Description
Technical Field
The invention belongs to the technical field of medical washing, and particularly relates to a lubricant for transparent medical instruments and a preparation method thereof.
Background
Most of the lubricants for medical instruments are milky white, and obvious white spots can remain after cleaning and drying. The main reason is that the main component of the white lubricating oil is white oil, the white oil is emulsified by an emulsifier and compounded by other auxiliary materials to form water-soluble white lubricating oil, but white spots are separated out from the white lubricating oil after the white lubricating oil is dried. In addition, the use liquid is opaque, so that the instrument cannot be visualized during manual instrument treatment, and operation is inconvenient.
Although the water-soluble lubricating antirust agent disclosed in patent No. CN104531321A for surgical instruments and the preparation method thereof solve the problem of residual white spots, the lubricating effect of the propylene glycol and the methoxypolyethylene glycol applied to the water-soluble lubricating antirust agent for the surgical instruments is not good enough for the medical instruments.
Therefore, there is a need for a lubricant for medical devices, which can solve the problem of white spots after the lubricant is dried, has excellent lubricating performance, and most importantly, can be used for visualizing the devices during use.
Disclosure of Invention
The invention aims to provide a lubricant for transparent medical instruments, which is transparent and visible, completely water-soluble and excellent in lubricating performance, and a preparation method thereof aiming at the defects.
The technical scheme of the invention is as follows: a lubricant for transparent medical instruments, which consists of the following components: water-soluble base oil, additives, antirust bactericides and water; the lubricant is colorless and transparent, and is soluble in water and alcohol.
15-25 parts by weight of water-soluble base oil; 5-10 parts of an additive; 0.5-1 part of antirust bactericide.
The water-soluble base oil is DOW DOW product water-soluble polyether and does not contain paraffin and organic silicon. The base oil is colorless and transparent, has reliable safety and does not threaten the physical health of patients.
The additive is a low-foaming surfactant polypropylene glycol. The adopted polypropylene glycol has low foam surface activity, can increase the solubility of the water-soluble base oil in water, and can not remain after lubrication.
The antirust bactericide is food-grade sodium dehydroacetate. The antirust bactericide has a strong inhibition effect on bacteria and also has an antirust effect.
The preparation method of the lubricant for the transparent medical instrument comprises the following steps:
(1) preparing a premix A: firstly, adding water-soluble base oil into a reactor, and then adding an additive to dissolve completely to obtain a premix A;
(2) preparing a premix B: adding the antirust bactericide into water for dissolving to obtain a premix B;
(3) preparing a lubricant: and (3) mixing the premix A obtained in the step (1) with the premix B obtained in the step (2) to obtain the lubricant.
The invention has the beneficial effects that: the lubricant for the transparent medical instrument is a colorless transparent lubricant, and white spots cannot be remained on the surface of the instrument after cleaning; can have better compatibility with human tissues; and has good lubricating property. When the lubricant is used for soaking lubricating instruments, visualization is realized, the instrument state is easy to observe, and the operation is convenient.
Drawings
FIG. 1 is a comparison of the lubricant for transparent medical devices of the present invention with a currently available lubricant; wherein, the first left is purified water, the second left is the transparent lubricant stock solution of the invention, and the first right is the ordinary milky lubricant stock solution.
FIG. 2 is a diagram illustrating a comparison between the lubricant for transparent medical devices according to the present invention and a lubricant currently available on the market; wherein the left figure is the using state of the milky white lubricant, and the right figure is the using state of the transparent lubricant.
Detailed Description
The present invention will be described in detail below with reference to examples.
Example 1
The lubricant for the transparent medical instrument comprises the following components in parts by weight: 20 parts of DOW DOW product water-soluble polyether, 10 parts of low-foam surfactant polypropylene glycol, 0.5 part of food grade sodium dehydroacetate and the balance of water; the lubricant is colorless and transparent, and is soluble in water and alcohol.
The preparation method of the lubricant for the transparent medical instrument comprises the following steps:
(1) preparing a premix A: firstly, adding water-soluble base oil into a reactor, and then adding an additive to dissolve completely to obtain a premix A;
(2) preparing a premix B: adding the antirust bactericide into water for dissolving to obtain a premix B;
(3) preparing a lubricant: and (3) mixing the premix A obtained in the step (1) with the premix B obtained in the step (2) to obtain the lubricant.
As is apparent from FIG. 1, the lubricant for transparent medical devices according to the present invention has transparency comparable to that of purified water.
As can be seen from FIG. 2, the lubricant is diluted in a simulated hand washing mode, and the lubrication process of the medical device can be clearly seen during the use of the lubricant.
Example 2
The lubricant for the transparent medical instrument comprises the following components in parts by weight: 18 parts of DOW DOW product water-soluble polyether, 10 parts of low-foam surfactant polypropylene glycol, 0.5 part of food grade sodium dehydroacetate and the balance of water; the lubricant is colorless and transparent, and is soluble in water and alcohol.
The preparation method is the same as example 1.
Example 3
The lubricant for the transparent medical instrument comprises the following components in parts by weight: 18 parts of DOW DOW product water-soluble polyether, 10 parts of low-foam surfactant polypropylene glycol, 1 part of food grade sodium dehydroacetate and the balance of water; the lubricant is colorless and transparent, and is soluble in water and alcohol.
The preparation method is the same as example 1.
The performance of the lubricants described in examples 1-3 was measured as follows. The method comprises the measurement of lubricating property, whether white spots remain, corrosivity and bacteriostasis.
1.
