Abstract: The invention relates to an RF (=radio frequency) coil arrangement for an NMR examination apparatus, an object or target to be examined, e.g. a patient or part of a patient being adapted to be placed inside said coil arrangement which is adapted to excite the nuclei of a selected target area by transmitting an RF pulse substantially orthogonal to a homogeneous basic magnetic field produced by the apparatus and, thereafter, to receive and detect an NMR signal generated in the target. In order to eliminate the drawbacks of a so-called saddle coil conventionally used as an RF coil the invention is characterized in that it comprises a transfer line, continuous and wired in a manner that its various parts induce an RF field of different direction. Both in excitation and detection of signals, said transfer line can be adapted to process a magnetic field rotating in just one direction and it can be connected as an endless loop. Especially if a plurality of rounds are desired on an RF coil, a preferably and technically readily designable construction can be achieved by entwining the transfer line into a mesh shaped e.g. as a cylinder or a like body of revolution.

Abstract: The invention relates to a method of eliminating the effect of temperature, air pressure and/or a disturbing material component or a like parameter in photometric analysis in which is generated a so-called dark signal, the passage of emitted radiation for detection being blocked at that time, a reference signal for one or more material components to be measured, said reference signal not being affected by said material component to be measured, as well as for each material component to be measured a measuring signal representing the amount of material component to be measured. According to the invention, whenever the difference between a reference signal and a measuring signal changes due to a change in any of the above parameters, there is generated a control signal which represents said parametric change and is proportional thereto, said control signal serving to change the difference between a reference signal and a dark signal in order to compensate for said parametric change. The material components to be measured may preferably comprise CO.sub.2, N.sub.2 O and/or one or more anesthetic gases.

Abstract: The invention relates to a method of further developing the measuring of so-called neuromuscular transmission (or NMT), said measuring being effected by stimulating with electric pulses a given muscular nerve, e.g. the ulnar nerve in the arm of a patient, and by measuring a corresponding muscular block by means of EMG. In the prior art NMT-measurings, a stimulus artefact, caused by stimulation and induced directly electrically and independently of a stimulus passing through said muscular nerve, may often distort measuring results. According to the invention, this artefact is not tried to be eliminated by various gate solutions but, instead, it is measured by first effecting a measurement prior to the actual neuromuscular block measurements e.g. in connection with the calibration of the control or reference value of a muscular block and by recording or storing this first value of a stimulus artefact. This is followed by monitoring the changes of stimulus artefact values by measuring said stimulus artefact during the measurements of a neuromuscular junction and by comparing the thus obtained stimulus artefact values with said first value, not only for securing the reliability of measuring information but also preferably for controlling the state variations and condition of NMT-measuring instruments. By digitizing the collected information, the measuring errors can be preferably eliminated mathematically by utilizing data processing.

Abstract: A method of determining ventilation inhomogeneity in the lungs is provided. During the first step of the method, a lung volume series is calculated from a series of measured lung inert gas concentrations and lung inert gas volumetric change measured data series. As a second step, the series of lung volumes is completed with a series of value representing the total gas exchange efficiency in the lungs. A global inert gas dilution ratio may be used for this purpose. The gas exchange efficiency values are such that less ventilation is represented by lower numbers. As the third step, the gas exchange efficiency series is plotted as an ordinate and lung volume series as an abscissa to form a graph. From this graph both the lung volume and homogeneity of ventilation become directly apparent.

Abstract: A liquid reservoir for a nebulizer is comprised of a pair of membranes formed of resilient material and sealed about their edges to form a closed chamber between them for containing a liquid to be nebulized. When the chamber is filled with liquid and thereby expanded, the resilient membranes are distended to apply pressure to the liquid in the chamber. A discharge valve controls the discharge of liquid from the reservoir to the nebulizer under the pressure applied by the membranes. The reservoir is mounted on the nebulizer so that one of the membranes abuts a surface of the nebulizer that concavely deforms the membrane to increase the pressure applied to the liquid in the chamber to reduce or eliminate any residual volume of liquid in the chamber at the end of the discharging operation.

Abstract: An apparatus/method for detecting an empty breathing gas compartment condition in a bellows ventilator for a patient. The apparatus includes a first sensor for measuring, during inspiration, the incoming flow of gas into a driving gas compartment located in the bellows container. The second sensor measures the pressure in the driving gas compartment. During the inspiration cycle, measurements taken by the first and second sensors are signaled to a control unit and used to determine a .DELTA.V/.DELTA.p compliance value. The compliance value will be large if the bellows is movable, i.e. not in the empty breathing compartment gas condition. The compliance value is small if the empty breathing gas compartment condition exists. The compliance value, so determined, is compared with a reference compliance value in the control unit to detect the empty breathing gas compartment condition.
