Description
Technical Field
The utility model relates to the technical field of medical instruments, in particular to a simple single-cavity urinary catheter for disposable bladder perfusion.
Background
Bladder cancer is one of the most common malignancies of the urinary system. In China, the incidence and mortality of bladder cancer have been on the rise in recent decades. According to the national cancer research report of 2018, about 7.81 ten thousand new cases of the national bladder cancer account for 2.05 percent of all new cases of malignant tumors; the death cases are 3.21 ten thousand, and account for 1.40 percent of all malignant tumor death cases. Therefore, bladder cancer has become one of the malignant tumors that seriously affect human health and survival. Bladder cancer can be classified as non-muscle invasive bladder cancer (NMIBC) and Muscle Invasive Bladder Cancer (MIBC). NMIBC accounts for approximately 75% of initial bladder tumors and MIBC accounts for approximately 25% of new bladder tumors.
The primary treatment modality for NMIBC is transurethral resection of bladder tumor (TURBT), but bladder tumors are still prone to recurrence and progression after simple TURBT surgery. Studies have shown that post-operative bladder perfusion therapy plays a crucial role in reducing the recurrence and progression of bladder cancer. The basic process of bladder perfusion therapy is as follows: the patient with bladder cancer lies on the treatment bed; the clinician makes occupational protection, disinfection and towel paving; inserting a catheter through the urethra under aseptic operation to fully extract urine in the bladder; then slowly injecting the prepared therapeutic drugs (such as chemotherapeutic drugs, BCG and the like) in a 50ml syringe into the bladder; the ureter is pulled out immediately after the medicine is filled into the bladder; the patient is ordered to change the body position intermittently to make each wall of the bladder fully contact with the medicine during the period of keeping the medicine in the bladder, and the medicine is automatically discharged about 1 hour.
In clinical work, a common catheter for bladder perfusion is a common double-cavity catheter. A double-cavity catheter is characterized in that two cavities are formed in one catheter as the name suggests. The first chamber is a drainage chamber, which drains urine from the bladder. The second cavity is an air sac cavity, when the ureter is placed in the bladder, a small amount of physiological saline or gas is injected into the second cavity, the front end of the ureter can bulge an air sac, and the ureter is fixed in the bladder and is not easy to fall off, so that the purpose of keeping the ureter for a long time can be achieved. However, the use of a common dual lumen catheter during bladder perfusion is subject to the following problems:
firstly, the ureter can be pulled out immediately after the medicine is filled into the bladder, and the air sac cavity of the double-cavity catheter is actually in an idle state, so that serious waste of medical materials is caused (according to medical guidelines, the bladder filling of each patient needs to be carried out for nearly 18 times per year according to the specification, and about 110 ten thousand catheters used for bladder filling in China are roughly estimated according to the incidence rate of bladder cancer in China);
secondly, therapeutic drugs are injected through the drainage cavity of the double-cavity catheter, and the port of the cavity is not completely matched with the head end of the injector, so that the drugs are easy to leak out in the drug injection process, and environmental pollution and drug waste are caused;
and the head end of the double-cavity catheter has an air bag wall wrapping, the diameter of the head end is larger than the diameter of a simple urinary catheter, so that in the process of inserting the urinary catheter, the air bag wall structure of the head end can bring obvious discomfort to a patient, especially to a patient with urethral stricture.
SUMMERY OF THE UTILITY MODEL
Aiming at the technical problems, the utility model aims to provide a simple single-cavity urinary catheter for disposable bladder perfusion, which can reduce the waste of medical resources, prevent the leakage of chemotherapy drugs, obviously improve the experience of patients in the treatment process and relieve the pain caused by diseases.

The disposable bladder is perfused and is used simple type list chamber ureter, preferably, the ureter tip is the cone structure of blunt round in the point.
Due to the adoption of the technical scheme, the utility model has the following advantages:
the utility model designs a single-cavity urinary catheter special for bladder perfusion, which consists of a urinary catheter body and a connector, and omits an air bag cavity of a common double-cavity urinary catheter, thereby avoiding the waste of medical resources and reducing the discomfort brought to a patient in the urinary catheter inserting process; the port of the connector is matched with the shape and the size of the head end of the injector, so that the medicine leakage in the injection process is effectively avoided; in addition, the connector is internally composed of a one-way valve structure (liquid can not enter only), and when the injector is pulled out after the medicine is filled into the bladder, the one-way valve is closed, so that the medicine in the bladder is prevented from flowing back from the ureter.
