Description

Prostate urethra positioning flushing pipe

Technical Field

The utility model relates to a drainage catheter, in particular to a prostate urethra positioning and washing tube.

Background

In the local treatment of chronic prostatitis, the perfusion and drainage catheter used at present has a structure of adopting double air bags and three tube cavities, for example, a double-bag three-cavity prostate perfusion and drainage catheter disclosed in the patent No. 97224826.9, the catheter comprises three tube cavities and two air bags, namely a shoulder-off neck air bag tube cavity, a bulbourethral air bag tube cavity, a medicine injection tube cavity, a bulbourethral air bag and a shoulder-off neck air bag. When the double-bag three-cavity prostate perfusion drainage tube is used, the double-bag three-cavity prostate perfusion drainage tube is firstly inserted into the urethra of a patient, the position between the two air bags is positioned at the prostate part of the urethra, then air is perfused into the two air bags, and after the bulboperineal urethra air bag and the bladder neck air bag are filled, the prostate section of the urethra forms a relative blind cavity. Although the drainage catheter provides a new method for local flushing and drainage for treating prostatitis, the bladder neck air bag is utilized to seal the bladder neck, so that the perfused liquid medicine is not easy to flow back to the bladder, the clinical practice shows that the sealing effect of the bladder neck air bag for preventing the liquid medicine from entering the shoulder to be taken off is not ideal, thereby influencing the local perfusion pressure of the prostate section of the urethra and the treatment effect of flushing and drainage. After the perfusion and drainage operation is started, the liquid medicine can impact the front end shoulder to detach the neck air bag along the catheter by virtue of pressure and enable the neck air bag to swing left and right, and the bladder neck air bag swings left and right to provide an opening force for the bladder neck, so that the local perfusion pressure at the prostatic section of the urethra is reduced, and meanwhile, the sphincter of the bladder neck can not be effectively contracted and closed; thus, the bladder neck balloon has limited sealing effect on the prostatic segment of the urethra. In addition, because the catheter comprises three lumens and two air bags, compared with the catheter which only comprises two lumens and one air bag, the diameter of the catheter is increased, materials are wasted, the production process is also complicated, the production cost is also increased, and the pain of patients is also increased when the catheter is used. In addition, because different people, the length distance of urethra prostate section is different, and the interval of two gasbags on the pipe is fixed, can not design a honeycomb duct according to everyone, like this, the fixed interval of two gasbags also can influence the closed effect of two gasbags to urethra prostate section.

Therefore, 2006100364605 discloses a prostate urethra medicine injection washing drainage tube, which comprises a tube body, wherein two tube cavities are arranged in the tube body: the medicine is injected to wash the drainage tube cavity and the bulbourethral balloon cavity; an air bag: the front end opening of the cavity of the bulboperineal urethra balloon is communicated with the bulboperineal urethra balloon; the front end opening of the medicine injection flushing drainage tube cavity is arranged on the tube body wall close to the front end of the tube body in front of the bulboperineal urethra balloon and communicated to the outside of the tube body; the distance between the front opening of the drug injection flushing drainage tube cavity and the front opening of the bulbourethral balloon tube cavity is 1.0cm-3.0cm. The catheter eliminates a tube cavity of a shoulder-off neck air bag and a shoulder-off neck air bag in the catheter in the prior art, reduces the diameter of the catheter, relieves the pain of a patient and has better sealing effect. When in use, the drainage tube is firstly inserted into the urethra of a patient, the bulboperineal urethra balloon enters the bladder, then the balloon is inflated, the bulboperineal urethra balloon is pulled and fixed on the shoulder to take off the neck opening after the inflation, and the scale on the catheter at the urethral opening is recorded. Then, the air sac releases air, the catheter is pulled out by 6cm according to the urethral orifice scale, and the bulbourethral air sac is inflated again. At this time, the opening at the front end of the drug-filled irrigation drainage tube cavity is positioned at the prostatic urethra section, and meanwhile, the prostatic urethra section also becomes a relatively blind cavity. Then the medicine is injected to wash the drainage tube cavity, so that inflammatory secretion in the prostatic gland can be drained into the urethra and discharged, or can be discharged out of the body along with urine later. Because, its injection washes the front end opening of drainage tube chamber and establishes before the bulbourethral gasbag, consequently, pull out 6 centimetres with the pipe outwards according to urethral orifice scale, need inflate in the bulbourethral gasbag once more, complex operation, the gasbag location back for the first time, the distance that needs pull out the pipe backward is 6CM, pull out the distance overlength, can cause user's discomfort on the one hand, the total length of on the other hand drainage tube needs longer, consequently, one kind makes the operation simpler, can shorten further reduce cost of catheter length, the convenient prostate urethra portion location washing pipe that washes simultaneously becomes the target that technical staff in this field pursues.
