Description

technical field [0001] The invention relates to a disinfectant, in particular to a disinfectant for cleaning and disinfecting a hemodialysis machine and a preparation method thereof. Background technique [0002] Hemodialysis machine cleaning fluid is an important reagent in the daily use and maintenance of the coagulation analyzer. It cleans the counting lines, colorimetric cells and jewel holes of the coagulation analyzer to stabilize the instrument and prolong the life of the instrument. The cleaning solution can dissolve blood clots and other dirt, and rinse with the diluent, so as to achieve the purpose of cleaning the counting pipeline system of the coagulation analyzer. The hemodialysis machine is a kind of medical equipment. For the safety of use, the machine needs to be cleaned and disinfected after each use. Infection is one of the common complications of long-term hemodialysis patients, and it is the second cause of death in dialysis patients with end-stage renal...
