Lubricating and antirusting agent for medical appliance with hot-rinsing oil phase transfer performance

Abstract

The invention discloses a lubricating and antirusting agent for a medical appliance with hot-rinsing oil phase transfer performance and belongs to the technical field of fine chemical industry. An aqueous solution of the lubricating and antirusting agent is converted into a coarse dispersion system from a lyosol system in a certain temperature range. During the hot rinsing of the medical appliance, the coarse dispersion system formed by the lubricating and antirusting agent in a hot water solution is a hot rinsing solution, an oil phase ingredient in the coarse dispersion system can be divorced from an aqueous phase and transferred to the surface of the medical appliance to form a relatively-big-thickness and uniform-covering oil film and exert lubricating and antirusting actions, and theproblems that the medical appliance gets rusty and joints are obtuse due to the fact that an oil film of the lubricating and antirusting agent is too thin and is non-uniform in covering are solved.

Description

[0001] 1. Technical field [0002] The content of the present invention relates to a lubricating and antirust agent for medical equipment, in particular to a lubricating and antirusting agent for medical equipment with thermal rinsing oil phase transfer performance, which belongs to the technical field of fine chemicals. [0003] 2. Technical Background [0004] During the daily operation of the hospital, a large number of stainless steel or other metal medical instruments are used, such as scalpels, surgical scissors, hemostatic forceps, curved plates, tweezers, etc. These metal medical instruments will be oxidized and corroded during use, cleaning, disinfection, sterilization and storage, resulting in instrument rust and joint failure, which not only increases the risk of infection for patients, but also increases the operating cost of the hospital. In order to prolong the service life of metal medical devices and prevent the occurrence of infection, hospitals generally use l...

Problems solved by technology

[0005] At present, the lubricating and antirust agent for medical equipment is diluted with water in a certain proportion before use in hospitals. The components of the lubricating and antirust agent in the solution are in the form of molecules or colloids and other particles. The diameter of these particles is between 0.001-0.1μm, and the particle size is not only small And it is not affected by the water temperature. The thickness of the oil film formed on the surface of the device is thin and uneven, and the thickness of the oil film is less than 5 μm. Not only the lubrication effect on the medical device is poor, but also the oxygen in the air can easily penetrate the thin oil film to undergo oxidation reaction. And then corrode metal instruments, causing rust or blunt joints

[0006] At present, there are hydrogen bonds between micellar particles or molecules and water molecules in the aqueous solution of lubricating and antirust agents for medical devices used in hospitals, so that they are bound in solvent water, and the components of lubricating and antirust agents cannot be completely and effectively transferred during the hot rinsing process. To the surface of the device, most of it is discharged as waste liquid together with the aqueous solution, resulting in waste of resources

[0007] The hot rinse liquid of lubricating and antirust agent for medical instruments contacts the surface of medical instruments through the hot rinsing process of the medical cleaning machine. The adhesion of the current hot rinse liquid for lubricating and antirust agents is relatively weak. It falls off under the action of gravity, which reduces the effect of lubrication and antirust
