Researchers have developed a prototype CO2 insufflator that when used during a colonoscopy reduces the discomfort caused by the procedure. The technology developed through this project could provide a disposable CO2 insufflator that uses an effervescent reaction to generate CO2 and is compatible with standard flexible endoscopes. Effervescent chemical reactions are one of the few physical phenomena capable of safely generating biocompatible gases in a rapid manner. This ability enables the development of this technology for providing surgical insufflation through small, light-weight and disposable devices that can be used safely in standard clinical settings, remote locations and frontline triage units.Currently used CO2 insufflators are large, complex and not widely used due to the high costs associated with the equipment. Development of a small, disposable CO2 insufflator could increase regular use of CO2 insufflators during colonoscopy procedures, which in turn would reduce the discomfort experienced by the patient during the procedure. This technology could enable a new class of insufflators which can be used in a wide range of minimally invasive procedures.

研究人员已经开发出一种原型CO2吹入器，当在结肠镜检查过程中使用时，可以减少手术引起的不适。通过该项目开发的技术可以提供一种一次性CO2吹入器，该吹入器使用二氧化碳反应产生CO2，并与标准软式内窥镜兼容。泡腾化学反应是能够以快速的方式安全地产生生物相容性气体的少数物理现象之一。这种能力使得该技术的发展成为可能，通过小型、轻质和一次性设备提供外科注气，这些设备可以安全地用于标准临床环境、偏远地区和前线分诊单位。目前使用的CO2注气器体积大、结构复杂，并且由于与设备相关的高成本而未被广泛使用。小型一次性CO2吹入器的开发可以增加结肠镜检查过程中CO2吹入器的定期使用，这反过来又会减少患者在检查过程中的不适。这项技术可以使一类新的吹入器，可用于广泛的微创手术。
