1、Designation:F 1195 99Standard Specification forRigid Laryngoscopes for Tracheal IntubationHook onFittings for Fiberilluminated Blades and Handles1This standard is issued under the fixed designation F 1195;the number immediately following the designation indicates the year oforiginal adoption or,in t
2、he 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.INTRODUCTIONIn clinical anesthesia and resuscitation a variety of laryngoscopes are used.Because ther
3、e is aclinical need for a variety of blade forms,they are manufactured as detachable blade and handle units.In the interest of patient safety,defined dimensions and performance standards are necessary.The aimof this specification is to ensure compatibility of rigid,folding,fiber-illuminated blades a
4、nd handleswithin a given system without restricting innovation or design.1.Scope1.1 The purpose of this specification is to ensure thatreusable,detachable fiber-illuminated hook-on blade andhandle combinations that engage shall lock and illuminatewhen in the operating position.1.2 Dimensions and tol
5、erances of fiber-illuminated systemsshall be provided.1.3 This specification provides methods of identifying bycolor the various fiber-illuminated systems and compatibleblades and handles within the system.1.4 This specification covers reusable handles and blades.Itdoes not cover disposable componen
