25、esign does not satisfy standards of electrical and mechanical safety. The EQUIPMENT may also cause danger to persons in the vicinity if the EQUIPMENT itself fails to contain the RADIOACTIVE SOURCE(S) adequately within the STORAGE CONTAINER(S) and/or if there are inadequacies in the design of the TRE

26、ATMENT ROOM. This Particular Standard establishes requirements to be complied with by MANUFACTURERS in the design and construction of AFTERLOADING EQUIPMENT for use in temporary BRACHY- THERAPY procedures; it does not attempt to define their optimum performance requirements. Its purpose is to identi

27、fy those features of design that are regarded, at the present time, as essential for the safe operation of such EQUIPMENT. It places limits on the degradation of EQUIPMENT performance beyond which it can be presumed that a fault condition exists and where an INTERLOCK then operates to return the RAD

28、IOACTIVE SOURCE(S) to the STORAGE CONTAINER(S) and afterwards to prevent continued operation of the EQUIPMENT. Page4 EN60601217:2004 MEDICAL ELECTRICAL EQUIPMENT Part 2-17: Particular requirements for the safety of automatically-controlled brachytherapy afterloading equipment SECTION ONE GENERAL The

29、 clauses and subclauses of this section of the General Standard apply except as follows: 1 Scope and object This clause of the General Standard applies except as follows: 1.1 Scope Addition: 1.1.101 This Particular Standard specifies requirements for the safety of automatically- controlled EQUIPMENT

30、 for BRACHYTHERAPY of patients using AFTERLOADING techniques. 1.1.102 This Standard specifies requirements for automatically-controlled AFTERLOADING EQUIPMENT which contains and uses only beta, gamma, and NEUTRON-emitting SEALED RADIOACTIVE SOURCES, which automatically drives the sealed radioactive

31、source(s) from a storage container to a treatment position inside the source applicator(s) and returns the source(s) to the storage container, which is designed for connection to a PATIENT, and with which movements of the RADIOACTIVE SOURCE(S) are carried out automatically by the EQUIPMENT according

32、 to a prescribed programme using a powered mechanism whose changes are controlled by the CONTROLLING TIMER(S) and TIMING DEVICES that are either PROGRAMMABLE ELECTRONIC SUB-SYSTEMS (PESS) (computer or microprocessors) or non-programmable systems. 1.1.103 This Standard specifies requirements for EQUI

33、PMENT intended to be used under the supervision of QUALIFIED PERSONS; maintained at predetermined intervals; subject to regular checks by the user. This Standard does not specify requirements for SEALED RADIOACTIVE SOURCES used with the EQUIPMENT. Such requirements are specified in other standards (

34、see 6.8.3). 1.1.104 The requirements of this Standard are based on the assumptions that: a TREATMENT PLAN is available that prescribes appropriate values of the TREATMENT PARAMETERS, and the SOURCE STRENGTH(S) of the RADIOACTIVE SOURCE(S) used by the EQUIPMENT is (are) known. Page5 EN60601217:2004 T

35、his Standard includes requirements intended to ensure that the prescribed values of the TREATMENT PARAMETERS can be achieved by the EQUIPMENT, in particular that: the selected RADIOACTIVE SOURCE(S) is (are) positioned or moved within the SOURCE APPLICATOR in the selected configuration relative to th

36、e SOURCE APPLICATOR; IRRADIATION is performed by the selected RADIOACTIVE SOURCE configuration for the selected duration; IRRADIATION is performed by the EQUIPMENT without causing unnecessary risk to the OPERATOR or other persons in the immediate surroundings. 1.2 Object Replacement: The object of t

37、his Particular Standard is to establish particular requirements for safety of automatically-controlled BRACHYTHERAPY AFTERLOADING EQUIPMENT and the compliance test specifications. It presents the general functional requirements of the demand for safety rather than particular technological means of i

38、mplementation. 1.3 Particular Standards ADDITION: 1.3.101 Relationship to the General Standard This Particular Standard is to be read in conjunction with IEC 60601-1:1988, Medical electrical equipment Part 1: General requirements for safety, with its Amendments 1 (1991) and 2 (1995) hereinafter refe

39、rred to as the General Standard which it amends and supplements. As in the General Standard, the requirements are followed by compliance tests. The numbering of sections, clauses and subclauses of this Particular Standard corresponds to that of the General Standard. The changes to the text of the Ge

40、neral and Collateral Standards are specified by the use of the following words: “Replacement“ means that the clause or subclause of the General Standard is replaced completely by the text of this Particular Standard; “Addition“ means that the text of this Particular Standard is additional to the req

41、uirements of the General Standard; “Amendment“ means that the clause or subclause of the General Standard is amended as indicated by the text of this Particular Standard. Subclauses, figures or tables which are additional to those of the General Standard are numbered starting from 101: additional an

42、nexes are lettered AA, BB, etc., and additional items aa), bb), etc. The term “this Standard “ is used to make reference to the General Standard and this Particular Standard taken together. Where there is no corresponding section, clause or subclause in this Particular Standard, the section, clause

43、or subclause of the General Standard, although possibly not relevant, applies without modification. Where it is intended that any part of the General Standard, although possibly relevant, is not to be applied, a statement to that effect is given in this Particular Standard. The requirements of this

44、Particular Standard take priority over those of the General Standard. Page6 EN60601217:2004 1.3.102 Relationship to other standards and documents NOTE See Appendix L for normative references. 1.5 Collateral Standards Addition: 1.5.101 IEC 60601-1-1 All clauses and subclauses of Collateral Standard I

45、EC 60601-1-1apply. 1.5.102 IEC 60601-1-2 All clauses and subclauses of Collateral Standard IEC 60601-1-2 apply. 1.5.103 IEC 60601-1-3 Collateral Standard IEC 60601-1-3 does not apply. 1.5.104 IEC 60601-1-4 All clauses and subclauses of Collateral Standard IEC 60601-1-4 apply. 2 Terminology and defin

46、itions This clause of the General Standard applies except as follows: Addition: For the purposes of this document, the terms and definitions given in the General Standard or in its Collateral Standards and the following apply. NOTE 1 The Index of defined terms at the end of this document lists defin

47、ed terms alphabetically with their source reference. NOTE 2 In this Particular Standard, IRRADIATION refers to the entire process of exposing the patient to RADIOACTIVE SOURCES in positions and for periods of time appropriate for TREATMENT. TRANSIT times are explicitly excluded from the TREATMENT TI

48、ME. NOTE 3 Although the actual titles of the persons fulfilling the following roles may vary from country to country, in this Particular Standard the term OPERATOR is used to denote the person controlling the BRACHYTHERAPY EQUIPMENT during treatment, and the term USER to denote the organization or i

49、ndividual responsible for the use and maintenance of the BRACHYTHERAPY AFTERLOADING EQUIPMENT. The terms radiotherapist and radiation oncologist, although not used in this Particular Standard, are used in many countries to denote the person exercising medical supervision and responsibility for determining and prescribing PATIENT treatment. 2.1 EQUIPMENT parts, auxiliaries and ACCESSO
