Patent ID: 7844325

Claim:
A bioelectricity impedance measuring device, which comprises: a housing with a contact surface capable of being placed on a part of the body; a handheld gripper configured to be easily grasped; electrodes facing the same direction from the contact surface of the housing; an operation and control device configured to measure a state of malnutrition from a phase angle theta and/or an RcXc ratio eta by a malnutrition measurement program; and a display which shows the measured state of malnutrition, wherein the operation and control device is configured to store values of Phase angle theta and/or an RcXc ratio eta in a data table as threshold values of Phase angle theta and/or values of RcXc ratio eta to measure a state of malnutrition from Phase angle theta and/or an RcXc ratio eta, wherein the values of Phase angle theta and/or RcXc ratio eta are equivalent to values of an upper arm circumference corresponding to several states of malnutrition determined by the Mid-Upper Arm Circumference (MUAC) method, and wherein the operation and control device thereby is configured to measure a state of malnutrition by comparing values of Phase angle theta and/or RcXc ratio eta calculated from measurement with the threshold values of Phase angle theta and/or RcXc ratio eta stored in the data table.
