EIS system features
Successive measurements are performed with weak DC current
and then very low frequency (from 100 Hz to 700 Hz) between six tactile electrodes placed symmetrically on the left and right
forehead, palm of hands, and sole of the feet of the subject.
Each electrode is alternatively cathode then anode (bipolar
mode), which permits the recording of the conductivity (Ohm‘s Law) of 11 interstitial fluid pathways of the human body.
The hand and foot electrodes are large size at least 250 cm2 and in metal
The forehead electrodes are disposable (single
use) and in Ag/Ag/Cl.
The device provides
for each pathway:
- The conductivity from
anode to cathode (SDC+)
- The conductivity
from cathode to anode (SDC-)
- The delta
between SDC+ minus SDC –, in numeric value and scale from 0 to 100
- The dispersion of the current in pathway expressed in conventional unit (coefficient α).
Indications for use:
EIS (Electro Interstitial Scan) is a medical device for
the measurement of galvanic skin response
Intended
uses according to the features
Estimation of parameters related to living tissue:
- Estimation of the tissue O2 consumption
- Estimation of the interstitial fluid negative ions density
( Chloride ions and bicarbonate)
- Estimation
of the interstitial fluid balance positive ions – negative ions related to the Chloride ions density.
- Estimation of the morphology of the interstitial fluid
space.
According
to the clinical investigations
- Follow ups of drugs’ administration (thyroid hormone, beta blockers, ACE inhibitors and
SSRI treatments)
- Screening of the prostate
cancer and ADHD children ( learning disorders)
- Estimation
of the sympathetic system modulation.
The
EIS will be used for children (over 5 years old) and adult patients.
The device is not a diagnostic tool and not intended
for use in support life and not for continuously monitoring.
The system should be used by a practitioner.
