AI Technical Summary

Technical Problem

Conventional fluid management and catheter exchange systems in medical procedures are prone to errors and risks, such as air bubbles and fluid selection mistakes, due to frequent detachment and reconnection of tubing, leading to inefficiencies and potential complications.

Method used

A suction system with an integrated fluid engineering control system featuring a valve manifold and hemostatic valves that allow selective connection of ports to lumens, electronically controlled to manage vacuum, saline, and contrast agent sources, with adjustable sealing forces to prevent backflow and control fluid delivery.

Benefits of technology

Enhances fluid management by reducing errors, preventing air bubbles, and ensuring precise fluid delivery, thereby improving the safety and efficiency of medical procedures involving multiple catheters.

Abstract

The fluid engineering system includes a cassette having a saline subsystem, a contrast agent subsystem, and a vacuum subsystem. The fluid engineering system further includes a splitter and a first tubing set coupled to the cassette and the splitter, the first tubing set having a single saline channel, a single contrast agent channel, and a single vacuum channel. The fluid engineering system further includes two or more hub assemblies, at least one of which has a third saline channel, a third contrast agent channel, and a third vacuum channel, and is configured to provide saline, contrast agent, and vacuum to the lumen of a catheter coupled to at least one of the two or more hub assemblies. The fluid engineering system further includes a second tubing set having a plurality of tube groups, each tube group coupled to the splitter and to one of the two or more hub assemblies.
