15、he International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical commit

16、tee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotech

17、nical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member

18、 bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying

19、 any or all such patent rights. ISO 14708-4 was prepared by Technical Committee ISO/TC 150, Implants for surgery, Subcommittee SC 6, Active implants. ISO 14708 consists of the following parts, under the general title Implants for surgery Active implantable medical devices: Part 1: General requiremen

20、ts for safety, marking and for information to be provided by the manufacturer Part 2: Cardiac pacemakers Part 3: Implantable neurostimulators Part 4: Implantable infusion pumps ISO 14708-4:2008(E) vi ISO 2008 All rights reservedIntroduction This part of ISO 14708 specifies particular requirements fo

21、r active implantable medical devices intended to deliver a medicinal substance to site-specific locations within the human body, to provide basic assurance of safety for both patients and users. It amends and supplements ISO 14708-1:2000, hereinafter referred to as ISO 14708-1. The requirements of t

22、his part of ISO 14708 take priority over those of ISO 14708-1. An implantable infusion pump is a device that delivers either a constant flow rate or a variable flow rate from which a medicinal substance is delivered via an implanted catheter to site-specific locations within the human body. An exter

23、nal programmer might be used to adjust device parameters. This part of ISO 14708 is relevant to all parts and accessories of implantable infusion pumps, including catheters, refill kits, direct access port kits, programmers and related software. Not all parts or accessories might be intended to be t

24、otally or partially implanted, but there is a need to specify some requirements of non- implantable parts and accessories if they could affect the safety or performance intended by the manufacturer. Requirements for physiologic sensing functions of implantable infusion pumps are not included in this

25、 edition of this part of ISO 14708 but might be considered in future editions. Within this part of ISO 14708 the following terms are used to amend and supplement ISO 14708-1: “Replacement”: the clause of ISO 14708-1 is replaced completely by the text of this particular part of ISO 14708. “Addition”:

26、 the text of this particular part of ISO 14708 is additional to the requirements of ISO 14708-1. “Amendment”: the clause of ISO 14708-1 is amended as indicated by the text of this particular part of ISO 14708. “Not used”: the clause of ISO 14708-1 is not applied in this particular part of ISO 14708.

27、 Subclauses, figures, or tables that are additional to those of ISO 14708-1 are numbered starting from 101; additional annexes are lettered AA, BB, etc. INTERNATIONAL STANDARD ISO 14708-4:2008(E) ISO 2008 All rights reserved 1 Implants for surgery Active implantable medical devices Part 4: Implantab

28、le infusion pumps 1 Scope This part of ISO 14708 is applicable to active implantable medical devices intended to deliver medicinal substances to site-specific locations within the human body. This part of ISO 14708 is also applicable to some non-implantable parts and accessories of the devices as de

29、fined in Clause 3. The tests that are specified in this part of ISO 14708 are type tests intended to be carried out on a sample of a device to show compliance, and are not intended to be used for the routine testing of manufactured products. NOTE This part of ISO 14708 is not intended to apply to no

30、n-implantable infusion systems. However, it does apply to devices intended to be used as trial systems because of their close affiliation with implantable infusion pumps. 2 Normative references The following referenced documents are indispensable for the application of this document.

35、 implantable medical device intended for delivery of a medicinal substance to a specific location within the human body NOTE For purposes of this part of ISO 14708, an implantable infusion pump can be a single article, or a system consisting of a set of components and accessories which interact to a

Not all of these components or accessories might be required to be partially or totally implanted, e.g. programmers and trial systems. 3.102 pump gear implantable part of an implantable infusion pump containing the fluid reservoir, energy source a

41、h the same implantable infusion pump with the same infusate under the same conditions can be expected to lie, with a probability of 95 % NOTE 1 A more qualitative way of looking at repeatability is the ability to consistently deliver the same results over time (e.g. infusion rate). Repeatability is

42、a metric independent of accuracy.

Environmental test conditions used to establish infusion accuracy shall also be stated. NOTE 2 Accuracy is a commonly used term and

49、 might include the effects of systematic and random errors. Although it is convenient to combine all these errors under the heading “accuracy”, it is still a qualitative term. For all selectable infusion rates, the repeatability of the actual rate shall also be stated. The method of computing and determining the stated repeatability shall be clearly described in the accompanying documentation. Compliance shall be confirmed by inspection of test procedures and results provided by the manufacturer, supp
