Bench testing only. Performance testing validated heating accuracy across various inlet temperatures and flow rates, and system response to flow irregularities. Environmental and electrical safety testing conducted per IEC 60601-1, IEC 60601-1-2, and IEC 60601-1-6. Risk management performed per ISO 14971:2012.
Technological Characteristics
Inline resistive heating system. Fluid path: stainless steel heat exchanger, PVC tubing, luer connections. Base Unit: firmware-controlled electronics. Power: rechargeable battery or AC power supply module. EPP housing for thermal/electrical insulation. Dimensions: BU with AC module ~300x190x180 mm. Standards: IEC 60601-1, IEC 60601-1-2, IEC 60601-1-6, ISO 14971.
Indications for Use
Indicated for medical emergencies or surgeries requiring warm fluid administration to treat patients, or whenever parenteral introduction of normothermic fluid is desired.
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.

### Purpose of 510(k)
The purpose of this 510(k) is to add the AC power supply module as an additional power source to the rechargeable detachable battery of the QiF blood and fluid warmer.
#### Indications for Use
The QiF Blood and Fluid Warmer device is intended for warming blood, blood products, and intravenous fluids prior to administration. It is intended to be used by healthcare professionals in hospital, clinics, and field environments, to help prevent hypothermia.
#### Device Description
The Quality in Flow QiF Blood and Fluid Warmer is a portable sterile Fluid Path, in-line Blood and Fluid Warmer.
The QiF device is composed of the following main components:
{4}------------------------------------------------
- 1. Disposable Unit (DU) - The disposable cartridge is made of a plastic oval box encasing a spiral Stainless Steel (SS) heat exchanger tube. The DU is located between the fluid container (intravenous solution or blood product) and the treated patient, outside of the patient body. The DU has a standard intravenous tube extension. The DU comprises the temperature sensors.
- 2. Base Unit (BU) – The BU controls the performance of the system and the outflow fluid temperature. The power source is a rechargeable detachable battery located within the BU or an AC power supply module; the BU contains firmware (SW) and electronics (HW).
- 3. Connecting Cable (CC) - a cable that connect between the BU and the DU to facilitate the transfer of data and electrical current.
# Substantial Equivalence Discussion
Both the cleared device and the modified QiF Blood and Fluid Warmer are a portable, inline Blood and Fluid Warmer located between the fluid container (intravenous solution or blood product) and the treated patient, outside of the patient body. The device is comprised of a Base Unit (BU) and a sterile disposable cartridge (Disposable Unit). The Disposable Unit (DU) is composed of a plastic oval box encasing a spiral stainless steel heat exchanger tube. The Base Unit contains Firmware (software) and electronics (HW). The Base Unit controls the performance of the system and the fluid outflow temperature. The power source is either a rechargeable detachable battery located within the Base Unit or an AC power supply module (also referred as "AC unit"). The DU has a standard intravenous tube extension.
The QiF modified device has the same indications for use as its predicate device. A Substantial Equivalence Comparison table between the subject device and the predicate device is presented below:

The differences between the subject device and the predicate device are the addition of the AC power supply, AC power supply casing, narrowing of the storage, operating, and altitude conditions of use.
The operating and storage conditions and the altitude of use of the AC power supply module are within the ranges of the QiF cleared predicate device; The labeling of the QiF device operated with the AC power supply module specifically indicates the storage and operating conditions and this difference does not raise different questions of safety and effectiveness.
Based on the aforementioned modifications to the subject device, the subject device does not raise different types of safety and effectiveness questions when compared to the predicate device.
## Performance Testing Summary
Based on a risk analysis of the changes, the following testing was conducted to demonstrate substantial equivalence to the predicate device:
- . Performance testing, including heating fluid to set-point temperature from various inlet temperatures in various flow rates and system performance through flow rate irregularities, demonstrated that the subject device has equivalent performance to the predicate device.
- Validation of the subject device included performance testing, environmental testing ● and electrical safety testing per:
- O IEC-60601-1:2005: General Requirements For Basic Safety And Essential Performance
- IEC 60601-1-2:2010 Medical Electrical Equipment. General Requirements o For Basic Safety And Essential Performance - Collateral Standard: Electromagnetic compatibility
- IEC 60601-1-6:2013 Medical Electrical Equipment Part 1-6: General o Requirements For Basic Safety And Essential Performance - Collateral Standard: Usability
{9}------------------------------------------------
- . A risk analysis was completed in accordance with ISO 14971:2012, Medical Devices - Applications of Risk Management to Medical Devices
In all instances, the subject device functioned as intended and demonstrated equivalent performance to the predicate device.
## Conclusions
The modifications to the device do not raise different questions of safety and effectiveness and are supported by risk management activities. The QiF Blood and Fluid Warmer is substantially equivalent to the QiF Blood and Fluid Warmer, cleared under K171215.
