As a preferable scheme, the anti-retrograde infection indwelling catheter is characterized in that the urethral catheterization channel is positioned in the central channel, and the inflation channel and the administration channel are respectively positioned on two sides of the catheter.
In the above-mentioned anti-retrograde infection indwelling catheter, as a preferable mode, the inflation channel and the administration channel are located in the interlayer wall of the catheter.
As another preferable mode, the length of the bladder area is preferably 8-11 cm.
As another preferable scheme, the diameter of the leakage hole is preferably 0.2-0.3 mm.
Has the advantages that: compared with the prior art, the utility model relates to a novel catheter, its most outstanding characteristics are provided with anti retrograde infection device in the urethra district, through set up the minimum weeping hole in a plurality of apertures on the pipe wall around the urethra district, and set up the passageway of dosing and the interface of dosing that links to each other with the urethra district at the catheter afterbody, as long as regularly squeeze into an amount of liquid medicine or flush fluid through the passageway of dosing, just can reach and wash for in the urethra, the purpose of dosing, thereby solved present nursing to keeping somewhere the catheter patient for a long time and only confine the urethral orifice to, can't wash in the urethra, the problem of disinfecting, the high phenomenon of urinary system retrograde infection that leads to because of keeping somewhere the catheter for a long time has greatly been reduced clinically, patient's misery has been alleviateed.

Detailed Description
In order to solve the problem that the clinical indwelling catheter causes high retrograde infection, the stress infection indwelling catheter is designed, and the utility model is described in detail with the accompanying drawings and the specific implementation mode.
As shown in figure 1, the utility model discloses a catheter is kept somewhere to anti retrograde infection, including the bladder district 3 and the urethra district 6 of catheter front end, whole catheter adopts high-quality silica gel to make, bladder district 3 length about 8-11cm, bladder district 3 is regional for keeping somewhere the catheter in the bladder, urethra district 6 is regional for being located the catheter in the urethra, the upper and lower both ends of urethra district 6 all adopt fine and close material to seal, the lower extreme and the administration channel 12 of urethra district 6 link to each other. The urinary bladder area 3 is provided with urine drainage holes 1 and an air bag 2, the two urine drainage holes 1 are used for draining urine, and the air bag 2 is inflated to fix the catheter to prevent falling. Urethra district 6 around be equipped with a plurality of weeping holes 4 on the pipe wall to make things convenient for liquid medicine or flush fluid to get into the urethra and play and dose or wash the effect, the aperture of weeping hole 4 is minimum (0.2 ~ 0.3mm), can reduce breeding of bacterium in the passageway on the one hand, on the other hand can form high-pressure environment, make flush fluid or liquid medicine spout in weeping hole 4.
The tail part of the catheter is sequentially provided with three interfaces, namely a urethral catheterization interface 7, an inflation interface 8 and a drug administration interface 9, wherein the urethral catheterization interface 7 is communicated with the urethral catheterization hole 1 of the bladder area 3 through a urethral catheterization channel 10 and is externally connected with a urine bag to drain urine to the outside of the body. The inflation interface 8 is communicated with the air bag 2 of the bladder area 3 through an inflation channel 11, and air is pumped into the air bag 2 at the top end of the channel in the bladder area 3 through the inflation channel 11 to play a role in indwelling and fixing the catheter. The administration interface 9 is connected with the lower end of the urethra region 6 through the administration channel 12, the top end of the administration channel 12 is connected with the lower end of the urethra region 6, the top end of the administration channel 12 is further provided with a one-way valve 5, so that the given medicine or flushing fluid can only flow to the leakage hole 4 of the urethra region from the administration channel 12 in one way, the backflow is avoided, and the administration or flushing purpose is achieved. The urethral catheterization channel 10 is positioned in the central channel, the inflation channel 11 and the administration channel 12 are respectively positioned at two sides of the urethral catheter, and the inflation channel 11 and the administration channel 12 are both positioned in the interlayer wall of the urethral catheter.
When the air bag type urethral catheter is used, the bladder area 3 of the urethral catheter is stretched into the bladder, certain air is injected from the inflation connector 8 by the hollow needle, enters the air bag 2 through the inflation channel 11, and is used for fixing the urethral catheter after the air bag 2 is inflated. When the catheter conducts urine, the switch is opened, and the urine in the bladder flows out of the body from the urine guide hole 1 through the urine guide channel 10. For patients with long-term indwelling catheters, regular urethral flushing nursing is needed when necessary, the specific method is that a medicine or flushing fluid is driven into the urethral region 6 from a drug administration interface 9 by using an empty needle, the medicine or the flushing fluid reaches the urethral region 6 through a single valve 5 along a drug administration channel 12, a one-way valve 5 can prevent the liquid medicine or the flushing fluid from flowing backwards, the tube cavity of the drug administration channel 12 is thick due to the fact that the diameter of a liquid leakage hole 4 on the tube wall around the urethral region 6 is small, a high-pressure environment can be formed in the urethral region 6, the flushing fluid or the liquid medicine is sprayed out from the liquid leakage hole 4, and therefore the urethral flushing or urethral killing effect is achieved, and the reverse infection rate of the urinary system caused by.
The above-mentioned embodiments are only described the preferred embodiments of the present invention, and are not limited to the concept and the protection scope of the present invention, and the technical solution of the present invention can be modified and improved by the ordinary engineers in the field without departing from the design concept of the present invention, and all should fall into the protection scope of the present invention.
