Problems solved by technology

[0003] At present, although there are many cleaning agents for medical instruments on the market, there are many problems. Some of them are easy to cause environmental pollution due to excessive phosphorus content, and some cause certain corrosion to metal instruments, thereby shortening the service life of medical instruments.
Moreover, there is a problem of poor detergency for more stubborn stains on medical devices

Abstract

The invention discloses a maintenance cleaner for medical devices and a preparation method thereof. The prepared maintenance cleaner for the medical devices has good removal effect on blood stain, wherein euphorbia lunulata, cassia seed and garlic are in synergistic effect and cooperate with effects of a surfactant to improve the effect of blood stain extraction to the optimum, and the maintenancecleaner has good antibacterial effect; nano-titania promotes the release of effective ingredients of euphorbia lunulata, cassia seed and garlic, and can stimulate the activity, so as to improve the cleaning effect of the obtained cleaner; extracted residual drug slag is used and cooperates with the effects of cellulose acetate, chitosan and gelatin, microspheres with good adsorption effect are prepared, and the defouling effect of the cleaner is enhanced.

Description

technical field [0001] The invention belongs to the technical field of medical cleaning agents, in particular to a maintenance cleaning agent for medical equipment and a preparation method thereof. Background technique [0002] Residual blood and mucus on the surface of medical devices will form a protective film on the surface of microorganisms, which will hinder the direct contact between disinfection and sterilization factors and bacteria or spores, thus affecting the sterilization effect. Literature shows that thorough and effective cleaning of reusable medical devices is the It is an important condition to ensure the success of sterilization, so it is very important to clean the instruments before sterilization. [0003] At present, although there are many cleaning agents for medical instruments on the market, there are many problems. Some of them are easy to cause environmental pollution due to excessive phosphorus content, and some cause certain corrosion to metal ins...
