Abstract

The utility model discloses a urinary guide apparatus used for guiding a urethral catheter, which is composed of a sleeve pipe and an inner core, wherein, the inner core is movably sheathed inside the sleeve pipe, and a long notch is arranged on the whole body of the wall of the sleeve pipe. The utility model is simple in structure and convenient in operation, and can extend narrow urethra; the utility model assists the urethral catheter to insert into the urethra of the patient in one step, and shortens treatment time. The utility model avoids the train and side damages to the urethra caused by the repeated insertion of the urinary catheter, reduces infection of the patient's urinary system simultaneously, and reduces pain for the patient.

Description

Urinary canal guider

This utility model relates to a kind of medical apparatus and instruments, is used for urinary canal guider to the auxiliary catheter urethral catheterization of patient when relating in particular to a kind of Urology Surgery clinical treatment.

Along with the growth at people's age, especially arrived the old stage, urinary system is easy to generate pathological changes, and many old peoples suffer from urine retention, the frequent micturition due to prostate hyperplasia, the urethral stricture etc.The phenomenon that severe patient produces dysuria or can't urinate, thereby need import treatment with catheter.The medical catheter that adopts in the hospital has two chambeies or three chamber medical grade rubber catheters usually at present, and this catheter good springiness, softness can not damaged patient's organ pipe cortex.But also just because of this catheter softness.Patient for urethral stricture is not easy to be inserted in the urethra, and operator often need the repeated multiple times examination to insert, even undue force causes the pair damage in various degree of patient's urethra for insertion, brings unnecessary misery to the patient.

The purpose of this utility model provides a kind of easy and simple to handle, and auxiliary catheter once imports patient's urethra, avoids damaging patient's organ pipe surface, alleviates patient's misery, the urinary canal guider that patient is obtained medical treatment effectively fast.

The technical solution of the utility model is achieved in that

A kind of urinary canal guider that is used for auxiliary catheter importing, it is made up of a sleeve pipe (2), inner core (1), and its inner core (1) movable set is in sleeve pipe (2), and the system body has a long nick on the wall of sleeve pipe (2).

Inner core (1) forms a cylinder with sleeve pipe (2), the transverse section is a disk.

Can also movable set one jackscrew in the inner core (1).

Good effect of the present utility model is: simple in structure, easy to operate, can expand narrow urethra, auxiliary catheter once inserts in patient's urethra, shorten treatment time, avoid inserting stimulation and the secondary damage that causes urethra, reduce infection simultaneously, reduce the misery that causes to patient patient's urinary system with the examination of catheter repeated multiple times.

Below in conjunction with accompanying drawing this utility model is described further:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the cross-sectional view of Fig. 1 along the A-A direction,

By Fig. 1, shown in Figure 2, this urinary canal guider is made up of a sleeve pipe 2, inner core 1, and its inner core 1 movable set is in sleeve pipe 2, and the body of uniting on the wall of sleeve pipe 2 has a long nick makes sleeve pipe form a cover barrel so that sleeve pipe breaks away from catheter.In order not make the sleeve pipe gap edge scratch patient's organ pipe epidermis, inner core 1 forms a cylinder with sleeve pipe 2, the transverse section is a disk.The rear end that is provided with sleeve pipe handle 3, inner core 1 for easy to operate rear end at sleeve pipe 2 is provided with inner core handle 4.

During operation, earlier inner core cover is contained in the sleeve pipe, hand-held sleeve pipe handle, withstand the inner core handle, after slowly sleeve pipe being inserted urethra, slowly extract inner core again out, will have two forks with jackscrew then or the catheter of trident enters urethra by sleeve pipe, after treating that the position is determined, sleeve pipe is extracted out and can be treated by the breach on the sleeve pipe.

Claims

1, a kind of urinary canal guider that is used for auxiliary catheter importing, it is made up of a sleeve pipe (2), inner core (1), it is characterized in that inner core (1) movable set in sleeve pipe (2), and the system body has a long nick on the wall of sleeve pipe (2).

2, urinary catheter catheter according to claim 1 is characterized in that inner core (1) and sleeve pipe (2) form a cylinder, the transverse section is a disk.
