Covidien Somanetics 5100C-PB System Preamplifier B Module Channels 3 & 4

Covidien INVOS™ 5100C Preamplifier Module B | Channels 3 & 4 | 5100C-PB

The Covidien Somanetics 5100C-PB is a critical expansion component for the INVOS™ 5100C Cerebral/Somatic Oximeter. While the standard INVOS™ setup typically monitors two sites, the addition of the 5100C-PB Module B enables Channels 3 and 4, allowing for a comprehensive four-sensor configuration. This is essential for simultaneous bilateral cerebral monitoring alongside somatic (renal or mesenteric) site tracking, providing a "whole-body" view of tissue perfusion.

By placing the preamplification hardware closer to the patient, the 5100C-PB minimizes electronic interference and signal degradation over long cable runs. This ensures that the low-amplitude light signals returning from the patient's tissue are accurately digitized and transmitted to the 5100C monitor for real-time saturation analysis.

Key Specifications

• Manufacturer: Covidien / Somanetics (Medtronic)

• Model / REF: 5100C-PB

• Role: Preamplifier Module B (Expansion)

• Channel Support: Channels 3 and 4

• System Compatibility: INVOS™ 5100C Regional Oximetry System

• Technology: Near-Infrared Spectroscopy (NIRS)

• Cleaning: Surface Wipe-Down Compatible (Medical Grade Disinfectants)

Technical & Clinical Advantages

• Four-Channel Monitoring Capability: Enables clinicians to monitor multiple physiological sites simultaneously (e.g., Left/Right Cerebral and Renal/Somatic). This is vital in cardiac surgery and neonatal ICU settings to detect regional desaturation before systemic markers change.

• Low-Noise Signal Preamplification: The 5100C-PB isolates and amplifies the delicate NIRS signal at the source. This high-fidelity processing is crucial for maintaining accuracy in electrically "noisy" environments like the Operating Room or Cath Lab.

• Seamless INVOS™ Integration: Specifically keyed for the "Module B" port on the 5100C monitor, this unit allows for "plug-and-play" expansion without the need for complex software reconfiguration.

• Durable Medical-Grade Housing: Constructed to withstand the rigors of continuous bedside monitoring, the module features a robust casing and reinforced cable strain reliefs to prevent signal loss during patient transport or repositioning.

• Proprietary Sensor Interface: Designed to work exclusively with INVOS™ SomaSensor™ technology, ensuring that the calibration and light-source wavelengths remain within strict clinical tolerances for $rSO_2$ measurement.

Applications

• Cardiac & Vascular Surgery: Monitoring for cerebral desaturation during cardiopulmonary bypass or carotid endarterectomy.

• Neonatal & Pediatric ICU: Tracking somatic perfusion (renal/gut) to assist in the early detection of Necrotizing Enterocolitis (NEC) or acute kidney injury.

• Critical Care: Long-term trending of regional oxygenation in patients with traumatic brain injury (TBI) or septic shock.

• System Maintenance: Serving as a direct OEM replacement for damaged preamplifiers in existing four-channel INVOS™ fleets.

Condition & Quality Assurance

• Status: Used – Excellent Physical Condition.

• Source: This module has been carefully extracted from a retired, fully functional INVOS™ 5100C system.

• Maintenance: The housing is intact, and all connector pins are straight and free of oxidation. While it shows normal signs of prior clinical use (minor surface scuffs), it has been handled with professional care to preserve internal circuitry.

• Professional Standards: With over 25 years of experience in medical electronics and hospital materials, Primis Medical ensures all specialized monitoring components are visually inspected and safely processed prior to shipment.

Shipping & Handling

• Secure Logistics: Shipped in anti-static, padded packaging to protect the sensitive internal preamplification circuitry from electrostatic discharge (ESD) and impact during transit.

• Fast Dispatch: Ships within 1 business day.
