23、 absolute criterion of performance is achieved by the combi- nation of the power-driven syringe pump and the syringe working as a complete system. The dependence of one element of the system on the performance of the other is a key factor. It is essential for the manufac- turer of one of these compo

24、nents to liaise with the manufacturer of the other when considering changes in design, in order to ensure satisfactory operation of the system. In particular, when requested by a pump manu- facturer, a syringe manufacturer should give information on tolerances and relationships between the syringe d

25、imensions specified in this part of IS0 7886 and on performance characteristics, such as force to move the plunger, and the variations which might be expected. 2 Design criteria The use of syringes which were initially designed and used as manually- operated devices in syringe pumps now makes it des

26、irable to achieve much tighter tolerances on syringe dimensions than normally required for manual use. It is understood that the degree of investment worldwide by all syringe manufacturers in moulding and manufacturing equipment is such that a change such as modifying diameters of push-buttons or th

27、e 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 particu- larly critical dimension. Its tolerances are ordinarily relatively loose. The hard-height dimension is a function of not only the total length of plu

28、nger rod and the barrel, but also the thickness of the piston and finger grips. The piston thickness, by virtue of its relatively unsophisticated manufacturing process, can vary considerably. Because all these components are manu- factured in multicavity moulds from many moulds around the world, the

29、 cumulative extreme tolerance buildup from cavity to cavity and mould to mould and location to location is such that these previously noncritical dimensions cannot be instantly tightened. 3 Syringe identification It is important that when a syringe is fitted to a syringe pump, the pump is correctly

30、programmed to perform satisfactorily with the particular syringe installed. In view of the consequences of incorrect syringe identification by the pump, the need for an automatic system is recognized. Methods already in use, such as mechanical sensing of the syringe outside diameter, are not deemed

31、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 outside and inside diameters of a syringe. It is also recognized that standardization of syringe barrel diameters across the industry is

32、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, plunger force and occlusion alarm settings is seen as the next stage of this part of IS0 7886. A possible method of recognition is to

33、 identify the syr- inge 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 pro- gramme the pump automatically. It is recommended that development of such a system be worked on as soon as possible. Page 4 EN IS0 7886-2 : 19

34、97 1 Scope This part of IS0 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-driven syringe pumps. This part of IS0 7886 does not apply to syringes for use with insulin (specified in

35、IS0 8537). single-use syringes made of glass (specified in IS0 5951, syr- inges prefilled with the injection by the manufacturer and syringes supplied with the injection as a kit for filling by a pharmacist. It does not address compati- bility with injection fluids. 2 Normative references The follow
