On this page
IV equipment is the set of devices that gets fluid from a container into a vein: a catheter for access, an administration set between container and patient, flow control (regulators, clamps, pumps) and a stand to hold it all. This page maps each class of equipment to the FDA regulation that defines it, then to the CASRAI guide that covers it in depth. Who uses it: nurses and other clinic staff, central supply and purchasing teams, and students learning the vocabulary.
What IV equipment includes
Under 21 CFR 880.5440, an intravascular administration set is “a device used to administer fluids from a container to a patient’s vascular system through a needle or catheter inserted into a vein.” Everything else on the list below either gets the fluid into the set, controls its flow, or holds it up. Supplies that wrap around this core (dressings, antiseptics, replacement intervals) are covered in IV supplies: components and CDC replacement intervals.
How an administration set is built
The regulation says the set “may include” a needle or catheter, tubing, a flow regulator, a drip chamber, an infusion line filter, an I.V. set stopcock, fluid delivery tubing, connectors between parts of the set, a side tube with a cap to serve as an injection site, and a hollow spike that penetrates and connects the tubing to an I.V. bag or other infusion fluid container. Those parts have their own CASRAI guides:
- IV drip chamber: the chamber in the line, where drop factor and venting are labeled.
- IV roller clamp: a manual flow regulator on the tubing.
- IV extension tubing: added tubing, compared by length and priming volume.
- T-connector IV extension set: a branched connector set.
Pumps and how FDA defines them
21 CFR 880.5725 defines an infusion pump as “a device used in a health care facility to pump fluids into a patient in a controlled manner.” It may use a piston, roller or peristaltic pump, may be electrically or mechanically powered, and may detect a fault such as air in the line or a blockage and sound an alarm. For the types compared by setting, see types of IV pumps. A pressure-based alternative to a pump is described in pressure infusor bags.
IV equipment by role
| Role | Equipment | FDA definition and class (21 CFR) | CASRAI guide |
|---|---|---|---|
| Access | Intravascular catheter | 880.5200: a slender tube inserted into the vascular system for short-term use (under 30 days) to sample blood, monitor blood pressure or administer fluids. Class II (performance standards). | What is an IV catheter |
| Container to patient | Administration set | 880.5440: carries fluid from a container to the vascular system. Class II (special controls). | IV supplies |
| Flow control | Infusion pump | 880.5725: pumps fluids in a controlled manner in a health care facility. Class II (performance standards). | Types of IV pumps |
| Flow control | Flow regulator, drip chamber (parts of the set) | Listed as possible parts of the administration set in 880.5440, so they sit under that classification when part of a set. | Roller clamp, drip chamber |
| Support | Infusion stand (IV pole) | 880.6990: a stationary or movable stand that holds infusion liquids, accessories and other devices. Class I (general controls), exempt from premarket notification. | IV pole clamp |
The class matters because it sets the level of FDA control: Class I is general controls only, Class II adds special controls or performance standards.
Brands and units: how to read a listing
The regulations above describe a device by what it does, not by who makes it. A catalog line labeled with a brand or a unit of sale (a single set, a pack) should therefore be matched to the function in the table: which role does it fill, and which regulation describes that device? This page does not rank brands or units. The administration set, pump and stand named on a listing are what carry the classification.
Common mistakes
- Treating “IV set” and “IV pump” as one product. The set is Class II under 880.5440; the pump is a separate Class II device under 880.5725.
- Assuming every part is sold separately. 880.5440 lists the catheter, drip chamber, regulator and spike among the parts a set “may include”, so a listing may bundle them.
- Assuming a stand carries the same class as the set. Under 880.6990 the infusion stand is Class I.
- Confusing the bag with the equipment around it. The container is what the set connects to; how long an IV bag takes explains the container side.
For what can go wrong at the access site, see intravenous infiltration. The CDC publishes recommendations for preventing intravascular catheter-related infections; the replacement intervals are summarized in the IV supplies guide above.
FAQ
What counts as IV equipment?
A catheter for access, an administration set, flow control such as clamps or an infusion pump, and a stand. The table above gives the FDA regulation for each.
What is in an IV administration set?
Per 21 CFR 880.5440 it may include tubing, a flow regulator, a drip chamber, a filter, a stopcock, connectors, an injection-site side tube and a spike for the fluid container, and in some sets the needle or catheter.
Are IV pumps regulated by the FDA?
Yes. 21 CFR 880.5725 classifies the infusion pump as Class II (performance standards).
Does the brand change the FDA class?
The classification in 21 CFR is written for the device type, such as administration set or infusion pump, not for a brand.
Are IV poles regulated?
The infusion stand is Class I (general controls) under 21 CFR 880.6990.
