NOTE:

Flexible endoscopes and other sophisticated medical instruments are constructed

of special materials, unique parts and intricate components with strict dimensional

tolerances.Specializedassemblytechniquesandapplicationofspecicsealants

and/or adhesives are required to ensure the watertight integrity and maintain the

functionality of these devices. It is therefore imperative that endoscopes be routinely

checked to ensure that parts used in their construction are not loose, missing or

compromised that could otherwise negatively affect the functionality of these devices.

Compromised or loose components could result in device failure, endoscope damage

(viauidinvasion)and/orinincompletedecontaminationofusedinstruments.

PENTAX recommends that prior to use endoscopes should be carefully inspected for

their integrity and checked for any “looseness” in the mating or joining of components

including the following parts/areas:

●channel inlet assembly (biopsy inlet port) (1)

●suction/irrigation nipple/connector (2)

●suction/irrigation valve cylinder (3)

●venting connector (4)

●basically, any inlet or outlet port associated with an internal channel, an indirect

patient contact portion of the endoscope

●rubber strain relief along insertion tube and umbilical cable (rotate clockwise only

to tighten)

(1)

Figure 2.8

One method to check for looseness is to lightly grip the exposed part, and while

grasping the component carefully attempt to move it in various directions. Use of a

lint-free gauze while grasping metal parts is recommended as a protection for one’s

ngers.

If any part/component remains loose (after attempting to tighten) and/or if there is any

indication or suspicion of an abnormality or outward signs of damage, do NOT use

the endoscope. Contact your local PENTAX service facility.
