Accuracy of Gravity-Based Automatic Infusion System for Chemoport Intravenous Infusion

Area of Science:

• Oncology
• Medical Devices
• Pharmacology

Background:

• Traditional infusion pumps may fail to detect extravasation, risking tissue damage from vesicant drugs like chemotherapy.
• Gravity infusion, while safer for vesicants, faces accuracy issues due to variable factors like fluid height and venous pressure.
• Existing intravenous flow regulators for gravity infusion are limited by environmental and physiological influences on infusion rates.

Purpose of the Study:

• To evaluate the accuracy of Accudrip, a novel gravity-based automatic infusion control device.
• To determine if Accudrip can reliably deliver fluids at predetermined rates, correcting for fluctuations.
• To assess the clinical applicability of Accudrip in cancer patient chemotherapy administration.

Main Methods:

• The study involved 59 cancer patients receiving anticancer drugs.
• Accudrip's actual administration rates were measured and compared against theoretical rates under diverse conditions.
• Data were collected and analyzed over 100 measurement instances.

Main Results:

• Accudrip demonstrated an average error rate of 4.75% when comparing theoretical and actual administration rates.
• This level of accuracy was deemed clinically sufficient for fluid and medication delivery.
• The device maintained consistent accuracy across various infusion scenarios.

Conclusions:

• Accudrip, a gravity-based automatic infusion system, exhibits high accuracy comparable to theoretical rates.
• The device performs reliably even with multiple infusion conditions in cancer patients with chemoports.
• Accudrip is poised to significantly enhance drug administration accuracy and reduce adverse events in clinical practice.
