Covidien 313363 INVOS Cerebral/Somatic Oximetry Preamp (Channel 3/4) – Rev L

The Covidien 313363 is a high-fidelity modular preamplifier designed to expand the monitoring capabilities of the INVOS™ 5100C (and compatible) Cerebral/Somatic Oximetry systems. This "Preamp B" module provides the necessary signal conditioning and low-noise amplification for channels 3 and 4, allowing clinicians to monitor regional oxygen saturation ($rSO_2$) at up to four anatomical sites simultaneously.

The Revision L (Rev L) designation ensures this unit meets updated manufacturing tolerances for stability and signal-to-noise ratio. Because NIRS technology relies on detecting minute changes in light absorption to differentiate between superficial and deep tissue oxygenation, the 313363 is engineered to protect signal integrity from the sensor to the monitor, providing the accurate data needed for critical hemodynamic decision-making.

Key Features

• Manufacturer: Covidien (Medtronic)

• Model Number: 313363

• Revision: L

• Function: Expansion module for Channels 3 and 4.

• Compatibility: Designed for use with INVOS Cerebral/Somatic Oximetry monitors.

• Technology: NIRS (Near-Infrared Spectroscopy) signal processing.

Clinical & Operational Advantages

• 4-Channel Capability: Enables comprehensive "Whole-Body" monitoring by adding somatic channels (e.g., renal or mesenteric) alongside bilateral cerebral readings—essential for neonatal and cardiac surgery.

• Plug-and-Play Scalability: Allows facilities to upgrade their existing 2-channel INVOS units to 4-channel capacity without purchasing a new base monitor.

• Low-Noise Processing: Rev L architecture is optimized for high-fidelity amplification, ensuring that deep-tissue signals are isolated from extracerebral interference.

• Integrated Cable Management: Designed to dock securely with the INVOS system, providing a clean and organized cable path from the patient to the monitor.

Condition

• Status: Used – Functional Condition.

• Functional Status: This unit was removed from a working clinical environment. The connection ports are clean, and the internal housing is secure.

• Cosmetic Status: Shows visible signs of normal clinical use, including minor surface scuffs or slight discoloration of the plastic housing.

• Testing Note: As a modular electronic component, it is recommended that this unit be verified by your facility's biomedical engineering department upon integration into your INVOS system.

Warranty

• ✔ Primis "Signal Lock" Guarantee

  We guarantee the Covidien 313363 to be fully functional. If the preamp fails to communicate with your INVOS monitor or produces "no signal" on channels 3/4 upon arrival, Primis Medical will provide a full refund or replacement.
