The Olympus MH-946 injection tube: professional standards for safety
Designed to meet the most stringent hospital hygiene requirements, the Olympus MH-946 injection tube is the go-to accessory for reprocessing TJF-Q180V flexible endoscopes. This tool ensures precise and controlled injection of cleaning, disinfecting and rinsing fluids into the critical channels of the endoscope, namely the instrumentation, suction and air/water channels.
The main role of the MH-946 is to ensure that the internal channels of endoscopes are thoroughly irrigated and free of all biological and chemical residues before and after each clinical procedure. Thanks to its various ports and connected tubes, it also allows residual liquids to be expelled via a controlled air injection, thus limiting the risk of microbial growth or internal corrosion.
This device has a functional architecture consisting of several clearly identifiable segments: a tube for the suction channel, another for the air/water channel, a suction port, an air/water port, and a connector for a 30 mL manual syringe. An integrated mesh filter provides additional safety by retaining unwanted particles while allowing fluids to pass through efficiently.
Beyond its primary function, the MH-946 embodies a standard of reliability. It has been specifically validated for use with manual and automated disinfection protocols, while complying with Olympus' material compatibility standards. During each reprocessing session, it plays a pivotal role in ensuring the integrity of medical equipment while limiting the risk of pathogen transmission between patients.
It is part of a preventive maintenance programme for endoscopic equipment: proper use of the MH-946 actively helps to optimise the service life of the endoscope by preventing the accumulation of deposits or stagnation of liquids in the internal ducts. It is therefore an essential link in the endoscopy safety chain, both for the patient and for the equipment.
