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] Such as figure 1 , figure 2 with image 3 As shown, the present invention includes a main catheter 1, a urinary hole 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 lower part of the urinary hole 2. There is an internal fixation balloon 4, the main catheter 1 is provided with a balloon cavity 5, one end of the balloon cavity 5 is connected with the internal fixation balloon 4, and the other end of the balloon cavity 5 is formed at the end of the catheter An independent balloon passage port 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 around the side wall of the main catheter 1 and used to prevent metal probes from passing through Break the protrusion 8 of the urinary catheter, the protrusion 8 is located at the upper part of the urinary hole 2 ...

Embodiment 2

[0031] Such as Figure 4 , Figure 5 with Image 6 As shown, the difference between this embodiment and the embodiment 1 is that the top of the main catheter 1 is located on the upper part of the urinary hole 2 and is also provided with an irrigation hole 9, and the main catheter 1 is provided with an irrigation channel 10, and the irrigation One end of the channel 10 is connected to the flushing hole 9, and the other end of the flushing channel 10 forms an independent flushing channel opening 11 at the end of the urinary catheter; the protrusion 8 is provided with four metal probes for preventing Slipping groove 12. The rest of the structure is the same as the first embodiment.

Embodiment 3

[0033] Such as Figure 7 , Figure 8 with Picture 9 As shown, the difference between this embodiment and the second embodiment is that the groove 12 is a ring around the guide wire channel. The rest of the structure is the same as the second embodiment.

[0034] When the urinary catheter of the present invention is used for urinary catheterization, if the patient's urethra is not diseased, the urinary 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 The first method: insert an elbow metal probe 13 with certain hardness and elasticity into the urinary catheter from the urine outlet 3 to increase the hardness of the catheter and change the curvature of the catheter head to make the catheter The urinary tube is formed in a shape similar to a urethral dilator, which is more in line with the physiological structure of the urethra, and is convenient to i...

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] Urinary catheterization is one of the most common clinical operations. At present, the catheters used in hospitals are usually soft catheters with equal diameter and uniform wall thickness made of materials such as rubber or silicone. However, for patients with senile prostatic hyperplasia, prostatitis, and urethral injury, due to changes in urethral course and curvature, ordinary catheterization methods often have varying degrees of difficulty in intubation. After intubation fails, bladder puncture and fistula are required Or use a metal urinary catheter, because the metal urinary catheter is inconvenient to retain, and the bladder puncture fistula is an emergency operation, which causes a lot of inconvenience in actual work. In order to reduce the patient’s pain and smoothly insert the urinary catheter, the following catheterization methods ar...
