Specifically, washing the test sterilization method automatically according to dialyser of the present invention comprises and as shown in Figure 1 mastery routine makes whole device initialization in step 101.Enter step 102 energized, dialyser cleans the test decontaminating apparatus automatically and enters duty with the dialyser that is cleaned.Step 103 shows main menu D, and this menu has been listed flushing dialyser subprogram 104, flushing multiplexer subprogram 107, test dialyser subprogram 110 and 113 4 subprograms of test reuse device subprogram.User can start corresponding subprogram as required.For example, select flushing dialyser subprogram 104, judge whether to enter this subprogram,, then enter flushing dialyser program 106 if judged result determines to enter this subprogram by step 105; If be confirmed to be wrong, then return step 105 and reenter.
With reference to Fig. 2, select flushing dialyser subprogram 106 when user, enter step 201, KUF is 0 at this step initial setting dialyser ultrafiltrate coefficient, the capacity VOL of dialyser is 70, and judgement symbol RETURN=0 is shown.At step 202 couple dialyser ultrafiltrate coefficient KUF with capacity VOL judges or determine, go forward side by side then into selection KUF and VOL subprogram 301 (Fig. 3).
As shown in Figure 3, according to selecting dialyser ultrafiltrate coefficient KUF and capacity VOL flow process, at first determine dialyser ultrafiltrate coefficient KUF, step 302 below is to determine respectively to come the dialyser towards Xian with which type of flushing, test and sterilization classification by dissimilar dialysers to 304.Term " flushing " speech that the present invention uses comprises flushing, test and three aspects of sterilizing except that specific qualification.Wherein whether step 302 judges the KUF value less than 9, if less than 9, illustrates that it is small-sized being tested the disinfectant dialyser towards Xian, can promptly carry out the OO flushing by general rinsing requirement towards Xian.If the KUF value is greater than 9, this need judge than 9 big what, judge that in step 303 the KUF value is whether greater than 9 but in less than 15 scope, if in this scope, illustrate that the dialyser that is rinsed belongs to medium-sized, should promptly carry out CH towards Xian by medium rinsing requirement flushing; If judge KUF value greater than 15 in step 303, at this moment need to judge whether really if greater than 15, to illustrate that the dialyser that is rinsed is large-scale greater than 15 in step 304, need wash by force, promptly carry out HF and wash.If in step 304 judged result and be not more than 15, in case this situation occurs, program enters step 309 through step 305 (RETURN=1) and finishes, and returns step 203.
End enters and determines dialyser capacity VOL behind the determining of dialyser ultrafiltrate coefficient KUF.As previously mentioned, the initial value of capacity VOL setting is 70ml.Whether the actual capacity that enters the at first definite dialyser of step 306 is 70ml, if determine it is 70ml, then program enters step 309 end, and returns to step 203.If judge it is not 70ml in step 306, then judge whether it is greater than 70ml in step 307, if greater than 70ml, then enter step 309 and finish, and return step 203.If the result that step 307 is judged is not greater than 70ml, then enter step 308 and whether judge capacity VOL less than 70ml, if less than 70ml, program enters step 309 and finishes, and returns step 203.If not less than 70ml, then finish in step 309, and return to step 203 through step 305 (RETURN=1).
From the above mentioned, step 309 comprises fixed dialyser ultrafiltrate coefficient KUF and capacity VOL scope and fails determines above-mentioned data two states, and the step of returning then among Fig. 2 203 is carried out further judgment processing.
Turn back to Fig. 2 now, whether need make program in step 203 can continue, promptly make RETURN and equal 0 or equal 1 logical judgment, wherein equaling 0 condition is to have definite dialyser ultrafiltrate coefficient KUF value and dialyser capacity VOL value, shows to enter dialyser flushing state.If fail to determine KUF value and VOL value, or exist both one of can not determine that read-me can not continue, should turn back to the step 103 that Fig. 1 shows main menu D.
If selected dialyser ultrafiltrate coefficient KUF value and dialyser capacity VOL value are virtual values, read-me can enter the flushing state, be RETURN=0, at this moment flow process enters step 204 by step 203, determines whether undertaken by general cleaning procedure towards Xian Chengxu in this step.If be confirmed to be general flushing in step 204, promptly general cleaning procedure (OO cleaning procedure) is carried out in step 205 in KUF＜9.If in the step 204 general flushing that really admits a fault, then enter step 206 and confirm whether be medium cleaning,, enter medium cleaning procedure (CH cleaning procedure) in step 207 as confirming i.e. 9＜KUF＞15.As confirming in step 206, then enter step 208 and whether determine KUF greater than 15, if greater than 15, carry out by force towards Xian Chengxu (HF cleaning procedure); As not being greater than 15, illustrate that aforementioned program is wrong, return main menu D, i.e. the step 103 of Fig. 1.
To describe with regard to different classes of cleaning procedure respectively below.
Referring to Fig. 4, general cleaning procedure is described, promptly OO is towards Xian Chengxu.As shown in the figure, program starts from step 401, carries out the flushing first time in step 402, and in this step water flushing, the time is 1 minute.Finishing the first time behind Xian, enter step 403, is the preparation cleanout fluid in this step, and clear Xian's liquid can use hydrogen peroxide, hypochlorous acid, and preferably the commodity of U.S. HDC medical treatment company limited production are called the cleanout fluid of Lun Naling.With the Lun Naling cleanout fluid is example, and the concentration of the cleanout fluid of preparation is 2.5%, and consumption is 612ml.Treat that the preparation of Xian's liquid is finished clearly, program enters step 404, carries out the flushing second time, and flushing for the second time comprises that four-stage, phase I are to wash outside the film of dialyser with cleanout fluid, and Lun Naling is an example as previously described, and consumption is approximately 300ml, and the time is not limit.Second stage is to wash in the export-oriented film of the film of dialyser with cleanout fluid, uses Lun Naling equally, is approximately 20ml, and the time is approximately 100 seconds.Phase III is to clean in the film of dialyser with cleanout fluid, is approximately 280ml with Lun Naling, and the time is not limit.The quadravalence section be clean dialyser with clear Xian's liquid film outward in film, use Lun Nalingyue 10ml, scavenging period is approximately 65 seconds.Clean for the third time in step 405 then, this time is the water flushing towards Xian, and the time is approximately 40 seconds.
As previously mentioned, flushing of the present invention comprises towards Xian, test and three aspects of sterilizing, and therefore, finishes OO after the flushing of Xian Chengxu, needs the dialyser that is rinsed is tested.The purpose of test is whether the pressure whether doughnut of definite dialyser has damage and dialyser can bear can reach predetermined requirement, to determine that can this dialyser continue to use.Carry out first test in step 406, test contents is the actual capacity of dialyser, the result of test brings step 407 into, compare with predetermined value, if result relatively is that actual capacity is greater than setting value (RL=0), the capacity after the dialyser flushing that illustrates surpasses setting value, enters step 409 and carries out second test.If the result who judges in step 407 is not that the actual capacity of dialyser is not greater than predetermined value, illustrate that the hollow-fibre membrane of dialyser damages (RL=1), program enters step 408, and then returns to main menu D, the i.e. step 103 of Fig. 1.By after the dialyser actual capacity test, carry out stress test in step 409 to dialyser, the purpose of stress test is to determine whether dialyser exists rupture of membranes.The test result of step 409 is sent into step 410, compares with predetermined value, if judge pressure qualified (RL=1), program enters step 411, shows the actual capacity of the dialyser that actual measurement obtains and the pressure that can bear in this step, and preserves this data.Descend if the comparative result of step 410 is a pressure, illustrate that there has been rupture of membranes (RL=0) in dialyser, program enters step 408, and then returns to main menu D (Fig. 1).
After finishing test, OO enters sterilisation stage towards Xian Chengxu.At first begin to carry out sterilisation stage in step 412, at step 413 configuration disinfectant solution, disinfectant solution commonly used, as peracetic acid, formalin, the present invention is the disinfectant solution of the commodity Lun Naling by name that produces of U.S. HDC medical treatment company limited preferably, and this disinfectant solution and aforesaid Lun Naling cleanout fluid are identical product, when as disinfectant solution, its concentration is 3.5%, and configuration amount is 612ml.The configuration back is standby.15 seconds outside the first water flushing membrane of step 414 inner membrance, then step 415 respectively to film in and each 300ml of film outer filling disinfectant solution.Program enters step 416 and finishes, and returns to main menu D (step 103 of Fig. 1).
