Abstract:
Objective To improve quota-sampling precision and reproducibility of the impedance blood rheometer. Methods Quota-sampling control circuit and the sampling needle's structure were improved for the early MVIS blood rheometer. The parameters of sampling were analyzed. Results After the improvement, the sampling errors were reduced obviously (less than ?3%). The quota-sampling handling was more accurater. Conclusion The precision and reproducibility of the blood rheometer are ensured.
