Abstract
The invention provides a preparation method of a lubricant used for a medical catheter. The lubricant used for the medical catheter comprises raw materials in weight proportion as follows: 45-60 parts of a component A, 20-30 parts of a component B, 5-10 parts of polyvinylpyrrolidone and 8-15 parts of acetone, wherein the component A is prepared from raw materials in weight proportion as follows: 20-30 parts of water-borne polyacrylic resin, 55-65 parts of deionized water, 8-10 parts of ethyl alcohol and 3-5 parts of urea; the component B comprises raw materials in weight proportion as follows: 15-20 parts of methylcellulose, 10-30 parts of ethyl alcohol and 50-80 parts of deionized water. The prepared lubricant is hydrophilic and transparent, and is attached to the surface of the medical catheter to form a solid transparent film with the thickness of 0.02-0.05mm. When the catheter is coated with a super-lubricant coating, neither pre-proessing of the surface of the catheter nor addition of a bottom layer on the surface of the catheter is needed, all that is needed is to coat the surface of the catheter when the medical catheter is produced, and accordingly, the lubricant is very convenient to use.
Description
Technical field
The present invention relates to a kind of lubricant, particularly a kind of medical catheter with lubricator, also relates to above-mentioned preparation method.
Background technology
The cleaning of current urethral catheterization treating dysfunction bladder, bladder training etc. are clinical common disease treatment means, and clinical conventional various sterilized catheter carries out intubate.Due to ordinary urethral catheter before use, generally apply one deck paraffin oil at catheter surface; This method application and extensively, but there is many problems, as needed field-applied saxol before (1) clinical manipulation, needing relevant supplementary material, being unfavorable for clinical manipulation; (2) paraffin oil is in catheter surface poor adhesive force, has lubricant effect during insertion, does not substantially have lubrication when extracting, and causes a lot of misery to patient; (3) paraffin oil is oily lubricant, and cleaning is also inconvenient.In addition, also have other kind hydrophilic lubricant in the market, some chance water is muddy, has irritant reaction to tissue adherence; Have apply with conduit time, complex process, in order to strengthen and catheter surface firmness, often need conduit pretreatment and adding the situations such as primer coating.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, and provide a kind of method simple, the medical catheter of high lubricating effect with lubricator.
Another technical problem to be solved by this invention there is provided the preparation method of above-mentioned lubricant.
Technical problem to be solved by this invention is realized by following technical scheme, the present invention be a kind of medical catheter with lubricator, be characterized in, it is made up of the raw material of following weight proportion:
Component A 45-60, B component 20-30, polyvinylpyrrolidone 5-10, acetone 8-15;
Described component A is made up of the raw material of following weight proportion: aqueous polyacrylamide acid resin 20-30, deionized water 55-65, ethanol 8-10, carbamide 3-5;
Described B component is made up of the raw material of following weight proportion: methylcellulose 15-20, ethanol 10-30, deionized water 50-80.
With lubricator, to medical catheter of the present invention it be made up of the raw material of following weight proportion: component A 52, B component 25, polyvinylpyrrolidone 8, acetone 12.
Medical catheter of the present invention with lubricator, be made up of the raw material of following weight proportion by described component A: aqueous polyacrylamide acid resin 25, deionized water 60, ethanol 9, carbamide 4;
Described B component is made up of the raw material of following weight proportion: methylcellulose 18, ethanol 20, deionized water 65.
The invention also discloses a kind of medical catheter as described in above scheme preparation method with lubricator, be characterized in, by weight taking component A, B component, polyvinylpyrrolidone and acetone respectively, mixing and stirring, then, after airtight standing 20-30 hour, product is obtained.
In medical catheter of the present invention preparation method with lubricator, the preparation method of described component A is, its step is as follows: by deionized water, ethanol and carbamide mix homogeneously, after join in agitator, slowly add aqueous polyacrylamide acid resin while stirring, at 50-70 DEG C of temperature stir until aqueous polyacrylamide acid resin all dissolves, after be cooled to room temperature, to obtain final product.
In medical catheter of the present invention preparation method with lubricator, the preparation method of described B component is that its step is as follows: methylcellulose and ethanol mix and blend are formed turbid solution, after add deionized water and carry out dilution stirring until solution is limpid, to obtain final product.
Aqueous polyacrylamide acid resin of the present invention is that any one commercially available in prior art is applicable to produce lubricant.Such as: Hua Jinsi company limited of the U.S.; Address: Chinese Shanghai Jing'an District China. Room 1503, No. 1, Lane 1135, Wuding County road, Jing'an District, Shanghai; Phone: 86-021-62329851, the Hua Jinsi Hd2535 of production.
Compared with prior art, the lubricant that the present invention obtains is hydrophilic lubricant, transparent shape, can form the solid transparent film of 2-5 silk in medical catheter surface attachment.Surface with this coating medical catheter before use, flood 5-10 second in water after, catheter surface still keeps transparence; But its surface is extremely lubricated, its coefficient of friction will be reduced to 80-100 doubly, greatly reduce the misery of patient, without allergy when this lubricant contacts with tissue, have good biocompatibility.During this superslide coating coating conduit, do not need catheter surface pretreatment, do not need to add bottom at catheter surface yet, only need in its surface-coated when producing medical catheter, therefore very easy to use.
Detailed description of the invention
Below further describe concrete technical scheme of the present invention, so that those skilled in the art understands the present invention further, and do not form the restriction to its right.
