Abstract
Devices and methods for calculating various coagulation characteristics associated with a patients liquid test sample. The presently disclosed and claimed inventive concept(s) relate to an improved device(s) and method(s) for conducting coagulation assays on a patients liquid test sample, including, without limitation, a patients whole blood sample.
Claims20
A coagulation device for the conductance of at least one coagulation assay on a patient's liquid test sample, comprising:
- a top section, the top section comprising at least one side, a top portion, and a bottom portion;
- a bottom section, the bottom section comprising at least one side, a top portion, and a bottom portion;
- a center section, the center section comprising at least one side, a top portion, and a bottom portion, the center section being disposed between the top section and the bottom section, the center section further comprising at least two channels, wherein each of the at least two channels comprises an opening in fluid communication with a sample receptacle for receiving a patient's liquid test sample, further wherein each of the at least two channels is open to the top portion of the bottom section and each of the at least two channels comprises a sample window containing at least one coagulation assay reagent for conducting at least one coagulation assay, the center section further comprising at least one spacer that completely separates each of the at least two channels from one another.
A method for measuring the coagulation characteristics associated with a patient's liquid test sample, the method comprising the steps of:
- obtaining a patient's liquid test sample;
- introducing the patient's liquid test sample into a coagulation device, the coagulation device comprising:
- a top section, the top section comprising at least one side, a top portion, and a bottom portion;
- a bottom section, the bottom section comprising at least one side, a top portion, and a bottom portion;
- a center section, the center section comprising at least one side, a top portion, and a bottom portion, the center section being disposed between the top section and the bottom section, the center section further comprising at least two channels, wherein each of the at least two channels comprises an opening in fluid communication with a sample receptacle a sample receptacle that receives a patient's liquid test sample upon introduction into the coagulation device, further wherein each of the at least two channels is open to the top portion of the bottom section and each of the at least two channels comprises a sample window containing at least one coagulation assay reagent for conducting at least one coagulation assay, the center section further comprising at least one spacer that completely separates each of the at least two channels from one another;
- reacting the patient's liquid test sample with the at least one coagulation assay reagent within each sample window of each of the at least two channels to thereby form a reacted sample;
- interrogating the reacted sample within each optical window with a specific wavelength of light emitted from an optical source, the interrogation occurring over a particular duration of time at predetermined intervals;
- measuring the reacted sample to determine a plurality of coagulation characteristics associated with the reacted sample.
