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.

Claims (34)

1. A system for determining properties of at least one blood sample, the system comprising:

a receiver that detects a response resulting from an application of a signal to the blood sample and generates data quantifying the response to the applied signal; and

a processor and a memory in communication with the processor, the memory having computer-executable instructions comprising the steps of:

receiving, at the processor, the data quantifying the response to the applied signal, and

determining at least one hemostasis parameter and at least one oxygen transport parameter of the blood sample using at least a portion of the data, wherein determining at least one hemostasis parameter and at least one oxygen transport parameter further comprises adjusting the hemostasis parameter using the oxygen transport parameter.

2. A system of claim 1 , wherein at least some of the data is generated by an application of force to the blood sample.

3. A system of claim 2 , wherein the blood sample comprises a common sample portion and wherein the hemostasis parameter and the oxygen transport parameter characterize the common sample portion.

4. A system of claim 3 , further comprising at least one sample container that contains the common sample portion.

5. A system of claim 3 , wherein the common sample portion is an in-vivo blood sample.

6. A system of claim 2 , wherein the receiver detects the response by determining a displacement of the blood sample.

7. A system of claim 6 , wherein the application of a signal to the blood sample comprises an ultrasonic signal generated and directed at the blood sample to induce the displacement.

8. A system of claim 7 , wherein determining at least one hemostasis parameter and at least one oxygen transport parameter further comprises determining a stiffness of the blood sample using the data quantifying the response.

9. A system of claim 8 , wherein the data quantifying the response includes a backscatter of the ultrasonic signal applied to the blood sample, and wherein determining at least one hemostasis parameter and at least one oxygen transport parameter further comprises using the backscatter of the ultrasonic signal to determine the oxygen transport parameter.

10. A system of Claim 1 , wherein determining at least one hemostasis parameter and at least one oxygen transport parameter further comprises determining the oxygen transport parameter and the hemostasis parameter from a common portion of the data.

11. A system of claim 1 , wherein the oxygen transport parameter is at least one parameter selected from a group consisting of HCT, HGB, MCV, RBC, MCHC, MCH and combinations thereof

12. A system of claim 1 , further comprising a graphical user interface that displays the hemostasis parameter and the oxygen parameter simultaneously.

13. A system of claim 1 , wherein the application of a signal to the blood sample comprises generating an ultrasonic signal and directing the ultrasonic signal to the blood sample, and wherein the receiver detects at least one characteristic of the ultrasonic signal resulting from the application of the ultrasonic signal to the blood sample.

14. A system of claim 13 , wherein the computer-executable instructions comprise the step of determining using the at least one characteristic of the ultrasonic signal, the hemostasis parameter and at least one parameter selected from a group consisting of HCT, HGB, MCV, RBC, MCHC, MCH and combinations thereof

15. A system, comprising:

a memory; and

a processor in communication with the memory;

an acquisition module comprising computer-executable instructions, wherein said instructions comprise the steps of:

applying a signal to a blood sample,

measuring a response resulting from the applied signal, and

creating data quantifying the response; and

a processing module comprising computer-executable instructions, wherein said instructions comprise the steps of:

receiving the data quantifying the response from the acquisition module; and

determining at least one hemostasis parameter and at least one oxygen transport parameter of the blood sample using at least a portion of the data, wherein determining at least one hemostasis parameter and at least one oxygen transport parameter further comprises adjusting the hemostasis parameter using the oxygen transport parameter.

16. A system for determining properties of at least one blood sample, the system comprising:

a displacement means for causing a displacement within the blood sample;

a measurement means for measuring the displacement within the blood sample;

a data creation means for creating data characterizing the blood sample;

a processor means for receiving the data from the data creation means and determining at least one hemostasis parameter and at least one oxygen transport parameter of the blood sample using at least a portion of the data, wherein determining at least one hemostasis parameter and at least one oxygen transport parameter further comprises adjusting the hemostasis parameter using the oxygen transport parameter; and

an integrated means for facilitating determination of the at least one hemostasis parameter and at least one oxygen transport parameter.
