Home Infusion Pump Types: Which Infusion Pump Is Right for Your Therapy?

June 2, 2026

One of the first things patients notice when starting home infusion therapy is the pump, the device that controls how medication flows from the bag or cassette into your IV line. Not all infusion pumps are the same, and the type of pump you receive is matched to your specific medication, dose schedule, and lifestyle needs.


Pharmko uses multiple pump platforms depending on the therapy prescribed, and our nursing team trains every patient on their specific device before the first dose.


Why the Type of Pump Matters


The pump controls the rate, volume, and timing of your infusion. An incorrect rate can affect how your body tolerates the medication, too fast can cause reactions, too slow can reduce effectiveness or create scheduling problems. For therapies like Milrinone that run continuously, pump reliability is critical. For therapies like TPN that run overnight, battery life and alarm behavior matter.

The right pump for your therapy depends on:


  • The medication's required infusion rate and total volume per dose
  • Whether therapy is intermittent (a few hours, once or twice daily) or continuous (24 hours a day)
  • Your lifestyle — whether you need to be mobile during infusion
  • The access device you have (peripheral IV, PICC, port, or central line)
  • Whether multiple medications need to be programmed on the same device


Types of Infusion Pumps Used at Home


Electronic ambulatory pumps (CADD series)


CADD pumps (Continuous Ambulatory Drug Delivery) are small, programmable electronic pumps worn in a pouch or on a belt clip. They are commonly used for IV antibiotics, TPN, Milrinone, and other therapies requiring precise rate control over hours or days. CADD pumps use pre-filled medication cassettes or bags and have internal batteries that allow full mobility during infusion.

They are programmable by the pharmacist or nurse for your specific dose and rate, and include alarms for occlusion, air, low battery, and end-of-infusion. Pharmko primarily uses the CADD-Solis and similar platforms for multi-day and continuous infusion therapies.


Electronic stationary pumps


Stationary pumps are larger, more powerful devices used when the patient will be in one location during the infusion, typically for longer, higher-volume therapies administered while resting or sleeping. TPN is often delivered this way overnight. Stationary pumps offer high-precision programming and can manage larger bag volumes than ambulatory pumps.


Elastomeric (balloon) pumps


Elastomeric pumps are single-use, non-electronic devices that deliver medication through the pressure of an elastic balloon reservoir. As the balloon deflates, it pushes medication through a flow restrictor at a preset rate. They are commonly used for shorter-course IV antibiotic therapies and are lightweight, disposable, and require no programming or battery.

Elastomeric pumps are ideal for patients who need a simple, portable option for once-daily or twice-daily antibiotic infusions. Their fixed flow rate means they are not appropriate for therapies requiring adjustable rates.


Gravity infusion sets


For some therapies, particularly IVIG when delivered slowly over several hours, gravity infusion (without an electronic pump) is used. The rate is controlled by a manual roller clamp on the IV tubing and monitored by drip count. Gravity sets are simple and low-cost, but require more active monitoring and are only appropriate for specific therapies and patient situations.


Who Programs and Manages Your Pump


Pharmko's pharmacists program each pump before it is dispensed, setting the rate, volume, and any scheduled changes. Our nurses train patients and caregivers on how to load the cassette or bag, start and stop the pump, respond to common alarms, and care for the pump between infusions.

For a detailed overview of the supplies that come with your pump, see our guide on infusion pumps and supplies. For central line care guidance that applies to any pump type, that resource covers the daily habits that reduce infection risk.


What to Do If Your Pump Alarms


Every pump has a built-in alarm system. Common alarms, low battery, end of infusion, air detected in the line, are informational and do not typically mean something is wrong with your therapy. Your Pharmko nurse will walk you through each alarm and what to do.


If you see an alarm you do not recognize, or if you experience any new symptoms during an infusion, consult our guide on when to call your care team or reach our 24/7 after-hours support line directly.

Compounded medications are a routine part of modern care, but unlike mass-manufactured drugs, each one is prepared individually, which means the standards behind its preparation carry real weight. For providers who order or refer for compounded therapies, a working understanding of those standards is the clearest way to judge whether a pharmacy is safe to trust. This overview covers the standards that govern sterile compounding and what they mean for the medications your patients receive. Why Standards Matter More in Compounding A commercially manufactured drug is produced under FDA oversight in large, validated batches. A compounded medication is prepared for an individual patient, often in small quantities, sometimes because no commercial equivalent exists. That flexibility is exactly why it's clinically valuable — and why the standards around preparation exist. Without rigorous controls, the same customization that helps patients could introduce contamination or error. Our guide to our sterile compounding pharmacy describes how those controls come together in practice. The Regulatory Landscape Sterile compounding sits within a layered framework: The United States Pharmacopeia (USP) publishes the general chapters, most importantly <797> and <800>, that define how compounded preparations should be made and handled. State boards of pharmacy license and inspect pharmacies, including where they're permitted to ship. Multi-state operations must maintain licensure in each state they serve. Accreditation bodies (ACHC, NABP, PCAB) provide independent verification that a pharmacy meets recognized standards. Together, these create the accountability structure behind every compounded dose. USP <797>: Sterile Preparations USP <797> is the cornerstone standard for compounded sterile preparations. It governs the conditions and practices required to keep a preparation free of contamination, including personnel training and garbing, ISO-classified air quality and engineering controls, environmental monitoring, and beyond-use dating. For any medication infused directly into the body, <797> compliance is the baseline expectation, not a premium feature. USP <800>: Hazardous Drugs USP <800> adds a containment layer for hazardous drugs, protecting personnel, patients, and the environment from unintended exposure. It specifies containment engineering controls, PPE, and validated handling procedures for drugs identified as hazardous. When a preparation is both sterile and hazardous, it must satisfy <797> and <800> together. For the details, see our breakdown of USP <800> requirements . Accreditation: Independent Verification Standards are only meaningful if someone checks that they're being met. Accreditation from ACHC, NABP, and PCAB means a pharmacy has been inspected against national benchmarks by an outside authority. For a provider, accreditation is a shortcut to confidence: it signals that the pharmacy's claims about its processes have been independently validated. The Quality-Control Process Behind the standards is a repeatable process that governs each preparation: Pharmacist review of the prescription for appropriateness, compatibility, and dosing Preparation by trained technicians under aseptic conditions In-process and final verification by a licensed pharmacist Sterility testing or filtration validation where required This chain is what turns a standard on paper into a safe medication in a patient's hands. What This Means When You Order When you refer a patient for a compounded therapy, you're effectively extending your own standard of care into another facility. Knowing that a pharmacy is USP-compliant, accredited, and pharmacist-led lets you refer with confidence that the medication will meet the same expectations you'd hold for anything you administer yourself. If you're weighing options, our guide on how to choose a compounding partner walks through the criteria. The Pharmko Standard Pharmko compounds every TPN, IDPN, and IPN preparation in a USP <797>-compliant, ISO Class 5 cleanroom, under ACHC, NABP, and PCAB accreditation, with a licensed pharmacist reviewing and releasing each formula. For the patients who receive our preparations, many of them managing End Stage Renal Disease (ESRD), that standard is the point. Refer a Patient → · [1 (877) 540-2003]
