The Olympus MH‑443 is a precision suction valve designed for Olympus EVIS 140/160 series endoscopes, providing fingertip control of suction to clear fluids, mucus, and blood while maintaining visualization during GI, pulmonary, and other flexible endoscopy procedures. This reusable component fits into the endoscope’s suction cylinder and is intended to be cleaned and high‑level disinfected or sterilized between cases according to Olympus reprocessing guidelines.
