  • Patent number: 8548759
    Abstract: Techniques (e.g., system, apparatus, method, machine-readable medium) can be configured for characterizing a rheological or other structural physical property of a sample of a substance. In an example, this can include acoustically bidirectionally deforming the portion of the sample over a deformation range about a neutral-deformation locus within the deformation range, measuring a deformation response of at least a portion of the sample to the insonification, and characterizing the physical property of the sample using the measured response of at least a portion of the sample to the insonification, even in the presence of a flowing substance.

  • Publication number: 20130190584
    Abstract: Methods, apparatus and systems for characterizing changes in at least one physical property of soft tissue. A series of acoustic pulses is generated and directed into the soft tissue such that at least one of the pulses is of sufficiently high intensity to induce physical displacement of the tissue. Waves reflected off the tissue, or a flexible member that moves with the tissue, are received and measured to estimate at least one characteristic of the physical displacement induced thereby. Repetition of the generating, receiving and estimating steps provides characterization of the at least one physical property over time. Methods, apparatus and systems for characterizing at least one physical property of blood, by generating a series of acoustic pulses and directing the series of pulses into the blood such that at least one of the pulses is of sufficiently high intensity to induce physical displacement of the blood.

  • Publication number: 20120294767
    Abstract: Provided are devices, systems and methods for the use of a portable unit for the evaluation of hemostasis. For example, a portable system for determining a plurality of hemostatic parameters may be included. The system includes a blood sample receptacle, an analyzer and a housing. The blood sample receptacle is configured to hold at least one blood sample. The analyzer is configured to determine at least two hemostatic parameters of the at least one blood sample. The housing is configured to operably couple the blood sample receptacle and the analyzer. The housing is portable and may, for example, have a thickness of 17.5 cm or smaller.

  • Publication number: 20120232803
    Abstract: An integrated system for determining a hemostasis and oxygen transport parameter of a blood sample, such as blood, is disclosed. The system includes a measurement system, such as an ultrasonic sensor, configured to determine data characterizing the blood sample. For example, the data could be displacement of the blood sample in response to ultrasonic pulses. An integrated aspect of the system may be a common sensor, sample portion or data for fast and efficient determination of both parameters. The parameters can also be used to correct or improve measured parameters. For example, physiological adjustments may be applied to the hemostatic parameters using a HCT measurement. Also, physical adjustments may be applied, such as through calibration using a speed or attenuation of the sound pulse through or by the blood sample. These parameters may be displayed on a GUI to guide treatment.

  • Publication number: 20110252352
    Abstract: A system for displaying a plurality of hemostatic indexes is disclosed. The system includes a communication receiver configured to receive the hemostatic indexes and a graphical user interface (GUI) connected to the communication receiver and configured to simultaneously display the hemostatic indexes. The hemostatic indexes are derived from a plurality of independent measurements, such as the mechanical measurements determined using the sonorheometry systems and processes.
