The insufflation bulb for pneumatic testing is a specialized device designed for assessing the integrity and functionality of various medical instruments, such as endoscopes and surgical tools, that require an insufflation system. This bulb serves as a manual insufflator, allowing healthcare professionals to precisely control and regulate the flow of gas into the instrument or body cavity being tested. The bulb is typically connected to the instrument via a tubing system, and by squeezing and releasing the bulb, the user can create a controlled stream of air or carbon dioxide for insufflation purposes. This pneumatic testing is crucial in ensuring that medical equipment functions as intended, maintaining optimal performance and patient safety during diagnostic and therapeutic procedures. The insufflation bulb for pneumatic testing exemplifies a simple yet indispensable tool in the meticulous quality control processes within the medical field.
