25、86 was recognized as a high priority requirement to prevent the re-use of syringes in the developing and transitional countries. Re-use of injection equipment in the absence of sterilization has increasingly led to transmission of blood-borne pathogens. See Reference 1 in the Bibliography. The World
26、 Health Organisation had produced a specification for syringes that are rendered inactive after use (commonly referred to as “auto-disable” syringes) for fixed dose immunization and syringes with re-use prevention features for general purpose. Both the WHO and ISO agreed that additional parts of ISO
27、 7886 would be required to cover syringes with re-use prevention features, whilst leaving in place ISO 7886-1 and ISO 7886-2 without modification, as a large number of devices in common use would not be intended to comply with the re-use prevention properties suggested. This part of ISO 7886 is inte
28、nded to cover syringes that are rendered inoperable after delivery of the intended dose. These syringes are not covered by ISO 7886-1 and ISO 7886-3. ISO 7886-2 covers syringes used with power-driven pumps. Given the diversity of clinical applications, the most appropriate re-use prevention feature
29、offering the highest level of re-use prevention is to be considered for each specific intended use. It is recognized that syringes designed to reduce the risk of needlestick injuries can also comply with this part of ISO 7886 with regard to their re-use prevention properties, but it is stressed that
30、 anti-needlestick properties of syringes are not in themselves addressed in this part of ISO 7886. 4 DIN EN ISO 7886-4:2010-01 EN ISO 7886-4:2009 (E) 1 Scope This part of ISO 7886 specifies requirements for sterile single-use hypodermic syringes made of plastics materials with or without needle, and
31、 intended for the aspiration of fluids or for the injection of fluids immediately after filling and of design such that the syringe can be rendered unusable after use. This part of ISO 7886 is not applicable to syringes made of glass (specified in ISO 595), auto-disable syringes for fixed dose immun
32、ization (ISO 7886-3) and syringes designed to be pre-filled. It does not address compatibility with injection fluids. Other standards can be applicable when syringes are used for any other intended purpose than those specified in this part of ISO 7886. NOTE Syringes designed to reduce the risk of ne
33、edlestick injuries can also comply with this part of ISO 7886 with regard to their re-use prevention properties, but it is stressed that anti-needlestick properties of syringes are not in themselves addressed in this part of ISO 7886. 2 Normative references The following referenced documents are ind

38、e or is activated by the user to prevent subsequent re-use of the syringe 4 Nomenclature The nomenclature for components of syringes with re-use prevention feature is shown in Figure 1. 5 Types of syringe 5.1 General Syringe types shall be categorized in accordance with 5.2 and 5.3. Given the divers
39、ity of clinical applications, the most appropriate re-use prevention feature offering the highest level of re-use prevention should be considered for each specific intended use. 5.2 Re-use prevention feature The re-use prevention feature shall be categorized as follows; Type 1: operates automaticall
40、y during or upon completion of intended single use; Type 2: requires elective activation upon completion of intended single use. 5.3 Intended use/application The intended use/application shall be categorized as follows; Type A: single aspiration and injection; Type B: multiple plunger aspirations pr
41、ior to the final intended single use. 6 Cleanliness The requirements of Clause 5 of ISO 7886-1:1993 apply. 7 Limits for acidity or alkalinity When determined with a laboratory pH meter and using a general purpose electrode, the pH value of an extract prepared in accordance with Annex A shall be with
42、in one unit of pH of that of the control fluid. 8 Limits for extractable metals When tested by a recognized microanalytical method, for example by an atomic absorption method, an extract prepared in accordance with Annex A shall, when corrected for the metals content of the control fluid, contain no
43、t greater than a combined total of 5 mg/l of lead, tin, zinc and iron. The cadmium content of the extract shall, when corrected for the cadmium content of the control fluid, be lower than 0,1 mg/l. 6 DIN EN ISO 7886-4:2010-01 EN ISO 7886-4:2009 (E) Key 1 needle cap/protective end cap (if used) 2 nee
