Embodiment 1

[0020] Embodiment 1: refer to figure 1 — figure 2 , is a structural schematic diagram of Embodiment 1 of the present invention, including a catheter body 6, a catheter tip 1, a catheter hole 2, a catheter connector 8, a catheter outer port 10, an inflatable tube 7, and an inflatable nozzle 9 , catheter balloon 3, flushing nozzle mouth 11, flushing pipe 12 and the three-chamber urinary catheter that flushing pipe outlet 13 forms, on the urinary catheter body 6 above catheter balloon 3, be provided with constriction 4, constriction The diameter of the urinary catheter body below 4 is less than the diameter of the catheter body 6 above the constriction 4, and a split groove 5 is arranged between the neck constriction 4 and the catheter connector 8, and the length of the split groove 5 is the same as that of the human urethra. The lengths are compatible, after the catheter body 6 is inserted into the urethra, the split groove 5 is in the urethra, because the catheter body 6 is m...

Embodiment 2

[0021] Embodiment 2: refer to image 3 , is a schematic structural view of Embodiment 2 of the present invention. Compared with Embodiment 1, the difference of Embodiment 2 is that a split film 14 is provided outside the split groove 5, which not only does not affect the expansion and contraction of the urinary catheter body 6 , and the tightness is also better, even if the split groove 5 leaks out of the urethra, it does not affect the normal use of the catheter, and the practicability is stronger.

Embodiment 3

[0022] Embodiment 3: refer to Figure 4 , is a structural schematic diagram of Embodiment 3 of the present invention. Compared with Embodiment 2, Embodiment 3 is different in that: a connecting pipe 15 connected to the inside is provided on the outside of the catheter joint 8, and in the connecting pipe 15 A guide wire body 16 is provided, and a guide wire body joint 18 is provided at the outer end of the guide wire body 16, and an elastic film 17 is arranged between the guide wire body joint 18 and the outer end of the connecting pipe 15, which not only has the function of sealing, but also It has great elasticity, and it can be used to dredge the catheter and prevent the blockage of the catheter by pinching the guide wire joint 18 by hand and pumping back and forth. The traditional method of flushing the catheter with liquid or gas will block the catheter The dirt of the urinary catheter is washed into the bladder, and it is difficult to discharge it again. In this embodimen...

Abstract

The invention discloses a multifunctional catheter. A necking is arranged, above a catheter air bag, on a catheter body, and a rift trough is formed between the necking and a catheter adapter so that the catheter can retract to enter a urethra. Meanwhile, a thinner deputy catheter is arranged, and not only can the deputy catheter be used for dredging the catheter, but the deputy catheter can be used as a spare catheter. An outer air bag pipe communicated with an inflation pipe is arranged on the side surface of the inflation pipe, and an outer air bag is arranged on the outer air bag pipe and can be used for observing the pressure of an inner air bag. Compared with the prior art, not only does the multifunctional catheter have the function of existing three-cavity catheters, but the multifunctional catheter has the function of changing the diameter, and thus the multifunctional catheter is applicable to different patients; the multifunctional catheter has the effect of not only dredging the catheter but a spare catheter; besides, the multifunctional catheter has the effect of preventing the inner air bag of the catheter from not fully entering a urinary bladder or preventing the catheter from folding in the urethra; not only is the catheter more convenient to use, but multifunction of the catheter is achieved.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a multifunctional urinary catheter. Background technique [0002] Urinary catheter is a pipeline made of natural rubber, silicone rubber or polyvinyl chloride (PVC). It can be inserted into the bladder through the urethra to drain urine. After the catheter is inserted into the bladder, there is a tube near the head of the catheter. The balloon-fixed urinary catheter stays in the bladder and is not easy to come out, and the drainage tube is connected to the urine bag to collect urine. It is mainly suitable for: 1. Urinary disorders caused by various reasons, 2. Specific operations, such as: abdominal cavity, urinary tract, 3. It is necessary to record the urine volume per unit time. It is a medical device commonly used in hospitals. At present, with the continuous development of medical devices, the urinary catheter has developed from a single tube in the past to the current one. D...
