• Autoinfu: Customers who have used the Autoinfu infusion pump describe it as an “affordable pump with better performance than more expensive models and without a long learning curve.” The portable peristaltic infusion pump safely and reliably delivers infusion therapy thanks to the programmable settings and customizable treatment details, among other state-of-the-art features.
• Baxter: Baxter creates its pumps with a patient safety priority through accurate and error-free fluid and drug infusion. Its Sigma Spectrum IV pump ensures a smooth workflow using the Smart pump technology that allows automatic wireless connectivity to the drug library on startup and seamless integration with the EMR system.
• Fresenius: The Fresenius Ivenix Infusion System is a winner of the MedTech Breakthrough Award for its innovative technology solution in drug infusion. It is designed to pump differently, and the manufacturer claims it is the only infusion pump in the market that uses a pneumatic pumping mechanism.

So, in this article, we compare the Autoinfu infusion pump, Baxter’s Sigma Spectrum IV pump, and Fresenius’ Ivenix Infusion System on the following features:

• Boosted Portability and Durability.
• Enhanced Infusion Assessment on a User-Friendly Interface.
• Advanced Patient Safety with Dose Error Prevention Pump Designs.
• Affordable Pricing.

The Autoinfu infusion pump is built to provide easy and safe portability and advanced durability thanks to the following features:

• A lightweight pump weighing only 1.7kg (3.75lb).
• An ergonomic handle that makes handling and moving the pump easy and secure.
• A long-lasting battery that runs for 10 hours when fully charged, making the Autoinfu reliable during power emergencies and an excellent choice for home and mobile care.
• An IPX3 waterproof rating. It means the pump can withstand sprayed water and vertical water drops.
• A custom pole and stand to boost portability and pump support. The stand has lockable wheels for enhanced security and adjustable height from 57-73 inches. Even then, the Autoinfu pump design allows it to be placed safely on any secure stand.

The Fresenius infusion pump is made with easy portability and durability in mind. Here’s why:

• A lightweight pump of 2.2kg (4.8lb).
• A roll-cage secure-grip handle for safe pump handling and portability.
• 8-hour battery run time, good enough for power emergencies and home and mobile care.
• A strong, impact-resistant casing with an IPX3 waterproof rating, allowing spray cleaning and withstanding most disinfectants.
• The easy and quick IV pole mounting and release enhance portability.

Although the Baxter Sigma Spectrum IV pump is lightweight, it lacks the ergonomic features of Autoinfu and Fresenius. You need the designated tandem carrier to support it on an IV pole. However, its 8-hour battery performance supports portability for home and mobile care.

The Autoinfu infusion pump has the following advanced features that ensure enhanced patient safety during infusion.

• Audiovisual alarm notifications in case of air bubbles, up or downstream occlusion, open door, end of infusion, expiry of standby time, low or discharged battery, drip sensor error, and several other errors. The visual alarm feature is strategically placed to ensure easy identification. 

• A cutting-edge drip sensorthat ensures consistent infusion delivery at the right infusion rate, volume, and interval.
• A built-in titration error prevention featurethat stops programmed infusion dosage if it is beyond the allowed limits for titration infusions. This is a great patient safety feature, considering that 90% of infusion programming errors occurring with high-risk drugs are titrations.

• A built-in, one-step titration error prevention feature that blocks inaccurate entries of drug dosage, especially in high-risk titration infusions.
• A cue to confirm that the flow of critical medication is initiated when it should.
• The prompt to confirm that the primary and secondary infusion lines flow rates are as prescribed in order to avoid unintended drug interactions.

• Accurate drug dosage, thanks to the pneumatic infusion mechanism that measures and regulates infusion flow, independent of fluid density, bag placement, and patient position or movement.
• Automatic adjustment when occlusion or pressure error is detected.
• Alarm to warn the user of duplicate or incompatible drugs.
• Built-in anti-free-flow features, regardless of the operating conditions.
