Abstract
The utility model discloses PVC ultra -smooth hydrophilicity catheter relates to a catheter that is used for supplying the short -term instant catheterization of medical institutions or family's personal accomplishment to use. Its purpose be for provide a simple structure, surface friction force little, insert light convenient, can alleviate the painful PVC ultra -smooth hydrophilicity catheter of patient. The utility model discloses PVC ultra -smooth hydrophilicity catheter includes the catheter body, is provided with at least one on the catheter body and draws the urine hole, is provided with close water -base coating on the outer wall of catheter body.
Description
Technical field
This utility model be related to it is a kind of for medical institutions or household person as the instant urethral catheterization of short-term medical apparatus and instruments, it is special
It is not to be related to a kind of catheter.
Background technology
Catheter is the product for urethral catheterization that urology department is used, and existing catheter lubricity is bad, and coefficient of friction is big,
Easily make patient produce the pain as burning during insertion urethra, or even mucosa can be damaged and cause inflammation, thus be badly in need of a kind of profit
The good catheter of slip.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of PVC superslides hydrophilic catheter, its simple structure, table
Face frictional force is little, it is easy and convenient to insert, can mitigate patient's pain.
This utility model PVC superslide hydrophilic catheters, including urethral catheterization tube body, are provided with least one on urethral catheterization tube body
It is individual to draw urine hole, it is provided with hydrophilic coating on the outer wall of the urethral catheterization tube body.
This utility model PVC superslide hydrophilic catheters, wherein the hydrophilic coating is Jing conjugate solutions being coupled
After process, again the dip-coating of Jing coating solutions formed.
This utility model PVC superslide hydrophilic catheters, wherein the conjugate solution is by the proportioning of quality：It is silane coupled
Agent 0.5%-5%, dehydrated alcohol 60%-80%, distilled water 20%-40%.
This utility model PVC superslide hydrophilic catheters, wherein the coating solution is by the proportioning of quality：Polyethylene pyrrole
Pyrrolidone 1%-10%, dehydrated alcohol 50%-70%, polyurethanes 30%-50%.
This utility model PVC superslide hydrophilic catheter differences from prior art are that this utility model includes urethral catheterization
Tube body, is provided with least one and draws urine hole, simple structure on urethral catheterization tube body；Outside urethral catheterization tube body in this utility model
Hydrophilic coating is provided with wall, hydrophilic coating is rapid swelling after being soaked in water, and hydrophilic gel is formed, with excellent lubrication
Property, skin-friction force is little, and friction during insertion between catheter and patient's body is little, inserts easy and convenient, can mitigate patient's pain
It is bitter.
Hydrophilic coating in this utility model PVC superslide hydrophilic catheters is the coupling processing through conjugate solution
Afterwards, formed through coating solution dip-coating again, wherein coating solution includes polyvinylpyrrolidone, itself carries hydrophilic group
Group, when contacting with waterborne liquid, the hydrophilic group of polyvinylpyrrolidone is combined rear rapid swelling with water, and formation is hydrophilic to coagulate
Glue, lubricity is more excellent, and polyvinylpyrrolidone can be organically attached to silane addition coupling agent the table of urethral catheterization tube body
Face, simultaneously containing hydrophilic group and lipophilic group, hydrophilic group can be in combination with polyvinylpyrrolidone, and lipophilic group also may be used for silane coupler
In combination with PVP, PVP is set preferably to be attached to catheter surface, it is achieved thereby that super profit
Slip energy.
Below in conjunction with the accompanying drawings the utility model is described in further detail.
Description of the drawings
Fig. 1 is the structural representation of this utility model PVC superslide hydrophilic catheters.
Specific embodiment
As shown in figure 1, this utility model PVC superslides hydrophilic catheter includes urethral catheterization tube body 1, on urethral catheterization tube body 1
It is provided with least one and draws urine hole 11, two are provided with this utility model and draw urine hole 11, arranges on the outer wall of urethral catheterization tube body 1
There is hydrophilic coating 12.
Hydrophilic coating 12 is Jing after conjugate solution carries out coupling processing, Jing coating solutions dip-coating shape again in this utility model
Into wherein conjugate solution is by the proportioning of quality：Silane coupler 0.5%-5%, dehydrated alcohol 60%-80%, distilled water
20%-40%；Coating solution by quality proportioning be polyvinylpyrrolidone 1%-10%, dehydrated alcohol 50%-70%, poly- ammonia
Carbamate 30%-50%.
Using polyvinylpyrrolidone as coating material in this utility model, itself carry hydrophilic group, when with aqueouss
When liquid is contacted, the hydrophilic group of polyvinylpyrrolidone is combined rear swelling rapidly, formation hydrophilic gel with water, will not fall off and
Lubricity is more excellent, additionally, polyvinylpyrrolidone can be organically attached to urethral catheterization tube body by silane coupler
Outer wall, it is achieved thereby that super greasy property.
This utility model PVC superslides hydrophilic catheter is soaked in water tens second time using front need, urethral catheterization tube body
Surface will form hydrophilic gel, extremely lubricate, then the insertion end of urethral catheterization tube body is inserted into patient's urethra, and frictional force reduces,
Mitigate the stimulation to patient, mitigate patient's pain, comfort level is improved, meanwhile, the indwelling catheter time of medical personnel, high efficacious prescriptions can be shortened
Just.
Embodiment described above is only that preferred implementation of the present utility model is described, not to this practicality
New scope is defined, and on the premise of without departing from this utility model design spirit, those of ordinary skill in the art are to this
Various modifications and improvement that the technical scheme of utility model is made, all should fall into the protection of this utility model claims determination
In the range of.
