Description
Technical field
The present invention relates to haemodialysis cleaning technology field, specially a kind of hemodialyzer line clear method.
Background technique
Haemodialysis (HD) is one of acute or chronic renal failure kidneys of patients Replacement Therapy.It is by by internal blood
Liquid is drained in vitro, through one by the dialyzer that is formed without several hollow fibres, blood electrolysis similar with concentration containing body
Matter solution (dialyzate) carries out mass exchange inside and outside hollow fibre one by one, through disperse, ultrafiltration, absorption and convective principles,
It removes intracorporal metabolic waste, maintain electrolyte and acid-base balance；Moisture excessive in vivo is removed simultaneously, and will be by purification
The whole process of blood recovery is known as haemodialysis.
The equipment of haemodialysis includes haemodialysis control unit, water process and dialyzer, collectively constitutes hemodialysis system, blood
Dialysis machine is most widely used a kind of therapeutic equipments in blood purification treatment, is that a more complicated electromechanical integration is set
It is standby, it is made of dialyzate supplying monitoring device and extracorporal circulatory system monitoring device；Water treatment system, tap water need to successively through filtering,
Except iron, softening, active carbon, reverse osmosis treatment, only reverse osmosis water can be as the thinned water of concentrate dialysate, and to tap water
A series of device for carrying out processing is water treatment system；Dialyzate is by dialysis concentrate and reverse osmosis water containing electrolyte and base
It is obtained after diluting in proportion, ultimately forms the solution close with electrolyte balance concentration, to maintain normal electrolyte level, simultaneously
Base is provided to body, to correct acid poisoning existing for patient by higher base concentration.Common dialyzate base is main
For bicarbonate, also contain a small amount of acetic acid.The unstable chemcial property of bicarbonate is easy in alkaline environment with calcium and magnesium ion
It precipitates, forms not capacitive calcium carbonate and magnesium carbonate；In dialyzer downstream flow path, there is also from patient's body fat,
Protein and organic substance；These precipitating and organic substance handle not in time will will cause pipeline narrow even blocking, serious shadow
Ring dialysis-effect；In addition dialyzer before and after use if not to pipeline carry out not in time processing can generate a large amount of germ contaminations,
The bacteremia and septicemia that can cause patient when serious jeopardize patient vitals' safety.
It before and after hemodialysis apparatus use, needs to carry out cleaning treatment and maintenance to pipeline, avoids causing dialysis pipeline
Pollution, influences using effect and patient health；But existing line clear method is relatively simple, but cleaning effect is bad, in addition
Existing cleaning method is that pipeline is disassembled to carry out cleaning-sterilizing mostly, is then installed again, not only inconvenient, and is pacified
During dress secondary pollution can be caused to pipeline.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the existing defects, provides a kind of hemodialyzer line clear side
Method can effectively solve the problems in background technique.
To achieve the above object, the invention provides the following technical scheme: a kind of hemodialyzer line clear method, including
Following steps:

S2. the preparation of ozone: gas source is sent into ozone generator by gas source pipe；Ozone generator is generated by quartz burner
Ultraviolet light be irradiated to the air in spiral gas storehouse, make its generate ozone；
S3. the preparation of atomized water: by ultrasonic ultrasonic delay line memory to the water containing thimerosals such as hydrogen peroxide from liquid feeding bottle into
Row atomization；
S4. the ozone prepared in atomized water obtained in step S3 and step S2 is mixed into and is disappeared containing ozone and hydrogen peroxide etc.
The water mist of noxious material；
S5. it is not necessarily to dismantle the pipeline of hemodialyzer, directly closes dialysis liquid pipeline, other pipelines is kept normally to be connected to, it will be upper
It states water mist and Medical Devices pipeline is sent by snorkel, and the tail gas containing ozone being discharged from pipeline is made to enter gas-liquid separator
It is separated, liquid enters liquid-collecting bottle by tapping valve, and gas is sent to air bag by pipeline and collects；
S6. by water mist obtained in step S4 by connecting with dialysis apparatus pipeline one end in step S5, and make to be discharged from pipeline
The tail gas containing ozone enter gas-liquid separator and separated, liquid enters liquid-collecting bottle by tapping valve, and gas passes through pipeline
It is sent to air bag collection；
S7. after sanitized, ozone generator and atomizer stop working, at this moment, in dialysis apparatus pipeline also remain water mist and
Ozone, booster pump, which works on, sucks air, and after the air of sucking is filtered, dry and clean air is by stopping
The ozone generator only to work enters atomizer, is then entered in dialysis apparatus pipeline by snorkel, and water mist and ozone are discharged；
S8. after water mist and ozone are discharged, by configured physiological saline and dialysis apparatus piping connection, physiological saline flows in pipeline
It is logical, the air in pipeline is discharged, dialysis liquid pipeline is then opened, after dialysis pipeline carries out a circulation, start formally into
Row haemodialysis；
S9. after the completion of haemodialysis, dialysis liquid pipeline is closed, physiological saline is continued to one circulation of circulation in pipeline, then
It is heated to 80 DEG C after adding reverse osmosis water to dilute using internal thimerosal to carry out pipeline repeated flushing 15 minutes, reuses and adds reverse osmosis water

Also remain water mist and ozone in pipeline, booster pump, which works on, sucks air, dry after the air of sucking is filtered
And clean air enters atomizer by the ozone generator to stop working, then enters dialysis apparatus pipeline by snorkel
It is interior, water mist and ozone are discharged；
S12. after water mist and ozone are discharged, by configured physiological saline and dialysis apparatus piping connection, physiological saline is in pipeline
Air in pipeline is discharged circulation；
S13. after channel interior cleaning, be diluted with water rear detergent line outer wall using external disinfection liquid, external disinfection liquid by

Acid 20~30%, surplus are deionized water.
4. a kind of hemodialyzer line clear method according to claim 1, which is characterized in that rushed in the step S9
The inside thimerosal and reverse osmosis water used when washing is mixed according to the ratio of 1:29, the inside thimerosal and reverse osmosis water that when immersion uses
It is mixed according to the ratio of 1:24.
5. a kind of hemodialyzer line clear method according to claim 1, which is characterized in that the external disinfection liquid
It is made of the ingredient mixing of following volume ratio: kefir milk element 0.5%, turpentine oil 0.6%, aloe powder 0.3%, chlorhexidine hydrochloride 25%, lemon
