[0002] A urinary catheter is a tube inserted into the bladder through the urethra to drain urine. It is inserted into the bladder through the urethra to drain urine, which is then drained into a urine bag connected to the catheter for collection.

[0003] In clinical practice, bladder irrigation is frequently required during urinary catheterization, especially in cases of cystitis, where doctors administer medication and achieve treatment through irrigation. Current techniques typically involve connecting the irrigation tubing to the urinary catheter using an injection needle, removing the existing urine bag from the catheter, and then inserting the needle into the catheter to inject fluid into the bladder for irrigation. However, the insertion and removal of the urine bag and the use of the injection needle are always inconvenient and pose a risk of injury to medical staff or patients.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0036] This invention provides a bladder irrigation catheter device, such as... Figures 1 to 7As shown, this invention solves the problem in existing technologies where the urine bag and injection needle need to be reinserted during bladder irrigation. Specifically, the bladder irrigation catheter device includes a main tube 1, a flow valve 2, and a branch tube 3. The main tube 1 is used to penetrate the bladder to drain urine and can also deliver irrigation medication into the bladder to irrigate it. The main tube 1 includes a first connecting end 11 that extends into the bladder and a second connecting end 12 located outside the body. The flow valve 2 is detachably installed on the first connecting end 11 to control the flow of irrigation medication from the main tube 1 to the bladder and the flow of urine from the bladder to the main tube 1. That is, when bladder irrigation is needed, the irrigation medication flows from the main tube 1 to the bladder; when irrigation is completed and the irrigation medication needs to be drained or urination is required, the irrigation medication and urine are controlled to flow from the bladder to the main tube 1 and finally drained from the main tube 1 to the outside of the body. The bifurcation tube 3 is detachably installed on the second connecting end 12. The end of the bifurcation tube 3 away from the second connecting end 12 is provided with a flushing connection port 32 and a urination connection port 33. A device for supplying flushing solution, such as an injection needle, is connected through the flushing connection port 32. The flushing solution is injected through the flushing connection port 32, and a urine bag is connected through the urination connection port 33. The flushing solution passes through the bifurcation tube 3, the main tube 1, and the diversion valve 2 in sequence to enter the bladder to flush it. When it is necessary to expel the flushing solution or urine, the flushing solution or urine passes through the diversion valve 2, the main tube 1, and the bifurcation tube 3 in sequence to enter the urine bag, where the urine bag collects the liquid.

[0037] Specifically, the bifurcated tube 3 includes a connector 31, a flushing tube 34, and a urination tube 35. The connector 31 is inserted into the second connecting end 12, and the connector 31 and the second connecting end 12 are press-fitted to prevent the connector 31 from falling out of the second connecting end 12 during use, thus affecting its use and causing flushing solution and urine to flow onto the patient, causing discomfort. The flushing tube 34 and the urination tube 35 are respectively connected to the connector 31. The flushing connection port 32 is located at the end of the flushing tube 34 away from the connector 31, and the urination connection port 33 is located at the end of the urination tube 35 away from the connector 31. At this time, the flushing tube 34 is used to deliver the flushing solution. When the flushing solution enters from the flushing connection port 32, it flows through the flushing tube 34, then flows to the connector 31, and then from the connector 31 to the main pipe 1 until it passes through the guide valve 2 and enters the bladder. The urination tube 35 is used to deliver urine and the flushing solution after flushing. That is, when it is necessary to drain urine and the flushing solution after flushing, the liquid flows through the guide valve 2 to the main pipe 1, and then from the main pipe 1 to the connector 31 and the urination tube 35, until it is discharged from the urination connection port 33.

[0038] To prevent the mixing of incomplete flushing solution with urine to be expelled and completed flushing solution, the connector 31 is equipped with a first branch pipe 311 and a second branch pipe 312. The first branch pipe 311 connects to the flushing pipe 34, and the second branch pipe 312 connects to the urination pipe 35. In this configuration, the incomplete flushing solution flows only within the flushing pipe 34 and the first branch pipe 311, while the urine and completed flushing solution flow only within the urination pipe 35 and the second branch pipe 312. This prevents the mixing of the completed flushing solution with the urine to be expelled and the completed flushing solution, thus avoiding infection and maintaining cleanliness and hygiene.

[0039] Similarly, to prevent the flushing solution, urine ready to be expelled, and the flushing solution from mixing within the main tube 1, the main tube 1 is equipped with a first branch tube 13 and a second branch tube 14. When the connector 31 is inserted into the second connector 12, the first branch tube 13 is connected to the first branch tube 311, and the second branch tube 14 is connected to the second branch tube 312. Therefore, when the flushing solution that has not yet completed flushing flows through the main tube 1, it will only flow within the first branch tube 13 until the flushing solution flows to the bladder through the guide valve 2. Conversely, when urine and the flushing solution that has completed flushing flow through the main tube 1, they will only flow within the second branch tube 14 until they flow through the second branch tube 312 and the urination tube 35 to be expelled from the body. This further ensures the cleanliness and hygiene of the catheter. Specifically, the diameter of the first branch tube 13 is smaller than that of the second branch tube 14. The smaller diameter of the first branch tube 13 increases the flushing force of the flushing solution, thus better flushing the bladder. The larger diameter of the second branch tube 14 allows for faster drainage of the flushing solution and the completed flushing solution, preventing fluid accumulation in the bladder and avoiding adverse effects on the patient.

[0040] In addition, to separate the first branch pipe 13 and the second branch pipe 14, the main pipe 1 is also provided with a main diaphragm 15 to separate the first branch pipe 13 and the second branch pipe 14, so as to avoid interference between them when liquid flows in the first branch pipe 13 and the second branch pipe 14. Therefore, a bifurcated diaphragm 314 is also provided in the connector 31 to separate the connecting first branch pipe 311 and the connecting second branch pipe 312, so as to avoid mutual interference between the connecting first branch pipe 311 and the connecting second branch pipe 312.

[0041] In order to better fix the bifurcation tube 3 inside the main tube 1, the connector 31 is provided with a connecting groove 313, and the main tube diaphragm 15 is inserted into the connecting groove 313, so as to enhance the fixing effect of the bifurcation tube 3 inside the main tube 1 and prevent the bifurcation tube 3 from falling out of the main tube 1 during the use of the catheter.

[0042] like Figures 5 to 7 As shown, the diversion valve 2 is equipped with a first one-way valve 21 and a second one-way valve 22. The first one-way valve 21 is connected to the first branch pipe 13 to control the flow of flushing solution from the first branch pipe 13 to the bladder. That is, at this time, the flushing solution that has not yet been flushed can only flow from the first branch pipe 13 to the bladder. Urine in the bladder and the flushing solution that has been flushed cannot flow from the bladder through the first one-way valve 21 to the first branch pipe 13, thus preventing the flushing solution that has not yet been flushed from mixing with urine and the flushing solution that has been flushed, which could cause infection and psychological discomfort. Figure 6 and Figure 7 The arrows in the diagram indicate the direction of liquid flow, i.e. Figure 6 This indicates that the flushing solution and urine that were not completely flushed, as well as the flushing solution that was completely flushed, should flow in the correct direction. Figure 7 This indicates that the flushing solution and urine were not completely flushed, or that the flushing solution that was completed was not flowing in the correct direction.

[0043] Specifically, the first one-way valve 21 includes a first valve body 211, a first valve disc 212, a first telescopic member 213, and a first permeable membrane 214. When the flushing solution that has not been flushed enters the first branch pipe 13, the first telescopic member 213 contracts, causing the first valve disc 212 to move towards the bladder, so that a gap is formed between the first valve disc 212 and the first valve body 211, so that the flushing solution that has not been flushed can flow into the bladder through the first one-way valve 21. When the urine in the bladder and the flushing solution that has been flushed flow into the first one-way valve 21, they will squeeze the first valve disc 212, causing the first telescopic member 213 to extend and causing the first valve disc 212 to move away from the bladder until the first valve disc 212 contacts the first valve body 211 without any gap, thus preventing the urine in the bladder and the flushing solution that has been flushed from flowing into the first branch pipe 13.

[0044] The second one-way valve 22 is connected to the second branch pipe 14 to control the flow of urine from the bladder to the second branch pipe 14. Specifically, by setting the second one-way valve 22, the fluid in the bladder can only flow through the second one-way valve 22 to the second branch pipe 14 until it is expelled from the body, instead of flowing back into the first branch pipe 13 through the first one-way valve 21, thus preventing infection. Specifically, the second one-way valve 22 includes a second valve body 221, a second valve disc 222, a second telescopic member 223, and a second permeable membrane 224. When urine and flushing solution in the bladder enter the second one-way valve 22 and need to be expelled promptly, the urine and flushing solution compress the second valve disc 222, causing the second telescopic member 223 to contract. This moves the second valve disc 222 away from the bladder, creating a gap between the second valve disc 222 and the second valve body 221 to facilitate the flow of urine. The flushing solution, after rinsing, flows into the second branch pipe 14 through the second one-way valve 22. When urine and the flushing solution tend to flow back to the second one-way valve 22, they compress the second valve disc 222, causing the second telescopic member 223 to extend and move the second valve disc 222 closer to the bladder until it contacts the second valve body 221 without any gaps, preventing backflow of urine and the flushing solution and allowing them to drain smoothly. At this point, the first telescopic member 213 and the second telescopic member can be components such as springs that change length under pressure.

[0045] Furthermore, to prevent the drainage valve 2 from falling off the first connecting end 11 during use, the drainage valve 2 is also provided with a drainage groove 23. The drainage groove 23 is located between the first one-way valve 21 and the second one-way valve 22, so that when the drainage valve 2 is installed on the first connecting end 11, the main diaphragm 15 is inserted into the drainage groove 23, thereby fixing the drainage valve 2 on the first connecting end 11 and preventing the drainage valve 2 from falling off and remaining in the bladder, which would have an adverse effect on the patient.

[0046] Once the catheter is inserted into the bladder, it needs to be secured within the bladder to prevent dislodgement. Therefore, the bladder irrigation catheter device also includes an inflation tube 4, and an air balloon 16 is fitted around the outer ring of the main tube 1. The air balloon 16 is connected to the irrigation tube 34. After the catheter is inserted into the bladder, the air balloon 16 is inflated through the inflation tube 4, causing the air balloon 16 to gradually expand until it blocks the internal urethral orifice in the bladder, thereby preventing the catheter from dislodgement from the internal urethral orifice. At this time, fluid exchange between the bladder and the outside occurs only through the catheter.

[0047] Therefore, when using the bladder irrigation catheter device of this application to irrigate the bladder, first install the diversion valve 2 on the first connecting end 11, install the branch pipe 3 on the second connecting end 12, and then insert the diversion valve 2 into the external urethral orifice, so that the diversion valve 2 and the main tube 1 enter the bladder along the urethra until the diversion valve 2 and the balloon 16 are both in the bladder. Then inflate the balloon 16 through the inflation tube 4. After inflation, connect the irrigation solution supply device to the irrigation connection port 32, connect the urine bag to the urination connection port 33, and start the irrigation solution supply device so that the irrigation solution flows through the irrigation tube 34, the first branch pipe 311, the first branch pipe 13 and the first one-way valve 21 into the bladder to irrigate the bladder. When the irrigation is completed, close the irrigation solution supply device so that the urine and the completed irrigation solution flow through the second valve, the second branch pipe 14, the second branch pipe 312 and the urination tube 35 and flow into the urine bag. The urine bag collects these liquids to complete the irrigation.

[0048] It should be understood that the application of this utility model is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
