable stimulation positions and by means of which current pulses can be applied to the body of the patient (10), the first of the at least two contact electrodes (11, 12) acting as a supply electrode (12) having positive polarity, and the second of the at least two contact electrodes (11, 12) acting as a removal electrode (11) having negative polarity with respect to an emitted current pulse; and a current pulse generator (14), which is or can be connected to the contact electrodes (11, 12) by means of line connections (21, 17).

Abstract: The invention relates to a sensor arrangement having a barometric pressure sensor and a thermal gas sensor, wherein the thermal gas sensor is arranged on the barometric pressure sensor or beside the barometric pressure sensor such that a gas-permeable measurement structure of the thermal gas sensor is arranged in front of a gas inlet opening of the barometric pressure sensor or in front of a pressure-sensitive surface of the barometric pressure sensor.

Abstract: The device according to the invention is used for a cardiopulmonary massaging and/or resuscitation of a patient and is provided with a massage stamp (17) which can be reversibly driven by a drive device in an actuation direction (18) and which has a pressure surface (31) that can be positioned at a contact region on the chest (12) of a patient (11). In order to ensure that the chest compressions are interrupted upon reaching a specified compression force, the massage stamp (17) has a stamp upper part (19) and a stamp lower part (20) which is operatively connected to the stamp upper part (19). The stamp upper part (19) and the stamp lower part (20) can be adjusted relative to each other in the actuation direction (18) at least between a first position which defines a working length (L) and a second position in which an effective length (1) of the massage stamp (17) is shortened compared to the working length (L).

Abstract: The apparatus of the invention is used for cardiopulmonary massaging and/or resuscitation of a patient and includes a massaging device (15) which can be reversibly driven in an actuating direction (23) by a drive unit (18) and which has a pressure surface (20) that can be placed in a target contact zone (21) on the rib cage (12) of a patient (11). In order to easily and reliably prevent the pressure surface of the massaging device to deviate from a target pressure point (21), the plunger (19) can be secured to the rib cage (12) of the patient (11) in the target contact zone (21) and is mounted in such a way as to be freely movable in a plane running transversely to the actuating direction (23) at least during an unloaded state between two massaging strokes.
