Abstract
The utility model relates to a resistance-free urinary catheter. The utility model is composed of a flexible outer catheter and a supporting guide rod which is arranged in the outer catheter. The utility model combines rigidity and flexibility to cause the utility model to be conveniently operated by medical care personnel to cause the utility model to be inserted into a patient's urethra, and the urethra can not be injured by the utility model. Simultaneously, the supporting guide rod can be extracted conveniently, and the outer catheter is retained in the urethra to carry out retention catheterization. The resistance-free urinary catheter has the advantages of simple structure and convenient operation; the utility model is suitable for patients who have urethrostenosis symptom or prostatomegaly symptom.
Description
This utility model relates to a kind of medical catheter, particularly a kind of without hindrance catheter.
At present, widely used clinically catheter is the ordinary urethral catheter of being made by elastomeric material mostly, its end sidewalls of inserting an end of bladder of this catheter is provided with a urethral catheterization hole, can be connected with urinals such as urinals and be positioned at an external end, though this catheter has certain flexibility, easy damaged urethra not during use, but be difficult for inserting, thereby for operation of medical workers is brought certain difficulty, particularly more can't use for some urethral strictures or prostate hyperplasia patient, once had and a kind ofly made and the catheter identical,, be easy to insert urethra though it has overcome the deficiency of above-mentioned rubber urinary catheter to a certain extent with said structure by metal material, and be suitable for urethral stricture or prostate hyperplasia patient and use, but very easily damage urethra, and only can not keep as a urethral catheterization.
The purpose of this utility model is to provide a kind of without hindrance catheter, its not only simple in structure, easy operating, and, easy damaged urethra not, but and retention catheterization.
Its concrete solution is: mainly constitute this catheter by outer catheter and support guide rod, and, outer catheter is one to which is provided with the flexible pipe in urethral catheterization hole, support guide rod is arranged in the outer catheter, and the length of outer catheter should be less than the length of support guide rod, so that medical personnel are convenient to insert urethra when the patient is carried out urethral catheterization, and can easily support guide rod be taken out behind the complete operation.
This utility model is owing to be provided with a support guide rod in flexible outer catheter, make this urethral catheterization tube steel gentle double mutually, thereby that when both being convenient to medical personnel and operating it is had no resistance inserts patient's urethra, can damage not arranged again to urethra, simultaneously, also can extract support guide rod easily, only outer catheter is trapped in and implement retention catheterization in the urethra, this catheter is simple in structure, easy to operate, is particularly suitable for urethral stricture or prostate hyperplasia patient and uses.
In conjunction with the accompanying drawings this utility model is described in detail below by embodiment:
Accompanying drawing is a structure chart of the present utility model.
In the accompanying drawing, outer catheter (2) is a flexible pipe of being made by elastomeric material, and, the sidewall that outer catheter is inserted bladder one end is provided with a urethral catheterization hole (1), support guide rod (3) is positioned at outer catheter (2), and outer catheter is provided with a convenient handle (4) that extracts, and in addition then, this support guide rod (3) is made by metal material.
During use, after an end of this catheter was inserted patient's bladder, operator can extract support guide rod out by the handle of support guide rod one end from outer catheter, carried out retention catheterization in patient's body and outer catheter (2) is trapped in.
Claims (1)
1, a kind of without hindrance catheter, it is characterized in that mainly constituting, and outer catheter is one to which is provided with the flexible pipe of urethral catheterization hole (1) by outer catheter (2) and support guide rod (3), support guide rod (3) is arranged in the outer catheter (2), and the length of outer catheter should be less than the length of support guide rod.
