Description
Technical Field
The invention relates to the technical field of medical appliances, in particular to a turbine type bladder irrigation device.
Background
Bladder cancer typically occurs in the urothelial cells and is the fifth most common cancer type in the world, with an estimated 15 million new bladder cancers per year and over 5 million deaths per year. The most common type of bladder cancer is urothelial cancer, which accounts for about 90%. After painless hematuria symptoms are found in most patients, early diagnosis can be achieved, the patients receive operation treatment in time, but the postoperative recurrence and the progression rate are high, and about 78% of patients relapse within 5 years. The survival rate of bladder cancer is related to the stage of the tumor, the type of pathology and the time of diagnosis. The 5-year survival rate for stage IV bladder cancer is only 15%.
Prostate hyperplasia is a common disease and a high incidence of diseases of the urinary system, and is also called benign prostate hyperplasia, namely prostatic hyperplasia, when a series of clinical symptoms are caused by the progress of the disease. The disease is well developed in the elderly, more than half of people over 50 years old suffer from benign prostatic hyperplasia, and more than 80 years old can reach 90%, and is mainly related to androgen hyposecretion of the elderly men. The clinical manifestations are frequent micturition, urgent micturition, nocturia, dysuria, etc., and the disease progression may also appear hematuria, urine retention, urinary tract infection, hydronephrosis, even affect the kidney function and cause renal failure, seriously affect the life quality of the patient. The disease brings certain difficulties for diagnosis and treatment due to complexity, variable symptoms and long course of disease.
For early stage bladder cancer and benign hyperplasia of prostate, the main current surgical approaches are transurethral bladder tumor, prostatic electrosurgery. After the electrostomy, bleeding or active bleeding may be caused by inaccurate hemostasis on the cut surface and the cut edge, if the operation is not done, blood is locally accumulated and coagulated into blood clots, and the bladder is filled after gradual increase and falling off, which causes acute urinary retention, bladder irritation and bladder spasm, and in severe cases, the kidney function is affected by the reverse transmission of pressure. A bladder wash is routinely required after surgery to remove blood and blood clots. Generally, during flushing, the coagulation condition of the bladder is evaluated through the color of output liquid of a bladder output tube, and if the color is darker, the flushing speed needs to be increased to prevent local stagnation of blood and blood clots; if the color is light or clear, the flushing speed can be reduced, even after observation for hours, the bladder flushing can be stopped. The above-mentioned adjustment of the irrigation speed requires frequent monitoring by doctors and nurses.
In addition, because some patients have formed blood clots in the bladder, clinically, the large syringe is directly used for powerful suction outside to remove the blood clots; the operation is complicated and the pain is brought to the patient.
