    摘要： A body fluid measurement apparatus for continually monitoring the body fluids produced by a catheterized patient is disclosed. The apparatus comprises a discharge hose in fluid communication with the patient, a housing that supports the discharge hose, a dripping chamber for temporarily holding the body fluid while temperature and electrical conductivity measurements are made, a force transducer for producing a signal representing the weight of the body fluid mass collected, a container for collecting the body fluid that is suspended from the force transducer, a storage cell power source, and a computer for processing a signal generated by the force transducer, for generating a timing signal, and for computing the patient's body fluid volume flow in a certain time interval. All computed measurements are sent to a display also located on the apparatus. Additionally, two angle sensors, located in two planes orthogonal to one another, provide a signal to the computer for the compensation of the inclined position of the housing and for the compensation of an erroneous measurement of the weight of the body fluids collected. In addition, a method for the automatic monitoring and recording of the corrected volume flow of body fluids produced by a catheterized patient is also disclosed.

    摘要： This invention relates to the field of signal transit time sensors, in particular sensors based on ultrasonic transit times. Existing electronic control circuits for such transit time sensors for measurements on medical liquids, in particular blood, are extremely complex or their time resolution is limited. However, the present invention makes use of a simple measurement technique which cannot be used directly at first for the time resolution to be achieved. In this method, an ordinary sampling method is used to detect the received signal (12). An oscillator-like received signal (12) generated by an emitted step-like signal is first sampled during a half-period (14, 15) and is checked with the help of a selection criterion. Only when the result of this check is positive is at least one interpolated or extrapolated contact point (20, 21) of the received signal (12) with a resting level (11) determined in a received signal-time diagram with the help of which the signal transit time or the change in signal transit time is determined.

    摘要： Measuring device for determination of the activity or of the concentration of ions in solutions, which has an electrode block having several electrodes and with a flow channel, the flow channel being in connection at its one end with a sample vessel and is connected at its other end to a line, in which a pump is interposed, with calibrating solution containers.Between the pump and the outlet of the electrode block branches off a discharge line, in which a further pump is interposed. Preferably, both pumps are combined into a peristaltic pump, the lines being laid in the segments of the pump.According to a second embodiment, the electrode block is again in connection with the calibrating solution containers. The delivery of the sample is performed however on the same side through a septum. Advantageously, the other side of the electrode block opens out into a pressure equalization vessel, into which a withdrawal line opens in which in turn the above mentioned peristaltic pump is interposed.

    摘要： The invention relates to a drill (4) and a device or a method for drilling boreholes in workpieces (3), in which a periodically acting radial force (19) is exerted on the drill head (5) of the drill (4). The drill head (5) of the drill (4) has a cutting edge (52) extending only over a part of the diameter D(51) and is designed to have a lateral, V-shaped chip removing groove or bead (59) and with a channel (12) with an outlet opening (56) in the drill head (5) for supplying a drill fluid (9). On a drill side (61) of the drill head (5) opposite the bead (59) between a first and a second cylinder casing partial surface (64, 65) of the drill head (5) a rear offset (63) is formed which reduces the cross section of the drill head (5) in relation to an enclosing cylinder casing surface (61) of the drill head (5).
