Applications:
MMS® proprietary technology is unique in its ability to measure temperature of in-line blood and fluid and, with this knowledge, is able to manipulate in-line blood and fluid temperatures with unmatched responsiveness, control and safety.
The initial system developed by MMS, and which remains in clinical use today, was the MMS® ThermoStat ™900 In-Line Fluid and Blood Warmer. The ThermoStat™ 900 was developed with support from the U.S. Army, and the National Institutes of Health (“NIH”), and was clinically evaluated at Tufts New England Medical Center (“NEMC”). This first-of-its-kind system combines microwave power generation with radiometric sensing to accurately measure temperature, and rapidly and safely heat and/or infuse blood and fluids. The MMS® TM900™ also maintains a normothermic outlet temperature, measures fluid flow rate, and detects air emboli.
The ThermoStat™900 has been designed with technical features that conventional fluid and blood warmers and infusers cannot provide, for a cost that is highly competitive. The features include low priming volume, measurement of flow rate, integrated detection of air emboli, and the measurement of actual fluid temperature (not the temperature of the water or heater plate, as in other systems).
Conventional water-bath fluid and blood warmers require turbulence/mixing to achieve efficient heat transfer from the walls or surface of the disposable. Turbulence is known to damage blood and create air bubbles, and should be avoided. Unlike conventional warming systems, MMS®’ patented, in-line warming technique does not require turbulence. Plastic IV tubing is transparent at microwave frequencies, and the walls of the tubing are not heated.
Heating the IV fluid/blood, as well as the radiometric temperature sensing is in-line, direct, and instantaneous.
A risk associated with the use of conventional warm water baths is infection from the water, which is known to harbor bacteria. The risk of infection is compounded by the need for very fragile, thin-walled tubing (the heat exchanger) in order to heat the fluid within the tubing.
The ThermoStat™900 is a dry system that uses a small disposable cartridge with a short length of standard IV tubing. MMS®’ microwave approach does not require a thin-wall disposable. The continuous in-line tubing path prevents the formation of boluses of trapped air with minimal, if any, turbulence. The total volume of fluid contained within the microwave heating cavity is very small -- only 2ml.
In commercial use today in hospitals and trauma centers in the U.S., this FDA-cleared system is designed to maintain a normothermic outlet temperature in a wide range of inlet-temperatures and flow rates. Whereas Conventional warmers are inadequate at high flow rates, MMS®’ ThermoStat™ 900 operates efficiently at both high or low flow rates. For further information, please contact info@mms-llc.com.
