{4}------------------------------------------------

The Microheater warms intra-venous fluids, including blood and blood products, to physiological temperature, and monitors fluid temperature. It also senses lack of IV fluid flow, or empty cartridge, and a number of internal fault conditions including over-heating, loss of electrical connection to the heater, and failure to heat. The device stops heating and alarms if an alarm or fault condition occurs. The system provides the user with alarm, alarm message, temperature, and other operating information via a bright alphanumeric display.

The sterile disposable set is placed in-line between a standard IV line at its input and a user-supplied cannula or IV infusion set at its output. The input can come from a gravity fed IV line with roller clamp and drip chamber, external to the device and not supplied by Belmont Instrument Corp. The Microheater is not meant to be used with pressurized infusers.

The device is intended for low applications where the flow rate is 6 liter/hour (100 ml/min) or less.

- 9. Intended Use: The Microheater intended use is for warming blood, blood products and intravenous solution prior to administration. It is intended to be used by healthcare professionals in clinical environments to prevent hypothermia. The system is not meant for the infusion of drugs, or platelet or granulocyte suspensions.
## 10. Summary of the technological characteristics of the Belmont Microheater:

The heater unit is powered with 15 V pulsed DC which is derived from 120 or 230 VAC, 47 - 63 Hz AC/DC Converter. The temperature of the infused fluids, visual and audible alarms, and other performance characteristics of the heater unit are controlled electronically. The disposable set consists of a molded frame to which a plastic film is bonded to one side and a microporous membrane is bonded to the other to form the fluid path. The disposable set has a sterile, non-pyrogenic fluid path, and is for single-patient use only.

## 11. Summary of Nonclinical Tests and Results

In order to verify performance of the Belmont Microheater in support of substantial equivalence, the following tests were carried out:

- Verify the ability of the system to warm cold fluids to physiological a. temperature.
- b. Verify the ability of the system to detect and alarm at unsafe or ineffective operating conditions.

- 12. Conclusion: The Belmont Microheater Blood/Fluid Warmer is substantially equivalent to the Estill Medical Technologies, Inc. Thermal Angel™ Blood/Fluid Warmer which received 510(k) approval on July 1, 1999. Both systems have the same intended use, and are capable of heating blood products or intravenous fluids prior to administration to physiological temperature. Both systems have an independent fail-safe circuit which stops heating and alarms if the system overheats
