Intended 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 hospitals, clinics and field environments, to help prevent hypothermia.

Device Story

Portable, inline blood and fluid warmer; used in hospitals, clinics, and field environments by healthcare professionals. System consists of a Base Unit (BU) with rechargeable battery, firmware, and electronics; a sterile, single-use Disposable Unit (DU) containing a spiral stainless steel heat exchanger; and a connecting cable. Device placed between fluid container and patient. BU controls heating process and outflow temperature (set point 38 ± 2 °C) via resistive heating. Provides visual/audio notifications for overheat, under-heat, low battery, and flow irregularities. Safety features include system self-test, overheat cut-off, and battery under-voltage protection. Prevents hypothermia by delivering normothermic fluids; helps maintain patient temperature during surgery or emergency care.

Clinical Evidence

Bench testing only. No clinical data provided. Performance testing verified the device warms plasma to the set point of 38 ± 2 °C. No studies were performed to evaluate the effects on clotting factors in plasma products.

Technological Characteristics

Portable inline warmer; resistive heating. Components: Base Unit (electronics, firmware, rechargeable battery) and sterile Disposable Unit (plastic oval box, spiral stainless steel heat exchanger, PVC tubing). Heat insulation via expanded polypropylene (EPP) box. Flow rate up to 160–180 ml/min. Dimensions: BU 235x160x75 mm; DU 210x160x45 mm. Operating conditions: 41°F–104°F, 15%–93% RH. Altitude: -1312 to 15,000 ft.

Indications for Use

Indicated for warming blood, blood products, and intravenous fluids prior to administration in patients requiring normothermic fluid introduction during medical emergencies or surgeries. Intended for use by healthcare professionals in hospitals, clinics, 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.

It is intended to be used by healthcare professionals in hospitals, clinics and field environments, to help prevent hypothermia. #### 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: - 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 {1}------------------------------------------------ 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: the BU contains firmware (SW) and electronics (HW). - 3. Connecting Cable (CC) a cable consisting of data and power wires connects between the BU and the DU to facilitate the transfer of data and electrical current. ## Purpose of 510(k) The purpose of this 510(k) is to replace the contraindication against plasma warming with the QiF device with a precaution statement. #### Performance Data Performance tests were performed in order to demonstrate that the device has equivalent performance to its predicate. Specifically, testing was conducted to verify that the QiF device will warm plasma to the device set point temperature (38 ± 2 °C; 98.6±3.6°F). In all instances, the device functioned as intended and demonstrated equivalent performance. Studies have not been performed to evaluate the effects on clotting factors in plasma products following warming with the QiF Blood and Fluid Warmer. #### Technological Characteristics The QiF Blood and Fluid is not changed, thus it has identical technological characteristics as the predicate QiF Blood and Fluid Warmer. The QiF Blood and Fluid Warmer is 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 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 a rechargeable detachable battery located within the Base Unit. The DU has a standard intravenous tube extension. #### Substantial Equivalence An SE Table is presented below: {2}------------------------------------------------ | | Quality in Flow – QiF Blood and Fluid Warmer model 01 [Subject] | Quality in Flow – QiF Blood and Fluid Warmer model 01 [K163708] | SE Justification | |----------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------| | Indications for Use | Intended for warming blood, blood products, and intravenous fluids prior to administration.
