A simple pressure injector for contrast material

Area of Science:

• Medical Devices
• Radiology
• Interventional Procedures

Background:

• Intravenous contrast material administration is crucial for various diagnostic imaging procedures.
• Current pressure injection methods can be complex or expensive.

Purpose of the Study:

• To describe a novel, low-cost method for pressure-assisted contrast material injection.
• To evaluate the feasibility and safety of using a modified caulking gun for this purpose.

Main Methods:

• A standard carpenter's caulking gun was modified for use as a pressure injector.
• Intravenous infusions of contrast material were performed using small caliber needles.
• Ease of use, safety, and effectiveness were qualitatively assessed.

Main Results:

• The modified caulking gun facilitated controlled intravenous infusion of contrast material.
• The procedure was performed with relative ease and perceived safety.
• Small caliber needles were effectively utilized for contrast delivery.

Conclusions:

• A carpenter's caulking gun can serve as a practical and affordable pressure injector for intravenous contrast administration.
• This method offers a potentially simpler and safer alternative for certain clinical scenarios.
