A versatile dual-channel carbon dioxide (CO2) insufflator for various CO2)applications. The prototype

Area of Science:

• Medical Devices
• Gastroenterology
• Surgical Technology

Background:

• Carbon dioxide (CO2) is a superior insufflating agent to air due to rapid absorption.
• Lack of suitable feeding systems has limited widespread clinical adoption of CO2.
• A novel dual-channel CO2 insufflator has been developed to address this limitation.

Purpose of the Study:

• Introduce a prototype dual-channel CO2 insufflator.
• Evaluate the safety and performance of the CO2 insufflator.
• Validate the application of CO2 insufflation using the prototype device.

Main Methods:

• A prototype dual-channel CO2 insufflator with independent conduits for controlled and manual insufflation was designed.
• The device was tested using canine models.
• Simultaneous CO2 pneumoperitoneum and CO2 colonoscopy were performed.

Main Results:

• The prototype demonstrated safe and effective performance without malfunctions.
• CO2 colonoscopy was feasible concurrently with CO2 pneumoperitoneum.
• Intraluminal CO2 insufflation resulted in less residual intestinal gas compared to air insufflation.

Conclusions:

• The dual-channel CO2 insufflator facilitates simultaneous, independent CO2 insufflation modes from a single cylinder.
• The device shows promise for safer and broader application of CO2 in clinical settings.
• Further improvements are underway to enhance the prototype for wider operating room use.
