Intended Use

The Bair Hugger temperature management system is intended to prevent and treat hypothermia. In addition the temperature management system can be used to provide patient thermal comfort when continuations exist that may cause patients to feel too warm or too cold. The temperature management system can be used with adult and pediatric patients.

Device Story

The 3M Bair Hugger Model 675 is a forced-air warming system consisting of a portable warming unit, a flexible hose, and a warming blanket or gown. The unit uses an electrical resistance heater and a fan to deliver warmed air through the hose into the blanket/gown, which features small perforations to disperse air over the patient's skin. The system can also provide ambient (non-warmed) air. It is used in clinical settings to manage patient body temperature, preventing or treating hypothermia and providing thermal comfort. Healthcare providers operate the unit via a user control interface. The device benefits patients by maintaining normothermia during or after medical procedures.

Clinical Evidence

Bench testing only. Performance and safety were validated against IEC 80601-2-35 standards to demonstrate equivalence to the predicate device.

Technological Characteristics

Forced-air warming system; electrical resistance heater; fan/blower; flexible hose; warming blankets/gowns with air-dispersing perforations; portable unit with optional rolling cart; software-controlled; tested to IEC 80601-2-35.

Indications for Use

Indicated for adult and pediatric patients to prevent and treat hypothermia or provide thermal comfort.

Regulatory Classification

Identification

A thermal regulating system is an external system consisting of a device that is placed in contact with the patient and a temperature controller for the device. The system is used to regulate patient temperature.

Dear Brian Kleiber:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

### Description of Device:

The 3MM Bair Hugger™ Temperature Management System, Model 675 consists of a Model 675 portable warming unit (with optional rolling cart) along with a 3M Bair Hugger warming blanket or warming gown. The Bair Hugger warming unit provides forced warm air using an electrical resistance heater, fan/blower and a user control interface. Warmed air flows from the warming unit into a Bair Hugger warming blanket or warming gown by means of a flexible connecting hose. The Bair Hugger warming blanket or warming gown is placed over, around or underneath the patient. Small perforations in the blanket or gown allows the forced warm air to be gently dispersed over a patient's skin to prevent and treat hypothermia, and/or to provide patient thermal comfort. The warming unit may be controlled to provide only ambient (non-warmed) air.
