Intrarenal pressure monitoring and control system

Abstract

The invention discloses an intrarenal pressure monitoring and control system which comprises an optical fiber pressure sensor, a signal tuner, a demultiplexer, a displayer, a feedback controller and a medical injection pump. The optical fiber pressure sensor is placed into the kidney through an operation endoscope operating hole and is connected with the signal tuner through an optical fiber. The optical fiber pressure sensor is placed into the kidney through the operation endoscope operating hole and used for conducting real-time pressure monitoring on a kidney intracavity operation region. The signal tuner is connected with the signal input end of the demultiplexer. The signal output end of the demultiplexer is respectively connected with the displayer and the feedback controller. The feedback controller is connected with the medical injection pump. Medical perfusate is injected into the medical injection pump through a conduit, and is controlled by the medical injection pump to be injected into the kidney cavity through a conduit. According to the intrarenal pressure monitoring and control system, the intrarenal real-time pressure can be accurately measured and fed back to the medical injection pump, the injection pressure of the medical injection pump is reduced immediately when the pressure is increased to the alarm value, the intrarenal low-pressure injection is maintained, and it is ensured that various intrarenal operations can be safely carried out.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an intrarenal pressure monitoring and control system. [0002] Background technique [0003] The physiological function of the kidney is to filter the blood through the pressure difference between the glomerular inlet and outlet arteries, and to excrete metabolites and harmful substances from the body through urine. When the urine outlet channel (renal pelvis, ureter, bladder, urethra) is blocked (stones, tumors, deformities, trauma, etc.), the pressure in the kidney increases, forming hydronephrosis, and eventually leading to renal failure. Therefore, it is extremely important to maintain a low pressure state in the kidneys. [0004] Due to the natural connection between the urinary tract and the outside world, minimally invasive endoscopic surgery is often chosen for the treatment of urinary system diseases. During the whole process of endoscopic treatment...

Problems solved by technology

Both of these two measurement methods have the disadvantages of poor sensitivity, low precision, many interference factors, and unstable measurement results. Microscopic air bubbles in the pipeline, jitter during operation, and blockage of debris after crushing stones can cause the measurement value to be high. distortion or even measurement failure
