摘要： A measurement device is provided that determines fluid properties from vibration frequencies of a sample cavity. The measurement device includes a sample flow tube (108), a vibration source (110) and a detector (112) mounted on the tube, and a measurement module. The sample flow tube receives a flow of sample fluid for characterization. The measurement module employs the vibration sources to generate vibrations in the tube. The measurement module combines the signals from the vibration detector on the tube to determine properties of the sample fluid, such as density, viscosity, compressibility, water fraction, and bubble size. The measurement module may further detect certain flow patterns such as slug flow, for example. To measure the sample fluid density, the measurement module determines the resonant frequency of the sample flow tube. The density can then be calculated according to a formula that compensates for the temperature and pressure of the system. Other fluid properties may be determined from the sample tube's resonance peak amplitude, peak width and/or peak shape. Variation of the density measurements may be used to detect and characterize multiple phase fluid flow. The use of a vibration source and detector are arranged in a manner that greatly enhances the accuracy and reliability of the measurement device over a range of temperatures, pressures, and shock accelerations such as those that may be found downhole in a well.

摘要翻译： 提供了一种测量装置，其从样品腔的振动频率确定流体特性。 测量装置包括样品流管（108），安装在管上的振动源（110）和检测器（112），以及测量模块。 样品流管接收用于表征的样品流体流。 测量模块采用振动源在管中产生振动。 测量模块将来自振动检测器的信号组合在管上，以确定样品流体的性质，例如密度，粘度，压缩性，水分和气泡尺寸。 测量模块可以进一步检测某些流动模式，例如，团状流。 为了测量样品流体密度，测量模块确定样品流管的共振频率。 然后可以根据补偿系统的温度和压力的公式计算密度。 其他流体特性可以从样品管的共振峰值振幅，峰宽和/或峰形来确定。 密度测量的变化可用于检测和表征多相流体流动。 使用振动源和检测器以这样的方式布置，其在一定范围的温度，压力和冲击加速度（例如在井中可能被发现的冲击加速度）内大大提高测量装置的精度和可靠性。

摘要： A blood coagulation analyzer, such as the Thrombelastograph® (TEG®) blood coagulation analyzer is utilized to measure continuously in real time, the clotting process from the initial fibrin formation, through platelet-fibrin interaction and lysis to generate blood coagulation parameters. The measured blood coagulation parameters permit confirmation of the attainment of therapeutic level of GPIIb/IIIa receptor blockade, individualized dosing assessment to evaluate attainment of adequate GPIIb/IIIa receptor blockade; individualized dosing assessment required to reach adequate GPIIb/IIIa receptor blockade; illustration of the rate of diminishment of platelet inhibition or inhibition recovery after treatment with platelet-inhibition drugs; evaluation of the interaction effect of a combination of thrombolytic or any other agents or conditions effecting hemostasis and platelet-inhibiting agents on patient hemostasis.

摘要： A procedure for hemostasis and blood management, particularly for cardiovascular procedures, provides: sampling instructions, i.e., when to draw blood samples and how to pre-treat the blood samples, a decision tree to assist the interpretation of hemostasis analysis results allowing for the identification of various coagulopathies, and treatment suggestions related to the hemostasis analysis results. The analysis, interpretation and identification may be conducted by a suitably programmed computer.

摘要： In order to guide a liquid, a measuring transformer comprises a measuring tube (10) which vibrates in operation and is driven by an excitation arrangement (40). Oscillations on the inlet side and outlet side of the tube are detected by means of a sensor arrangement (50). In order to produce shearing forces in the liquid, the measuring tube (10) is at least temporarily excited during operation in order to create torsional oscillations about an imaginary measuring tube longitudinal axis (L). Said measuring transformer also comprises a torsional oscillation damper (60) which is fixed to the measuring tube (10) and, during operation, oscillates with the torsionally oscillating measuring tube (10). In this way, counter-torques created at least partially compensate the torsional torque created in the vibrating measuring tube (10). Said measuring transformer is characterised, inter alia, in that, during operation, it is largely dynamically counterbalanced even in the event of varying liquid densities or viscosity.

摘要： A method and device for blood hemostasis analysis is disclosed. A blood sample is displaced to reach a resonant state. The resonant frequency of the blood sample is determined before, during and after a hemostasis process. The changes in the resonant frequency of the blood sample are indicative of the hemostasis characteristics of the blood sample.
