Embodiment 1

[0020] The vegetable oil-based medical device lubricating oil of this embodiment includes castor oil polyoxyethylene (20) ether, hydroxypropyl methylcellulose, lauryl alcohol, polyethylene pyrrolidone, deionized water, and rapeseed oil;

[0021] The preparation method of the vegetable oil-based medical device lubricating oil of the present embodiment is as follows:

[0022] 1) Emulsify 26g of castor oil polyoxyethylene (20) ether, 5g of hydroxypropyl methylcellulose, 4g of dodecanol, 6g of polyvinylpyrrolidone and 145g of deionized water at 45°C to form an emulsion;

[0023] 2) Slowly add 14g of rapeseed oil into the emulsified liquid under the stirring condition of the emulsifier, then adjust the speed of the emulsifier to slowly increase it to 3000rpm, and stir and emulsify for 20min to form a vegetable oil-based lubricating oil for medical equipment.

Embodiment 2

[0025] The vegetable oil-based lubricating oil for medical equipment in this embodiment includes castor oil polyoxyethylene (80) ether, carboxymethyl cellulose, n-octanol, polyvinylpyrrolidone, Deionized water and canola oil;

[0026] The preparation method of the vegetable oil-based medical device lubricating oil of the present embodiment is as follows:

[0027] 1) Emulsify 29g castor oil polyoxyethylene (80) ether, 4g carboxymethyl cellulose, 6g n-octanol, 5g polyvinylpyrrolidone and 137g deionized water at 45°C to form an emulsion;

[0028] 2) Slowly add 12g of rapeseed oil into the emulsified liquid under the stirring condition of the emulsifier, then adjust the speed of the emulsifier to slowly increase it to 3000rpm, and stir and emulsify for 20min to form a vegetable oil-based lubricating oil for medical equipment.

Embodiment 3

[0030] The vegetable oil-based lubricating oil for medical equipment of this embodiment includes castor oil polyoxyethylene (40) ether, hydroxyethyl methylcellulose, cetyl alcohol, polyethylene glycol in a mass ratio of 34:6:5:5.5:130:15 pyrrolidone, deionized water, and rapeseed oil;

[0031] The preparation method of the vegetable oil-based medical device lubricating oil of the present embodiment is as follows:

[0032] 1) Emulsify 34g castor oil polyoxyethylene (40) ether, 6g hydroxyethyl methylcellulose, 5g cetyl alcohol, 5.5g polyvinylpyrrolidone and 130g deionized water at 45°C to form an emulsion;

[0033] 2) Slowly add 15g of rapeseed oil into the emulsified liquid under the stirring condition of the emulsifier, then adjust the speed of the emulsifier to slowly increase it to 3000rpm, and stir and emulsify for 20min to form a vegetable oil-based lubricating oil for medical equipment.

Abstract

The invention relates to a plant oil base medical instrument lubricating oil and a preparation method thereof. According to the mass ratio of (26-34) : (4-6) : (3-7) : (4-6) : (130-150) : (12-16), the lubricating oil comprises castor oil polyoxyethylene ether, a cellulose surface active agent, highalcohol, polyvinylpyrrolidone, deionized water and colza oil. The method comprises the following steps: firstly, uniformly emulsifying the castor oil polyoxyethylene ether, the cellulose kind of surface active agent, the highalcohol, the polyvinylpyrrolidone and the deionized water at the temperature of 45 DEG C, and forming emulsified liquid; secondly, adding colza oil into the emulsified liquid under the condition of stirring, then increasing the rotating speed, stirring and emulsifying for 20 min, and forming the plant oil base medical instrument lubricating oil. The vegetable oil and the surface active agent are adopted to prepare the water-soluble emulsified plant oil base medical instrument lubricating oil, a protecting film can be formed on the surface of the instrument, bubbles are less, the environment can be protected, and the lubricating oil has no influence on the sterilization effect.

Description

technical field [0001] The invention relates to a device lubricating oil and a preparation method thereof, in particular to a vegetable oil-based medical device lubricating oil and a preparation method thereof. Background technique [0002] The disinfection supply room is the supply department of the hospital's sterile equipment and is an important part of the hospital's work. At present, the main lubricants used for rust prevention or lubrication of medical devices are liquid paraffin or vaseline, but these two lubricants are insoluble in water, which will block the water vapor of high temperature and high pressure sterilization and reduce the sterilization effect. At the same time, instruments are prone to rust after sterilization. And the operation needs to be painted by hand to complete, and the quality is difficult to control. [0003] In order to improve the quality of medical equipment after cleaning and prolong the service life of medical equipment, the development...
