28、O 8637:2014-03EN ISO 8637:2014 (E)Introduction This International Standard is concerned with devices intended for haemodialysis, haemodiafiltration, haemofiltration and haemoconcentration in humans. The requirements specified in this International Standard will help to ensure safety and satisfactory
29、 function. It was not found practicable to specify materials of construction. This International Standard therefore requires only that materials have been tested and that the methods and results are made available upon request. There is no intention to specify, or to set limits on, the performance c
30、haracteristics of the devices because such restrictions are unnecessary for the qualified user and would limit the alternatives available when choosing a device for a specific application. The dimensions of the blood ports and the dialysis fluid or filtrate ports have been specified to ensure compat
31、ibility of the device with the extracorporeal blood circuit specified in ISO 8638. The design and dimensions have been selected in order to minimize the risk of leakage of blood and the ingress of air. This International Standard reflects the consensus of physicians, manufacturers and other interest
32、ed parties for devices that are approved for clinical use. Conformance with this International Standard is voluntary and it does not supersede any national regulation. 4DIN EN ISO 8637:2014-03 EN ISO 8637:2014 (E) 1 Scope This International Standard specifies requirements for haemodialysers, haemodi
33、afilters, haemofilters and haemoconcentrators, hereinafter collectively referred to as “the device”, for use in humans. This International Standard is not applicable to: extracorporeal blood circuits; plasmafilters; haemoperfusion devices; vascular access devices; blood pumps; pressure monitors for
34、the extracorporeal blood circuit; air detection devices; systems to prepare, maintain or monitor dialysis fluid; systems used to perform haemodialysis, haemodiafiltration, haemofiltration or haemoconcentration; reprocessing procedures and equipment. NOTE Requirements for the extracorporeal blood cir
35、cuit for haemodialysers, haemodiafilters and haemofilters are specified in ISO 8638. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of t

38、toxicity 5DIN EN ISO 8637:2014-03EN ISO 8637:2014 (E)3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 blood compartment part of a haemodialyser (3.12), haemodiafilter (3.10), haemofilter (3.14) or haemoconcentrator (3.9) through which blood is
39、 intended to pass NOTE For hollow-fibre devices, the blood compartment includes the volume of the hollow fibres plus the headers. 3.2 clearance volume of a solution from which a solute is completely removed per unit time 3.3 convection transport of solutes across a semipermeable membrane, along with
40、 filtered fluid, caused by a pressure gradient or pressure differential across the membrane 3.4 dialysis fluid aqueous fluid containing electrolytes and, usually, buffer and glucose, which is intended to exchange solutes with blood during haemodialysis (3.13) or haemodiafiltration (3.11) NOTE 1 The
41、term “dialysis fluid” is used throughout this International Standard to mean the fluid (made from dialysis water and concentrates) which is delivered to the haemodialyser or haemodiafilter by the dialysis fluid delivery system. Such phrases as “dialysate”, “dialysis solution” or “dialysing fluid” ca
42、n be used in place of dialysis fluid. NOTE 2 The dialysis fluid entering the haemodialyser or haemodiafilter is referred to as “fresh dialysis fluid”, while the fluid leaving the haemodialyser or haemodiafilter is referred to as “spent dialysis fluid”. NOTE 3 Dialysis fluid does not include pre-pack
43、aged parenteral fluids used in some renal replacement therapies, such as haemodiafiltration and haemofiltration. 3.5 dialysis fluid compartment part of a haemodialyser (3.12) or haemodiafilter (3.10) through which dialysis fluid (3.4) is intended to pass 3.6 diffusion transport of solutes across a s
44、emipermeable membrane, caused by a concentration gradient 3.7 filtrate fluid removed from the blood across the semipermeable membrane into the dialysis fluid or filtrate compartment of a haemodialyser (3.12), haemodiafilter (3.10), haemofilter (3.14) or haemoconcentrator (3.9), due to a pressure gra
45、dient (including the contributions of both hydrostatic and oncotic pressures) across the semipermeable membrane 3.8 haemoconcentration process whereby plasma water and electrolytes are removed from diluted blood across a semipermeable membrane 6DIN EN ISO 8637:2014-03 EN ISO 8637:2014 (E) 3.9 haemoc
46、oncentrator device intended to perform haemoconcentration (3.8) 3.10 haemodiafilter device intended to perform haemodiafiltration (3.11) 3.11 haemodiafiltration process whereby solute imbalances in a patients blood are corrected by means of simultaneous convection and diffusion across a semipermeabl
47、e membrane, and by replacement with an appropriate physiological fluid NOTE Normally, the process also includes a net fluid removal. 3.12 haemodialyser device intended to perform haemodialysis (3.13) 3.13 haemodialysis process whereby solute imbalances in a patients blood are corrected, mainly by di
48、ffusion across a semipermeable membrane NOTE Normally, the process also includes a net fluid removal. 3.14 haemofilter device intended to perform haemofiltration (3.15) 3.15 haemofiltration process whereby solute imbalances in a patients blood are corrected, mainly by convection across a semipermeab
49、le membrane and replacement with an appropriate physiological fluid NOTE Normally, the process also includes a net fluid removal. 3.16 labelling written, printed, graphic or electronic matter that: is affixed to a medical device or any of its containers or wrappers or accompanies a medical device and which is related to identification, technical description and use of that medical device, but excluding shipping documents 3.17
