Description
Technical Field
The utility model relates to the technical field of medical instruments, in particular to an integrated bladder perfusion and drainage dual-purpose device.
Background
Bladder Cancer (BC) is one of the most common malignant tumors in the urinary system. Non-muscular invasive bladder cancer (non-muscle invasive bladder cancer, NMIBC) and muscular invasive bladder cancer (muscle invasive bladder cancer, MIBC) are classified, wherein about 75% to 85% of bladder cancers can be diagnosed as NMIBC. The first step in NMIBC treatment is surgical treatment to achieve the goal of tumor resection, but the recurrence rate is as high as 60% -70% within 1 year after surgery. Studies show that the postoperative bladder perfusion treatment can effectively prevent the progress and recurrence of NMIBC, and the principle is that chemotherapeutics or immune preparations are injected into the bladder through a urinary catheter to directly act on tumor lesions which are scattered in the operation or remain on wound surfaces, so that the recurrence frequency is reduced, and the tumor progression or the risk of metastasis is reduced.
The most commonly used device for the clinical bladder-activating perfusion treatment at present adopts a 50ml syringe to prepare medicines, then a 50ml feeder is used for injecting medicines, and then the feeder is connected with a catheter for bladder perfusion. Because the opening end of the catheter is large, the connection port of the 50 injector is not matched with the opening of the catheter, and the liquid medicine is always leaked when the nipple of the injector is connected with the opening of the catheter, the medicine is required to be injected into the food injector from the 50ml injector to be properly connected with the catheter, and bladder irrigation is implemented. For patients who use single-cavity/double-cavity catheters for infusion, the infusion device is also required to be separated after infusion, and then the infusion device is connected with a urine bag, so that the infused medicine can be drained.
However, the whole operation flow has several links of drug leakage and waste:
the process of injecting the medicine into the feeder often causes part of the medicine to adhere to the inner side surface of the syringe barrel, thereby causing waste; (2) The operation process of injecting the medicine into the feeder easily causes medicine leakage, and causes medicine waste and environmental pollution; (3) The urinary catheter and the feeder are separated, medicines are easy to leak in the process of reconnecting the urinary bag, and the hemostatic forceps are manually used for clamping and stopping flow, so that the workload is increased. The infused medicine is often a chemotherapeutic medicine or an immune preparation, has great toxicity, and threatens the physical health and life safety of operators and workers in the same environment.
Medical staff can inject the prepared medicine into the infusion bag, the infusion bag is connected with a bladder irrigator, the head of the irrigator is connected with a urinary catheter for bladder perfusion, and the perfusion speed can be adjusted. For a conventionally indwelling single-cavity catheter, the method still has the problem that the catheter needs to be separated from the flushing end or the drainage end twice, so that the risk of drug leakage is increased, and meanwhile, the workload is increased.
In recent years, many scholars have invented the adapter of the injector and the catheter or the closed two-head injector, which satisfies the bladder perfusion effect to a certain extent and reduces the medicine waste to a certain extent, but the exposure risk still exists in the process of the adapter, and the perfusion amount is limited, thus increasing the implementation difficulty for some larger medicine perfusion; the infusion speed is difficult to master, and the infusion is too fast, so that the liquid medicine is easy to stimulate the patient to obviously cause discomfort and pain of the patient, the pain of the patient is increased, and the treatment compliance is reduced.
Therefore, providing an integrated bladder perfusion and drainage dual-purpose device with controllable perfusion capacity without multiple transfer of the injector, the urinary catheter and the urine bag becomes an important technical problem to be solved by the person skilled in the art.
