North Carolina State University is seeking a partner in industry to develop an ultrasonic flow meter for intravenous flow rate measurements.
In order to prevent serious adverse effects on the patient, intravenous (IV) delivery of drugs requires accurate monitoring and precise control of medication injection flow rate. Errors can lead to death or serious harm. IV medication has a significantly higher rate of associated deaths than other routes of medication administration. The two methods of IV administration gravity infusion and syringe pump measure the fluid rate at the source however this may not be the same rate at the injection port.
Researchers at North Carolina State University have developed a transit-time difference flow meter for IV applications. It is non-invasive and can be attached at any position on the outside of the injection tube, due to its strap bandage system. This would allow the fluid flow rate close to the injection port to be monitored, ensuring that patients are receiving the correct dose. A composite transducer has been engineered for clinical dosage rates in the medical field and small diameter tubing. This system could be used with both the gravity infusion method and the syringe pump method.
This new invention would enable the accurate monitoring of extremely low flow rates to ensure the correct dosage of administered medications.
- Capable of detecting a low flow rate ( < 0.005 m/s)
- Optimized for small diameter tube
- Engineered for clinically relevant dosage rates in the medical field
- System can be attached at any point along the intravenous tube
