Description
Technical field
The utility model relates to a kind of haemodialysis water dispenser decontamination systems, belong to medical disinfection technology field.
Background technique
For dialysis patient, contact of the water with blood is realized simply by a kind of semi-permeable membrane, within certain limits,
Semi-permeable membrane is not selected by its substance.Hemodialysis patients are exposed to a large amount of dialyzate (monthly at least more than 1000 liters)
In the middle, therefore, water for dialysis has strict requirements, it is necessary to meet " YY0572-2015 " water for dialysis standard.Wherein bacterium colony is total
Number < 100cfu/ml, endotoxin < 0.1EU/ml.To guarantee that microorganism is in a safe range in water, it is necessary to water for dialysis
Processing equipment regular disinfection.
And commonly using sterilization method at present has chemical disinfection and heat sterilization.Chemical disinfection usually≤3 months sterilize 1 time, select
Oxidative disinfectant needs a large amount of pure water rinsings after disinfection, waste and have residual.Heat sterilization usually sterilizes 1~7 time weekly, selects
85~90 DEG C of high temperature pure water carry out disinfection to system, and disinfection cycle is short, noresidue, but require height to pipeline, and leakproofness will be got well；
It cannot carry out disinfection to reverse osmosis membrane, many costs will increase using high temperature membrane.
Utility model content
The purpose of the utility model is to provide a kind of haemodialysis water dispenser decontamination systems, and design is scientific and reasonable, structure letter
It is single, it is easy to operate, efficient, noresidue is sterilized, it is safe to the human body harmless.
Haemodialysis water dispenser decontamination system described in the utility model, including balancer, first-stage reverse osmosis device and second level
Reverse osmosis unit, balancer are connected with pretreated water device, and balancer is also connected with subacidity Water generator and primary pump respectively,
It primary pump and first-stage reverse osmosis device, two stage pump, second level reverse osmosis apparatus and is sequentially connected with water spot；With water spot and second level reverse osmosis
Pipeline between saturating device is connected with balancer；Subacidity Water generator, primary pump and two stage pump are connected with control system.
The balancer is connected with drain valve.
The pipeline being connected with water spot with balancer is equipped with constant pressure valve, ensure that the pressure with water spot.
The second level reverse osmosis apparatus and between water spot be equipped with safety valve, improve safety coefficient.
The balancer is connected with liquid level sensor, and liquid level sensor is connected with control system.
The utility model is formed by circulation waterway before with water spot, ensure that entire decontamination system is in running water circulation
State, so that disinfection is thorough.
The course of work of the haemodialysis water dispenser decontamination system is as follows:
When not sterilizing, pretreated water enters balancer, successively passes through at first-stage reverse osmosis processing and two-pass reverse osmosis
Reason, finally reaches with water spot, and extra water flows back into balancer.
When disinfection, first start subacidity Water generator, generates subacidity electrolysis water, liquid is controlled by liquid level sensor
Position, until the liquid level of setting stops water processed.Then it is in close state drain valve, starts primary pump and two stage pump, starts to follow
Ring disinfection after running a period of time, opens drain valve, the subacidity electrolysis water in balancer is exhausted.Drain valve is then turned off,
So that pretreated water flows into balancer, after the liquid level for reaching setting, starts primary pump and two stage pump is rinsed pipeline, rush
After washing a period of time, flushing water is exhausted, completes disinfection.
Compared with prior art, the utility model has the following beneficial effects:
Design is scientific and reasonable for the utility model, and structure is simple, easy to operate, high to the Disinfection Effect of hemodialysis water dispenser and pipeline
Effect, noresidue, it is safe to the human body harmless.
