WATER BOTTLE ASSEMBLY OS-H4
1. INTENDED USE
The PENTAX water bottle assembly, OS-H4 is- intended to be used with compatible PENTAX flexible endoscopes and
PENTAX air sources (video processor, light source, etc.) for delivery of air and/or water during endoscopic procedures.
NEVER use the water bottle for any purpose other than that for which it has been designed.
Since endoscopic accessories, including the water bottle are designed to be used in conjunction with other medical devices,
the effectiveness of an accessory especially a reusable one, is dependent upon a number of factors, including the condition of
the endoscope and the care and maintenance of the accessory and related devices.
WARNING:
The water bottle assembly identified in this manual is a reusable medical device. Since it is packaged nonsterile, it must
be sterilized BEFORE initial patient use. Subsequently, it should be subjected to an appropriate cleaning and sterilization
process at least on a daily basis or more frequently depending upon the patient and/or type of endoscopic procedure.
2. NOMENCLATURE
NOTE:
If the water bottle assembly has been handled roughly, the water feeding tube inside the hose may be damaged or
disconnected at the A/W connector for the endoscope. To test, remove the cap and using a syringe, inject water into the
water feeding stem. If the water comes out of both the center hole of the A/W connector and the series of holes around
the center hole, the water feeding tube is disconnected. Use another water bottle assembly.
3. DIRECTIONS FOR USE
1) Fill the bottle approximately 2/3 full with sterile water.
2) Screw the bottle cap snugly onto the bottle.
NOTE:
Do NOT use the new PENTAX OS-H4 water bottle cap with the older OS-H2 water container/bottle. Although the cap
may appear to fit onto the bottle, air may escape resulting in insufficient pressure and flow of air and water during the
endoscopic procedure. Both the PENTAX water bottle cap and bottle (container) are identified by their appropriate
model designation. Ensure that an OS-H4 cap is used only with the OS-H4 water container/bottle.
Do NOT over-tighten the bottle cap. Over-tightening can cause the bottle cap to break.
3) Set the Air/Water - Drain lever to A/W position.
4) Insert the air pipe stem into the processor or light source and press until the water bottle ‘clicks’ into position.
