摘要:
A device is provided for measuring the velocity of flow of a fluid in a respiration system and includes a first thermal sensor element (5) provided with a controllable heating element (50) and a second thermal sensor element (6). The thermal sensor elements (5, 6) are arranged at spaced locations from one another at a path of flow, so that a thermal signal generated by the first sensor element (5) with the heating element (50) is transmitted to the second sensor element (6), and the second sensor element (6) is designed to detect the thermal signal from the fluid flow. The second sensor element (6) is connected to the first sensor element (5) via feedback (12) which triggers another thermal signal. A controlling and analyzing device (13, 15) is connected to the sensor elements (5, 6) to start the generation of a first thermal signal and to read and analyze the signal frequency as an indicator of the velocity of flow.

A cable for electromedical application and especially for recording the ECG of patients of different body shapes and body sizes is provided including a textile composite (1) formed of a carrier layer (2) and a cover layer (3). At least one electric line (4) is accommodated between the carrier layer (2) and the cover layer (3). After manufacture in a cost-effective manner, the cable offers sufficient protection against short circuits in case of penetration of moisture, on the one hand, and adapts to curved and irregularly shaped structures without problems, on the other hand. The cable textile composite (1) is flexibly deformable without destruction, wherein at least one electric line (4) is electrically insulated by an insulation (5) against the carrier layer (2) and the cover layer (3).

An anesthesia system for providing a breathing gas enriched with anesthetic has an anesthesia apparatus (2) and at least one anesthetic dispensing device (3), which is detachably coupled with the anesthesia apparatus. A fluid connection (7, 8, 9) is provided between the anesthesia apparatus and the dispensing device, which is designed to send anesthetic from the dispensing device into the anesthesia apparatus. At least one optical interface is provided between the anesthesia apparatus and the dispensing device. At least one display device is provided in the dispensing device. The optical interface has at least one light source (10), which is provided in the anesthesia apparatus, and at least one fiber optic light guide (20), which is provided in the anesthetic dispensing device (3). The light fed by the light source (10) into the fiber optic light guide is sent to the display device to directly or indirectly light the display device.
摘要:
A device for measuring the concentrations of paramagnetic gases in a gas sample has at least one modulatable magnetic flux source, which has an air gap, to which a gas sample can be fed. A controllable power source, for generating current and voltage signals, is coupled with the modulatable magnetic flux source in order to generate a modulatable magnetic flux within the air gap. Two measuring points are arranged at least partly within the air gap. Each measuring point has an electrically controllable heating device and a heat conduction-measuring unit or resistive measuring device. Each measuring point is coupled with a variable power source to heat the heating device to a working temperature. Each measuring point is coupled with a measuring circuit to measure heat conduction measured signals generated by the heat conduction-measuring unit, from which the concentrations of paramagnetic gases, which are contained in the gas sample, can be derived.

摘要:
A gas concentration-measuring device makes it possible to measure gas components in a gas sample. An interferometer, based on a dual-band Fabry-Perot interferometer (1), is provided with a transmission spectrum that can be set by a control voltage (38). The control voltage (38) of the dual-band Fabry-Perot interferometer (1) is synchronized over the course of time with the activation and deactivation of the radiation sources (11, 12).
