enFlow® IV Fluid/Blood Warming System Description The enFlow IV Fluid/Blood Warming System consists of the enFlow Warmer (Product No. 980100), the enFlow Controller (Product No. 980121), the enFlow Disposable Cartridge (Product No. 980200), and the enFlow Disposable Cartridge with IV Extension Set (Product No. 980202). 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 ensuring 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 Controller serves as a power supply for the Warmer unit. The Controller is designed to mount on an IV pole or sit on a table top. The front panel includes a Controller reading in degrees Celsius, as well as a keypad, which controls the clock and the mute feature. The Controller display is always shown “right-side-up”. Each Disposable Cartridge and the Disposable Cartridge with IV extension set are radiation sterilized and non-pyrogenic as well as latex and DEHP free. The Disposable Cartridge connects to the IV Extension Set or any infusion set employing standard luer connectors. Once primed, the Disposable Cartridge in conjunction with the Warmer and the Controller combine to complete the enFlow IV Fluid/Blood Warming System.

Indication for Use The enFlow IV Fluid/Blood Warming System’s intended use is for warming blood, blood products and intravenous solutions prior to administration. It is designed to be used by healthcare professionals in hospital, clinical and field environments to help prevent hypothermia.

Clinical and Training Information Operators must be trained to set up and deliver blood/ IV solutions in a medically approved manner, including aseptic techniques and standard hospital procedures. Use of the enFlow IV Fluid/Blood Warming System, properly administered, will help prevent hypothermia and the complications arising there of. This device will also help make the patient more comfortable during IV infusions, reducing shivering.

WARNINGS 



       

All IV fluid bags must be vented of air per IV fluid manufacturers’ directions prior to connecting to the infusion set. Standard IV line protocols for priming the complete infusion set, the enFlow Disposable Cartridge, and the extension set must be followed before connecting to a patient. Care must be taken to ensure there is not sufficient air in the fluid bag and lines to cause an air embolism. A flashing RED LED, a flashing RED Controller display, and an audible alarm, indicate that the infusate is over temperature. Stop the fluid flow, and slide the Warmer covers open to stop warming. This condition is not standard and should not be experienced. If it occurs, replace the Warmer and contact Technical Support. The Warmer contains magnets; do not operate within 15 cm (6 in.) of a pacemaker or other devices that may be sensitive to strong magnetic fields. The Disposable Cartridge may be a potential biohazard during or after use. Handle and dispose of in accordance with acceptable medical practice and applicable regulations. Do not use in the presence of flammable anesthetics. Replace the fuses with only Bussmann part # GDB 5A or equivalent. The Disposable Cartridge should not be used for greater than 24 hours. Ensure that the Disposable Cartridge expiration date has not passed. If the IV line runs dry, disconnect the Disposable Cartridge from the Warmer. Re-prime the entire IV system using aseptic techniques. Ensure all the air is removed from both the line and the Disposable Cartridge. Replace the Disposable Cartridge in the Warmer. The enFlow Warmer is to be used only with approved enFlow power sources and the enFlow Disposable Cartridge.

Cautions            

Follow the AABB "Guidelines for the Use of Blood Warming Devices" (© 2006) which caution against warming when administering platelets, cryoprecipitate, or granulocyte suspensions. Some drugs or drug preparations may be sensitive to warming. As with any fluid or blood warming system, carefully review the drug manufacturer's literature for information about thermal sensitivity. The Warmer heating surface and Disposable Cartridge can get quite warm when heating cold IV fluids/blood at high flow rates. Wait a few seconds after stopping the IV fluid/blood flow before removing the Disposable Cartridge. The Controller should only be plugged into a hospital grade outlet. Do not block the fan in the Controller as this may cause overheating. Although the Warmer has been tested to insure it will survive a drop of 1 m (3.28 ft.), care should be taken that the device is not dropped to reduce the potential of damage. Do not clean with: o ketones (MEK, acetone, etc.) or o abrasive cleaners. Do not sterilize the Warmer with: o steam sterilization (autoclave) or o dry heat. Do not disinfect or sterilize the Controller. Do not spray or pour cleaning solutions directly on the Controller. Do not allow cleaning solutions to accumulate on the Controller. When using the Controller mounted to an IV pole, it must be tightly secured on the pole no higher than 122 cm (48 in.) from the ground. The pole should have a base diameter of no less

To Begin Operation of the enFlow IV Fluid/Blood Warming System a) Place the Controller on a firm, level surface or on an IV pole with an outside dimension of no greater than 3.0 cm (1.25 in.) Two Controllers may also be mounted next to each other on an IV pole as shown below. The Controller’s display will have a “right-side-up” orientation regardless of its position.

b) Plug the Controller into a hospital grade outlet. c) Setting the clock to the local time is optional, but usually done on initial use. No changes in performance are affected by the clock’s setting. d) Connect the enFlow IV Fluid/Blood Warmer cable to the Controller. This action is accomplished in three steps: 1. Insert the male plug end of the Warmer into the female receptacle on the front face of the Controller. Push it in so that the plug cover is tight against the receptacle. 2. The plug and receptacle are “keyed” in both orientation and configuration. This feature ensures that the Warmer can only be plugged in properly. Additionally, it prevents other plug devices from fitting into this receptacle. 4400-0024 enFlow Operator’s Manual EN Rev. L 07/09

3. Turn right to lock. (See arrows on label.) e) The rear mounted I/0 (ON/OFF) switch on the Controller turns the power on and off. Switch the Controller to ON. Upon startup, the Controller conducts a self-test. The power indicator illuminates green, the Controller display flashes “enFlow”, a short audible “Beep” occurs, and the LED’s light up for about one (1) second. Note The Controller automatically switches for operation at either 115 VAC or 230 VAC f)

Open the covers on the Warmer by sliding them apart.

g) Connect the infusion set and or extension set to the Disposable Cartridge; then prime with fluid using standard medically approved protocols. Next, connect the infusion set to the patient and place the Disposable Cartridge into the Warmer. h) Completely close the covers on the Warmer by sliding them inward toward each other until the covers meet. Upon closing the covers, a short audible “Beep” occurs indicating that the Warmer self-test is being performed that confirms operation of temperature sensors and alarm indicators. After this process is complete, regulated power is delivered to the Warmer’s heating surface, which then begins heating the infusate through the Disposable Cartridge. Adjust the fluid flow to the desired rate. i)

Place the IV line in the IV Line clip in order to prevent it from kinking.
