Abstract
The invention discloses a urethral catheter manufacturing method, which comprises the following steps: firstly respectively manufacturing a urethral catheter body with a urine conducting outlet, an inner urethral catheter with an air bag water injection channel, and a charging branch tube with an external observing air bag; b. washing and airing the urethral catheter body, the inner urethral catheter and the charging branch tube through absolute ethyl alcohol, soaking the urethral catheter body, the inner urethral catheter and the charging branch tube into a coupling solution, taking out and drying in a drying oven after soaking for a while, wherein the coupling solution is prepared by stirring and mixing the following ingredients in parts by weight: 1 part of silane coupling agent, 12 parts of absolute ethyl alcohol and 4 parts of distilled water; and c. then assembling the urethral catheter body, the inner urethral catheter and the charging branch tube, and processing the urine conducting outlet in the upper end of the urethral catheter and internal connecting threads on the lower end of the urethral catheter. The manufactured urethral catheter is adopted to achieve better lubrication performance.
Description
Technical field
The present invention relates to cut field, specifically, be a kind of catheter manufacture method.
Background technology
It is known that, urethral catheterization is one of the most common medical care precess, catheter is usually used in helping patient collect urine or help the home-bound patient such as postoperative to urinate, being also applied for the urine retention caused because of lower urinary tract obstruction, urethral catheterization operation is also applied to rescue the situations such as critical patient, general anesthesia Preoperative Method, intravesical drug perfusion or bladder irrigation.Existing production technology and detection method determine the case that latex catheter will necessarily occur that in Clinical practice balloon occlusion, sacculus rupture, tract seepage and urethra allergy infect, and can increase the ratio these cases occur because of the reduction of production management level.
Summary of the invention
It is desirable to provide a kind of catheter manufacture method, to solve the problems referred to above.
For achieving the above object, technical scheme is as follows:
A kind of catheter manufacture method, it is characterised in that comprise the following steps:
Processing has the catheter body of catheterizing port, the urethral catheterization inner tube with air bag waterflood path, the inflation arm with external observation air bag the most respectively；
B. by catheter body, urethral catheterization inner tube, inflate Zhi Guanyong washes of absolute alcohol and dry, again catheter body, urethral catheterization inner tube, inflation arm are dipped in conjugate solution, wherein conjugate solution presses silane coupler 1 part, dehydrated alcohol 12 parts, 4 parts of stirrings of distilled water mix, and are taken out to oven for drying after soaking a period of time；
The most then by catheter body, urethral catheterization inner tube, inflation arm assemble, and process catheterizing port in catheter body upper end, lower end processes connection female thread.
Further, by inserting in extrusion die by melted PVC material in described a step, utilize screw extruder melted PVC material to be extruded from extrusion die, form catheter body.
The beneficial effects of the present invention is: the catheter of the present invention utilizes PVC to make, and after the coupling processing of conjugate solution, lubricity is more excellent.
Detailed description of the invention
The present invention will be further described for embodiment in detail below.
A kind of catheter manufacture method, comprises the following steps:
Processing has the catheter body of catheterizing port, the urethral catheterization inner tube with air bag waterflood path, the inflation arm with external observation air bag the most respectively；
B. by catheter body, urethral catheterization inner tube, inflate Zhi Guanyong washes of absolute alcohol and dry, again catheter body, urethral catheterization inner tube, inflation arm are dipped in conjugate solution, wherein conjugate solution presses silane coupler 1 part, dehydrated alcohol 12 parts, 4 parts of stirrings of distilled water mix, and are taken out to oven for drying after soaking a period of time；
The most then by catheter body, urethral catheterization inner tube, inflation arm assemble, and process catheterizing port in catheter body upper end, lower end processes connection female thread.
By inserting in extrusion die by melted PVC material in described a step, utilize screw extruder melted PVC material to be extruded from extrusion die, form catheter body.
It is an advantage of the current invention that the catheter of the present invention utilizes PVC to make, and after the coupling processing of conjugate solution, lubricity is more excellent.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
Claims (2)
