Abstract
Disclosed is a dividable apparatus for measuring living body impedance in which a first housing section 22 having a first current feeding electrode 4 and a first measurement electrode 5 mounted thereon can be physically separated from a second housing section 3 having a second current feeding electrode 6 and a second measurement electrode 7 mounted thereon, but said first and second housing sections 22, 3 are kept electrically connected to each other via an electric cable 11, whereby said first and second housing sections 22, 3 can freely be positioned on any parts of the body for impedance measurement.
Claims8
A dividable type apparatus for measuring a living body impedance of a living body, comprising:
- a first current feeding electrode, a first measurement electrode, a second current feeding electrode, and a second measurement electrode mounted on a housing;
- a measuring unit;
- a data input unit;
- an arithmetic unit;
- and
- a display unit;
- said housing comprising a first housing section having the first current feeding electrode and the first measurement electrode mounted thereon, said first housing section being of a compact size so that said first housing section can be held by the hand of a user for measurement, and a second housing section couplable to and separable from said first housing section and having the second current feeding electrode and the second measurement electrode mounted thereon, said second housing section being of a compact size so that said second housing section can be held by the hands of the user for measurement, said first and second housing sections being electrically connected to each other via an electric cable;
- wherein when said first and second housing sections are coupled to each other, the living body between the first housing section and the second housing section can be measured by holding the coupled first and second housing sections by the hands of the user and making each electrode contact the living body, and when said first and second housing sections are separated from each other, the living body between the separated first and second housing sections can be measured by holding each of the separated first and second housing sections by each of the hands of the user and making each electrode contact the living body;
- wherein said second current feeding electrode establishes an electric current path in the living body in relation to said first current feeding electrode, said second measurement electrode detects any potential difference induced in the living body in relation to said first measurement electrode, said measuring unit measures the impedance based on the potential difference induced in the living body between said first and second measurement electrodes, said data input unit sets the measurement condition, said arithmetic unit performs an arithmetic operation based on the data derived by said measuring unit and the data entered by said data input unit, and said display unit displays the input data and the arithmetic result.
