Medical Research ISX-3

FAST. PRECISE. PATIENT-SAFE.

You want to use impedance spectroscopy in a medical research application? You like it simple, precise and fast and you don't want to worry about patient safety? Then check out the Medical Research ISX-3 impedance analyzer.

It bases on our ISX-3 impedance analyzer. It is equipped with Sciospec’s IF frontend with 4-port BNC interface supporting simple 2 point measurements, as well as 3 and 4 electrode configurations. Within the measurement range from 100 mHz to 10 MHz (extendable to 40 or 100 MHz) it covers a dynamic range of 300dB (mOhm…TOhm) with a base precision of 0.01%.

Additionally the Medical Research ISX-3 includes measures for enhanced electrical safety including medical grade isolation enabling a safe operation of the instrument in medical research settings.

Application brief
IMPEDANCE MEASUREMENT OF A FOREARM

The ISX-3 impedance analyzer is not a medical product and as such its intended purpose does not include diagnosis and/or treatment of patients. But the Medical Research ISX-3 includes several added safety measures specified in accordance with DIN EN 60601-1:2013-12 "Medical electrical equipment – Part 1: General requirements for basic safety and essential performance". These measures ease the application for excemptions for experiments on patients.

Medical grade safety features

Enclosure: prevention of contact between electrical circuitry and external equipment or humans, shielding of measurement frontend (noise reduction) and mechanical safety
Medical grade power supply: external isolated AC/DC converter supplies device with 12 V DC, additionally stand alone battery operation is possible including software controllable electromechanical switch-off for DC input lines
Isolated Full speed USB interface: fullspeed USB port for instrument control and data readout from PC
Ethernet interface: standard RJ45 Ethernet interface for remote control of the instrument
- The interface is not internally isolated. An external medical grade network isolator (included in the offer) can be inserted in the communication path to ensure safe isolation ratings.
IsoIO module: low level communication interfaces including hardware synchronisation and flexible programmable IO standards including serial (UART, SPI, I2C) for use of the instrument with other external equipment
Measurement and control modules: core functionality of the impedance analyzer including measurement control, signal processing, excitation generation and analog measurement functions
AC coupling frontend: External module for AC coupling of measurements ports. Blocks DC currents and adds a high pass filter characterisitic limiting low frequency currents. Isolates the instrument galvanically from the measurement object or patient interface.
