Problems solved by technology

However, in the prior art, the front end of the urinary catheter is closed, and the operator needs to puncture a hole on the top of the urinary catheter to pass through the guide wire, which is inconvenient to operate, wastes time, and may easily cause unnecessary acupuncture hurt
Moreover, when the first catheterization method is used, the metal bougie has high hardness and is easy to break through the catheter, causing urethral damage to the patient, or even physical injury such as urethral perforation, which increases the risk of catheterization

Embodiment 1

[0028] like figure 1 , figure 2 and image 3 As shown, the present invention includes a main catheter 1, a urinary catheter 2 on the top side wall of the main catheter 1, and a urine outlet 3 at the end of the main catheter 1, and is characterized in that: the top of the main catheter 1 is located at the bottom of the catheter 2. There is an internally fixed airbag 4, and the main catheter 1 is provided with an airbag lumen 5, one end of the airbag lumen 5 is connected to the internally fixed airbag 4, and the other end of the airbag lumen 5 is formed at the end of the urinary catheter Independent airbag channel opening 6, the top of the main catheter 1 is provided with a guide wire channel 7 for inserting a guide wire, and the guide wire channel 7 is provided with a guide wire channel 7 that is connected to the side wall of the main catheter 1 and is used to prevent metal bougies from penetrating. The protrusion 8 of the broken urinary catheter, the protrusion 8 is located...

Embodiment 2

[0031] like Figure 4 , Figure 5 and Image 6 As shown, the difference between this embodiment and Embodiment 1 is that: the top of the main catheter 1 is located on the upper part of the catheter hole 2 and is also provided with a flushing hole 9, and the main catheter 1 is provided with a flushing cavity 10, and the flushing One end of the lumen 10 is connected to the flushing hole 9, and the other end of the flushing lumen 10 forms an independent flushing channel opening 11 at the end of the catheter; four protrusions are provided on the protrusion 8 to prevent the metal bougie from Slip groove 12. All the other structures are the same as in Example 1.

Embodiment 3

[0033] like Figure 7 , Figure 8 and Figure 9 As shown, the difference between this embodiment and Embodiment 2 is that the groove 12 is annular around the guide wire channel. All the other structures are identical with embodiment 2.

[0034] When using the urinary catheter of the present invention for catheterization, if the patient’s urethra has no pathological changes, the catheter can be directly inserted into the bladder through the urethra for catheterization. If the patient’s urethra becomes longer, thinner and twisted, there are three operations Way, the first one: insert an elbow metal bougie 13 with a certain hardness and elasticity into the catheter from the urine outlet 3, increase the hardness of the catheter and change the curvature of the catheter head, so that the catheter The urinary catheter forms a shape similar to a urethral dilator, which is more in line with the physiological structure of the urethra and is convenient for insertion. The head of the e...

Abstract

The invention discloses a catheter comprising a main conduit, the catheter and a urine outlet, wherein the catheter is arranged on the side wall of the top end of the main conduit, and the urine outlet is arranged on the tail end of the main conduit; the top end of the main conduit is positioned on the lower part of a catheterization hole and is provided with an inner fixed air sac; the main conduct is provided with an air sac cavity; one end of the air sac cavity is connected with the inner fixed air sac, and the other end of the air sac cavity forms an independent air sac path port on the tail end of the catheter; the top end of the main conduit is provided with a conducting wire path for inserting a conducting wire; the periphery of the conducting path is provided with bulges which are connected with the side wall of the main conduit and are used for preventing a metal bougie from breaking the catheter; the bulges are positioned on the upper part of the catheterization hole and form a whole with the top end of the main conduit; and the bulge is provided with one or a plurality of grooves for preventing the metal bougie from slipping. The invention has simple structure, reasonable design, perfect function, convenient operation, safe and reliable use, low production cost, good using effect and convenient popularization and use.

Description

technical field [0001] The invention relates to a medical appliance, in particular to a urinary catheter. Background technique [0002] Catheterization is one of the most common clinical operations. The catheters currently used in hospitals are usually flexible catheters with equal diameters and uniform wall thickness made of materials such as rubber or silica gel. However, for patients with senile benign prostatic hyperplasia, prostatitis, and urethral injury, due to changes in the course and curvature of the urethra, it is often difficult to intubate in different degrees with ordinary catheterization. Or use a metal catheter for urinary catheterization, because the metal catheter is inconvenient to keep, and cystocentesis is an emergency operation, which causes a lot of inconvenience in actual work. In order to reduce the pain of the patient and insert the urinary catheter smoothly, the following catheterization methods are usually used during on-site operations: 1. Inser...
