Thermoregulatory Sweat Test Chambers

Custom Designed Thermoregulatory Sweat Test (TST) Chambers available for purchase from DFR

Devices For Researchers, LLC

Owned and Operated by Steven Torontali

Over 30 years of creating devices out of Cleveland, Ohio for researchers and the medical community and able to design and fabricate a custom order a TST Chamber for your research needs.

DFR will work with you to understand the scope of the chamber and secure materials needed to proceed. Your TST Chamber will be designed to fit within your existing environment and available for purchase. Ongoing support and maintenace will also be provided as needed.

Located out of Cleveland, Ohio, DFR has taken on projects across the country and held meeting with scientists around the world.

Devices for Researchers has attained UL Listed certification and has passed UL's published standards for safety for a specific category of equipment.

In 1992, Devices for Researchers (DFR) invented the first modern accurate and repeatable thermoregulatory sweat testing (TST) environment to create and maintain patient perspiration for diagnosing numerous autonomic and neurological disorders that result in abnormal body temperature regulation and sweat production.

Once such TST Chamber is currently being used at The University of Alabama at Birmingham, making it the seventh comprehensive autonomic testing laboratory in the United States. The lab, the only comprehensive such facility in the Southeast, can assist physicians in the diagnosis of conditions associated with autonomic function, including disorders of the peripheral nervous system such as painful small fiber neuropathies, diabetic autonomic neuropathy and neuropathies associated with connective tissue disorders. It is also useful for some central nervous system disorders including parkinsonian syndromes like multiple system dystrophy and Lewy body dementia. It also has utility in diagnosing complex regional pain syndrome. The video below explains how they are using the TST Chamber.

Listen here to the UAB Medcast podcast of Mohammed Kazamel, MD as he discusses how the sweat function is an indicator of the whole nervous system and how the TST Chamber is a useful tool to measure it.

Unique Innovative Method

Since its invention, multiple chambers throughout the country have been built and installed in Medical Schools and Hospitals. Our TST chambers are a time-proven method that retains perspiration as it is created. This is achieved by precisely controlling temperature and humidity within 1 setpoint. The TST chamber uses two options for thermoregulatory sweat. First is heat and humidity. Second is humidity and infrared heat to generate perspiration. Infrared utilizes 5 optimally placed infrared lamps that are controlled by six skin sensors that monitor and display in real-time the temperature of the legs, arms, torso, and head. The combined temperatures are used to accurately control the infrared lamps precisely to 1-degree Centigrade, preventing overshooting and skin injury.

Ease of Use

The TST Chamber is fully automated with a one button operation. The control panel is easy to operate and provides in real time temperature and humidity readings. The panel allows complete control of the chamber environment and incorporates backup safety features.

Outstanding Patient Comfort

There are two options for placing the patient into the chamber: side entrance of a patient on a gurney and a vertical sliding door entrance with a patented detachable patient tilt table for orthostasis maneuvers.

The unique design allows for an unobstructed observation and communication between

the patient and the technician.

Compact and Clean Design

The footprint of this design allows for it to be installed without taking up significant space and side door entrance allows easy access.

Real-Time Images and Recording

An HD camera with a specialized wide distortion-free lens views and records the patient during testing. You are able to capture thermal and video images at any time and store them for patient diagnosis and documentation.

Durable and Reliable

All components are heavy duty industrial grade. The first 1992 TST Chamber is still in use today and requires minimal maintenance.
