Pressure Sensor and Temperature Sensor used in Hemodialysis Treatment
As it is known, Hemodialysis is currently the most efficient way to treat patient of acute or chronic Kidney failure. The machine works as human kidney to take blood out of the body, exchange substances in the dialyzer through extracorporeal circulation, remove metabolic waste and excess water, and then return to the body through the vein.The treating process cannot be interrupted and it must be ensured that the indicators in the dialysis operation are in normal stage in order to guarantee the clinical treatment. Various sensors, including pressure sensors, temperature sensors, etc., play an important role in the entire system.Pressure sensor monitoring blood flow pressureAccurate measurement of dialysate and venous pressure is critical to patient safety during dialysis treatment. At present, some miniature pressure sensors, especially MEMS pressure sensors, are used in various fine liquid monitoring devices such as dialysis machine.In such machine, the main fu...
