HAND-HELD TEST METER WITH PHASE-SHIFT-BASED HEMATOCRIT MEASUREMENT CIRCUIT |
摘要 |
<p>A hand-held test meter for use with an analytical test strip in the determination of an analyte in a bodily fluid sample includes a housing (110); a microcontroller block (112) disposed in the housing; and a phase-shift-based hematocrit measurement block (114). The phase- shift-based hematocrit measurement block includes a signal generation sub-block (120), a low pass filter sub-block (122), an analytical test strip sample cell interface sub-block (124), a transimpedance amplifier sub-block (128), and a phase detector sub-block (130). In addition, the phase-shift-based hematocrit measurement block and microcontroller block are configured to measure the phase shift of a bodily fluid sample in a sample cell of an analytical test strip inserted in the hand-held test meter and the microcontroller block is configured to compute the hematocrit of the bodily fluid sample based on the measured phase shift.</p> |
