Intended Use

The enFlow IV Fluid Warmer is indicated for warming blood, blood products and intravenous solutions prior to administration. It is intended to be used by healthcare professionals in hospital, clinical and field environments to help prevent hypothermia.

Device Story

The enFlow IV Fluid Warmer is a system comprising a warmer unit, a power supply controller, and single-use sterile disposable cartridges. The cartridges feature a plastic housing and a biocompatible coated aluminum extrusion that creates an enclosed fluid path. The device operates by transferring heat generated via electrical resistance from the warmer to the infusate as it passes through the extrusion. It supports flow rates from KVO (Keep Vein Open) up to 200 ml/min, heating fluids to a maximum of 40°C. The system is used by healthcare professionals in hospital, clinical, and field settings. The current modification adds a strap accessory to secure the warmer to a patient's arm. The device helps prevent hypothermia by ensuring fluids are warmed prior to administration.

Clinical Evidence

No clinical data. The modifications did not require clinical testing to support substantial equivalence.

Technological Characteristics

System consists of a warmer unit, power supply controller, and sterile disposable cartridges. Cartridges utilize a plastic housing and biocompatible coated aluminum extrusion for heat transfer. Heating principle is electrical resistance. Standard Luer fittings are used for IV line connection. Accessory strap added for device securement. No changes to fundamental scientific technology.

Indications for Use

Indicated for warming blood, blood products, and IV solutions prior to administration in patients requiring fluid warming to prevent hypothermia. Intended for use by healthcare professionals in hospital, clinical, and field environments.

Regulatory Classification

Identification

An infusion pump is a device used in a health care facility to pump fluids into a patient in a controlled manner. The device may use a piston pump, a roller pump, or a peristaltic pump and may be powered electrically or mechanically. The device may also operate using a constant force to propel the fluid through a narrow tube which determines the flow rate. The device may include means to detect a fault condition, such as air in, or blockage of, the infusion line and to activate an alarm.

4. Legally Marketed Predicate Device:

> Substantial equivalence is claimed to: Vital Signs, Inc. enFlow Model IV Fluid Warmer (K112902) (a GE Healthcare Company)

5. Device and Change Description:

> The Vital Signs, Inc. enFlow IV Fluid Warmer consists of a Warmer, Controller (Power Supply) and single use sterile disposable cartridges, which are available with or without an IV tube extension set. The warmer will deliver infusate to a patient at a temperature of up to 40°C at flow rates of KVO (Keep vein open) to a maximum of 200ml/min.

The sterile disposable cartridges consist of a plastic housing and biocompatible coated aluminum extrusion which when combined form an enclosed fluid path. Heat, generated by electrical resistance, is transferred from the warmer to the fluid through the extrusion. Standard Luer fittings at the input and output allow the connection of standard hospital IV lines to the enclosed fluid path. The Controller serves as the power supply for the Warmer unit.

Description of Device Modification

The basis for this submission is to notify the FDA of the addition of a Warmer Strap to the enFlow IV Fluid Warmer. The Strap is an accessory whose function is to secure the enflow IV Fluid Warmer to the arm.

6. Indications for Use:

> The enFlow IV Fluid Warmer System is indicated for warming blood, blood products and intravenous solutions prior to administration. It is intended to be used by healthcare professionals in hospital, clinical and field environments to help prevent hypothermia.
