### Device Name

Proprietary name: ChillBuster™ Portable Electric Blanket Common name: Hypothermic Therapy System. CDRH Product Regulation: Thermal Regulation System (21 CFR, 870,5900)

### Establishment Registration Number: 1043582 (Microtek Medical, Inc.)

## Classification: II (74 DWJ)

## Statement of Substantial Equivalence

ChillBuster™ Portable Electric Blanket is equivalent to:

- 1. ChillBuster™ (ThermoGear K991684)
- 2. Life-Air 1000 (Progressive Dynamics Inc., Marshall, MI)

#### Description of Device

The ChillBuster™ Portable Electric Blanket System is made up of six major components:

Blanket. The main functional system element is 40"X 60" in area, featuring an oxford nylon outer layer and an inner layer of knapped acrylic blanket fabric. The unique ChillBuster™ array of special thermal wire resides between the two layers, thermal wire extensions and electrical data relative to blanket temperature exiting the blanket through a special interface and connector at one blanket corner. The latter blanket connector extends a few inches from the blanket corner, and mates with the blanket cable from the control module. The blanket can be machine washed and dried.

Control Module. Five key sub-units form this component: 1) one electric circuit board (ECB) where all control and electronics reside; 2) one user interface panel, providing information and controls; 3) Interconnect wiring to the user interface panel and to the battery; 4) a molded chassis that forms the base for the other components, along with a recessed compartment accepting two sizes of battery (see below); and 5) the blanket cable, hard wired to the ECB, and exiting the control module through the user interface panel (see cabling below);

{1}------------------------------------------------

Cabling. There are two cables associated with the system. One is the blanket cable, hard wired to the ECB, exiting the control module through the interface panel, and extending approximately six feet to a terminal connector at the blanket end of the cable. The latter connector mates with a corresponding connector that terminates a short (few inches long) pigtail cable protruding from the corner of the blanket. The other cable is an optional cigarette lighter cable, to allow system charging and/or operation using power from any vehicle cigarette lighter socket that supplies 12 volts;

3)

Battery. The 8000 series employs a 12 volt, sealed lead acid, rechargeable battery. The control module will accept two different battery configurations, of 7 amp-hour and 4 amp-hour capacity, respectively. The purchaser specifies the desired battery capacity at the time of purchase.

AC adapter. All 8000 series systems include and standard, U2601-1 approved, AC-to-DC adapter properly matched to the voltage, current and interconnect requirements of other system components applicable to local AC line power.

Carrying Bag. ChillBuster™ systems include a custom carrying bag with several important features, including; a suitcase type carrying handle; a shoulder strap; and an internal shelf in the bag that separates the upper two thirds of the bag cavity as a blanket and cable storage compartment, leaving the lower one-third for the control module with attached battery. Removal of the blanket and cables from the carrying bag permits user access to the user interface panel on the control module.

Standards. The following standards were used in the testing of this unit:

General Medical Safety: IEC 601-1: 1998; Amd. 1: 1991; Amd. 2: 1995 UL 2601-1

EMC IEC 601-1-2

#### Intended Use

To reduce the effects of hypothermia encountered during the trauma of a surgical procedure or other medical crisis which could result in the onset of a hypothermic condition.

Dear Mr. Bonner:

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. 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.

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