Description
technical field [0001] The invention belongs to the technical field of medical devices, and relates to a balance device, in particular to an automatic liquid dosing volume balance device for blood purification. Background technique [0002] Blood purification techniques include hemodialysis, filtration, adsorption, and plasma exchange, among which hemodialysis is the most common. The patient's renal failure results in the inability to excrete metabolic waste, and the purpose of hemodialysis is mainly to remove the patient's metabolic waste, especially excess water. During the blood purification process, the balance device controls the balance of blood entering and exiting the human body to ensure the effect of blood purification for patients. When the existing blood purification device is in use, due to long-term use, severe mechanical wear leads to poor balance of the balance device. In clinical use, poor balance often leads to adverse events such as hypotension or even bo...
