HIgH-Flo needles are made with safety and comfort in mind. Every feature of HIgH-Flo is optimized for sub-q. These needles were designed specifically to work with RMS Precision Flow Rate Tubing™ and a Freedom Pump as a total infusion system, with options for every patient.

HIgH-Flo Subcutaneous Safety Needle Sets™ Key Features:

Backcut needle tip

Minimizes damage, scarring & local site reactions. Promotes faster healing.

Flexible flying hinge

Wings have great flexibility & allow each needle to stay in place without any tenting.

Safety closure

Protects against accidental needle sticks.

Custom luer

Designed to provide even flow to every site.

Set options

Sets are available in single, double, triple, quad, penta and hexa configurations.

Needle lengths

Needles are available in 4mm, 6mm, 9mm, 12mm, & 14mm lengths.

Needle gauges

26g designed for sub-q rates up to 30ml/hr/site & 24g for up to 300ml/hr/site.

Tubing length

Efficient and practical 20” length (in 26g sets) for less tangles & faster flow rates.

Extension set

Available for those who prefer a longer length.


Combines sets for more than 6 sites (up to 8), or to infuse with different length needles.

3M Tegaderm™

Transparent dressing that is preferred by most patients is included with all sets.

Secrets of Infusion

The biggest “dirty little secret” out there is that infusion adverse effects are NOT normal.

  • FAQ
Why do you call them HIgH-Flo?

Made for sub-q, 26 gauge HIgH-Flo (high performance flow) sets offer faster infusion rates than typical 27 gauge needle sets. Note: If you are transitioning from 27 gauge, your provider might give you a different F-numbered Precision tubing set to keep your infusion time about the same.

How can the smaller 26 gauge HIgH-Flo sets flow at the same rate as other brand sets using larger 24 gauge needles?

HIgH-Flo needle sets are carefully designed to optimize fluid flow for the most efficient handling of drugs. This efficiency translates into higher flow rates from smaller diameter needles.

What is the least painful way to insert a HIgH-Flo needle?

Many patients tell us that they grab the wings above the needle, tightly pinch the skin at the site close together between their fingers, and insert the needle straight into the pinched area with a dart-like motion. You may notice that the HIgH-Flo butterfly wings are very flexible, making this procedure easy. It is recommended that each site should be about 2” apart and needles should be inserted at a 90° angle. Make sure any alcohol has evaporated off your sites, and insert all needles dry. You can also talk to your provider about premedication.

Why is a 3M Tegaderm™ dressing supplied with each needle?

Consensus from several medical centers and many patients was that genuine 3M Tegaderm™ is preferred by most patients, so we include it with your needles. We were told it had the least irritation and best adhesion to the skin. If you are a patient with dry or sensitive skin and find that the 3M Tegaderm™ is irritating, you may need to try different dressings, paper tape, or a cloth wrap. Ask your healthcare provider for suggestions.

How many configurations are available for HIgH-Flo needles?

We have needle lengths in 4mm, 6mm, 9mm, 12mm, and 14mm. We offer single, double, triple, quad, penta and hexa leg set configurations. If there is a need for a special needle length or configuration, give us a call.

What is the maximum number of needles possible at one time?

We have tested up to eight needles at one time using our Low Residual Y-Connector to join two quadfurcated sets. The Y-Connector can also be used to make up a multiple set from a limited inventory, for example, creating a four site system using two of the bifurcated sets. A six site administration could be assembled by using two trifurcated sets and the Y-Connector.

Can HIgH-Flo needles be used with other pumps besides the FREEDOM60®?

Yes. Our needles are compatible with other pumps. However, only our pumps offer Dynamic Equilibrium, which automatically adjusts the flow rate downward if the tissues at the infusion site become saturated. While the answer is “Yes,” the FREEDOM60® and FreedomEdge™ are recommended for administration of subcutaneous immune globulin because they will adjust to the patient’s needs and reduce discomfort.

Why are HIgH-Flo needles considered "safety" sets?

The butterfly wings ‘snap shut’, at the ends, to cover the needle after use. This feature of RMS HIgH-Flo needles is designed to help prevent needle stick injuries.

Do HIgH-Flo sets eliminate concerns about different amounts of medication going to each infusion site when a multi-leg needle set is used?

Achieving even flow prevents some sites from getting more drug than others and over-filling, thus reducing pain, swelling and oozing when performing multi-site infusions. HIgH-Flo Subcutaneous Safety Needle Sets™ are carefully designed and tested for equal flow to every needle. The design and quality control during manufacture minimize factors which can interfere with fluid flow and cause uneven distribution. However, varying flow rate also might be due to factors which are unrelated to the needle sets, such as incorrect needle length, or something about the site at which a needle was placed, such as scar tissue or over a muscle.
