摘要： In an exemplary embodiment, the liquid pressure to be measured is in a liquid container with an inner tube forming a measuring cell arranged in an outer tube, which measuring cell can be filled in part with a liquid and in the remainder with a gas. A conduit that can be filled with the liquid leads away from the measuring cell, which conduit is open on its end facing away from the measuring cell and can be directly connected with the fluid in the liquid container. A transducer for generating an electric magnitude which corresponds to the gas volume in the measuring cell is arranged in the measuring cell. A channel is left free between the outer tube and the inner tube for the passage of the fluid. The inner tube is closed on its end facing away from the measuring end of the pressure transducer.

摘要： A method and apparatus for of assessing the blood concentration level in a human or animal subject, of a volatile blood constituent (preferably alcohol) is disclosed. The method comprises steps of positioning a sensor (21, 22) within the expiratory gas flow of the subject, wherein the sensor (21, 22) is configured to detect the presence of the constituent and provide a first output signal representative of the concentration of said constituent in air, and also to detect a presence of carbon dioxide and to provide a second output signal representative of the concentration of carbon dioxide in air. The flow of expiratory gases from the subject is sampled to provide a first signal and second signal in respect of the expiratory gases substantially simultaneously. The method also comprises the step of inputting said first and second signals obtained by the sampling step into an algorithm configured to compare the variation of the first signal over time with the variation of the second signal over time and, depending on the result of the comparison, to make said second signal representative of the degree of dilution of said expiratory airflow. The invention further includes an apparatus for carrying out the method.

摘要： An acoustic respiration detector includes at least two tubular air transmission lines having ends which are connected to microphone elements. Close to the other ends of the lines are openings at which turbulence, and hence acoustic signals, are created by the incidence of airflow caused by respiration. A holding element secures the openings relative to the mouth or nose of a patient whose respiratory function is to be monitored, and a flow directing element, for example formed like a face mask, directs the airflow to the openings. The microphone elements are connected in a bridge circuit with two voltage supplying leads and at least one signal lead. Thereby the sensitivity to mechanical and acoustic disturbances is suppressed.

摘要： In an exemplary embodiment, a measuring cell is formed by an interior tube open at one end and within a surrounding exterior tube. The interior tube is adapted to contain a gas while a chamber within the exterior tube at the open end of the interior tube can be filled with a pressure transmission liquid via a channel extending within the exterior tube and along the length of the interior tube and leading to the chamber. For a pressure measurement, the liquid in the chamber can communicate directly with a liquid in a liquid vessel, e.g. a blood vessel. In the measuring cell electrodes are arranged for generating an electric signal which corresponds to the gas volume in the measuring cell and thus the liquid pressure in the chamber. The measuring cell is disposed with its open end opposite a lateral opening in the wall of the exterior tube. The lateral opening communicates with the chamber at a location transversely offset relative to the open end of the measurement cell and disposed so as to facilitate and safeguard preparation of the device for a pressure measurement.
