System Overview

The Indus Rodent Surgical Monitor is an advanced, integrated surgical warming and vital signs monitoring solution for preclinical research in mice, rats and other small animals. The system provides detailed information, in real time, regarding subject body temperature, ECG, heart rate, pressure and respiration. The system incorporates intelligent zone heating, ultra-low noise, high-resolution ECG electronics, noninvasive electrodes, and a port for external needle electrodes for when subjects cannot be laid prone or supine.

Standard setup consists of three components:

  • Touchscreen Display Unit
  • Heated Surgical Platform  
  • Temperature Probe

Optional components:

  • Pulse Oximetry Thigh Clip
  • Pressure Adapter Cable and Pressure Catheter
  • External Needle Electrodes
Temperature
IndusInstruments_BT_icon1-200x200

Core body temperature is measured by rectal probe and regulated via the Heated Surgical Platform.

ECG
IndusInstruments_ECG_icon1-200x200 - Copy

High-resolution multi-lead ECG measured by noninvasive paw or subcutaneous needle electrodes.

Heart Rate
IndusInstruments_Activity_Icon1-200x200

Heart rates between 60 – 999 bpm are automatically calculated from the R peaks of the ECG signal.

Respiration
IndusInstruments_Resp_icon1-200x200

Properly titrate anesthesia based on respiration rate, measured using electrical impedance.

Pressure
IndusInstruments_HR_icon1-200x200 - Copy

Measure high fidelity arterial and ventricle pressure in mice and rats using a solid state pressure catheter.

SPO2

Measure arterial blood oxygenation non-invasively in mice and rats using a thigh clip sensor.

Features & Benefits

Real Time Monitoring

Clearly labelled numeric panels and measurement waveforms make it easy to monitor critical parameters.

Versatile

Three sets of electrodes make it easy to work with small mice, large rats and many small animals in between.

Ultra-Low Signal Noise

Enhanced design minimizes interference for clean, accurate physiological data you can trust.

Easy Documentation

A single image can capture animal ID, vital signs, study ID, researcher, date, time and all filter settings.

Standalone Data Collection

Capture data, make comments and view recordings on the tablet to quickly take measurements and verify experiment details.

Electrically Isolated Bio-Amplifiers

Prevents cross-talk and artifact distortion, enabling clear, high-fidelity signal acquisition.

Seamless Data Export

effortlessly integrates with third-party software for advanced analytics and streamlined workflows.

Customizable Presets

Define optimal study conditions and ensure consistency between subjects and collaborating labs.

Flexible

Expansion modules allow you to easily add functionality later as your lab and study’s needs change.

Consistent Thermal Regulation

Built-in heating ensures temperature stability for your experimental animals, boosting reproducibility.

Electrically Isolated Bio-Amplifiers

Prevents cross-talk and artifact distortion, enabling clear, high-fidelity signal acquisition.

Temperature Probe

Each Rodent Surgical Monitoris delivered with a single rectal temperature probe. Customers may select between probes optimized for neonatal mice, adult mice, or rats.

The temperature probe sensor is a Copper-Constantan Thermocouple, located at the tip of the probe. Probe temperature and accuracy is  +/-0.1°C. 

RSM oX Model

Additional Oxygen Saturation Capabilities

  • Patent-Pending Technology – Integrated PulseOx sensors built directly onto the platform via the embedded stainless-steel electrode
  • Reduce Noise and Variability – No longer worry about poor sensor placement, fur interfering with measurement, noise from respiration or cable movement
  • Optimal and Stable Measurement – Reproducibly measure from a consistent site.
