MAJ-1443: a Suction Valve for Controlled and Reliable Aspiration
The MAJ-1443 is a suction valve designed by Olympus for use in high-precision ultrasonic endoscopy systems, particularly with the GF-UCT180 ultrasonic gastrovideoscope. This valve plays a crucial role in fluid management during endoscopic examinations, facilitating both general suction and targeted drainage of fluids, including those from the balloon used for ultrasound imaging.
This device is distinguished by its dual functionality: partial pressure on the valve activates standard suction through the operating channel, allowing the endoscope's field of view to be cleaned or secretions to be removed. Full pressure on the valve triggers suction through the balloon channel, ensuring the effective removal of sterile water injected into the ultrasound balloon. This differentiated mechanism avoids multiple manipulations and limits the risk of cross-contamination or handling errors.
Its design has been carefully thought out to fit perfectly into the suction cylinder of the endoscope. During installation, it is important to ensure that the silicone skirt of the valve is not wrinkled or misaligned. A poorly fitted valve can result in ineffective suction or fluid leakage, compromising both the practitioner's visibility and patient safety.
The MAJ-1443 is a consumable item for regular use, which means that it must be thoroughly inspected before each procedure. Any visible abnormalities (deformation, cracks, stiffness, abnormal noise during dry suction) require immediate replacement. It does not require lubrication before use, as the addition of lubricants could damage the internal seals and impair its proper functioning.
By integrating the MAJ-1443 into the endoscopy circuit, the practitioner benefits from precise and intuitive control, promoting a smooth, fast and safe procedure in accordance with hospital hygiene protocols. This valve is therefore a discreet but strategic element in the reliability chain of a successful endoscopic procedure.
