The design and development of Dialysis Machines are becoming more and more mature, but due to a variety of objective reasons, the equipment components are easily worn out and malfunction. Therefore, in order to effectively ensure the normal operation of the machine and allow the patient to obtain continuous and stable treatment, it is necessary to be familiar with the common breakdowns of the Dialysis Machines and to be able to perform timely maintenance and maintenance.
The Dialysis Machine mainly includes two parts: blood monitoring alarm system and dialysate supply system. The blood monitoring alarm system (ie, the blood circuit section) includes heparin pumps, blood pumps, air monitoring and venous pressure monitoring; the dialysate supply system (ie, the waterway section) includes a temperature control system, a liquid distribution system, a conductivity monitoring system, and degassing. System, blood leak monitoring and ultrafiltration monitoring.
The working principle of the Dialysis Machine: the patient's blood is pumped out through the blood pump, and the heparin pump injects appropriate amount of heparin to perform anticoagulation treatment on the blood, and the dialysate supply system degassing the dialysate concentrate and the dialysis water and heating it according to certain conditions. After mixing, the dialysate is prepared and then the blood and the dialysate act on the hemodialyzer. The blood completes the process of solute diffusion, permeation and ultrafiltration, and then returns to the patient through the air detector. At the same time, the dialysis fluid after the action is leaked. The detector is drained as waste. This process continuously circulates and reciprocates, excreting metabolic wastes and excessive water and electrolytes generated in metabolic processes inside the body, thus achieving the purpose of treatment.
