AI Technical Summary

Technical Problem

Existing fluid injector systems face challenges in effectively purging air from the syringe and fluid path set, leading to potential contamination, leakage, and uncertainty in complete priming, which can compromise patient safety during medical imaging procedures.

Method used

A priming tube configuration with a patient tube connector and a priming cap equipped with a sensing area and connection interface, along with a sensing device to detect the presence and characteristics of fluid, ensuring complete priming and air removal before the injection procedure.

Benefits of technology

The solution enables automated and reliable priming of fluid injector systems, reducing contamination risks and ensuring the fluid path is fully filled with fluid, enhancing safety and precision in medical imaging procedures.

Abstract

A prime tube for use with a fluid injector includes a patient tube connector and a connection interface for removably connecting the distal end of the patient tube connector to the proximal end of a prime cap. The connection interface includes a first connector at the proximal end of the prime cap and a second connector at the distal end of the patient tube connector. The prime cap is removably engageable with a prime tube housing having a sensing device for detecting whether the prime cap is filled with air or liquid in order to detect the presence of the prime cap and monitor the progress of the priming operation.
