[0002] Medical disinfectants are used in large quantities as medicines that are needed in hospitals on a daily basis. If all finished disinfectants are purchased, the cost will be high. At present, most hospitals usually use high-concentration disinfectants to dilute or mix the required disinfectants by themselves to reduce costs. However, although self-diluting and configuring disinfectants can reduce the cost of using disinfectants, due to the lack of relevant dilution equipment, manual mixing and dilution requires the use of relevant measuring cups and other utensils.

Moreover, since the measuring cups and stirring vessels used in manual configuration are open containers, it is difficult to avoid the entry of external dust and other debris during configuration, which affects the quality of the final disinfectant product.
