Abstract
A blood testing device for detecting hemolysis in a blood sample is described. The blood testing device comprises an housing for containing the blood sample. The housing has a treatment window and an optical zone formed therein. The blood testing device further includes an acoustic transducer positioned to selectively generate acoustic forces directed into the treatment window of the housing and a control unit for selectively actuating and deactuating the acoustic transducer to permit colorimetric analysis of plasma within the blood sample.
Claims20
A blood testing assembly, comprising:
- a blood collection device, comprising:
- a first housing constructed of a fluid impermeable material and being partially constructed of a cylindrical shape having an internal cavity configured to receive blood, the first housing being a syringe or vacutainer;
- a treatment area supported by the first housing and defining a flow path in fluid communication with the internal cavity, the treatment area comprising:
- a treatment window adjacent to the flow path, the treatment window constructed of a material capable of passing acoustic forces into the flow path;
- an optical zone formed in the treatment window, the optical zone constructed of a material that allows a colorimetric analysis of a blood sample positioned within the flow path, and located adjacent to the optical zone;
- and
- a reader, comprising:
- a second housing having an opening and receiving at least a portion of the treatment area having the treatment window and the optical zone.
A method, comprising:
- passing blood from a housing of a blood collection device through a flow path and into a treatment area supported by the housing, a portion of the housing having a cylindrical shape, the housing being a syringe or vacutainer;
- separating blood cells from plasma within a blood sample in the treatment area supported by the housing into a first zone containing plasma and blood cells, and a second zone containing plasma and being substantially devoid of blood cells;
- and
- colorimetrically analyzing the plasma within the second zone to determine a degree of hemolysis within the blood sample.
