No
The description focuses on basic fluid warming technology with user-selectable temperature settings and does not mention any AI/ML terms or capabilities.
No
The device warms fluids for administration but does not directly treat or diagnose a disease or condition. Its purpose is to prepare fluids rather than provide a therapeutic effect itself.
No
The device is described as a "Fluid Warming System" intended "for the warming of fluids prior to administration." It does not mention analyzing or interpreting any physiological data or medical conditions to diagnose.
No
The device description explicitly states that the ComfortMate™ Fluid Warming System consists of a reusable fluid warming unit and a single-use warmer disposable, which are hardware components.
Based on the provided information, the ComfortMate™ Fluid Warming System is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use is "for the warming of fluids prior to administration." This describes a physical process applied to a substance that will be introduced into the body, not a test performed on a sample taken from the body to diagnose a condition.
- Device Description: The description details a system for heating fluids as they flow through a disposable component. This is a therapeutic or supportive function, not a diagnostic one.
- Lack of IVD Characteristics: The document does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Detecting or measuring substances in samples
- Providing information for diagnosis, monitoring, or screening
The ComfortMate™ is a medical device used to prepare fluids for patient administration, falling under a different regulatory category than IVDs.

Device Description
The ComfortMate™ Fluid Warming System is designed to warm fluids to 30℃ to 37℃ prior to patient administration, at flow rates of up to 200 ml/min. The ComfortMate™ consists of a reusable fluid warming unit and a single-use warmer disposable. To use the ComfortMate™, the warmer disposable is inserted into the warming unit. Once the warming unit's door is closed, the warmer disposable comes into contact with the warming unit heater plates. Fluids are warmed as they flow through the disposable. The knob on the front panel allows the user to choose from 9 temperature comfort settings. The ComfortMate™ has not been validated for the warming of blood or blood products.

§ 880.5725 Infusion pump.
(a)
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.(b)

Dear Ms. St. Onge:
This letter corrects our substantially equivalent letter of October 24, 2001.
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809 ); medical device reporting (reporting of
