The disposable urine drainage catheter comprises a catheter 1, a catheter 11, a head 12, an expansion main body 13, a flat structure 2, a hollow catheter body 21, a guide wire perforation hole 3, a first cavity, a second cavity, a urination hole 5 and a partition plate 6.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

According to an embodiment of the present invention, as shown in fig. 1 and 2, there is provided a urethral dilator, including a bent dilating tube 1, wherein the dilating tube 1 has a structure with two closed ends and a hollow interior; a hollow pipe body 2 for guiding a wire channel is arranged in the expansion pipe 1, the hollow pipe body 2 penetrates through two ends of the expansion pipe 1, a wire guiding through hole 21 is formed at the end part of the expansion pipe 1, and the central axis of the hollow pipe body 2 is superposed with the central axis of the expansion pipe 1; be equipped with baffle 6 in the expansion pipe 1, first cavity 3 and second cavity 4 are cut apart into in 6 with the expansion pipe to the baffle, and cavity body 2 inlays in the centre portion of baffle 6, and the part that the tip of expansion pipe 1 corresponds first cavity 3 and second cavity 4 is equipped with urination hole 5.

The central axis of the hollow pipe body 2 coincides with the central axis of the expansion pipe 1, so that the bending consistency of the hollow pipe body 2 and the expansion pipe 1 is ensured, unnecessary bending of the guide wire is avoided, and the guide wire is ensured to be guided smoothly. And directly keep apart by 6 baffles and form first cavity 3 and second cavity 4, not only make things convenient for the preparation, play the effect of support to expansion pipe 1 moreover, improve expansion pipe 1's compressive strength, avoided because the urethra stenosis causes the extrusion to expansion pipe 1 and make expansion pipe 1 warp or fracture to play the stable effect of reinforcement to hollow body 2. The expanding pipe 1, the hollow pipe body 2 and the partition 6 can be integrally formed by adopting a mould.

The working principle of the urethral dilator is as follows: firstly, the bent expansion tube 1 is placed into a urethra to enter a bladder, in the process of expansion and placement, an operator can judge whether the urethra dilator is successfully placed or not by observing whether clear urine is discharged from the urine discharge holes 5 of the first cavity 3 and/or the second cavity 4, namely if the clear urine is discharged, the operator can determine that the urethra dilator is successfully placed, and after the operator places a guide wire into the bladder through the hollow tube body 2, the operator withdraws from the expansion tube 1 and then leads to an indwelling catheter or other instruments through the guide wire; if bloody urine or blood is discharged, an operator can insert a guide wire through the hollow tube body, then whether the guide wire enters the bladder is detected through ultrasound, and if the guide wire enters the bladder, the urethra dilator is successfully inserted; if the guide wire does not enter the bladder, the urethra dilator is determined to be unsuccessfully implanted, and an operator needs to stop the implantation operation and perform corresponding treatment so as to re-implant the urethra dilator, so that the operation efficiency can be improved, the pain and the wound of a patient are reduced, and the operation time is saved.

In the process of putting the urethral dilator, an operator can judge whether the urethral dilator is successfully put by observing whether clear urine is discharged from the urine discharge holes 5 of the first cavity 3 and/or the second cavity 4, namely if clear urine is discharged, the operator can determine that the urethral dilator is successfully put, and the operator can withdraw the urethral dilator after putting a guide wire into the bladder through the hollow tube body 2 and then guide to keep a catheter or other instruments through the guide wire; if bloody urine or blood is discharged, the operator can determine that the urethral dilator is unsuccessfully inserted, and the operator needs to stop the insertion operation and perform corresponding treatment so as to insert the urethral dilator again, so that the operation efficiency can be improved, and the operation time can be saved.

In the above embodiment, as shown in fig. 1, the extension tube 1 includes the curved head portion 11 and the extension body 12 communicating with the head portion 11, and the head portion 11 and the extension body 12 form an angle α of 30 ° and the head portion 11 is arc-shaped. The external diameter of expansion main part 12 and head 11 is the same, the end of expansion main part 12 is flat structure 13, wherein, the tip of flat structure 13 and the corresponding marginal perpendicular distance of expansion main part 12 can be 5mm, the diameter of flat structure 13 is 1cm, both can make things convenient for the operator to grip expansion pipe 1 like this, make things convenient for the operator to operate, thereby improve the comfort level of operation, can guarantee again that urethra dilator wholly has less volume, conveniently deposit, of course, flat structure 13 also can adopt other sizes, this embodiment does not do the strict limitation.

In the above embodiment, as shown in fig. 1, the urination hole 5 is located at the end of the flat structure 13, and the opening of the urination hole 5 is arranged downwards, so that the liquid discharged from the urination hole 5 can flow downwards, thereby preventing the liquid discharged from the urination hole 5 from splashing on the body or hand of the operator.

In the above embodiment, the diameter of the hollow tube 2 is 2mm, so that the guide wire can smoothly enter.

In the above embodiment, the dilating tube 1 is made of high temperature resistant stainless steel or synthetic metal material, which can be sterilized at high temperature, thereby ensuring the repeated use of the urethral dilator.

Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed above.
