3M Bair Hugger Patient Warming Unit Model 675

3M  Bair Hugger  Patient Warming Unit — Model 675

The 3M™ Bair Hugger™ Warming Unit Model 675 is an advanced, forced-air patient temperature management system designed to provide reliable, controlled, and safe perioperative and clinical warming therapy in hospitals, surgical centres, emergency departments, and critical care settings. Recognized globally in healthcare for its efficacy in maintaining normothermia and enhancing patient comfort, the Model 675 delivers consistent, precisely regulated warm air through a flexible hose to compatible warming blankets and gowns, helping prevent inadvertent hypothermia and support optimal recovery outcomes.

🚑 Core Functionality & Clinical Purpose
* Purpose: Delivers forced, warmed air to a patient to prevent and treat hypothermia, and to provide continuous thermal comfort throughout perioperative phases including pre-operative, intra-operative, and post-operative care.
* Technology: Uses an electrical resistance heater combined with a quiet internal blower that pushes air through a lightweight, detachable hose into 3M Bair Hugger™ blankets or gowns with perforations that evenly distribute heat.
* Compatibility: Works seamlessly with all 3M Bair Hugger™ disposable warming blankets and gowns (adult, pediatric, and specialty styles).

🔥 Key Performance Features
✔ Precision Temperature Control
* Multiple temperature settings (e.g., Ambient, 32 °C, 38 °C, 43 °C) allow clinicians to tailor warming intensity to patient needs, conditions, and clinical protocols.
Venture Medical
✔ Quiet and Efficient Operation
* Designed for minimal noise output (~50 dBA), ensuring a calm and controlled clinical environment while maintaining effective airflow performance (~44 CFM).
Venture Medical
✔ Compact & Versatile Mounting
* Lightweight and compact — mountable on an IV pole, wall, bedrail, rolling cart, or placed on a flat surface next to the patient — facilitating flexible placement in tight clinical spaces.
3M Malaysia
✔ Ergonomic Hose & Maintenance Alerts
* Detachable ergonomic hose articulates easily and connects securely to warming blankets/gowns.
* Integrated Filter Change Indicator signals when the MERV-rated intake filter requires replacement for optimal performance and hygiene.
Venture Medica
✔ Safety Alarms & Controls
* Built-in Over-Temperature and Under-Temperature audible/visual alarms ensure patient safety by immediately alerting clinicians when set parameters are exceeded or not reached.

⚠️ Important Symbols & Indicators
When used clinically, the Model 675 interface and manuals may employ standardized medical device symbols to communicate status, warnings, and operational conditions. These include:
🔴 Critical Alerts
🛑 Over-Temperature Alarm Indicator
Displays when internal air exceeds safe limits — clinical action required (stop therapy, check system).
⬇️ Under-Temperature Alarm Indicator
Illuminates if air output fails to reach expected setpoints — may indicate blockages or system issues.
⚠️ Safety / Maintenance Icons
🧰 Service Required Symbol
Often a wrench or tool icon on service screens indicating a need for professional maintenance.
