31、 3 Definitions For the purposes of this European standard, the following definitions apply. 3.1 urethral catheter Tubular device intended for being introduced into the vesical cavity through the urethra in order to provide drainage and/or flushing of the bladder. 3.2 balloon capacity Volume of liqui

32、d to be introduced into the catheter in order to fill the inflation channel and inflate the balloon. 3.3 shaft Portion of the catheter excluding the tip, balloon(s), funnel(s) and/or sideport. 3.4 outside diameter Maximum dimension measured across the cylindrical portion of the shaft. 4 Requirements

33、 4.1 General All tests shall be carried out on the product in the ready-for-use state. 4.2 Surface finish When the catheter is ready for use (e.g. treated according to the manufacturers instructions) and is examined by normal or corrected-to-normal vision at 2,5 times magnification, the surface of t

34、he shaft, tip, balloon and eyes shall appear free from extraneous matter. 4.3 Dimensions 4.3.1 Size designation The size of the catheter shall be designated by its nominal outside diameter expressed in mm to the nearest 0,1 mm. Tolerances on this stated size shall be 0,33 mm. The balloon capacity sh

35、all be expressed in ml. NOTE. Additional units can also be given. 4.3.2 Lengths The minimum overall length (L) and shaft lengths (S) shall be as given in table 1 (see also figure 1).Page 4 EN 1616 : 1997 BSI 08-1999 1.

40、.6 Balloon security 4.6.1 When tested in accordance with the method given in annex C, the balloon shall not leak and shall not occlude the drainage eyes. NOTE. The change in profile at each end of the uninflated balloon should be smoothly blended with the shaft. The balloon should be capable of appr

41、oximately symmetrical expansion when filled with water at ambient temperature to its specified balloon capacity. 4.6.2 When tested by the method given in annex D, the percentage of water recovered shall be not lower than the value given in table D.2. 4.7 Kinkability NOTE.

Methods for evaluation for biocompatibility are given in EN 30993. 4.10 Sterility The device shall comply with EN 556. 4.11 Corrosion test When tested in accordance with the method given in annex A of EN 1618 : 1997, the test specimen shall not show any evidence of corrosion. 5 Symbols and

44、 labelling The symbols and information provided with catheters shall be as specified in EN 980 and prEN 1041, and in addition the following information shall be given: a) the manufacturers stated minimum and maximum balloon inflation volumes; b) the designated size as given in 4.3.1.Page 6 EN 1616 :

45、 1997 BSI 08-1999 | Annex A (normative) Test method for determining the strength of the catheter A.1 Principle Catheters fitted with balloons may be in situ for prolonged periods. Such catheters are therefore immersed for 14 days in simulated urine prior to testing. This step is omitted for catheter

46、s without balloons. A tensile force is applied to the union of the tip and shaft of the catheter. For catheters with lateral eyes, the tensile force is to be applied to the eyes. For catheters with no lateral eyes, the tensile force is applied between the shaft of the catheter and the drainage funne

47、l. On removal of this force, the catheter is examined for signs of failure. A.2 Reagents A.2.1 Simulated urine, pH approximately 6,6, of the following composition, the reagents being of recognized analytical grade: Urea 25,0 g Sodium chloride 9,0 g Disodium hydrogen orthophosphate, anhydrous 2,5 g A

48、mmonium chloride 3,0 g Potassium dihydrogen orthophosphate 2,5 g Creatinine 2,0 g Sodium sulfite, hydrated 3,0 g Distilled water to 1,0 l WARNING. This solution can support microbial growth. There is a strong possibility that large numbers of microorganisms will be present in the solution at the end

49、 of the tests described in A.3 and C.3. These procedures should be carried out by trained personnel taking appropriate precautions in the handling of the immersed catheter and the disposal of the contaminated solution. A.3 Apparatus A.3.1 Device for suspending catheter with lateral eyes, comprising a pin which passes through a drainage eye of the catheter, the pin having a diameter of between 50 % and 75 % of that of the drainage lumen of the catheter to be tested. An example of a suitable device is shown in figure A.1a). For cat
