26、ound. 3.2 collection device Bag, bellows, bottle or other container constituting a part of a drainage system designed for collecting liquids and connected to the drainage catheter directly or via a connecting tube. 3.3 drainage system Drainage catheter and collection device(s) and, where applicable,
27、 other accessories such as suction source(s), connecting tube(s), connector(s) or trocar(s). NOTE. A drainage system may be supplied either in the ready-for-use state or in a state requiring the assembly of some components by the user. Drainage may be achieved either by gravity, by negative pressure
28、 generated by an external power source, by manipulation by the user, or by the pre-evacuation of the collection device. 3.4 connecting tube Tube designed for the assembly of components of a drainage system. 3.5 trocar Needle, pointed rod, sleeve or any combination thereof which assists in inserting
29、the drainage catheter into the body tissue or cavity. 3.6 suction source Self contained device capable of exerting a negative pressure on a drainage catheter or system. NOTE. The suction source may be the collection device. 4 Requirements 4.1 Kink stability NOTE. This subclause will be prepared when
30、 a test method has been developed. 4.2 Resistance to deformation The drainage system or any component thereof intended to operate under negative pressure shall not show deformation sufficient to impair the function of the device at the maximum negative pressure stated by the manufacturer. This shall
31、 be determined on the sterilized, ready-for-use product as described in annex A. 4.3 Force at break 4.3.1 Connections When tested according to annex F of EN 1618 : 1997 the minimum force at break for connections shall be as given in table 1.

This clause will be prepared when a test method has been developed. 4.5 Freedom from leakage When tested according to annex D of EN 1618 : 1997 neither the drainage
34、system nor any components thereof shall leak at the maximum negative pressure stated by the manufacturer. 4.6 Impact resistance The collection device shall not leak when tested in accordance with annex B. The suction source shall not show any loss of vacuum greater than 2 % when tested in accordance
35、 with annex B. 4.7 Biocompatibility The drainage catheter and any other component of the drainage system intended to channel fluid into the patient shall be evaluated for biocompatibility and shall be free from biological hazard. NOTE. Methods for evaluation for biocompatibility are given in EN 3099
36、3. 4.8 Sterility The device shall comply with EN 556. 4.9 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 Labelling In addition to the requirements of EN 980 and prEN 1041 the following product
37、-specific details shall be presented on the individual packaging: a) size of the drainage catheter (i.e. outside diameter expressed in millimetres and length expressed in millimetres or centimetres); b) radio-detectability if claimed; c) effective collection capacity of the collection device express
38、ed in millilitres; d) the vacuum stability of any pre-evacuated suction source, given as the date when at least 80 % of the initial negative pressure as stated on the label will remain. NOTE. This may be the use until date as defined in prEN 1041. e) the maximum negative pressure in Pascals (Pa) whi
39、ch the drainage system, or any component thereof supplied separately, can withstand. NOTE. If the suction source is supplied with the system, this figure is the maximum operating pressure of the suction source.Page 5 EN 1617 : 1997 BSI 1997 Annex A (normative) Test method for resistance to deformati
40、on of a drainage system or any components designed to form a part thereof A.1 Principle The drainage system or component(s) thereof, assembled in a ready-to-use state, are exposed to the negative pressure stated on the label. The test specimen is inspected while under the negative pressure for evide
41、nce of deformation. A.2 Apparatus A.2.1 Water bath, at (37 2) C for the drainage catheter. A.2.2 Water bath, at (23 2) C for other components. A.3 Procedure Perform the test on the ready-for-use, sterile product. Condition those parts of the drainage catheter that are intended for insertion into the
42、 body in an atmosphere of 100 % RH or water at a temperature of (37 2) C (A.2.1) for not less than 15 min. Condition other components at 40 % RH to 60 % RH and a temperature of (23 2) C for not less than 15 min and test immediately after conditioning. Submit the non-perforated section of the drainag
43、e catheter and/or the entire drainage system and/or the individual components thereof (if supplied separately) to the stated negative pressure of the system for 60 s. Maintain the pressure for at least 60 s. Examine the test specimen by normal or corrected-to-normal vision during the test for eviden
44、ce of deformation. Annex B (normative) Test method for impact resistance of collection device B.1 Principle The collection device is submitted to free fall onto a hard surface and is then examined for evidence of damage in the form of leakage or loss of vacuum. B.2 Apparatus B.2.1 A test surface, wh
45、ich is: flat, so that no more than two points on its surface differ in level by more than 2 mm; rigid, so that it will not be deformed by more than 0,1 mm when an area of 100 mm 2 is loaded statically with 10 kg anywhere on the surface; sufficiently large that the device under test falls entirely up
46、on its surface; has a mass of at least 10 times that of the heaviest device to be tested. B.2.2 Means for measuring vacuum, capable of showing a difference of 1 % of the maximum vacuum. B.3 Procedure B.3.1 Collection device Assemble the collection device as for clinical use. Fill the collection devi
47、ce with water to its collecting capacity. Perform a free fall at an ambient temperature of (23 2) C from a height of 700 mm onto a hard surface (B.2.1). Inspect for leakage by normal or corrected-to-normal vision. B.3.2 Suction source Assemble the suction source as for clinical use. Ensure the sucti
48、on source is at the maximum negative pressure and measure and record the pressure. Perform a free fall at an ambient temperature of (23 2) C from a height of 700 mm onto a hard surface (B.2.1). Measure and record the pressure not less than 60 s after impact. Annex C (informative) Bibliography EN 309
