25、). 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 committee has been established has the right to be represented on that committee. International organizations, governmental and no
26、n-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies
27、 for voting. Publication as an International Standard requires approval by at least75% of the member bodies casting a vote. International Standard ISO 7886-2 was prepared by Technical Committee ISO/TC 84, Medical devices for injections, Subcommittee SC 1, Syringes, needles and intravascular catheter
28、s for single use. ISO 7886 consists of the following parts, under the general title Sterile hypodermic syringes for single use: Part 1: Syringes for manual use; Part 2: Syringes for use with power-driven syringe pumps. Annex A, Annex B and Annex C form an integral part of this part of ISO 7886. Anne
29、x D and Annex E are for information only. ISO 7886 was first published in 1984. It was subsequently decided to divide it into two parts, ISO 7886-1 retaining essentially the scope of ISO 7886:1984, andISO 7886-2 being applicable to sterile, single-use syringes for use with power-driven pumps.iv blan
30、kBSENISO7886-2:1997 BSI 04-2000 1 Introduction 1 General In the preparation of this part of ISO 7886, it was recognized at an early stage that the absolute criterion of performance is achieved by the combination of the power-driven syringe pump and the syringe working as a complete system. The depen
31、dence of one element of the system on the performance of the other is a key factor. It is essential for the manufacturer of one of these components to liaise with the manufacturer of the other when considering changes in design, in order to ensure satisfactory operation of the system. In particular,
32、 when requested by a pump manufacturer, a syringe manufacturer should give information on tolerances and relationships between the syringe dimensions specified in this part of ISO 7886 and on performance characteristics, such as force to move the plunger, and the variations which might be expected.
33、2 Design criteria The use of syringes which were initially designed and used as manually-operated devices in syringe pumps now makes it desirable to achieve much tighter tolerances on syringe dimensions than normally required for manual use. It is understood that the degree of investment worldwide b
34、y all syringe manufacturers in moulding and manufacturing equipment is such that a change such as modifying diameters of push-buttons or the barrel inside diameter is largely out of reach of the syringe industry. Typically the hard height of a syringe has never been regarded as a particularly critic
35、al dimension. Its tolerances are ordinarily relatively loose. The hard-height dimension is a function of not only the total length of plunger rod and the barrel, but also the thickness of the piston and finger grips. The piston thickness, by virtue of its relatively unsophisticated manufacturing pro
36、cess, can vary considerably. Because all these components are manufactured in multicavity moulds from many moulds around the world, the cumulative extreme tolerance buildup from cavity to cavity and mould to mould and location to location is such that these previously noncritical dimensions cannot b
37、e instantly tightened. 3 Syringe identification It is important that when a syringe is fitted to a syringe pump, the pump is correctly programmed to perform satisfactorily with the particular syringe installed. In view of the consequences of incorrect syringe identification by the pump, the need for
38、 an automatic system is recognized. Methods already in use, such as mechanical sensing of the syringe outside diameter, are not deemed feasible in the long term. This is due to overlapping ranges of diameter of syringes produced by different manufacturers, and the lack of relationship between the ou
39、tside and inside diameters of a syringe. It is also recognized that standardization of syringe barrel diameters across the industry is not a realistic option. A means by which the pump could automatically identify the syringe model and use this to programme such information as barrel inside diameter
40、, plunger force and occlusion alarm settings is seen as the next stage of this part of ISO7886. A possible method of recognition is to identify the syringe and nominal capacity by means of a marking code on the barrel, printed at the same time as the syringe scale, and to use this to programme the p
41、ump automatically. It is recommended that development of such a system be worked on as soon as possible. 1 Scope This part of ISO 7886 specifies requirements for sterile single-use hypodermic syringes of nominal capacity 5 ml and above, made of plastics materials and intended for use with power-driv
42、en syringe pumps. This part of ISO 7886 does not apply to syringes for use with insulin (specified in ISO 8537), single-use syringes made of glass (specified in ISO 595), syringes prefilled with the injection by the manufacturer and syringes supplied with the injection as a kit for filling by a phar
43、macist. It does not address compatibility with injection fluids. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO7886.
