Abstract
The present invention relates to technical field of medical instruments, disclose a kind of medical catheter hydrophilic coating, including the coating solution composition that there is the high molecular polymer of hydrophilic group or monomer and solids content is 5% 25%.Coating solution comprises the aqueous dispersion of the urethanes of a solids content 36% 46% and the polysiloxanes of a solids content 19% or silicone emulsion.It has good hydrophilicity, the most nontoxic, good with bonding catheter.
Description
Technical field
The present invention relates to technical field of medical instruments, particularly relate to a kind of medical catheter hydrophilic coating.
Background technology
Catheter, stomach tube are conventional plug-in type medical apparatus and instruments, owing to its needs are inserted in the patient, so to its table
The flexibility in face and comfortableness have higher requirement.And hydroaropic substance has preferable hydrophilic, have and well lubricate effect
Really, but hydroaropic substance is due to some material properties of itself, it is impossible to reach the requirement of medical apparatus and instruments articles for use, as to human body
Toxic effect etc..
Therefore, a kind of medical catheter hydrophilic coating of research, use the comfort level of conduit, eliminate hydrophilic painting improving patient
The toxic and side effects of layer, becomes skilled artisan's problem demanding prompt solution.
Summary of the invention
It is desirable to provide a kind of medical catheter hydrophilic coating, well solving the problems referred to above, it has well
Hydrophilicity, the most nontoxic, good with bonding catheter.
The technical scheme is that a kind of medical catheter hydrophilic coating, including the high molecular polymerization with hydrophilic group
Thing or monomer and the coating solution that solids content is 5%-25% form.
Further, described coating solution comprises the aqueous dispersion of urethanes of solids content 36%-46%
Polysiloxanes or silicone emulsion with a solids content 19%.
Further, described coating solution is possibly together with the cross-linking agent of urethanes.
Further, the high molecular polymer described in hydrophilic group contains SiO2 nanoparticle.
The invention has the beneficial effects as follows: the present invention will have the high molecular polymer of hydrophilic group or monomer and solids content
Coating solution for 5%-25% is crosslinked together, is formed and a kind of has good hydrophilicity, the most nontoxic and conduit
Bonding good hydrophilic coating, compared with existing single hydrophilic coating or lubricant, the hydrophilic ability of the present invention improves
More than 30%, when it is coated in catheter surface, lubricant effect is the best, and when patient inserts, comfortable cleaning, reaction is good.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below the present invention is carried out further
Describe in detail.
Embodiment one: the invention provides a kind of medical catheter hydrophilic coating, including the macromolecule with hydrophilic group
Polymer or monomer and the coating solution that solids content is 5% form.
Coating solution comprises the aqueous dispersion of the urethanes of a solids content 36% and a solids content 19%
Polysiloxanes or silicone emulsion.Coating solution is possibly together with the cross-linking agent of urethanes.There is the high score of hydrophilic group
Sub-polymer contains SiO2 nanoparticle.
The present invention will have the high molecular polymer of hydrophilic group or monomer and coating solution is crosslinked together, forms one
There is good hydrophilicity, the most nontoxic hydrophilic coating good with bonding catheter, it is demonstrated experimentally that above-mentioned hydrophilic coating
Hydrophilic ability improves more than 27.8%, and when it is coated in catheter surface, lubricant effect is the best, when patient inserts, comfortable
Cleaning, reaction is good.
Embodiment two: a kind of medical catheter hydrophilic coating, including high molecular polymer or the monomer with hydrophilic group
With the coating solution composition that solids content is 25%.
Coating solution comprises the aqueous dispersion of the urethanes of a solids content 46% and a solids content 19%
Polysiloxanes or silicone emulsion.Coating solution is possibly together with the cross-linking agent of urethanes.There is the high score of hydrophilic group
Sub-polymer contains SiO2 nanoparticle.
It is demonstrated experimentally that the hydrophilic ability of above-mentioned hydrophilic coating improves more than 30.1%, when it is coated in catheter surface, profit
Sliding effect is the best, and when patient inserts, comfortable cleaning, reaction is good.
The present invention will have the high molecular polymer of hydrophilic group or monomer and coating solution is crosslinked together, forms one
There is good hydrophilicity, the most nontoxic hydrophilic coating good with bonding catheter, it is demonstrated experimentally that single with existing
Hydrophilic coating or lubricant are compared, and the hydrophilic ability of the present invention improves more than 30%, when it is coated in catheter surface, and lubrication
Effect is the best, and when patient inserts, comfortable cleaning, reaction is good.
Certainly, the present invention also can have other various embodiments, in the case of without departing substantially from present invention spirit and essence thereof, ripe
Know those skilled in the art and can make various corresponding change and deformation according to the present invention, but these change and deformation accordingly
All should belong to the protection domain of appended claims of the invention.
