OF-B188 Valve for PENTAX Endoscopes – Reliable Performance and Safe Maintenance
The PENTAX OF-B188 valve is an essential part of the gastrointestinal endoscopy system, ensuring both air insufflation and water washing of the distal lens of the endoscope. Designed for the 90i/90K series models, this valve plays a key role in ensuring image clarity and smooth endoscopic procedures. Thanks to its adapted design, it attaches easily to the endoscope and operates smoothly, provided that the O-rings are in good condition and properly lubricated.
Before each use, it is crucial to inspect the condition of the rubber seals. A valve that does not slide properly, feels "sticky" or offers unusual resistance must be removed, cleaned and lubricated with a small amount of silicone oil, applied with care so as not to clog the internal channels. Compliance with this maintenance protocol ensures the durability of the device and patient safety.
The OF-B188 is autoclavable, making it easy to integrate into standard sterilisation protocols in healthcare facilities. However, it must be sterilised at a high temperature before first use and after each procedure. If there is any doubt about its proper functioning – slow movement, a sticky feeling, or apparent damage – its use must be suspended. It is recommended to have a spare O-ring kit available, which must be subjected to high-level disinfection or prior sterilisation.
Failure to follow these instructions could result in cross-contamination or excessive insufflation, with a potential risk of perforation. For this reason, constant vigilance is essential. The OF-B188 valve is the tool of choice for professionals who demand reliability, precision and safety on a daily basis.
It is therefore an essential component for maintaining the optical performance and safety of endoscopic procedures, while meeting the strict sterilisation and traceability requirements of hospital environments.
