Description

Technical Field

[0001] The utility model relates to the technical field of screw caps for bladder instillation chemotherapy, in particular to a bladder instillation chemotherapy catheter. Background Art

[0002] Transurethral resection of the prostate and transurethral resection of bladder tumors are common surgical procedures in urology. Bladder irrigation is often required after surgery. Bladder irrigation is a method of using a catheter to inject a solution into the bladder and then drain the injected liquid out using the siphon principle. However, the existing catheters used for bladder instillation chemotherapy still have certain defects when used, such as;

[0003] For example, a double-lumen urinary catheter and a urinary catheter device with publication number CN217697616U, in which the double-lumen urinary catheter provides a drug injection cavity to provide a flow path for the drug solution for operations such as bladder flushing and instillation of chemotherapy drugs into the bladder, and can achieve bladder flushing and instillation of chemotherapy drugs into the bladder without removing the catheter, which makes the operation simpler and also reduces the discomfort of the patient caused by repeated disassembly and assembly of the catheter.

[0004] However, the double-lumen urinary catheter and urinary catheter device still have the following disadvantages in actual use:

[0005] The injected liquid is discharged through the drainage cavity. In actual use, it is necessary to use a drainage bag to plug the drainage cavity for drainage. The need to replace the drainage bag makes the overall treatment process cumbersome and easily leads to a longer treatment time, which can easily cause patient discomfort and affect subsequent treatment. The drainage bag needs to be replaced for use, which not only increases the risk of chemotherapy drug spillage, but also increases the use of drainage bags, thereby increasing the cost of treatment.

[0006] In view of the above problems, it is urgent to make an innovative design based on the original catheter used for bladder instillation chemotherapy. Therefore, we proposed a catheter used for bladder instillation chemotherapy that can well solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to provide a urinary catheter for bladder instillation chemotherapy to solve the problem proposed by the above-mentioned background technology that the injected liquid is discharged through the drainage cavity in the current market. In actual use, it is necessary to use a drainage bag to plug the drainage cavity for drainage. The need to replace the drainage bag makes the overall treatment process cumbersome and easily leads to a long treatment time, which easily causes discomfort to the patient and affects the subsequent treatment. In addition, the drainage bag needs to be replaced for use, which not only increases the risk of chemotherapy drug spillage, but also increases the use of drainage bags, thereby increasing the cost of treatment.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a urinary catheter for bladder instillation chemotherapy, comprising a set pipeline;

[0009] The end of the pipeline is provided with a liquid outlet, the side end of the liquid outlet is threadedly connected to a mounting cap through a connecting assembly, and the side end of the mounting cap is provided with a syringe, through which the liquid inside the pipeline is sucked;

[0010] A connector is fixed to the side end of the mounting cap, and a protective cover is connected to the connector.

[0011] Preferably, the connection assembly comprises a connector installed at the side end of the liquid outlet, a valve is provided on the connector, and the mounting cap is threadedly connected to the connector.

[0012] Preferably, the syringe is provided with an operating assembly, and the operating assembly includes a needle installed on one side of the syringe; the needle is connected to the syringe.

[0017] Preferably, the limit block and the arc block are symmetrically arranged, and a protective pad is connected to the inner side of the limit block and the arc block.

[0018] Compared with the prior art, the utility model has the following beneficial effects: the urinary catheter for bladder instillation chemotherapy is connected to the liquid outlet by using the cooperation of the mounting cap and the connecting assembly, and the thread on the outer side of the mounting cap is used for connection, so that the overall connection is stable, and the risk of drug spillage is reduced. The injected liquid is sucked out by the syringe at the side end of the mounting cap, so that the overall operation is convenient, which not only reduces the treatment time, but also improves the comfort of the patient, does not need to use a drainage bag for drainage operation, reduces the cost of treatment, and passes the overall safety of use. The specific contents are as follows:

[0019] (1) The mounting cap is connected to the liquid outlet through a connecting assembly, which facilitates the subsequent extraction of liquid, making the whole bladder instillation chemotherapy operation convenient, which not only reduces the treatment time and improves the patient's comfort, but also reduces the use of unnecessary drainage bags in the clinic, saves resources, and reduces the cost of treatment;
