Safe, simple and effective, Allon enables clinicians to consistently maintain patient body temperature throughout all stages of the perioperative continuum. This non-invasive, temperature management system helps surgical teams achieve more predictable outcomes. Allon’s algorithm-driven heat pump supplies heated water through a closed-loop system to the ThermoWrap® disposable patient garment. Core and surface temperature sensors provide continuous patient temperature feedback to enable thermal monitoring and regulation.

Allon is helping improve clinical outcomes in these areas

ThermoWrap for Advanced Patient Warming

Available in a range of sizes and configurations to accommodate your clinical needs and patient’s anatomy, ThermoWrap’s flexible designs facilitate the wrapping of individual parts of the body to maximize surface coverage without interfering with surgical sites. A single-use, one-piece adjustable garment, the ThermoWrap can cover up to 85% body surface area. ThermoWrap’s pressure relief algorithm and channels provide periodic pressure relief to help redistribute pressure on the patient throughout use. Featuring comfortable soft mesh, ThermoWrap is easy to wrap and secure via pressure-sensitive adhesive strips that adhere to the garment, not the patient.

Your Patient’s Fast-Track to the PACU<sup>1,2</sup>

Maintain normothermia confidently – even during long procedures. Choose your set point, then let Allon automatically regulate temperature.

Surgical Access Where Needed

Warm with ease no matter the position with ThermoWrap, which keeps the patient warm and the staff comfortable, unlike forced air warming systems.

Real Time Monitoring

Track progress real time on a color, touchscreen monitor with graphical display of temperature measurements. Post-op, access data with CliniLogger™.

Other Features

Clinician Friendly

Staying in place and out of the way with minimal noise, ThermoWrap lets the surgical team focus on the patient.

Serving the Needs of Patients

ThermoWrap maintains temperature during surgery – even in your youngest and oldest patients and longest procedures.

Responsive, Microprocessor-Controlled System

The patient’s core temperature is read every 133 milliseconds to allow for automatic adjustments of the system in order to maintain the physician-determined pre-set temperature.
