Abstract

The invention relates to a medical equipment cleaning agent, which is prepared from the following components by mass percent: 1-10% of a dispersed scale inhibitor, 5-30% of a surface active agent, 5-15% of polymerase, 2-15% of a solvent, 1-10% of a bactericide, 1-10% of an anti-rust agent and the balance of water. A preparation method of the dispersed scale inhibitor comprises the steps of enabling allyloxy polyethylene glycol and glycidol, which are taken as raw materials, to be subjected to an anionic ring-opening reaction so as to synthesize a dendritic polyether monomer; enabling the obtained dendritic polyether monomer and acrylic acid to be subjected to a free radical polymerization reaction in a water phase to obtain the dispersed scale inhibitor. The medical equipment cleaning agent provided by the invention is simple and convenient to prepare, safe and non-toxic, thus being suitable for cleaning medical equipment.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a cleaning agent for medical equipment, a method for preparing a dispersed scale inhibitor and a method for preparing the cleaning agent. Background technique [0002] After surgical instruments are used, organic pollutants such as blood stains and oily tissue fluids often remain on the surface. Moreover, the repeated use of surgical instruments will lead to the accumulation of biofilm. It is worth mentioning that it is difficult to completely remove the biofilm by general cleaning methods. Biofilm is very harmful. According to experts' estimation, 65% of human bacterial infections are related to biofilm. After the biofilm is formed, 2400 times the amount of antibiotics is needed, and the lethal rate is as high as 5% to 60%. It is far from enough to simply rely on disinfection / sterilization to kill the bacteria in the biofilm. Only by completely removing the biofilm can the risk of infection...
