AI Technical Summary
Technical Problem
Existing fluid delivery systems face challenges in minimizing air introduction and effectively detecting flow rates, which can lead to inaccuracies in therapeutic delivery.
Method used
A rotatable flow indicator device is introduced, featuring a housing with a chamber, an inlet with a flow restrictor, and a compressible bulb made of hydrophobic material. This device is designed to minimize air introduction and allow for quick visualization of fluid flow by forming an air bubble that can be rotated to indicate flow rate.
Benefits of technology
The device effectively minimizes air generation and introduction into the fluid delivery system, allowing for accurate detection of flow rates and ensuring precise delivery of therapeutics.
