Masimo 4053 RED SET TCI Adult Reusable Ear Sensor 3' (0.9 m) SpO₂ Probe
Masimo 4053 RED SET® TCI Adult Reusable Ear Sensor – 3ft (0.9m)
The Masimo 4053 is a specialized, reusable pulse oximetry sensor designed for adult patients who require consistent SPO2 monitoring when peripheral sites (fingers/toes) are unavailable or unreliable. As part of the RED SET® TCI series, this sensor is engineered to provide superior signal capture in challenging clinical conditions, including patients with low perfusion or those undergoing cardiovascular procedures.
The ear-clip design offers an alternative monitoring site that is less susceptible to the vasoconstriction often seen in the extremities. Measuring 3 feet (0.9 meters), this sensor features a lightweight, ergonomic clip that ensures a secure yet comfortable fit on the ear lobe or pinna, providing a high-fidelity signal for Masimo-powered pulse oximetry systems.
Key Features
-
Manufacturer: Masimo
-
Model Number: 4053 (RED SET TCI-3)
-
Sensor Type: Reusable Ear Sensor (Adult)
-
Cable Length: 3 feet (0.9 meters)
-
Technology: RED SET® TCI (Trauma, Critical care, and Isolation)
-
Compatibility: Designed for use with Masimo RED SET patient cables and monitors.
-
Durability: High-quality medical-grade materials designed for repeated cleaning and long-term clinical use.
Clinical Advantages
-
Reliable Low Perfusion Monitoring: The ear is an ideal central monitoring site that maintains blood flow longer than the fingers during clinical shock or hypothermia, ensuring continuous SPO2 data.
-
Reduced Motion Artifact: Because the head is typically more stable than the hands, the ear sensor is less prone to "false alarms" caused by patient movement.
-
Comfort & Integrity: The gentle spring-tension clip minimizes pressure necrosis risk while maintaining the optical alignment necessary for accurate oxygen saturation and pulse rate readings.
-
Cost-Effective: As a reusable probe, the 4053 reduces the "per-patient" cost associated with disposable sensors in long-term monitoring environments.
Condition
-
New & Unused: This probe is in its original, unopened manufacturer’s packaging.
-
Integrity: Guaranteed to be an authentic Masimo OEM product, ready for immediate integration into your patient monitoring workflow.
-
Storage: Cleanly stored in a climate-controlled facility to preserve the silicone and electrical components.
Warranty
-
✔ Primis Medical Guarantee
This Masimo sensor is guaranteed to arrive in new, functional condition. If the probe fails to provide a reading or is incompatible with your RED SET system upon arrival, Primis Medical will provide a full refund or replacement.
Applications
The Masimo 4053 is a vital tool for:
-
ICU & Critical Care: Monitoring hemodynamically unstable patients.
-
Operating Rooms: Ideal for cases where the hands are tucked or inaccessible.
-
Emergency Medicine: Fast SPO2 assessment in trauma or cold-exposure cases.
-
Sleep Labs: A stable alternative for overnight oxygen saturation studies.
What’s Included
-
(1) Masimo 4053 RED SET TCI Adult Reusable Ear Sensor (3ft)
Shipping
-
Fast and secure shipping
-
Ships within 1-2 business days
-
Carefully packaged to ensure the precision optical components of the ear clip remain aligned during transit.
