IV Fluid/Blood Warming System Description
The enFlow
IV Fluid/Blood Warming System consists of the enFlow Warmers (Model 100 series, the enFlow
Controller/AC Power Pack (Model 120 series), the enFlow AC Power Pack (Model 120 series), the enFlow
Disposable Cartridge with or without an IV Extension Set (Model 200 series). Within seconds, this Warming
System delivers normothermic infusate to the patient at flow rates of Keep Vein Open (KVO) to 200 mL/min
when input fluid temperature is 20 °C.
The Warmer is the reusable heating unit designed to work in conjunction with the Disposable Cartridge. Two
multicolored light emitting diode (LED) indicators on the Warmer indicate its power status and the fluid/blood
infusate temperature. The infusate within the Disposable Cartridge is warmed when in contact with the
heating surface of the Warmer. This surface is heated by means of electrical resistance. The Warmer
contains redundant temperature sensors to help ensure fluid temperature accuracy and reliability
.
It also
includes two independent over-heating protectors. Continuous internal diagnostics monitor essential
components and system parameters when heating fluid/blood.
The only distinction between the two versions of the Warmer, both of which are Model 100 series, is the
connector at the end of the power cord, which determines whether the unit will powered from alternating or
direct current.

The Controller/AC Power Pack serves as a power supply for the Warmer
unit. The Controller/AC Power Pack is designed to mount on an IV pole or
sit on a table top. The front panel includes a temperature display
reading in degrees C, as well as a keypad, which controls the clock and
the mute feature. Regardless of the orientation of the unit, the
temperature readout is always displayed in a “right-side-up” view.
The AC Power Pack also serves as a power source for the Warmer unit. It is
similar in design to the Controller/AC Power Pack only without the display
feature.
