Problems solved by technology
Due to the yellow staining characteristics of iodophor, it is difficult to remove it with clean water at this time. Although it can solve the yellow staining with iodine-removing agent, the cost will increase, the operation will be more cumbersome, and the cleaning time will be prolonged, which reduces the operating room. Utilization
In addition, after this period of time, iodophor dripped on the floor, causing irreversible yellow pollution and damage, which greatly affected the doctor's vision, seriously affected the safety of the operation, and greatly reduced the life of the floor.

Abstract
The invention discloses traceless povidone iodine disinfectant which is prepared from, by weight, 4.0%-4.5% of polyvinylpyrrolidone, 0.45%-0.55% of iodine, 0.2%-0.8% of chelating agents, 0.2%-0.8% of stabilizer, 0.1%-0.2% of potassium hydroxide, 0.4%-0.8% of disodium hydrogen phosphate, 0.2%-0.8% of citric acid, 0.1%-0.5% of potassium iodide, 0.2%-0.5% of potassium iodate and the balance water. According to the traceless povidone iodine disinfectant, after iodide and polyvinylpyrrolidone are in complexation, a certain complexation and wrapping technology is adopted, the traceless povidone iodine disinfectant is cleaned from a floor with clean water within 24 hours, and nearly no yellow trace exists when observation is conducted with eyes. Compared with ordinary povidone iodine, namely iodophor, the traceless povidone iodine disinfectant has great advantages on the aspect of floor yellowing, so that the visual influence on operating personnel in an operating room is reduced, and the service life of the floor of the operating room is prolonged.
Description
technical field [0001] The invention relates to a povidone-iodine disinfectant, in particular to a traceless povidone-iodine disinfectant. Background technique [0002] With the development of the economy and the improvement of the medical level, people are increasingly pursuing the safety of the operating room. Povidone-iodine disinfectant is a necessary disinfection product in the operating room. [0003] Yellow staining is the phenomenon that it is difficult to remove with water after contacting with objects for a certain period of time during the use of iodophor. At present, what is known to the public is that povidone iodine can cause yellow stains on the skin and the ground during use. In the operating room, during the use of povidone-iodine (povidone iodine), it will inevitably be spilled on the floor. Since the operation process generally takes more than 6 hours, even the cleaning staff will clean the floor at this time. Due to the yellow staining characteristics o...
