Abstract

The invention discloses a pressure control type catheter, which relates to the technical field of medical equipment. The pressure control type catheter comprises a catheter, the tail end of the catheter is connected with a one-way valve, the bottom of the one-way valve is fixedly provided with a water bag communicated with the one-way valve, and the bottom of the water bag is connected with a resistance one-way valve. The front end of the catheter is inserted into the bladder, the tail end of the catheter is connected with the water bag through the one-way valve, when urine exists in the bladder, the overall pressure in the bladder is increased, the urine is squeezed by the pressure, a squeezing acting force is generated on the one-way valve, then the urine flows into the water bag through the catheter, when there is more urine in the bladder, the water bag can be rapidly filled with urine through the catheter, a worker judges whether the urination speed needs to be increased or not according to the filling degree of the urine in the water bag and the opening condition of the resistance one-way valve, the worker can manually squeeze the water bag to increase the pressure in the water bag, then the urine pushes the resistance one-way valve to be opened greatly, and the urine discharge speed is increased.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a pressure-controlling urinary catheter. Background technique [0002] A urinary catheter is a tube that is inserted into the bladder from the urethra to drain urine. It is a pipeline made of natural rubber, silicone rubber, or polyvinyl chloride (PVC). After the catheter is inserted into the bladder, there is a balloon near the tip of the catheter to fix the catheter in the bladder so that it does not come out easily, and the drainage tube is connected to a urine bag to collect urine. [0003] When various reasons cause the patient's bladder to be full and unable to urinate, or to prevent overfilling of the bladder and making it difficult to urinate, it is necessary to use a catheter to solve such problems. Most intracavitary operations in urology are performed on the basis of fluid flushing. When a large amount of fluid enters the urinary system cavity, the pressure ...
