Abstract: A method for calibrating a gas analyzer (1). A gas analyzer is calibrated by measuring the zero level of the analyzer (1). The level of the analyzer is measured, after a preceding reset, whenever a temperature variation (.DELTA.T) of an infrared sensor (14) included in the analyzer (1) or of a component thermally connected in a highly conductive manner thereto exceeds a predetermined threshold value (A), or the temperature variation rate (D) of the infrared sensor (14) of the analyzer (1) or of a component thermally connected in a highly conductive manner thereto exceeds a predetermined limit valve.

Abstract: An apparatus and method for identifying containers (1) containing different anesthetic fluids. A connecting element (8) is used for coupling the container with a conduit (6) extending to a patient for supplying an anesthetic to a patient. The containers containing anesthetic fluids are designated or labeled distinctly from each other by means of at least one magnetic-field producing element (12). The presence of this element is in turn detected by means of a magnetic-field detecting element (13). The identification of a container containing an anesthetic fluid and, thus, an anesthetic fluid contained therein is effected by means of an identification element (15), which receives a signal from one or more magnetic-field detecting elements. The detection can also be used as a basis for establishing whether the container is coupled in its position.

Abstract: Liquid incursion into the gas analyzer or monitoring components of a gas analyzer of a variety employed in medical practice is prevented by a sequence of components performing under computer control. A liquid detector is positioned immediately downstream of the liquid separator/trap of the apparatus to detect any failure of that separating system. Should an incursion occur, the output of the detector will cause a safety valve to block further passage of materials into the monitoring components. The removable separator/trap components are monitored by interlock sensors. Upon appropriate signaling of such removal, a purging valve is actuated to employ atmospheric air made available by the removal of the separator/trap unit to purge the encroaching liquid from the forward components of the analyzer assembly.

Abstract: The invention relates to a method for the determination of the content of one or a plurality of gas components, e.g. carbon dioxide, present in the respiratory gas of a patient, especially in small children whose respiration is characterized by a high respiration frequency and a small respiration volume. The method is based on sucking, e.g. by means of a pump (8), into a tube (5) samples of the respratory gas of a patient from the phase of a respiratory cycle that is considered appropriate. In the determination of carbon dioxide content, the sampling is preferably effected as of the instant at which a flow reversal detector (4) fitted in tube (2) detects that a patient is inhaling or when the corresponding reverasl of flow has been detected in a respirator (3). In the determination of carbon dioxide content, the sampling must be stopped before the boundary zone of fresh incoming gas and exhaled gas, in inhalation reaches the end of sampling tube (5). Immediately after the preceding sample it is possible to suck into tube (5) the samples picked up from the following respirartory cycles. Thus, there may be a plurality of samples in successive order in tube (5) prior to their arrival at a gas component content measuring element (6).

Abstract: The inventon relates to a method and apparatus for marking or recording patient-related information and other necessary data in connection with X-ray imaging on a certain section of a film (6) by using a marking apparatus (2) which is movable relative to film (6). In the method, markings are made latent on film (6) in a manner that the markings become visible in connection with film development. The marking is effected as a sequence, line-directed deviation of a marking being obtained by moving the marking apparatus and the film relative to each other. The marking apparatus (2) used in the method is provided with marking elements which are brought into contact with film (6) for producing a marking on film (6), vertical deviation of alphanumerical marks included in a marking being achieved by individually controlling the operation of each marking element included in the marking apparatus. The marking apparatus of the invention includes marking elements and actuators for bringing the marking elements into contact with film (6) for marking the film. The apparatus further includes carrier assembly (8-10) for moving a marking apparatus (2) in the longitudinal direction of a slot (3) made in a film cassette (1).

Abstract: The invention relates to paramagnetic analyzer for measurement of oxygen contents of gas mixtures. The analyzer comprises electromagnet in a closed cavity controlled with chopped DC-current, sample and reference gas conduits entering the cavity and magnet core and common exit conduit. Gases are led to magnetic field in the gap between magnet poles through holes (13) and (14) drilled into the magnet core so that pedestals (15 and 16) in the gap guide gas flows to collide to be mixed. The mixed gas flows freely out from the gap to the surrounding cavity space (1).

Abstract: The invention relates to a method and system for detecting atrial arrhythmia, especially atrial fibrillations. Based on at least one electrical signal indicative of a heart's activity, a plurality of short-term HRV data sets are generated, one short-term HRV data set indicating the heart's rate variability within a time period of a given length, and two consecutive short-term HRV data sets having a given time difference. A frequency analysis of each short-term HRV data set is then performed and a power level corresponding to at least one selected frequency component in each short-term HRV data set is defined. The occurrence of the heart's atrial arrhythmia episodes are then estimated on the basis of the power levels defined.
