Investigational Device — Intraoperative Warming

Maintain Core
Temperature. Save Lives.

Intraoperative hypothermia affects 1 in 3 surgical patients. THöRML delivers precise, continuous warmth through a next-generation warming blanket engineered for the demands of the modern OR.

Hypothermia is a
Preventable Complication

Even a 1–2°C drop in core body temperature during surgery increases the risk of surgical site infections, adverse cardiac events, and prolonged recovery. Existing forced-air warming solutions are bulky, inconsistent, and disruptive to the sterile field.



THöRML was engineered from the ground up to solve what forced-air blankets cannot: uniform contact warming with minimal airflow contamination risk.

Closed-Loop Temperature Control

An integrated sensor array feeds real-time temperature data to the controller unit, which auto-adjusts power delivery to maintain the clinician's target temperature.

Minimal External Airflow

Unlike forced-air warming blankets, THöRML is designed to produce minimal external airflow, minimizing risk of airborne particulate dispersion into the surgical field — critical for implant and orthopedic procedures.

Single-Use Packaging

Each THöRML blanket ships individually in a sealed package and is designed for single-patient use — simplifying infection control protocols and eliminating decontamination overhead.

Modular Sizing System

Available in pediatric, adult-upper body, and full-body configurations. A universal controller unit pairs with any blanket size, reducing capital expenditure across your OR suite.

Clinical Evidence

Built on Peer-Reviewed
Clinical Science

THöRML's design and efficacy claims are grounded in published literature on intraoperative normothermia and patient outcomes.

Risk of surgical site infection increases threefold in patients experiencing intraoperative hypothermia versus those maintained at normothermia throughout the procedure.

Clinical Workflow

In the OR in Four Steps

01
Unpack & Position

Remove THöRML from its individually packaged sleeve and position under or over the patient according to the procedure type. No pre-warming required.

02
Connect Controller

Plug the blanket's connector into the bedside controller unit. The system self-tests and confirms connection readiness in under 10 seconds.

03
Set Target Temp

The circulating nurse dials the target temperature on the controller. Closed-loop feedback begins maintaining the set point automatically for the duration of the procedure.

04
Dispose & Document

After the procedure, discard the single-use blanket and hose if desired. Total teardown time: under 60 seconds.
