Description

Polishing maintenance oil for medical equipment and preparation method thereof

technical field

The invention relates to a glazing maintenance oil for medical instruments, or lubricating oil, which is used for the maintenance and lubrication of surgical instruments in hospitals.

Background technique

After being used for a period of time, the shaft joints and surfaces of hospital surgical instruments are not as flexible and smooth as they were when they were just put into use, and even rusted, which affects the normal performance and shortens the service life. In order to ensure normal use, maintenance should be carried out.

Contents of the invention

The purpose of the present invention is to provide a kind of glazing and maintenance oil for medical equipment, which has better compatibility with human tissue, is easily soluble in water, is easy to clean, can protect the performance of medical equipment, and has a good antirust effect, prolonging the The service life of the medical device; the invention also provides a scientific, reasonable, simple and easy preparation method.

The glazing and curing oil for medical devices of the present invention, its batching quality is composed of: polydimethylsiloxane [SF96 (350)] 10-30%, silicone oil [Viscasil (10000)] 10-30% , 5-20% oleic acid, 30-60% mineral oil [Isopar M], 2-10% ester wax [Hoechst Wax E] and 5-10% olefinic phenol polyoxyethylene ether [OPE-7].

Various component raw materials can be purchased directly.

The glazing and curing oil for medical devices of the present invention has a scientific and reasonable, simple and easy preparation method as follows:

It is prepared by stirring and mixing at a temperature of 60-90°C.

in:

The temperature is preferably the heating temperature of the water bath, preferably controlled at 70-80°C;

It is suitable to control the stirring speed at 500-800N/min, preferably 600N/min.

When mixing, it is best divided into three mixing processes. Use part of the mineral oil (which can dissolve the ester wax) to dissolve the ester wax to obtain an ester wax solution, and add polydimethylsiloxane to the remaining mineral oil. Alkanes, siloxane oil and oleic acid are mixed to obtain a mineral oil solution, and then the ester wax solution is added to the mineral oil solution and mixed evenly, and finally an alkene-based phenol polyoxyethylene ether is added.

The specific control after adding alkenyl phenol polyoxyethylene ether is as follows: keep the heating temperature of the water bath, and stir for 8 to 10 hours to react.

The glazing and curing oil for medical instruments of the present invention is used for the maintenance and lubrication of surgical instruments in hospitals. It is easily soluble in water, easy to clean, has good compatibility with human tissue, will not damage the gas permeability, mechanical properties and other properties of metal materials, has very low surface tension, high surface activity, and high hydrophobicity Good resistance to shear force, no corrosion to metals such as medical devices, and good antirust effect. It can be used for both automatic and manual operations. During automatic cleaning, the foam is low, which is not only conducive to the operation of equipment, but also convenient to save water. Maintenance of medical devices ensures the normal performance of medical devices, prolongs the service life of medical devices, and reduces the cost of using medical devices. The preparation method of the invention is scientific and reasonable, simple and easy to implement.
