Problems solved by technology

At present, the most simple and effective method is urinary catheterization, but the general urinary catheter is relatively soft. When the prostatic hyperplasia severely compresses the urethra or causes urethral stricture, it often leads to catheterization failure, and only cystostomy can be performed to drain urine. fluid, not only brought great pain to the patient, but also increased the economic burden. In order to solve this problem of catheterization, based on years of clinical experience, a urethral expansion catheter was invented.

Embodiment Construction

[0014] Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment includes an outer sheath 2 and an obturator 1 placed in the outer sheath 2 , and the cross section of the outer sheath 2 is a C-shaped hollow sleeve. The obturator 1 is a solid cylinder, the end of the cylinder is blunt, and the outer sheath 2 is a stainless steel hollow sleeve. The obturator 1 is 1 cm longer than the outer sheath 2 .

[0015] When in use: the patient lies supine, lifts the penis with the left hand, holds the urethral expansion catheter of the present invention in the right hand, inserts it into the posterior urethral stricture along the urethral opening, presses down the obturator 1, pushes it to the bladder while expanding, and injects water into the air bag After the urinary catheter is enlarged and fixed, the distal end of the catheter tube is pulled out through the C-shaped notch of the outer sheath, and withdraws from the outer sheath 2 to complete the...

Abstract

The invention discloses a urethral catheterication device used in a urological department, in particular to a urethra dilator. The urethra dilatation catheter comprises an epitheca and a hole closing device arranged in the epitheca, and is characterized in that the cross section of the epitheca is C-shaped hollow sleeve. The invention has the beneficial effect that the urethra dilatation catheter can be pushed into a bladder while dilating; a balloon catheter is placed into the bladder from the epitheca after the hole closing device is pulled out; water is injected into the balloon to be dilatated to fix the catheter; and the far end of the catheter is pulled out from the epitheca to finish urethral catheterication.

Description

(1) Technical field [0001] The invention relates to a urinary catheterization device for urology, in particular to a urethral dilator. (2) Background technology [0002] Acute urinary retention is the most common emergency in urology, and it is more common in patients with benign prostatic hyperplasia and urethral stricture. At present, the most simple and effective method is urinary catheterization, but the general urinary catheter is relatively soft. When the prostatic hyperplasia severely compresses the urethra or causes urethral stricture, it often leads to catheterization failure, and only cystostomy can be performed to drain urine. Liquid, not only brings great pain to the patient, but also increases the economic burden, in order to solve this catheterization problem, according to many years of clinical experience, specially invented the urethral expansion catheter. (3) Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the...
