Take peroxyacetic acid as an example, disinfection process:
1, with a good disinfectant, start the reverse osmosis machine, according to the requirements of the disinfectant will be inhaled into the reverse osmosis machine, in the reverse osmosis machine drainage port with a test paper to detect the disinfectant outflow can be. Stop the reverse osmosis machine.
2, the disinfectant solution through the 2-stage buffer tank into the room pipeline (some water treatment is to use other methods, such as disinfection pump device, etc.), when the end of the pipeline, the sampling port with a test paper detected peroxyacetic acid.
3, this is to turn on all the blood dialysis machine, do not need to enter any mode, boot. About 5 to 10 minutes, each machine self-test time is not the same, the basic boot 10 minutes disinfectant filled with blood dialysis machine behind the pipeline is certainly not a problem, of course, with the test paper to detect the drainage port of each piece of equipment peroxyacetic acid outflow is the best!
4, turn off the hemodialysis machine, close to the pipeline filling disinfectant. Soak with the reverse osmosis machine for 30 minutes!
5, normal start reverse osmosis machine to start flushing, including the pipeline part, this time do not turn on the hemodialysis machine, flushing 1 to 2 hours after the residual test paper to detect the reverse osmosis machine's drainage port, the end of the pipeline sampling port has no peroxyacetic acid residue. At this point, turn all the hemodialysis machines on and go into flush mode. (About 20 to 30 minutes)
6, the last can be sampling test several hemodialysis machine drainage port test whether there is peroxyacetic acid residue.
7, all off, disinfection is complete.
The method is referred to as linked disinfection method.
Disinfection cycle, it is recommended to disinfect once a month, not more than three months at the longest. Bacteria are like coral polyps, they will secrete substances in the water treatment pipe wall to build a house, 3 months to build a good (Sweden Nobel Laboratory conclusions), built a good house and then you use the disinfectant solution to disinfect the house is no way to remove, there are only 2 ways: with a brush or a new pipeline. And a built house protects against bacteria and viruses, and falling tiles are pyrogenic.
It is also very important that the disinfector must be very clear about how the disinfectant goes when disinfecting, what it has to go through, and in addition to the machine, there may be a spare outlet, which must be disinfected to, rinsed to, and detected, and never, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever! Because some hospitals are part-time engineers, afraid of leaving a part of the disinfectant did not rinse clean. We disinfected water treatment is each machine each outlet to measure the effective concentration and residual concentration.
