Abstract

According to the impedance feature of biological tissue, the instrument was designed at 1, 5, 10, 50, 100kHz to measure human impedance, and then to calculate human FAT, FFM, FAT%, TBW, ECW, ICW and so on. A 8031 singlechip microprocessor contacuting used as a control center in the instrument. The part of electric circuit contacuting human body in the instrument was unreally earthing. The instrument was safty, effective, repeatable, and easily manpulative. Prelimintary clinical experiment showed the results measured with the instrument could effectively reflect practical, status of human composition.

摘要

根据生物组织的阻抗特性，该仪器设计在1、5、10、50、100千赫兹频率下测量人体阻抗，进而计算人体脂肪量、去脂体重、脂肪百分比、总体水量、细胞外液量、细胞内液量等。仪器采用8031单片机作为控制中心。仪器中与人体接触的电路部分不真正接地。该仪器安全、有效、可重复且易于操作。初步临床实验表明，用该仪器测量的结果能有效反映人体成分的实际状况。
