AI Technical Summary

Technical Problem

Intravenous catheter devices are prone to occlusion, leading to inefficiencies and increased costs due to the need for replacement, and existing solutions like rigid tubes can also become occluded, complicating fluid administration and blood sampling.

Method used

A probe with a selectively permeable distal end is integrated into the catheter, allowing controlled fluid flow and occlusion management through a probe assembly with a core segment, coil segment, and displacement segment, enabling the distal end to be selectively opened or closed to bypass or remove occlusions.

Benefits of technology

The probe minimizes occlusion risk and allows controlled fluid inflow/outflow, maintaining catheter functionality and reducing the need for replacement, thus enhancing the catheter's effectiveness and reducing patient burden and costs.

Abstract

The intravenous catheter device can have a probe with a selectively permeable distal end that can be inserted through the catheter while the catheter is in place in a vein to facilitate fluid flow into or out of the catheter, such as to clear an obstruction or reposition the catheter. Because of its selective permeability, the distal end of the probe can minimize the chance of obstruction while the probe is inserted into a vein and can control the rate at which fluid flows into or out of the catheter.
