Description

Multipurpose urethra dilator suitable for difficult catheterization patient

Technical Field

The utility model relates to a medical instrument, in particular to a multipurpose urethral dilator suitable for patients with difficult catheterization.

Background

Catheterization is one of the basic operations that clinical medical personnel must be skilled and mastered, and the catheterization by placing the air sac urinary catheter is simple and convenient and is suitable for most patients. However, patients with lower urinary tract obstruction such as urethral stricture, prostatic hyperplasia, bladder neck contracture and the like often fail to pass through the obstructed urethra because the urinary duct is unable to pass through the obstructed urethra, and the urinary duct is clinically called difficult urethral catheterization;

the prior art adopts the following modes:

1. for patients with difficult catheterization, the urethral catheterization is directly performed after urethral dilatation, and the clinical failure rate is higher.

2. The strength of the catheter is increased by inserting the metal wire-shaped probe into the catheter, but the problems that the metal wire-shaped probe is matched with the type of the catheter, the metal wire-shaped probe is soft and shapeable but has insufficient strength, the standard wire-shaped probe is not available and needs to be manufactured by a user, and the failure rate is still high are solved.

3. The catheterization after the ultra-smooth guide wire is kept under the endoscope has high success rate, but needs equipment guarantee and has higher cost.

Therefore, a new urinary catheterization apparatus is needed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a multipurpose urethra dilator suitable for patients with difficult urethral catheterization, which aims to solve the problem that how to carry out accurate, effective and safe catheterization on patients with difficult urethral obstruction (urethral stricture, prostatic hyperplasia and bladder neck contracture) clinically combined difficult urethral catheterization and solve the problem that patients with bladder tumors combined urethral stricture can not carry out bladder perfusion treatment due to difficulty in catheterization.

The utility model discloses a following technical scheme realizes above-mentioned purpose:

the utility model discloses an expander body and perfusion ware, the one end of expander body is most advanced segmental arc, the other end of expander body is the linkage segment, the expander body is the hollow tube, the most advanced segmental arc tip of expander body is most advanced hole, the linkage segment of expander body sets up the connecting hole, the connecting hole with the connection can be dismantled to the perfusion ware.

Further, the length of the dilator body is 170-200 mm. The arc curvature radius of the arc-shaped section of the tip is 100-120mm, and the length of the arc-shaped section of the tip is 30-50 mm. The caliber of the tip hole is 2.7mm-8 mm. The connecting pipe is 50mm in length, 6mm in diameter and 4mm in inner diameter and is matched with the perfusion apparatus interface.

The utility model can carry out the conventional urethral dilation treatment; meanwhile, aiming at the patients with difficult urethral catheterization, the ultra-smooth guide wire is reserved after the urethral dilator is placed into the bladder through the special hollow design in the urethra dilator, the urethral catheter is safely and effectively inserted under the guide of the guide wire, and the pain and urethral injury of the patients caused by the operation of replacing the urethral dilators with different models are reduced; for bladder tumor patients with urethral stricture complicated with urethral catheterization difficulty, the function of the bladder perfusion chemotherapeutic drug can be satisfied.

The beneficial effects of the utility model reside in that:

the utility model relates to a be suitable for difficult catheterization patient's multipurpose urethra expander, compared with the prior art, the utility model discloses not only can carry out conventional expansion treatment to constrictive urethra of blocking, can assist medical personnel to carry out the accurate catheterization processing under the seal wire guide to the special patient crowd of catheterization difficulty moreover to bladder tumour patient to merging the narrow catheterization difficulty that leads of urethra, can satisfy the function that the bladder pours into the chemotherapy medicine.
