IV Administration Set (Gravity, 1 Port, 20 Drops/mL, 103″ Tubing)

An IV administration set is the sterile tubing assembly used to deliver IV fluids by gravity (no pump). The described set is a primary gravity IV set with ~103 inches (≈262 cm) of PVC tubing, calibrated for 20 drops = 1 mL (“20 gtt/mL”). It has one needleless injection port (Y-site) near the patient end for drug/infusion access, and a built-in roller (pinch) clamp for flow shut-off. Notably, it is specified “without filter” and “without flow regulator,” meaning it has no inline filter (e.g. 0.2 μm) and no special dial-regulator – flow is controlled only by the clamp and bag height. Key features include:

• Drip Factor: 20 drops/mL (macrodrip). In a macrodrip set, 20 drops of fluid equal 1 mL. (By contrast, pediatric “microdrip” sets use 60 gtt/mL for finer control.) At 20 gtt/mL, one can calculate flow by drops/min = (mL/hr × 20) ÷ 60.
• Tubing & Priming Volume: Total length ≈103″ (about 262 cm). The long tubing gives a large dead volume: priming (the fluid needed to fill the line and purge air) is roughly 30 mL. (Priming volume is defined as the fluid required to fill the entire IV tubing and remove air.) A priming volume of ~30 mL means you must flush ~30 mL through before the line is fully primed.
• Injection Port: 1 port (needle-free Y-site) on the tubing, typically placed several inches from the patient end. This single Y-type port allows IV medication or fluids to be added via a syringe or secondary line.
• Spike/Connector: Standard non-vented spike to puncture an IV bag (used with collapsible bags). The distal end has a Luer-lock connector (usually female) to attach to the patient’s IV catheter or extension. (The listing notes a “male Luer Lock connector[hip]” on one end, which refers to the type of adapter in the set.)
• Flow Control: A manual roller (pinch) clamp on the tubing provides on/off control. There is no additional flow regulator (the product spec explicitly says “without flow regulator”). Thus, flows are adjusted by bag height and clamp adjustments, not by a calibrated dial.
• Filter: None. The set is specified “without filter”, so it contains no inline microfilter. (Some special sets include 0.2 μm or 15 μm filters for blood/TPN; not in this case.)
• Material & Safety: Medical-grade PVC tubing (explicitly DEHP-free, latex-free). Many IV sets are now made without phthalates (DEHP) or natural rubber latex for safety. The Henry Schein description of a similar set reads: “PVC tubing… DEHP Free… Sterile… Not Made With Natural Rubber Latex”. This set is provided sterile in individual packaging and is disposable (single-use).
• Priming & Use: Before connection to the patient, the line must be primed to eliminate air. The priming volume (~30 mL) is printed on the label. In practice, you spike the IV bag, fill the drip chamber ~1/3 full, clamp the tubing, and flush fluid through until all air is out. Then attach the patient-end connector. To begin infusion, open the roller clamp. Flow is monitored by counting drops (20 drops = 1 mL) and adjusting as needed.

Usage and Operation

This set is intended for gravity IV infusion of fluids/medications in adults or larger children. Hang the IV bag above patient level, spike the bag with the set’s non-vented spike, then prime the tubing as above (keep clamp closed until primed to avoid air embolus). After connecting to the patient’s catheter, open the clamp to start flow. Since there’s no regulator, adjust infusion by changing the clamp position and bag height. For example, to deliver 60 mL/hr with a 20 gtt/mL set, aim for 20 drops per minute (60 mL/hr × 20 gtt/mL ÷ 60). The single Y-injection port allows IV piggyback or syringe injections at the patient end. (Because the tubing is relatively large and has a long dead space, any drug pushed into the line must traverse or fill about 30 mL of tubing before reaching the patient.) Always verify the drop rate and clamp function regularly.

Safety and Related Information

Like all primary IV sets, this product is supplied sterile and for single use only. Do not use if the package is opened or damaged. Being DEHP- and latex-free, it reduces the risk of plasticizer exposure and latex allergy issues. Confirm that the clamp is fully closed when not infusing to prevent leaks or air entry. Ensure all connections (spike, Luer locks) are secure. Because it has no inline filter, use this set only when filtering is not required (e.g. routine IV fluids). Finally, after use the set should be discarded per biohazard protocols.

Summary: A “Gravity, 1 Port, 20 gtt/mL, 103″ tubing, without filter, without regulator” IV set is a short primary infusion line with one needle-free Y-port, macrodrip calibration, and a simple roller clamp. It holds about 30 mL when primed, contains DEHP-free PVC tubing, and is used to infuse IV fluids safely by gravity (with flows set by drop count and clamp position).
