一些非侵入性器械不与身体直接接触但可以影响生理过程(通过血液、其他体液或重新吸收或注入体内的液体的转化、引流、处理或者输入体内的能量转换的方式来实现)。
这些器械不适用于以上规则,因为他们本身对身体有潜在的危害
Rule2-Channelingorstoringforeventualadministration
规则2最终用于药控的导引或存储
Generalexplanationoftherule
规则简述
Thesetypesofdevicesmustbeconsideredseparatelyfromthenon-contactdevicesofrule1becausetheymaybeindirectlyinvasive.Theychannelorstoresubstancesthatwillbeeventuallydeliveredintothebody.Typicallythesedevicesareusedintransfusion,infusion,extracorporealcirculation,deliveryofanaestheticgasesandoxygen.
这类器械应与规则1所述的非接触性器械分开来因为他们可能不直接侵入。
他们引导或存储那些最终会注入人体的物质,典型产品:
用于转运,注射,体外循环,投递麻醉气体或的器械。
Insomecasesdevicescoveredunderthisruleareverysimplegravityactivateddeliverydevices.
有些情况下,这条规则所属的器械仅仅是重力源性投递器械
RULE2

-iftheymaybeconnected1toanactivemedicaldeviceinClassIIaorahigherclass,用于引导或储存血液、体液或人体或人体组织、液体或气体供最终注入、施入或导入人体的所有非侵入性器械。
如果他们可以连接Ⅱ类或更高级别的有源医疗器械则其属于Ⅱa类
-Devicesintendedtobeusedaschannelsinactivedrugdeliverysystems,e.g.tubingintendedforusewithaninfusionpump.-Devicesusedforchanneling,e.g.antistatictubingforanesthesia,anesthesiabreathingcircuitsandpressureindicator,pressurelimitingdevices.-Syringesforinfusionpumps.

-仅仅是利用重力来导引液体如(注射滴瓶)
-暂时包裹或储存用的器械如(管制药物杯、勺)
-无针耳咽管
Bloodbagsarecoveredasanexceptionunderaseparaterule(seerule18).
血袋是例外(参见规则18)
Ifadevice,e.g.tubing,canbeusedforapurposethatwouldcauseittobeconnectedtoanactivedevicesuchadevicewillbeautomaticallyinClassIIA,unlessthemanufacturerclearlystatethatitshouldnotbeconnectedtoanactivedeviceofClassIIAorhigher.
如果一种器械比如管子与有源器械相连而发挥作用,则这种器械自动归于Ⅱa类,除非制造商明确规定其不与Ⅱa类或者更高级别的器械连用。
Explanationofspecialconcepts
专业术语解释
Note1:
"
Maybeconnectedtoanactivedevice"
.Suchconnectionisdeemedtoexistbetweenanon-activedeviceandanactivedevicewhereanon-activedeviceformsalinkinthetransferofthesubstancebetweenthepatientandtheactivedeviceandthesafetyandperformanceofoneofthedevicesisinfluencedbytheotherdevice.Forinstance,thisappliestotubinginanextracorporealcirculationsystemwhichisdownstreamfromabloodpumpandinthesamebloodflowcircuit,butnotdirectlyincontactwiththepump.
“与有源器械相连”指的是这种器械存在与无源和有源器械之间,而无源器械起到连接病人和有源器械物质转运的纽带作用且他们之间的安全性和性能互相影响制约。
比如,存在于血泵下游和血流循环之间但并不和血泵直接相连的体外循环系统的管子。
Note2:
Solutionsintendedforpreservationoforgansduringstorageandtransportarenotmedicaldevices.
用于储存和移植期间保护器官的溶液不属于医疗器械
Rule3-Devicesthatmodifybiologicalorchemicalcompositionofblood,bodyliquidsorotherliquids

这类器械应与规则1所述的非接触性器械分开来因为他们不直接侵入人体。
他们处理或改变那些最终会注入人体的物质。
这条规则涵盖了大多数的更专业化的体外循环元件、透析系统、自体循环系统以及那些可能或者可能不立即注入进人体的体外体液处理设备,包括那些使病人不处于这些封闭式循环器械之内的器械。

过滤和离心在这条中应被理解为单一的机械方法
Rule4-Devicesincontactwithinjuredskin
与受伤皮肤接触的器械
Thisruleisintendedtocoverprimarilywounddressingsindependentlyofthedepthofthewound.Thetraditionaltypesofproducts(e.g.usedasamechanicalbarrier)arewellunderstoodanddonotresultinanygreathazard.Therehavealsobeenrapidtechnologicaldevelopmentsinthisarea,withtheemergenceofnewtypesofwounddressingsforwhichnon-traditionalclaimsaremade,e.g.managementofthemicro-environmentofawoundtoenhanceitsnaturalhealingmechanism.Moreambitiousclaimsrelatetothemechanismofhealingbysecondaryintent,suchasinfluencingtheunderlyingmechanismsofgranulationorepithelialformationorpreventingcontractionofthewound.Somedevicesusedonbreacheddermismayevenhavealife-sustainingorlife-savingpurpose,e.g.whenthereisfullthicknessdestructionoftheskinoveralargeareaand/orsystemiceffect.DressingscontainingmedicinalproductsactingasancillarytothedressingfallwithinClassIIIunderRule13.
这条规则主要适用于那些主要是用于独立作用于伤口深度的伤口敷料,传统的产品种类如:
用作机械屏障,很容易让人明白而且不产生任何危险。
这个领域技术发展迅速,出现了许多非传统的伤口敷料,如可控制伤口微环境以有利于伤口恢复的敷料。
也出现了许多对二次恢复有效的敷料,如影响肉芽生长、上皮重建、防止伤口收缩用的伤口敷料。
有的用于伤及真皮的敷料可以挽救、支持生命,如大面积全程毁坏或系统性影响。
含有药物成分的敷料起到辅助作用按照规则13则归属于三类
