Sensorized IV infusion therapy for safer drug administration
Eliminating IV flow-related medication errors in neonatal and paediatric intensive care
The Problem
Safeguarding critically ill infants
Every year, 1 in 10 newborns is born prematurely, requiring admission to Neonatal Intensive Care Units (NICUs). NICU patients are vulnerable and have very low tolerance for medication errors, as evidenced by a high mortality rate of 7%1. However, intravenous (IV) infusion therapy, which is the primary mode of drug delivery in intensive care, suffers from flow rate errors in over 60% of cases2, due to a variety of reasons such as occlusions, pump displacement, multi-infusion dynamics, and so on3.
Within NICUs, where an estimated 100 million IV infusions are administered annually worldwide, precision is paramount, particularly considering the prevalence of 'high-alert' drugs that carry significant risks of adverse events. The existing shortcomings in IV infusion procedures contribute to the likelihood of over or under dosage, consequently elevating the risks of serious clinical consequences such as neurodevelopmental impairment4 and mortality5. These problems have been recognized by regulatory bodies6,7 and major MedTech companies7.
Improving alarm responsiveness in low flow rates
It's essential to maintain low infusion rates (< 2 mL/hr) to prevent fluid overload in infants. However, at such low infusion rates, current systems can take up to an hour to detect blockages9, which is longer than the half-life of critical drugs. This delay significantly increases the likelihood of adverse drug events in the NICU, where each IV-related adverse event can add up to €10k in additional healthcare costs.
The FDA has highlighted this concern, issuing safety alerts about the severe clinical consequences of IV flow instability at low rates in neonatal patients7,8. Similarly, major MedTech companies have also acknowledged the risks of infusion interruption while administering high-risk IV infusions8. Urgent action is thus necessary to enhance the safety of these vulnerable patients.

Frequently Asked Questions
Where is the technology applicable?
Rely-V is designed for NICUs and PICUs but the principle can be applied wherever IV infusions need monitoring, including adult ICUs, general care, and home care.
Can the sensor technology be applied outside the IV infusion monitoring use case?
Absolutely! Our sensors are also undergoing testing for various biomedical applications requiring flow sensing. Contact us for more details.
What stage is the technology at?
Currently in the design/development stage with a Technology Readiness Level (TRL) of 4. We're conducting preclinical tests (ex vivo and in vitro) to create a fully functional prototype.
Can I get Rely-V in my hospital?
Rely-V will be available as a research-use device in 2026. However, we are already partnering with NICUs for product development and pilot studies. Contact us to explore our prototypes!
