Disinfecting liquid used for disinfecting and cleaning water channel of hemodialysis machine and preparation method thereof

Abstract

The invention discloses a disinfecting liquid used for disinfecting and cleaning a water channel of a hemodialysis machine and a preparation method thereof, relating to a disinfecting liquid and a preparation method thereof. The method solves the problems that the existing oxidized disinfectant and citric acid can not be used simultaneously, and the oxidized disinfectant can generate unpleasant smell after being decomposed. The disinfecting liquid used for disinfecting and cleaning the water channel of the hemodialysis machine is prepared by the citric acid, an acid adjusting agent, acid protease and hydrogen peroxide; the preparation method comprises the following steps of: dissolving the citric acid into high-purity water to prepare citric acid water solution, then adding the acid adjusting agent till the pH value of the citric acid water solution is 1.5 to 2.0, then adding the acid protease, standing for 1 to 2 hours, then adding the hydrogen peroxide and obtaining the disinfectingliquid used for disinfecting and cleaning the water channel of the hemodialysis machine. The disinfecting liquid can lead disinfecting and cleaning of the part of the water channel of the hemodialysis machine to be completed simultaneously, and the products after being decomposed by the hydrogen peroxide in the disinfecting liquid is colorless and tasteless water and oxygen which can not cause secondary damage to surrounding organisms.

Description

Technical field [0001] The invention relates to a disinfectant and a preparation method thereof. Background technique [0002] Disinfection and cleaning of the water circuit part of the active hemodialysis machine cannot be carried out at the same time. Oxidizing disinfectant is used to disinfect the water circuit part, and citric acid is used to clean the water circuit part, because the oxidation disinfectant and citric acid will undergo a disproportionation reaction to produce vitamin C derivatives. Crystals block the waterway of the hemodialysis machine, so the oxidizing disinfectant and citric acid cannot be mixed at the same time, which results in a long disinfection and cleaning time, increasing the operation time of medical staff and the maintenance cost of the hospital, and the existing disinfectants (sodium hypochlorite, Peroxyacetic acid, glacial acetic acid) are not easy to decompose during use. If there are residues, it will cause medical accidents. Disinfectants will...
