The SOZO Pro has the following uses:
For adult human patients at risk of lymphedema:
A bioimpedance spectroscopy device for use on adult human patients, utilizing impedance ratios that are displayed as an L-Dex ratio that supports the measurement of extracellular volume differences between the limbs and is presented to the clinician on an L-Dex scale as an aid to their clinical assessment of lymphedema.
The use of the device to obtain an L-Dex score is only indicated for patients who will have or who have had lymph nodes, from the axillary and/or pelvic regions, either removed, damaged or imadiated.
Device Description
The SOZO Pro system consists of a connected hand and footplate with built-in stainless-steel electrodes, paired with an Android tablet over Bluetooth connection. An app ("SOZOapp"), supplied with the tablet, controls the functionality of the hardware, and supplies the bioimpedance measurement data to a database ("MySOZO") managed on an external cloud- hosted database. Patient weight is measured with load cells located in the SOZO Pro foot unit or can be hand entered.
Bioimpedance measurements require the patient's weight to be measured by a scale embedded in the base of the system or for the weight of the patient to be entered manually. Following the collection of the patient weight, the patient contacts the SOZO Pro with their bare hands and feet on stainless steel electrodes. The impedance measurement takes about 30 seconds, during which the SOZO Pro® system applies small levels of electrical energy (200µA RMS) to the body across 256 frequencies spaced from 3kHz to 1000kHz and measures the resulting voltage levels.

Intended Use
MoistureMeterD Compact and LymphScanner is a device utilizing inter-am ratios of tissue dielectric constant (TDC) that supports local assessment of tissue water differences between affected and contralateral non-affected ann tissues to aid in forming a clinical judgment of unilateral lymphedema in adult women. The device is not intended to make a dagnosis or predict arm lymphedema.
Device Description
The MoistureMeterD Compact (MMDC) and the LymphScanner are identical differently labelled bioelectrical analyzers to measure localized tissue fluid content. High-frequency electromagnetic waves produced in the hand-held main unit are guided into integrated open-ended coaxial probe. When the probe is placed onto the skin, skin and upper subcutis is exposed to electromagnetic field. In skin and upper subcutis electromagnetic fields are interacting with tissue water molecules by rotation causing absorption of electromagnetic energy in tissue. The devices measure the amplitude and phase shift of the reflected electromagnetic wave and calculate tissue dielectric constant (TDC). Tissue dielectric constant (TDC) is an index of localized tissue water content. The measured TDC value can be converted into Percentage Water Content (PWC) value.

The SOZO system consists of a connected hand and footplate with built-in stainless steel electrodes, paired with an Android tablet over Bluetooth connection. An app ("SOZOapp"), supplied with the tablet, controls the functionality of the hardware and supplies the bioimpedance measurement data to a database ("SOZOhub") contained within the hospital/facility network.
Measurements require the patient to make contact with bare hands and feet on stainless steel electrodes. The measurement takes about 30 seconds, during which the SOZO™ system applies small levels of electrical energy (200µA RMS) to the body across 256 frequencies spaced logarithmically from 3kHz to 1000kHz and measures the resulting voltage levels. Established algorithms are used to analyze data and calculate extracellular fluid impedance levels for left and right limbs, and present the impedance ratio as an L-Dex® score for the clinician to review. This score facilitates their clinical assessment of lymphedema in adult human patients.

Lymphedema Analysis PC Software - an optional PC software package that is intended to be used only with the ImpediMed L-Dex U400 device for uploading data on to the PC from the L-Dex U400, processing and analyzing of bioimpedance measurements.
Device Description
The ImpediMed L-Dex U400 Extra Cellular Fluid Analysis device is a battery powered bioimpedance spectroscopy device operating in tetra-polar mode via a set of leads that are attached to self-adhesive skin electrodes by means of alligator clips. The subject device accurately measures current, voltage and phase angle, and cakulates three bioimpedance parameters: impedance (Z), resistance (R) and reactance (Xc). These measurements and calculations are used to estimate extracellular fluid ratios, and calculate the Lymphedema Index or L-Dex.
The L-Dex U400 measures bioimpedance parameters over a frequency range of 4 - 1000 kHz with 256 data points. An on-screen graph displays the raw measured data in the form of a resistance vs. reactance complex impedance plot. These bioelectrical parameters are then used in algorithms to give an L-Dex value for the affected compared to the unaffected limb.
Measured impedance ratios (L-Dex values) and normal ranges are shown on the device immediately after measurement and stored for later reference. Measured data may be transferred to the ImpediMed Impsoft database software. The Impsoft software adds extra functionality and ease of data management, including viewing patient histories and printing reports.
