Background: Tube patency is essential for patients who receive enteral nutrition via a small bore naso-enteral feeding tube. Formation of a clog within these tubes interrupts and delays delivery of nutrition. Unfortunately, current tubes are prone to clogging. A small-bore naso-enteral feeding tube that gradually increases in diameter over its length could mitigate the risk of clog formation.
Methods: Small-bore feeding tubes that increase in diameter over their length, were evaluated relative to current (constant diameter) tubes to determine if a tapered tube design could reduce the pressure required to clear an established clog in benchtop testing at pressures representative of those achieved safely in the clinical environment.
Results: Incorporating a tapered design into an 8F nasal feeding tube significantly reduced the pressure to expel an established clog by 62% (p < 0.05; 258.6 kPa vs. 710.8 kPa, respectively).
Conclusion: When compared to constant diameter tubes with the same proximal outside diameter, a tapered tube design permits clearance of an established clog at lower pressure.
期刊介绍：
The Journal of Medical Devices presents papers on medical devices that improve diagnostic, interventional and therapeutic treatments focusing on applied research and the development of new medical devices or instrumentation. It provides special coverage of novel devices that allow new surgical strategies, new methods of drug delivery, or possible reductions in the complexity, cost, or adverse results of health care. The Design Innovation category features papers focusing on novel devices, including papers with limited clinical or engineering results. The Medical Device News section provides coverage of advances, trends, and events.
