Problems solved by technology

Even if the metal dilator is successfully dilated, when the urinary catheter is inserted because of the hard texture of the stenotic scar, the urinary catheter often folds, bends, and cannot pass through the stenosis smoothly. The end lumen is thinner, and the expansion effect is limited, only limited to the range of its lumen diameter

Embodiment 1

[0032] A urethral dilatation and drainage device, comprising a urethral drainage dilation catheter, an inner sheath 5, a guide wire 6, and a pressure measuring device 4; the urethral drainage dilation catheter includes a tube head 1, a tube body 2, and a tube tail 3, with Guide hole 101, the tube body 2 is provided with a drainage hole 201 near the tube head 1, the tube body 2 below the drainage hole 201 is covered with a first air bag 202 and a second air bag 203, and the inner wall of the tube body 2 is provided with a first inflatable Channel 204 and second inflation channel 206; tube tail 3 includes a urine outlet tube 304, a first balloon tube 301 and a second balloon tube 302, the bottom end of the first balloon tube 301 is provided with a conduction valve 305, and the first balloon tube 201 passes through The first inflation channel 204 communicates with the first air bag 202, and the second air bag tube 302 communicates with the second air bag 203 through the second inf...

Embodiment 2

[0040] A method for using a urethral dilation and drainage device, comprising the following steps:

[0041] 1) First insert the curved hollow inner sheath 5 into the urethral drainage dilation catheter, insert the guide wire 6, and lead out the front end of the guide wire 6 from the guide hole 101 of the tube head 1 of the urethral drainage dilation catheter;

[0042] 2) Hold the tail 3 of the urethral drainage dilation catheter and insert it into the urethra. When reaching the position of the bladder neck, continuously insert and insert the guide wire 6 to find the contracture and narrow bladder neck;

[0043] 3) After the guide wire 6 is successfully inserted, firmly hold the catheter and the inner sheath 5, and insert it into the bladder according to the physiological curvature of the male urethra until urine flows out;

[0044] 4) Pull out the guide wire 6 after seeing the urine flow out, pull out the inner sheath 5, use a graduated syringe to inflate the first balloon 202 b...

Abstract

The invention discloses a urethral dilatation draining device and a using method. The urethral dilatation draining device comprises a urethral dilatation catheter, an endotheca, a guide wire and a pressure measuring device. The urethral dilatation catheter comprises a catheter head, a catheter body and a catheter tail. The middle of the catheter head is provided with a guide hole. The side face of the catheter body is provided with a side hole. The catheter body below the side hole is covered by two air bags. The endotheca is a hollow bended plastic structure and the top end is provided with a wire guide hole. The urethral dilatation draining device can be used as a normal urinary catheter on the one hand, and accurately passes through a contractured narrow bladder neck under the guide of the guide wire and the support of the hollow endotheca about a patient with the contractured narrow bladder neck after the prostate or bladder neck operation on the other hand, and accurately passes through a pressure-dilated narrow part after placed in the bladder neck. The dilated contracture scar is prevented from retracting and recovering, the pain of the patient is relieved, and the treatment for the patient is more convenient.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a urethral dilatation and drainage device and a usage method. Background technique [0002] Benign prostatic hyperplasia (BPH) is the most common disease among elderly men, and about 30% of patients need transurethral resection of the prostate. Bladder neck contracture is one of the common complications after resection of the prostate. Often this kind of contracture narrowing will appear "pinhole-like" changes, and the bladder neck is contracted and narrowed into a pinhole-like gap. Generally, metal dilators can be used for clinical expansion. If there is a little carelessness, a "false tract" will appear, and even the rectum will be damaged, resulting in serious consequences. Even if the metal dilator is successfully dilated, when the urinary catheter is inserted because of the hard texture of the stenotic scar, the urinary catheter often folds, bends, and cannot pass through th...
