摘　　要：目的:改进电阻抗血液流变仪定量进样的精确度和重复性。方法:对早期生产的MVIS型血液流变仪定量进样控制电路和进样针结构分别进行改进,并对进样量进行参量分析。结果:改进控制电路和进样针后,取样误差明显减小(<±3%),定量进样准确。结论:确保了血液流变仪定量进样的精确度和重复性。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 rbeometer. 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.[Chinese Medical Equipment Journal, 2008,29 （12） ： 57-58]
