1、Designation:F 1518 00Standard Practice forCleaning and Disinfection of Flexible Fiberoptic and VideoEndoscopes Used in the Examination of the Hollow Viscera1This standard is issued under the fixed designation F 1518;the number immediately following the designation indicates the year oforiginal adopt
2、ion or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon(e)indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice covers the flexible fiberoptic and videoendoscopes that are fully
3、 immersible in liquid and are used inthe examination of the hollow viscera(that is,colonoscopes,gastroscopes,duodenoscopes,sigmoidoscopes,and entero-scopes).These endoscopes will be referred to as flexiblegastrointestinal(GI)endoscopes.1.1.1 It is strongly recommended that only immersibleendoscopes
4、be used in order to assure that all parts of theendoscope will be high-level disinfected;however,it is recog-nized that,in some instances,portions of endoscopes thatneither contact patients nor patient fluids may not be immers-ible.In these instances,care must be taken to disinfect thenonimmersible
5、portions to the highest degree with which theyare compatible,according to the manufacturers directions.1.2 This practice is intended to complement,not replace theinstructions and labeling provided by product manufacturers.Endoscope manufacturers must provide instructions and label-ing necessary for
6、users to know the basic design,specifications,nomenclature,and components of specific flexible GI endo-scopes and to properly inspect,prepare,use,clean,disinfect,rinse,dry,and store these instruments.1.3 Endoscopic technique and the medical aspects of gas-trointestinal endoscopy are not covered in t
7、his practice.1.4 This practice details the steps necessary to properlyreprocess flexible GI endoscopes and render them patient-ready.1.5 This practice details manual reprocessing as well asautomated reprocessing of flexible GI fiberoptic and videoendoscopes.1.6 The application of all practices relat
8、ing to endoscopicreprocessing will ultimately fall into the purview of theindividual assigned to that task in an endoscopic area.1.6.1 To ensure the proper adherence to this practice,thosepersonnel should themselves meet certain requirements asspecified in 4.8.1.7 This practice does not detail the s
9、teps necessary for thereprocessing of endoscopic accessories.1.8 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bil
10、ity of regulatory limitations prior to use.Specific precau-tionary statements are given in Note 1 and Note 2.2.Terminology2.1 Definitions of Terms Specific to This Standard:2.1.1 clean,adjvisibly free from debris.2.1.2 endoscope,nflexible GI endoscope,flexible fiberop-tic or video endoscopes used in

12、micide,which has passed the AOAC sporicidaltest with no failures;therefore,to qualify for a high-leveldisinfection claim,a germicide must be a sterilant as defined bythe AOAC sporicidal test.In addition,the claim should besupported by efficacy data from potency tests,simulated-usetests,and in-use te

15、-stances,portions of an endoscope that neither contact patientfluids nor contact the patient directly,may not be immersible(for example,ultrasound endoscopes).In these instances,caremust be taken to disinfect the non-immersible portions of theendoscope to the highest degree with which they are compa
