A new remote-controlled cholangiography injection device significantly reduces adverse reactions and eliminates radiation exposure for clinicians during X-ray cholangiography procedures. This innovation enhances patient safety and operator protection.

Area of Science:

Medical Imaging
Medical Devices
Interventional Radiology

Background:

X-ray cholangiography is crucial for diagnosing biliary tract diseases.
Manual contrast dye injection poses risks of adverse reactions and occupational radiation exposure.
A need exists for a safer, remote-controlled injection system.

Purpose of the Study:

To develop and evaluate a novel remote-controlled cholangiography injection device.
To assess the device's impact on adverse reaction rates, image quality, and radiation dose.
To compare the device's performance against manual injection methods.

Main Methods:

A remote-controlled injection device was designed, incorporating an injection pump, pressure sensor, and wireless remote panel.
The device was used for X-ray cholangiography in patients with external biliary drainage.

Keywords:

Cholangiography Equipment design Injection device Occupational exposure Remote control technology

Image quality, adverse reactions, and radiation exposure were systematically evaluated.

Main Results:

Successful and smooth cholangiography was achieved in all patients using the device.
The incidence of adverse reactions was significantly lower with the device (4.17%) compared to manual injection (13.9%).
The device completely eliminated ionizing radiation exposure for operators.

Conclusions:

The remote-controlled device offers a secure and effective alternative to manual contrast injection.
Controlled injection pressure (within 10 kPa) is key to its safety and efficacy.
The device is poised for clinical application in improving cholangiography procedures.
