Description
Technical field
This utility model relates to a kind of o urethral catheterization device, especially relates to a kind of painless automatic urethral catheterization device.
Background technology
The o urethral catheterization device that Hospitals at Present is used is a simple urethral catheterization sebific duct, external diameter is about at 5 millimeters, the front end that the urethral catheterization sebific duct inserts human body is provided with the air bag not connected with urinary pathway, rear end is provided with urinate mouth and airbag aeration mouth, the mouth of urinating communicates with urinary pathway, the airbag aeration mouth communicates with air bag by capillary tube, during use, per urethra inserts bladder, intravesical urine is flowed out through urinary pathway, for preventing landing, from the airbag aeration mouth, to airbag aeration, gas is assisted the softened junction of staying intravesical and urinary catheter mouth.Such o urethral catheterization device, the urethral catheterization sebific duct must be inserted into to intravesical from the urethral orifice of human body always, intubating length is longer, make patient that the distending pain sense be arranged, feel to feel bad very much and uncomfortable, and patient's urethra aperture varies, need to according to circumstances select the urethral catheterization sebific duct of different-diameter, sometimes patient's urethra has inflammation or the too soft importing difficulty of sebific duct, increases patient's misery.
The utility model content
The purpose of this utility model is, overcomes problems of the prior art, provides a kind of sebific duct insertion depth shallow, the painless automatic urethral catheterization device that insertion limit, limit is lubricated.
For solving above technical problem, a kind of painless automatic urethral catheterization device of the present utility model, comprise the urethral catheterization sebific duct, the front end of described urethral catheterization sebific duct is provided with the air bag not connected with urinary pathway, the rear end sidewall of described urethral catheterization sebific duct is connected with urinate mouth and airbag aeration mouth, the described mouth of urinating communicates with described urinary pathway, described airbag aeration mouth communicates with described air bag by capillary tube, it is characterized in that: the rear end of described urethral catheterization sebific duct also is provided with the seal wire entrance with urinary pathway coaxial line and perforation, described seal wire entrance inwall is provided with the seal wire nut coordinated with seal wire, the spring seal wire is arranged in urinary pathway, described seal wire stretches out outside urinary pathway and end is coated with lubricant head towards the front end of human body, described lubricant head middle part is provided with oilhole, the rear end of described seal wire is stretched out outside described urethral catheterization sebific duct and is connected with the seal wire driving device, the part cover that described seal wire stretches out the urethral catheterization sebific duct has corrugated tube, be provided with lubricating oil pipe along the seal wire axis in described seal wire, the front end of described lubricating oil pipe is connected with the oilhole of described lubricant head, and the rear end of described lubricating oil pipe is provided with the lubricating oil injection port.
With respect to prior art, this utility model has been obtained following beneficial effect: this painless automatic urethral catheterization device in use, only the urethral catheterization sebific duct need be inserted to approximately 3 centimetres of human bodies, to airbag aeration, itself and urethral orifice are coincide and prevent seepage, the seal wire driving device turns the seal wire in the urethral catheterization sebific duct, make its end enter bladder and realize urethral catheterization, because the external diameter of seal wire is little more a lot of than the external diameter of urethral catheterization sebific duct, and advance in the shape of a spiral under the drive of motor, be easy to overcome resistance, when seal wire advances, the lubricant head of lubricating oil pipe by its end synchronously discharges oil preparation and is lubricated, can not cause patient's sense of discomfort.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation, and accompanying drawing only provides reference and explanation use, non-in order to limit this utility model.
The structural representation that Fig. 1 is the painless automatic urethral catheterization device of this utility model.
In figure: 1. lubricant head; 2. lubricating oil pipe; 2a. lubricating oil injection port; 3. seal wire; 4. air bag; 5. urethral catheterization sebific duct; 6. seal wire entrance; 7. airbag aeration mouth; 8. seal wire nut; 9. the mouth of urinating; 10. corrugated tube; 11. seal wire driving device.
The specific embodiment
As shown in Figure 1, painless automatic urethral catheterization device of the present utility model, the front end of urethral catheterization sebific duct 5 is provided with the air bag not connected with urinary pathway 4, the rear end sidewall of urethral catheterization sebific duct 5 is connected with urinate mouth 9 and air bag inflation inlet 7, the mouth 9 of urinating communicates with the urinary pathway of urethral catheterization sebific duct 5, and airbag aeration mouth 7 communicates with air bag 4 by capillary tube.The rear end of urethral catheterization sebific duct 5 also is provided with the seal wire entrance 6 with urinary pathway coaxial line and perforation, seal wire entrance 6 inwalls are provided with the seal wire nut 8 coordinated with seal wire 3, spring seal wire 3 is arranged in urinary pathway, adopt stainless steel material, external diameter adopts 2.5 millimeters, pitch adopts 1 millimeter, its front end towards human body stretches out outside urinary pathway and end is coated with lubricant head 1, the leading section of seal wire 3 is against on the bottom surface of lubricant head 1, the rear end of seal wire 3 is stretched out outside urethral catheterization sebific duct 5 and is connected with seal wire driving device 11, and the part cover that seal wire 3 stretches out the urethral catheterization sebific duct has corrugated tube 10.
