Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a kit for bladder irrigation. Background Technology

[0002] Bladder cancer is one of the most common malignant tumors of the urinary system, ranking 7th in incidence among male malignant tumors. A large number of bladder cancer patients undergo surgical treatment each year. Early-stage bladder cancer can be treated with transurethral resection of bladder tumor (TURBt). TURBt is a common treatment for bladder cancer, but various complications can occur postoperatively, the most common being bleeding. Bleeding is more likely to occur, especially with multiple tumors, large surgical areas, or deep resections reaching the bladder muscle layer. Literature reports that the incidence of post-TURBt bleeding is close to 10%.

[0003] For minor bleeding, methods such as applying hemostatic drugs and continuous bladder irrigation can reduce the time blood remains in the bladder and prevent the formation of blood clots. However, the distal orifice of a three-lumen catheter is very small and easily blocked by tissue fragments and blood clots. If irrigation is inadequate, blood can easily clot and remain inside the bladder, making it difficult to drain through the catheter. This can also cause repeated catheter blockages, increasing the risk of bladder tamponade and massive bleeding.

[0004] Clinically, when doctors discover urinary catheter obstruction in patients after transurethral resection of the cystostomy (TURP), they often attempt to flush the catheter with a syringe at the bedside to aspirate small tissue fragments or blood clots. However, this method is limited by the diameter of the catheter tip, and the suction force of the syringe is also limited. Once a blood clot forms, most patients have to undergo a second surgery, returning to the operating room for electrocoagulation hemostasis and flushing of the blood clot.

[0005] Therefore, based on extensive clinical experience and practical application, we designed a three-piece device for bladder irrigation. The shape of the irrigation tube at the front conforms to the natural curvature of the urethra, making it easy to insert into the bladder even for elderly male patients with severe benign prostatic hyperplasia. Moreover, the device uses a compressible irrigation balloon, which can provide sufficient irrigation and suction power, allowing tissue fragments and blood clots in the bladder to be suctioned out at the bedside in the ward, greatly reducing the risk of secondary surgery for patients. Utility Model Content

[0006] The purpose of this invention is to provide a kit for bladder irrigation to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A bladder irrigation kit includes an irrigation tube conforming to the physiological curvature of the urethra, a fluid passage inside the irrigation tube, a side hole at the head of the irrigation tube communicating with the fluid passage, and a supply component and an irrigation component at the tail of the irrigation tube. The supply component is used to provide irrigation fluid, and the irrigation component is used to flush the irrigation fluid into the bladder through the fluid passage and to aspirate tissue fragments or blood clots generated after bladder irrigation to the outside of the body.

[0009] As a further preferred embodiment of this utility model: a three-way valve connected to the tail end of the flushing pipe is connected to the liquid flow channel, and the three-way valve is connected to the liquid supply component and the flushing component.

[0010] As a further preferred embodiment of this utility model: the fluid supply assembly includes a saline bag, which is connected to a three-way valve via a connecting tube.

[0011] As a further preferred embodiment of this utility model: the flushing assembly includes a flushing balloon, which is connected to a three-way valve via a liquid tube.

[0012] As a further preferred embodiment of this utility model: a connecting cap is provided on the flushing balloon, and the liquid tube is connected to the connecting cap.

[0013] As a further preferred embodiment of this utility model: a threaded connector is provided at the tail end of the flushing pipe, and the threaded connector is threadedly connected to the port of the three-way valve.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This kit, with its flushing tube conforming to the physiological curvature of the human urethra, allows for easy insertion into the bladder. By controlling the three-way valve, saline solution from the saline bag is first squeezed into the flushing balloon. Then, the flushing balloon is connected to the flushing tube, and squeezing the balloon forces the saline solution from the balloon into the flushing tube, which then flows into the bladder through a side hole at the tube head, completing the bladder flushing process. Simultaneously, releasing the flushing balloon, under negative pressure, allows tissue fragments and blood clots from the bladder to be aspirated into the flushing balloon through the side hole and removed from the body. The operation is convenient and greatly reduces the risk of secondary surgery for patients undergoing transurethral resection of bladder cancer, making it highly practical.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0020] Please see Figure 1-2 This embodiment provides a bladder irrigation kit, including an irrigation tube 1 conforming to the physiological curvature of the urethra, a fluid channel 10 inside the irrigation tube 1, and a side hole 6 at the head of the irrigation tube 1 communicating with the fluid channel 10. The design of the side hole 6 allows the irrigation fluid to flow out from one side of the head of the irrigation tube 1, avoiding the problem of damage to human tissue caused by opening a hole at the end of the irrigation tube 1 when the irrigation tube 1 is inserted. A three-way valve 2 communicating with the fluid channel 10 is connected to the tail of the irrigation tube 1. The three-way valve 2 is connected to the fluid supply component and the irrigation component.

[0021] The fluid supply assembly is used to provide flushing fluid, and includes a saline bag 3, which is connected to a three-way valve 2 via a connecting pipe 7.

[0022] The flushing assembly is used to flush the flushing fluid into the bladder through the flow channel 10 and aspirate any tissue fragments or blood clots generated after flushing the bladder. It includes a flushing balloon 4, which is connected to a three-way valve 2 via a fluid tube 8. To facilitate cleaning and disinfection of the flushing balloon 4, a connecting cap 5 is provided on it. The fluid tube 8 is connected to the connecting cap 5. As a standard design, the end of the fluid tube 8 should extend into the flushing balloon 4.

[0023] In addition, in order to facilitate the connection between the flushing pipe 1 and the three-way valve 2, and to disinfect the various components after use, a threaded connector 9 is provided at the end of the flushing pipe 1, and the threaded connector 9 is threadedly connected to the port of the three-way valve 2.

[0024] It should be noted that the connection between the three-way valve 2 and the connecting pipe 7 and the liquid pipe 8 is a routine operation familiar to those skilled in the art. Preferably, the three-way valve 2 is simply inserted into the connecting pipe 7 and the liquid pipe 8. After use, they can be separated and sterilized. The connecting pipe 7 and the liquid pipe 8 can also be used as disposable medical supplies, which is a routine operation and will not be described in detail here. In addition, as a standard design, the threaded interface diameter of the three-way valve 2 should be consistent with the interface diameter of the infusion tubing currently used in clinical practice for easy connection.

[0025] In clinical application, after assembling the kit, the irrigation tube 1 is inserted into the patient's bladder along the urethra. The three-way valve 2 is controlled to connect the connecting tube 7 to the irrigation balloon 4. Then, the saline bag 3 is squeezed to allow saline solution to enter the irrigation balloon 4. Next, the three-way valve 2 is controlled to connect the liquid tube 8 to the irrigation tube 1. The irrigation balloon 4 is squeezed, and the irrigation fluid inside the balloon is forced into the irrigation tube 1 by air pressure. The fluid is then flushed into the bladder through the side hole 6 at the end of the irrigation tube 1, achieving bladder irrigation. Subsequently, the irrigation balloon 4 is released. Under negative pressure, tissue fragments and blood clots in the bladder are aspirated into the irrigation balloon 4 through the side hole 6. The irrigation balloon 4 is then separated from the connecting cap 5, and the tissue in the irrigation balloon 4 is emptied. The irrigation balloon 4 is then reconnected to the connecting cap 5. This process is repeated to achieve multiple irrigations. The pressure applied to the irrigation balloon 4 by medical staff can be determined according to actual clinical needs to achieve the irrigation and aspiration functions. This is a routine operation familiar to medical staff and will not be described in detail in this application.

[0026] It should be noted that during repeated flushing, tissue fragments or blood clots may remain on the inner wall of flushing tube 1. These will not affect the flushing effect of the flushing solution on the bladder. After the entire flushing process is completed, flushing tube 1 can be cleaned.

[0027] After bladder irrigation and aspiration are completed, the kit should be separated, and the irrigation tube 1, three-way valve 2 and irrigation balloon 4 should be cleaned and disinfected to remove any residual blood clots and tissue fragments inside the irrigation tube 1, three-way valve 2 and irrigation balloon 4. The saline bag 3, connecting tube 7 and fluid tube 8 can be selected as disposable items. If they are to be reused, they should also be disinfected. This is routine medical knowledge familiar to those skilled in the art and will not be elaborated further.

[0028] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and features of this application. Solutions or features that are prior art or common knowledge to those skilled in the art will not be described in detail in the above embodiments.

[0029] Furthermore, the technical solutions of this application are not limited to the above embodiments. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
