In referring to the structure of this standard, the term “clause” means one of the eight numbered divisions within the table of contents, inclusive of all subdivisions (e.g. Clause 8 includes Subclauses 8.1, 8.2, etc.); “subclause” means a numbere

21、d subdivision of a clause (e.g. 8.1, 8.2 and 8.2.1 are all subclauses of Clause 8). References to clauses within this standard are preceded by the term “Clause” followed by the clause number. References to subclauses within this standard are by number only. In this standard, the conjunctive “or” is

22、used as an “inclusive or” so a statement is true if any combination of the conditions is true.

Ne

37、 the BASIC SAFETY and ESSENTIAL PERFORMANCE of MEDICAL ELECTRICAL EQUIPMENT and MEDICAL ELECTRICAL SYSTEMS, hereafter referred to as ME EQUIPMENT and ME SYSTEMS. This collateral standard specifies requirements for the development (analysis, design, VERIFICATION and VALIDATION) of a PHYSIOLOGIC CLOSE

38、D-LOOP CONTROLLER (PCLC) as part of a PHYSIOLOGIC CLOSED-LOOP CONTROL SYSTEM (PCLCS) in ME EQUIPMENT and ME SYSTEMS to control a PHYSIOLOGIC VARIABLE. NOTE A PHYSIOLOGIC VARIABLE can be a body chemistry (e.g. electrolytes, blood glucose), a physical property (e.g. PATIENT temperature, electrophysiol

39、ogic, hemodynamic), or a pharmaceutical concentration. This collateral standard applies to various types of PCLC, e.g. linear and non-linear, adaptive, fuzzy, neural networks. This collateral standard does not specify: additional mechanical requirements; or additional electrical requirements. This c

40、ollateral standard applies to a closed-loop controller (see Figure 1) that sets the CONTROLLER OUTPUT VARIABLE in order to adjust (i.e., change or maintain) the measured PHYSIOLOGIC VARIABLE by relating it to the REFERENCE VARIABLE. A closed-loop controller that maintains a physical or chemical VARI

41、ABLE, using feedback that is not measured from a PATIENT, is outside the scope of this standard. 1.2 Object The object of this collateral standard is to specify general requirements that are in addition to those of the general standard and to serve as the basis for particular standards. 1.3 Related

42、standards 1.3.1 IEC 60601-1 For ME EQUIPMENT and ME SYSTEMS, this collateral standard complements IEC 60601-1. When referring to IEC 60601-1 or to this collateral standard, either individually or in combination, the following conventions are used: “the general standard“ designates IEC 60601-1 alone;

43、 “this collateral standard“ designates IEC 60601-1-10 alone; BS EN 60601-1-10:2008 7 Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 28/11/2008 01:56, Uncontrolled Copy, (c) BSI “this standard“ designates the combination of the general standard and this collateral standard. 1.3.2 Particular s
